O enfoque sistêmico na pesquisa de arroz.
Provedor de dados: 14
Autores: WAGNER, E.
Neste trabalho apresentam-se considerações concernentes a este último aspecto, pois tem como escopo, divulgar o que as equipes de pesquisadores do Centro Nacional de Pesquisa - Arroz e Feijão vêm desenvolvendo, no sentido não só de adotar o enfoque recomendado pela Empresa, mas, sobretudo, de melhor objetivar as atividades de pesquisa de acordo com o "modelo concentrado". Assim, são enfatizados, além da concepção sistêmico propriamente dita, o delineamento experimental e certas recomendações, julgadas importantes para a condução dos trabalhos de pesquisa de sistemas de produção em agricultura.

Ação do tucupi como coagulante do látex da seringueira estudada sob experimento em moldes estatísticos. Ficou comprovado que o tucupi, sob qualquer dos tratamentos a que foi submetido, cru ou cozido, branco ou amarelo, de cultivares mansas ou bravas, pode perfeitamente substituir o ácido acético nos seringais, não exercendo nenhum efeito depreciativo sobre a qualidade do látex coagulado.

Aptidão agrícola dos solos do Noroeste do Estado do Paraná: (interpretação do levantamento de reconhecimento de solos).
Provedor de dados: 14
Autores: LARACH, J. O. I.
O sistema de interpretação para fins agrícolas de mapas pedológicos de caráter generalizado vale-se da comparação dos solos encontrados no campo com um solo ideal, que hipoteticamente não apresentasse nenhuma restrição para uso agrícola. As características escolhidas para estabelecer esta comparação são as condições agrícolas do solo, e foram selecionadas as seguintes: 1-deficiência de fertilidade natural; 2-deficiência de água; 3-deficiência de oxigênio (excesso de água, incluindo riscos de inundação); 4-susceptibilidade à erosão; 5-impedimentos ao uso de implementos agrícolas. As condições citadas nos itens 1, 2 e 3 influenciam tanto o uso da terra como a vegetação natural e são, portanto, de natureza ecológica, enquanto que as propriedades constantes...

Quelques possibilités d'uilisation des sardines de grande taille
Provedor de dados: 5
Autores: Durand, Henri.
Depuis plusieurs années, les pêcheurs français capturent fréquemment des sardines de grande taille. Ces poissons, dont le poids individuel peut varier de 50 à 80 g, constituent parfois une portion importante des prises et ne trouvent pas preneur à l'état frais, la clientèle étant habituée à du poisson plus petit. L'industrie de la conserve n'utilise pas non plus cette matière première car l'emboîtage dans les formats traditionnels, de petite taille, entraîne une perte importante en déchets.

Autores: Cavanie, Alain.
The spectral energy distribution of sea waves is supplied four times a day by the French Meteorological Office's DsAs model using the pressure distribution over the atlantic as input. The surface-motion spectrum furnished by the model may then be used to estimate the local current spectrum near the sea bed. The present study is based on four years (1970-1974) of DSAs data for the so-called Brittany point (47"30 N. 5"W). The data correlates reasonably well with observations made from ships in the region lying between 40 - 50 N and O - 10 W (Figure 1) . . . Plotted on Weibull paper in Figure 2 are the cumulative probability values of U as calculated from the DSAs data (U is the mean of the upper third of maximum current values at a depth of 100 m).

20 samples of phytoplankton were collected by the 'Thalassa' on the Libyan and east Tunisian coast, from Nov 13th to 29th 1969. The vegetal plankton is rather poor on the whole, except in the Gulf of Gabes. Diatoms are dominant and Rhizosolenia plays a leading part. Among the Dinophyceae, the great variety of Ceratium underlines the subtropical affinities of the study area.

Marges actives : Pérou et autres exemples

Autores: Pautot, Guy.
New oceanographic data enable us to precise the geological phenomena linked to the convergence zones of two lithospheric plates. Taking into example the Peruvian continental margin, the subduction phenomenon of the Nazca plate under the South-American plate can be tackled. This subduction occurs in the domain which is immersed by seisms, volcanism, magmatism and tectonics. We present the geophysical and sedimentological data specific to the oceanic domain of the Nazca plate and follow its evolution as it reaches the Peruvian margin. Up until the Peruvian fault, the analysis is relatively easy.

Variations des caractères biométriques et des constitutants biochimiques d'une population C. gigas (Thunberg) d'un parc d'élevage du bassin de Marennes - Oléron en 1974

Autores: Gras, Marie-paule; Gras, Paul.
At the beginning of its introduction, following the massive mortality rate of 1970-1971 that struck the Portuguese oyster, Crassostrea angulata (COMPS and GRAS 1973), the oyster from the Pacific, Crassostrea gigas, displayed excellent growth in addition to exceptional hardiness and resistance to mortality. But, since 1973, in most of the farming areas, there has been a slowdown in the growth of the oysters and an at times quite pronounced decrease in their quality. It was in order to better understand their adaptation to the environment and the causes of the lowering of their growth rate and their condition that a study was undertaken in 1974, in one of the largest areas of flat cultivation of the Marennes-Oléron basin, located on the east coast of the...

Essai d'évaluation du stock de merlu du Golfe de Gascogne et du plateau celtique
Provedor de dados: 5
Autores: Guichet, Roger; Dardignac, J.
An assessment of the hake stock exploited in the Bay of Biscay and in-the Celtic Sea has been attempted. Schaefer's and Beverton-Holt's methods have been used. Due to the lack or the inadequacy of our data, a number of assumptions have been made which restrict the validity of the conclusions. Nevertheless, both methods agree in showing that a substancial increase in production (50-80 p. 100, as an order of magnitude) could be achieved by a strong reduction of fishing effort (40-60 p. 100). A still larger increase in yield p. recruit could be achieved by a mesh increase, up to 150 mm at least

La détection des pontes dans le milieu naturel : application de l'ostréographie à l'étude de la reproduction des huîtres
Provedor de dados: 5
Autores: His, Edouard.
L'activité valvaire particulière qui accompagne la ponte chez les Crassostrea sp. permet de déceler le frai de ces huîtres. La possibilité de contrôler le comportement des mollusques par ostréographie dans le milieu naturel, est mise à profit pour déterminer la date exacte du frai. Les résultats ainsi obtenus renforcent les indications fournies par les données traditionnelles des examens de maturité sexuelle et de numération de larves dans le plancton . Un exemple basé sur les observations réalisées au cours de la saison de reproduction de 1974 dans le bassin d'Arcachon le confirme.

Etude préliminaire de la maturation de l'anchois salé (Engraulis encrasicholus) et approche des problèmes liés à l'origine du poisson
Provedor de dados: 5
Autores: Kabbaj, Farida.
Nous connaissons tous le filet d’anchois qui décore salades et pizzas et qui en rehausse agréablement le goût. Ce filet provient d'anchois salés et mûris. Les méthodes de salage peuvent être quelque peu différentes, mais le principe de base reste le même. Le poisson est salé à 25 - 30 %, étété, éviscéré, embarillé en couches alternées avec du sel, puis mis sous presse pendant 4 à 18 mois afin qu'il mûrisse. Cette maturation est nécessaire car elle confère au produit des qualités organoleptiques (un goût, une flaveur et un fumet) sans lesquelles le poisson n’est pas « anchoité ».  La pratique du salage comme moyen de conservation de denrées périssables telles que le poisson remonte à des temps très anciens (Egypte ancienne et Grèce antique). Mais les hommes...

Structures géologiques de la marge continentale à l'ouest du spitzberg
Provedor de dados: 5
Autores: Malod, J.; Mascle, Jean.
The main structural features of the continental margin off West Spitzberg are outlined. Seaward the Atka ridge has acted like a dam for the eastward-flowing sediments and thus helped to build up a large sedimentary basin, narrowing towards the North. Magnetic and seismic data show that the Atka Valley is probably an active accretion rift valley. These results are in good agreement with the last hypothesis on the opening of the Norwegian Sea. During the Pliocene, a tectonic event may have affected Atka ridge and modified the subsequent sedimentation. [NOT CONTROLLED OCR]

La marge nord-africaine considérée comme marge active
Provedor de dados: 5
Autores: Auzende, Jean-marie; Bonnin, Jean; Olivet, Jean-louis.
Based on the study of some seismic-reflection profiles, we demonstrate that the identified sedimentary units show a structural anomaly at the bottom of the North-African continental margin compared to the situation observed on the other margins of the western Mediterranean basin: all the deep Messinian and infra-Messinian deposits are subjected to a flexure when reaching the North-African margin; the created depression is filled by the plio-quaternary deposits. This observation, set back in the geodynamic context of the western Mediterranean, leads to the following interpretation: the North-African margin is a very active margin at a very early evolutional stage. The abnormal structure of the gravity field in the considered region confirms this...

Autores: Duguy, R.
About 20 spp of marine mammals are actually known for the fauna of the north- west African coast (Rio de Oro, Mauritanie, Senegal). This large number of spp seems to be related to cold water areas connected with the 'upwelling' effect. New data, recently collected, mainly during the summer cruise (1973) of the 'Thalassa', supply new information about the distribution of some spp. Souza teuszil shows a northern limit of its range at {approx} 20 {degree}N (Banc d'Arguin) and Stenella longirostris at {approx} 16{degree}15 N. The common porpoise (Phocoena phocoena) seems to be more frequent in Mauritanian waters than in Morrocan ones, and Orcinus orca is commonly observed between Cap Blanc and Cap Timiris.

Signification biologique des teneurs protéiques et des activités de l'amylase et des protéases chez Artemia salina L. aspects d'application a l'étude de la nutrition
Provedor de dados: 5
Autores: Samain, Jean-francois; Boucher, Jean; Buestel, Dominique; Borne, M.; Le Coz, Jean-rene.
The relations between the activity of the digestive enzymes amylase and proteases were studied on Artemia salina L. For this purpose, a method for measuring the ingestion was developed compatible with the speed of response of the digestive enzymes. It is demonstrated that the proteic density variations in Artemia of the same size are in relation to the food content of their digestive tract. Therefore the measurement of the size and weight of proteins (proteic density) allows the evaluation of the ingestion. With the aid of this method, a daily ingestion rhythm, with bimodal character, could be demonstrated. The influence on the ingestion, of the concentration of food available (Tetraselmis suecica Butcher) was studied in function of the size of the...

Recherches sur l'alimentation des crevettes bathypelagiques du talus continental du Golfe de Gascogne.

In the present study, the feeding habits of the bathypelagic shrimps Sergestes arcticus, S. robustus, Pasiphaea sivado, P. tarda, P. multidentata and Psathyrocaris infirma), occurring on the continental slope of the Bay of Biscay, were examined. It was concluded through the present observations that these shrimps use the pelagic resources from the environment. On the other hand, their spatial distribution in different layers prevents any trophic competition between them. The nature of the prey organisms is widely determined by the size, the efficiency of the catching techniques, but also by the possibility of special detection (the hypothesis of ocular detection of euphausiids by P. sivado). The absorption of sediment, during the rest hours, is supposed to...

The study of the feeding behavior of D.cuneata (Moreau)(Soleidae, Pleuronectiformes), and the structure of the alimentary tract, show that this sp is a predator of benthic invertebrates or invertebrate fragments wrecked. According to the increasing depth and the progressive decrease of water movements, its food preference is fragments of adult Bivalvia, Polychaeta and Amphipoda. In this work, the feeding behavior is studied in relation to age, sex and state of sexual maturity. 3 patterns of seasonal bathymetric movements are proposed. (1) Anadromous trophic migration which takes place during sprig with movements towards the coast due to the warming of the waters. (2) Catadromous genetic migration, concerning in summer adults only. (3) In winter, the whole...

Autores: Melguen, Marthe; Thiede, Jörn.
Off the Brazilian coast, the Rio Grande Rise, whose minimum depth is 600 m, acts as a barrier for deep circulation. It is crossed by a long (600 km), deep (4 600 m) and narrow (20 km wide in its central part) channel: the Vema Channel, a junction channel joining the Argentinian and Brazilian basins. Two important currents flow into the Vema Channel. The deepest, the deep Antarctic current, flows from the South to the North at a speed reaching 40 cm/s near the bottom (Le Pichon et al., 1971). Its upper limit is located at around 3 500 and 4 200 m (Le Pichon et al., 1971). Directly underneath, but flowing from the North to the South, is the deep North Atlantic current. Its estimated speed at 2 800 m deep is 15 cm/s. Its upper limit is located at around 1 000...

Parmi les vertébrés marins faisant l'objet d'une exploitation, la tortue verte, Chelonia mydas (fig. 1 ), présente des caractères biologiques remarquables qui laissent présager des possibilités d'élevage productif. Les dépenses énergétiques de la tortue verte sont réduites au minimum : étant aquatique et poïkilotherme, l'animal ne doit assurer ni la sustentation, ni la régulation thermique de son organisme. Les eaux chaudes qui constituent le biotope de cette espèce favorisent l'assimilation. En dehors des migrations pour la reproduction, le comportement peu mobile de C. mydas limite les dépenses motrices.

Deep bottom currents, sedimentary hiatuses and polymetallic nodules

Autores: Pautot, Guy; Melguen, M.
Recent studies undertaken by the Centre National pour l'Exploitation des Oceans have focused some attention on the environment of nickel- and copper-bearing iron-manganese nodules in the Tuamotu Archipelago region of the South Pacific. The results indicate that the distribution of the nodules is closely linked to that of deep currents in the area. We attempt to show that these currents are associated mainly with the Antarctic Bottom Water and we attribute the episodical character of nodule formation in this region to major pulsations of the Antarctic Bottom Water. A synthesis of what are considered to be primary factors in the nodules formation are incorporated into a tentative model which is presented as a guide for future exploration for polymetallic...

The quantitiative requirements for protein have been determined in P. serratus reared from the post-larval stage to the 4th month. It appears that the apparent optimum percentage of protein in the diet is a minimum of 60%. At the 8th month, the mean wt of prawn reared with the best artificial diet (diet IV) is only 49% of the wt of shrimp reared with the digestive gland of Patella as a diet. The prawns reared to 4th month on a low-protein diet then reared on a natural diet until the 8th month, show important compensatory growth. However, the prawns do not achieve the wt of the control population, their average wt representing only 16% of the controls.

Ascophrys rodor (Campillo and Deroux) parasite of the reared common prawn P. serratus).
Provedor de dados: 5
Autores: Deroux, G.; Campillo, Albert; Bradbury, Ph. C.
A disease whose severity seems directly bound to conditions of cultivation can cause a heavy mortality in the common prawn Palaemon serratus (Pennant) at molting. The causative agent, A. rodor, is a ciliate, a common external parasite whose life cycle is adapted to the molting cycle of the shrimp. The principal factors favorable to the development of the parasite were studied: age of the host, water temp, numbers of shrimps as a function of the quantity of water and its renewal. The sp A. rodor, although related to the Conidophryidae, Kirby, 1941 (1936) has significant differences (1) in its ethology (it feeds on the exoskeleton without penetrating to its hosts' tissues), (2) in its vegetative multiplication (tomitogenesis combines the cortical...

Les muges (poissons, téléosteens) de Tunisie-Répartition et pêche-Contribution à leur étude systématique et biologique.
Provedor de dados: 5
Autores: Farrugio, Henri.
Les muges ou mulets sont des poissons Téléostéens très répandus en Tunisie. On les capture sur tout le littoral, depuis le nord jusqu'a l'extrême sud du pays et ils entrent pour une part considérable dans le marché local du poisson. En outre les muges constituent l'une des plus importantes ressources des lacs tunisiens dont l'exploitation, en particulier au moyen de pêcheries fixes, permet d'abondantes captures. Ces poissons sont recherchés par les consommateurs a plus d'un titre. Leur chair est appréciée et plus encore les gonades des femelles a maturité sexuelle. Recueillies au moment de la ponte, ces gonades salées et séchées se vendent sous le nom de "boutargue", produit dont la préparation et la vente donnent lieu en Tunisie a une activité non...

Données histologiques sur l'appareil digestif et la digestion des atlantidae (prosobranchia : heteropoda)
Provedor de dados: 5
Autores: Martoja, Micheline; Thiriot-quievreux, Catherine.
The histological structure o f the digestive system and its histophysiological changes during digestion are described in the adults of 6 species of Atlantidae. The results are interpreted functionally and discussed from the point of view of systematics. The digestive tract of the Atlantidae comprises an oesophagus functioning as a crop, a small stomach and a short intestine. A pair of tubular salivary glands and a digestive gland (hepatopancreas) are associated, but oesophageal and rectal glands are lacking. The radular apparatus has the usual prosobranch characters. The digestive tract is totally devoid of mucous cells. Several unicellular glands are in the buccal wall and the anterior part of the oesophagus. There is an apocrine secretion in the crop....

The FAMOUS (French-American Mid-Ocean Undersea Study) program was designed to conduct an integrated and detailed geological, geophysical. and geochemical study of a portion of plate boundary where new oceanic crust is generated and where some processes leading to the formation of the oceanic lithosphere may appear more clearly (1). The originality of the program was to include the use, for the first time, of precisely navigated, manned research submersibles in the latter phases of the work at sea and thus enable methods of classical field geology to be applied to the study of the deep ocean floor. Collection of data on a scale ranging from centimeters to kilometers was demanded by the narrowness of the surface expression of the plate boundary. [NOT...

La pêche artisanale et en particulier l’ensemble des activités relevant de la pêche côtière et de la petite pêche (les marées durent respectivement moins de 96 et de 12 heures) sont mal connues. Comme elles sont plus difficiles à appréhender que là pêche au large, on a eu tendance pendant longtemps à les négliger. Aujourd’hui, les problèmes concernant les zones côtières se multiplient - construction éventuelle de centrales nucléaires, - développement de l’extraction des agrégats marins par suite de l'augmentation des besoins et de l'épuisement des gisements terrestres, - multiples problèmes de pollution. Tout cela a conduit les Pouvoirs publics à s'intéresser de plus près aux activités de la pêche dans la zone côtière. Dans les Pertuis Charentais, la pêche...

Etude de la nutrition du zooplancton en zone d'upwelling par la mesure des activités enzymatiques digestives
Provedor de dados: 5
Autores: Boucher, Jean; Samain, Jean-francois.
The feeding of the zooplankton has been studied in the natural environment of an upwelling ecosystem by measurements of amylase and protease activities. The hypothesis of enzymatic specific activity as a nutritional index is extended by a correlation with Lorenzen's grazing index. There is no correlation between amylase and protease activity so the diet of the populations is described by the ratio of these two enzymatic activities. Variations of relative feeding rate for Calanus, Temora, Acartia, Podon, and for the total sample are discussed in relation to the ecological and trophic characteristics of the environment.

Autores: Campillo, Albert; Regnault, M.; Luquet, P.
The evolution of nucleic acids in larvae of P. serratus reared in the laboratory from hatching to metamorphosis has been studied. From the 1st larval stage to the post-larval stage, DNA and RNA concn decrease: from 185 to 95 uMoles-bases/g PSD for DNA and from 133.5 to 78.75 uMoles-bases for RNA. The concn decrease is not regular; it is emphasized between stages 4 and 5 on the one hand, and between stage 7 and the post-larva on the other hand. The amount of DNA and RNA per larva increases proportionally to the wet weight from stage 1 to the post-larva. As the weight is multiplied by 7.6, total DNA and total RNA are multiplied by 3.80 and 4.25 respectively. The RNA/DNA ratio has a mean value of 0.77; it increases slightly from stage 1 (0.72) to the...

Plate tectonic and palaeomagnetic implications for the age of the Deccan Traps and the magnetic anomaly time scale
Provedor de dados: 5
Autores: Molnar, Peter; Francheteau, Jean.
IF reconstructions of plate tectonic movement based on magnetic anomaly data are found to be inconsistent with reconstructions based on palaeomagnetic data (see refs 1-3) it may indicate that one or more of the basic assumptions of the plate tectonic model is erroneous :  the age or identification of a particular anomaly may be incorrect, the pole positions or sample ages may be unreliable or there may be an error in assessing plate rigidity. We present an example of inconsistency between the two types of data and explore its implications for the chronology of magnetic reversals during the late Cretaceous and early Tertiary and for the age of the Deccan Traps.

This study deals with D.cuneata, a small soleid listed among the spp of NEAFC Recommendation 2 and exploited by the 'artisanal' trawlers in the South of the Bay of Biscay. The gonads/gutted fish wt ratio has been calculated throughout a yr, and shows that young Dicologoglossa are able to reproduce at age-group II. Spawning takes place during the 3rd quarter. Growth has been determined by otolith reading and length frequency analysis; Bertalanffy's and Gompertz's equations parameters have been studied, and attempts to estimate the instantaneous rate of total mortality have been made. The results are: male Z 3-5=0.74 and 0.83, female Z 3-5=0.96 and 1.35. Selectivity experiments carried out on board of R/V 'La Palagia' give a selection factor of 3.9. The...

Autores: Charlon, Nicole.
The problem of the clogging up of sea water pipes by Mytilus edulis larvae is a very real problem. A study has been made of the ways to destroy these larvae, (1) by electricity (publication in preparation), (2) by ultrasound. This last technique has given interesting data, but exploitation of results on a large scale presents many difficulties. An interesting general phenomenon is to be underlined. For ultrasound treatments of short duration (10s), many larvae are simply stressed and recover later on. For longer treatments, there is actual dislocation of the larvae and instant mortality, this mortality increases with time.

Autores: Gras, Marie-paule.
The mortality that decimated Portuguese oysters, C. angulata, in 1970-1971, up to 80% in most sectors, required the introduction of C. gigas oysters resistant to disease and whose reproduction proved itself to be excellent (GRAS and assoc. 1971). Artificial beds of Pacific oysters were created. Nonetheless, in some areas, there continued to be small populations of C. angulata that, mixed in with the C. gigas oysters that had been brought in, participated in reproduction. Genetic problems then arose, among which the selection of specimens and hybridisation were to be considered more specifically. There are, in fact, two cases of hybridisation.

Provedor de dados: 5
Autores: Aquacop, Aquacop.
In order to determine the feasibility of fish culture in French Polynesia's lagoons, preliminary tests were performed in 1973 and 1974. Juveniles (7 to 10 g) of three Carangidae species (Caranx melampygus, C. elacate, C. ignobilis) were caught in the wild and transported to the laboratory; three lots were dispatched among two small tanks (500 liters) with 10 animals each and a floating cage  (6 x 6 x 4 m; 1.5 cm mesh) with 900 animals. The range of water temperature was 25 ta 27 C, salinity was about 34.5 ppt, and pH was 8.2. Food was given in the form of a moist pellet consisting of 8O% dry powder mixed with fresh bonito flesh or troca flesh. Such a diet has a 40% protein content due essentially to fish meal (sun-dried lagoon fish). These moist pellets...

Utilisation du filet à plancton du type Bongo en milieu côtier
Provedor de dados: 5
Autores: Heral, Maurice.
Le filet Bongo est un filet à plancton américain dont l'utilisation se généralise pour les études de l'lchtyoplancton. Ses dimensions, son pouvoir de filtration et son rendement en  fait un engin performant pour la recherche des larves de poissons. Il est recommandé par l'I.G.N.A.F. groupe pré-recrutement du hareng et il le sera prochainement dans F.A.O. standard Techniques for Pelagic Fish Egg and Larva Sarveys. L' ISTPM utilise ce filet, depuis 1971 , dans de nombreuses campagnes à bord de la Thallassa, du Cryos, de la Pelagia , du Roselys et de Ichtys. En 1975, nous avons décidé d'utiliser ce filet dans des études côtières que l'ISTPM mène en Manohe et en Mer du Nord. Ces travaux ont pour but d'établir un inventaire halieutique qualitatif et quantitatif...

Rigid plate accretion in an inter-arc basin : mariana trough
Provedor de dados: 5
Autores: Le Pichon, Xavier; Francheteau, Jean; Sharman Iii, George F.
It is verified that an oblique rigid opening results in good fit of the rifted portions of arc on each side of the Mariana trough. The good fit suggests that there has been rigid plate accretion and that a plate 200km wide and 1500 km long can stay undeformed between active consuming and accreting plate boundaries.

Détermination des stades d'intermue chez Macrabrachium rosenbergii (caridae) et Penaeus merguiensis (peneidae)
Provedor de dados: 5
Autores: Bourgeois, B.; Cuzon, Gerard; Aquacop.
Ce travail représente une contribution à l'étude de la biologie et de la croissance de la crevette d'eau douce Macrobrachium rosenbergi i (de Man) et de la crevette de mer Penaeus mergaiensis (de Han). Les étapes successives de la période d'intermue ont été déterminées sur des juvéniles afin de pouvoir par la suite approfondir les connaissances de quelques paramètres physiologiques relatifs à la croissance de ces deux espèces. Les notions fondamentales sur le cycle d'intermue des crustacés apportées par Drach (1939) pour les Brachyoures adultes, sont valables avec de légères modifications pour tous les Décapodes qui présentent un exosquelette bien calcifié.

" Tubotomaculum " et nodules de manganèse - Comparaison d'objets énigmatiques fossiles avec des concrétions marines et lacustres
Provedor de dados: 5
Autores: Pautot, Guy; Truillet, René; Hoffert, Michel.
Tubotomaculum are cylinder-shaped bodies a few centimetres long which can be found in pretty large quantities in the "numidian clays" of the upper Cretacean to Oligocene Mediterranean boundary. We present the observations conducted with electron microscopy. Geochemical and mineralogical analyses have been carried out. The manganese and iron contents are similar to the polymetallic nodules covering the bottom of today's oceans. We continued the comparison with the transition element contents (copper, nickel, cobalt). The Tubotomaculums' core is composed of rhodocrosite and siderite, while their cortex is made of non crystallised iron and manganese. The deposition localization is discussed through the analysis of the surrounding sediments. Different...

Les bassins sédimentaires de la mer d'Alboran
Provedor de dados: 5
Autores: Auzende, Jean-marie; Pastouret, Léo; Olivet, Jean-louis; Rehault, Jean-pierre; Szep, Bela.
The study of seismic profiles (made with Sparker and with air-gun) recorded in the Alboran sea helps us to complete and modify an interpretation which was previously made. Further to complementary data on the structural frame, we showed the existence of a salt layer topped with evaporites, in the basins situated on both sides of the Alboran ridges. With regard to the thick infra-salt layer in the western Alboran basin, it appears that the basement of the basin, as a whole, is at a depth similar to the depth of the North-African basin. This supports the hypothesis of a common origin and evolution for both basins. [NOT CONTROLLED OCR]

Donnees pratiques sur l'elevage au laboratoire des larves de Palaemon serratus (Pennant)
Provedor de dados: 5
Autores: Campillo, Albert.
The main factors conditioning the larval development of P. serratus have been studied in the Marine Station at Roscoff. Several types of natural diets have been tested. The nauplii of Artemia salina remain the most practical food. However, it was necessary to verify that a diet of Artemia permits development to a normal mysis. In these experiments, only Artemia originating in California, gave satisfactory results (84.5% viable post-larval shrimps). The most favorable density of larvae during cultivation was between 50 and 100/1. The larvae of P. serratus resisted very wide and sudden variations in salinity. However, when the salinity was &lt;12 ppt, there was 100% mortality. The maximal survival of post-larval shrimp was at 25 ppt. The temp had an...

Etude des fonds de pêche du littoral atlantique martiniquais : ressources, exploitation, prospectives
Provedor de dados: 5
Autores: Farrugio, Henri; Saint-felix, Christian.
The Atlantic coast of Martinique shows the typical characteristics of the tropical regions with a coral facies, and especially: a) a wide variety of sedentary animal species, especially coral fishes, of smaller sizes and numbers, thus forming smaller populations than those living under other latitudes ; b) the presence, between the shore and the reef barrier, of a shallow strip of soft bottoms, without any natural shelter, well protected, but with difficult access for off-shore species, and with a poor fauna. It is the major explanation for the weakness of the performances on this restricted continental shelf where, in addition, the fishing effort keeps growing. The complex relief of the reef makes the use of the trawl nets impossible and very difficult...

Techniques d'élevage en masse d'un Rotifère (Brachionus plicatilis Müller) et d'un Crustacé Branchiopode (Artemia salina L.)
Provedor de dados: 5
Autores: Person-le Ruyet, J.
This work deals with the influence of the diet (qualitative and quantitative aspect) on the daily production of a population of Brachionus plicatilis and on the growth an survival of the brine shrimp Artemia salina. It was tried to reduce the manipulation to a minimum and to use the available volume most adequately. For B. plicatilis the best results were obtained with fresh Tetraselmis suecica as food. Nevertheless it is possible to maintain the population at a satisfactory level of production with preserved food. For A. salina the use of algae powder gave the best growth and survival. It is demonstrated that it is worth using low cost, easy to store dried food, which permits mechanical feeding. [NOT CONTROLLED OCR]

Application to the albacore (Thunnus alalunga.) monthly catch per unit of effort (C. P. U. E.) by the Atlantic Japanese longline fishery
Provedor de dados: 5
Autores: Laurec, Alain; Le Gall, Jean-yves.
Two different statistical techniques of analysis have been worked out in order to analyse the components of available data of catch per unit of effort (C. P. U. E. by month), used as an abundance index, for the Atlantic Japanese tuna longline fishery harvesting north-southern stocks of albacore (Thunnus alalunga). These techniques have been developed in order to estimate different components of this abundance index, such as yearly trend, a seasonal component, fishing effort impact, and unknown residual component. Both techniques combine these components either in an additive model or multiplicative one and allow to assign to the trend a continuous or discrete (stepwise) shape. The first technique is simple, it is called " moving average " and applies...

The Seismic Structure of the Western approaches and the South Armorican Continental Shelf and its Geological Interpretation
Provedor de dados: 5
Autores: Avedik, F.
Based on all available seismic refraction data, the seismic structure of the Western Approaches to the English Channel and the South Armorican continental shelf has been established. The correlation of seismic velocities showed a three-fold structure, related to geological layers as follows: 1. High-velocity, deep sequence (4.4-6.6km/sec): metamorphic basement and Lower to Middle Palaeozoic. 2. Intermediate sequence (3.6-4.3km/sec): Permo-Triassic (and Jurassic?) and possibly also Lower Cretaceous on the margin of the Western Approaches. 3. Upper sequence (1.9-3.6km/sec): Cretaceous and Cenozoic sediments. An acoustic unconformity appears to be present between the Upper sequence and the High velocity and Intermediate sequences.

Two new species are described : Dytaster cherbonnieri and Benthopecten chardyi. The analysis of infraspecific variations of Freyella spinosa makes doubtfull the validity of F. spinosa var. abyssicola. Most species are widely distributed in the whole atlantic Ocean ; they were previously known merely from the Northern Atlantic. The Walvis ridge does not appear as a boundary for the dispersion of the Asterids. [NOT CONTROLLED OCR]

In fact, coastal swell near to the breaker zone is feared by engineers when evaluating the stresses exerted on coastal civil engineering structures. This fear is mainly caused by the phenomenon's complex nature; a nature which can only be partially represented by the current theoretical models. Experimentally speaking, the observation techniques we have enable the quantitative study of coastal swell near to the breaker zone, as well as the characterization of some of its properties and the testing of some theoretical models which are valid off shore and could be adapted to the coast. This study demonstrates the strong non-linearity of free surface movements. It also details the conditions of utilization of the Airy and long wave theories in the evaluation...

Autores: Raimbault, René; Arnaud, P; Hamon, Pierre-yves.
In 1973 the" Institut des Peches Maritimes (Centre de Sete) "prospected the Mediterranean coasts to obtain information about the possibilities of collecting flat oyster (Ostrea edulis) spat.  Plastic collectors were submerged at 20 stations in the Golfe du Lion. In spite of some lose of equipment, observations have allowed to see that spat densities were excellent (5.5 to 9.4 per dm2 of collector) in most areas.

Les problèmes de l'environnement liés à l'exploitations des sables et graviers marins - Note technique n°51
Provedor de dados: 5
Autores: Debyser, J.
Le CNEXO a entrepris depuis 1968, sous l'égide du Groupe des Agrégats Marins de la Commission de Carrière du Conseil Général des Mines et avec la collaboration technique et financière du BRGM et d'industriels, l'inventaire des réserves de sables et graviers disponibles sur le plateau continental français. Des réserves significatives ont été mises en évidence, tant en Manche que dans le Golfe de Gascogne. On estime généralement que l'exploitation de ces matériaux pourra, dans une certaine mesure, prendre le relais des ballastières terrestres qui s'épuisent et dont l'exploitation pose de sérieux problèmes à l'équilibre hydrogéologique et, plus généralement à l'environnement terrestre. Encore faut-il, avant de consentir à l'utilisation de ces nouvelles...

Geophysical study of the easternmost Walvis Ridge, South Atlantic: Deep structure
Provedor de dados: 5
Autores: Goslin, J.; Sibuet, Jean-claude.
A seismic-refraction study of the sedimentary structure of the South West African continental shelf was carried out between lat 17°S and 24°S using expendable sonobuoys. Striking differences exist both in the topography and sedimentary structure between the shelf north and south of the Walvis Ridge. South of the ridge, as far as lat 23°S, the shelf consists of a prograded series, whereas north of the ridge, at least as far as lat 17°S, east-trending canyons cut the shelf sedimentary cover. The steep northem scarp of Walvis Ridge can be traced eastward under the sediment of the continental margin. The southern flank of the ridge is buried under a thicker sedimentary cover and could only be traced eastward to long. 10°E on seismic-reflection records. This...

Structure de la marge continentale norvégienne au débouché de la mer de Barentz
Provedor de dados: 5
Autores: Briseid, E.; Mascle, Jean.
Reconstructions of the continents prior to the opening of the Norwegian sea indicate an overlap between the Greenland and the Norwegian continental margins just west of the Barentz sea and imply that the basement of this area is of oceanic origin. Seismic profiling shows an oceanic-type basement covered by thick Tertiary sediments. The sedimentary supply is related to the geological history of the Barentz sea where only little unconsolidated sediments are known. Further south the structures of the present margin are directly related to the early opening of the Norwegian sea. [NOT CONTROLLED OCR]

Submersible study of lower continental slope-abyssal plain contact
Provedor de dados: 5
Autores: Le Pichon, Xavier; Hekinian, Roger; Francheteau, Jean; Carre, Daniel.
IN OCTOBER 1972, the bathyscaphe Archimède made a series of training dives-to a 2600-m water-depth off northwest Corsica in order to test new equipment.Two of these dives (72-5 and 72-7) were made at the limit of the lower continental slope and the abyssal plain near an acoustic transponder (X'4 in Fig. 1) with respect to which the submersible could position itself with an accuracy of 10 to 200 m within a radius of 1450 m. The position of X'4 with respect to the geographic grid is not known to better than 200 to 300 m. We feel, however, that the position of the transponder shown on Fig. 1 leads to a good agreement with the relief revealed by the bathymetric map. These dives, in spite of technical shortcomings, gave some unexpected information about the...

Continuous spat production of flat oyster - Ostrea edulis in running water
Provedor de dados: 5
Autores: Flassch, Jean-pierre; L'Herroux, Michel; Laubier, Lucien; Aveline, C.
The breeding of bivalve larvae has up t o now always been conducted in closed systems. This method requires great care and consequently much labor. Using running water systems, we intended to exclude handling and avoid infestations and diseases without the use of antibiotics . Primarily, we used two cylindrical 20 m3 tanks, both with a filtering sand bottom and air-lift system. The flow was about 400 liters/hr. The temperature was 20 C. One tank was used as the filter, the second as our breeding unit in which circulation was maintained by adapted aeration. Newly released larvae of Ostrea edulis were introduced at four times. Larvae were fed daily at a rate of from 10 Isochrysis galbana, 10 Monochrysis lutheri and 2 Tetraselmis suecica per microliter to 25...

Autores: Campillo, Albert.
The growth of post-larval P. serratus has been studied until the appearance of secondary sexual characters, in order to eliminate the influence of sex ratio on the mean wt. The influence of temp on intermolt period and number of molts was observed in male and female kept individually. Different sorts of food of natural origin have been tested. The rearing of post-larval lots metamorphosed at different times of the yr showed that the growth of P. serratus is conditioned not only by the temp, but also by the season. The food conversion ratio was defined in relation to the sex and age of the prawns. Shelters allowed the author to obtain a ratio of survival which varied post-larvae per square meter. The sex ratio established from several breedings as soon as...

Provedor de dados: 5
Le projet de construction d'une centrale nucléaire à Port-la-Nouvelle doit constituer la première tentative d'implantation d'une unité de production d'énergie électrique de 4 500 megawatts sur les côtes françaises de Méditerranée. L'installation de cette centrale sur le littoral est essentiellement déterminée par la nécessité d'évacuer sous forme calorifique la puissance thermique résiduelle due à son fonctionnement. L'évacuation de cette puissance résiduelle sera assurée par une circulation permanente d'eau de mer qui sera restituée au milieu marin après avoir subi une élévation de température non négligeable lors de son passage dans les condenseurs.

Provedor de dados: 5
Autores: Girin, Michel.
During the spring of 1974, 364,000 sea bass larvae, obtained from natural spawnings in captivity, were reared up to 1 month , in 60-500 l tanks in 22 different experiments. The only food for the fish larvae, consisted of the rotifer Brachionus plicatilis Müller, and nauplii or metanauplii of the branchipod Arternia salina L. Larval density at the beginning of the experiments ranged from 28-154/l. It was reduced after 1 month to 2-32 larvae/l., the survival ranged from 3-69 %. Under the experimental conditions employed, survival seemed to be stricktly related to the daily feeding regime. Both survival and growth seemed to be independent from the size of the culture tanks and from the larval density. The nutritional budget of 30 day old fingerlings was...

Row Cropping Sandy Soils Under Sprinklers Using a Winter Grain Cover to Control Wind Erosion
Provedor de dados: 18
Autores: Cary, J.W.; Kohl, R.A.; Westermann, D.T.; Rickman, R.W.
One of the most effective ways to prevent the wind erosion  of sandy soils is to maintain a continuous crop cover. Summer  row cropping following a winter grain cover offers several  attractive features, although it does present management  problems. The grain cover must be established in the fall  after harvesting the row crop, and the transition back to a  row crop in the spring must be made without leaving the  soil surface unprotected from the wind.  This report summarizes 4 years of observations and  exploratory studies in which a variety of cover-row cropping  management systems were tested with emphasis on methods  for establishing row crops directly in the winter cover.  Pertinent literature and observations of other field trials  are also discussed.

Use of Amendments to Reduce Water Requirements for Stand Establishment of Small-Seeded Crops
Provedor de dados: 18
Autores: Dennis, R.E.; Edmond, C.W.; Robbins, C.W.
Soil crusting after planting is a serious problem in stand establishment  of small-seeded crops in the Southwest. When crusting occurs in a  saline, warm soil, stand establishment problems are especially severe. It  is customary to use costly irrigation water to keep seedbed surfaces moist  after planting to reduce soil crusting and to lower soil temperatures.  Phosphoric acid (24% and 12%) and sulfuric acid (95%) were evaluated  to determine their effectiveness in reducing soil crusting and reducing  the amount of water required to obtain stands of sugarbeets, alfalfa,  wheat and barley.  Phosphoric acid, applied in 4-6 cm bands over the seed row at  planting and before irrigation, reduced crusting and increased sugarbeet  and alfalfa seedling emergence....

A list of the birds known from Roti and adjacent islets (Lesser Sunda Islands)
Provedor de dados: 16
Autores: Mees, G.F.
INTRODUCTION Father Verheijen (in press) has given a narrative of his visit to Roti, with a list of all birds recorded from material, personal observations, and hearsay. Although several of Verheijen's own field observations are entirely reliable, other species mentioned by him cannot be regarded as of anything but very doubtful occurrence. Therefore I have considered it useful to compile a list of those birds which are now known from collected specimens. Previous to Father Verheijen's studies, ornithological knowledge of Roti rested entirely on a visit to the island made by the anthropologist Dr. H. F. C. ten Kate in 1891 (22 August — 9 September). During his stay ten Kate did some collecting of miscellaneous zoological objects, which he forwarded to...

Vegetative anatomy and the affinities of Aquifoliaceae, Sphenostemon, Phelline, and Oncotheca
Provedor de dados: 16
Autores: Baas, P.
The anatomy of leaf, node, twig, and bark of Ilex, Nemopanthus, Oncotheca, Phelline, and Sphenostemon is described, together with the wood anatomy of the 4 latter genera. Several characters are recorded for the first time. The systematic value of some anatomical characters for judging the wider affinities of the genera involved is discussed. Considering these characters together with macromorphological and palynological data, it is concluded that Phelline and Sphenostemon each merit family status, and have affinities with Aquifoliaceae and Icacinaceae of the Celastrales. Oncotheca shows no affinities with the families of Celastrales, and may possibly have its closest relatives in Theales, but this problem has not been studied in great detail. The leaf...

Autores: Hooijer, D.A.
In 1876 beschreef Van Beneden (1876: 799) resten van een kleine zeehond uit het Scaldisien van het Bekken van Antwerpen als Phocanella minor. Newton (1891: 19/20) meldde een humerus fragment van deze soort afkomstig uit het Nodule Bed van de Red Crag bij Foxhall, 4 mijl Z.W. van Woodbridge in Suffolk. Een fragment van een femur werd door Van Deinse (1927: 1363) gerapporteerd van de Groeve van Wiegerink ten noorden van Zwolle; dit zou tot nu toe de enige fossiele vondst van Phocanella minor uit ons land zijn. Het zwarte botje waarvan hier nu melding wordt gemaakt ontving ik van Dr. P. H. de Buisonjé en is afkomstig van een schelpenzuiger in de Westerschelde.

Hesionura augeneri Goniadella Bobretzkii, and Parapodrilus psammophilus (Annelida, Polychaeta) : new to the Netherlands
Provedor de dados: 16
Autores: Wolff, W.J.; Stegenga, H.
INTRODUCTION AND METHODS During an investigation of distribution and ecology of the Archiannelida of the estuarine area of the rivers Rhine, Meuse and Scheldt in the southwestern part of The Netherlands, three species of polychaetes new to the Dutch fauna were found. Because these species have not been reported very frequently from other localities, the finds are described in some detail. The first two species were found in samples taken with a o.i m2 Van Veengrab; the last one originated from a core sample taken in the beach. After collecting the samples have been treated in the way described by Boaden (1963).  RESULTS AND DISCUSSION Hesionura augeneri (Friedrich, 1937) (fig. 2) This species was found at two localities in the coastal water (fig. 1) at...

In the course of studying the Asteraceae for a proposed Alpine Flora of New Guinea the first author selected the genus Cotula for this separate paper as it showed some variability that was not easily explained. While working on this, Dr. Lloyd’s paper on the genus in the New Zealand Journal of Botany 10 (1972) 277, came to his notice and on corresponding with him it turned out that he had studied the New Guinea species already to some extent but had nothing ready for publication. At the same time, Dr. J. Koster of Leiden, Netherlands, was known to work on a study of all Asteraceae of New Guinea and it soon transpired that when the manuscript was finished and a copy sent to her that very same day she had put down the first words of her manuscript on this...

Provedor de dados: 16
Autores: Spoel, S. van der.
A new method for the use of infraspecific variation in the characterization of watermasses in the past is indicated. The various formae of the thecosomatous pteropod Clio pyramidata can be distinguished by the size of their protoconch. Since in marine sediments these protoconchae are usually the most intact part of the pteropod shells, they can be used to trace the distribution of the formae in the past, and thus of the watermasses of which these are characteristic.

A botanical evaluation of some nature reserves in the province of Overijssel The method of botanical evaluation by MENNEMA (1973), based on the flora statistics of VAN DER MAAREL (1971) depends upon inventarisation of 1 kilometer squares. In the present study the floristic lists of seven nature reserves in the province of Overijssel were used and the results compared with those of Mennema. Furthermore this new objective method was used to attempt to compare the relative botanical importance of the reserves. The results fairly well agreed with those of Mennema using results from reserves of c. 40 ha, but this was not the case with the smallest reserve ,De Maat’ of 8 ha. The author considers that the selected reserves have natural boundaries and the values...

Autores: Florschütz, Peter A.; Grolle, Riclef.
Conservation of Herberta Gray mut. Lindb. 1875 was rejected by the ‘General Committee’ because of the existence of Herbertia Sweet 1827, a legitimate name in common usage for an Iridaceae genus. Therefore the illegitimate Herberta Gray mut. Lindb. 1875 must be abandoned. The simplest solution seems to be the return to Herbertus Gray 1821, the original legitimate name fully in accordance with the ICBN. This is possible without any further action and avoids any new combination.

1. Pyrgus alveus caucasius Picard and Pyrgus jupei Alberti In a paper on Pyrgus bellieri, Picard (1949: 57) casually named the populations of Pyrgus alveus from the Caucasus and Transcaucasia caucasius. According to Picard, Reverdin (1915) confused this form with the Chinese sifanicus which has different genitalia. The description of caucasius is very short: "Il faut mentionner l'extrême petitesse de la pièce constituée par l'antistyle et le stylifer, ainsi que l'aspect externe qui n'est pas sans ressembler au P. bellieri typique des Alpes". Further, Picard referred to the figures of Reverdin (1915, pl. 5 figs. 5, 6 and 7). Alberti (1967) described the species Pyrgus jupei from the Caucasus, mainly based on the small proportions of the style and antistyle....

Autores: Willems, J.H.; Pruissen, A.M.F.C. van; Sambeek, M.J.P.W. van.
The authors report the discovery of Scheuchzeria palustris L. in the eastern part of the Belgian Kempen in the summer of 1974. This find is of importance a.o. from the viewpoint of plantgeography, since Scheuchzeria had not been found in Belgium after 1946, and therefore was considered extinct there. The species had never been reported earlier from the region where it was found in 1974 (fig. 1). In August 1974 14 plants in fruit were counted in a bog situated on a plateau consisting of fluvial sand and gravel deposits of pleistocene origin, about 90 m above sea level, in the municipality of Maasmechelen. The plants grew in a depression between a Sphagnum island and the gradually rising margin of the fen, together with Sphagnum cuspidatum, Juncus bulbosus,...

Redescriptions of two Porricondyline gall midges originally described by De Meijere (Diptera, Cecidomyiidae)
Provedor de dados: 16
Autores: Yukawa, J.; Nijveldt, W.
The confusion of nomenclature and classification in the European Porricondylinae was largely cleared up by the excellent revisionary work of Panelius (1965). There are, however, still many unidentified species listed in his revision owing to the destruction of types and the inadequacy of many original descriptions. Recently, we have had an opportunity to examine De Meijere’s type specimens kept in the Zoölogisch Museum, University of Amsterdam. Because the specimens were not kept in good condition for examination, we dissected some parts of the specimens and remounted them by using Berlese medium. The following are redescriptions of two porricondyline gall midges described by De Meijere (1901, 1906). In particular, detailed examination of the male...

Naast de vegetatiekundige bijdrage van W. G. Beeftink, Ecologie en Vegetatie met betrekking tot het Deltaplan, waarvoor de speciale aandacht van de lezers van Gorteria wordt gevraagd, zijn diverse andere tijdens dit symposium gehouden voordrachten dermate belangrijk en vaak (gelukkig) niet uitsluitend tot het Deltagebied beperkt — al zijn daar de om een oplossing vragende problemen bijzonder groot — dat dit boekje een grote lezerskring zeker verdient.

Boekaankondigingen
Provedor de dados: 16
Autores: Mennema, J.
Meer en meer komen wij tot de conclusie, dat een tijdschrift als Gorteria zich eigenlijk niet kan veroorloven om boekbesprekingen op te nemen. Te vaak komt het voor, dat een boekbespreking vele maanden lang moet blijven liggen, omdat er net geen plaats of tijd voor was. En dat, ondanks het feit, dat juist vanwege de geringe beschikbare plaatsruimte de boekbesprekingen behoudens enkele uitzonderingen zo kort mogelijk worden gehouden. Dit alles brengt met zich mede, dat het voor diverse uitgevers niet aantrekkelijk is om boeken ter recensie aan Gorteria aan te bieden, omdat de recensie soms te lang op zich laat wachten. Deze veronderstelling wordt gevoed door het feit, dat de meeste boeken, die wij bespreken, ons op ons verzoek zijn toegezonden.

Autores: Girisch, H.B.; Dennert, H.G.
The migratory activity of Gammarus zaddachi and Gammarus chevreuxi is investigated in a current chamber, in which a tidal cycle can be simulated. In fresh running water the number of animals drifting with the current is of about the same magnitude as the number of animals actively swimming against the current. A diurnal periodicity is recorded in the migratory activity. The migratory activity is influenced by the population density and the food supply. In the current chamber a tidal cycle can be simulated by varying the factors current velocity, current direction, salinity, and temperature. The combination of a decrease in current velocity, followed by a slow current in the opposite direction, an increase in the salinity, and a rise in the temperature of...

Taxonomic considerations on Branchiostoma caribaeum from Jamaica
Provedor de dados: 16
Autores: McShine, A. Hazel.
1. The original descriptions of Branchiostoma caribaeum are reviewed and the synonyms for the species mentioned. 2. A statistical analysis was carried out on twelve taxonomic characters of specimens of B. caribaeum from Kingston Harbour, Jamaica. The twelve characters were: total myotomes; preatriopore myotomes; postatriopore myotomes; myotomes between atriopore and anus; postanal myotomes; caudal fin length as a percentage of total body length; body depth as a percentage of total body length; dorsal fin ray chambers; ventral (preanal) fin ray chambers; gonads (on right side only); buccal cirri (on right side only). 3. The characters were ranked in order of increasing variation or decreasing taxonomic significance. The least variable and therefore the most...

A note on the occurrence of Oligochoerus limnophilus Ax &amp; Dörjes (Turbellaria, Acoela) in freshwater habitats in the Netherlands
Provedor de dados: 16
Autores: Dörjes, J.; Young, J.O.
The only hitherto known freshwater acoelan, Oligochoerus limnophilus, has been fully described by Ax &amp; Dörjes (1966). It has been recorded from habitats of different European rivers: Elbe, Ilmenau, Lahn, Main, Mosel and Donau (Kothé, 1961, 1962; Kothé &amp; Sturz, 1963; An der Lan, 1964) where it prefers to settle on artificial stone embankments and is absent from typical lenitic regions and in river parts with a high organic pollution. The species has also been recorded from irrigation canals of rice fields in the Camargue (leg. U. Graefe). Ax &amp; Dörjes (1966) suppose that O. limnophilus emigrated during postglacial periods out of the ponto-caspian area into their new environments because all the other species of the genus have been found in the...

A synopsis of the African and Madagascan Rubiaceae — Naucleeae
Provedor de dados: 16
Autores: Ridsdale, C.E.; Bakhuizen van den Brink Jr, R.C.
The centre of distribution of the Naucleeae is Malesia and Asia, there are but a few African and Madagascan representatives. The revision of the group for Flora Malesiana entailed an extensive nomenclatural evaluation and typification of the genera (Bakhuizen van den Brink Jr., 1970). This has been followed by detailed taxonomic investigations and a re-evaluation of the tribal and generic limits. The Naucleeae, as conceived by K. Schumann (1891), have mostly been considered a highly natural group (Verdcourt, 1958) and have even been raised to family status (Airy Shaw, 1973). Bremekamp (1966) has been the only botanist ever to question the homogeneous nature of the Naucleeae. However, after re-examination of materials of most representatives of all genera...

The morphology and nomenclature of the characteristic, probably monotypic, stilbellaceous hyphomycete genus Tilachlidium Preuss has been dealt with by Petch (1937) and Gams (1971: 141). A perfect state was then unknown. Colonies of the fungus in vitro are rather similar to those of Nectria viridescens Booth. The conidial state has now been found in nature connected with a hypocreaceous (nectriaceous) perfect state.

Provedor de dados: 16
Autores: Blommers-Schlösser, Rose M.A.
In this paper, tadpoles belonging to three related groups of Malagasy frogs are described; both the Dyscophinae and the Cophylinae are subfamilies of the Microhylidae, while the Scaphiophryninae are alternatively assigned to this subfamily or to the Ranidae. The larvae were reared up to the juvenile stage in order to classify them. The tadpole of Dyscophus quinquelineatus (Dyscophinae), the first to be described within the genus, is of the microphagous microhylid type; it has a median spiracle, neither denticles nor beak or papillae, the nostrils do not appear until shortly before the metamorphosis, and the forelimbs develop behind the branchial chambers.

INTRODUCTION A recent study of the lectotype specimen of the Blaauwbok (Husson &amp; Holthuis, 1969) had awakened our interest in this South African Antilope, which became extinct around 1800. One of us got the chance to procure a copy of the 1727 Dutch edition of Peter Kolb's account of Cape of Good Hope, a work containing the first description of the Blaauwbok. The study of this edition of Kolb's work lead to some interesting discoveries concerning the first published figures of the Blaauwbok and the Greater Kudu, which are discussed below. Hippotragus leucophaeus (Pallas, 1766), the Blaauwbok Erna Mohr (1967), in her interesting monographic account of the Blaauwbok, showed that Peter Kolb's account of the Cape of Good Hope was the first published source...

New taxa of Streptaxidae and Enidae (Mollusca, Gastropoda Pulmonata) from South Africa and Malawi
Provedor de dados: 16
Autores: Bruggen, A.C. van.
For various reasons a number of discoveries in the field of Southern African malacology has now reached a point where there is no need for further delay in publication. In the course of a long term project, the revision of the Streptaxidae of Southern Africa, three new taxa have come to light which are described below. Mr. C. C. Appleton (Bilharzia Research Unit, Nelspruit, South Africa) during an extended period of research in Tongaland (NE. Zululand, South Africa) has found a remarkable new form of the genus Gulella L. Pfeiffer, 1856. This is seemingly closely related to a recently described extinct species from Aldabra Island in the western Indian Ocean (Van Bruggen, 1975). It is an unfortunate consequence of the rules of zoological nomenclature that...

The leaf, twig, and nodal anatomy of Alzatea, Axinandra, Crypteronia, Dactylocladus, and Rhynchocalyx is described in detail. This family, as newly delimited by Van Beusekom-Osinga and Van Beusekom, appears to be very heterogeneous, a conclusion supported by the wood anatomical diversity reported in another paper. The nodes may be simply unilacunar, unilacunar with a complete girdling trace, of the common gap (or split lateral) plus median trace type, or trilacunar. Cortical bundles may be present in addition. Further diversity is present in e.g. cuticular texture, stomatal type, hypodermal development, arrangement of vascular bundles in petiole and midrib, mechanical support of the veins, the crystal complement, foliar sclereids, and cork origin....

INLEIDING De Kagerplassen, gelegen bij Warmond ten noorden van Leiden, bestaan uit een aantal met elkaar verbonden plassen, doorvaarten en boezemwateren (fig. 1). Deze plassen zijn een restant van de Haarlemmermeer, welke in 1852 werd drooggelegd. Zij dienen als boezemwateren voor het Rijnland. De wateraanvoer gaat via de inlaat van de Hollandse IJssel bij Gouda door de Rijpweteringse vaart, de Zijp en de Zijl en in mindere mate via de Haarlemmermeerringvaart ten oosten van het gemaal Leeghwater. De afvoer van dit water met een tamelijk laag chloridegehalte, maar met een hoog gehalte aan organisch materiaal, gaat via de uitlaat bij Katwijk en voor een klein deel via het gemaal bij Spaarndam, dus voornamelijk via Spriet en Laeck — Warmonder Leede en soms...

Wood anatomical classification using iterative character weighing

Autores: Hogeweg, P.; Koek-Noorman, J.
In this paper we investigate the pattern of wood anatomical variation in some groups of Rubiaceae (i.e. Cinchoneae, Rondeletieae and Condamineae) by using a numerical pattern detection method which involves character weighing (Hogeweg 1975). In this method character weights are obtained iteratively on the basis of the distribution of character values in previously generated classes; these classes being generated by agglomerative cluster analysis, initially with characters weighed equally and subsequently with characters weighed differentially as indicated above. The result of such a study consists of a sequence of dendrograms together with the character weights by which these are produced. Our biological conclusions include: The so obtained results confirm...

Corallovexiidae, a new family of transformed copepods endoparasitic in reef corals with two new genera and ten new species from Curaçao
Provedor de dados: 16
Autores: Stock, Jan H.
Quite a few endoparasitic copepods are known from Indo-Pacific stony corals, but not a single species has so far been recorded from the West Indies. Intensive search in the past few decades has even supported the prevailing opinion that West Indian stony corals are devoid of endoparasitic copepods, and that this absence could be related to the complicated zoogeographic past of the West Indian reef. However, during a 6-months stay (November 1973—April 1974) at the Caribbean Marine Biological Institute, in Curaçao (Netherlands’ Antilles), endoparasitic copepods have been found in not less than 14 species of stony corals. Some of these belong to a new family of curiously transformed animals, the CORALLOVEXIIDAE, of which the following forms were found during...

On Jamaica many of the endemic land birds are poorly known from an ecological and behavioral standpoint. Therefore, the following information on the food, foraging behavior, and habitats of the Jamaican Lizard Cuckoo Saurothera vetula), obtained while engaged in other studies, should be helpful in the future analyses of this species. To my knowledge the only references to its food habits are that of GOSSE (1847) who found invertebrates (caterpillars, locusts, and spiders) and vertebrates (Anolis lizards and a mouse) in the stomach of this species and of DANFORTH (1928) who found a large green lizard Anolis garmani) and beetles in the stomach of a bird he collected.

A. truncatella truncatella hat pigmentierte Augen, A. dabovici hingegen is blind; die anderen Arten sind nur nach dem Gehäuse bekannt. Die Gattung wird ausschliesslich in Südost-Europa gefunden (Grossu &amp; Negrea, 1968; Pilsbry, 1924). Fossilfunde sind nicht bekannt (Zilch, 1959: 172).

Post-juvenile moult of the Bearded Tit, Panurus biarmicus (Linnaeus, 1758), in Zuidelijk Flevoland, the Netherlands (Aves, Timaliinae)
Provedor de dados: 16
Autores: Buker, Joop B.; Buurma, Luit S.; Osieck, Eduard R.
The post-juvenile moult of the Bearded Tit, Panurus biarmicus, has been described quantitatively on the basis of mass trappings of the explosively increased population in Zuidelijk Flevoland, the Netherlands. The strongly scheduled moult takes place from the end of July till the beginning of October, a period during which practically all wing feathers are being replaced in 56 days. Body feathers are moulted at the same time as the wing feathers but this process is completed later. The post-juvenile moult causes a considerable reduction in flying capacity. Tentativily the timing of this moult is related to other activities of this species in summer and autumn.

On Bourletiella (Cassagnaudiella) pruinosa (Tullberg, 1871) and its allies (Collembola: Sminthuridae)
Provedor de dados: 16
Autores: Ellis, Willem N.
In dry dune vegetations in the Netherlands a species of Bourletiella occurs that is closely related to B. pistillum Gisin, 1946, and B. radula Gisin, 1946. The species is characterized by a virtually obligatory sexual neutralisation of all males throughout the summer. A study of type material proved the identity of this species with Bourletiella pruinosa (Tullberg, 1871). A lectotype is selected for B. pruinosa as well as for B. agreni Stach, 1956. B. agreni, created for B. pruinosa sensu Ågren, 1903, Linnaniemi, 1912, is proved to be a junior synonym of B. pistillum. B. pistillum incisa n. ssp. is described from the Pyrenees and the Ardennes. Bourletiella cruciata Haybach, 1972, is shown to be a sexually neutralized form of B. pistillum, and is a junior...

Tree Architecture, in Field and Herbarium
Provedor de dados: 16
Autores: Ridsdale, C.E.
Tree architecture, the growth form of woody tropical plants, from lofty ’pagoda’ trees to low understorey pachycauls, has captured the imagination of professor and student alike. Previously many attempts had been made to study the growth form of limited plant groups,, but only recently has it been possible to see the wood from the trees as a result of the excellent work by Hallé &amp; Oldeman (1970). This small book is crammed full with a wealth of information and profusely illustrated with clear schematic line drawings, supplemented here and there with photos of the habit of selected plants. The presentation, the clear style, and the excellent drawings offset any problems one might have with the language. The growth form is analysed into a number of...

On the identity of Polyporus schulzeri Fr
Provedor de dados: 16
Autores: Tortič, Milica.
The existing collection of Polyporus schulzeri Fr. (≡ P. irpex Schulzer) in the Natural History Museum at Vienna (W) agrees microscopically with Schulzer’s unpublished observations and is therefore considered to represent the type specimen. A comparison of this material with specimens of Piptoporus soloniensis (Dub. ex Fr.) Pilát showed that both fungi are identical in structure and represent, in fact, the same species. A detailed study of fresh material and a thorough revision of the genus Piptoporus is needed before it can be decided if a new genus should be described for this species. In Piptoporus the correct name is P. soloniensis with P. schulzeri as a synonym.

A taxonomic revision of Buergersiochloa Pilg. (Gramineae)
Provedor de dados: 16
Autores: Fijten, F.
Buergersiochloa was described by Pilger in 1914 with B. bambusoides as the only species. A second species was added by S. T. Blake in 1946. Very little is known about this genus; the plants appear to be very rare in lowland primary forests of New Guinea and only 11 collections are presently known, nine of which were directly available for this study, while of a tenth extensive descriptions and drawings have been published. As was already pointed out by Pilger Buergersiochloa is evidently related to Olyra Linné. Phytogeographically this is very interesting, as Olyra belongs to the Olyreae, a tribe of the Bambusoideae practically restricted to the forests of Central- and South America. Only O. latifolia Linné is found also in Africa and Madagascar (probably...

Peltomyzon rostratum n. gen., n. sp., a siphonostome cyclopoid copepod associated with the West Indian coral Montastraea
Provedor de dados: 16
Autores: Stock, Jan H.
A new species representative of a new genus of Copepoda is described. It belongs to the subfamily Cletopontiinae of the family Asterocheridae (Cyclopoida siphonostoma). The new genus is chiefly characterized by the 2-segmented nature of the endopodites of legs 3 and 4, by the absence of an exopodite in the posterior antenna, and by the strongly developed tergum of the 2nd metasomite, giving the animal a shield-shaped appearance. Only the female sex of this copepod has been found; it is an associate of the hermatypic coral Montastraea cavernosa (L.) on the South coast of Curaçao (Netherlands’ Antilles), in depths from 4 to 40 meters.

Observations on taxonomy and distribution of some Salps (Tunicata, Thaliacea), with descriptions of three new species
Provedor de dados: 16
Autores: Soest, R.W.M. van.
The Salp genera Traustedtia Metcalf, 1918, Weelia Yount, 1954 and Brooksia Metcalf, 1918 are revised, resulting in the conclusion that Traustedtia is a monotypical genus, and that Brooksia on the other hand, contains two taxa, one of which is newly described under the name B. berneri. Weelia shows a confusing variation, which must await further study. The variation in Ihlea punctata (Forskål, 1775) shows that there is no ground for the assumption that the species described as Ihlea asymmetrica (Fowler, 1896) is separate from I. punctata. Two undescribed taxa, reported upon in previous studies of the present author, are now fully described as new species: Cyclosalpa danae and Thalia rhinoceros.

Autores: Maren, Marion J. van.
The reproductive cycles of Chaetogammarus marinus and Eulimnogammarus obtusatus in northern Brittany are compared, as well as the environmental conditions under which these gammarids live. Both species show reproductive activity throughout the year. The maximum rate of ovigerous ♀ ♀ was established for E. obtusatus in the months of February-March (the coldest period of the year), for Ch. marinus in December. The former species showed the lowest rate in August (the warmest month of the year) and the latter species in March. Eulimnogammarus obtusatus lives in the lower half of more exposed beaches and was rarely found on a substrate containing mud, contrary to Chaetogammarus marinus.

The purpose of the Nederlandse Groenland Expeditie 1975 was the study of Long-tailed Skua (de Korte, see page 6) and several species of waders (Bosman, see page 4) in the Scoresbysund region (East Greenland). In addition to skua’s and waders we studied breeding biology of geese in spring and growth and mortality of Arctic Tern chicks on Fame Øer in August. These studies were a continuation of previous work in the area (de Korte, 1973 and 1974). We choose another base than in 1973 and 1974 (Kap Stewart) and worked mainly near Kaerelv at the head of Hurry Inlet. Forty eight bird specimens belonging to 12 species were collected and skinned. The stomach contents have been preserved in spirits for subsequent examination.

Ecological aspects of the distribution of reef corals in the Netherlands Antilles
Provedor de dados: 16
Autores: Bak, Rolf P.M.
The vertical and horizontal patterns of the distribution of corals and coral reefs (to a depth of 90 m) are discussed in relation to the environmental factors: geomorphology of the bottom, available substrate, light, turbidity, sedimentation, water movement and temperature. There is a general pattern which is comparable to other well-developed Caribbean reefs. However, as in other areas variations are found, e.g. the depth and growth form of Acropora palmata will depend on the degree of exposure to water movement. There are strong correlations between the environmental variables and the occurrence of coral species and their growth form, the species composition of coral communities and the character of the coral reef. In some cases the relationship is not...

Recently I came across a portrait of Heinrich Bürger made when, as a secretary to Philipp Franz von Siebold, he visited Edo (now Tokyo) in 1826. This portrait is a rough sketch, and so far probably is the only portrait of him in existence. It was made by Watanabe-Kwazan (written also as Kwazan Watanabe after the western manner), an eminent artist, who, at that time, was also highly distinguished as a scholar of western thinking, a consequence of his Dutch learning. The present sketch was found in a collection of Watanabe's works owned by an old family, Kasuya by name, residing in the town of Kira in Aichi Prefecture. Watanabe's last place, Tabara, is located south of Kira beyond the Bay of Mikawa. Watanabe died there in 1841. Burger's biographic data...

As part of the Cooperative Investigations of the Caribbean and Adjacent Regions (Cicar-project) plankton sampling was executed from 1970 to 1973. The cruises 10, 11, 12, 13, 14, 18 and 19 explored the area around Aruba, Bonaire and Curaçao, where the samples 1-98 (collected from 7 april to 21 july) and 200-214 (collected from 13 November to 18 December) were taken. (Fig.1) The area off the Guyana’s was explored by the cruises 15, 16 and 17 where the stations 99-199 (collected from 23 August to 3 November) were taken. (Fig.2) The net samples taken during cruise 10-19 are from 0 to 6 meters; only during cruise 13 and 14 also samples at 10, 18 and 27 meters were collected. During the cruises 22 and 23, in 1971, some additional net samples were taken. The nets...

Teucrium scordium in de Amsterdamse Waterleidingduinen. Onder de naam Nepeta cataria werd in 1856 door F. A. Hartsen aan de „Waterleiding bij Leiduin” een exemplaar van Teucrium verzameld, dat aanvankelijk werd gedetermineerd als T. chamaedrys (VAN OOSTSTROOM in Gorteria 4, 1968, p. 44). Toen ik onlangs het materiaal van deze soort nog eens doornam, viel het mij op dat dit exemplaar veel sterker behaard was dan alle overige T. chamaedrys-exemplaren en dat de bladen zittend waren (bij T. chamaedrys gesteeld). Een nieuwe determinatie wees dan ook al spoedig uit, dat dit exemplaar niet tot T. chamaedrys, doch tot T. scordium behoort! De oude opgave van T. chamaedrys in de A. W.-duinen komt dus te vervallen; niet de vondst van 1954. Uit het gebied van de...

De Nederlandse meerval, Silurus glanis Linnaeus
Provedor de dados: 16
Autores: Boeseman, M.
Het hierna volgende overzicht over de Nederlandse meerval werd samengesteld, naar aanleiding van een verzoek bij monde van Dr. H. G. J. Bouquet, ten behoeve van het Ministerie van Landbouw en Visserij. Daar een dergelijk overzicht tot nu toe niet werd gepubliceerd, en vele gegevens van belang verspreid zijn in min of meer ontoegankelijke kranten en periodieken, leek het wenselijk deze in iets gewijzigde vorm hier te reproduceren. Ten overvloede zij vermeld dat, gezien de aard van de bronnen, ook dit overzicht wellicht geen aanspraak kan maken op volledigheid. Van de zeer omvangrijke groep der meervallen (ongeveer 2100 soorten) komt slechts een enkele soort in Nederland voor, en slechts twee in Europa (Silurus glanis Linnaeus en Parasilurus aristotelis...

On Cerocorticium P. Henn., a genus described from Java
Provedor de dados: 16
Autores: Jülich, W.
In 1899, P. Hennings described a new genus of ‘Thelephoraceae’, viz. Cerocorticium, based on two specimens collected by E. Nyman and M. Fleischer on Java. According to him these specimens represented two different species of his new genus. The descriptions Hennings gave of the genus and the two species are rather poor and incorrect. His diagnosis of the genus runs: ‘Resupinato-effusum, subgelatinosum, sicco ceraceum. Hymenium glabrum, laeve. Basidia conferta, subclavata, 2- sterigmatibus. Sporae ellipsoideae vel ovoideae, hyalinae.’ (p. 138, in reprint p. 40). In a short discussion he declared the genus to be quite different from any Corticium because of the permanently 2-spored basidia and distinct from Michenera because of the absence of paraphyses....

Pleistocene Rhinocerotidae of W. Europe with reference to the recent two-horned species of Africa and S.E. Asia
Provedor de dados: 16
Autores: Loose, H.
Palaeontology is too often odontology of necessity, the dentition being the most resistant part of the skeleton. When, as in the genus Dicerorhinus, the dentition can be a source of mistaken identity, we must look for species deter- mination based on complete skulls as referents. This leads to problems of ecology when seen in combination with the fluctuating Pleistocene vegetation belts. Some recent species are included to show similarities and dissimilarities within the group.

A unique case of mating behaviour in a Malagasy tree frog, Gephyromantis liber (Peracca, 1893), with observations on the larval development (Amphibia, Ranidae)
Provedor de dados: 16
Autores: Blommers-Schlösser, Rose M.A.
The mating act in Gephyromantis liber and in other species of this genus differs from all other mating behaviour patterns known in Anura. The male settles with the ventral side of his thighs on the shoulders of the female, and oviposition starts without delay. The assumption is made that the femoral glands of the male play a rôle in the short mating contact. G. liber is a small arboreal frog, which is widely distributed in the Malagasy central Highlands. During the rainy season the eggs are deposited in a gelatinous mass on leaves overhanging shady small shallow puddles, in which the hatching larvae drop. The embryo does not develop external gills, and hatches by the time the spiracle and the horny beak are present. The tooth formula of the full grown...

Bizotia Pierrot, a synonym of Campylopus
Provedor de dados: 16
Autores: Florschuetz, P.A.; Florschuetz-de Waard, J.
In a recent paper PIERROT (BIZOT, PIERROT &amp; POCS 1974) described the new genus Bizotia based on Paraleucobryum densifolium Thér. (THÉRIOT 1939). However, ROBINSON (1967) already made the presumption that Paraleucobryum densifolium should belong to Campylopus, notably C. argyrocaulon (C.M.) Broth. His conception of C. argyrocaulon was apparently based on MUELLER’s original description (MUELLER 1874) only, which includes a detailed description of the cross section of the costa. We examined part of the type collection of C. argyrocaulon (Wallis s. n., Colombia, NY) but this material, although MUELLER’s description is correct, does not exactly match the type material of Paraleucobryum densifolium (Troll 2144-2145, Colombia, PC-TH).

Autores: Coesel, P.F.M.
Subsequent to a previous publication (COESEL, 1974), an additional number of noteworthy records of desmids from the NW corner of the province of Overijssel is reported. The complex of Holocenic lakes and peatbogs of that area increasingly proves to be the richest site of desmids in the Netherlands at the present time. It is especially the very shallow, mesotrophic pools in quivering bogs which have repeatedly yielded records of species new for the Dutch desmid flora (such as Cosmarium hornavanense var. dubovianum, C. quasillus, and C. subbroomei). It is to be regretted, however, that there are clear indications of a depauperisation of the tychoplanktonic desmid flora owing to a deterioration of the waterquality. Some species in particular, such as...

Autores: Rookmaaker, L.C.
INTRODUCTION The first scientific description of the Komodo Dragon (Varanus komodoensis), given by P. A. Ouwens, appeared only as late as 1912. During some time following this event, but little information on the species became available and no specimens were captured. Only in 1926, an American expedition to the island of Komodo, led by W. D. Burden, for the first time succeeded in capturing alive two Komodo Dragons and in transporting these to the U.S.A. Both animals were received at the New York zoological garden on 11 September 1926. One of the specimens, a male, died on 24 November 1926; the other, of unknown sex, died on 19 October 1926 (Jones, 1965: 92). On 14 October 1926, a male Komodo Dragon was received at the Amsterdam zoological garden. It was...

The Goldfish intestine normally contains a large number of lymphocytes, many of them being present in the epithelial layer. After stimulation with antigen, the number of lymphoid cells does not increase, but the proportion of large pyroninophilic cells and plasma cells does.

A review of the genus Sympetalandra Stapf and its position in Caesalpinioideae
Provedor de dados: 16
Autores: Steenis, C.G.G.J. van.
A review is made of tribe Dimorphandreae and a new key is provided for the five genera belonging to it. The genus Brandzeia Baill. from Madagascar is discarded as it is founded on a mixture of different other genera. In the past insufficient attention has been paid to three characters which distinctly count in generic distinctions in this tribe, viz. the occurrence of pellucid glands in the leaves and flowers, whether the leaflets are alternate or opposite, and whether the floral parts are inserted on a epigynous, cup-shaped receptacle or whether this is absent. The genus Sympetalandra is found to be quite distinct from Erythrophleum, several characteristics remind more of Mora. The genus Sympetalandra is redefined and a key is provided for the distinction...

Parasitic mites of Surinam XXXIII. Feather mites (Analgoidea)
Provedor de dados: 16
Autores: Černý, V.; Lukoschus, F.S.
The mites listed in the present paper have been collected from July to October 1971 by the junior author and Drs. N. J. J. KOK during their stay in Surinam with financial aid of the Netherlands Foundation for the Advancement of Tropical Research (WOTRO). Mites have been collected occasionally mainly from birds, found dead on the roads, and from captured birds which died in the pet shop “Tropical Wildlife”, Paramaribo. As in many instances the hosts were decayed, few mites could be prepared. The relation of formerly described species to new species clearly shows our poor knowledge of parasites on birds from this region. Most of the species have been described by the senior author (ČERNÝ, 1974a, b, 1975). This paper contains descriptions of new Trouessartia...

A large number of samples of Salpidae, Doliolidae and Pyrosomatidae, collected by the U. S. Ocean Acre Project, are studied. A new record for the Bermuda area of Doliopsis rubescens (Vogt, 1817) is given. Dominant species are Iasis zonaria (Pallas, 1766), Salpa fusiformis Cuvier, 1804, and Salpa aspera Chamisso, 1819. Seasonal peak occurrences are observed for several species. The seasonal and vertical variation of the number of muscle fibres of aggregate Salpa fusiformis and aggregate Salpa aspera is studied and discussed.

Dr. Jan Theodoor Henrard, former curator of the Gramineae at the Rijksherbarium, died at Leiden 28 August 1974, in his 93rd year. Among the staff-members of the Rijksherbarium there are only a few left who have known Dr. Henrard, as he retired in 1946 on reaching the age of 65. They will remember him as an enthusiastic taxonomist with a great love for the variation of living nature. He was always busy analyzing the often very slight differential characters of importance in the family to which he devoted a great part of his life, the Grasses.

This paper is the first contribution to the knowledge of the freshwater sponges of Suriname. Four species have been identified up till now: Metania spinata (Carter, 1881), Trochospongilla paulula (Bowerbank, 1863), Radiospongilla crateriformis (Potts, 1882), and Drulia uruguayensis Bonetto &amp; Ezcurra de Drago, 1969.

A new species of Corynespora
Provedor de dados: 16
Autores: Loerakker, W.M.
In the course of investigations on fungi occurring on bark of deciduous trees, an unknown dematiaceous fungus was encountered. Because of its long, septate conidia, arising from the apex of dark conidiophores, the specimen was thought to represent an undescribed species of the genus Corynespora Güssow. This identification was kindly confirmed by Dr. M. B. Ellis, C. M. I., Kew.

Conidiogenesis and conidial septation as differentiating criteria between Phoma and Ascochyta
Provedor de dados: 16
Autores: Boerema, G.H.; Bollen, G.J.
New definitions of the form-genera Phoma Sacc. and Ascochyta Lib., based on developmental criteria, are presented. Phoma species show phialidic ontogeny. The first conidium is produced within a papillate protrusion of the undifferentiated parent cell; after a conidium secedes the basal part of the papilla remains as a collarette on the conidiogenous cell which may show two or three layers corresponding with the layers of the original papilla. The conidia secede by a three-layered septum and are in principle one-celled, although secondary septation may occur, especially in vivo (0-95%). In vitro under normal laboratory conditions the majority of conidia however always remain one-celled. The pycnidia are usually glabrous but also may be hairy or setose....

Een vondst van de trilgraszegge (Carex brizoides L.) in Drenthe. In 1973 werd, enkele km ten zuiden van Zuidlaren, in een droge sloot langs een bos Carex brizoides L. gevonden. De determinatie werd bevestigd door D. Bakker en D. T. E. van der Ploeg. De soort bedekt hier een oppervlak van ca. 3½ x 16 m. Gezien de standplaats (licht beschaduwd, iets voedselrijk) en de grootte van de groeiplaats is het niet aannemelijk dat de soort hier als adventief opgevat moet worden. Het betreft hier de tweede vindplaats in Drenthe van deze zeldzame soort.

The decimal scale for vegetation analyses of permanent plots Formerly for vegetation analysis of permanent plots the author used the modified scale of Braun-Blanquet with smaller intervals than the original scale. For calculations on the basis of coverage (e.g. of difference- and change quotients) the symbols of this scale have to be transformed in values proportional to the real coverage percentages. A transformation in very simple values is not possible; so calculations are time-consuming. It has become clear that for an efficient and exact analysis of permanent plots a scale is needed that fulfills the following demands: 1. The scale should be fine enough to register small changes in vegetation. 2. The symbols (numbers) of the scale should be...

The morphology and histology of the reproductive organs of Sagitta planctonis forma planctonis and of S. planctonis forma zetesios are described. No difference in number of oocytes was observed. The existence of a temporary oviduct is questionable. It may be possible that the so-called accessory fertilization cells are not actually participating in fertilization, but they may have a resorptive or secretory function.

The sergestid shrimp Lucifer in the 1970 CICAR plankton samples taken by H.M.S. “Luymes”, with notes on the Amazon river as nutrient source
Provedor de dados: 16
Autores: Troost, Dick G.
In accordance with previous works, L. faxoni was found to be abundant and L. typus scarce in the changing environment of the coastal waters off northern South America. High numbers of L. faxoni were present in two types of water, viz. highly saline coastal waters with high primary productivity due to enrichment by subsurface water, and in low-salinity lenses, isolated from the Amazon outflow. Low nutrient levels, as reported before from similar low-salinity lenses are presumed to be caused by increased mixing with infertile, though highly saline Guiana Current water, and depletion by primary producers which are consumed by the relatively large Zooplankton standing stock in these lenses, of which L. faxoni comprised the bulk.

Autores: Dennert, Henk G.
The variability of the morphological character on which the distinction between a brackish water and a freshwater subspecies of Gammarus duebeni is based, viz. the ratio merus width/merus length in the fifth walking leg, is studied. Evidence is given, that the merus dimensions only very partially can be correlated with the distribution and the ecology of G. duebeni. No clear clinal variation can be found in the merus dimensions in Europe. The subspecies G. d. celticus is found only in inland waters in Ireland and Brittany; the subspecies G. d. duebeni is found in western and northwestern Europe, and in Canada, in brackish water habitats and in some freshwater localities. Evidence is given, that G. d. duebeni has invaded the latter freshwater localities...

Recently a 9-page report was issued as a first step to establish a modest but effective station for all kinds of field work, amid the Gunung Leuser Reserves, on the bank of the Alas River. Some details about these Reserves, which together cover 6500 sq. km, have been sketched on pages 2185 and 2186 of Flora Malesiana Bulletin no. 27. The whole area is exceedingly rich in plant and animal life, and is also geologically interesting and varied. It would be the first station of its kind in Sumatra, situated at about 300 m altitude, with tops of 3000 m and higher within reach. Little ecological work has been done yet, except on orangutans, but collections of identified material of plants and animals, and publications thereon, are in existence, which means that...

Rhodobryum occurs on a steep part with a grade of about 30° of a north-facing hillside which borders the valley of the rivulet Geul. This steep part originated by specific land use for several centuries and it forms a part of a pasture which lies below it and is incidentally grazed by cattle. Above the locality a forest stretches towards the hill top. The habitat of Rhodobryum roseum receives no direct sunshine and the microclimatological situation can be defined as open shade.

Provedor de dados: 16
Autores: Klaver, E.
Rearing of Bourletiella pruinosa collected in the Dutch dunes, demonstrated that spermatophora are placed at random without any apparent mating behaviour. The spermatophora do not seem to have any attraction to the females. An aggregational behaviour, which would enhance the meeting of a spermatophore by a female, could not be demonstrated. The spermatophora are exceptionally resistant to dry and hot air for long periods. They are, contrarily, very sensitive to liquid water, but dew seems not to damage them in nature because they are often deposited on strongly absorbent substrates, notably lichens. A strong indication is found of the presence of two generations of this species. Females are not sexually neutralized, but attain their secondary sexual...

A sheet of the BSIP collections, gathered in Vanikoro Island, Santa Cruz group, near the proper Solomon Is., had tentatively been identified as probably belonging to Euphorbiaceae, but was discarded by Airy Shaw in 1962 and now again in 1974. Closer examination showed it to belong to Melicytus, a suggestion made by Dr. R. C. Bakhuizen van den Brink Jr. This genus is distributed in the West Pacific Islands, from New Zealand to Samoa; it was mapped by Van Balgooy in Pacific Plant Areas (2, 1966, 103). Though the specimen is male, we assume it to belong to Melicytus, not Hymenanthera. This represents a considerable extension of the generic area. Comparing the floral structure it is distinctly different from the Samoan form and also from M. ramiflorus Forst....

A new species of Gilmaniella from the soil of Kuwait
Provedor de dados: 16
Autores: Moustafa, A.F.
In the course of investigations on the fungal flora of the salt-marsh soils of Kuwait, a Gilmaniella species was isolated twice in 1973. Its smooth vegetative mycelium and large conidia with relatively wide germ pores indicated that it is sufficiently different from the only known species in Gilmaniella, G. humicola Barron (1964), to warrant its description as a new species.

Sea turtles nesting in Surinam
Provedor de dados: 16
Autores: Schulz, J.P.
PREFACE The first manuscript for this book originated in 1970 in the form of a revised translation of 'Zeeschildpadden in Suriname,, a mimeographed report written primarily for internal use. This English version was of the same hybrid nature as the Dutch booklet, which was meant to be a comprehensive general guide for visitors to the nesting beaches, as well as a publication of the results of local research. The present English version, which has grown to three times the size of the original, maintains this hybrid nature. Consequently this book contains sections on general taxonomy and on the biology of sea turtles, subjects which have been treated elsewhere in a superior way by more competent authors. This general information, which is included to make...

Callopora bathyalis n. sp., nouvelle espèce de Bryozoaire chilostome de l’Océan Atlantique nord-oriental
Provedor de dados: 16
Autores: Harmelin, Jean-Georges.
A new species of Callopora (Bryozoa, Cheilostomata Anasca), C. bathyalis n. sp., was discovered on Madreporaria from the bathyal zone of the Atlantic Ocean. Its main characteristic consists in an entire covering of the area by a calcified racketshaped plate joined to the proximal gymnocyst by a peduncle. This plate bears an avicularium and represents a highly modified avicularian chamber. This structure appears to be a striking adaptation to the deep habitat of this species. Its supposed function is to protect the frontal membrane from silt deposit.

Wood opals from Yakuplu, Turkey: their properties and genesis
Provedor de dados: 16
Autores: Buurman, P.
Fossil driftwood from Sarmatian (Late Miocene) gravel deposits near Yakuplu, Turkey, ranges between lignitic and opaline. Opalization occurred in various stages of decay. The stage of decay of the wood and the eventual admixture of detritic clay influenced the crystallinity and the dehydration characteristics of the opal. Opals influenced by the host rock seem to have montmorillonitic suprastructures. Opalization was probably the result of the weathering of volcanic ash layers in the overlying strata.

Contribution to the knowledge of the Amphipoda 68. Descriptions of two new species of the genus Ampelisca (family Ampeliscidae), along with a redescription of A. bouvieri Chevreux, 1913
Provedor de dados: 16
Autores: Karaman, Gordan S.
Three Ampelisca species (fam. Ampeliscidae) from Antarctic waters (Arthur Harbor, Anvers Island) are studied and described: A. anversensis n. sp., A. bouvieri Chevreux, 1913, and A. richardsoni n. sp. The specimens of A. anversensis are considered the Antarctic counterpart of the species A. macrocephala Liljeborg, 1852. A. richardsoni was hitherto confused with A. eschrichtii Krøyer, 1842. A new locality for A. bouvieri is established. In establishing differences between Antarctic populations (anversensis n. sp., richardsoni n. sp.) and North Atlantic populations (macrocephala, eschrichtii), the non-existence of bipolar Ampelisca species is proved.

The present review of the Asiatic freshwater puffers of the genus Tetraodon was thought necessary because the only preceding review (Le Danois, 1959) disregards some major taxonomic rules and methods. The material studied originates from existing museum collections and comprises type material of most of the species concerned.

The aggregate zooids of Salpa fusiformis Cuvier, 1804, S. maxima Forskål, 1775, and the group of the species S. aspera Chamisso, 1819, S. younti Van Soest, 1973, S. thompsoni Foxton, 1961, and S. gerlachei Foxton, 1961, show a difference in the arrangement of the oral musculature. Differences in the solitary zooids are less clear. Differences have also been found in the total number of muscle fibres of the oral musculature in the aggregate zooids of the genera Salpa and Weelia. The aggregate and solitary zooids of the genus Weelia can be distinguished on their oral muscles from those of the genus Salpa. The aggregate zooids of Salpa fusiformis show clinal variation in the number of muscle fibres of the oral musculature.

Aruba, Netherlands Antilles, is a 175 km² xeric island lying off the Caribbean coast of Venezuela. The flat coral and limestone regions of the shore contrast with the rolling hills that rise in the east to elevations of 188 meters. Vegetation types are varied. The island has excellent maps (LENS 1910, MEUTER 1963), and its natural history has been surveyed and described by various scientists, e.g. MARTIN (1888), BAKER (1924), WESTERMANN (1932), WAGENAAR HUMMELINCK (1940a, 1953), Voous (1955, 1957, 1959), STOFFERS (1956), DE BUISONJÉ (1974), while herpetological data have been published by WAGENAAR HUMMELINCK (1940b) and BRONGERSMA (1940, 1948).

Vergleich des agonistischen Verhaltens von zwei Gruppen Jungfischen (Haplochromis burtoni) gleichen Alters
Provedor de dados: 16
Autores: Bekkem, A.W.H. van; Bierhof, M.J.
When a batch of young of the mouthbreeding cichlid Haplochromis burtoni is divided into two groups of equal size, they show different behaviour. The ones that are caught first are less aggressive than the second, more shy ones. If agonistic behaviour has a positive selection value, it can be an important factor for the rapid speciation in cichlid fishes. In order to investigate this assumption experimentally, one has to bear in mind that early experience, group size and group density can influence the agonistic behaviour.

Provedor de dados: 16
Autores: Gradstein, Stephan Robbert.
The present study was initiated a few years ago by Dr. R. Grolle (Jena) who discovered that Acrolejeunea (Spruce) Schiffn. was probably the correct name for a tropical liverwort genus to which in this century the name Ptychocoleus Trev. was applied. Since replacing the name Ptychocoleus by Acrolejeunea would necessitate a considerable number of nomenclatural changes, I was asked to reexamine the taxonomy of the group. I soon found that Ptychocoleus as traditionally understood is heterogeneous and consists of two well-defined genera: Acrolejeunea (Spruce) Schiffn. and Schiffneriolejeunea Verd. (Gradstein 1974a). In order to determine their taxonomic affinities, I decided to review the generic subdivision of the subfamily Ptychanthoideae (Lejeuneaceae) to...

Hydrobiological observations in Surinam with special reference to the man-made Brokopondo Lake
Provedor de dados: 16
Autores: Leentvaar, P.
The construction of large reservoirs such as the man-made Brokopondo lake, is certainly not the result of proposals and conclusions of biological studies, but rather of political, technological and economical decisions without serious consideration of the biological implications. The biologist is faced with the results of a serious and hazardous intervention in the environment of man, animals and plants, which must be evaluated and if possible managed after planning and construction. Therefore it is a positive development that in recent years in more cases the ecological aspect of dam construction is integrated in the plans. In the case of Lake Brokopondo, officially called Prof. Dr. Ir. W. J. van Blommesteinmeer, long before the work was started the...

Light and electron microscopic studies of the ascus top in Sarcoscypha coccicea
Provedor de dados: 16
Autores: Brummelen, J. van.
The structure of the top of the ascus in live and fixed Sarcoscypha coccinea has been studied with different methods of light microscopy. Electron micrographs have been made of median sections of asci first fixed in 1.5% KMnO4, then postfixed with OSO4. Light and electron microscopy give somewhat different but supplementary information on the lateral wall and the top of the ascus in Sarcoscypha. In the ascoplasm a funnel and a funiculus have been found. The ascus wall consists of three layers. (1) An outer layer, which after different stainings is visible with the light microscope, corresponds with the two outer strata of the stratified electron-transparent layer, and is very thin in the top. (2) A middle layer, which is formed by the inner stratum of the...

De Harders Chelon labrosus en Liza ramada bij 't Horntje—Texel

Autores: Boer, P.
INLEIDING In 1970 werd gekonstateerd dat Liza ramada (Risso, 1826) (Mugil ramada) een zeldzame soort is en dat de vis die men voor L. ramada hield in werkelijkheid Chelon labrosus (Risso, 1826) (Mugil labrosus) blijkt te zijn (Boer, 1971). Chelon labrosus is dus de algemene soort, Liza ramada de zeldzame, die tot 1970 — althans in Nederland — alleen in zoet water werd aangetroffen. In 1971 werd het onderzoek naar harders voortgezet. Hiertoe werden bijna alle harders onderzocht die werden gevangen in de fuiken van het N.I.O.Z. bij 't Horntje (zuidpunt Texel). Uit dit onderzoek, dat van eind maart tot begin september 1971 plaatsvond, bleek dat Liza ramada niet zeldzaam is: 5% van de onderzochte harders behoort tot deze soort.

Note on the pollen morphology of Crypteroniaceae s.l
Provedor de dados: 16
Autores: Muller, Jan.
The pollen morphology of the genera Crypteronia, Dactylocladus, Axinandra, Alzatea and Rhynchocalyx is compared in view of a proposal to unite these genera in Crypteroniaceae. Three pollen types are recognized, differing in aperture and shape symmetry, but showing distinct similarities in exine and aperture structure. It is argued that the heterocolpate type found in Dactylocladus, Axinandra, and Rhynchocalyx and the bisyncolporate type characterizing Crypteronia, may both have been derived from a less-specialized tricolpate ancestral type which has been retained in Alzatea. The wider affinities of Crypteroniaceae are discussed and thought to be with Lythraceae and Melastomataceae, although a more remote relationship with Cunoniaceae s also possible.

Lepiota, Leucocoprinus and Leucoagaricus with a more concentrated development may occupy an intermediate position. Some remarks are made on developmental problems in Squamanita. In Chamaemyces fracidus the radiating elements on the cap are not a palisadodermium sensu stricto but they belong to the universal veil. However this structure is limited to the...

Of all plant families the Meliaceae is among the more useful to man, chiefly for its high quality timbers and for the ease with which some species can be grown in plantations. Almost confined to the tropics, its species nevertheless pervade them, and occur, often conspicuously, in a variety of habitats from rain forest to mangrove swamp and semidesert. For its size, the family probably contains a wider range of floral and fruit structures than any comparable group. In what other family is there such a diversity of primitive ‘arillate’5 seeds, side-by-side with such an array of derived fruits and seeds, and still connected by intermediates? Or, to take the flower, where else can be found such a diversity of forms, from the minute, but structurally complex,...

On the presence of Rana ridibunda ridibunda Pallas in the Netherlands
Provedor de dados: 16
Autores: Hoogmoed, M.S.
Since long there has been a dispute whether in the Netherlands there occur one or two species of green frogs of the genus Rana. There has never been any doubt concerning the presence of Rana esculenta Linnaeus, a species widely distributed throughout the country (Van de Bund, 1964, 1968). The first to mention Rana ridibunda ridibunda Pallas from the Netherlands were Van Kampen &amp; Heimans ( 1927), who observed that they saw a specimen of Rana esculenta var. ridibunda from Den Horn in the province of Groningen. Unfortunately they did not state where the specimen was deposited and no such specimen could be found in the collections of the Rijksmuseum van Natuurlijke Historie (RMNH) in Leiden or in the Instituut voor Taxonomische Zoölogie in Amsterdam. Since...

Taxonomic notes on Glenniea (Sapindaceae)
Provedor de dados: 16
Autores: Leenhouts, P.W.
1. The genus Crossonephelis Baill. (1874) is reduced to Glenniea Hook.f. (1862). The necessary new combinations have been made. 2. Crossotiephelis (Lepisanthes) palawanicus (Radlk.) Leenh. is reduced to Glenniea (Cnemidiscus) thorelii (Pierre) Leenh. 3. Melanodiscus sp. nov. Dale &amp; Greenway, formerly placed under Crossotiephelis africanus Leenh., appears to represent a different genus, probably new, possibly near Eriocoelum of the Cupanieae.

The RGM data bank programme for storage and retrieval of geological collection data
Provedor de dados: 16
Autores: Freudenthal, M.
The structure of the RGM registration system is discussed, with special attention to the costs for running this data bank, and for adding new information to it. The programme produces printed catalogues that offer a wide variety of entries into the collection. It is estimated that the entire registered collection of the museum can be transferred to the new system in about five years. Co-operation with other institutions may lead to a national data bank for geological collections.

Bijdragen tot de kennis der Nederlandse Desmidiaceeënflora, 2. Desmidiaceeën uit het Mosterdveen
Provedor de dados: 16
Autores: Coesel, P.F.M.; Hoogendijk, E.M.G.
The Desmidflora of the Mosterdveen (a complex of small fen soaks in the Netherlands province of Gelderland) provides a good example of a microphyte cenose characteristic of an oligotrophic type of water (as described by BEIJERINCK, 1926), which has in the meantime become very rare. The most typical indicator species found in the Mosterdveen are Cosmarium ralfsii Bréb., Micrasterias jenneri Ralfs, Euastrum crassum (Bréb.) Kütz., and Xanthidium armatum (Bréb.) Rabenh. Some species whose occurrence and distribution in the Netherlands is not so well known, partly owing to their problematic taxonomy, are discussed separately.

Biological results of the snellius expedition : XXVI. The Portunidae (Decapoda - Brachyura) of the snellius expedition (Part II)
Provedor de dados: 16
Autores: Stephenson, W.
INTRODUCTION In 1940 Leene published Part I of the Snellius portunids, with the stated intention of using the remaining material to produce monographs of the genera Thalamita and Neptunus (now Portunus). These monographs did not eventuate and at the invitation of Dr. L. B. Holthuis the material was made available for study by the author at the Rijksmuseum van Natuurlijke Historie in Leiden. The original intention was to report upon the collections of the Snellius expedition and upon the accrued specimens from the Indo-West Pacific area in the Leiden Museum which belonged to described species. It was then intended to publish separately upon the undescribed species in these and other collections. Instead these undescribed species are included in the present...

An annotated checklist of the lizards of French Guiana, mainly based on two recent collections
Provedor de dados: 16
Autores: Hoogmoed, M.S.; Lescure, J.
At the moment 36 species of lizards (6 Gekkonidae, 12 Iguanidae, 1 Scincidae and 17 Teiidae) are known for certain to occur in French Guiana. Of these 36 species, four are reported from that country for the first time (Anolis marmoratus speciosus Garman, Cercosaura o. ocellata Wagler, Prionodactylus argulus (W. Peters) and Tretioscincus agilis (Ruthven)). Moreover, there remain four species of which the occurrence in French Guiana is very likely and which presumably will be found when more lizards are collected by specialists. Eleven species were erroneously reported from French Guiana by various authors. The reasons for their removal from the list of French Guianese lizards are given. The zoogeographical conclusions of Hoogmoed (1973) remain valid,...

The Heteroptera of the Netherlands Antilles – X Berytinidae (Stilt Bugs)
Provedor de dados: 16
Autores: Štusák, J.M.; Cobben, R.H.
This paper is a further contribution to the knowledge of the Heteroptera of the Netherlands Antilles continuing the series on bugs of this region (COBBEN, 1960a, b; DRAKE &amp; COBBEN, 1960a, b; WYGODZINSKY, 1960; NIESER, 1967, 1969a, b; COBBEN &amp; WYGODZINSKY, 1975). It is based on the material of berytinids collected by the second author while studying the bugs of these islands. The material collected contained a total number of 65 specimens of Berytinidae divided into 3 genera and 3 species: Pronotacantha armata Stusak, from Curaçao; Aknisus multispinus Ashmead, from Bonaire, Aruba and Curaçao; Jalysus reductus Barber, from Saba, St. Eustatius and Curaçao.

Zoogeography and speciation in the Salpidae (Tunicata, Thaliacea)
Provedor de dados: 16
Autores: Soest, R.W.M. van.
This paper represents a general study of two major phenomena in the taxonomy of the lower taxa of the Salpidae and their bearing on theories about the origin of the recent species. Arguments are presented that point strongly to a specific status for closely related forms previously described as infraspecific by most authors. Latitudinalclinal variation, reported for the first time in salps in a previous paper of the present author, is now demonstrated to be a uniform trend in all species with a wide distribution into temperate waters. Some indications are found that support the assumption that the clinal forms represent separate populations with a small degree of genetic difference. Thalia democratica (Forskål, 1775) is divided into two formae, forma...

アルファルファの混播に関する研究 : 播種密度と混播割合が生育におよぼす影響
Provedor de dados: 19
Autores: 本江, 昭夫.
播種密度 (400、225、100 個体/m2) と混播割合 (アルファルファ100、75、50、25、0 %) が乾物生産におよぼす影響を明らかにするために、本試験を1974年5～9月に、帯広畜産大学付属圃場で行った。生育に伴う草丈、茎数、個体重の変化を調査すると共に、1番草刈取 (7月12日)、2番草刈取 (9月20日)の際、階層別乾物重、群落内の相対照度を測定した。 結果の概要は次のとおりである。 1) 密度が増すにつれ、相互遮蔽の影響を強く受けて個体当たりの分げつ数、乾物重は低くなったが、群落全体としての面積当たりの乾物生産量は高くなった。 2) 年間の総乾物生産量はアルファルファ単作区で有意に高い値を示し、混作区とオーチャードグラス単作区でほぼ同様の値を示した。 3) アルファルファの個体重の増加は茎数の増加よりむしろ、茎当たりの乾物重の増加により左右された。 4) オーチャードグラスの分げつ当たりの乾物重は0.1～0.2 gで一定に達し、個体重の増加は分げつ数の多尐により影響された。 5) 混作区の1番草において、アルファルファは常に群落の上層に葉層を展開させ、オーチャードグラスは下層に位置して生育は抑制されたが、刈取後、再生力の違いからアルファルファの葉層は低くなり、オーチャードグラスの生育は良好になった。 6) 高密度区は軽量の側に偏した個体重分布をもつ個体群により構成されていたが、密度が低くなるに従い正規分布型の個体群をもつ群落により構成されていた。 7) アルファルファの混播割合が増すにつれ、オーチャードグラスの粗蛋白質含有率は直線的に増加した。

Technological improvements for the cultivation of invertebrates as food for fishes and crustaceans: 1. Devices and methods
Provedor de dados: 27
Autores: Persoone, G.; Sorgeloos, P.
Technological problems can be considered as one of the bottlenecks of research concerned with culturing aquatic invertebrates in the laboratory, as well as the pilot and mass production stages. Oxygenation problems, circulation of the food and sedimentation problems can easily be solved by adapting the shape of the culturing vessels, i. e., by using funnel-shaped bottoms or high, narrow cylinders. In both cases, the food particles, settled on a very small bottle area, can easily be blown back into suspension using an air pump, which re-aerates the medium at the same time. A number of culturing devices for different categories of organisms, including algae are described and commented on. The only power source involved is compressed air which aerates, keeps...

The influence of the formulation of the herbicide paraquat on its toxicity for aquatic organisms
Provedor de dados: 27
Autores: Benijts-Claus, C.; Persoone, G.
Short term bio-assays have been carried out on representatives of different trophic levels of the aquatic food chain. The two wetters, which are included in the commercial formulation "Gramoxone" are very harmful for fish and their combination to paraquat increases the toxicity of the herbicide. Algae and crustaceans on the contrary, are more affected by the herbicide than by the wetters, the toxicity to the latter two groups being much higher than to fish.

Hibernation in the copepod &lt;i&gt;Halicyclops magniceps&lt;/i&gt; (Lilljeborg, 1853)
Provedor de dados: 27
Autores: Heip, C.H.R.
&lt;i&gt;Halicyclops magniceps&lt;/i&gt; (Lilljeborg, 1853) is an inhabitant of brackish waters along the European Atlantic coasts from Germany south, and of Algeria (Dussart, 1969). During five years of investigation of a shallow brackish water pool in northern Belgium, we found the species to be the only quantitatively important cyclopoid copepod. It shows a clear yearly cycle, with one prominent peak in summer (Heip, 1973). It appears at the end of April or the beginning of May, and disappears again in October or November. Because a previous investigation, carried out in summer, had shown that copepods do not occur below a depth of 3-4 cm in the sediment, samples were limited to the first five centimeters of the sediment and included a water column of...

Technological improvements for the cultivation of invertebrates as food for fishes and crustaceans: 2. Hatching and culturing of the brine shrimp, &lt;i&gt;Artemia salina&lt;/i&gt; L.
Provedor de dados: 27
Autores: Sorgeloos, P.; Persoone, G.
Although extensive fundamental research has been performed on the brine shrimp, the yields from hatching and culturing this organism which is widely used in mariculture, can be greatly improved. By exposing the immersed cysts to light and by using a new type of hatching cylinder and separator box, greater hatching and separation efficiencies can be obtained. Controlled mass culture of brine shrimp larvae to the adult stage has been extremely difficult until now; the literature on the subject is reviewed and a new technique of high density culturing at the pilot-stage is described.

&lt;i&gt;Polysiphonia banyulensis&lt;/i&gt; nov. sp. (section &lt;i&gt;Oligosiphonia&lt;/i&gt;) is a species with four pericentral cells, without any cortication. The isolated erect thalii have pseudodichotomous ramifications that are markedly narrower at their base: they originate in the axils of trichoblasts. These are very large and are characterized by the very large sub-basal cell. The phyllotaxis of the trichoblasts is 1/4 but the number of segments that occur between two trichoblasts is variable. The tetraspores occur isolated or in two contiguous segments in the upper half of the thallus. The male and female gametophytes are still unknown. Collected at Banyuls-sur-Mer, Pyrénées-Orientales, France in July 1974.

Belgian shrimp research in 1973
Provedor de dados: 27
Autores: De Clerck, R.; Redant, F.
In 1973 the commercial shrimp catches reached the very high level of 1615 tons. This represented the highest catch since 1956 and twice the landings of 1971 or 1972. The average engine-power of the vessels was 147.3 hp and the average catch per hour fishing was 23.6 kg. The catch curve shows the same pattern as the previous years, with a marked peak in October. This peak however was in 1973 (51 kg/ hour fishing) clearly much higher than in 1971 (33 kg/hour fishing) or in 1972 (30 kg/hour fishing). The experimental shrimp fishery was carried out by the &lt;i&gt;RV Hinders&lt;/i&gt;. On the fishing ground of the Westdiep five stations were monthly sampled with an otter trawl. The shrimp catches were divided into two length classes (smaller or larger than 54...

The effect of low lead and zinc concentrations on the larval development of the mud-crab &lt;i&gt;Rhithropanopeus harrisii&lt;/i&gt; Gould
Provedor de dados: 27
Autores: Benijts-Claus, C.; Benijts, F.
Low concentrations of Zn&lt;sup&gt;2+&lt;/sup&gt; and Pb&lt;sup&gt;2+&lt;/sup&gt; (up to 50 ppb) produce significant delay in the development of the estuarine mudcrab &lt;i&gt;Rhithropanopeus harrisii&lt;/i&gt; Gould. It is clear that the effect of lead dominates the effect of zinc with regard to the toxicity of a mixture of the two metals. Some combinations of the two metals, however, neutralize the toxic effect of lead and even accelerates the larval growth.

On the significance of aggregation in some benthic marine invertebrates
Provedor de dados: 27
Autores: Heip, C.H.R.
Populations of most benthic marine invertebrates show an aggregated spatial pattern. This has been shown to be the case for Foraminifera, Gastropoda, Bivalvia, Polychaeta, Oligochaeta, Nematoda, Copepoda, Ostracoda, Amphipoda and Isopoda. Only among the Bivalvia does there seem to be important exceptions to this rule. Evidence is presented that pattern formation is the result of two opposing forces: (1) the need for sufficient energy in which space is more evenly partitioned amongst individuals; and (2) the necessity for contact between individuals when copulation is part of the reproductive scheme. Since aggregation is the rule, the strategy in the majority of benthic marine invertebrates appears to be a reduction in the risk of failing to find a partner...

Nitrification in the Scheldt Estuary (Belgium and the Netherlands)
Provedor de dados: 27
Autores: Billen, G.
Nitrification and repartition of nitrifying bacteria were investigated in the autoepuration zone of the Scheldt estuary. Measurements of vertical profiles of nitrate and nitrite concentrations in the interstitial water of sediments show that nitrification in sediments is very low, implying that most of the nitrate and nitrate production occurs in the water of the river itself. Nitrifying bacteria, probably of terrestrial origin, are present throughout the water along a longitudinal profile of the estuary, with a regular decrease in numbers downstream. However, nitrification occurs only in a zone of favourable oxidation-reduction conditions, which coincides with the thermodynamic stability fields of nitrate and nitrite with respect to ammonium.

An account is given of the infralittoral phytobenthos (Rhodophyta, Phaeophyceae, Chlorophyceae) of Port-Cros Island (France). From 2 to 10 m depth, under calm conditions, up to 109 species were listed for each 400 cm² quadrat sample. It must be emphasised that these species numbers are considerable, and that the part played by algae in the photophilous settlements is conspicuous or even dominant.

Vertical distribution of nitrate concentration in interstitial water of marine sediments with nitrification and denitrification
Provedor de dados: 27
Autores: Vanderborght, J.P.; Billen, G.
Vertical concentration profiles of nitrate in interstitial water of sediment in the Sluice Dock at Ostend (Belgium) commonly show a maximum in nitrate concentration at a few centimeters depth where sediments are sandy and poor in organic matter, while in muddy and organic-rich sediments, nitrate is lower in interstitial water than in the overlying water and decreases rapidly with depth. Direct measurements of the activity of autotrophic nitrifying bacteria in the sediments show nitrification in the upper few centimeters of sandy sediments but not in muddy sediments. A mathematical model is proposed to analyze quantitatively these experimental results, taking into account nitrification, denitrification, diffusion, and sedimentation. Seasonal variations of...

FINANCING ASPECTS OF INVESTMENTS FOR POLLUTION ABATEMENT ON MICHIGAN DAIRY FARMS
Provedor de dados: 31
Autores: Baker,   Timothy G.
In recent years the condition of our physical environment has become an area of increasing public concern.  This concern has manifested itself in the form of legislated rules, formulated and administered by public agencies at the local, state, and federal levels, designed to control the use and degradation of the environment in a manner consistent with societal goals and objectives.  Of the forms of environmental degradation pollution of the air and waters has received particular attention. Agriculture has a number of sources or potential sources of pollution.  These include: (1)  human wastes from the farm (human) population; (2) crop residues; (3) food processing wastes; (4) dead animals; (5) agricultural chemical residues; and (6) animal wastes....

AN ASSESSMENT OF THE ROLE OF INSURANCE AND STRUCTURAL MEASURES IN FLOOD MITIGATION PLANNING
Provedor de dados: 31
Autores: Forsythe,   G.A.
There is no entirely satisfactory strategy to mitigate the risks associated with flooding. In Australia, reliance is usually placed on structural measures; however, an appraisal under different criteria highlights reasons for their inadequacy. Insurance is initially advocated as an alternative and appraised under similar criteria. It is shown to be a useful mitigation strategy, although somewhat limited in that it is merely a palliative to the flood problem. An alternative approach to flood mitigation is hypothesized which incorporates insurance as its base and utilizes other measures, particularly structural, where feasible. Such an approach is shown to effectively maximize the beneficial features of both insurance and structural measures. Problems...

FORECASTING CROP QUALITY
Provedor de dados: 31
Autores: Ryland,   G.J.
The need for a forecasting system of biological quality arises as a result of the price-quality payment schemes in grower and processor contracts which operate in many agricultural cropping industries. The seasonal nature of the series of vertical quality height gives rise to questions as to the repetitive pattern of the shape and trend translation of the series. These hypotheses can be tested using conventional statistical methods. For non-stationary series, however, a Box-Jenkins type dynamic seasonal model is proposed. These forecasting procedures are applied to a series of sugar cane quality.

PLANT PESTICIDE ECONOMICS WITH SPECIAL REFERENCE TO COTTON INSECTICIDES
Provedor de dados: 31
Autores: Longworth,   John W.; Rudd,   Don.
The energy crisis and the current world food situation have both drawn attention to the importance of off-farm inputs in high-technology agricultural systems. Plant pesticides are one of the most important of these off-farm inputs. The correct use of chemical pesticides requires a high level of managerial competence since the issues involved are extremely complex. The development of an integrated approach to the management of plant pests offers an alternative to the increasingly expensive chemical control techniques. Cotton production illustrates both the complexities of the management involved in plant pest control and the feasibility of developing integrated control strategies. Plant pesticides, especially insecticides, also create externalities. The...

ON THE USE OF DETERMINISTIC LINEAR PROGRAMMING FOR PLANNING IN A NON-CERTAIN ENVIRONMENT
Provedor de dados: 31
Autores: Nuthall,   Peter L.; Moffatt,   D.J.
Farm planning in the non-certain world is complex so that models which adequately represent this situation are difficult and expensive to experiment with. Thus a range of linear programming models based on simplifications has been suggested for planning under non-certainty. This discussion reviews the problem of farm system infeasibility which can arise from the Lise of these models and suggests an alternative approach.

A LINEAR PROGRAMMING SOLUTION TO SOME MARKET ALLOCATION PROBLEMS
Provedor de dados: 31
Autores: Piggott,   Roley R.
Certain market allocation problems involving linear average net revenue functions can be solved by linear programming. The technique can be applied to an objective function derived from linear marginal net revenue functions, the objective being to force each marginal net revenue as near to zero as possible given the constraint set. If a particular problem is suited to a linear programming solution, researchers may prefer to use this technique rather than more sophisticated optimization methods.

TEXTILE FIBRE SUBSTITUTION AND RELATIVE PRICES
Provedor de dados: 31
Autores: Minford,   Patrick.
The elasticity of substitution between textile fibres is investigated within a CES production function in which the fibres are grouped according to degree of substitutability. Disaggregated data for U.S. textile usage in the post-war period are examined and the elasticities estimated are generally above unity. The conclusion is reached that, while technical change and diffusion may have explained changing fibre shares in certain, usually specialized end-uses and contributed to the explanation in others, in most end-uses relative price change has been an important factor.

SUPPLY RESPONSE IN THE WHEAT-BELT OF SOUTH-EASTERN AUSTRALIA: THE IMPACT OF DELIVERY QUOTAS ON WHEAT PLANTINGS
Provedor de dados: 31
Autores: Fisher,   Brian S.
Supply response equations were estimated for a number of regions in south-eastern Australia using the area sown to wheat as the response variable. These equations were used to determine the effect of delivery quotas on the area of wheat sown in those regions. Results from this study indicate that delivery quotas were only effective in reducing wheat plantings in the south-eastern Australian wheat-belt in the 1970-71 season. Plantings in other seasons in which delivery quotas were applied could be explained using variables such as wheat prices and a time trend.

AN ECONOMIC ANALYSIS OF STABILIZING SCHEMES
Provedor de dados: 31
Autores: Subotnik,   Abraham; Houck,   James P.
The main purpose of this paper is to analyze the welfare implications of stabilizing consumption and production and to compare it with the already-known welfare implications of stabilizing prices. Two sets of assumptions regarding supply behavior will be considered: (1) supply reacts instantaneously to a change in market prices, (2) producers react to changes in expected prices and expectations are "rational" within the context developed by J.F. Muth.

A comparison between the cost of living of average wage earners in Sydney and nineteen country towns in New South Wales was carried out in 1974, assuming that expenditure on items of goods and services was distributed in the same proportion as in the Consumer Price Index in both country towns and the city. Housing, which was cheaper in the country, was the only group of major consumer expenditure where a significant difference between city and country town costs could be detected. The differences between the costs of food, clothing, services and miscellaneous items of expenditure in the city and country towns were not significant. A study using regression analysis revealed that there was a significant positive correlation between the size of country towns...

Sunflower Production Contracts: Provisions and Analysis
Provedor de dados: 31
Autores: Cobia,   David W.
Provisions of sunflower production contracts in North Dakota and Minnesota are summarized in this report. A procedure which can be used to compare the economic value of contracts is also presented. Extensive commercial production of sunflowers is relatively recent. Contracts provide growers with an assured market, guaranteed price, and assistance in proper growing practices. Processors and marketing agencies can better control quality and supply through contracts. The proportion of sunflower growers under contract has been declining as farmers become more familiar with the crop, because of expanding market outlets, and because several contractors wish to avoid costs of contracting. Sunflowers are contracted directly with contractors or through their agent...

Beef Versus Wheat Production in South Central North Dakota
Provedor de dados: 31
Autores: Krenz,   Ronald D.; Danielson,   Bernard G.
This project was initiated to determine what potential exists in North Dakota to expand livestock production without seriously affecting crop production. Also, there was interest in determining if various types of governmental agricultural programs would be needed or even useful in encouraging livestock production. Funding for this project was provided jointly by the Economic Research Service, U.S. Department of Agriculture, and the North Dakota Agricultural Experiment Station. This report will hopefully be useful both to producers in the study area and to public policymakers concerned with the grain and livestock economy.

LEAST-COST FEED RESERVE USING DROUGHT PROBABILITIES DERIVED FROM A GRAZING MODEL
Provedor de dados: 31
Autores: Thatcher,   L.P.; Lloyd,   Alan G.
An inventory model is used to determine least-cost fodder reserves for sheep in the Hamilton area of Victoria. Unlike earlier studies a grazing model is used to generate feeding requirements and thus allows for the gradual onset of drought and the associated rise in feed prices. Compared with studies based on probabilities of effective rainfall, the approach used measures more accurately the way in which drought incidence is affected by the seasonal pattern of pasture production in relation to animal requirements. The grazing model facilitates a study of the relative severity of drought at a range of stocking rates and a number of probability distributions are identified. The refinements achieved by using a grazing model also allow a more realistic...

The objectives of this report are to describe the structure of the slaughter hog marketing system in Michigan, and to investigate certain aspects of the market's performance.  Four aspects of market performance are discussed:  1)  the problem of accurate communication of supply and demand to producers; 2)  the problem of communicating carcass quality characteristics to producers in a way that promotes more effective production management; 3)  the ability of the market system to serve the varied production requirements of the different kinds of packers present in the state; and 4)  the ability of the system to promote an accurate refection of value to the buyer in the price paid to the producer.  This report also discusses ten methods of slaughter hog...

Among the different institutions through which the Costa Rican government influences production and internal marketing of agricultural commodities, the Consejo Nacional de Produccion (CNP) is the most important one.   The Consejo is given by law a great deal of authority in fomenting production and stabilizing prices of food products.  It is also entitled to perform a wide range of activities and marketing functions affecting the food system (buying and selling, assembling, transporting, storing and processing, importing and exporting, price fixing, input distribution, etc.).  Because of the strategic role of agriculture in the country, and due to very significant influence of the Consejo's intervention upon production, marketing and consumption in...

Because methods of eliminating aggregation bias are impracticable, an alternative method is suggested for reducing aggregation bias which uses regression estimates of farm resonrce availabilities as functions of farm size. The estimates are incorporated in a parametric run of the LP problem in which size is parameterized. The method is applied to a case study problem, and the results compared with other methods of demarcating representative farms.

PUBLIC POLICY ON CATTLE TICK CONTROL IN NEW SOUTH WALES
Provedor de dados: 31
Autores: Johnston,   Jim H.
An economic problem exists in the allocation of resources to cattle tick control. The decisions of private individuals on tick control are unlikely to result in a desirable allocatin from society's viewpoint because of market failure. Such market failure will be due to significant externalities, risk and economies of scale in cattle tick control and ignorance of tick control by producers. Government involvement is justified to achieve a better allocation of resources than would otherwise occur.  Choice of the desirable level of Government involvement and of the best control strategy will depend upon reduction of the decision problem to a choice between a combination of a small number of strategies and policy instruments and empirical evaluation of the...

The agricultural sector in Costa Rica, as in many other developing countries, has been playing an important role in the economic development of the country.  This sector presently contributes approximately 30 percent of the gross national product, generates 69 percent of the total foreign exchange, and employs 47 percent of the total labor force in the country.  Nevertheless, full use of labor is reflected in the form of open or disguised unemployment in the agricultural sector.  There are no reliable estimates of the magnitude of these forms of unemployment, but it is likely that underemployment or migration might have increased.  This underemployment of human resources has stimulated a greater migration towards the main cities, causing a disproportionate...

AGRICULTURAL CREDIT UTILIZATION AND PROJECTED NEEDS IN CANADA
Provedor de dados: 31
Autores: Charland,   Andre.
The technological and economic development at the beginning of the century started to disrupt that pattern but the real revolution took place after the Second World War.  During the past 20 years, the pace of change in agriculture accelerated and this trend will probably continue to accelerate during the seventies.  One of the results of this revolution is a tremendous need for capital which cannot be generated internally by the farm business.  Therefore, farmers have to rely more and more on credit.  In Canada, the principle provider of long-term funds for the farmer is a crown agency, the Farm Credit Corporation.  The important changes we saw in the past year are not heading toward a stop or a pause.  On the contrary, the acceleration of the last years...

The Institute of Agricultural Technology traces its history back to 1894 when Dr. C.D. Smith began a class in farm dairying at Michigan Agricultural College.  His purpose was to train people engaged in farming the art, science, and practice of milk production and buttermaking.  The purpose of the Institute of Agricultural Technology is to enable men and women to gain marketable skills.  Each program is eighteen months in length and includes classroom and practical work experiences.  During placement training, the trainees are offered the opportunity to put their knowledge and skills to work and practice -- in sum to "learn to do by doing."  In order to accomplish this, the directors and coordinators of the Institute of Agricultural Technology have...

Autores: Kim,   Chung Ho.
This paper attempts to analyze gaps between policy goals and policy results realized through process of policy implementation, and to investigate the obstacles which make such gaps.  Generally, policy goals are set up by central government with ambitions and detailed instruction, however, policy results turn out unsatisfactory when policy is implemented through central and local government units.  In connection with such happenings, as case study of a dairy cattle project in which a policy goal was to increase farm incomes, and policy results came out with 1) a large number of farms terminating their participation soon after they joined the project, and 2) poor farm management results among farms remaining in the project.

USING INPUT DEMAND AND PRODUCTION FUNCTION MODELS TO ASSESS THE NET BENEFITS OF DAIRY HERD IMPROVEMENT
Provedor de dados: 31
Autores: Ryan,   James G.
Two methods of evaluating (the net social benefits of the dairy herd-improvement scheme operated by the New South Wales Department of Agriculture are described. The first involves derivation of 'an input demand' function for the herd-recording aspect of the scheme and use of this function to estimate the economic surplus (net of both private and public costs) provided by the service. The second approach involves deriving a production function for milk from which it is possible to estimate the contribution herd-recording and artificial breeding have made to increasing milk yields per cow. Social benefits are shown to have been less than social costs for herd-recording, however dairy farmers have made net private gains. The herd-recording scheme has...

RESPONSE FUNCTION ESTIMATES FOR LOT FED BEEF
Provedor de dados: 31
Autores: Buffier,   B.D.; Freebairn,   John W.
The paper reports estimates of the short term response in the number of cattle placed on feed lots to changes in the prices of fat cattle, store cattle and grain. Data used in the analysis comes from interviews of a panel of feed lot operators regarding their intended 1974 throughput of cattle at different price combinations. Price combinations are identified at which no cattle would be placed in feed lots, at which feed lots would be used at maximum capacity, and at which price changes would induce changes in the number of cattle on feed. For the price responsive zone regression procedures are employed to estimate response price elasticities.

A CROSS-SPECTRAL APPROACH TO MEASURING PRICING EFFICIENCY IN THE NEW SOUTH WALES PIGMEAT MARKET
Provedor de dados: 31
Autores: Griffith,   Garry R.
This paper is concerned with determining the nature of and the relationships between movements in a number of New South Wales pig and pork price series. Spectral and cross-spectral methods are applied to some ten series differentiated by type of pig and market level. Results indicate that over the long term there are in general strong correlations between the various price pairings examined, but that in the shorter-run, price changes are not well reflected throughout the pig market. The role of imperfect information is noted as a major contributor to this observed short-run price independence.

Autores: Spriggs,   John.
There are three main parts to this paper. The first concerns the adaptation of conventional demand and supply theory to explain why and when the development of substitutes occurs. The second part is a discussion of four examples of substitutes that appear to have completed their developmental process. This is to see how the theory fares in practice. In the third part, implications of the theory are drawn for the beef industry which recently had its first serious encounter with substitutes.

TARIFF COMPENSATION: SUFFICIENT JUSTIFICATION FOR ASSISTANCE TO AUSTRALIAN AGRICULTURE?
Provedor de dados: 31
Autores: Harris,   Stuart.
This paper discusses in greater detail the case for tariff compensation set out in the Green Paper on Rural Policy. It considers a number of theoretical and practical arguments levelled against the principle, including those put forward in the Annual Report for 1973-74 of the Industries Assistance Commission. It concludes that despite the various counter arguments, the second best argument for tariff compensation applicable to low cost manufacturing as well as rural industries, remains valid in principle; in practice the extent to which any such partial compensation would be warranted needs to be assessed in the light of the appropriate substitution and complementarity relationships.

The basic objective of this report is to discuss the factors considered and the methods that are used by small-grain farmers in the marketing of their products. The figures and discussions which appear in this report are not meant to be an inclusive average of all farmers in North Dakota, but rather a consensus of specific groups of farmers engaged primarily in producing small-grains with limited income from other sources. It is hoped that this report will serve as a useful reference in helping North Dakota small-grain producers identify possible marketing alternatives and strategies available.

Provedor de dados: 31

Queensland Department of Primary Industries and University of Queensland Stochastic-computerised-activity-budgeting (SCAB) facilitates and extends the traditional gross margins analysis for sheep activities. SCAB is one of the very few computerised management aids so far developed for Australian farm management situations. In the deterministic mode SCAB calculates gross margins based on point estimates of all the relevant parameters. In stochastic mode it generates a distribution of pay-offs (gross margins) based on the manager's subjective probability distribution for the relevant major uncertain paramaters. The variance of this distribution of pay-offs represents a measure of the risk associated with the activity given the manager's current knowledge and...

Irrigation by private development has been increasing in North Dakota and will continue in the future. The question many ask is what effect does this type of development have on the surrounding business community? Capital for the purchase of the irrigation system and the increased income and expenditures of an irrigation-type agriculture are spent largely in the local community. This study was undertaken to determine the effect on the business community in southwest central North Dakota of irrigation development. The work was done cooperatively by the Agricultural Economics Departments of the Agricultural Experiment Station and the Cooperative Extension Service, North Dakota State University. It is hoped this report will serve as a useful guide in...

Autores: Ribeiro,Maria de Nazaré Góes; Santos,Antonio dos.
Resumo No período de março de 1973 a setembro de 1974 foram desenvolvidos estudos no ecossistema Campina Amazônica para caracterização microclimática de um solo arenoso com sua vegetação natural em equilíbrio biológico. Estes estudos envolveram medidas da temperatura do solo em três diferentes situações ecológicas na Campina, temperatura do ar e umidade relativa na Campina e na Campinarana. Foram observadas as seguintes amplitudes médias para a temperatura do solo: solo descoberto (areia) 16.7°C; solo semicoberto (areia sob líquen) 8.8°C; solo coberto (sob vegetação) 6.1°C. Para temperatura do ar esta amplitude na Campina foi da ordem de 20.3°C e na Campinarana de 14.0°C, enquanto que a umidade relativa oscilou entre 81-90% na Campina e 91-97% na...

Chromosome Studies of Brazilian Ferns
Provedor de dados: 36
Autores: Tryon,Alice F.; Bautista,Hortensia P.; Araújo,Izonete da Silva.
Abstract Chromosome numbers, habitat and general geographic distributions are reported for a sample of ferns from the vicinity of Manaus. These numbers are compared with those reported for species in other regions. The report of n=ca. 154 for Schizaea incurvata is the first record of the genus in the American tropics and the others are first counts of these species in continental South America. In Lindsaea n=42 and n=ca. 84, are somewhat lower and appear to represent a line distinct from the species of the paleotropics with n=47. In Trichomanes n=32, 64 and 128 appear to be levels of polyploidy based on X=8, while n = 72 is possibly based on X=9 and suggest possible diverse lines in the genus. Pityrogramma calomelanos with n=116 is considered as an...

The correct name for Castanha de cutia (Couepia edulis (Prance) Prance - Chrysobalanaceae)
Provedor de dados: 36
Autores: Prance,Ghillean T.
Abstract In 1972 the author described the new species Acioa edulis (Chrysobalanaceae) to name the Castanha de cutia, a plant which is economically important because of its edible fruit. The original description was based on fruiting material only. Recently collected flowering material has shown that the original generic assignment was incorrect, and so it is now transferred to Couepia the correct genus, and the flowers are described for the first time.

Resumo Primeira tentativa para determinar a magnitude do fluxo de água subterrânea, a fim de estimar o potencial de elementos biologicamente importantes no ciclo de nutrientes no ecossistema Campina Amazônica. O fluxo saturado da água, dentro do lençol freático, foi estudado por 2 métodos, no período de dezembro de 1974 a janeiro de 1975: 1) aplicando-se a equação de Darcy; 2) usando-se um traçador 3h (100 mCi) na forma de 3H2O. As variações apresentadas pelos dois métodos foram provenientes da alta permeabilidade do solo arenoso, propiciando rápidas variações do lençol freático, totalmente influenciado pelas precipitações pluviométricas. Ambos os métodos apresentaram resultados da mesma ordem de grandeza, indicando a existência de um movimento horizontal...

Resumo As principais fontes de nitrogênio na água do solo do ecossistema Campina Amazônica são: o material em decomposição (litter), chuva, água de lavagem da floresta e produtos do metabolismo de microrganismos. Foram analisadas amostras de água colhidas do lençol freático em quatro locais no solo de areia branca (Regosol), com relação aos compostos do nitrogênio (amônia, nitritos e nitratos), e calculadas as concentrações de nitrogênio orgânico e total. O nitrogênio de origem orgânica apresenta concentração superior às demais frações analisadas; o nitrogênio amoniacal, como principal produto de desdobramento do material orgânico vegetal por microrganismos, aparece em segunda escala de grandeza, enquanto que nitritos e nitratos estão quase sempre ausentes...

Provedor de dados: 36
Autores: Prance,Ghillean T.; Arias,Jorge R.
Abstract A field study of the floral biology of Victoria amazonica (Poepp.) Sowerby (Nymphaeaceae) was made for comparison with the many studies made in cultivated plants, of Victoria in the past. In the study areas in the vicinity of Manaus, four species of Dynastid beetles were found in flowers of V. amazonica, three of the genus Cyclocephala and one of Ligyrus. The commonest species of beetle proved to be a new species of Cyclocephala and was found in over 90 percent of the flowers studied. The flowers of V. amazonica attract beetles by their odour and their white colour on the first day that they open. The beetles are trapped in the flower for twenty-four hours and feed on the starchy carpellary appendages. Observations were made of flower temperature,...

The history of the INPA capoeira based on ecological studies of Lecythidaceae
Provedor de dados: 36
Autores: Prance,Ghillean T.
Abstract The Lecythidaceae of a 2500 m2 area of the secondary forest of INPA was studied. The 97 individuals of Lecythidaceae present indicated a high number of primary forest species. It is concluded that most of the area was not burnt when the original forest was cut, and the regeneration of primary forest species is much greater in areas which are not burnt over after felling. This is further supported by parallel studies of Bignoniaceae and Meliaceae of the same area.

Autores: Anderson,Anthony B.; Prance,Ghillean T.; Albuquerque,yron W. P. de.
Resumo Na Amazônia, na região do rio Negro, os solos de areia branca dispersos com sua vegetação associada, conhecida como campina amazônica, podem ter influência considerável sobre a ecologia total dos sistemas de rios de água preta. Este trabalho apresenta uma descrição da vegetação lenhosa de uma campina amazônica e de sua campinarana associada. Para que essa vegetação seja melhor interpretada, os autores opinam em considerá-la dividida em dois tipos: campina e campinarana. A campinarana, por sua vez, é subdividida em dois subtipos: campina aberta e campina sombreada. A estrutura e a composição da vegetação de cada tipo ou subtipo foram estudadas com detalhes. Com base no testemunho de sua vegetação, os autores concluem que a campinarana representa uma...

Final report on studies of nutrient cycling on white and black water areas in Amazonia
Provedor de dados: 36
Autores: Stark,N.; Holley,C.
Abstract Studies were conducted near Manaus, Brazil in cooperation with INPA to try to establish how nutrient cycling influences the formation of black water and white water. The studies measured the rate of decay of Caryocar villosum leaves on spodosol and oxisol terrestrial and aquatic sites when the leaves were untreated, and treated with a bacteriostat, or insecticide or fungicide. It also measured litter, animal populations, and the elemental content of ten biologically important elements in soils and decomposing litter. Results show considerable differences in the rates of decay and the agents and end products of decay which indicate that black water and white water formation are closely tied to the rate and type of decay and to basic soil types and...

Autores: bandel,G.; Carvalho,F.J.P.C.; Crocomo,O.J.; Sharp,W.R.; Gutierrez,L.E.; Carvalho,P.C.T.
O cultivo de explantes de folha de cafeeiro enriquecidos com hormônios mostrou que a partir de tecidos diferenciados ocorre uma desdiferenciação. Essa desdiferenciação alcança diferentes níveis devido, provavelmente, a fatores ambientais, e não genéticos. Observou-se nos calos obtidos uma variação nos padrões de diferenciação celular. Pro-embrióides e vascularização (Fig. 1), células gigantes (Fig. 4) e outros padrões de diferenciação (Figs. 2 e 3) foram observados. As células em cultura diferenciaram-se sem perder as potencialidades genéticas iniciais do embrião, do qual derivaram; mudanças ambientais e nos mecanismos de regulação gênica são responsáveis pela variação fenotípica observada. Explantes de caules de café produziram calos que diferenciaram-se...

Estudos sobre a nutrição mineral do cafeeiro: XXXI - influência do cobre do substrato no crescimento e composição mineral do cafeeiro (Coffea arabica L.) var. Mundo Novo e Catuaí
Provedor de dados: 43
Autores: Andrade,V.M. de M.; Lourenço,R.S.; Muraoka,T.; Malavolta,E.
A sensibilidade das variedades Catuaí e Mundo Novo ao nível de cobre no substrato foi estudada em condições controladas. Em solução nutritiva verificou-se que a primeira variedade parece ser mais resistente à toxidez. Ensaios com três tipos de solos mostraram que a elevação do pH a 6,5 e a adição conjunta de matéria orgânica neutralizam a toxidez correspondente a 200 ppm do elemento no meio.

Emprego de herbicidas do grupo das uréias substituídas na cultura da cenoura (Daucus carota L.): II - efeitos dos herbicidas sobre a cultura
Provedor de dados: 43
Autores: Lucchesi,Antonio Augusto; Simão,Salim; Minami,Keigo.
Foi realizado no Campo Experimental do Setor de Horticultura da ESALQ, Piracicaba, um experimento no sentido de verificar os efeitos de linuron, clorobromuron e cloroxuron sobre a cultura da cenoura. Foram testadas as dosagens mínima e máxima recomendadas pelos produtores dos herbicidas, em pré e pós-emergência das plantas daninhas. Os herbicidas não interferiram na parte aérea da cenoura. Em geral, os tratamentos em pré-emergência deram maior produção de parte aérea, raízes e raízes comerciáveis que os tratamentos em pós-emergência. Tanto o linuron como o clorobromuron deram bons resultados, sem interferir na produção, enquanto que a dosagem mínima de cloroxuron deu menos produção, devido ao pequeno controle das plantas daninhas.

Provedor de dados: 43
Autores: Abrahão,Ibrahim Octavio; Marconi,Arary.
Estuda-se a possibilidade da aplicação prática do método analítico na determinação da grandeza da indicatriz ótica de anidrita, cujo desenvolvimento teórico foi realizado por ABRAHÃO e MARCONI (1975). Os valores de λ e de µ λ, necessários à obtenção de Ng, Nm e Np, foram calculados por diversos processos diferentes e os resultados comparados. Concluiu-se que os valores de λ são muito discrepantes. Quanto a µ λ = (Ng - Np)/2, obtiveram-se resultados praticamente constantes, para todas as vias de cálculo utilizadas. Os autores concluem, finalmente, que as determinações de Ng, Nm e Np são inviáveis na prática, em face da extrema precisão que seria exigida das medidas de birrefringência, necessárias ao desenvolvimento do método e impossíveis de serem...

Autores: Abrahão,Ibrahim Octavio.
Estudam-se os modelos de cristalização de cloreto de cobre obtidos na presença de extratos de sementes de feijoeiro (P. vulgaris L.). São descritos e comparados os modelos obtidos em 11 séries de cristalização, com 5 repetições. Os fatores de variação envolvidos são: 3 variedades (roxinho, pintado, preto), 2 procedências (solos e solução nutritiva), 2 processos de obtenção de extrato (sementes secas e sementes úmidas) e 3 concentrações (0,05:0,5; 0,025:0,5 e 0,025:0,75). A conclusão principal é que o cloreto de cobre produz modelos de cristalização característicos e específicos para extratos de sementes de feijoeiro. Menos específicos são os efeitos de variedade c procedência, embora alguns caracteres possam ser assinalados.

Analisaram-se o desenvolvimento e a produtividade de progênies de cafeeiros de porte reduzido pertencentes aos cultivares san ramon, caturra e são bernardo, na região montanhosa de Monte Alegre do Sul. Tomou-se como padrão a progênie n.° 662 do cultivar burbom vermelho, de porte médio. Usou-se o delineamento em blocos ao acaso, parcelas subdivididas, com quatro e uma planta por cova em cada parcela a fim de avaliar a reação de 18 progênies nessas duas modalidades de plantio. De modo geral as progênies tiveram altura pouco maior quando plantadas a quadro mudas. Os dados de produção de café maduro no período de 15 anos indicaram que apenas algumas progênies não mostraram diferenças de produção quando plantadas a uma ou a quatro plantas por cova, enquanto...

A variedade de algodoeiro IAC 13-1 foi desenvolvida a partir da linhagem norte-americana Acala 5675, conhecida como uma "Acala Oriental", a qual foi selecionada de material primitivo colhido no México. Dadas as boas qualidades da sua fibra, essa linhagem foi objeto de estudos, na Seção de Algodão do Instituto Agronômico, desde a sua introdução. Após nove anos de aclimatação e seleção individual, foi isolada a linhagem IAG 61/60 como material promissor. Desenvolveu-se a IAC 13-1 a partir dessa linhagem por seleção genealógica, no período de 1961 a 1970. A sua semente foi entregue em 1968, pela primeira vez, para multiplicação em campo básico. A IAC 13-1 substitui a IAC 12-2, na lavoura, a partir de 1970, tendo maior produtividade, melhor capulho, maior...

Um novo tipo de algodoeiro foi isolado de uma população híbrida originada por cruzamento entre as espécies alotetraplóides Gossypium hirsutum L. v. latifolium Hutch, e G. barbadense L. v. brasiliense Hutch. A metodologia empregada e as principais características econômicas e morfológicas do novo algodoeiro são descritas e discutidas. Um ciclo de cruzamentos "intra", realizados na segunda geração após o retrocruzamento, seguido de seleção individual nas progenies desses cruzamentos, levou à obtenção de heptalobatum. O material não apresentou sinais de esterilidade, nem tendência a degenerar na descendência. Seu nome se deve às folhas, que, no estádio de completo desenvolvimento, apresentam sete lóbulos delgados. £ intermediário entre os pais para vários...

El hombre, en todas las ??pocas de la historia, ha tendido a objetivizar lo que consideraba como sobrenatural con s??mbolos de su propia creaci??n o con la reproducci??n de los ??rganos instrumentos.     El art??culo aborda la interpretaci??n del s??mbolo encontrado en la ciudad de Otavalo, dando a conocer c??mo los abor??genes ecuatorianos, con cierta claridad de expresi??n, esculp??an la fuerza productora de la naturaleza en lo que concierne o la procreaci??n humana. Aquel pueblo, que no se encaminaba a tientas en pos de la cultura, rend??a fervoroso culto a la divinidad f??lica como gestora de la fecundidad femenino y dispensadora de la buena suerte.

Qu?? es el estructuralismo (Especial para Sarance)
Provedor de dados: 122
Autores: Rodr??guez Castelo, Hern??n.
Se realiza un acercamiento al estructuralismo desde su surgimiento por  Ferdinand de Saussure, ???el lenguaje no es ni una forma ni una sustancia???,  explicando su evoluci??n y concepci??n frente al complejo fen??meno ling????stico.     Es un movimiento heterog??neo que inicialmente aparece como una metodolog??a cient??fica que pretende elaborar teor??as objetivas y verificables, a trav??s del control cient??fico a las ciencias del esp??ritu. En el estructuralismo el hombre pasa de ser sujeto de la historia y de la cultura, a ser objeto que se conoce por la objetividad y la neutralidad cient??fica, los "estructuralistas" tienden a estudiar al ser humano desde fuera, como a cualquier fen??meno natural, y no desde dentro, como se estudian los contenidos de...

Autores: Instituto Otavale??o de Antropolog??a.
En funci??n de los conceptos de zonas geo-culturales y formaci??n social  se debe  dise??ar un m??todo que parta de la observaci??n de las zonas geo-culturales, pero no de una observaci??n cualquiera sino de una que est?? informada por la experiencia y la teor??a general. A partir de esta observaci??n se retroceder?? en la historia para fechar los fen??menos observados y, finalmente, se volver??a al presente para completar el diagn??stico y poder fundamentar las pol??ticas adecuadas.

Constantes y variantes en la etnomusicolog??a y folklore
Provedor de dados: 122
Autores: Coba Andrade, Carlos.
Se realiza un informe  investigativo sobre la etnomusicolog??a, basados en  hip??tesis de la llegada del hombre a Am??rica procedente de Mongolia, por el Estrecho de Bering. Definida la Etnomusicolog??a como el estudio del pueblo, de sus m??sicos, como hechos de cultura-oral-tradicional.  Se exponen principios irrefutables, mientras no se pruebe lo contrario; sin embargo, se llega a la conclusi??n de que  es casi imposible llegar a la certeza de la etnomusicolog??a en las culturas pre- colombinas por el hecho de las variables a la constante en las diferentes ??pocas de una cultura determinada.

Ecuatorianismos y colombianismos : notas al diccionario de Luis Lalinde Botero

El art??culo hace referencia al libro aqu?? comentado lleva el t??tulo de Diccionario Jilos??fico Paisa, (Editorial Delta, Medell??n 7966, de Lalinde Botero en el cual el autor juega con el inventario de unas seiscientas palabras colombianas, especialmente antioque??as, desde el  folclor y el humor de la cultura paisa. Su estilo no deja de ser ??gil y libre. Los motivos paisas consagrados en personajes t??picos de la monta??a antioque??a surgen traviesos del trazo limpio y elocuente de este maestro del dibujo, al representar con rasgo tan preciso como burl??n lo que en el texto se define y comenta, se divulga y festeja con libertad y alegr??a.
