Provedor de dados: 13
Autores: Грезе И. И.
В монографии обобщены многолетние исследования автора и литературные данные по биологии амфипод Черного моря. Рассматриваются их систематический состав (111 видов и 5 подвидов) и зоогеографическая принадлежность. Изучены распределение амфипод средиземноморского комплекса в зависимости от экологических условий, состав пищи и пищевые потребности массовых и наиболее обычных видов, определена их численность, биомасса и общие запасы амфипод этого комплекса в Черном море. Подробно освещены основные черты биологии 10 массовых видов - размножение, рост, годовая динамика размерного состава популяций. На этой основе определены велечины удельной продукции, оценено общее значение амфипод в биодинамике моря и роль этой группы в его трофической системе. Рассчитана на...

Autores: RAMALHO, F. S.; NAGAI, V.
Testou-se o comportamento de 49 cultivares de milho, incluindo variedades e híbridos comerciais brasileiros assim como raças da América Latina, em relação a Stophilus oryzae (Linné, 1763). Fêz-se o estudo com milho debulhado, em condições de laboratório. Adotou-se o metôdo de confinamento, para avaliar a resistência dos cultivares a infestação do gorgulho. Houve diferença significativa no número de gorgulhos emergidos, assim' como para o período de desenvolvimento. Houve correlação positiva entre o peíodo de desenvolvimento e a dureza da ponta dos grãos, mas não houve correlação com a dureza costal. Encontrou-se uma correlação negativa entre número de gorgulhos emergidos e assim como para o período de desenvolvimento. O comportamento das cultivares de...

Mesure densimétrique de la salinité. Table donnant la salinité en fonction de la densité et de la température
Provedor de dados: 5
Autores: Leroy, C.; Cadiou, Yvon; Delaporte, Francis.
Parmi les méthodes physiques ou chimiques pérmettant de mesurer la salinité de l'eau de mer, la densité est certainement la plus simple et surtout celle qui ne nécessite pas un appareillage coûteux puisqu'il suffit de disposer d'un aréomètre, d'un thermomètre et d'une éprouvette (coût entre 160 et 300 F.,selon la précision désirée). Cette méthode est peu précise mais, dans bien des cas, elle peut suffire, notamment lorsqu'on désire obtenir la salinité avec une précision comprise entre l'unité et la première décimale. La table qui suit a été établie dans ce but et il conviendra, si on désire une précision plus grande, d'utiliser une autre méthode : chlorinité ou conductivité électrique.

La Baie de BOURGNEUF est située sur le littoral atlantique juste au Sud de l'estuaire de la LOIRE dont elle est séparée par la pointe de ST GILDAS. Cette baie ne serait qu'une simple ondulation du trait de côte si l'Ile de NOIRMOUTIER ne la séparait de l'océan sur une vingtaine de kilomètres. Ainsi ne subsiste-t-il que deux ouvertures, l'une au Nord qui s'étend sur une largeur de 12 kilomètres entre la pointe de l'HERBAUDIERE et celle de ST GILDAS, l'autre au Sud, large de 800 mètres, qui n'est en fait qu'un étroit goulet entre la pointe de la FOSSE et celle de NOTRE DAME DE MONT. Du point de vue milieu naturel - comme ailleurs du point de vue historique et administratif - la baie fait le contact entre le littoral breton (falaises, rias, criques) et les...

Influence de la pollution urbaine sur la vitalité des herbiers à posidonies dans le golfe de Giens (Var)
Provedor de dados: 5
Autores: Maggi, Pierre; Gruet, Yves; Lassus, Patrick; Kalifa, Francis.
Les posidonies sont des phanérogames marines qui existent actuellement en deux endroits du globe : en Méditerranée (Posidonia oceanica DELILE) et sur les côtes sud de l'Australie (P. australis J.D. HOOKER). En Méditerranée, l'herbier de posidonies occupe une grande partie des fonds meubles de la zone photophile de l'étage infralittoral (PÉRÈs et PICARD, 1964). Il joue un rôle capital dans la fixation des sédiments meubles et constitue un milieu privilégié pour le développement et la croissance de nombreuses espèces animales marines.

La majorité des pays riverains de la mer du Nord, de l'Atlantique et de la Méditerranée se sont engagés, par différents accords internationaux, à interdire les déversements et rejets en mer de substances nocives. C'est ainsi que parallèlement à certains métaux lourds et produits organohalogénés réputés toxiques et accumulables, les composés organosiliciés font l'objet d'une interdiction d'immersion lorsqu'ils sont toxiques et non biodégradables.

Expérience de repeuplement des fonds à partir de produits d'écloserie
Provedor de dados: 5
Autores: Audouin, Jacques; De Kergariou, Gabriel.
Over the last decades, the fishing effort focused on crustaceans and especially on the lobster has continued to increase. This way, the number of pots used by each boat has grown from a few dozen to several hundred. This process lead to an overexploitation of the seabed and the catches do not go over 400 tonnes/years despite the increase of the means involved. Consequently, it has been necessary to implement a number of new measures to protect the lobster stock, and some restricted areas have been created off the French coasts.

La famille des Haploniscide (Isopodes, Asellotes) : discussion systématique et phylogénique
Provedor de dados: 5
Autores: Chardy, Pierre.
Systematic of the Haploniscidae family is cleared by two approaches : phenetic relationships between species through a multiple criteria analysis and phylogenetic attempt based on a few number of characters of which the evolutive meaning is discussed. Choice and coding of characters, taxonomic distance and mathematical methods are commented. Phenetic classification is expressed by two complementary techniques : ordination (Analysis of Correspondences, CORDIER, 1966) and hierarchy (cluster analysis of Roux, 1968). The resulting scheme provides a picture of the morphological affinities between the 5 genus and the 73 species of this family ; divisions inside genus Haploniscus are defined. A phylogenetic hypothesis, deduced by the minimum steps methods for...

Autores: Buestel, Dominique; Arzel, Pierre; Cornillet, Paulette; Dao, Jean-claude.
It is attempted to produce large quantities of 25 mm scallop juveniles suitable for restocking the beds. A first breeding experiment in laboratory gave a very low survival rate : about 1% from the D larvae stage to reach the size of 1 mm. The growth after metamorphosis is very irregular and slow, compared to the datas obtained in natural environment. An experimental programme of spat collection in natural environment, completed by hanging culture has been conducted. An average number of 300 spats (size 15 mm) per collector has been obtained in 1976. Banging culture allows to reach the size of 25 mm three months after settlement with a very good survival rate. The yield of a large number of spat from collectors seems to demonstrate that there is a future...

Provedor de dados: 5
Autores: Quero, Jean-claude; Verron, R; Cattin, Y.
During 1976, some rare fishes were observed in la Rochelle, especially Heptranchias perlo (Bonnaterre, 1788) (one specimen), Trachiptetus arcticus (Brünnich, 1771) (two specimens), Zenopsis conchifer (Lowe, 1852) (one specimen), Nesiarchus nasutus Johnson, 1862 (four specimens), Pholis gunnellus (Linné, 1758) (one specimen) as also Pseudotriakis microdon Capello, 1868 (one specimen), Serranus cabrilla, (Linné, 1758) (two specimens) and Torpedo nobiliana Bonaparte, 1835 with two different forms. On the other hand, the authors found one albino fish and four remarkably large fishes. They also observed 6 species of fishes from the Bay of Biscay belonging to a colder fauna and 5 species of fishes from the Bay of Biscay belonging ta a hotter fauna. NOT...

L'exploitation des cephalopodes - situation et perspectives
Provedor de dados: 5
Autores: Mesnil, B.
The dwindling of the stocks of some marine animals traditionally fished is driving the producers to consider the exploitation of species which were seen as of lesser interest up to now. Among the latter, cephalopods hold a specific position. In the first place, they are not a new resource so to speak, having been eaten in Asian and Mediterranean countries for a long time, and, above all, they've been the object of a growing interest for a few years now. It is encouraging to see that this tendency is very distinct in our country where it can be thought that producers and consumers are now aware of the value of this abounding species. The actions aimed at optimising their exploitation are thus facilitated but they suffer from the imprecision of the...

Autores: Aldebert, Yvonne; Carries, Claude.
In this paper are given the first results of a quantitative study of the spawning of Pilchard Sardina pilchardus in the Gulf of Lion~during Winter 1975 and Winter 1976. The mean density of eggs at each station and their average abundance in the spawning area were estimated. The incubation time of eggs depending upon temperature was also calculated. En 1975 et 1976 une étude de la reproduction de la sardine dans le Golfe du Lion a été réalisée. Les premiers résultats de cette étude, qui a pour but d'évaluer quantitativement la ponte de cette espèce, permettent de donner une estimation moyenne de l'abondance des oeufs au cours d'une campagne. La durée de l'incubation en fonction de la tempé­rature a d'autre part été déterminée.

Provedor de dados: 5
Autores: Auger, Christian; Grizel, Henri; Tige, Gilbert; Langlade, Aime; Rabouin, Marie-agnès.
Breeding Crassostrea gigas was conducted in three rivers of Morbihan (Brittany France). During one year, every four months, their increasement was examined. In one of these rivers, oysters showed, however their age and their origin, an abnormal increasement. Shells were very thick, with many chambers. At the opposite, in the two others rivers, oysters did not show that disordered state. Shells were sound and their linear increasement was harmonious

Autores: AQUACOP.
With a view of utilizing to the maximum and raising separately the spawn of Peneid shrimps obtained from captive brood stock, the team of the Oceanographic Center of the Pacific of CNEXO adapted the technic of small volume, high density perfected by the Galveston labora­tory to tropical conditions. The environmental conditions, particularly year-round high temperatures, allowed the development of a simple hatchery, demanding a minimum investment. The water, previously chlorinated, then deahlorinated, is only renewed from the mysis stage onward. Cylindrotheca and Tetraselmis algae produced separately are used for the zoea stage, rotifers for the mysis stage and Artemia nauplii for PI to PS at which point the post-larvae are stocked in ponds.

Hatchery techniques for a controlled environment molluscan maricultural system
Provedor de dados: 5
Autores: Pruder, Gary; Bolton, Ellis; Epifanio, Charles.
The hatchery operation which is part of the Delaware controlled environment system is reliable and trouble free. An abundant supply of quality food is necessary to operate a successful hatchery. The bloodstock, larvae, spat and Juveniles all receive the same two-part algal diet. The temperature for all except the bloodstock is 27-29° C. Sexually mature 16 week oysters are being considered as bloodstock. “astroturf" is being considered as a setting substrate. No assurance exists that our hatchery product which excels within the system would succeed in natural planting.

Knowledges concerning the nature and distribution of present day sedimentary facies on the slope and in the Biscay abyssal plain are very poor, due to the scarcity of available sea-floor samples.Samples from the uppermost section of Reineck cores obtained in six areas of the Bay of Biscay in water depths ranging from 2,000 to 4,800 m allow us to study the evolution of the sediments according to the water depth and geographic localisation.This study suggests that the sediment from the southern part of the bay independently of depth are characterized by a higher amount in terrigenous components (quartz, clay ...).This disparity is explained by the differing phyisiographic setting (broad shelf in the northern part versus narrow shelf and submarine canyon...

Croissance larvaire contrôlée de Penaeus japonicus Bate. Enzymes digestives et changements de régimes alimentaires
Provedor de dados: 5
Autores: Laubier-bonichon, Annie; Van W0rmh0udt, Alain; Sellos, Daniel.
The larval and postlarval development of the shrimp Penaeus japoniaus has been stu­died on the basis of the evolution of nucleic acids, of proteinic compounds, and of digestive enzymes. Cell multiplication was assayed by tracing the evolution of the amount of desoxyribo­nucleic acid (DNA) ; this multiplication was found to be high during nauplius stages. Evolu­tion in time of ribonucleic acid (RNA) was compared with evolution of dry weight and proteins ; the amount of RNA rises considerably during stage zoe. Thus it is thought that during stages nauplius and mysis, cellular hyperplasy takes place, while cellular hypertrophy would aarac- terize stage zoe. The development of a new stock of digestive enzymes takes place during the zoe sta­ge. The variations...

Autores: Loubes, Claude; Maurand, Jean; Comps, Michel; Campillo, Albert.
The sporogony of A. nelsoni is of the apansporoblastic type. Diplocaryons always occur during merogony, never occur during sporogony. Sporoblasts are produced by fission of a multinucleate and elongated plasmodium. Spore morphogenesis begins before the end of the end of the sporoblasts individualization. The polaroplast has a very dense outer area. The genus Ameson is very much like genus Perezia and both are badly classified respectively in the families Nosematidae and Unikaryonidae. The creation of the new family Pereziidae is proposed for both genera.

The objectives of this research are to evaluate the usefulness of waste heat from steam electric generating stations as an inexpensive and suitable source of warmed seawater for use in aquaculture of American lobsters and to develop the techniques and systems necessary for the commercially viable culture of this species. Growth rates of larval and juvenile stage lobsters are significantly greater in effluent of elevated temperature than at ambient ocean temperature. Water quality analyses suggest that concentrations of heavy metals and chlorinated hydrocarbons are similar in each water source. 1 Culture techniques have been developed for the larval and juvenile stages and current research efforts are directed toward controlling reproduction, reducing...

In 1972, chemical analysis of rocks using a dispersive X-ray fluorescence system was shown to be practicable at sea during the "Gibraco cruise" of the R.V. Jean Charcot (Bougault and Cambon, 1973). The same equipment and techniques were used to perform analyses on Glomar Challenger during Leg 37. The aim of this report is to describe the instruments used, the basic routine operations, the problems encountered, and how they were solved. From the experience of analytical work onboard and the precision of the results which is discussed, some brief recommendations are made to IPOD for shipboard chemical analysis. The preliminary results obtained are discussed in terms of chemical units compared to lithological units defined onboard. [NOT CONTROLLED OCR]

Today, the marine environment is threatened. It is in danger ... of death. This fact is not a new one, but it is growing worse, and the seas where the maritime traffic and littoral activities are the heaviest (i.e. the seas along the European coasts) are the most affected by pollution. Of course, the international community takes measures. But the unilateral acts of the States, the lack of compelling power of the international organizations considerably limit those actions and raise the problem of the E.E.C. competences relating to the struggle against the sea pollution. As a matter of Eact, the E.E.C. as an international organization of nine European States and as an organ with compelling power could in an original way help to the protection of the sea...

The Treaty of Rome concerning the E.E.C. says in article 38, "The Common Market spreads over agriculture, and over the commerce of agricultural produces. Agricultural produces mean the produces of the ground, of breeding and fishing". And consequently, the article 40 stipulates : "A common organization of agricultural markets will be established". It is in application of these two articles of the Treaty that a common action in the field of fisheries was established on October 20 th 1970. From now, the organization of maritime fisheries of the nine and above all the organization of the market of fishing produces depends on communautary competence, and so the different organizations of the market, which were various have had to adapt themselves to conform...

Dans la perspective d'une action sur les possibilités de développement de la pêche à Mayotte, une série de missions a été organisée par l'I.S.T.P.M., avec le soutien financier du Secrétariat d'Etat chargé des Départements et Territoires d'Outre-Mer. Les deux premières missions effectuées par M. LEBEAU du 2 au 18 décembre 1976 et du 4 au 13 mai 1977 n'ont pu dépasser le cadre des entretiens avec les autorités locales et les pêcheurs et l'organisation des travaux futurs ; elles ont fait l'objet de rapports antérieurs. Celle de M. BARBAROUX, du 7 au 17 septembre 1977 a bénéficié de moyens matériels et notamment d'une vedette mise à sa disposition par les Services de la Préfecture.

Essai de filetage du grenadier (coryphaenoides rupestris, gunnerus 1765)
Provedor de dados: 5
Autores: Lefranc, Gérard.
La commercialisation du poisson qualifié à tort de "faux poisson" nécessite de la part des technologistes des produits de la mer ainsi que des commerçants un effort constant pour convaincre les consommateurs ; une propagande judicieuse menée par des journaux spécialisés a essayé, à plusieurs reprises, d'éveiller l'opinion publique, mais, devant le peu d'intérêt manifesté, il est de notre devoir de relancer cette action justifiée par la diminution des espèces traditionnelles, par la nécessité d'un transfert de l'effort de pêche vers de nouvelles ressources et par la raréfaction des protéines animales. Les poissons de grands fonds constituent des réserves importantes de substances protidiques qui, malheureusement, sont totalement gaspillées.

Two kinetics of contamination of Carcinus maenas by 59Fe have been determined in relation with the preponderent physico-chemical state of the metal in the experimental medium. The soluble forms seem to be accumulated essentially in internal tissues by biological process when particulate forms are accumulated in tissues in contact with sea water. The whole contamination and the kinetics of contamination of the whole crab Carcinus maenas is dependant of the contamination and the kinetic of contamination of the external tissues, gills and exoskeleton, in contact with sea water.

Génétique des huîtres
Provedor de dados: 5
Autores: Gras, Marie-paule; Gras, Paul.
Following the high mortality which killed the Portuguese oysters Crassostrea angulata cultivated on the French coasts, the massive establishment of Pacific oysters Crassostrea gigas, resisting the disease and the creation of artificial deposits for the latter was decided. In most culture areas, the mortality was estimated at more than 80 % of the stock, but, in some regions, some small populations of Crassostrea angulata subsisted and kept on reproducing. A genetic control of the spawner stocks had to be made. The first step was to know if the oysters living in the same areas were of the same species in order to foresee the next generations and try to improve them (selection).

Développement de la conchyliculture et de l'aquaculture importance pour l'aménagement du littoral
Provedor de dados: 5
Autores: Le Dantec, Jean.
In a document from the General Secretariat of the Merchant Navy (P. 3 - MJ - June 1976), it is written: The coast is a rare asset, limited in essence as it is not interchangeable. Moreover, it is coveted and used by numerous users, sometimes aggressive or very powerful, who often take up the areas that are the richest from a biological point of view. This reality is at the origin of a number of land occupancy issues, all the more when a rational or enhancive preliminary choice has not been made. It can also lead to damages or pollutions, the coastal area being more exposed as rivers carry all the effluents which flow into them from their source to the ocean". Witnessing this competition, it appears that marine cultures need to be considered as very...

La pratique de la culture des huîtres et des moules est si ancienne que l'on a souvent tendance à oublier qu'elle représente la première tentative d'aquaculture marine. L'ostréiculture s'est développée avec le succès que l'on sait depuis un siècle mais le problème de l'approvisionnement en naissain demeure souvent aléatoire, particulièrement pendant certaines crises graves détruisant les géniteurs (épidémies, intempéries, surexploitation des gisements naturels). Depuis une vingtaine d'année, des essais plus ou moins fructueux se sont multipliés pour élever au laboratoire puis dans des établissements spécialisés nommées écloseries, des larves puis du naissain de mollusques. aujourd'hui, les produits des écloseries sont entrés dans le circuit commercial et...

The values of chlorophyll a and A T P are high in May and October but they appear to have no correlation.

Autores: Alliot, E.; Pastoureaud, Annie; Trellu, J.
The development of the digestive system of larvae of Dicentrarahus labrax has been studied. The changes in activities of digestive enzymes from hatching to 30 days have been investigated. 8 activities have been recorded : esterases, a-glucosidase, trypsin, chymotryp­sin, leucinaminopeptidase, alkalin and acid phosphatase, using polyacrylamid gel electropho­resis. All the activities are very weak at hatching j the activities of trypsin, a-glucosidase, alkalin phosphatase increase between 0 and 5 days, decrease slowly and are quite stable from 15 to 30 days. The other activities increase steadily from 0 to 20 days. Relationships between the developmental process of the digestive system and changes in activities are investigated.

Étude du phénomène de "Marée Verte" affectant les baies de Lannion et de Saint-Brieuc
Provedor de dados: 5
Autores: Kopp, Joel.
Depuis 1968, les plages des Baies de Saint-Brieuc et de Lannion sont envahies chaque été par d'innombrables épaves d'algues vertes appartenant aux espèces Ulva lactuca et Ulva rigida. Ce phénomène est connu sous le nom de marée verte. Le flux tasse ces épaves en un cordon littoral de plusieurs mètres de largeur à l'intérieur duquel les algues fermentent en dégageant une odeur très désagréable. Chaque cordon constitue, en outre, une barrière qui rend l'accès à la mer très pénible. Il se compose, en effet, d'une croûte blanchâtre d'apparence sèche et solide mais qui se déchire à la moindre pression laissant apparaître un magma noirâtre et putride dans lequel le promeneur s'enfonce jusqu'à mi-jambe (Fig. 1 à 5).

X-Ray Spectrometric Analysis of Trace Elements in Rocks.Correction for Instrumental Interferences
Provedor de dados: 5
Autores: Bougault, Henri; Cambon, Pierre; Toulhoat, H.
Investigating trace element determination in rocks and taking into account possible instrumental interferences,it is shown that the general relationship between I (net peak intensity) and c (fluorescent element concentration) is (I - Io)M = Ac + B where M is the matrix effect correction factor and A is a constant proportional to the efficiency of excitation; B and Io correspond to the intensities due to, respectively , the scattering (especially, by the sample) of any instrumental interfering radiation, and a possible stray emisision by the instrument itself.Using this equation under optimized conditions allows interferences as high as 200 ppm (if expressed in equivalent concentration) to be compensated without any significant decrease regarding the...

Autores: Aquacop, Aquacop.
In order to specify the limits of the high density larval rearing method (80-100 larvae per liter) in clear water with daily total exchange and to control the water quality evolution, the nitrite and total ammonia were measured. Nitrite concentrations in antibiotic treated tanks stayed law (5 ug N02-N/l) but can reached 40 ug N02-N/l after 41 days in untreated tanks, in spite of daily water exchange. Maximum concentrations of total ammonia were 1.70 ppm N during a 24-hour cycle. In the rearing conditions (pH 7.85 to 8.20, temperature 25 to 28 C) the un-ionized ammonia concentrations were 0.07 to 0.18 ppm N. At thase levels, no specifie larval stress was noted.

Recherche d'une alimentation artificielle adaptée à l'élevage des stades larvaires des poissons. II. Application à l'élevage larvaire du bar et de la sole
Provedor de dados: 5
Autores: Gatesoupe, François-joël; Girin, Michel; Luquet, Pierre.
Various zein-coated artificial diets were distributed either alone or in associa­tion with rotifers to larvae of sea-bass and sole. Utilization of artificial diets alone gave rather unsatisfactory results, whereas , the simultaneous use of these with limited quantity of live-preys proved successful : when a low density of fish was retained (3 to S larvae/litre), it was found that the survival rate after one month for the sea-bass was above 10 p. 100 and for the sole, there was metamorpho­sis up to 71 p. 100.  The analysis of results obtained for the different artificial diets seems to indicate that the superiority of live rotifers is more due to their movement than to their composition.

Etangs solaires à stratification de densité
Provedor de dados: 5
Autores: Hyacinthe, Jean-louis.
In this schema of solar ponds, a limited shallow marine area overlays a dark layer where the solar radiation is absorbed. The interna1 thermal convection phenomenon due to heating is cancelled by the action of an adequate vertical density gradient created by salt dissolving. This gradient has to be kept up against the saline dif fusion. Previous experimentation, in Israël for the main, had shown that, after a long enough period of transition to normal running, high temperatures on the bottom of the order of 90°c, can be obtained. CNEXO, the French National Center for the Exploitation of the Ocean, is interested in trying to transform isolated marine natural areas into solar ponds with power order of 100 kW. An experimentation has been launched to specify...

Production of juvenile lobsters (Homarus americanus) for nutrition research
Provedor de dados: 5
Autores: Castell, J.d.
A simple static system for rearing lobsters (Homarus ameriaanus) through their larval stage is described. The need for frequent daily feeding is overcome by supplying each tank of larvae with newly hatched brine shrimp (Artemia salina) nauplii each day. Survival of SO percent of the larvae to the juvenile stage is routinely obtained with a minimum amount of labour. This system easily provides more than enough juvenile lobsters for use in nutrition trials. These juveniles appear healthier and exhibit greater survival beyond the fourth stage than those reared on frozen adult brine shrimp in a continuous flow system.

Identification des espèces de poissons par électrofocalisation en gel de polyacrylamide
Provedor de dados: 5
Autores: Morel, Marc.
L'électrophorèse des protéines est maintenant une technique couramment utilisée pour identifier les espèces de poissons. Elle s'applique aussi bien à des poissons frais ou congelés qu'à des produits transformés (poissons salés, fumés et, même dans certains cas, en conserve). Le principe fondamental de cette technique repose sur le fait que des particules ionisées peuvent se déplacer sous l'action d'un champ électrique et se séparer différemment selon leur charge.

Il est bien évident que la recherche des sites propices au développement de la conchyliculture doit être orientée en fonction des actions à entreprendre dans une perspective à long terme. Différents thèmes ont été étudiés par les chercheurs de l'ISTPM réunis à Nantes. Pour chaque thème, les réflexions du groupe ont porté sur les exigences des activités préconisées, tant sur le plan des techniques à utiliser, des moyens à mettre en oeuvre, que de leur répartition sur de nouveaux espaces qu'il importe, dès maintenant, de réserver.  D'emblée, il est apparu qu'une place à part devait être faite au littoral méditerranéen, où, du point de vue strictement écologique, de grandes possibilités existent, soit dans les étangs littoraux du Languedoc, du Roussillon et...

Variations des caractéristiques pondérales et des compositions amino-acide et protéique pendant le développement embryonnaire de Palaemon serratus
Provedor de dados: 5
Autores: Richard, P; Ceccaldi, H.j.
Wet and dry weights variations related to mother shrimps length, as well as free amino acids, proteins and lipoproteins concentrations of the eggs, have been measured during embryonic development. Eggs wet weight strongly increases whereas dry weight remains nearly constant. Both are closely correlated to mother shrimp length. Total free amino acids concentration is fourfold higher at hatching than at laying, due to the increase of some amino acids such as proline, glycine, alanine and glutamic acid, whereas the so-called essential ones decrease in percentage, chiefly the tryptophane ratio. The slight fall of the total protein concentration throughout the development is the result of embryonic proteins synthesis from lipoproteins. Aminoaaid composition of...

Macrobrachium rosenbergii (De man) culture in Polynesia : progress in developing a mass intensive larval rearing technique in clear water
Provedor de dados: 5
Autores: Aquacop, Aquacop.
To develop Macrobrachium rosenbergii (de Man) culture in French Polynesia, a high density larval rearing method in clear water for post-larvae mass production has been set up by the "Centre Océanologique du Pacifique". Based on three years of experiments, a production of 60 postlarvae per liter in aOO-liter tank was obtained. The methodology (conical bottom tank, static system with one total daily water exchange, no phytoplankton), the environmental conditions (temperature, light, color of the tank), the water quality control (chlorination, antibiotics, aeration), the larval food (quality and quantity) are given and discussed. The model was used to build a hatchery on a pilot scale (capacity 600,000 post-larvae every 2 months). Due to a high level of...

L'élevage larvaire des poissons marins: chaînes alimentaires et aliments composés
Provedor de dados: 5
Autores: Girin, Michel; Person-le Ruyet, Janine.
The daily food supply is usually considered as the main limiting factor for large scale productions of young marine fish.Collecting natural plancton at sea is an easy way of providing small scale tests with a food of good quality. But the method becomes hardly dependable beyond the scale of the aquarium.Large scale production of juvenile fish became possible, during the last decades, with the development of mass production techniques for some food organisms. Among these organisms, the Branchiopod Artemia salina and the Rotifer Brachionus plicatilis undeniably overcome ; meanwhile the culture of Copepods,the most interesting part of natural plankton, remains mainly at laboratory stage.

Red sea bream culture in Japan
Provedor de dados: 5
Autores: Kittaka, Jiro.
The red sea bream becomes sexually mature when 3 years old. The spawning season extends from April to June. About 100-300 matured males and females are introduced in a large tank of 100-1,000 m3 capacity. The floating eggs are gathered and transferred into a net cage. The optimum incubation temperature ranges from 15.0 to 17.5°C, and the optimum specific gra­vity is higher than 1.023. The newly hatched larvae are introduced into floating tanks hinged in a large concrete tank and cultured for about 10 days. The prelarvae are released into large concrete tanks and cultured for about 20 days. Oyster eggs, rotifers (Brachionus plicatilis), copepods collected by net, and nauplius of Artemia saling are used for feeding individuals in prelarval stage. The...

Toxicite et persistance en milieu marin d'un insecticide derive des benzoylurees: le diflubenzuron.
Provedor de dados: 5
Autores: Alzieu, Claude.
The laboratory tests showed that the diflubenzuron does not present acute toxicity to shellfish and fish, but can affect the survival rate of Artemia salina and Palaemonetes varians, when its concentration rises to the level of its water solubility. The insecticide persistence in sea water had been found to be 3 weeks and its concentration factor in the fish after 52 days of exposure was very low. The use of dimilin in coastal zones for the eradication of caterpillars seems to have an insignificant impact on marine ecosystem, particularly on the molluscs.

Reproduction in captivity and growth of Penaeus monodon, Fabricius in Polynesia
Provedor de dados: 5
Autores: Aquacop, Aquacop.
To develop shrimp fanning in French Polynesia where no indigenous commercial species of penaeid prawn exists, the first step is to select the right species according to the following criteria: maturation and spawning in captivity, mass production of post-larvae, fast growth at semi-intensive density, acceptability of artificial diet, disease resistance and hardiness. This paper presents the results on P. monodon, Fabricius, the largest Indo-Pacific species. Experiments have been conducted in the "Centre Océanologique du Pacifique" in Tahiti Island where the environmental conditions are water temperature range 25-29 C, salinity 35 ppt, pH 8.2.

Depuis le début des travaux d'aménagement entrepris en Loire, de nombreuses modifications ont affecté le cours du fleuve mais également les zones environnantes. De nos jours, la Loire possède encore un potentiel biologique important qu'il faut essayer de préserver en évitant d'y faire des aménagements ayant des conséquences irréparables pour l'avenir. Malgré sa condamnation, il faut souligner que la destruction des vasières de Gron-Méan correspond à la perte des 3/4 des richesses biologiques de l'estuaire. En effet, les chiffres des biomasses que nous avons précédemment donnés montrent que cette vaste zone, à elle seule, était 3 à 4 fois plus riche que l'ensemble de ce qui reste productif en Loire.

The Mont-Saint-Michel is at the end of the Norman-Breton gulf, in the angle formed by Cotentin to the east and Brittany to the south. The pointe du Grouin, to the NW, and the pointe de Champeaux, to the NE, circumscribe it to the north, whereas to the south, its flat coast melts into the Dol Marsh and the polders which border the Couesnon (fig. 1). The bay currently has a marine surface of 37,000 ha, about 3/5 of which is emerged during spring tide. The tidal amplitude is the strongest in Europe with over 14 m. Considering the extreme flatness of the tidal zone, the flow covers very long distances (about 20 km in the axis of the Sélune). This results in some very strong currents which create an important mixing of the water. These currents renew the water...

Presently many mariculture facilities may operate in a reduced manner because of the high cost and limited success of disease control measures. Cultured animals are exposed to conditions of crowding and inadequate nutrition not encountered in nature which promote or aggravate disease outbreak. Culture disease may be introduced into the culture system through an infected wild animal or through the use of contaminated water for the maintenance of cultured fish or shellfish. Mariculture facilities which use contaminated water must find a reliable and economic method for seawater disinfection to prevent disease outbreaks.

Daily food intake of young soles, from 8 to 30 am length, was measured in the labo­ratory at five constant temperatures from 10 to 26°C. The daily consumption (C) was correlated with length (L, cm) and weight (W, g) of the fish, which resulted in the following exponen­tial relationships with temperature (T, °C) : c = O.OOOOll e°'Zb TJ3.20-0.0096T-0.0026T2) n - n nna 0.18T „(1.12-0.013T-0.00055T2) C — 0.Quo e , w .

Recherche d'une alimentation artificielle adaptée à l'élevage des stades larvaires des poissons. I. Comparaison de quelques techniques destinées à améliorer la stabilité à l'eau des aliments
Provedor de dados: 5
Autores: Gatesoupe, François-joël; Luquet, Pierre.
The aim of the present work is to compare different methods employed for increasing the stability to water of diets used for feeding fish larvae. The various methods of protection tested are : - the addition of gelatin to the diet, -  the encapsulation by synthetic (nylon) or natural (gelatin, zein) polymers, - the coating by zein. The water stability of the unprotected diet particles is very low : only 3 % of the diets are recovered by filtration after 4 hours in water. The addition of 10 % gelatin impro­ves slightly this stability (13 to 25). While encapsulation with nylon considerably increases the water-standing capacity of diets (56 to 66 %), the best results are obtained with the particles encapsulated using natural polymers (74 to 79 %).

Etude écologique de l'estuaire de la Gironde - Rapport final
Provedor de dados: 5
Autores: Romana, Louis-alexandre; Marchand, Philippe.
Le programme d'équipement d'Electricité de France prévoit, pour les prochaines années, la construction sur l'estuaire de la Gironde d'une centrale nucléaire dont la réfrigération, pour les quatre tranches de 900Mw est envisagée par une circulation d'eau de mer de type "ouvert". D'une façon générale, le but des recherches et des études confiées au Centre National pour l'Exploitation des Océans (Unité Littoral du Centre Océanologique de Bretagne) est de définir un état écologique de référence, au cours d'un an et demi d'observations sur le terrain, avant le début des travaux d'implantation de la centrale. Les résultats obtenus à l'issue de ce travail doivent permettre : - d'établir le "point zéro" qui sera utilisé par la suite à des fins comparatives, étant...

1967-77: ten years of marine geology and geophysics
Provedor de dados: 5
Autores: Le Pichon, Xavier.
Plate tectonics gave a great stimulus to marine geology and geophysics; in the years since its enunciation there have been major drilling programmes, a new science of global palaeoenvironmental oceunography and much more detailed oceanographic surveYs. The pace shows no sign of slackening-in the next few years the passive continental margins will be muchstudied. [NOT CONTROLLED OCR]

Méthodologie d'étude la masse d''eau : aspects théorique et pratique
Provedor de dados: 5
Autores: Romana, Louis-alexandre; Ryckaert, Mireille.
Le problème de l'échantillonnage des masses d'eau suppose, au préalable, la définition d'un état de référence, de la notion de variation saisonnière et locale.

Although the determination of hydrocarbons in the marine environment is based usually on the same analytical steps, organic solvents extraction, column chromatography purification, and means for hydrocarbons detection and identification, the variations in the equipment and solvent systems included in the different established techniques hinder to obtain a global idea about the oil contamination state of the seas. Many authors and conferences declared the necessity of carrying out a comparative study on the efficiencies of the various published analytical techniques in this field. According to the facilities available in the laboratory, 25 applications of 16 published techniques were applied on a fixed weight of unique sample of sediments, mussels, fishes,...

Autores: Chasse, Claude; Le Gendre, Anne-françoise.
C'est dans la zone littorale, les baies, les rades et les estuaires plus spécialement, que se repercute le plus d'impact des activités humaines sur le domaine marin. La zone littorale est le lieu de rencontre entre les effluents terrestres : charges polluantes agricoles, industrielles et urbaines, et les polluants provenant du large : produits du dégazage pétrolier notamment. L'originalité de l'écosystème littoral par rapport à l'écosystème océanique en général réside dans la prééminence du domaine benthique sur le domaine pélagique d'une part, et dans la prééminence du domaine rocheux sur le domaine sableux d'autre part, pour ce qui concerne la production primaire.

The breeding and cultivation of marine fish species for mariculture
Provedor de dados: 5
Autores: Nash, Colin E.
The culture of the marine fish has not made as much progress as other species in aquaculture, for example the marine and freshwater prawns. The large number of red seabream released each year by the Japanese into the Seto Inland Sea constitutes one of the major mari­ne fish projects, but the economic benefit for this type of ocean ranching is uncertain, and the cost of the fry is high. Dover sole and turbot still offer good potential for marine fish culture in Euro­pean and Mediterranean waters, but many of the farming techniques have been developed for the less valuable but more easily produced plaice. The grey mullet has increasing farm potential but its commercial markets are limi­ted as it has low value. It is more important as a subsistence...

Autores: Landrein, Sonia.
The determination of Mediterranean Salmonidae has been possible because of morphological and morphometrical studies and immunological and biochemical methods. It is evident that the 'sea trouts' belong to the species S. trutta fario and S. gairdneri irideus. These trouts have been acclimatized naturally to marine life. Experimental tests were undertaken in the laboratory, then in natural medium, to study the possibilities of trout acclimatization in sea water. They have confirmed the great adaptation qualities of these fishes to often extreme conditions. In the experiments undertaken in variable conditions, the influence of temperature and oxygen were exactly specified. Following these experiments, and other experiments realized in France and in other...

About twenty different prepared diets are given to young sea-basses weighing from 400 mg to a few grams, in 3 experiments, during which the growth and survival of the fish are regularly checked. The protein requirements of the species range around 47-SO % of the diet, and the energetic requirements seem to the covered by 11 to 12 % fat. The diets are mainly composed of fish meal. However fish autolysates and yeasts seem to give interesting results when incorporated into the diet.

Analyse et estimation des puissances de pêche
Provedor de dados: 5
Autores: Laurec, Alain.
An analysis of the fishing power concepts leads to a distinction between local fishing power (at a given location). and overall fishing power. Overall fishing power takes into account the ability to detect and quickly exploit rich areas. In order to estimate local fishing power it is necessary to compare the catches of different ships operating in neighbouring areas. Such a comparison performed on two ships will give an estimate of their relative fishing powers. The closer the two ships are, the more reliable will be the estimate. A weighting function must be used, and this function is related to the spatial heterogeneity of the fish density. Such a function is provided by the variogram as defined by Matheron (1965).

Culture of algae for feeding larval and juvenile molluscs in controlled aquaculture
Provedor de dados: 5
Autores: Ukeles, Ravenna.
The commercial controlled aquaculture of molluscs requires that simple inexpensive techniques be available for the large-scale culture of unicellular algal foods. Larval and juvenile stages consume large quantities of specific species of unicellular algae as a source of nutrition. Methods of culturing these food sources at the Milford Laboratory and elsewhere are discussed. Recent work that is directed at assisting hatcheries with programs of controlled algal culture is presented. The two areas of experimentation are : (1) the cryopreservation of axenic algal strains by freezing in liquid nitrogen for long-term storage, and (2) the culture of algae in a seawater medium with low levels of phosphate, nitrate and vitamin enrichment to effect a cost reduction...

Autores: Aquacop, Aquacop.
First important problems in pathology at the Centre Océanologique du Pacifique (COP) have been met during larval rearings of penaeid shrimps and Hacrobrachium rosenbergii. In penaeids, heavy mortalities  during the zoea and mysis stages have led to the diagnosis of two main types of diseases: a bacterial necrosis of the appendages and a fungus disease. Two preventive treatments with antibiotics during the zoea stages and a continuous treatment with a selective herbicide (Treflan) allow a consistent production of 100 post-larvae/liter (80% survival from the nauplius stage). With Macrobrachium rosenbergii, during the larval rearing, mortalities of bacterial origin have been recorded in some experiments. The observation of appendage necrosis allows early...

Provedor de dados: 5

We propose a series of paleogeographic maps of the western alpine system, from Triassic to Present, based on the geologic structure and evolution of the mediterranean,its adjacent folded belts and the associated basins, and on the evolution of the North Atlantic ocean according to the magnetic anomaly informations. The kinematic framework is relatively precise for the Cenozoic but the accuracy is quite poorer for the Mesozoic.Between Triassic and Upper Cretaceous,the reconstructed continental margins can be compared to present passive or active margins.The geologic evolution can be described in terms of plate tectonics. After Upper Cretaceous, the oceanic areas are quite limited and the geologic evolution is dominated by the continental collision...

Le métabolisme du magnésium chez cancer irroratus (say, 1817) (crustacé décapode)
Provedor de dados: 5
Autores: M.martin, Jean-louis.
Magnesium is, in Cancer irroratus, present in all tissues and organs analysed in our study.This metal is slightly concentrated by the organism.Only the exoskeleton possesses, during the whole intermolt cycle a concentration factor, with regard to sea water, higher than 1.For all tissues and organs, except the exoskeleton, the highest rates are observed during the stages A and B.These high concentrations are the consequence of the strong absorption of sea water by the crab which occurs during the molt and during the stages following the molt.In the whol crab, magnesium of constitution is quantitatively preponderant with regard to magnesium intervening in the osmoregulatory and enzymatic process. In the muscles, the rates of magnesium are low and constant...

Étude des effets d'effluents de fabrication de dioxyde de titane sur le développement larvaire d'un crustacé décapode : Palaemon serratus (PENNANT)
Provedor de dados: 5
Autores: Lassus, Patrick; Maggi, Pierre.
Le travail relaté ci-après a débuté en 1973. La partie expérimentale a duré 327 jours et a dû être intercalée entre les autres travaux en cours dans le laboratoire. De plus, elle nécessita pour chaque expérimentation l'obtention de femelles de crevettes graînées. D'où les délais qui nous ont été nécessaires pour publier ces résultats. Nous nous étions proposé de rechercher les éventuelles actions, de l'acidité et de la charge en fer de trois effluents, sur le développement larvaire d'un Crustacé. Nous avons expérimenté sur chacun des effluents en utilisant celui dont nous disposions au moment de l'expérimentation sans chercher à refaire des essais rigoureusement identiques sur les trois,vu les similitudes qui permettent une certaine extrapolation.

Relations entre le développement d'un phycomycète et l'accumulation de fer sur la surface branchiale de carcinus maenas (crustacé décapode) au cours du cycle d'intermue
Provedor de dados: 5
Autores: Martin, Jean-louis.
The structure of the branchial surface of Carcinus maenas (Crustacea, decapoda) shows variations during the intermoult cycle. These variations which involve a growing complexity are in close connection with the development of a saprophytic Phycomycete on the branchial lamellae. Filamentous hyphae of the Phycomycete, which take form after exuviation form, at stage C4 of the intermoult cycle, a very thin network which acts like a filter against the particles in the sea water flowing through the branchial chambers. Such a complexity is not observed in Homarus americanus. The branchial surface at stage C4 of the intermoult cycle shows a very uniform appearance. Filamentous hyphae observed in Carcinus maenas do not take form in Homarus americanus. [NOT...

Etude sedimentologique du plateau continental de la Guyane francaise.
Provedor de dados: 5
Autores: Moguedet, Gérard.
From a sedimentological point of view, the continental shelf of the French Guyana can be divided in three parts, parallel to the littoral: (1) the coastal zone where a very fluid mud is found; (2) a large band of sands which covers the rest of the continental shelf; (3) the zone of pelagic muds which corresponds to the lower part of the continental slope. The passage between the sands of the shelf and the littoral or pelagic muds is obtained by the intermediary of the muddy sands.

Micro-organismes de type Rickettsien chez les huîtres Crassostrea gigas Th. et Ostrea edulis L.
Provedor de dados: 5
Autores: Comps, Michel; Tige, Gilbert; Duthoit, Jean-louis; Grizel, Henri.
Some rickettsian infections have been found in French Atlantic oysters, Crassostrea gigas and Ostrea edulis. The micro-organisms parasite the digestive diverticulum epithelium cells although not creating any damage that could strongly affect the molluscs. If not for its shape, which appears to be longer in the case of the Crassostrea gigas Rickettsia, the characteristics of these two micro-organisms seem pretty close and enabled their inclusion in the Rickettsial order.

Evidence de la cristallisation fractionnée au niveau d'une ride médio-océanique: co, ni, cr, famous, leg 37 du dsdp
Provedor de dados: 5
Autores: Bougault, Henri.
The concentrations of high partition coefficient elements Co, Ni, Cr do not Vary or Vary little in the solid phase and the liquid phase as partial melting proceeds.For nickel and cobalt concentrations do not depend on the nature of the solid and the model of partial melting chosen. Quantitatively, the calculated value of the concentrations of these elememts in the liquid agrees with the concentrations found for undifferentiated tholeiitic samples.In so far, large variations of chromium and nickel found in oceanic tholeiites evidence the fractional crystallization process. Cobalt on one hand, nickel and chromium on the other give constraint in regard of the proportions of principal minerals crystallizing. [NOT CONTROLLED OCR]

Le travail sur le site des Iles CHAUSEY fait partie des six études confiées au CNEXO par le Ministère de l'Environnement. Les six études sont destinées à dégager l'ensemble des problèmes d'ordre écologique, économique et social qui pourraient se poser lors de la création de parcs ou de réserves naturelles en milieu marin. Les six études sont méthodologiques et ne sont donc pas préliminaires à la création de parcs marins sur les sites en question qui n'ont été choisis par le Ministère de l'Environnement que pour leur diversité. Si il était décidé de constituer à CHAUSEY un parc naturel en milieu marin en complément du parc terrestre envisagé, il serait indispensable de réaliser de véritables études de projet au cours desquelles seraient consultées toutes...

Observations relatives à l'infestation de Crassostrea gigas Thunberg par le copépode parasite Mytilicola orientalis Mori dans le Bassin d'Arcachon
Provedor de dados: 5
Autores: His, Edouard.
Le copépode parasite Mytilicola orientalis Mori (1935) a été rencontré pour la première fois dans le tractus digestif des C. gigas du Bassin d'Arcachon en mars1977. Au printemps, les taux d'infestation variaient de 10 à 40% sur l'ensemble de la baie. Tous les individus de tous âges (y compris le naissain capté en 1976) sont infestés. Dans un cas particulier, l'infestation s'accompagne d'une diminution de l'index de condition. Les mortalités qui se manifestent actuellement sont-elles imputables à l'action du parasite? Certains sujets infestés abritent plus de 20 copépodes.

Conservation par fumage de quelques poissons guyanais de lagune (Siluridés)
Provedor de dados: 5
Autores: Durand, Henri.
Experiments were carried out on two species of marine Silurides (Arius luniscutis and Arius albicans) to investigate the preparation of salted and smoked flllets. These fish are popular in the area and are smoked traditionally but an improved product is required. The fish were fIlletted, lightly brined and hot smoked (40 minutes at 35°C, 40 minutes at 70°C and 50 minutes at 85°C) in a mechanical kiln. The yield aftersmoking was estimatedand the products were vacuum wrapped and stored at 2-4°C. Quality changes were determined during storage by organoleptic and chemical means and the fillets were found to have an acceptable shelf life of 3 weeks. The paper concludes by considering the possibility of establishing a small industry based upon this new. product.

Elevage larvaire et production de naissain de Crassostrea gigas en milieu tropical
Provedor de dados: 5
Autores: AQUACOP.
In order to develop oysters culture in the South Pacific Islands and especially in French Polynesia, trials for producing spats of C. gigas in controlled conditions were conducted at the Centre Oaéanologique du Pacifique of the CNEXO in Tahiti. Tropical water environment (high temperature all year round and low productivity) led to the development of particular technics fir maintaining the brood stock. During the larval rearing a locally isolated algae strain is used and antibiotics as preventive treatments are added. For settling, crushed shell is used giving free spat. This paper presents and discusses the results obtained in the experimental hatchery during four rearing series from September to November 1976, when about 250 000 spats were produced. The...

Lijst van de in Nederland voorkomende Levermossen
Provedor de dados: 16
Autores: Gradstein, S.R.
The new checklist of Dutch liverworts comprises 126 species, 1 subspecies and 5 varieties. Since 1962 seven liverwort species have been added to the flora: Barbilophozia hatcheri, Calypogeia muellerana, Cephalozia pleniceps, Fossombronia incurva, Haplomitrium hookeri, Lophozia perssonii and Plagiochila porelloides. Of twelve species presumed occurrence in the Netherlands needs verification. Nomenclature follows Grolle’s “Verzeichnis der Lebermoose Europas” (Feddes Repert. 87: 171-279. 1976), except for Isopaches, Leiocolea and Microlejeunea, which are maintained as genera and Phaeoceros carolinianus, Cephalozia lammersiana, Chiloscyphus pallescens, Lophozia silvicola and Lophocolea cuspidata. , which are treated as intraspecific taxa.

Peter Arnold Florschütz (1923-1976)
Provedor de dados: 16
Autores: Greene, Stanley W.; Stafleu, Frans A.
The death of Peter Florschütz, on 27 May 1976, deprived the world of bryology of another of its spiritual leaders. Having fully regained scientific momentum after a period of managerial and organisational involvements connected with the changes in Dutch University life which occurred in the late sixties and early seventies, Florschütz had succeeded in starting a promising school of Utrecht cryptogamists, when, almost abruptly, death ended what would have become his scientific fulfilment. Peter Arnold Florschütz was born in the Hague on 16 March 1923. His father, Gaspard Florschütz, was a chief inspector of the Hague city police and his mother was Elizabeth Philippina Engelina Scharwachter. He is survived by his mother, his wife, his three children and two...

A new species of Thaumamannia from Surinam (Heteroptera, Tingidae, Vianaidinae)
Provedor de dados: 16
Autores: Doesburg, P.H. van.
During soil fauna investigations performed in 1959 by Dr. J. van der Drift (see his study, 1963), three specimens were collected of a small coleopteroid heteropteron, representing a new species belonging to the genus Thaumamannia Drake &amp; Davis, 1960. Up till now, only one other species in this genus was known, viz., T. manni, collected in an ants' nest by Mr. W. H. Mann in Bolivia. The other three known species in the subfamily Vianaidinae1) belong to the genus Anommatocoris China, 1945, and are also found with ants (Drake &amp; Ruhoff, 1965). The new species described here is closely related to the Bolivian species, and in all likelihood is also myrmecophilous. It is the first record of a vianaidine tingid for Surinam and for the Guyana's. The...

Rearrangement of certain Glyphipterygidae sensu Meyrick, 1913, with descriptions of new taxa (Lepidoptera)
Provedor de dados: 16
Autores: Diakonoff, A.
In 1913, Edward Meyrick removed several genera from his compound family Yponomeutidae and united them in a new group, "Glyphipterygidae". After 1954, this name has been used generally, often in the emended spelling "Glyphipterigidae". The family name was not new but used by Meyrick in an entirely different sense. Former authors (Zeller, 1839; Stainton, 1854; Frey, 1856, etc.) indicated with the name "Glyphipterygidae" only one of the two main groups of Meyrick's enlarged concept, viz., the "Glyphipteryginae" or the "Glyphipterygidae sensu stricto".  In spite of its existence during quite a long time, Meyrick's family " Glyphiteryginae" proved to be an unsatisfactory combination. In later years, especially recently, its highly heterogeneous character became...

Die Strukturen der Basidiosporenwand und des Apikulus, und deren Beziehung zur Exogenisation der Spore
Provedor de dados: 16
Autores: Clémençon, H.
In an attempt to find the basic architecture underlying the known structures of the basidiospore walls some developmental patterns of the formation and reduction of the wall teguments are described. Spore walls are built from two classes of substances differing in their aspect in the electron microscope: an electron dense material and an electron transparent material. These two classes, by mixing and separation, form two classes of teguments, the eusporium and the myxosporium. The teguments are modified by differentiation and reduction processes. A processus called exogenisation leads from an endospore to a false exospore and eventually to a true exospore. A false exospore is morphologically an endospore but functionally an exospore. The wall of the...

A revision of the megacanthoxea-bearing tetillids (Porifera, Spirophorida), with a description of a new species
Provedor de dados: 16
Autores: Soest, R.W.M. van.
A sponge collection dredged by Dr. P. WAGENAAR HUMMELINCK in the vicinity of Barbados (West Indies) contained a Cinachyralike specimen bearing large and conspicuous acanthoxea. This find induced the present author to re-examine all specimens with similar spiculation reported so far. A review of the literature revealed that a total of three such specimens has been described in two different genera, all as separate species, viz. Acanthotetilla hemisphaerica Burton, 1959, Acanthocinachyra enigmatica Levi, 1964, and Acanthocinachyra seychellensis Thomas, 1973. Both genera are reported to differ in the presence (genus Acanthocinachyra) or absence (genus Acanthotetilla) of sigmaspire microscleres. In view of the close similarity of the two genera it seemed wise...

Tristania R. Brown, Aiton’s Hortus Kewensis (2nd Ed.) 4 (1812) 417, was established with three species — T. neriifolia, T. laurina, and T. conferta. A number of other species have since been added to the genus and a recent study (Wilson, 1971) has shown that the three original species belong to three different groups and further that these groups are sufficiently different to warrant their separation at the generic level. All of the New Caledonian species belong to the Tristania laurina group. It has not yet been decided which of the groups should retain the original generic name, but if the T. laurina group is not selected the name Tristaniopsis Brongniart et Gris, Bull. Soc. Bot.

Note on Arrhenechthites haplogyna (Asteraceae)
Provedor de dados: 16
Autores: Royen, P. van.
Arrhenechthites haplogyna (F. Mueller) Mattfeld was originally described as Senecio haplogynus F. Mueller (Trans. Roy. Soc. Victoria 1, 1899: 14), based on rather poor material collected by Sir William MacGregor from Mount Knutsford. Von Mueller remarks that the species could be placed both in Senecio or Erechthites, basing himself on the statement by Bentham and Hooker in the Genera Plantarum 2 (1873) 208, ‘that occasionally some solely pistillate flowers occur in species of Senecio, hence the only characteristic which separates Erechthites from Senecio, is unreliable, and therefore the present plant may be placed in either genus’. Mattfeld (Bot. Jahrb. 69, 1938: 292) creates a new genus, Arrhenechthites, and moves Senecio haplogynus into this genus,...

Vaillantellinae, A New Subfamily Of Cobitidae (Pisces, Cypriniformes)
Provedor de dados: 16
Autores: Nalbant, T.T.; Banarescu, P.M.
INTRODUCTION It is generally accepted that the Eurasian freshwater fish family Cobitidae includes three main divisions, usually considered as subfamilies: Cobitinae, Botiinae and Noemacheilinae (Berg, 1940; Ramaswami, 1953; Nalbant, 1963). The two first named, in which the lateral ethmoids are movable, are usually considered closer to each other than either of them to the Noemacheilinae. The largest subfamily is Noemacheilinae; some 180 species are presently accepted as valid, most of them being still ascribed to a single genus, Noemacheilus. Quite a few other genera are accepted besides Noemacheilus, one of these being Vaillantella Fowler, 1905. Its original description (Fowler, 1905, in a footnote) is quite short, mentioning only the very long dorsal...

What a botanist can contribute to conservation in Malesia
Provedor de dados: 16
Autores: Jacobs, M.
Reviewing the conservation situation in Indonesia, we see that concern for animals outweighs that for plants. Sumatra with its richer fauna of large mammals, is better cared for than Borneo with its richer flora*. Too often in the reports, a forest is called a forest, to the neglect of the amazing diversity among the lowland primary rain forests. The absence of botanical expertise beyond the surface is evident throughout, and but occasionally regretted. In view of the great species diversity, and of the fact that this is located in primary vegetations, for animals of nearly all groups as well as for plants, plant conservation clearly comprises at least half the conservationist’s job, in a humid tropical forest region like Malesia. A botanist’s contribution...

The Gammarus pulex-group in Italy (Crustacea, Amphipoda) (A study based on material from the Museo Civico di Storia Naturale, Verona)
Provedor de dados: 16
Autores: Goedmakers, Annemarie; Pinkster, Sjouk.
A historical review is given of the literature oil Italian members of the genus Gammarus. Only three Gammarus species were known with certainty from Italy, viz G. fossarum Koch, 1836, G. lacustris G.O. Sars, 1863, and G. cf. balcanicus Schäferna, 1922. G. fossarum is widely distributed in the northern part of Italy. Near the Yugoslavian border a member of the G. balcanicus-group sometimes coexists with this species. G. lacustris seems to be confined to mountain lakes. Some doubt remains about the identity of G. fontinalis A. Costa, 1883. During the present study a new species was found, G. italicus, inhabiting a restricted area in the central part of Italy and the northwestern part of Sardinia.

INTRODUCTION Recently, material representing an undescribed species of the genus Argeia Dana in the western Atlantic, the first record of that genus from this ocean, became available to me. The previous records of Argeia are of 4 species in the Pacific, including one whose range extends around the entire northern Pacific, and one from the Indian Ocean. Two of the species, though, represented systematic problems which it was necessary to resolve. At the same time, 4 other genera, Parargeia Hansen, Bopyrosa Nierstrasz &amp; Brender à Brandis, Stegoalpheon Chopra and Argeiopsis Kensley, are clearly related to Argeia, but it has been difficult to assign any of them to currently recognized bopyrid subfamilies.

INTRODUCTION Van Bruggen (1974) discussed the identity of specimens of the North American pulmonate genus Helisoma Swainson, 1840 (Mollusca: Planorbidae) from three localities in southern Africa. He identified Helisoma (Seminolina) cf. duryi seminole Pilsbry, 1934, from a farm dam in South West Africa and Helisoma (?Pierosoma) sp. from an artificial pond at Mandini in Zululand (recorded as Helisoma sp. by Brown, 1967) and from Cape Point on the Cape Peninsula. These identifications were based on shell characters since only dry material was available. Snails belonging to Helisoma have been collected by the present author from two additional localities and are examined below.

Ökologie der Moose der Gletscherinsel Isla Persa (Berina, Schweiz) (Moose der Alpinstufe)
Provedor de dados: 16
Autores: Oostendorp-Bourgonjon, Cora.
Auf Isla Persa, einer Gletscherinsel auf 2450-2850 m Höhe in der Süd-Ost-Schweiz (Berninagebiet), wurden im Sommer 1973 und 1974 floristische und ökologische Untersuchungen vorgenommen. Es wurden 114 Moosarten auf der Insel gefunden. Ausführliche Standortsdaten werden für jede Art gesondert gegeben. Zugleich wurden 7 verschiedene ökologische Nischen unterschieden, und zwar 5 Nischen mit wenig Arten und 2 Nischen mit vielen Arten. In den erstgenannten Nischen finden wir extreme Standorte, wie schnell fliessendes Wasser von Schmelzwasserbächen, exponierten Fels und sandig-lehmige Alluvionen. In den letztgenannten Nischen finden wir geschützte Stellen mit gut entwickeltem Boden. In diesen Nischen kommen einige Arten vor, die aus der Literatur nur von...

Electron microscopic study of Conidium ontogeny in Coniothyrium cupressacearum (Coelomycetes)
Provedor de dados: 16
Autores: Reisinger, Otto; Morelet, Michel; Kiffer, Etienne.
Coniothyrium cupressacearum (Morelet) Morelet, exhibiting annellated conidiogenous cells in light microscopy, was examined by transmission electron microscopy. Since the conidial wall is formed de novo, i.e. not continuous with a pre-existent layer of the conidiogenous cell wall, the conidiogenesis is clearly phialidic. After production of a number of conidia, a percurrent proliferation of the phialide collar occurs; this explains the annellated appearance. The annellide is not considered to be a special kind of conidiogenous cell but a variation of either the phialide or the aleuriophore.

The Zoogeography of the crustacean suborder Ingolfiellidea, with descriptions of new West Indian taxa
Provedor de dados: 16
Autores: Stock, Jan H.
In a previous paper (STOCK, 1976b) I described, after a fortuitous find of a single specimen, an Ingolfiellid from a brackish well in Bonaire under the name of Ingolfiella (Gevgeliella) putealis. Financial support of the “Treub Maatschappij” (Utrecht) permitted me to revisit Bonaire in June 1976. At this occasion, a rich additional material of I. (G.) putealis could be collected in several brackish wells on the island; moreover, samples from a freshwater spring in Bonaire and from a marine interstitial habitat in Curaçao yielded Ingolfiellids as well, which proved to belong to undescribed species. This brings the total number of species known from the West Indies to three. Thanks are due to Mr. P. HOETJES and Mr. E. WESTINGA, for attempts to collect...

INTRODUCTION At the request of Dr. Dennis M. Devaney, Invertebrate Zoologist, Bernice P. Bishop Museum, Honolulu, Hawaii, I investigated a number of Polynesian soft corals kept in the Museum mentioned. At the same time Professor Paul J. Scheuer, University of Hawaii at Manoa, Department of Chemistry, Honolulu, Hawaii, asked me to identify some octocorals from Enewetak Atoll (Marshall Is.) and from Ponape Island (Carolines). These collections include several well-known species which are not described in the present paper. I only mention their names with the localities added in parentheses: Cladiella pachyclados (Klunzinger, 1877) (American Samoa); Lobophytum borbonicum (Von Marenzeller, 1886) (Enewetak); Lobophytum pauciflorum (Ehrenberg, 1834) (Enewetak,...

Two new spiders from Sumatra (Araneae, Telemidae and Ochyroceratidae)
Provedor de dados: 16
Autores: Brignoli, P.M.
Apneumonella jacobsoni n. sp. is described (♀, ♂ unknown; typ. loc.: Fort de Kock, Sumatra, Indonesia); this species, which can be distinguished from all other known Telemids by general morphology, genitalia, chelicerae, etc., is provisionally included in Apneumonella; the differential characters between the existing genera of the Telemidae are apparently small, mostly through lack of information, and only future study may allow to decide on their validity and on the position of this and other species. Speocera krikkeni n. sp. is described (♂ ♀; typ. loc.: Indonesia, N. Sumatra, Mt. Bandahara, Serbolangit Range); the only closely related species seems to be S. laureata Komatsu, 1974, from Okinawa, from which it can be distinguished by the ♂ ♀ genitalia.

The taxonomy and ecology of a new monocelid flatworm from Macquarie Island (Platyhelminthes, Turbellaria)
Provedor de dados: 16
Autores: Ball, Ian R.; Hay, David A.
Macquarie Island (54°37'S 158°54'E) has been investigated for the occurrence of freshwater macroturbellarians. Twenty sites were examined but only one species, here ascribed to the genus Minona sensu lato of the Monocelididae, was found and it is described as Minona amnica sp. nov. Its closest taxonomic relationships seem to be with M. istanbulensis Ax from the Black Sea, and M. mica Marcus from Brasil. The new species is unusual in that it occurs throughout the fresh waters of the island even though it is a member of a predominantly marine group. Minona amnica occurs from windswept plateau lakes down to brackish water near the sea and data concerning the distribution and relative abundance of the species in various habitats are presented and discussed.

The distribution and status of the rhinoceros, Dicerorhinus sumatrensis, in Borneo — a review
Provedor de dados: 16
Autores: Rookmaaker, L.C.
In the second half of the 19th century, the rhinoceros occurred throughout Borneo except southern Sarawak, northwestern Kalimantan and some parts of southern Kalimantan. The animal was extinct in the coastal and other populated areas in about 1930, especially in the southern part of Kalimantan. Presently some small populations remain, scattered over the Sarawak interior (if the rhinoceros survives at all there), northeastern Sabah, possibly also southern Sabah and around Mt. Kinabalu, and the interior of Central and East Kalimantan. It is estimated that some 15 to 25 rhinos are still alive in Borneo.

Some remarks on Miogypsina (Miogypsina) socini Drooger, 1954 (Foraminifera) from northern Italy
Provedor de dados: 16
Autores: Bock, J.F. de.
In spite of the generally poor preservation of the specimens, it could be observed that in many specimens the large, often somewhat trochoid spiral out of PA-I, surrounding I and II, passes the small spiral out of PA-II without forming a closing chamber. In several specimens the vertical section shows that the embryonic-nepionic apparatus forms an angle with the equatorial plane. This makes it difficult to distinguish in a horizontal thin section a spiral chamber from an equatorial or lateral chamber. The sample used contained numerous microspheric specimens, which are markedly different from the megalospheric specimens both externally and internally. The difference between the subgenera Miogypsina and Miolepidocyclina is discussed.

Autores: Stock, Jan H.
The origin of the Antillean inland water fauna is discussed. It is assumed that the West Indian islands have been populated along three different lines: by dispersal, by divergence (fragmentation) and by stranding of marine elements during regression periods. – The phylogeny of the hadziid amphipods appears to correspond with the Regression Model. – The members of hadziid group are enumerated, the differences between the genera are tabulated and keyed. – The type-species of the genus Hadzia, H. fragilis, is re-examined. Hadzia taveresi is transferred to the new genus Metahadzia. – The genus Metaniphargus is re-surrected; its type-species M. curasavicus is re-described after topotypes and divided into two subspecies.

On the collecting and preparation of Utricularia specimens
Provedor de dados: 16
Autores: Taylor, P.
The taxonomic study of this genus is, and always has been, severely hampered by the almost universal incompleteness of the material available in the herbarium. The vast majority of herbarium specimens, at least of the terrestrial species which comprise some 70% of the genus, consist of inflorescences alone, i.e. without vegetative parts. The aquatic species fare little better and although specimens are often more complete they are usually badly prepared so that vital characters such as the specifically characteristic branching of the foliar organs is completely obscured. Furthermore, in view of the very delicate nature of both the floral and vegetative parts, especially the complex and often very small traps, drying is rarely as satisfactory as...

Consequently upon a revision of Mischocarpus (Van der Ham, 1977a), a detailed study has been made of several characters in Arytera in order to get a better understanding of the delimitation of the two genera mutually. The differences between Mischocarpus and Arytera given by Radlkofer (1931) in his key are vague and can only be used when fruiting material is available. However, several species in Arytera were described by him and others on flowering material only. Two species of Mischocarpus could be connected with species of Arytera. One species of Arytera appeared to be the same as Mischocarpus exangulatus. M. exangulatus has, besides typical Mischocarpus characters, several features unique in Mischocarpus but more regularly occurring in Arytera....

Geographical variation of Caprimulgus Macrurus Horsfield (Aves, Caprimulgidae)
Provedor de dados: 16
Autores: Mees, G.F.
INTRODUCTION The races of Caprimulgus macrurus Horsfield have been revised several times, most recently by Oberholser (1915). This work is now over sixty years old and it was exclusively based on the very inadequate material at the time available in North American collections, without any reference to the large series in the museums of London, Tring, Leiden, etc. As a result, much of Oberholser's revision is based on little more than guesswork (cf. Rothschild &amp; Hartert, 1918: 321). Also, Oberholser omitted the races belonging to the "manillensis" group, although several years earlier Hartert (1906) had concluded that they are conspecific with C. macrurus. My own work on the problem of the geographical variation of the species started over twelve years...

A Namurian brachiopod fauna from Meré (Province of Oviedo, Spain)
Provedor de dados: 16
Autores: Martínez Chacón, M.L.; Winkler Prins, C.F.
An interesting brachiopod fauna from Namurian (Marsdenian?) deposits — provisionally named the Meré beds herein — is described. The fauna contains seven new species: Drahanorhynchus cantabricus, Anopliopsis? parva, Caenanoplia martinezi, Tornquistia scutiformis, Aseptella asturica, Kitakamithyris merensis, and Plicotorynifer lamellosus; and one new genus: Aseptella with the type species A. asturica. The material of a new productellid and a new ambocoeliid was too poor to give them formal names. The special character of this fauna — only a much older fauna from the Chappel Limestone of Texas (U.S.A.) being closely comparable — indicates special environmental conditions: presumably a soft, muddy bottom. The brachiopod fauna indicates a Namurian, probably...

Studies on Opilioacarida (Arachnidea) : IV. The genera Panchaetes Naudo and Salfacarus gen. nov.
Provedor de dados: 16
Autores: Hammen, L. van der.
In the first three parts of the present series (Van der Hammen, 1966, 1968, 1969) I have dealt with four species of Opilioacarida, viz., Opilioacarus texanus (Chamberlin &amp; Mulaik), Paracarus hexophthalmus (Redikorzev), Opilioacarus platensis (Silvestri), and Adanacarus arabicus (With). The detailed redescription of Opilioacarus texanus (the first part of the series) constituted the morphological base for the subsequent studies. In the meantime, I completed a glossary of opilioacarid terminology (Van der Hammen, 1976), in which not only terminology, but also notations, measurement, description and orientation of figures are standardized. Consequently the continuation of my series of studies on Opilioacarida is now based on the above-mentioned glossary....

Heathland vegetation in the Netherlands
Provedor de dados: 16
Autores: Smidt, J.T. de.
A syntaxonomic survey is given from the heathland communities in the Netherlands. The almost natural heathlands on coastal dunes belong to the Carici arenariae – Empetretum (Empetrion nigri) from dry or humid habitat and to the Empetro – Ericetum (Ericion tetralicis) from wet dune valleys. The antropogenous inland heaths belong to the Ericetum tetralicis (Ericion tetralicis) on wet peaty soils and to the Genisto – Callunetum and Vaccinio-Callunetum (Calluno-Genistion pilesoe) on humid to dry sandy soils. The latter association is confined to hilly districts with high precipitation. Ten new subassociations are described.

Every new mammal or bird in the Amsterdam zoo, without exception, is kept in quarantaine for some weeks and until necessary standard checks are done. The number of mammals in the collection during the period 1967-1973 varied between 729 and 858 belonging to 172 to 208 species. In birds these figures were 1571 and 1803 specimens of 391 to 520 species (table I). The average percentage of deaths in mammals was 12.4% (table II) and in birds 13% (table III). The causes of death (tables IV and V) are arranged under 15 headings for mammals and under 18 for birds; both numbers and percentages are given. During 1967, 1968, and 1969 there were many cases of Yersinia pseudotuberculosis in the nocturnal house. The troubles only stopped after vaccination of all animals...

The morphology and relationships of Paracryphia (Paracryphiaceae)
Provedor de dados: 16
Autores: Dickison, William C.; Baas, Pieter.
A comprehensive study of floral and vegetative anatomy of the monotypic New Caledonian genus Paracryphia Baker was initiated in an attempt to help clarify the evolutionary relationships of the genus. Detailed descriptions of leaf, axis, nodal, wood, floral, pollen, and fruit morphology and anatomy are presented. In general, most vegetative characters are distinctly primitive whereas those of the reproductive organs are regarded as advanced or specialized. The present study confirms the opinion that Paracryphia merits familial status. All previously suggested relationships of the genus are rejected in favor of a view that envisions Paracryphia as an independent and early divergence from the Thealean, Ericalean, and/or Celastralean lines of evolution.

Autores: Gittenberger, E.; Manga, M.Y.
Many samples of Helicellinae have been collected by the second author in León, a province in the North of Spain. While trying to identify the species represented in this material, not only the most recent summarizing publications on Spanish Helicellinae by Ortiz de Zárate (1943, 1946, 1950, 1962 1964) were consulted, but the older literature was studied as well, especially the books of Locard (1899) and Servain (1880). These, however, constitute a most serious barrier towards a better knowledge of the Iberian terrestrial molluscan fauna, as of the great number of alleged new species described in them, only unclear shell descriptions are provided, not accompanied by a single figure. Several of our species from León are considered to be new. These are...

The tree-climbing crabs of Trinidad
Provedor de dados: 16
Autores: Hagen, Heinrich-Otto von.
An annotated list of the brachyuran (12) and anomuran (1) tree-climbing crabs of Trinidad (West Indies) is presented (see Table 1 for species names). Some of the species mentioned (e.g. Aratus pisonii, Goniopsis cruentata) are well-known treeclimbers, in others (e.g. Sesarma roberti, S. ricordi) this peculiar behaviour is recorded for the first time. Some data on the diet and the locomotion of climbing Grapsidae are given. Aratus was found to feed mainly on algae and decayed wood, not on mangrove leaves. A synopsis of pertinent data from literature (Table 2) yielded 30 further species names of tree-climbing crabs. Like in Trinidad, most of these belong to systematic groups comprising many or only semiterrestrial species. The trees ascended are mangroves in...

Pollenmorphology of the genus Mischocarpus (Sapindaceae)
Provedor de dados: 16
Autores: Ham, R.W.J.M. van der.
The pollen morphology of all 11 species of the genus Mischocarpus is studied. All species possess basically the same syntricolpate pollen type. Transitions to the tricolpate type were observed rarely. Within the syntricolpate type, subtypes could be established. For a few species a rather wide range of variability in some characters is described. Pollen morphology correlates with macromorphology as well as with geography, thus supporting the results, based on macromorphological evidence, concerning infrageneric structure and relationships of Mischocarpus.

A selection of well developed apatite crystals of different habit and colour, originating from the tungsten-tin deposits of Panasqueira in Portugal, were analyzed by means of non-destructive optical methods. Phenomena of pleochroism, absorption and luminescence line-spectra, broadband-spectra and phosphorescence were studied. On the basis of extensive and systematic data, obtained from more than sevenhundred polarized spectrophotograms, registered of about seventy apatites from different types of deposit, and of a whole range of fluorapatites, doped with lanthanides and transition elements, it was possible to define the particular type of crystalfield and the nature and quantity of a number of trace elements, present in the fluorapatite from Panasqueira....

Therefore the present material consists mainly of common reef-dwellers; however, a few were collected by dredging.

The nomenclature of Delpya (Sapindaceae)
Provedor de dados: 16
Autores: Leenhouts, P.W.
The name Delpya, with the specific epithet muricata, was used for the first time in 1895 by Pierre under plate 328 of his ‘Flore forestière de la Cochitichine’ (in honour of his draughtsman E. Delpy, who was the illustrator of that flora). The generic name was invalid, however, as in the accompanying text it is mentioned as a synonym under Paranephelium muricatum, the name under which the species is described. In 1910 Radlkofer validated the name Delpya, but made it illegitimate by reducing the name Sisyrolepis, validly described by himself in 1905, to it. Since then, the illegitimate name Delpya has always been used. The synonymy of the genus and of the only species recognized under it, as far as known to me, is as follows: SISYROLEPIS Sisyrolepis Radlk....

Autores: Stelt, A. van der; Mos, W.; Diegenbach, P.C.
Since the description of a helicoidal pattern of muscle fibres in teleost fishes by Van der Stelt (1968), Alexander (1969) stated that there are two basic patterns. One is found in selachians and primitive bony fishes as Anguilla and Salmo, whereas it is also found in the caudal peduncles of teleosts, which are considered more advanced. More anteriad a quite different pattern is found, resembling the helicoidal pattern. The elucidation of this pattern was disclosed by both Van der Stelt (1968) and Alexander (1969) by reconstruction from horizontal, as well as vertical serial sections. Van Raamsdonk et al. (1974), in a study of the early development of the myomeres of Brachydanio rerio, observed a transition of a primary longitudinal course of muscle cells...

Pistia stratiotes L. toch ook in 1975 gevonden. Ir. D.

Note on the occurrence of Acanthocephala larvae in gammaridean Amphipoda from the river Slack (France, Dépt. Pas-de-Calais)
Provedor de dados: 16
Autores: Maren, Marion J. van.
In gammaridean Amphipoda from the river Slack in northern France larval stages of two Acanthocephala species have been found. In Gammarus fossarum larvae of Polymorphus minutus, a parasite of waterfowl, occurred. This worm was found only once in Echinogammarus berilloni. Larvae of Metechinorhynchus truttae, parasitizing fish, were harboured only by E. berilloni and have not been encountered in Gammarus fossarum during the present investigations.

Provedor de dados: 16
Autores: Mennega, Alberta M.W.; Lanzing-Vinkenborg, Marijke.
The structure of the wood of the genera Castilla, Helicostylis, Maquira, Naucleopsis, Olmedia, Perebea and Pseudolmedia, considered to belong in the Olmedieae (cf. Berg 1972) is described. The diversity in anatomical structure between the genera is small, and it is hard to distinguish Maquira, Perebea and Pseudolmedia from each other. Castilla can be recognized by its thinwalled and wide-lumined fibres, Helicostylis by its parenchyma distribution, Naucleopsis (usually) by its more numerous vessels with a smaller diameter. A more marked difference is shown by the monotypic genus Olmedia with apotracheal banded parenchyma instead of the paratracheal aliform to confluent-banded parenchyma of the other genera. Septate fibres, which are characteristic for the...

J. in den Bosch (Leiden) tijdens een autorit in een vochtige wegkant een Lycopodium-soort, die hij niet kon thuisbrengen. Toen een determinatie op het Rijksherbarium uitwees, dat de wolfsklauw L. cernuum L. var. pungens (v. A. v. R.) Adelbert bleek te zijn, had de vinder enige tijd nodig om zich te realiseren, waar precies hij deze vondst gedaan had. Uiteindelijk bleek dit de Posbank bij Arnhem te zijn geweest. L. cernuum var. pungens is een tropische plant, die wel in bloemstukjes wordt gebruikt. De veronderstelling lijkt gewettigd, dat deze vondst uit een dergelijk, al dan niet weggeworpen bloemstukje afkomstig zal zijn.

Een nieuwe vindplaats van Campanula latifolia L.; een inheemse soort?
Provedor de dados: 16
Autores: Sykora, K.V.; Westhoff, V.
The authors report a new locality in the Netherlands (Zeeland) in which Campanula latifolia L. has been found. A description of the vegetation of the site is given and the habitat is compared with the environments in which this species occurs in other countries of Europe. A map of the distributional area was drawn according to the floras of the European countries. So far, the species has been found several times in the Netherlands, but botanists considered such occurrences as incidental escapes (cultivated plants running wild). The data about Dutch localities are analysed and it is demonstrated that the presumption (by the collector or by later interpreters) that the species on the locality would be running wild, in a number of cases does not hold.

A new and primitive retrobursal planarian from Australian fresh waters (Platyhelminthes, Turbellaria, Tricladida)
Provedor de dados: 16
Autores: Ball, Ian R.
A primitive freshwater planarian, Eviella hynesae gen. et sp. nov. is described from Australia. It is characterized by its lack of eyes and pigment, possession of caudally branched oviducts, and fully fused testes. Although a primary bursa is absent, its function being taken over by the modified female genital canal, the female copulatory system is posterior to the male system. Despite this maricolan feature, and other similarities with primitive southern hemisphere freshwater planarians that have been classified in the Maricola, the present species is placed in the family Dugesiidae of the Paludicola. Evidence from its sensory organs suggests that it belongs on the main evolutionary line from which the majority of Australasian freshwater planarians have...

Sedentary ciliates from two Dutch freshwater Gammarus species
Provedor de dados: 16
Autores: Bierhof, M.J.; Roos, P.J.
The sedentary ciliate fauna living on the body surface of Gammarus tigrinus and G. pulex from Dutch freshwater habitats has been investigated. Fourty-seven ciliate species are found, of which 43 belong to the order Peritrichida, suborder Sessilina, 3 belong to the order Suctorida and 1 belongs to the order Chonotrichida. Two new species in the genera Intranstylum and Pseudocarchesium are described. It appears that there is a seasonal variation in the number of epizoic ciliates as well as in species composition. In general, the species with a contractile stalk are found on external, often fast-moving, body parts. Species with a noncontractile stalk seem to prefer more quiet and sheltered positions. After ecdysis there is a succession of the genera Epistylis...

Regeneration in the gorgonian Plexura flexuosa (Cnidaria, Octocorallia)
Provedor de dados: 16
Autores: Silveira, Fábio Lang da; Hof, Tom van ’t.
Regenerative capability of Plexaura flexuosa is investigated in experiments which simulate the injuries caused by predation of the ovulid snail Cyphoma gibbosum: partial or total removal of the coenenchyme from the axial skeleton. Regenerative growth of the coenenchyme is primarily induced by the possibility of linear extension of the axial epithelium; settlement of fleshy algae or e.g. Millepora (firecoral) on the axial skeleton inhibits the recovery of the coenenchyme. Coenenchyme growth is accompanied by evagination of the polyp cavity wall and by increased mesoglea production. The cellular basis for regeneration lies in the migration capability and morphogenetic plasticity of at least two cell types of the coenenchyme epidermis: interstitial cells and...

According to rough estimate, in these years one quarter of the hardwood in the international timber market comes from Dipterocarpaceae: keruing, meranti are the best-known names. It was a good idea to convene a conference for a review of the available knowledge on this family, which is best represented in Malesia with 380 species. Most of them occur in Borneo, Malaya, Sumatra and the Philippines, in that order. About 35 botanists – too few of them from the region itself – attended the 3-day session, on 14, 15, and 16 June 1977. Organizer was Mme. Géma Maury of Brunoy near Paris, whose work in Malaya on seedlings of the family was mentioned on pages 2565-2566 of the Flora Malesiana Bulletin. Host was Professor J.F.

Contribution to the knowledge of the nervous system in the tentacles of some coelenterates (Anemonia sulcata, Metridium senile, Cerianthus membranaceus, Tealia felina and Hydra vulgaris)
Provedor de dados: 16
Autores: Marle, J. van.
The nervous system in the tentacles of the sea anemones Tealia felina, Anemonia sulcata, Metridium senile and Cerianthus membranaceus was studied using light microscopic and electron microscopic techniques. Because of the small dimensions of the nerve cells (6—7 µm) and of the neurites (diameter &amp;lt; 1 µm) satisfactory information could not be obtained using conventional histological techniques. Electron microscopic investigation showed that the nervous system can be divided into three parts: the plexus round the mesogloea, a nervous system between the muscles (obviously connected with the plexus) and sensory cells in the outer layer of the tentacle connected to the plexus by nerve fibres. The latter nerve cells with their fibres are arranged radially...

An electron microscopical examination of the ageing process of the wing muscles of the House Fly (Musca domestica)
Provedor de dados: 16
Autores: Diegenbach, P.C.; Meijssen-de Ridder, E.
Morphometric analysis was carried out on wing muscles of the House Fly (Musca domestica), ranging from the pupation period to death. In the first week a clear increase was found in the percentage of food reserve consumed by the cell components. Both fibrils and sarcosomes increase in circumference during the first week. The sarcosomes then fuse. After the first week few changes occur. The sarcosomal volume increases in male flies. No disintegration or degeneration of the muscle cells appears with old age. Even the fact that the wing of the male flies exhibits abrasion earlier than that of females cannot be correlated with changes in the wing muscles. The ratio of fibrils to sarcosomes is greater than two to one. This ratio differs in males and females. A...

Autores: Hofstra, J.J.; Weeda, E.J.
In this paper a description is given of the vegetation in a pool near Hengelo (prov. of Overijssel). In the dry summers of 1975 and 1976, large parts of the shores and shallows of this pool ran dry. On these places a vegetation developed consisting mainly of Eleocharis acicularis, Elatine hexandra and to a lesser extent Juncus bulbosus. Presumably the first species is present permanently; it only flowers if its habitat runs dry. The annual Elatine hexandra was seen from July to as late as January. While in the course of summer and autumn the water level was sinking, Elatine died off in the upper zones and appeared in zones recently run dry. Somewhat later than the former two species, Juncus bulbosus developed. Whilst J. bulbosus is usually a perennial, in...

Provedor de dados: 16
Autores: Kits van Waveren, E.
Examination of four collections of Psathyrella frustulenta sensu A. H. Smith and four of P. frustulenta sensu Romagn. revealed that the former species is distinguished from the latter by its strongly developed veil and habitat (woods) and that there are considerable microscopic differences between the two (spore size, number and shape of pleurocystidia, pattern of cellular lining of gill edge). The former species is to be regarded as conspecific with Agaricus frustulentus Fries, the latter as conspecific with P. clivensis (Berk. &amp; Br.) P. D. Orton. It is argued that the name P. fibrillosa was misapplied by J. E. Lange and A. H. Smith to a species for which the name P. friesii is introduced.

Morphologie végétale et répartition des Mammifères
Provedor de dados: 16
Autores: Saint Girons, Marie-Charlotte.
In many studies on mammalian distribution, vegetation is considered in particular as a source of food and its importance in terms of habitat has been neglected. The type of vegetation cover is a limiting factor only in the choice of ecological niches but does not in general affect the overall distribution. On the contrary, the density of mammals is in many cases associated with the morphology of the plant cover, especially in the case of granivores (rodents), less for insectivores and small carnivores. In the paper several examples are given concerning mammals of Europe and North Africa and the importance of vegetation morphology for nests, cover and landmarks, as well as exceptions and adaptations, especially on islands.

A new classification of Chelicerata
Provedor de dados: 16
Autores: Hammen, L. van der.
Progress in classification of Chelicerata has been thwarted especially by two factors, viz., the concept of mites as one monophyletic group, and the opinion that this group consists of species with a highly modified plan of construction and without any trace of true segmentation. The only characters which are generally shared by all groups of mites refer to the presence of a gnathosoma (i.e. the cone-shaped, movable structure comprizing the mouthparts), and the occurrence of a larva with only three pairs of legs (the last-mentioned character is also found in Ricinulei). A comparative morphological study of the gnathosoma (Van der Hammen, 1970b, 1972) has, however, demonstrated that two fundamentally different types can be distinguished, which must be the...

Collaboration of taxonomists and draughtsmen
Provedor de dados: 16
Autores: Jacobs, M.
The preparation of botanical drawings is a craft in its own right, and furthermore, draughtsmen are human beings. Even these simple truths are trodden down by the taxonomist who during a final hour hands the draughtsman a bundle of specimens and some hasty indications. Naturally the result is anguish and confusion. Let us therefore add some observations to improve the situation. First: a botanical artist looks at plants with a different eye from the taxonomist – that’s why he is an artist and not a scientist. Fortunately, some overlap exists, where the two can meet.

The histogenesis of Bulb and trama tissue of the higher Basidiomycetes and its phylogenetic implications
Provedor de dados: 16
Autores: Reijnders, A.F.M.
At the base of the stipe in Agaricales basal plectenchyma is found which may enlarge to form a bulb. This tissue is not homogeneous. It is characterized by peculiar configurations: free tips of branches, sinuous hyphae, loops, spirals and rings (sometimes enclosing another hypha) and hyphal knots. The hyphal knots present themselves as bundles of hyphae, which may or may not be the centre of cell division, or as agglomerations of cells surrounded by coiled hyphae. The latter structure, present in many species of Agaricales, is found in its perfect form in the trama of the Amanitaceae, which recalls the trama of the Russulaceae. The young pileus trama of many species shows the same characteristics; these also occur in the trunk of Ramaria, in young bulbs of...

Leaf sheaths and obturators in Rutaceae – Pilocarpinae
Provedor de dados: 16
Autores: Kaastra, Roel C.
From morphological and anatomical study it is clear that the dilated leaf bases of Metrodorea can be regarded as sheaths. They are not homologous with the spines of Raulinoa, as suggested by Cowan. The outgrowths on the ovules and immature seeds of Pilocarpinae have to be regarded as obturators.

Systematic reviews on the Mesodesmatidae (Mollusca, Bivalvia) I. The Genus Monterosatus Beu, 1971
Provedor de dados: 16
Autores: Rooij-Schuiling, L.A. de.
In trying to identify a small Mesodesma from West Irian, New Guinea, much material in the collections of several museums was studied. As a guide for the identification I at first used the revision of the Mesodesmatidae by Lamy (1914), which is based exclusively on the collections of the Parisian museums. This publication, however, soon proved to be inadequate in view of the vast amounts of material in other collections. New ideas about the classification of the Mesodesmatidae prompted me to revise the systematics of this family, and preliminary publications (De Rooij-Schuiling, 1972, 1973) have already dealt with some aspects of this revision. The present paper is the first of a series of revisions in which all species of Mesodesmatidae will be described...

A monograph of the fern genus Bolbitis (Lomariopsidaceae)
Provedor de dados: 16
Autores: Hennipman, E.
The present study deals with systematic and taxonomic problems in the acrostichoid fern genus Bolbitis (Lomariopsidaceae). The idea came from Prof. Holttum, Kew, in view of his intended revision of the lomariopsidoid ferns for Flora Malesiana. Originally the study was confined to the Asian representatives. However, various problems remained unsolved after the study of these taxa alone, and it was decided to monograph the genus. The taxonomy of the genus Bolbitis was seriously misunderstood in the past—parallel evolution obscuring true relationships—and a rather intricate synonymy has resulted. A brief historical sketch of its taxonomic adventures is worked out. The gross-morphological criteria used for the discrimination of the species by Copeland (who...

On 27 May 1976 Peter Arnold Florschütz, bryologist, died at the age of only 53 at De Bilt, Netherlands. Only six weeks prior he had been hospitalized as a result of kidney cancer. His untimely death came as totally unexpected and shocking news to his friends and colleagues all over the world, many of whom had seen him in excellent health the year before at the Botanical Congress in Leningrad. He was a lector of botany and curator of the cryptogamic herbarium at the Institute for Systematic Botany and acting director of the Botanical Gardens of the University of Utrecht, the same institution where he had studied biology from 1941 to 1949.

A new subspecies of Ceroplophana modiglianii Gestro (Coleoptera: Scarabaeidae, Rutelinae) from Malaysia
Provedor de dados: 16
Autores: Kuijten, P.J.
In 1893, Gestro founded the genus Ceroplophana, only including the simultaneously described species C. modiglianii Gestro. He considered the genus — based on the only known specimen — closely related to Peperonota Westwood, Didrepanephorus Wood-Mason, and Dicaulocephalus Gestro. For rutelines, the males in these genera have strikingly developed secondary sexual characters. Gestro's species was the first representative from an insular locality of this South-East Asian group (Si Rambé, Batakland, North Sumatra; this locality is mentioned on the map in the report of the explorer who collected the material, Modigliani, 1891). Recently I could study seven ♂ of modiglianii from West Malaysia. They show striking differences from Gestro's description. Gestro's...

On the morphology of the ovules in Salacca (Palmae)
Provedor de dados: 16
Autores: Heel, W.A. van.
Female inflorescences in several stages of development of Salacca edulis Reinw. were collected from stands in the Kebun Raya at Bogor and near the village Depok, West Java. In addition to this, material of S. wallichiana Mart. collected in the Kebun Raya, Bogor, was used in this morphological study*). Salacca belongs to the subfamily Lepidocaryoideae of Palmae, which is distinguished by its large fruit scales. As one of the results of the present study I could observe that the early development of these scales takes place in the epidermal cells of the young ovaries. The Lepidocaryoideae are furthermore distinguished by the position of their ovules. In Palms there is one axillary basal ovule in each locule. Usually the ovules are ascendent and anatropous,...

The Pretoria method for localizing localities
Provedor de dados: 16
Autores: Steenis, C.G.G.J. van.
Localizing specimens and mapping localities has always been a tedious and time-consuming task for which much depends on the data mentioned on the labels. It has been found a blessing if collectors mention on labels the latitude and longitude. If this is given in an exact way it comprises degrees and minutes, e.g. 6° 45’ S, 141° 30’ E. If no dot-map is provided this appears to be a slightly clumsy formula in print and the question arises whether such exact figures are really needed. In scanning a geographical map the minutes will hardly mean something unless one uses local small-scale maps, as one minute is only a little more than 2 km in the terrain. In Pretoria only the degrees are given, joined into one figure, preceding the collector / after the...

Systematische Holzanatomie einiger Rubiaceen
Provedor de dados: 16
Autores: Koek-Noorman, Jifke.
The anatomy of the secondary xylem of the Rubiaceae confirms the relationship between genera and tribes as delimited and arranged by recent authors (Bremekamp, Verdcourt). Two character complexes can be distinguished, the distribution of which is in accordance with the classification of the genera and tribes and to a certain degree of subfamilies as well. Exceptions to this rule occur, but mostly in genera of an uncertain taxonomic position. Henriquezia is an example. Cinchona, by some taxonomists considered to be congeneric with Ladenbergia, differs in its wood anatomy from that genus and from the other Cinchoneae. Rubia fruticosa and other woody members of the chiefly herbaceous tribe Rubieae deviate so strongly in their xylem structure from the other...

Comparative lung-morphology in the genus Chamaeleo Laurenti, 1768 (Sauria: Chamaeleonidae) with a discussion of taxonomic and zoogeographic implications
Provedor de dados: 16
Autores: Klaver, Ch.J.J.
In this paper the lung-morphology of a large number of chameleons is described. Various characters can be distinguished, e.g. the septa-arrangement and the caecal outgrowths or “diverticula” on the ventral and caudal margin of the lungs. These characters are variable, but their shape often is characteristic of the species or the group of species. Next to C. pumilus (Gmelin, 1789), the only species known to lack diverticula so far, various other species without diverticula were found. Various lung-types, i.e. lungs with a similar combination of characters can be distinguished. Similarities in lung-structure tend to coincide with established affinities between species, but may also affirm assumed ones or even indicate new affinities. The geographical...

Further studies on Caribbean tenebrionid beetles

Autores: Marcuzzi, G.
The study of some newly collected material from the West Indies may justify a fourth paper on Caribbean Tenebrionidae in these “Studies”. Thanks to dr. P. WAGENAAR HUMMELINCK’S collecting work, the Tenebrionid fauna of the Antilles and the adjacent South American mainland shores may be considered to be pretty well known — at least as far as the Melasomes are concerned. Thus zoogeographical conclusions — though not differing essentially from those published in 1962 — appear to have a rather solid basis. Unfortunately much less is known about planticolous Tenebrionids, which anyhow are relatively less interesting for zoogeographical purposes, than the geophilous ones.

Some twenty-five years have passed since short descriptions were published of marine and saltpond habitats sampled in the Caribbean during three zoological collecting trips made by the author in 1930, 1936/37 and 1948/49 (these Studies, vol. 4, no. 17, 1953). Sampling of the shallow coastal waters of the Caribbean was continued in 1955, 1963/64, 1967, 1968, 1970 and 1973, during six visits the main purpose of which was not always the study of the marine fauna. Although collecting was done single-handed and rather incidentally, with no other equipment than a knife, fine-meshed nets, formaldehyde and alcohol, the material collected proved to be sufficiently valuable for scientific purposes to justify the publication of a list of the new marine localities.

Over het voorkomen van de Alpenrus
Provedor de dados: 16
Autores: Weeda, E.J.
This paper deals with the occurrence of Juncus alpino-articulatus subsp. arthrophyllus (syn. J. fuscoater) in the Netherlands, especially in Twente, the eastern part of the province of Overijssel. This Juncus is very rare in the Netherlands. Formerly, it had been recorded from some localities in the so-called Fluviatile district, chiefly along the river Waal; in this region it is restricted nowadays to one locality in the Ooijpolder near Nijmegen. In recent years it has been discovered in three localities in Twente, and also in the southern part of the province of Limburg. A description is given of two localities in Twente. They represent two different types of habitat of this rush: in one, it occurs in the transition zone between Molinia caerulea...

Gastroptychus Cavimurus sp. nov., a new Chirostylid (Crustacea, Decapoda, Anomura) from off the western coast of South America
Provedor de dados: 16
Autores: Baba, K.
During the second cruise of the Japanese Research Vessel "Kaiyo Maru" to the western coast of South America in 1968-69, Dr. Osame Tabeta of the Shimonoseki University of Fisheries, then on the staff of the Kyushu University, collected a number of galatheids off the northern Peruvian coast. All of those specimens have been placed at my disposal. Among them were a pair of chirostylids, careful examination of which showed that they belonged to an undescribed species of the genus Gastroptychus. In the meantime I also had a chance to examine unidentified galatheids in the collection of the Rijksmuseum van Natuurlijke Historie, Leiden, and found two chirostylids taken from off Ecuador, which proved to be identical with the Peruvian species.

Autores: Schuckard, Rob.
1. 2400 specimens were collected on Engelsmanplaat during 24 days in the period from the middle of May until the beginning of August 1975. This small, sandy, island is situated between Ameland and Schiermonnikoog. It is inundated several times a year. The 2400 specimens belong to more than 83 species. More than 1700 specimens attributed to 46 species were identified with certainty. 2. Judging from the literature 93% of the 1700 specimens seem to be able to develop in biotopes as present on the Engelsmanplaat. Three species, Fucellia maritima Hal., Rhicnoessa grisea Fall., and Helcomyza ustulata Curt. were present in such a high number, that it is quite reasonable to suppose they can survive on Engelsmanplaat during the whole summer.

Hydroids from French Polynesia with notes on distribution and ecology
Provedor de dados: 16
Autores: Vervoort, W.; Vasseur, P.
INTRODUCTION  Distribution and ecology of hydroids from coral reefs of high islands and atolls of French Polynesia so far have received little attention. Redier (1967, 1971) published a preliminary list of 14 species from Salvat's collections, sampled during several trips to Tahiti, Tuamoto (Mururoa, Reao and Maturei Vavao Atolls), to the Australes Islands (Rapa) and to Gambier.   The present paper results from researches carried out by one of us (P.V.)  concerning the benthic bionomy of reef sciophilous communities of hard bottoms. They have been carried out at Tiahura, Moorea, Society Islands (fig. IA) and on Takapoto Atoll, Tuamoto Archipelago (fig. 2A) in 1973 and 1974. They gave us occasion to compile a revised list of about 22 species of hydroids...

Developmental stages of thoracic chaetotaxy of Protaphorura armata (Tullberg, 1869) sensu Gisin, 1952, 1960, and of P. furcifera (Börner, 1901) are analysed. The chaetotaxy of the first juvenile stage is identical in both species and oligochaetose, it closely resembles the chaetotaxy found in most Hypogastruridae. The plurichaetose condition, typical of the genus Protaphorura, is developed by a gradual orderly appearance of supplementary setae, among which the primary setae still can be recognized.

From 1933 to 1962 he was director of the Rijksherbarium and although the day of his retirement lies some 15 years behind us now, he is still remembered in our institute for his pleasant personal qualities. The Rijksherbarium as it is today we owe for a large part to his vision and work during the 29 years of his directorate. He broadened the basis of the institute’s research but kept intact its specialization; he succeeded in obtaining valuable collections; he started a programme of botanical expeditions; he provided a home for the Flora Malesiana, to mention some of his accomplishments.

In 1828 (p. 1-2), John Edward Gray described the spinner dolphin as follows: Delphinus longirostris, n. - Osse palatino carinato, postice convexo; rostro longissimo attenuata, supra depresso, lineâ mediâ elevatâ; dentibus parvis utrique 48/è48 50/50 ." To this Latin diagnosis he added: "Inhab....... Cranium in Mus. D. Brookes. The beak is more slender and depressed than that of D. delphis; the palate bone more strongly keeled; and the elevated central process of the upper surface of the beak broad and convex. Length of the head 6 inches; beak 11 1/2. Breadth of the latter at its base 3 inches." From the description it is evident that the skull on which the diagnosis was based formed part of the private museum of D. Brookes in London. In the same year in...

Systematics and evolution in the West Indian iguanid genus Cyclura
Provedor de dados: 16
Autores: Schwartz, Albert; Carey, Michael.
Throughout the Greater Antilles, the Virgin Islands, the Cayman Islands, the Bahama Islands, and the Turks and Caicos islands occurs a group of moderate to very large lizards of the iguanid genus Cyclura. These ground iguanas form a conspicuous element of the herpetofaunas of their respective islands. In some areas, the ground iguanas are still very abundant, in others somewhat less so, and in still others they have either become recently extinct or are known only from fossils. Fourteen species are currently recognized, with the largest percentage occurring in the Bahamas Islands. There has been no recent taxonomic treatment of the genus. That of BARBOUR &amp; NOBLE (1916) was the only systematic study, and these authors were very greatly hampered by far...

Mycena galericulata—usually 2-spored?
Provedor de dados: 16
Autores: Maas Geesteranus, R.A.
Mycena galericulata (Scop. ex Fr.) S. F. Gray is a common agaric, widely distributed in Europe and readily recognized. Whether this also applies to extra-European areas is here left out of consideration, while the actual investigation is concerned only with the situation in the Netherlands. As far as I have been able to check, the general opinion in Europe has been and still is that M. galericulata occurs predominantly with 2-spored basidia. A few references may be cited to substantiate this statement; some care had to be taken in consulting those authors who regarded M. galericulata and M. rugosa Fr. (now considered to represent one and the same species) as distinct.

Since our knowledge of the greater part of the Tipulidae of the Canary Islands, Madeira and the Azores is poor, the types of most species described from these islands have been studied, and critical species are redescribed. One new species, Limonia (Dicranomyia) michaeli n.sp. is described, and a list of all known species is provided. The taxonomic and distributional data suggest that Tipulidae arrived on these islands in three invasion waves, viz. a first in early Tertiary, a second in late Tertiary and a third in more recent times. Species that came in the first wave either colonized Madeira and the Azores or the Canary Islands, the second wave only, colonized Madeira and the Canary Islands, and the third invasion finally reached the Canary Islands only.

The pattern of vascular bundles in the stamens of Nymphaea lotus L. and its bearing on stamen morphology
Provedor de dados: 16
Autores: Heel, W.A. van.
In 1969 I published, together with P. G. Heinsbroek, a paper on the anatomy of the stamens of Victoria amazonica. The flowers used in that study came from plants which were cultivated in the green-house of the Leiden Botanic Garden. Because the possibility could not be excluded that the structures then observed were partly the effect of greenhouse conditions, I subsequently took the opportunity to study flowers of well developed plants, which were cultivated in the open air under the tropical conditions of the Botanic Garden at Bogor*). The results were exactly the same. Apart from the set of central vascular bundles, normal in laminar structures, there proved to be a peripheral sheath of bundles consisting of abaxial bundles, terminating half way up the...

On the relation between movements and the shape of somites in early embryos of the teleost Brachydanio rerio
Provedor de dados: 16
Autores: Raamsdonk, W. van; Pool, C.W.; Mijzen, P.; Mos, W.; Stelt, A. van der.
As a working hypothesis it is supposed that in the teleost Brachydanio rerio, the muscle contractions, the growth, and probably some other factors, cause the first changes in the shape of the somites. Furthermore, the movements of the embryo could yield the forces by which the somites are brought to their theoretically optimal shape. In order to test this hypothesis, we investigated the somite shape and structure of spontaneously immobile embryos. Although the results are difficult to interpret, they certainly do not contradict the hypothesis. For further analysis we applied two kinds of lesions in order to immobilize early embryos: removal of the brain, and damage to the midbody somites. The results of these experiments indicate that both the development...

Multivariate assessment of the phenetic affinities of Australasian oystercatchers (Aves: Charadriiformes)
Provedor de dados: 16
Autores: Baker, Allan J.
Phenetic affinities of Australasian oystercatchers were elucidated by multivariate statistical analysis of seven morphometric characters taken from museum skins. Nineteen operational taxonomie units (OTUs), representing all the currently recognized species and most of the subordinate taxa, were used to calibrate morphological variation in Australasian Haematopus against the range displayed by the Haematopodidae. The rather homogeneous nature of variation among OTUs was not well suited for analysis by hierarchical clustering methods, but a non-hierarchical ordination method utilizing both principal components and nonmetric scaling produced excellent summaries of the similarity matrices.

Autores: Stelt, A. van der.
Prof. Dr. Gerard Barendrecht was born on the 9th of October 1906 in Hilversum. After his final examinations in Kampen in 1923 there came a year of private studies of Greek and Latin. These formative years resulted in a continuing interest in the classical writers which he still reads as a relaxation from more strenuous tasks. On the other hand, the polders in the neighbourhood of Kampen gave the inspiration to the writing of the “Glorie van ons polderland” (“Glory of our polderland”). In 1924 he entered the University of Amsterdam as a student in biology where he took his “doctoraal examen” (master’s degree) in 1929. His doctor’s degree dates from the 20th of January 1932. His thesis “Die Corpora pedunculata bei den Gattungen Bombus und Psithyrus” is an...

Studies on Colombian cryptogams. IIA. Hepaticae – Oil body structure and ecological distribution of selected species of tropical Andean Jungermanniales
Provedor de dados: 16
Autores: Gradstein, S.R.; Cleef, A.M.; Fulford, M.H.
This paper is the second (Florschütz &amp; Florschütz-de Waard 1974) in the series of reports on cryptogams of Colombia, especially the high Andean bryophytes and lichens, in the framework of recent phytosociological and ecological studies in the area by A. M. Cleef and T. van der Hammen (Amsterdam) and his collaborators. The aim of these studies is to prepare comprehensive descriptions of the various Andean biota of Colombia as a basis for an evaluation of the biological diversity of the Andean environment of Colombia. This paper deals with the Hepaticae or liverworts and focuses on the structure of the oil bodies in the liverwort cell and the geographical and ecological distribution of the species. There are few papers on tropical Andean liverworts. The...

Notes on Southeast Asian Porcupines (Hystricidae, Rodentia) II. On the taxonomy of the genus Atherurus F. Cuvier, 1829
Provedor de dados: 16
Autores: Weers, D.J. van.
The individual and geographical variation of the Brush-tailed Porcupine, Atherurus F. Cuvier, 1829 from eastern India, Burma, Thailand, Laos, China, Hainan, Peninsular Malaysia and some adjacent islands has been studied from material in European and American museums. Information about this material is presented and the status of ten specific and subspecific names is discussed. Only one species, Atherurus macrourus (Linnaeus, 1758) is recognized and insufficient arguments were found for the distinction of subspecies on the basis of the small samples at present available. An error in Van Weers (1976: 19) concerning the name of the type species of Trichys Günther, 1877, is corrected in a foot note.

The author mentions the finding of a great number of seeds of the tropical Entada gigas (L.) Fawcett et Rendle in november 1976 along the beach of Walcheren (prov. of Zeeland) and supposes that the seeds are probably a part from a ship-load or transported on long distance by the sea. In a postscriptum Dr. Leenhouts is of the opinion that Gulfstream transport is highly improbable, the more so as the seeds of Entada gigas are apparently used pharmaceutically.

It is the genera of threatened plants that need attention
Provedor de dados: 16
Autores: Jacobs, M.
Plant species protection seems a popular concept nowadays, which leads to the preparation of Red Data Lists, and of sheets for recognition. Such an approach may be sensible in civilized temperate countries with a poor flora widely known; in the humid tropics it is out of the question. There are too many species, and neither books nor people are available to identify them, not to speak of implementation. Besides, dealing with species as isolated entities easily creates the impression that protecting such species would be of any help, to the neglect of the only effective way of conservation: wholesale protection of primary ecosystems. The latter concept, however, is difficult to convey to the public; it is too complex to create a lasting, vivid impression....

Aanwinsten voor de Nederlandse flora, hoofdzakelijk uit 1967-1974
Provedor de dados: 16
Autores: Ooststroom, S.J. van; Mennema, J.; Adema, F.
In 1966 the decease of Th. J. Reichgelt caused a stagnation in the regular publication of acquisitions to the adventitious flora of the Netherlands. Only VAN OOSTSTROOM (1970a and b), ADEMA (1974), and VAN DER MEIJDEN (1975) incidentally continued this series. From 1975 onward the acquisitions to the adventitious flora of the Netherlands — and the new escapes from cultivation — are published in the annual lists with records of rare species. The present publication has the purpose of filling up the gap between 1967 and 1974 and includes: A. Native taxa — a few infraspecific taxa new for the Netherlands; B. Adventitious species; C. Species escaped from cultivation. In the lists B and C the original area of the species has been added.

Senecio congestus (R. Br.) DC. in Zeeland.

The structure of the terminal filament, the ovariole sheath and the oviduct musculature of the Colorado Beetle (Leptinotarsa decemlineata Say, 1824)
Provedor de dados: 16
Autores: Akster, H.A.; Smit, W.A.
In the Colorado Beetle, the terminal filament cells resemble the epidermal cells which connect muscle cells with the cuticle, the so-called tendon cells. They contain many microtubules which have projections interconnecting them. The microtubules are also connected by these projections to desmosomes. The tunica propria is a basement membrane-like layer of low elasticity. It separates the terminal filament from the germarium. The outer ovariole sheath is a muscle sheath which is continuous with the muscle sheath around the oviducts. The whole muscle sheath consists of a monolayer network. Sarcolemmal invaginations at the I band and at the Z line probably form part of one T system. The cuticle of the common oviduct has scales with long caudally directed...

Oil bodies in leaves variable in number, (2-)3-8(-13) per cell; subglobose to, more rarely, ellipsoid, 4-8(-12)x4—6 μm; colourless, rather coarsely to finely granulosepapillose, becoming homogeneous upon degeneration (Colombia, Cundinamarca, Cleef 78b, 3410b, 397b; ibid., Cauca, Cleef 679). Variation in number and morphology of the oil bodies apparently is characteristic for Lophocoleaceae, since it has been found not only in this and the other species of Lophocolea reported here but also in European material of Lophocolea and Chiloscyphus (unpubl. obs.).

Autores: Dieleman, Jan; Pinkster, Sjouk.
In the autumn of 1975 and in the spring of a new survey of the range of Gammarus tigrinus Sexton, 1939, was carried out, especially at the borders of the 1973 range. Considerable range extensions were found in the north-eastern parts of the province of Groningen, the Kampereiland (province of Overijssel), in the Deltaic Region and in some more or less isolated areas in the province of Zuid-Holland. In most of the newly invaded areas G. tigrinus has replaced the indigenous Gammarus species. Sampling along the Dutch-German border revealed that no invasion has taken place from any of the German populations. A fungus was found which appeared to be pathogenic for G. tigrinus.

The Herbarium is arranged according to Christensen’s Index Filicum (1905). I examined all the Old World specimens in Dryopteris and Aspidium, both in the general herbarium and in the separate herbarium for China and Japan. It appears that the genera segregated by Christensen from Dryopteris (e.g. Pteridrys) in the Third Supplement to the Index (1954) have not been segregated in this herbarium. Type specimens have been removed by Dr. A. Bobrov and are in a separate series arranged alphabetically under basionyms. Selection of types was done rather hastily, and many of the specimens need critical study. For example, most Wallich specimens are filed as types of the names in Wallich’s catalogue, with no check as to whether the names have been subsequently...

Distribution and transport of Fennoscandinavian indicators : a synthesis of data from the literature leading to a reconstruction of a pattern of flowlines and ice margins of the Scandinavian ice sheets
Provedor de dados: 16
Autores: Overweel, C.J.
Detailed indicator counts in the literature on areas south and east of the Baltic were revaluated on the basis of the main ice movement directions of the last glacial in Fennoscandia. This revaluation resulted in a distribution pattern of indicators which partially coincides with the general trends of ice movement. This holds for both the Weichselian and the Saalian. The other part of the indicator distribution is of Baltic origin. The interrelationship found between flowline and distribution pattern was further analysed and elaborated, which led to a reconstruction of the directions of ice movement and outline forms of the Scandinavian ice sheets. The peripheral glacier-margin drainage was incorporated into the reconstruction, and the resulting...

Application of the priority rule of zoological nomenclature led to the renaming of one species, while in another case a different generic name is applied. A complete description of the five species is given including colony form, morphology of the living polyps, morphology and morphometry of the spicules. The latter were observed by means of light microscopy and scanning electron microscopy. The ecology of each species is briefly described.

The respiratory area of the gills of some teleost fishes in relation to their mode of life

Autores: Jager, S. de; Smit-Onel, M.E.; Videler, J.J.; Gils, B.J.M. van; Uffink, E.M.
From computations (by means of graphic interpolation and graphic integration) of the respiratory area, and transposition of these values to a respiratory area of a standard fish of 200 g (A200 value), it could be made plausible that the relation between respiratory area and mode of life of the fishes mentioned in this paper (Cod, Plaice, Conger, Flounder, Dab and Pike) fits in with the general pattern found in an earlier paper, although intraspecific differences were sometimes considerable. In comparison with A200 values of other species, the Cod has a respiratory area that fits in with his mode of life and that of other typical sprinters. The Flounder has a considerably larger respiratory area than Plaice and Dab. Flounder feeds mainly on small fishes,...

In recent years the wood collection at the Rijksherbarium was greatly expanded following a renewed interest in wood anatomy as an aid for solving classification problems. Staff members of the Rijksherbarium added to the collection by taking interesting wood samples with them from their expeditions (e.g. from Sumatra by De Wilde &amp; De Wilde-Duyfjes, from Borneo, the Philippines and New Guinea (climbers!) by Jacobs, from Thailand by Van Beusekom and Geesink, and from various localities in Indonesia by De Vogel). The nucleus of the Leiden wood collection remains the BW series from New Guinea expanded by collections by Kalkman, Vink and Van Royen. In spite of these valuable resources to draw upon for comparative wood anatomical work the Leiden wood...

Provedor de dados: 16
Autores: Kramers, P.; Moen, J.E.T.; Roos, P.J.
In the Abcoudermeer, a small lake S.E. of Amsterdam, the rubble banks were investigated on macro-invertebrates. At least 46 species were encountered, insects and their larvae not included: 1 species of sponge, 1 species of hydrozoan, 6 species of free-living flatworms, 17 species of snails, at least 3 species of mussels, 8 species of leeches, 3 species of crustaceans and 7 species of bryozoans. Differences between two banks are discussed.

Conservation of nature in the marine environment
Provedor de dados: 16
Autores: Korringa, P.
It was on land that the need for conservation of nature was first felt. Setting aside of noteworthy areas for that purpose often led to a serious clash with other interests. Therefore the need was felt to formulate on a scientific basis which factors should be carefully considered in deciding which sections of the continents should be destined for nature conservation. It turned out that all these factors operate directly or indirectly in the interest of man himself, not for nature as such. An effort is made to study the applicability of all these factors in the marine environment. Comparison with the situation on land leads to the conclusion that the recreational value of the coral reefs in tropical areas requires above all measures for their protection,...

Microparasellidae (Isopoda, Asellota) from Bonaire
Provedor de dados: 16
Autores: Stock, Jan H.
During a study still in progress on the fauna of phreatic waters of various West Indian islands, a number of isopods of the family Microparasellidae were obtained. Although material from some 20 Caribbean islands was examined, only the island of Bonaire yielded microparasellid isopods so far. These animals are described in the present paper. Up to now, the only other West Indian records for the family are those of COINEAU &amp; BOTOSANEANU, 1973, from Cuba. The methods employed are the same as in my previous study (STOCK, 1976a) on the Antillean Thermosbaenacea. All chlorinities have been determined with the aid of an E.E.L. electric chlorinimeter.

Autores: Rähle, W.
Durch das Entgegenkommen von Herrn Dr. C.

J. P. M. Clerx gesammelt worden waren. Anatomisch zeigten die Tiere nach einer ersten, oberflächlichen Betrachtung eine gewisse Ähnlichkeit mit dem erst kürzlich aus der selben Gegend (allerdings aus größerer Höhenlage) beschriebenen Milax macedonicus Rähle, 1974. Was Körperform und Färbung betrifft, so weisen die aus Ohrid stammenden Tiere jedoch erhebliche Unterschiede auf. Eine eingehendere Untersuchung ergab schließlich, daß die vorliegenden Exemplare zu...

Site selection and growth of the larvae of Eylais discreta Koenike, 1897 (Acari, Hydrachnellae)
Provedor de dados: 16
Autores: Davids, C.; Nielsen, G.J.; Gehring, P.
The distribution of the larvae of Eylais discreta on the abdominal tergites of the host species Sigara striata, S. falleni and Cymatia coleoptrata is examined. On S. striata and S. falleni the segments 3 and 4, on C. coleoptrata the segments 2 and 3 are successively preferred. There is but little influence of multiple infestations on this distribution. The growth rate on the various tergites of S. striata is similar, while on C. coleoptrata a possible difference could not be proved statistically. The larvae of E. discreta generally hibernate on the host; during this phase there is little growth; not until March-April they start growing faster. The larvae on C. coleoptrata are retarded in growth compared to those on S. striata. The larvae on S. falleni do...

Provedor de dados: 16
Autores: Wear, R.G.; Holthuis, L.B.
INTRODUCTION Ligur uveae is generally considered an anchialine species (found in land-locked, generally supralittoral saltwater pools) with the type locality given simply as "Uvea, Loyalty Islands" by Borradaile (1899). The species is widely distributed geographically, although locally evidently confined to a very restricted habitat. Its known range extends from the western Indian Ocean to Polynesia: Aldabra, western Indian Ocean (Borradaile, 1917; Gordon, 1936); Halmahera, northern Moluccas, Indonesia (Holthuis, 1947; 1963); Uvea, Loyalty Islands (Borradaile, 1899; Gordon, 1936); Sayawa Islet near Uvea (Monod, 1968); Vatulele Island, Fiji Archipelago (Gordon, 1936; Derrick, 1957; Marden, 1958; Reed &amp; Hames, 1967); Vanua Vatu and Vanua Levu Islands,...

Based on type studies, the following genera are reclassified: Petalosporus, Disarticulatus, and Plunkettomyces as synonyms of Arachniotus; Gymnascella, Gymnoascoides, Macronodus, Tripedotrichum, and Uncinocarpus as synonyms of Gymnoascus, and Kuehniella as a synonym of Arachnotheca. The question of the type species of Arachniotus is discussed. Rollandina is considered to be a nomen confusum; sensu Apinis (1970) it belongs to Nannizzia. The accepted genera of the Gymnoascaceae are briefly reviewed.

Descriptions of two new Ceriantharia from the Caribbean region, Pachycerianthus curacaoensis n. sp. and Arachnanthus nocturnus n. sp., with a discussion of the cnidom and of the classification of the Ceriantharia
Provedor de dados: 16
Autores: Hartog, J.C. den.
Two new Ceriantharia, Pachycerianthus curacaoensis and Arachnanthus nocturnus, both from the Caribbean region, are described. It is recommended to avoid the terms proto- and metamesenteries in taxonomie descriptions. The cnidom of the Ceriantharia is discussed; a subdivision of the spirulae (=b-rhabdoids) and penicilli ( = p-rhabdoids) differing from that of Schmidt (1972) is given. The anoplotelic character of the terminal tube of the penicilli (Schmidt, 1972) is doubted on the basis of light microscopical investigations. Mainly on the basis of the study of Botruanthus benedeni (Torrey &amp; Kleeberger, 1909) (Botrucnidiferidae), the 2 newly described species (respectively belonging to the Cerianthidae and the Arachnactidae), and of the data available in...

Austrobaileya replaces the Contributions from the Queensland Herbarium, and was devised to accommodate also shorter taxonomic notes. The Contributions amount to 20 numbers, with one article each; a cumulative index of names is in no 20, p. 73-88. In format and execution Austrobaileya resembles its predecessor but the useful page heads should be retained. Volume 1 number 1 (1977) was received in March 1978. It carries 9 papers on 74 pages, and a map with subdivisions of Queensland on the back flap. Frequency and price are unknown. Editor: L.

Notes on the nasal tract complex of the Boutu, Inia geoffrensis (De Blainville, 1817) (Cetacea, Platanistidae)
Provedor de dados: 16
Autores: Schenkkan, E.J.
The anatomy of the nasal passage of three specimens of the Boutu has been studied. The various diverticula appear to be aberrant from those described for other Platanistidae. The vestibular airsac system has developed into one enormous diverticulum. Except for a narrow region caudal to the blowhole, the total maxillary area caudal to the orbits is covered by this somewhat dome-shaped airsac system. The dorsal and rostral aspects of the vestibular system are strikingly symmetrical as are also the deeper parts of the nasal passage. The caudal parts of the nasofrontal diverticula are well developed, rostral parts are tubular and relatively small. Accessory air sacs are lacking and the premaxillary diverticula are broad, but their lumina rostral to the bony...

Confusions arising on the taxonorny of Sagitta pacifica. S. bedoti and S. pulchra are mainly the result of imprecise and subjective descriptions. A new modern account on two of the three species as they appeared in plankton samples collected off the colombian Pacific and the Bight of Panama is provided, Including meristic and morphological information. For the third species S. bedoti, only the relevant meristic and morphometric information gathered is included since publislicd accounts are adequate. It is hoped that this work will represent a contribution in future taxonomic and ecological studies on these species.

Durante el año de 1974-1975 se realizó un estudio preliminar sistemático y ecológico del fitoplancton en la Bahía de Nenguange, siendo identificadas setenta y cuatro especies. Las variaciones de temperatura y salinidad como la diversidad de las especies (número de especies más una medida relativa de abundancia), merecieron especial atención durante las épocas de mayor y menor precipitación. El mayor florecimiento que se pudo detectar, está integrado por diatomeas en su mayoría y comienza con la aparición de la estación lluviosa. Durante este periodo, la salinidad fue mínima y la temperatura máxima.

Composition, transport and origin of sediments in the Schelde estuary
Provedor de dados: 27
Autores: Wartel, S.
The grain-size characteristics (grain-size distribution, comparison of one percent value (C) of a given grain-size distribution with the median value (M) in so-called CM-patterns, silt/clay ratio's) of the Schelde estuary are distributed in relation to the existence of a turbidity maximum. Fine sand, silt and clay are deposited, while fluid mud occurs. Towards the North Sea, as well as in an upstream direction, the sediments become much coarser. Silt, clay and part of the sand are derived from the river drainage basin. Sands are also brought into the estuary from the North Sea. Flocculation is important as a depositional agent. However, deflocculation in a seawards direction, favouring seawards transport of silt and clay particles, is assumed. Movement of...

Occurrence of &lt;i&gt;Artemia&lt;/i&gt; in nature and its morphological development from nauplius to adult
Provedor de dados: 27
Autores: Sorgeloos, P.
The first written record of the existence of the brine shrimp only dates back to 1755 (Schlosser in Kuenen and Baas-Becking, 1938). Nonetheless this "filtering animal" was already known since much longer times by different ethnic groups who attributed a better salt production in the brine pools to the presence of &lt;i&gt;Artemia&lt;/i&gt; ; hence its popular names such as brineworm, Salztierchen, verme de sale, sóféreg, Bahar el dud, Fezzanwurm, etc. Despite the primitive optical equipment available at that time Schlosser's drawings were very detailed and rightly give the adult animal 11 pairs of thoracopods. Several other scientists, including Linnaeus (1758), later described adult &lt;i&gt;Artemia&lt;/i&gt; with only 10 thoracopods. This controversy...

Some aspects of respiration in &lt;i&gt;Artemia salina&lt;/i&gt; L.
Provedor de dados: 27
Autores: Decleir, W.; Vos, J.
The most striking phenomenon in the physiology of &lt;i&gt;&lt;i&gt;Artemia&lt;/i&gt; salina&lt;/i&gt; L. is the diapause phase under the form of a cyst in the gastrula stage. Thus for example, can dried cysts resist to extreme stress conditions, without affection of their hatchability after hydration. They withstand complete dehydration exception made for some traces of residual water (Whitaker, 1940); they resist to a temperature of 100°C for more than an hour (Hinton, 1954) , and can be kept at the absolute zero temperature for an indefinite period (Skoultchi and Morowitz 1964). Eventhough hydrated cysts are less tolerant of these "extravagant" conditions, they nevertheless are only slightly sensitive to anoxia for periods up to 5 months (Dutrieu,...

Decapsulation of &lt;i&gt;Artemia&lt;/i&gt; cysts: a simple technique for the improvement of the use of brine shrimp in aquaculture
Provedor de dados: 27
Autores: Sorgeloos, P.; Bossuyt, E.; Laviña, E.; Baeza-Mesa, M.; Persoone, G.
Although it is a common practice in different disciplines of fundamental research on the brine shrimp, and despite the very interesting applications that it offers for the use of &lt;i&gt;Artemia&lt;/i&gt; in aquaculture, the "decapsulation" technique, which removes the outer layer of the cyst shell of &lt;i&gt;Artemia&lt;/i&gt; , is not known to shrimp and fish aquaculturists. The present paper describes the technology developed by the authors for the routine decapsulation of &lt;i&gt;Artemia&lt;/i&gt; cysts. The advantage which result from the use of decapsulated cysts in aquacultural hatcheries are discussed.

The fate of old bottle-nosed dolphins, &lt;i&gt;Tursiops truncatus&lt;/i&gt;, in nature as revealed by the condition of their skeletons
Provedor de dados: 27
Autores: De Smet, W.M.A.
Comparison of the skeletons of stranded or river-dwelling bottle-nosed dolphins with those of delphinarium specimens revealed that many of the former animals had suffered from various diseases. Most wild specimens have broken or lost a part of their teeth or even all of them. In a few cases they show signs of bone erosion (probably by abscesses), bone neoformation, and in a single case a broken mandible. Teeth abrasion may start early in life. Also delphinarium specimens may have broken teeth. Broken ribs can be found in half of the number of specimens. In the wild the ribs healed nicely, but in the delphinarium they hardly did. All the wild specimens show periosteitic phenomena to some degree. Delphinarium specimens are not excepted from them. In one of...

The realized and intrinsic rates of increase of several meiobenthic populations are compared. The realized rate of increase is remarkably similar among four species of copepods, which leads to the conclusion that dominance is not a function of rate of increase or parameters influencing this rate. The result is investigated in the light of Vandermeer's (1975) Beta-competition. There is also a remarkable agreement between the values of the predator &lt;i&gt;Protohydra leuckarti&lt;/i&gt; and its principal prey &lt;i&gt;Tachidius discipes&lt;/i&gt;. The intrinsic rates of natural increase vary more, but are a linear function of temperature in all species investigated. This is in agreement with the theory that natural selection acts against nonlinear dynamic...

On the role of heterotrophic bacteria in marine ecosystems: some problems
Provedor de dados: 27
Autores: Joiris, C.
Resulting from synecological studies in some areas of the southern North Sea, a contradiction becomes evident between measurements of primary production and determinations of the activities consuming organic matter. In the Southern Bight, the consumption is 10 times higher than the production. This means that the primary production has been underestimated, and/or the consumption over-estimated. In order to discuss the validity of the methods used for determining the respiration activities, some results are presented: (a) during a 24-h cycle at the Sluice-Dock of Ostend, the variations of the oxygen concentration in the water are explained by the measured activities and diffusion fluxes; (b) two different methods are shown to give comparable results: the...

Systematics and evolution in Polycystididae (Turbellaria, Kalyptorhyncia)
Provedor de dados: 27
Autores: Schockaert, E.R.
Possible evolutionary trends within Polycystididae have been indicated by Karling (1956) while studying the male genital organs of seyeral turbellarian groups. For the moment his ideas seem the most valuable basis for establishing an intrafamiliar system of Polycystididae, and have hence been applied formally (Schockaert, 1974). However, it can be demonstrated with several examples that the underlying principles prove to be unsatisfactory when one tries to apply Hennig's methodology:-the subfamily Duplacrorhynchinae Schockaert &amp; Karling, 1970, can be recognized as containing the most plesimorph polycystidids; a synapomorph character that would give us an indication of the monophyly of this taxon is lacking;-the homology of some glandular elements (al!...

The branchial gland from the cuttlefish (cephalopod mollusc) consists of extensively irrigated tissue, which shows a typical ultrastructure of protein-secreting cells: prominent nucleolus, elaborate system of granular endoplasmic reticulum and active Golgi apparatus. The possible hemopoietic role of the gland is sustained by our biochemical results.

Copepod biomass in an estuarine and a stagnant brackish environment of the S.W. Netherlands
Provedor de dados: 27
Autores: Bakker, C.; Phaff, W.J.; van Ewijk-Rosier, M.; De Pauw, N.
In the mesohaline zone of the Westerschelde estuary &lt;i&gt;Eurytemora affinis&lt;/i&gt; is the dominant copepod, demonstrating large biomass values nearly throughout the year. In the meso-polyhaline Lake Veere &lt;i&gt;Acartia tonsa&lt;/i&gt; is abundant, mainly during summer. In spring a small population of &lt;i&gt;Eurytemora americana&lt;/i&gt; is found. The tidal estuary harboured far denser copepod populations throughout the year than the stagnant brackish lake water. The average yearly copepodid + adult biomass in the Westerschelde estuary was approx. 850 mg/m³ (wet weight), in Lake Veere approx. 130 mg/m³. Temporarily low oxygen values did not influence negatively the copepod populations in the Westerschelde estuary. The seasonal distribution of...

Vertical distribution of meiofauna and the efficiency of the Van Veen grab on sandy bottoms in lake Grevelingen (the Netherlands)
Provedor de dados: 27
Autores: Heip, C.H.R.; Willems, K.A.; Goossens, A.
Comparison of density estimates of Nematoda and Harpacticoida obtained by a Van Veen grab and SCUBA diving from a sandy sediment in shallow water shows that Harpacticoida are sampled efficiently with the grab but Nematoda are not. For the Nematoda, total density is underestimated and the relative abundance of surface-dwellers is overestimated. Samples obtained with a Van Veen grab from which the material is collected in a bucket and subsampled afterwards have a much smaller statistical variability than samples obtained with other methods.

The rudiments of the "hepatopancreas" appear early, in stage 20, as a pair of diverticula, given off from the midgut. The anterior part which lies against the yolk-sac will become the "liver". The growth of the liver exhibits a close relationship to the development of the inner yolk-sac. An electron microscopic study has been made of the hepatic epithelium at different embryonic stages. From stage 27, the cytologic aspects of the hepatic cell (presence of "balls", cytoplasm with well developed granular endoplasmic reticulum and free ribosoms...) give evidence of secretory activity. These ultrastructural features show that the liver becomes functional and allow us to think that it plays a part in the embryonic metabolism during the last stages of...

Spatial segregation in copepod species from a brackish water habitat
Provedor de dados: 27
Autores: Heip, C.H.R.; Engels, P.
The segregation along the horizontal space dimension of the niche has been investigated in six copepod species occurring together in a brackish water habitat.All but one species show an aggregated pattern which may be described by a negative binomial distribution. The aggregations are small with a radius of 5-15 cm and are distributed randomly in the habitat. Aggregation of different species do not overlap; niche-overlap in this dimension show a somewhat wider utilization of space by the dominant species and insignificant overlap between species; there was no competition for space at the time of the investigation.

DEMAND, SUPPLY AND PRICE PREDICTION OF RICE IN TAIWAN FROM 1976 TO 1985
Provedor de dados: 31
Autores: Lee,   Wun-Chi.
Taiwan is located in the subtropical area of the Far East.  With the benefit of suitable weather, average temperature just under 71 F in the north and nearly 76 F in the south, and with the yearly precipitation around 75 inches, rice has been the self sufficient staff crop in Taiwan.  Even in the early eighteenth century, Taiwan exported rice to support the supply in Mainland China.  Rice is a necessity for Taiwanese.  A sufficient supply and stabilization of its price are relevant to the whole economy and society.  Because of the development of industry and economic growth, a lot of cultivated land has been transferred from rice production to industrial or architectural utilization under the principle of comparative advantage since 1958.  The benefit per...

EFFECTS OF MINERAL DEVELOPMENT ON THE ECONOMY
Provedor de dados: 31
Autores: Snape,   Richard H.
R. G. Gregory's article on the effects of mineral discoveries on the Australian economy (Australian Journal of Agricultural Economics, August 1976) has attracted much attention. While the partial-equilibrium nature of his model has enabled it to be absorbed readily, it has the usual theoretical limitations of such analyses.  Allowing for general equilibrium repercussions, but still accepting his general assumptions, some of Gregory's conclusions regarding the impact of new mineral discoveries require modification or extension:  (a) Although production of goods other than minerals can be expected to decline, the production of some goods in this category may rise;  (b) A social gain is still possible even if outputs of other goods do not change;  (c) While...

Increasing interest in the federally owned lands by individuals and groups representing a broad cross section of society has intensified public land management problems. Pressures for preservation, conservation, and additional non-market uses have resulted in management conflicts. Economic intelligence could contribute to improved decision making by federal agencies charged with public land management. However, inadequate past research  attention related to economic problems of public lands presently precludes an optimum input from economists. Articulation of problem areas and economic issues is necessary for developing meaningful research priorities. This article identifies some elements of  the problem and suggests some potentially rewarding areas for...

A widening range of rural adjustment assistance measures is being utilised, thereby increasing the range of government organisations involved. In choosing between these measures additional government and non-government research is required, with proposed policies accounting for the division of responsibility for assistance that exists between government organisations. There is also a need for greater policy co-ordination between these organisations, and a proposal for the establishment of a N.S.W. Rural Adjustment Advisory Council is outlined.

FACTOR SUBSTITUTION IN AUSTRALIAN AGRICULTURE
Provedor de dados: 31
Autores: Vincent,   David P.
Studies of the ease of substitution between inputs in production have generally been carried out within a production framework of an explicit functional form. In this study, a somewhat different approach is followed. A model of derived demand for primary factors of production, land, labour and capital is formulated to enable inferences to be made about the characteristics of the unspecified production function. The model is used to obtain estimates of the pairwise Allen-Uzawa substitution elasticities which are secondary parameters of the underlying production function. The reported FIML estimates from aggregate time series data for the period 1920/21 to 1969/70 indicate very low and marginally different substitution elasticities between different pairs of...

RURAL PRODUCT PROMOTION: ECONOMIC ASPECTS OF PROMOTABILITY, ORGANIZATION AND PUBLIC ASSISTANCE
Provedor de dados: 31
Autores: de Boer,   A.J.
The economic theory of product promotion has been developed within the framework of the theory of imperfect competition and under rather restrictive conditions. Application of these theories to rural product promotion is, in most cases, of limited value. This paper first examines some characteristics of agricultural product markets which necessitate modification of standard promotion theory. Some further complex issues in promotion theory as it relates to agricultural products are then examined. These include the stabilization of funds fOl financing promotion expenditures, promotion strategy under price discrimination schemes characteristic of several Australian primary product markets, the welfare consequences of promotion by primary producer promotion...

MULTIATTRIBUTE UTILITY THEORY, MULTIPLE OBJECTIVES AND UNCERTAINTY IN EX ANTE PROJECT EVALUATION
Provedor de dados: 31
Autores: Dillon,   John L.; Perry,   Chad.
A wide variety of methods have been suggested for ex ante project appraisal. The most logical and complete of these appears to be multiattribute utility theory (MAUT) which provides a formal procedure for handling the difficulties of ex ante evaluation arising from multiple objectives, intangibles, time-sequence effects and uncertainty. MAUT procedures, comprising an extension of subjective expected utility procedures to choice between multi attributed alternatives, are described and applied to an illustrative example.

An interregional, large-scale linear programming model is used to evaluate the economic impact of the energy crisis on U.S. agricultural production. The study examines the changes in crop production under energy minimization, an energy shortage, high energy prices, and high agricultural exports accompanied by high energy prices. Results indicate that reduced supplies or higher prices for energy will have important impacts on commodity prices, irrigated agriculture, and on rural communities.

A QUARTERLY MODEL OF THE AUSTRALIAN AGRICULTURAL SECTOR
Provedor de dados: 31
Autores: Throsby,   C.D.; Rutledge,   David J.S.
Several farm sector econometric models are reviewed initially and the aggregation problem highlighted. A thirty-equation model of the Australian agricultural sector is specified in which farm output, stocks and exports and the domestic demand for farm products are endogenous, as well as farm, export and retail prices. Disaggregation is into food and non-food components of unprocessed output, and the processing of food is traced through to final demand. The model is estimated by a modified 2SLS procedure using quarterly data covering the period 1960-1970.

MARKETING AUSTRALIAN BEEF AND EXPORT DIVERSIFICATION SCHEMES
Provedor de dados: 31
Autores: Freebairn,   John W.; Gruen,   Fred H.G.
The Australian Meat Board (AMB) can influence the quantities sent to and the prices received for Australian beef and veal in the domestic and various export markets. Through its power to grant export licences and the conditions to be met in obtaining export licences the AMB can adopt the role of a price discriminating monopolist without supply control. This paper evaluates the price, quantity, efficiency and distribution effects of the export diversification scheme introduced by the AMB in 1968, of some modified schemes proposed in 1976, and of an alternative system whereby rights to export to premium export markets with quota restrictions are auctioned.

DETERMINING OPTIMAL FERTILIZATION RATES UNDER VARIABLE WEATHER CONDITIONS
Provedor de dados: 31
Autores: Talpaz,   Hovav; Taylor,   C. Robert.
This paper presents a theoretical framework for incorporating the following sources of risk into the determination of optimal fertilization rates: (a) the influence of weather and other stochastic factors on the marginal product of fertilizer, and (b) uncertainty about the coefficients of the response function. The decision criterion considered is the maximization of profit subject to a risk constraint on the probability of not recovering the cost of the fertilizer. The theoretical framework is applied to the fertilization of dryland grain sorghum in the Texas Blacklands. Results indicate that the risk averse producer should substantially lower his fertilization rate if soil moisture at fertilization time is low.

Autores: Woodfield,   Alan; Cowie,   Don.
This paper uses observations on visitation rates to estimate Clawson demand functions for a non-priced recreation commodity, namely, the Milford Track located in the Fiordland National Park of New Zealand. Different classes of user with potentially different demand elasticities are identified, and shadow prices consistent with revenue maximization of a discriminating and non-discriminatory monopolist tourist authority are estimated. Alternative maximum revenue and consumers' surplus valuations are presented which correspond to different concepts of measures of willingness to pay for use, including travel costs and the opportunity cost of time.

THE ECONOMIC IMPACT OF FREE LYSINE ON THE PROTEIN FEEDS INDUSTRY IN N.S.W.
Provedor de dados: 31
Autores: Godden,   David P.; Batterham,   E.S.
Free lysine, an amino acid produced industrially by microbial fermentation, is becoming increasingly important in intensive livestock production. Estimates are made of the economic impact of its wider use. The economic impact of doubling the current utilization rate of free lysine in pig production is also investigated. It is shown that the use of free lysine as a replacement for protein concentrates is marginally profitable at current utilization rates and prices. However, if experimental techniques of doubling free lysine utilization rates are adopted by the industry, the use of free lysine could lower costs of pig diets and substantially replace high lysine protein concentrates in pig diets.

IMPROVED SYSTEMS OF RICE FARMING IN ZAIRE:  A COMPARISON OF UPLAND AND IRRIGATED RICE
Provedor de dados: 31
Autores: Kamuanga,   Mulumba.
Cassava, maize, rice, groundnuts and plantains constitute the main food crops in Zaire.  Rice is a staple food in several regions though its consumption has thus been concentrated in the urban centers.  The Department of Agriculture had estimated that rice consumption increased at an annual rate of 2.1 percent for the 1971-74 period and it has also predicted that this rate may reach 9.1 percent by the end of the decade.  One of Zaire's key problems is to meet its domestic demand for rice. The government policy of fixing annual hectarage targets for rice and other crops to be achieved through the opening of new land and through exhorting farmers to grow more rice has not succeeded in closing the gap between supply and demand. The focus now is on development...

SUPPLY AND DEMAND STABILIZATION AND ECONOMIC WELFARE IN AGRICULTURE: SOME DYNAMIC CONSIDERATIONS
Provedor de dados: 31
Autores: Wolanowski,   A.M.; Strong,   S.M.
Much previous work on agricultural stabilization has emphasized price stabilization. Stabilization is given a different meaning here. Additive error terms are attached to linear supply and demand functions, and the effects on consumers' and producers' surpluses of reducing these error terms are studied. That is, the error terms are assumed to have their variances reduced, and the expected values of the surpluses are derived and compared with their expected values corresponding to the original error term variances. The results are not favourable, and suggest that, with the particular criterion used here, stabilization of supply and demand functions is not as desirable as generally believed. Further results, allowing for shifts in the functions and the...

ESTIMATION OF A PRODUCTION FRONTIER MODEL: WITH APPLICATION TO THE PASTORAL ZONE OF EASTERN AUSTRALIA
Provedor de dados: 31
Autores: Battese,   George E.; Corra,   Greg S.
This paper considers a statistical model for a production frontier that is consistent with the traditional (nonstochastic) definition of a production function given in microeconomic theory. Limiting cases of the model are the familiar average production function and an envelope production function. Maximum-likelihood estimators for the parameters of the model are defined. The three related models are applied in the estimation of a production frontier for the Pastoral Zone of Eastern Australia with use of data from the Australian Grazing Industry Survey.

Economic Impact of Flooding on Agricultural Production in Northeast Central North Dakota
Provedor de dados: 31
Autores: Leitch,   Jay A.; Scott,   Donald F.
The Devils Lake Basin is a closed basin in which a number of damaging floods have been recorded in recent decades. Flooding occurs in the spring as a result of snowmelt and in the summer as a result of severe summer rainstorms. The main flood problem in the Basin is damage to agricultural land and crops. This report presents a procedure for estimating flood damages in the Basin and preliminary flood damage estimates are given. Also included are selected statistics on wetland and drainage in the Devils Lake Basin.

ESTIMATES OF COST FUNCTIONS FOR PRIMARY SCHOOLS IN RURAL AREAS
Provedor de dados: 31
Autores: Hind,   Ian W.
Rural depopulation has put in question the economic viability of many rural institutions. This paper discusses a number of the important conceptual issues that need to be considered when examining the economics of one group of rural institutions, namely schools. Measurement of educational output in particular is fraught with many difficulties. The paper then presents some estimates of cost functions for primary schools in rural areas of New South Wales. The approach combines conventional statistical methods of deriving cost functions with synthetic procedures based on the technology of schooling. It is found that economies and diseconomies of size do exist with respect to certain costs, but it is not clear whether savings can be realized from consolidation...

The "best" use of natural resources -- using them where they are needed the most and can provide the greatest return to society with respect to economic, political, and environmental standards -- is a basic question facing our society.  It is a question that has received more and more attention in recent years, as an acute awareness of ecological problems has developed in the industrialized portion of the world.  The problem has also become more complex as more and more natural resources are subjected to more intensive multiple uses.  Conflicts arise between the users of such resources when the actions of one user encroach upon the use of the resource by another.  Usually such conflicts can only be resolved by limiting one or more uses.  In the case of...

SOFT WHITE AND SOFT RED WHEAT PRODUCTION AND MARKETING IN MICHIGAN:  IMPORTANCE SUPPLY, DEMAND, PRICE BEHAVIOR, AND FUTURES MARKET RELATIONSHIPS
Provedor de dados: 31
Autores: Carman,   Garth A.
Many different classes of wheat are grown in Michigan's agriculture sector but only two types of wheat are grown to any significant degree.  Easily the most dominant type of wheat grown is soft white wheat which is a sub-class of white wheat.  The other class of wheat grown in Michigan is soft red wheat.  Since these two wheat crops comprise consistently over 90% of the wheat acreage in Michigan this analysis will only be concerned with them.  The purpose of this study is to examine the trade-offs in producing and marketing soft white and soft red wheat in Michigan for the purpose of identifying optimal strategies for the participants.  The uses of both types of wheat will be examined as well as the impact of new technology on the substitutability of soft...

A LINEAR PROGRAMMING ANALYSIS OF THE EMPLOYMENT, INCOME AND PRODUCTIVITY OF THE SMALL FARM AND RICE PROCESSING SECTORS OF SIERRA LEONE
Provedor de dados: 31
Autores: Rose,   Frank S.
Agriculture is the largest sector in the economy of Sierra Leone, employing approximately 75 percent of the population in 1972 and accounting for over 30 percent of the gross domestic product.  But though the national economy has grown at an estimated 4.3  percent rate in the last decade, the agricultural sector is estimated to have grown only 1.6 percent per year.  The government of Sierra Leone, recognizing the importance of the agricultural sector and the need to develop policies to encourage its growth, has set a goal of increasing the growth rate of the sector to 4.6 percent per annum.  Central to the overall agricultural development plan is the emphasis on increased rice production.  Rice is the staple food in Sierra Leone, grown by over 80 percent...

OPTIMAL GROWTH STRATEGIES FOR PASTORAL FIRMS IN THE QUEENSLAND BRIGALOW SCHEME
Provedor de dados: 31
Autores: Harrison,   Stephen R.; Longworth,   John W.
The Brigalow Scheme has been one of Australia's largest dryland development projects since World War II. Large sums of private and public capital have been invested to create 247 new farm firms. Planning the development of these new properties is a complex task. A simulation model of the typical block in Area III of the Brigalow Scheme has been constructed and used to evaluate experimentally the financial performance of various growth strategies. Use of a conjugate directions search procedure with this model has allowed growth strategies to be identified which maximize net worth subject to a low risk of financial failure. These strategies are compared with development programmes which have already been implemented. Significant conclusions are reached both...

A NOTE ON OFF-FARM INCOME OF FARM FAMILIES IN AUSTRALIA
Provedor de dados: 31
Autores: Tubman,   Wendy.
Past studies of the farm sector have concentrated on the use of farm based resources in the farm context alone. Changes in the economic environment have widened the opportunities available to these resources and have thus tended to make this narrow definition of the farm firm less relevant. Some recognition of this situation has emerged in more recent studies. The aim of this note is to collate and examine the degree to which farm labour resources are employed in off-farm activities in Australia. The main conclusion drawn from the evidence available is that, while in aggregate part-time farming is a fairly minor activity, in some sectors it is increasing in importance and constitutes a considerable outlet for farm based labour resources.

MODELING FLUID MILK SUPPLY AND DEMAND WITH PROJECTIONS TO 1985
Provedor de dados: 31
Autores: Rawson,   Edward M.
The intent of this study is to develop a model which represents the supply and demand relationships for fluid milk in the United States in order to forecast farm prices and the level of milk production for 1975 and to make projections to 1985 of the domestic consumption of fluid milk.  The concept of a polynomial lag formulation of milk production is combined with the use of gross margins in an attempt to more adequately reflect the impact of biological factors and other apriori information on production response to price changes.  A literature review traces the work of other authors pertinent to the development of a methodology for this study, including some of the theoretical drawbacks to the use of polynomial lags.  A section on methodology relates a...

PROTECTION STRATEGIES FOR AUSTRALIA
Provedor de dados: 31
Autores: Edwards,   Geoff W.
The Industries Assistance Commission and the Green Paper on Rural Policy support different protection strategies. Both strategies allow the achievement of a pattern of protection consistent with Pareto-efficiency. The Green Paper on Manufacturing proposed an approach to tariffs that would perpetuate inefficient resource allocation. The argument of the lAC and the Green Papers on protection policy is examined. A programme of across the board reductions in protection leading to free trade, modified for terms of trade effects, is suggested. It is also argued that initial increases in assistance for low cost industries are not inconsistent with such a programme.

This paper reports on a preliminary study which aimed to determine whether a proposed pig carcase description scheme could be regarded as appropriate for the needs of market participants in the Australian pig market. Regression techniques applied to carcase measurements and cut-out data revealed that those carcase characteristics used as the basis of the description scheme significantly explained wholesale and retail carcase values. Available evidence also suggests that market participants are using this measurement information in their trading activities.

NATIONAL INCOME AND EMPLOYMENT IMPACTS OF RAILROAD BRANCH LINE ABANDONMENT:  CONCEPTUALIZATION AND MEASUREMENT
Provedor de dados: 31
Autores: Fishbein,   Robert Eric.
This study seeks to contribute to the development of procedures which provide useful information to decision-makers and affected people regarding the national income and employment impacts of railroad branch line abandonment.  There are three major parts to this paper.  The first part probes the underlying assumptions of public investment analysis.  It is noted that non-Pareto optimal welfare changes occur whether or not abandonment takes place.  The decision of whether or not to subsidize branch lines is based on the decision-makers' evaluation of certain important consequences, expressed in terms of criterion variables.  It is argued that analyses should provide information regarding criterion variables to which decision-makers can assign values in the...

DETERMINANTS OF MARKETED SURPLUS IN RURAL HOUSEHOLDS:  TOWARD AN APPLIED RESEARCH AGENDA FROM AN AFRICAN POLICY PERSPECTIVE
Provedor de dados: 31
Autores: Newman,   Mark D.
African governments are increasingly interested in understanding factors affecting the marketing of staple food grains by rural households which produce partially for home consumption.  Food security depends not only on aggregate production, but also the distribution of production by income group, social class and geographical area.  The availability of food to nonagricultural producers and those who produce insufficient amounts to satisfy their subsistence requirements is influenced by the interaction of variables affecting the allocation of production between sales and other disposals, consumption, and storage.  Grain which is added to disposals limits household consumption as well as security provided by on-farm stocks.  At the same time, if sold, it...

DISTRIBUTIONS OF INDEMNITIES FOR CROP-INSURANCE PLANS: WITH APPLICATION TO GRAIN CROPS IN NEW SOUTH WALES
Provedor de dados: 31
Autores: Battese,   George E.; Francisco,   Emilio M.
A review of crop-insurance schemes is followed by a discussion of a guaranteed-yield, crop-insurance plan. General formulae for the distribution function and mathematical expectation of indemnities for the insurance plan are presented in terms of the distribution of crop yields. Three special cases are considered in which the original yields, the square root of yields, and the logarithm of yields are normally distributed.  The insurance plan is applied on a regional basis for wheat and sorghum production in N.S.W. Given distributional information on the crops obtained from a simulation model, expected indemnities are calculated for four different insurance plans.

SUPPLY RESPONSE TO RISK:  THE CASE OF U.S. PINTO BEANS
Provedor de dados: 31
Autores: Ryan,   Timothy J.
A standard model of behavior  under uncertainty is used to suggest price risk variables for use in a positive supply study. The suggested variables are intuitively appealing and empirically tested on Pinto bean data. Linearity is assumed and O.L.S. used. The empirical results show that the risk variables greatly improve the statistical fit of the supply equation, are quantitatively important and that a substantial bias occurs if they are neglected. Policy initiatives to reduce Pinto bean price fluctuations need to consider the risk reducing effects on the supply response.

THE POTENTIAL IMPACT OF AIRLINE DEREGULATION ON FEEDER ROUTES IN THE FAR WEST
Provedor de dados: 31
Autores: Shepard,   Lawrence.
In anticipation of the air transportation regulatory reform act, this paper assesses the consequences of deregulating the airline industry. Particular attention is devoted to the impact of deregulation on air fares, travel demand, and flight frequency for relatively short feeder routes connecting small cities and rural centers. On the basis of a sample of routes in the far western states, it appears that deregulation would raise fares on routes shorter than 100 miles while lowering prices on longer trunk routes connecting major metropolitan areas. Flight frequency on particular routes would be curtailed by approximately 28 percent as airlines substituted price competition for non-price rivalry under a new regulatory regime.

A PERSONAL VIEW OF THE ROLE OF THE GOVERNMENT IN THE DOMINICAN FOOD AND FIBER SYSTEM
Provedor de dados: 31
Autores: Diaz,   Joaquin A.
The Dominican government is currently undertaking many programs in the food and fiber sector which are expected to improve agricultural sector performance which in turn is important for the development of the whole economy.  Thus, it is important to identify the general strengths and weaknesses of the system "as is" in order to carefully select subsequent specific studies about the Dominican food and fiber system.  Although this study is general, it is nonetheless valuable since it contributes to a basic and introductory understanding of the Dominican case.  The main objective of this study is to describe the general role that the government might play in the Dominican food and fiber sector in order to obtain more efficiency and equity among the systems'...

A STOCHASTIC MODEL FOR THE OPTIMAL REPLACEMENT OF RUBBER TREES
Provedor de dados: 31
Autores: Etherington,   Dan M.
Recognizing the lack of realism in optimal replacement analyses that assume constant prices and yield patterns over time, a stochastic model appropriate to rubber production is developed. Data drawn from Peninsular Malaysia are used to implement the model. The results suggest that efforts should be directed towards establishing bench mark maximum annuities as guides to more economic replanting decisions rather than emphasizing earlier replanting per se. The significance of price stabilization policies also becomes evident.

Autores: Battese,   George E.
The significance of statistical lack-of-fit tests for hypothesized response functions describing experimental data is traced in some of the recent agricultural economics literature. The statistical test is reviewed in a regression framework and it is shown that the test is related to testing that some of the coefficients in a linear regression model have zero values. Comments are made on the relationship between the lack-of-fit test and the coefficient of determination.

The need for this study stems from the problems of grain shortage in these parts of the world.  The regions included in this study are:  North Africa (Morocco, Algeria, Tunisia, Libya, United Arab Republic and Sudan), Ethiopia, Kenya, Nigeria, and the Republic of South Africa.  The North Africa region was chosen to conform with previous analysis which was done on the demand side in a project of the Department of Agricultural Economics of Michigan State University.  Other countries were also included in order to make the analysis comparable to the demand study.  The methodology was basically determined by the data available.  Therefore, an analysis on existing time series data was undertaken.  It is not the purpose here to examine specific policies, but...

WINE CONSUMPTION AND IMPORTS
Provedor de dados: 31
Autores: Shea,   Patrick T.
There are four major types of wine:  table wine, dessert wine, sparkling wines and champagnes, and vermouth.  Greatest attention is focused upon table wines because of the prominent role they have come to play in the industry.  In 1960, only 30% of all wine consumed in the U.S. was table wine.  By 1970, this percentage had grown to 50 and by 1980 it is expected that 80% of U.S. wine consumption will be of this type.

THE MARKETING STRUCTURE AND PERFORMANCE OF THE OLIVE OIL INDUSTRY IN TUNISIA
Provedor de dados: 31
Autores: Abdelkafi,   Belhassen.
In terms of value added, olive oil is one of the most important agricultural commodities in Tunisia.  It is also the most important agricultural export commodity.  Tunisia ranks second to Spain in world olive oil exports.  Currently these exports account for about 20 percent of total export earnings of Tunisia.  This is equivalent to about 40 percent of total agricultural export earnings.  Tunisia is by far the largest olive oil producing country in North Africa and the Middle East and ranks sixth among the world's producers of olive oil.  Considering the adaptability of the olive tree to the climate and soil conditions of Tunisia, olive culture is expected to maintain its importance in Tunisian agriculture.  However, the economic benefits which could be...

CHARACTERISTICS OF THE MILK PRODUCTION SUBSECTOR AND SUPPLY RESPONSE OF DAIRY PRODUCERS TO GOVERNMENT POLICIES AND MARKET CONDITIONS IN COLOMBIA, SOUTH AMERICA
Provedor de dados: 31
Autores: Meza,   Ernesto Rincon.
During the last decade there has been increasing concern in Colombia with respect to the inability of the dairy production industry to respond in the short run to the internal demand for milk, with greater volumes and improved quality of the product.  This situation has become evident by the low level of consumption of milk estimated to be 73.4 liter of milk/person/year by the National Institute of Welfare, far below the normal requirement estimated to be 143 liter/person/year.  This situation seems to be aggravated by the trend in the population growth in already populated consumption centers, the low purchasing power of the low income groups, and the slow increment in milk production.  However, and in spite of, the governments effort to close the gap...

Restrictions on input use frequently accompany the granting of institutional credit to farmers in developing agriculture. A general economic framework is suggested to analyze the net social benefits of such a policy. The paper discusses the potential for manipulating the policy variables to foster more rapid adoption of new agricultural technology. An empirical analysis of the impact of a supervised credit programme in Guatemala on farm performance and farmer decision-making is presented.

Autores: Visscher,   Jack E.
Land use policy unquestionably requires information about land ownership.  During the Congressional debate on the Land Use Policy and Planning Assistance Act of 1972, Senator Henry Jackson of Washington recognized the need for land ownership information when he said:  "Rational land use planning would be impossible without knowledge of patterns of land ownership within a given area."  (1)  Yet this information is not generally available for the planning process.  Senator Jackson also said:  "It seems not only probable, but inevitable that, among the many other benefits of this legislation, the country may expect to obtain fairly soon a system of identifying and classifying the ownership and control of land..."  (2)  His prediction has not come to pass....

OPTIMUM PLANS OF FARM PRODUCTION FOR THE REGION OF MANI, GREECE
Provedor de dados: 31
Autores: Stamatoukos,   George Evangelou.
The major problem in rural Greece is it depopulation.  From 1961 to 1971 the urban population of Greece increased from 43.3 to 53.2 percent, while at the same time its rural population decreased from 43.8 to 35.1 percent.  This movement away from farming has reached very high levels in some poor and distant regions of the country.  Mani, located on the extreme southern part of continental Greece, is such a region.  The urbanization movement, resulting mainly from the lower returns to labor employed in farming, as compared to that employed in most non-farm occupations and from the centralization of industry in the bigger urban centers has resulted in accumulating population near Athens and Salonica, (in 1971, the population of Athens proper was 29.0 percent...

ENERGY ANALYSIS METHODS IN AGRICULTURAL PRODUCTION WITH APPLICATIONS TO CHIANG MAI VALLEY, THAILAND
Provedor de dados: 31
Autores: Chareodrat,   Pimpan.
Population increased and land became scarce.  In the mid 1980's, the earth's population is expected to reach the five billion level rising to six billion well before the year 2000.  The rate of population growth indicates that the world's food requirement will present a shortage problem.  Food production is lagging behind population growth.  Problems of feeding the rapidly increasing world population includes requirements for irrigation and fertilizer products which in turn require large amounts of energy input.  The interrelationship of energy and human members can be better appreciated when it is recognized that energy use has been increasing faster than the world population.  The world doubled its energy consumption within the past decade while the...

Resumo Em abril de 1977 ocorreu um surto de malária falciparum nas Tribos Sanomã e Mayongong, em Roraima, na fronteira do Brasil e Venezuela. Duzentos e sessenta e oitc silvícolas foram examinados para malária e 91 casos foram positivos, dois para Plasmodium vivax e 89 para Plasmodium falciparum. O vetor responsável pela epidemia foi o Anopheles darlingi com uma atividade média de 64 picadas/homem por noite. Três casos de falciparum foram resistentes às cloroquinas. respondendo favoravelmente ao Fansidar (sulfadoxina e pirimetamina). Houve diferença distinta nas duas tribos baseada na proximidade da população do vetor. Essas diferenças foram apresentadas por idade e sexo. Foi interessante a descoberta de um grupo de Sanomã que, no esforço para livrar-se ao...

Aspectos do problema das cáries dentárias no Estado do Amazonas
Provedor de dados: 36
Autores: Shrimpton,Roger; Giugliano,Rodolfo.
Resumo São apresentados dados sobre a incidência de cáries em 193 crianças pobres de 1 a 8 anos de idade em Manaus, Amazonas, 1976. A incidência de cáries foi de 77,7%, sendo que no grupo etário de 8 anos atingiu a 97,9%. Possíveis fatores locais envolvidos na evolução das cáries e as possíveis medidas a serem tomadas são discutidos. São enfatizadas a inapropriedade do tratamento dentário conservador e a essencialidade de medidas preventivas nesta área tão grande mas esparsamente povoada. A promoção da amamentação sobre a alimentação artificial nas primeiras semanas de vida da criança e a fluoretação do sal, são sugeridas como medidas práticas de mínimo custo e máximo alcance na redução das cáries em populações rurais e urbanas da Bacia Amazônica.

Differences in stomatal number per unit area within the same species under different micro-environmental conditions: A working hypothesis
Provedor de dados: 36
Autores: Lleras,Eduardo.
Abstract A summary of Salisbury's (1927) work on stomata is presented here. He found, basically, that the number of stomata per unit area increased under more xerophytic conditions. This is contrary to prevalent opinion, that postulates that under more humid conditions, the number of stomata can be greater, as there is less danger of dehydration. A hypothesis is presented here that can explain this: The more xerophytic the conditions, the higher the number of stomata per unit area to permit more efficient gas interchange at those times when relative humidity is high, and danger of excessive dehydration is lowest.

Nota preliminar sobre a origem das campinas abertas de areia branca do baixo Rio Negro
Provedor de dados: 36
Autores: Prance,Ghillean T.; Schubart,Herbert O. R.
Summary The origins of the open areas of white sand campinas of the lower rio Negro is discussed. Campinas are compared with the denser campina forests or caatingas of the upper rio Negro. It is concluded that the campinas are areas of white sand forest cleared by Indians. Evidence from pottery shards and radiocarbon dating of charcoal deposited in the soil demonstrates that the campinas were occupied by Indians of the Guarita subtradition around 800 A.D. The open campina areas show a gradual sucession to more closed type of campina to campina forest, the climax on the white sand. Recolonization after Indian clearing is extremely slow on white sand because of limiting factors such as nutrients and excessive drainage in the dry season.

Autores: Conceição,Pedro Nonato da.
Resumo Neste trabalho, foram medidos os parâmetros ecofisiológicos de algumas espécies de mata tropical pluvial de terra firme. Os dados obtidos foram correlacionados com as descrições de tipos de solo de Falesi et al. (1969) e com o inventário da área de estudo feito por Prance et al. (1975). Os parâmetros considerados foram luz, ponto de compensação de luz, comportamento dos estômatos das espécies do estrato mais inferior da mata e em relação ao deficit de água e ao enrugamento e intumescimento dos troncos de algumas espécies da mata.

Autores: Reis,Carlos Moura dos; Tancredi,Antonio Carlos F. N. S.; Matsui,Eiichi; Salati,Enéas.
Resumo Às pesquisas hidrológicas convencionais executadas pelo IDESP na região do arquipélago de Marajó, foi associado o estudo das variações naturais dos isótopos de hidrogênio e oxigênio das águas. Foram realizadas medidas das concentrações de Deutério e Oxigênio-18 em águas de precipitação, de rios, de lagos do interior da ilha de Marajó e das águas superficiais circundantes da mesma. Os dados obtidos são discutidos no que concerne à aplicabilidade dessas técnicas aos estudos hidrológicos da região de Marajó. A diferença de composição isotópica entre as águas do rio Amazonas na orla norte e as águas da baía de Marajó na orla sul aparece nitidamente, não obstante o aporte de águas do rio Amazonas para a baía de Marajó detectado através das análises...

Gecropia purpurascens, a new species for Brazilian Amazonia
Provedor de dados: 36
Autores: Berg,C. C.
Abstract A new species of Cecropia, C. purpurascens C.C. Berg is described. Although it is common in the vicinity of Manaus, it has been overlooked previously because Cecropia is still a poorly studied genus. This new species is quite distinct from related species and is inhabited by ants of the genus Azteca.

Leishmanias of Neotropical Porcupines: Leishmania hertigi deanei nov. subsp.
Provedor de dados: 36
Autores: Lainson,R.; Shaw,J. J.
Abstract A leishmanial parasite was isolated from 11 of 18 porcupines from the general area of Ponta de Pedras, Island of Marajó, Pará State, north Brazil. Two of the infected animals were identified as Coendou prehensilis (Linnaeus), and the other 9 are considered as a hitherto undescribed species of Coendou. The organism is clearly related to L. hertigi Herrer, of the Panamanian porcupine C. rothschildi Thomas, but morphological, serological and biochemical differences necessitate taxonomic distinction. The Brazilian parasite is therefore named Leishmania hertigi deanei nov. subsp., in honour of Dr. Leonidas Deane who first recorded it in porcupines from Piaui, Brazil. Lake L. h. hertigi, L. h. deanei produces no visible pathological effects in its...

Flebótomos da Amazônia Central do Brasil. I. Resultados obtidos das capturas feitas com iscas humana e eqüina (Diptera, Psychodidae)
Provedor de dados: 36
Autores: Arias,Jorge R.; Freitas,Rui A. de.
Resumo Capturas de flebótomos com isca humana e isca eqüina foram realizadas numa floresta tropical na Amazônia Central do Brasil. Todos os flebótomos que atacam ao homem, com a exceção de Lutzomyia punctigeniculata (Floch &amp; Âbonnenc), também atacam cavalos; algumas outras espécies atacam cavalos mas não sugam sangue humano. Descobrimos portanto, que, quando se está procurando as espécies antropofílicas da região, um homem pode ser substituído por um cavalo. A espécie que mais freqüentemente ataca o homem é L. maripaensis (Floch &amp; Abonnenc), e esta foi também a espécie que mais freqüentemente atacou o cavalo. O flebótomo capturado mais freqüentemente atacando o homem, a 15m acima do chão da floresta, foi L. anduzei (Floch &amp; Abonnenc). Um total...

Autores: Shrimpton,Roger; Giugliano,Rodolfo.
Resumo O estado nutricional, padrões alimentares, infecções intestinais e respiratórias foram verificados em 82 crianças no primeiro ano de vida de uma população urbana de Manaus Amazonas, nos meses de maio e junho de 1976. Alto índice de desnutrição acompanhado de alta morbilidade foi encontrado. Constatou-se também alta taxa de recém-nascidos de baixo peso, sugerindo uma freqüência elevada de desnutrição intra-útero. Os fatores predisponentes mais importantes foram atribuídos à substituição precoce da amamentação pelo leite artificial, à falta de orientação ou orientação errônea das mães compreendendo a ausência total de uma puericultura dirigida às condições sócio-econômicas da região.

Os nomes e usos de palmeiras entre uma tribo de índios Yanomama
Provedor de dados: 36
Autores: Anderson,Anthony B.
Resumo Referências sobre 20 principais espécies de palmeiras utilizadas pelos Xiriana-teri, uma tribo de índios Yanomama, localizada ao norte do Estado do Amazonas, Brasil. Os nomes comuns (indígenas e brasileiros) e científicos de cada espécie são mencionados. Os usos que os Xiriana-teri fazem das palmeiras são examinados detalhadamente, concluindo-se que eles as utilizam em grau muito menor do que outras tribos de diversas regiões tropicais da América do Sul. Em grande parte, isso é devido aos aspectos materiais de sua cultura, bastante rudimentares em relação a outras tribos. Também, segundo observações do autor, houve no passado uma superexploração de espécies economicamente importantes nas proximidades da aldeia, o que é um fator importante na...

Autores: Lleras,Eduardo; Diaz,Aura M. P. de.
Resumo A anatomia foliar e a identificação química da cera cuticular da folha de uma espécie de Heliconia, afima H. tarumaensis, são apresentadas neste trabalho. A estrutura anatômica da folha é sugestiva de uma planta heliófita, o que concorda bem com os habitats conhecidos para ela. É de notar-se a presença de canais rexígenos, tanto na nervura central quanto no pecíolo. Também são interessantes as baixas proporções de tecido parenquimático, que nunca chegam a ocupar mais da metade da espessura da lâmina. A cera cuticular foi identificada como laurato de n-tetracosila em sua totalidade.

Autores: Castro,Paulo R.C.; Duarte,Maria L.R.; Machado,Carlos C.; Castro,Carlos; Brito,Antonio S.
A importância do estudo do potencial osmótico das plantas deve-se ao fato deste parâmetro ser considerado o principal componente do potencial hídrico, refletindo o equilíbrio de água na planta. Determinou-se o potencial osmótico foliar do tomateiro (Lycopersicon esculentum Mill. cv. "Angela") através de osmômetro de precisão. As plantas haviam sido tratadas com cloreto de (2-cloroetil) trimetilamônio (CCC) 2000 ppm, ácido succínico-2,2-dimetilhidrazida (Alar) 3000 ppm e giberelato de potássio (Gibrel) 100 ppm, além do controle. Verificou-se que o Gibrel promoveu uma redução no potencial osmótico; sendo que Alar provocou flutuações no potencial do tomateiro "Angela". O CCC causou maior equilíbrio no potencial osmótico foliar do tomateiro. Observou-se que as...

Autores: Accorsi,Walter Radames; Barros,Myrthes A.S. de.
Resumimos, neste trabalho, os resultados das observações sobre a adaptação fenotípica de raízes de várias plantas, tais como grama-batatais - Paspalum notatum, quebra-pedra ou erva-pombinha Phyllathus ninuri, maria-preta - Solanum nigrum, carurú - Amaranthus sp., tiririca - Cyperus rotundus e outras, com os frutos encontrados no solo da palmeira Dictyosperma rubra Wendl. &amp;amp; Drude, cultivada como ornamental no Parque da Escola Superior de Agricultura "Luiz de Queiroz". Essa adaptação caracteriza-se pela penetração das raízes através de orifícios circulares, existentes no pericarpo dos frutos, e produzidos por uma broca da família Bostriquide, da ordem Coleoptera. As raízes assim assemelham-se a um colar. Diante desse fato, decidimos montar um...

Provedor de dados: 43
Autores: Neptune,A.M.L.; Muraoka,T.
An experiment was carried out with common bean (Phaseolus vulgaris, L.) in a Red Yellow Latossol, sandy phase, in order to study the influence of foliar spraying of the Hanway nutrient solution (NPKS) at grain filling stage on: 1) grain yield; 2) the uptake of fertilizer and soil nitrogen by this crop through the root system and 3) the efficiency of utilization of the nitrogen in the foliar spray solution by the grain. The results of this experiment showed that the foliar application of the Hanway solution with ammonium nitrate at the pod filling period caused severe leaf burn and grain yield was inferior to that of the plants which received a soil application of this fertilizer at the same stage. These facts can be attributed to the presence of ammonium...

Provedor de dados: 43
Autores: Lucchesi,Antonio A.; Florencio,Antonio C.; Minami,Keigo.
Estudou-se a influência do ácido 2-cloroetil fosfônico (Ethrel) na indução do florescimento do tomateiro, de crescimento indeterminado, cultivar "Santa Cruz Gigante", aplicado em diferentes estágios de desenvolvimento (uma, quatro e oito semanas após o transplante da planta para o campo), nas concentrações de 100, 200, 300 e 400 ppm do produto. Observou-se que em plantas em pleno florescimento, as maiores concentrações do produto (300 e 400 ppm) provocaram murchamento da planta e posterior abscisão de parte das inflorescências, sem, entretanto reduzir a produção final. Não foi observada, a indução do florescimento e também aumento significativo na produtividade final.

Autores: Nakagawa,Júlio; Neptune,A. M. Louis; Vieira,F. Roberto; Bataglia,O. Cleante.
Nos últimos trabalhos de adubação, feitos no Estado de São Paulo, com mamoneira, tem-se observado que o fósforo é o fator limitante na produção de sementes. Para observar como o fósforo atua no crescimento, na produção e nos teores de óleo e de macronutrientes nos frutos, foi realizado um ensaio de campo, utilizando-se cultivar "Campinas" e as doses de 0-40-80-120-160 e 200 kg/ha de P2O5, num solo pobre, classificado como Latossolo Vermelho Escuro - fase arenosa. Em relação ao tratamento sem fósforo, o incremento médio observado na produção de sementes foi de 320,40%. Esses aumentos foram alcançados porque o fósforo contribuiu para aumentar o número de frutos, por cacho e por parcela, diminuir a porcentagem de casca no fruto e aumentar o peso de sementes...

Foi estudado por espectrografia de raio X a distribuição do Ca e K na fração areia e no solo total em oito pedons representativos de uma topossequência de solos da região de São Pedro no Estado de São Paulo. As principais conclusões foram as seguintes: - Com exceção dos Pedons 1 e 3 os teores de K e Ca são muito baixos. Os elevados teores de K encontrados nos Pedons 1 e 3 indicam que os materiais das superfícies I e III são menos intemperizados e portanto de origem mais recente. - A fração areia dos solos estudados, com exceção dos Pedons 1 e 3, possue baixíssimos valores de K e Ca, consequentemente de minerais contendo tais elementos. - Com exceção do Pedon 3 os solos não possuem reserva mineral na fração areia. - De todos os solos estudados os Pedons 6,...

Qualidade da bebida do café: efeito do acondicionamento e do tempo de conservação
Provedor de dados: 53
Autores: Teixeira,A. A.; Fazuoli,L. C.; Carvalho,A.
O efeito do tempo de armazenamento sobre a qualidade da bebida de café do cultivar mundo novo de Coffea arabica foi estudado em Campinas, no período de junho de 1974 a março de 1976. Planejou-se o delineamento em blocos ao acaso para as amostras, sendo analisada a bebida do café despolpado e beneficiado conservado em latas hermeticamente fechadas, em sacos de plástico, de aniagem, de tecido de algodão e de papel. Para os testes de bebida adotou-se o delineamento de blocos ao acaso. Três séries de amostras foram retiradas 5, 16 e 21 meses, após o inicio do experimento e analisadas quanto à qualidade da bebida, usando-se a escala de 0-5 pontos, normalmente empregada para essas avaliações. Não se notaram efeitos de embalagem nas amostras analisadas na...

Autores: Pommer,Celso Valdevino; Miranda,Luiz Torres de; Miranda,Luiz Eugênio Coelho de; Sawazaki,Eduardo.
Através dos testes de progênies realizados para o melhoramento da população de milho IAC-1 opaco-2 obtiveram-se estimativas de uma série de parâmetros genéticos. As estimativas obtidas para variância entre progênies de meios-irmãos, coeficiente de variação genética e variância genética aditiva permitem concluir que a população deve continuar reagindo favoravelmente à seleção. As estimativas do progresso esperado na seleção foram bastante próximas do progresso real calculado, mostrando grande eficiência da metodologia empregada. As estimativas de parâmetros genéticos no IAC-1 opaco-2 mostraram ser de grande valia para a apreciação do processo de seleção nessa população permitindo, inclusive, predições seguras a respeito do progresso genético a ser obtido.

Provedor de dados: 53
Autores: Van Raij,Bernardo.
São apresentados dados do poder relativo de neutralização total (PRNT) de calcários utilizados como corretivos do solo no Estado de São Paulo. O PRNT é uma medida da eficiência dos calcários que conjuga o poder de neutralização total com a eficiência relativa de partículas de diferentes tamanhos. No trabalho é proposto o cálculo do PRNT com utilização dos teores de cálcio e magnésio e a distribuição granulométrica determinada apenas com as peneiras 10 e 50. Os resultados de PRNT das 25 amostras de calcários analisadas variaram de 52,3 a 93,8% de CaCO3 equivalente, com um valor médio de 66,9%.

Autores: Pedro Júnior,Mário J.; Brunini,Orivaldo; Alfonsi,Rogério Remo; Angelocci,Luiz Roberto.
O grau-dia é uma unidade térmica utilizada, principalmente, na determinação de épocas de plantio e colheita dos vegetais, contribuindo para uma agricultura racional. Pode ser estimado através de dados termométricos, ou seja, de médias mensais de temperaturas máximas e mínimas, obtidas em abrigos meteorológicos padrões, para regiões climaticamente homogêneas. No presente trabalho foi utilizada a temperatura base de 10° C, abaixo da qual grande parte das plantas anuais não têm bom desenvolvimento. Devido à pequena quantidade de estações meteorológicas no Estado, determinaram-se equações de regressão múltipla, pelo método dos quadrados mínimos, para a estimativa do total mensal de graus-dia em função da altitude e latitude da localidade.

Provedor de dados: 53
Autores: Miranda,Luiz Torres de; Miranda,Luiz Eugênio Coelho de; Pommer,Celso Valdevino; Sawazaki,Eduardo.
São relatados os resultados obtidos em oito ciclos de seleção entre e dentro de famílias de meios irmãos numa população de milho, o IAC-1. Para produção de grãos foi observado um progresso genético médio de 1,9% por ciclo, comparado com um progresso genético esperado de 8,8% por ciclo. Para índice-de-espigas foi estimado um progresso genético esperado de 1,5% por ciclo aplicando-se os mesmos diferenciais de seleção utilizados para produção. Entretanto, não foi feita seleção sistemática entre progênies para este caráter. A porcentagem de plantas acamadas e quebradas não se alterou profundamente no decorrer dos ciclos de seleção. Houve um melhoramento real na população.

A absorção de macronutrientes e de silício e o acúmulo de matéria seca em três estádios de desenvolvimento de dois híbridos simples de milho, cultivados em duas densidades de população, foram estudados no presente trabalho. Verificou-se que o híbrido HS 1227 apresentou concentrações mais elevadas de fósforo, potássio e silício do que o HS 7777. Observou-se também que as concentrações dos elementos tornaram-se mais baixas em função da idade das plantas. O híbrido HS 7777 absorveu maiores quantidades de cálcio, e no espaçamento menor, para os dois cultivares, a extração de nutrientes foi maior. As taxas diárias de absorção dos nutrientes e de acúmulo de matéria seca foram mais elevadas no período compreendido entre 29 e 42 dias da germinação, isto é, do...

Analisaram-se as características da bebida de alguns cafeeiros híbridos (Coffea arabica x C. canephora) que deram origem ao icatu, e de plantas pertencentes a nove populações deste cultivar. A qualidade da bebida dos cafeeiros originais mostrou-se semelhante à do arábica, variando de "mole" a "apenas mole". Nas populações de icatu foram efetuadas 1953 determinações. Verificou-se que a bebida não difere daquela produzida pelo cultivar acaiá (C. arabica), tomada como padrão. Em escala de cinco pontos, 63 (3,2%) determinações deram bebida "dura" e 1324 (67,8%), "mole", enquanto o acaiá apresentou bebida "mole". Na escala de 10 pontos o número 3 foi dado a nove determinações (0,5%) e o máximo de nove pontos a 677 (34,6%), sendo de 7,7 a média de pontos...

Foram conduzidos estudos em vasos e no campo, para conhecer até que profundidade ocorria germinação de capim-carrapicho (Cenchrus echinatus L.). Em vasos esta ocorreu até 11 cm de profundidade e no campo até 9 cm em solo argiloso, e 10 cm em solo barrento. Foi frequente a germinação de duas ou mais cariopses por infrutescência. Em dois outros testes em vasos foi estudado o local de ação do trifluralin na dose de 0,84 kg/ha de i.a., em solo barrento. Verificou-se ação do herbicida nas zonas meristemáticas da raiz e do coleóptilo, causando inibição de desenvolvimento longitudinal do mesocótilo e da raiz. Na ponta da raiz primária, no primeiro nó e nó coleoptilar verificou-se aumento pronunciado de diâmetro.

São relatados e discutidos os efeitos de colheita manual e mecânica na qualidade da fibra e do fio do algodão e a influência do beneficiamento em máquinas descaroçadoras de rolo e de serras, sendo esta última equipada para pré e pós-limpeza do algodão, especial para beneficiamento de algodão colhido mecanicamente. Os ensaios foram conduzidos no ano de 1970/71, em Araras e Paranapanema. A colheita mecânica não afetou a qualidade da fibra ou do fio, sendo inclusive superior à manual para comprimento de fibra, em Paranapanema, e para micronaire, em Araras. O beneficiamento em máquinas descaroçadoras de serras prejudicou sempre a qualidade da fibra e do fio. A característica de resistência da fibra medida pelo aparelho Pressley não foi afetada.
