A "ucuúba" como fonte de celulose para papel.

Autores: MELO, C. F. M. de; SOUZA, H. B. de; LOUREIRO, M. R. C.; WISNIEWSKI, A.
Reunindo excelentes características, a madeira de Ucuúba (Virola surínamensis (Rol) Warb) tem sido extensivamente empregada na fabricação de laminados. Como consequêncía do processo produtivo, a madeira que não pode ser integralmente aproveitada, deixa um apreciável resíduo que, a falta de melhor emprêgo, não tem tido outra utilizaçãc senão como combustível na própria Usina. Estudando-se a ucuúba como fonte de celulose para papel, conclui-se que se trata, na verdade, de excelente matéria: prima, mesmo os resíduos de laminação que se constituem de restos de madeira de várias idades; Podem ser produzidos papéis Kraft de bôa qualidade, em ambos os casos, embora quando se trate da utilização dos resíduos de laminação as características de resistência ao...

O levantamento foi executado segundo normas adotadas pela DPP no que diz respeito a metodos de trabalho e classificacao dos solos. O levantamento realizado foi do tipo reconhecimento, sendo que na maior parte da area foi possivel faze-lo em nivel categorico inferior, porem em outras areas, devido as dificuldades de penetracao e ao intrincado arranjamento das unidades, foi usado nivel categorico mais elevado, isto devido a escala do mapa final que e de 1:600.000. Baseado no mapa de solos, foi possivel fazer-se dois mapas de avaliacao da aptidao agricola dos solos, segundo dois sistemas de manejo: Pouco Desenvolvido e Desenvolvido (sem irrigacao).

A traditional activity on the Breton coast, spider crab fishing has grown more important over the past few years, not due to an increase of the number of catches but to a significant decrease in the number of lobsters and crayfishes brought to the market, following the closing of some fishing areas (Anglo-Norman Isles, Ireland, England) and the exhaustion of others.

Autores: Mascle, Jean.
In a previous article published in the "cahiers Océanographiques" XXII, 1 (January 1970), pp. 25-32, I described the broad lines of subactual sedimentation in and around the canyon of Toulon. This data had been collected during a drilling cruise conducted in October 1967. Out of the 41 successful drillings, 17 had enabled the collection of rock samples representing, either the Maures basement in which the canyon of Toulon is cut, or more recent deposits, episodes of the eustatic or tectonic variations of the water level over the Quaternary and maybe the Pliocene era.

Le rapport présenté par le CNEXO sur ses activités au cours de l'année 1971 s'efforce de montrer comment l'action de l'organisme s'est insérée dans un contexte général caractérisé par une accélération sensible des développements industriels en mer. Le plan adopté qui diffère de ceux des rapports précédents (1968-1969-1970), cherche à présenter de façon particulière dans la partie intitulée "Effets d'une politique d'incitation", certains aspects des activités de coordination du CNEXO et des résultats que l'action de l'organisme a permis d'atteindre au cours de l'année 1971. L'année 1971 a en effet été marquée par un certain nombre de succès remportés par l'industrie océanique française, notamment en matière d'équipement de l'exploitation pétrolière, dans la...

Recherches sur le germon - Campagnes 1970 de "La Pelagia"
Provedor de dados: 5
Autores: Aloncle, Henri; Delaporte, Francis.
De nombreuses campagnes de recherches sur les thonidés et plus particulièrement sur le germon ont été faites depuis 1950. Elles ont d'ailleurs donné lieu à diverses publications et notamment à l'établissement d'une carte montrant l'apparition et les déplacements du germon en début de campagne.   Ces recherches ont été reprises systématiquement en 1967 après la mise en service de "La Pelagia", navire spécialement équipé pour cette étude. Les travaux entrepris à bord se situent sur trois plans :   a) aide directe à la pêche par la recherche des concentrations de thons, ces prospections s'effectuent essentiellement à partir de l'examen des conditions hydrologiques des secteurs étudiés ;  b) marquages systématiques des thons blancs et, éventuellement, des...

Examen microscopique des huitres plates de l'estuaire du Belon
Provedor de dados: 5
Autores: Herrbach, Bernadette.
Samples of oysters, Ostrea edulis, collected from badly decimated beds in the Belon estuary in July 1969 and July 1970 were examined microscopically in an attempt to determine the cause of death. Although large numbers of ciliates belonging to the ancistrocomidae were found in the digestive mass, no sign of any parasitic or viral disease was found in the tissues. On the other hand, oysters in poor condition exhibited a hypersecretion of mucopoly-saccharides covering the whole surface of the gastric epithelium. This condition, and the existence of a massive infiltration of the connective tissue and the blood sinuses by hyaline haemocytes, indicates a defense reaction against some unknown changes in the physico-chemical environment.

Autores: Cavanie, Alain.
In a previous article (1969), the author demonstrated, through the use of a hydrostatic model and of the Boussinesq hypothesis, the importance of some non-linear terms in the formation of inner fronts; this model provides a criterion for the easing and intensification of the slope of a simple wave according to the wave's upshore conditions. In this article, the use of a regular perturbation method enables us to free ourselves both from the long wave hypothesis and from the Boussinesq hypothesis. The theoretical model we created demonstrates the importance of non-linear terms in the formation of secondary oscillations upshore from the front. A phenomenon which was extensively observed in the eastern part of the Gibraltar straight. As the parameters of the...

Sur une affection parasitaire de la glande digestive de l'huitre plate, Ostrea Edulis Linne
Provedor de dados: 5
Autores: Herrbach, Bernadette.
During the summer of 1968, an abnormal mortality rate struck the flat oyster, O. edulis, raised in the upstream part of the Aber Wrach, a ria of Brittany's north coast. During the autumn, the phenomenon expanded steadily and progressively reached the various sectors of the estuary up to its mouth. Losses often reached and exceeded half the stock of oysters of all ages that were held there. The molluscs that survived, whether they were left where they were or transferred to other oyster-farming areas, had a deficient look characterised by a lack of growth, paleness of the digestive gland and an often very marked weight loss. On the weakest ones, the parasite flagellate Hexamita sp. was frequently found. In January 1969, changes similar to those noticed in...

Recent data on the western Mediterranean basin (Joides cruise, Montadert et al., 1970, Auzende et al., 1971, Le Borgne et al., 1971) and its connection with the evolution of the Atlantic area (Le Pichon et al., 1970, Talwani et al., 1971, Le Pichon et al. in writing) lead us, like other authors (Dubourdieu, 1962, Stanley and Mutti, 1968, Ryan, 1969 amongst others) to admit the theory of an opening of the Algero-provencal basin during the Cenozoic era. A series of arguments drove us to formulate the hypothesis of an Oligocene age (in process). This work is in line with this perspective. [...]

Recherche des pesticides organochlores dans les milieux littoraux
Provedor de dados: 5
Autores: Fougeras Lavergnolle, Jean.
Contamination from pesticides worries hygienists, who fear that content levels will rise in food to the point of causing incidents. The use of pesticides is becoming more generalised, for they have been found in noticeable concentrations in the marine environment, where they have even caused accidental mortalities of animal life, following a treatment against parasites along a riverbank. Thus, shrimp mortalities were observed along the South Carolina coast a few days after a heptachlor treatment (SOUDAN). Many authors, especially BUTLER and DAVIS, agree on recognising that organochlorines are the most toxic pesticides; DDT is one of the most toxic. BUTLER (1966) has shown that oysters are very good detectors of organochlorine pesticides, which they...

1 - The authors study and compare the biovolumes of 69 samples taken with the Isaacs-Kidd midwater trawl during the Polymède expedition on the N. O. "Jean Charcot" (May and June, 1970) in the western Mediterranean and in the vicinity of Cap Finisterre.  2 - The authors, having assembled the measurements of physical oceanographers, have prepared a diagram of the deep-current issuing from the Mediterranean into the Atlantic North- East. It is possible to superimpose on this diagram the route used by the young albacore (Thunnus alalunga) during their annual summer migration. This correspondance suggests an inter-relation between the two phenomena provided by intermediate trophic levels.  [NOT CONTROLLED OCR]

Etude microbiologique des mortalites d'huitres plates, Ostrea edulis L., de la riviere Belon
Provedor de dados: 5
Autores: Gras, Paul.
A microbiological study of the water and substrate in the Belon River was carried out during the summer of 1967, when the stocks of cultured oysters suffered very high mortalities. At the same time as the oyster mortalities there were dramatic decreases in the numbers of organisms, such as the diatoms and dinoflagellates, in the water. The numbers of bacteria, on the other hand, both in the water and in the surface layers of the substrate, reached very high levels, particularly amongst the anaerobic forms. It seems that the death of most of the organisms and the proliferation of the bacteria was due to the arrival of highly saline and cold water, which was rich in nutritive salts and poor in dissolved O sub(2). The augmentation of this water by organic...

Autores: Deltreil, Jean-pierre.
In a previous study, we gave an account of the impact that the development of gill disease had on Portuguese-oyster farms in the Arcachon basin. The interest of these observations was being able to capture the magnitude of the phenomenon from the time it appeared and to single out the immediate consequences; they were, however, limited in time and incomplete because they affected only three-year-old subjects born on site and already, for the most part, marketable. Indeed, the footprint of the disease that we had taken from that year on the spat itself made us fear the longer-term consequences; they could only be appreciated based on young individuals affected from 1967 on and monitored to the end of their stockbreeding. It was, moreover, desirable to...

Digestive glands of Ostrea edulis affected by an epizootic have been examined by light- and electron- microscopy. Round, compact lesions in the digestive gland cells contain refractive elements staining slightly blue or red with Geimsa. Ultra-structurally, each lesion contains (a) dense cytoplasma, without mitochondria and with paracrystal-line inclusions, (b) enclosed regions with vacuolar cytoplasm, no mitochondria and two types of formation; one is opaque, the other a vacuole containing ribosomes, lamellar structures and peripheral ovoid particles. The nature and significance of these structures is not known.

Autores: His, Edouard.
L'espèce Crassostrea gigas a été introduite en 1969 à titre d'essai par de nombreux ostréiculteurs du bassin d'Arcachon. La comparaison des vitesses de croissance de cette nouvelle espèce et de l'huître indigène C. angulata est nettement à l'avantage de l'huître japonaise. Cette dernière atteint la taille marchande dans la plupart des cas dès la première année d''immersion dans la baie alors qu'il faut généralement de deux à trois ans pour obtenir le même résultat avec l'huître portugaise.

Western extension of boundary between european and iberian plates during the pyrenean orogeny
Provedor de dados: 5
Autores: Le Pichon, Xavier; Sibuet, Jean-claude.
The kinematics of the Eocene episode of compression between the Iberian and European plates is examined. It is proposed that the boundary between the two plates extended West of the Pyrenees, along the Spanish marginal trench to end West of King's trough at a triple point junction. The pole of relative rotation computed within this hypothesis lies near 5°N ; 62°W and the resulting shortening along the Pyrenees is about 50 km dong 45°E. [NOT CONTROLLED OCR]

Depuis 1954, les pêcheurs de la côte ouest des Etats-Unis utilisent des tambours enrouleurs pour leurs chaluts de fond traditionnels. Cette méthode a permis en particulier de réduire le nombre des hommes embarqués, tout en augmentant leur sécurité. Il est habituel de voir dans ces conditions, des chalutiers de 20 à 25 m et de 400 à 500 cv avec des équipages de 3 à 4 hommes.   Ces dix dernières années, le chalutage pélagique à un ou deux bateaux s'est développé chez les riverains de la Mer du Nord. La technique a abouti à l'utilisation de chaluts très grands, mesurant jusqu'à 150 m de long et possédant des mailles de 300 et 400 mm de côté à l'entêture, donc encombrants et difficiles à manier.

Comments on the evolution of the north-east atlantic
Provedor de dados: 5
Autores: Le Pichon, Xavier; Sibuet, Jean-claude.
It has been proposed that the opening of the Bay of Biscay occurred by rotation about a pole situated near Paris (50.0° N, 3.3° E) and not about the pole proposed by Bullard et al.(4) (43.6° N, 1.0° E). The rotation about the first pole results in strike-slip motion aIong the North Pyrenean fault during the pre-Upper-Cretaceous opening, while the rotation about the second pole results in compression there. The second rotation is not compatible with geological data(5) which indicates extension prior to Upper Cretaceous in the Pyrenean region. We wish to show how these two hypothetical rotations agree with the magnetic data of Williams and McKenzie(6). [NOT CONTROLLED OCR]

Croissance, condition et mortalite des huitres du Belon
Provedor de dados: 5
Autores: Marin, Jean.
Growth rate, condition and mortalities in groups of oysters in oyster-beds in the Belon River were studied during 1968 and 1969. The growth rate up to the beginning of the summer was higher in 1969 than in 1968. Variations in the condition of the oysters during the 2 summers were related to the state of development of the reproductive organs and this sexual development was earlier in 1969 than in 1968 because of a sudden rapid rise in temp. Whereas relatively mortalities occurred during 1968, many oyster beds in the River Belon were decimated during 1969. The phenomenon responsible for these mortalities apparently occurred at a particularly critical time; when the oysters were growing rapidly and when most of them were at an advanced stage in the sexual...

Autores: L'Herrou, Roger.
Statistics on the pilchard fishery in the Bay of Biscay are given. In this area in 1967 a biological study was undertaken of adults, eggs and larvae. Breeding areas have been better defined. Breeding occurs in winter and spring and the fish are stenothermic when breeding. Zones yielding most eggs and larvae may bear no relation to the supposed areas of origin of fish with different mean vertebral counts. It was thought that each main region of the Bay (Armorican massif, Aquitanian basins and Cantabrian region) had its own race, but this may not be so, and the racial significance of the vertebral mean should be re-investigated.

At a neap tide, an attempt was made to follow the quantitative and qualitative nycthemeral variations in a planktonic population under the influence of the tide. Simultaneous study was made of changes in the physical medium and the biological material present. Physical measurements at 4 depths, of salinity, density, and speed and direction of current, were made every hr and eventually correlated with plankton samples made at 2 hourly intervals. Physical results are shown in graphs and tables and an analysis given of the zooplankton studied. Examination of the biovol obtained by sedimentation revealed a greater density of organisms at night, copepods forming the principal component of the plankton. Further studies were made of the copepods, various groups...

Autores: Bonnet, Marc; Duclerc, Jean; Pichot, Paul.
The great size of the continental shelf, the low landscape of the coasts, the lack of a sailing channel, are factors which make the precise localization of a ship on the bank of Arguin difficult, if not impossible. As a result, the data on the topography, though important, is still incomplete or imprecise. It is almost non-existent for the wide and shallow central shelf located inside the reef area where dangerous sailing adds up to these measuring difficulties. Filling these gaps is needed if we want to continue the exploration of this region and the assessment of the stocks. Concerning the nature of the seabed, a spreading of the sand towards the open-sea is observed, which is the direct consequence of the nearness of the desert, the action of the winds...

In al1 these methods, the pinger essentially gives knowledge of the precise instant of contact with the bottom, and the length of time the dredge or trawl works on it.

Le genre Staurosoma will (copépode parasite d'actinies) en mer rouge
Provedor de dados: 5
Autores: Laubier, Lucien; Schmidt, Hajo.
The members of the genus Staurosoma Will, 1844 are Copepods gallicol, parasites of Actiniae. The genus currently consists of two species, Staurosoma parasiticum Will, 1844, parasite of Anemonia sulcata Pennant, 1766 (= Actinia viridis) from the Mediterranean coasts (Will, 1844), in the Cape of La Hague area (English Channel) and the Gulf of Marseille (Caullery and Mesnil, 1902), and S. caulleryi Okada, 1927, parasite of Nemanthus nitidus (Wassilieff, 1908) (= Sagartianitida) in the Bay of Sagami in Japan. De Zulueta (1911) created for this unique genus the family Staurosomidae, a family that some more recent authors relate to Copepods Chondracanthidae. An update of the current knowledge was provided by Bouligand (1966), who details the differences between...

Etude sur les affections branchiales de l'huitre plate Ostrea edulis (Linne)
Provedor de dados: 5
Autores: Gras, Pierre; Herrbach, Bernadette.
Lesions in the gills of the oyster, Ostrea edulis, from natural populations in Mont Saint-Michel Bay have been studied microscopically and in tissue culture. No evidence was found of the presence of the protozoans which have been thought to cause similar lesions in Crassostrea angulata. On the other hand, structures were found which closely resemble various stages in the life cycles of Labyrinthomyxa marina and Dermocystidium marinum, fungi which are thought to be responsible for mortalities of Crassostrea virginica in the USA.

Environnement et mortalite des huitres plates de la riviere de Belon (1961-1970). Donnees generales
Provedor de dados: 5
Autores: Marteil, Louis.
Before 1960 the normal level of mortality of oysters maintained in beds in the Belon river during the summer was in the region of 15%. During several years in the period 1960-1970 much higher mortalities, up to 70% of the stock, were experienced. The circumstances of these mortalities and the appearance of the oysters themselves indicated that no parasitic disease or physiological deficiency was involved. 2 possible caused for the mortalities have been suggested, pollution or a sudden change in the physico-chemical environment. Although some industrial pollution of the River Belon occurs, This is very slight and the oyster beds most affected have been the ones furthest from the source of pollution. Similarly, the River Aven, which has a common mouth with...

Ecologie, croissance et regeneration, teneurs an acide alginique de Laminaria digitata sur les cotes francaises de la Manche
Provedor de dados: 5
Autores: Perez, René.
A study of L. digitata was carried out over the period 1965 to 1970. Monthly examination of marked plants showed that there was no single period of growth during the yr although in the third year a phase of activity giving rise to an increase in the size of the lamina and fronds was evident. Ageing of the alga was associated with a progressive reduction in meristematic tissue. A study of a `deep' population, never uncovered by water, was also carried out and although these showed similarities to the populations on the shore, there were quantitative differences, the size of plants in the deep population being very large. The effects of temperature and light on the alga's growth were examined in an attempt to determine the cause of this inequality in...

Pêche électrique en mer
Provedor de dados: 5
Autores: Le Men, René.
La pêche électrique a déjà fait l'objet de recherches dans de nombreux pays depuis plusieurs années. Si, en eau douce, elle est fréquemment utilisée, du moins par des services officiels comme les Eaux et Forêts, pour permettre le dénombrement des poissons de lacs ou de rivières, la capture de saumons ou de truites en vue de leur marquage ou pour détruire certaines espèces prédatrices, il n'en est pas de même en mer où les problèmes rencontrés sont beaucoup plus complexes.  En dépit de ces difficultés, des essais ont été tentés et le sont encore, principalement en Allemagne, en U.R.S.S., aux Etats-Unis. etc. Les travaux exécutés dans ces pays ont porté, soit sur les poissons pélagiques, soit sur la pêche au chalut des crevettes ou des poissons de fond.

Autores: Marteil, Louis.
From the studies conducted in 1968 and 1969, it becomes clear that there was a relationship between the flat oyster mortalities that occurred during the summer in the Belon and Merrien rivers and the appearance of a hydrological phenomenon primarily characterised by an overhang of abnormally cold water. Because the events recorded in July 1970 confirm the data already acquired, we will summarise the observations made on that occasion by MARIN, PAULMIER OR GRAS.

Autores: Durand, Henri.
La recherche d'une méthode de dosage rapide des matières grasses dans le poisson se trouve justifiée par l'emploi éventuel d'une telle méthode par les industriels de la transformation des produits de la mer. En effet, la teneur en graisse est un facteur déterminant de la qualité du produit et de la façon de le travailler. En vue d'un contrôle de matière première, les qualités essentielles de la méthode utilisée doivent être la rapidité, la simplicité et si possible, un prix de revient raisonnable, même si la précision n'atteint pas celle des mesures de laboratoire, souvent longues à effectuer.  Diverses méthodes ont été décrites. Nous les avons passées en revue et en avons testé quelques unes.

La peche du merlu et de la dorade a la Rochelle analyse des statistiques d'effort de peche et de production des annees 1966, 1967 et 1968
Provedor de dados: 5
Autores: Guichet, Roget; Gueguen, Jacques; Guillou, Alain.
For about ten years now, there has been a consensus of opinion in denouncing the impoverishment of trawlable sea beds in the European Atlantic. Long before, the Institute of Fisheries had drawn attention to the deterioration of certain stocks, in particular that of the hake (LETACONNOUX, 1951), and recommended conservation measures such as increasing meshing or creating containment areas. Nowadays scientists are no longer the only ones aware of the severity of this problem, because professional fishermen are also becoming aware of it as they see their own catches worsen year after year. However, when we try to get a more general idea of the situation, we only have available, in most cases, production statistics that are often incorrect. In the absence of...

Essai de synthèse paléoclimatique

Autores: Pastouret, Léo; Chamley, H.; Gaudry, I.
The drill samples collected during the Térébel expedition show some interesting characteristics. First, these samples have been taken from the sedimentary cover at depths of around 40 m, never attained through classical drillings in this area of the Mediterranean Sea; secondly, they have been the focus of a shared study between different disciplines. It seemed interesting to gather in a synthetic chapter the paleoclimatic results provided by palynology, the study of argillaceous minerals and planktonic foraminiferae. Considering, on the one hand, the shortness of the drill samples and the low density of the samples taken from these cores, and, on the other hand, the lack of a precisely-dated reference level, we had to be extremely cautious with our...

Observations préliminaires sur la reproduction des huîtres dans le bassin de Marennes-Oléron en 1971
Provedor de dados: 5
Autores: Gras, Paul; Comps, Michel; David, A.; Baron, G.
During the summer of 1970 mortality started in the Marennes-Oléron Basin which affected successively adult oysters, 18 year-old oysters and then the oyster spats collected the same year. Only the Portuguese oyster (Crassostrea angulata) was dying whereas the Pacific oyster (Crassostrea gigas) showed total resistance. The abnormal fixation of the 1970 spats, followed by an important mortality in this latter, and the large decrease of adult oyster stocks, and therefore of genitors, were also a reason for oyster farmers to worry as the new reproduction season was about to start. Some measures had to be taken in order to compensate for the lack of genitors susceptible of producing a tough and vivacious spat. The good results obtained for a few years with C....

Etude physico-chimique de l'estuaire du Belon
Provedor de dados: 5
Autores: Marin, Jean.
The Belon oyster farming centre, despite its economic interest, has, up to now, only been the subject of periodic investigation. In 1923, HINARD took on the study of oyster farm beds in order to compare them with those of another well-known area, Marennes. Later, within the framework of oyster larvae research, VOISIN (1932), TACLET (1935) and HERMAN (1935 to 1938) engaged in a few observations there on temperatures and densities during the months of June and July, the flat oyster's breeding period. In 1946-1947, in brief, MARTEIL started a comparative study of the Aven and the Belon, the results of which were not published. The recurrence of the phenomena of summer mortality rates, since 1961, made it necessary to acquire more knowledge of the estuary. Our...

Autores: Arbault, Suzanne; Lacroix, Nicole.
This research work was undertaken in 1964, within the more general context of study programmes of the Institute of Science and Technology of Maritime Fishing on teleosteen fish eggs and larvae and the relationship of egg-laying areas with hydrology. Since their catch is a significant contribution to the country's economy (15,000 tonnes of sardines in 1967, 6,000 in 1968, 8,000 in 1969 and 4,427 of anchovies were caught the same year), it seemed necessary to specify the breeding conditions of these fish and the location of their breeding grounds, then to try to forecast fishing stocks. In this research work, we will study more particularly the year 1968, which seems to us very representative and we will compare the results with those of 1964, 1965, 1966...

Les loisirs sont maintenant intégrés dans tous les schémas de prospectives économiques car ils consomment des revenus, du temps, des espaces et entrent donc dans le processus économique. A partir de l'instant où une activité existe, celle-ci engendre une demande à laquelle répond une offre ; il existe donc un marché des loisirs en général, avec ses problèmes de prix et d'équilibre et un marché spécifique pour chacune des activités de loisirs, car la notion de loisir...

Les apports nutritionnels des océans, à l'exclusion des vertébrés (poissons, reptiles, mammifères)

Autores: Laubier, Lucien.
Après une période de croissance rapide depuis la seconde guerre mondiale, l'exploitation des ressources vivantes des océans est stabilisée depuis quelques années entre 60 et 65 millions de tonnes par an, pour l'ensemble des océans. Ces chiffres recouvrent l'ensemble des produits tirés de la mer, qu'il s'agisse de vertébrés ou d'invertébrés, d'animaux ou de végétaux. De même, la distinction entre produit de la pêche et produit de la culture ou de l'élevage n'est pas faite. En réalité, si les poissons représentent une partie importante de ce total, l'homme exploite également la plupart des groupes zoologiques d'invertébrés marins, quelques reptiles et les mammifères marins (cétacés et pinnipèdes), et des algues (en particulier des algues rouges et des algues...

The analysis of cores taken during the drilling operation of the Terebel's cruise in the northwestern Mediterranean Sea has put into evidence some reworked sediments. However, the occurence of Gtobigerina pachyderma, Gtoborotatia truncatutinoides and Hyalinea balthica gives a quaternary age to these deposits (not older than Sicilian). The microfauna variations in some cores are related to paleoclimatological changes. Some of the sedimentary levels were deposited during a warming interglacial period. [NOT CONTROLLED OCR]

Autores: Deeleman-Reinhold, C.L.
A NEW SPECIES OF SULCIA In 1962, Dresco described the first representative of the genus Sulcia from the Greek mainland, Sulcia lindbergi. Recently, Brignoli (1968a) considered this species a subspecies of Sulcia cretica Fage. The genus is also known from Dalmatia, Hercegovina, Montenegro, and some adjacent islands (Kratochvil, 1938) and from the Island of Crete (Fage, 1945). In January 1969, my husband P. R. Deeleman, had the opportunity to visit the Koutouki Cave near the village of Ljopessi (officially also called Peania), situated at approximately 20 km west of Athens. This visit was made possible by the assistance of Mrs. A. Petrochilos and Mr. A. Kanellis, to whom we feel very much obliged. In this cave a new species of Sulcia was collected. The cave...

Pollenmorphological notes on the genus Dimocarpus (Sapindaceae)
Provedor de dados: 16
Autores: Muller, Jan.
The pollen morphology of all 5 species of the genus Dimocarpus was studied. General pollen morphology is rather uniform and only one main type is present, which could be subdivided into 7 subtypes on minor differences in shape, aperture, and exine pattern. Intraspecific variability is present in some species. Morphological trends are established and related to the taxonomic subdivision. Taxa which are macromorphologically advanced appear to have developed also derived pollen subtypes.

Three Upper Carboniferous, limestone-rich, high-destructive, delta systems with submarine fan deposits, Cantabrian Mountains, Spain
Provedor de dados: 16
Autores: Graaff, W.J.E. van de.
In the eastern part of the Cantabrian Mountains, northwestern Spain, Upper Carboniferous strata crop out. In the Pisuerga area an Upper Moscovian (\u2248 Westphalian D) limestone-rich sequence is exposed in a number of structural units. Correlations between the various structural units are based on lithostratigraphic characteristics and paleontological dating with fusulinids and calcareous algae. The various limestone units show rapid lateral transitions into siliciclastic deposits. The siliciclastic deposits are mainly interpreted as deltaic deposits. Three distinct delta systems are distinguished which, like the recent Rhône delta, are all of the wave-dominated, high-destructive type. The oldest delta system is associated with important turbidite...

Rattus dammermani Thomas, 1921 is known from southwestern Celebes. Rattus toxi Sody, 1941 is a subjective synonym of that taxon. Although the name dammermani has been listed in the literature as a subspecies of R. rattus, it is actually a valid species that is morphologically more closely related to R. rattus than to any other species of Rattus known from Celebes.

New records of the Holothurians Thyone serrifera Oestergren (Dendrochirotida) and Leptosynapta bergensis (Oestergren) (Apodida)
Provedor de dados: 16

During a student trip to the Trondheimsfjord (Norway) in August and September, 1967, eight specimens of this species were dredged off Kivnæbnes (63o 32' Ν, 9° 51' E), from a depth of 50 to 200 m, bottom clay with shells. The calcareous ossicles in the body wall are exactly like the illustrations in Østergren (1898) and Mortensen (1924: 235). Figures 1 to 3 show copies of figures by Østergren and Mortensen, and a drawing made from one of my preparations. Thyone serrifera seems to have been found only once before (pers. comm.

The systematic position of tribe Paropsieae, in particular the genus Ancistrothyrsus, and a key to the genera of Passifloraceae
Provedor de dados: 16
Autores: Wilde, W.J.J.O. de.
The members of tribe Passifloreae of the Passifloraceae are assumed to be originally all tendril-climbers. They have essentially axillary cymose inflorescences, and the vegetative ramification occurs always through the accessory bud. In tribe Paropsieae and Flacourtiaceae (mostly shrubs or trees, no tendril-climbers) the inflorescences are axillary, most likely essentially racemose, and the vegetative ramification is mostly through the axillary bud. The tendril-climbing neotropical genus Ancistrothyrsus appeared to belong to Passifloreae. Though the tribe Paropsieae remains to occupy an intermediate position between Passifloraceae and Flacourtiaceae, they can best be classified with the Passifloraceae. A new key is proposed for the distinction of both...

The distally lobed inner integument of Hernandia peltata Meissn. in DC. (Hernandiaceae)
Provedor de dados: 16
Autores: Heel, W.A. van.
A peculiar structural detail, occurring during the development of ovules, seems to have passed almost unnoticed till the present day. It concerns the distal rim of either the outer or the inner integument, which appears to be slightly lobed in the ovules of several unrelated plants. In a recent note (1970) I called attention to this feature. It is known from Juglans and Platycaria (Warming, 1878; Leroy, 1955; Boesewinkel and Bouman, 1967), where the single integument is two-lobed. Warming mentioned two more cases, namely Lagarosiphon and Symplocarpus; however, I cannot confirm his observations from dried material. I noticed it myself in Scyphostegia horneensis, in Caloncoba welwitschii, and in Sterculia alexandri. In these three species the lobes occur at...

Alternanthera paronychioides St Hil. (Amaranthaceae) in Indo-Malesia

During a study of species of Alternanthera Forsk. introduced in the Netherlands it was necessary to compare the Malesian representatives of A. ficoidea (L.) R. Br. ex Griseb. ssp. bettzickiana (Regel) Backer (Fl. Mal. I, 4, 1949, 91). The material under this name present in the Rijksherbarium, Leiden, proved to be heterogeneous, part of it belonging to another species. Dr. Van Steenis pointed out to me an article by Pedersen (Kurtziana 14, 1967, 437), where A. paronychioides St. Hil. was mentioned for Malesia, and showed me his correspondence with the author, where further details concerning this species were given. A closer study showed the unidentified specimens to belong to that species.

Ophistodonta Langerhans ist die einzige Gattung der Unter familie Eusyllinae, bei der der Pharynx-Zahn auf der hinteren Hälfte des Pharynx liegt.

Zaadkieming en licht
Provedor de dados: 16
Autores: Veen, R. van der.
The faculty of light-sensitive (photoblastic) seeds to survive in the soil in an imbibed state for many years and to germinate when exposed to light is ecologically important for many plant species, among them most annual weeds. Only a part of the seeds of these species will germinate after disturbance of the soil in which they are present. Of equal ecological importance is the induction of secondary dormancy in both photoblastic and non-photoblastic seeds by far red irradiation. In white light filtered through green leaves the ratio red/far red shifts considerably to the far red side. Consequently in a wood seeds of many species will be prevented from germinating, but when a clearing is made they soon germinate. As examples are mentioned the seeds of the...

Octocorallia from North-Western Madagascar (Part II)
Provedor de dados: 16
Autores: Verseveldt, J.
INTRODUCTION In the preface of the first part of the series "Octocorallia from northwestern Madagascar" (Verseveldt, 1969) I mentioned that Dr. Arthur G. Humes, Boston University, Massachusetts, U.S.A., made a rich collection of octocorals from the waters north-west of Madagascar, and that he kindly entrusted this material to me for study and report. This second part deals with a large number of these octocorals, belonging to the orders Telestacea, Alcyonacea and Gorgonacea (suborder Scleraxonia). The majority of the specimens reported upon are now in the Rijksmuseum van Natuurlijke Historie, Leiden ; their register numbers are preceded by the abbreviation RMNH. A few specimens collected by Dr. J. H. Stock now form part of the collection of the Zoölogisch...

The Dermaptera of the Caribbean
Provedor de dados: 16
Autores: Brindle, A.
The most complete survey of the Dermaptera of the Caribbean is that of REHN &amp; HEBARD (1917), which mainly dealt with material collected on behalf of the American Museum of Natural History, but additional records from specimens in other American Institutions were included. This publication did not include all previous records and keys to the species were not given, apart from a short key to some names which were regarded as being forms of Carcinophora americana (Beauvois). A number of subsequent papers on the Dermaptera of these islands have been published, these papers either giving records from a single island or recording species from various islands, but no comprehensive survey of the known Dermaptera has been compiled. The islands of the Caribbean...

Over levensvormensystemen
Provedor de dados: 16
Autores: Londo, G.
The author discusses different life and growth form systems. Several of them are very complex, based on many criteria and difficult to apply in floristical and vegetational studies. The so-called dynamic systems are easier to apply and include several different simple systems each based on another criterium. Apart from this the life form systems can also be divided into phenotypical and genotypical systems. In a genotypical system the life forms depend on the genetic properties of the species, e.g. the ability to form rhizomes (e.g. the system of Warming; plants of the same species in different areas belong to the same life form), but in a phenotypical system the life forms depend also on the habitat of the plants (e.g. the system of Raunkiaer; plants of...

The Philippine subspecies of Centropus bengalensis (Gmelin) (Aves, Cuculidae)
Provedor de dados: 16
Autores: Mees, G.F.
The Philippine populations of Centropus bengalensis had been generally included in the widely distributed subspecies C. b. javanensis (Dumont), type locality Java, until Deignan (1955) observed that the population of Palawan is actually referable to this subspecies, but: "that those of other islands are separable by having, in fresh plumage, increased nigrescence of the anterior upper parts, the black or blackish area usually extending to the center of the back". For this subspecies Deignan used the name C. molkenboeri Bonaparte (1850: 108, "ex Philippinis"), which had been listed as a synonym of C. b. javanensis by Shelley (1891), Stresemann (1912) and Hachisuka (1934-1935).

Autores: Heel, W.A. van; Baas, P.
The intention of this serial of review papers covering the various branches of botany is firstly to offer the authors a freedom to express opinions and to speculate as widely as they dare upon future trends, and secondly to offer the classical- and modern-minded readers at least a possibility to dip into each other’s pages so that each may appreciate the other and learn ‘what it is all about’ (Preston, in the preface to Volume I). The present reviewers are engaged in the field of plant morphology and anatomy, to which the last paper of this volume belongs, namely the excellent contribution by P. B. Tomlinson on Monocotyledons (mainly arborescent forms). Tomlinson presents a lively picture of the ‘habit’, vascularization, inflorescence, etc. in these...

Observations on the Bolbitiaceae—IV. Developmental studies on Conocybe with particular reference to the annulate species
Provedor de dados: 16
Autores: Watling, Roy.
The macroscopic characters of the pileus, veil, and stipe of members of Conocybe subgenus and section Pholiotina are related to the microscopic structure and development of the fruit-body. Differences between various authors’ descriptions are explained by results from observations made in the field and in the laboratory. The colour of the pileus and the position of the veil is shown to be more variable in these same fungi than at first supposed. The development of the fruit-body in subgenus Pholiotina is compared with subgenus Conocybe.

Revision of the genus Endospermum Bth. (Euphorbiaceae)

Autores: Schaeffer, J.
The revision was undertaken because the latest monograph by Pax &amp; Hoffmann, dating from 1912, did not provide a satisfactory key, and because since that time a very large amount of new material has been collected and several new species were described. In the present revision 12 species have been recognized, among which 2 are new; 7 names have been reduced to synonymy. One species (E. eglandulosum Pax &amp; Hoffm.) is here for the first time excluded from the genus and from the Euphorbiaceae and was found to be conspecific with Sterculia macrophylla Vent.

Good colour naming and colour coding are essential and also a good colour system. Once such a system has been adopted by an International Botanical Congress it is highly desirable that it be employed universally. To my way of thinking the author of this work is correct in assuming that the system most suitable for this purpose is the Munsell system. I myself used it in describing the colours of Taraxacum achenes. Its three “co-ordinates”, hue, value and chroma, are in agreement with psychological experience and can be translated in physical unities, as is done by the I.S.C.C. (Inter Society Color Counsel) and the N.B.S. (National Bureau of Standards) (America). This is a requisite of normalization.

A Systematic Review of the Hispaniolan Snake Genus Hypsirhynchus
Provedor de dados: 16
Autores: Schwartz, Albert.
One of the least known of the endemic Hispaniolan colubrid snake genera is Hypsirhynchus. The genus was proposed by GUNTHER (1858) for one specimen of a new snake, purportedly from the island of Barbados, to which he gave the name H. ferox. COPE (1862) later described H. scalaris from Hispaniola (type locality – near Jérémie, Departement du Sud, Haïti). This species differed from H. ferox in that H. scalaris lacked a loreal scale; the pattern and coloration were said to be quite different from those stated by GUNTHER to be typical of his species. COPE (1879) established that H. ferox was Hispaniolan rather than Barbadian and considered H. scalaris as distinct from H. ferox. BOULENGER (1894) regarded H. scalaris as identical to H. ferox. However, COCRAN...

Three pollen diagrams from the Peel peatlands, a raised bog area in the southern part of The Netherlands reveal the post-Boreal vegetation history of that region. There are two or three land-occupation phases in the Neolithic and Bronze ages, that show but low values of terrestrial herbs. They are negatively correlated with Ulmus. The Fagus curve starts slightly below the first occupation phase at around 2500 B.C. In the Subatlantic there is an Iron age and a Medieval occupation phase with higher values of terrestrial herbs. Fagus shows two maxima, one at the beginning of our era and another at around 700 A.D. The trend of the pollen curves for bog species is discussed in relation to bog development.

Dr. S. J. van Ooststroom retired
Provedor de dados: 16
Autores: Steenis, C.G.G.J. van.
In January 1971 Dr. Simon Jan van Ooststroom, senior botanist of the Rijksherbarium, retired on reaching the age of 65, having been on the staff since November 1934. Though this event will to a certain extent change, but not interrupt, his work, it is nevertheless worth commemorating, as he has so many contacts at home and abroad, all of whom have profited from his wide knowledge which he shared freely. He was born in Rotterdam in 1906, where he received his primary and part of his secondary education. He completed the latter in Schiedam and entered the University of Utrecht in 1924. He became the assistant of Prof. Dr. A. Pulle in January 1927. By chance he became interested in the genus Evolvulus and this led him to compose an excellent world monograph...

According to the author insufficient proofs exist to consider Stenella plagiodon (Cope, 1866) a junior synonym of Delphinus pernettensis de Blainville, 1817 or of Delphinus pernettyi Desmarest, 1820. To avoid further confusion the International Commission on Zoological Nomenclature is requested to use their plenary powers to suppress for the purposes of the Law of Priority but not for those of the Law of Homonymy the following specific names: a. pernettensis de Blainville, 1817, as published in the combination Delphinus pernettensis; b. pernettyi Desmarest, 1820, as published in the combination Delphinus pernettyi.

Une recherche sur le taux de chlorinité de l’eau interstitielle dans le lit de La Slack
Provedor de dados: 16
Autores: Nooter, K.; Liebregts, F.
The supposition that the Slack, a river in northwestern France discharging directly into the sea, has a significantly higher chlorinity in its bottom sediments than in the overflowing river water, is confirmed. A device to take samples of sediment from the river bottom has been constructed and is described in this publication. To obtain the interstitial water, the sample is simply centrifuged. A peculiar phenomenon, which could not be explained, is that after a regular decrease of the interstitial chlorinities, a considerable increase (to &gt; 1.5 ‰) takes place at a distance of some 2½ kilometres from the mouth. The interstitial chlorinity in the estuarine part of the river proved to be almost constant, regardless of the tidal cycle.

Onvruchtbaarheid, een vruchtbaar terrein van studie
Provedor de dados: 16
Autores: Gadella, T.W.J.
Since our knowledge concerning the time of fruiting of various Angiosperms is very limited, JACOBS (1969, 1970) recently recommended this subject to the attention of amateur-botanists. The present author is of the opinion that also attention should be paid to the study of the absence of ripe fruits. Various causes may be responsible for this aspect: spatial isolation of the sexes in dioecious species (Mercurialis perennis, Stratiotes abides), interspecific hybridization ( (Violahybrids), triploidy (a.o. Stellaria graminea) and predominance of vegetative reproduction (a.o. in Ranunculus ficaria and some strains of Potentilla anserina).

This paper deals with many problems also discussed in van Steenis’s land bridge theory. Aubréville also rejects long distance dispersal and ’reluctantly’ accepts Wegener’s Eocene supercontinent as providing the necessary migration routes. He also postulates that the Eocene equator was far displaced, not making clear whether this is his own idea or somebody else’s. He bases this apparently on the ’tropical’ character of the floras of the European Eocene, of which he is firmly convinced. Aubreville does not realize that Dutoit already in 1937 has rejected Wegener’s Eocene reconstruction as necessitating an ’absurdly late date’ for...

Round about 1930 it was presumed that the imminent closure of the ‘Zuiderzee’ with the resultant change from salt to fresh water might well affect the boundaries of Caltha palustris in the coastal area of the province Friesland. It was thought that inside the dikes Caltha would invade the regions that had previously been too saline for its growth. As many localities as possible were carefully mapped. Now, forty years after the first investigation was carried out the boundary of the area covered by Caltha appears practically unchanged. Very different, on the other hand, is the situation outside the dikes where many new localities have been found on the newly claimed land.

The layered structure of bones of birds as a possible indication of age
Provedor de dados: 16
Autores: Soest, R.W.M. van; Utrecht, W.L. van.
A method of age determination, new in birds, is described. The method has been derived from similar methods commonly used to determine age of fishes, amphibians, reptilians, and mammals. It consists of demonstrating, by preparation of transverse transparent sections, the presence of annual deposits in the periosteal zone (= zone of outer circumferential lamellae) of bone. Evidence is presented that the layered structures in the periosteal zone are indeed annual and thus related with age.

Note on some more tropical labyrinth-seeds
Provedor de dados: 16
Autores: Heel, W.A. van.
There are seeds that, when cut in any plane, show a labyrinth structure (van Heel, 1970). This may be due to folding of the cotyledons (Burseraceae, Dipterocarpaceae), or to the presence of testa tissue within the seed. In the latter case the testa tissue may either be located in the endosperm only (‘ruminated seeds’ in Palmae, Annonaceae, etc.), or the testa tissue may interfere with the cotyledons. It is possible that in some cases the testa at first interferes with the endosperm, and later on, when the embryo has become larger, also interferes with the cotyledons (Corner, 1966, in some Palmae). In the case of testa tissue interfering with the cotyledons, there are probably two possibilities. Firstly the testa may be located between portions of folded...

The author rejects a placing of the species in the genus Ranunculus (as R. ficaria L.) and is in favour of a placing in the genus Ficaria (F. verna Huds.).

Compound leaves and stipules – primitive or derived?
Provedor de dados: 16
Autores: Dawson, J.W.
With considerable justification the woody Ranales are regarded as the most primitive angiosperm group and the features they possess tend to be accepted as primitive for the angiosperms as a whole. The latter view is probably justified in most instances, but it would be unwise to assume uncritically that the woody Ranales are primitive in all respects. For example, because all woody Ranales possess them, simple leaves are regarded as primitive. There is less agreement on the primitiveness or otherwise of stipules because some woody Ranales possess them and others do not. However, if the view that the primitive angiosperm leaf is simple and exstipulate is correct then compound leaves and stipules must be regarded as derived. This may be so, but it should be...

During my study of the Cetoniid genus Thaumastopeus Kraatz, I found Lomaptera cambodiensis Wallace, 1867, listed under Thaumastopeus in Junk's Coleopterorum Catalogus (Schenkling, 1921). A male specimen in the collection of the late F. T. Valck Lucassen (containing material ex coll. O. E. Janson and ex coll. F. J. S. Parry), now present in the Leiden Museum, bears a type-label. It appears to belong to Ischiopsopha Gestro, as suspected previously by Neervoort van de Poll (1886) and surmised by Heller (1895) and Schoch (1898). The generic position of the species is evident from the following characters: shape of the parameres; rather deep lateral sinuation of the elytra just behind the shoulders; sharp transversal ridge somewhat behind the middle of the...

It is a drowned river system, the entrance of which is almost completely blocked by a bar of coral debris reaching to about 2 meters above sea level. The following parts may be easily distinguished: 1) the Boca or “Outer Bay.” 2) the “Entrance,” and 3) the bay proper or “Inner Bay” (see map, Fig. 147). The Boca or “Outer Bay” is about 200 m wide and 6 m or less deep until (about 100 m off-shore) it reaches the outside border of a coastal platform which rapidly falls to several hundred meters. This sandy Boca is not only submitted to a turbid tidal flow of water from the Inner Bay, but, moreover, suffers from the increasing influence...

Notes on Malesian grasses. V. New species and combinations in Pheidochloa, Hyparrhenia, and Leptochloa
Provedor de dados: 16
Autores: Veldkamp, J.F.
Recent collections from New Guinea contained grasses which could only be referred to the genus Pheidochloa S. T. Blake (Proc. Roy. Soc. Queensl. 56, 1945, 20), a monotypic genus so far only known from North Australia and Queensland. The genus seems closely related to Eriachne R. Br., but differs from it by the very unequal glumes, the subterete florets with a deep longitudinal furrow formed by the strongly involuted margins of the lemma, the slender and acute callus, and a cylindric caryopsis.

Carbonate petrology of algal limestones (Lois-Ciguera Formation, Upper Carboniferous, León, Spain)
Provedor de dados: 16
Autores: Meijer, J.J. de.
The Lois-Ciguera Formation is a unit of alternating limestones and terrigenous sediments of Lower to Upper Moscovian age in the Cantabrian Mountains of northern Spain. The proportion of limestones is fairly high, 30 to 50% of the total thickness. In the eastern part of the Lois-Ciguera Synclinorium, the formation consists almost exclusively of limestones. One section (LSW) is selected to serve as a model for the depositional and diagenetic textures of the limestones of the entire formation. More than 80% of the limestones appear to be algal-bound. Description and subdivision of these algal boundstones was possible by a modification of the classification scheme of Dunham (1962). The algal boundstones are classified as algal-bound lime mudstones, algal-bound...

De grote uitbreiding van Puccinellia fasciculata (Torr.) Bickn. in Zeeland als gevolg van inundatie en overstroming
Provedor de dados: 16
Autores: Visser, A. de.
In this paper the distributional pattern of Puccinellia fasciculata in the Netherlands is discussed. It is pointed out that three factors (inundation of considerable portions of the province Zeeland during World War II, extensive flooding of other parts in 1953, and the construction of new dikes) are responsible for the enormous increase in the area of distribution. It is to be expected that with the return to normal conditions the species will largely retreat to more normal distribution.

Neogene vertebrates from the Gargano Peninsula, Italy
Provedor de dados: 16
Autores: Freudenthal, M.
Fissure-fillings in Mesozoic limestones in the Gargano Peninsula yield rich collections of fossil vertebrates, which are characterized by gigantism and aberrant morphology. Their age is considered to be Vallesian or Turolian. The special features of the fauna are probably due to isolation on an island. The vertebrate bearing fissure deposits are covered by a calcarenite which is dated as probably Serravallian on the basis of Foraminifera. This would mean that the continental Turolian may be older than the marine Serravallian, a conclusion which is in contrast with the general idea on the correlation of marine and continental Miocene and Pliocene in Europe.

The uppermost marine fusulinid-bearing strata in northwestern Spain are found in the area of the upper Río Pisuerga in northern Palencia and in the area of the lower Río Cares in Oviedo (Asturia). The youngest fusulinid faunas in the Pisuerga area belong to the Protriticites Zone; they indicate a Lower Kasimovian age. In the area of the lower Río Cares fusulinids belong to the Triticites Zone; they indicate an Upper Kasimovian age. The Protriticites Zone of Spain is defined as the time-span between the first occurrence of Protriticites and the first occurrence of Triticites. One new species – Triticites (Montiparus) fischeri – and one new subspecies – Triticites (Triticites) ohioensis Thompson subsp. benshi – both occurring in the Triticites Zone of the...

Notes on the types of Gnathoclita vorax (Stoll) (Tettigoniidae, Pteropphyllinae)
Provedor de dados: 16
Autores: Jong, C. de.
A remark of one of my colleagues that the ♀ of Gnathoclita vorax (Stoll) is still unknown, urged me to find out whether this was true, as I remembered to have seen both ♂ and ♀ specimens in the collections of the Rijksmuseum van Natuurlijke Historie, Leiden, and of the Naturhistorisches Museum, Vienna. Furthermore, Beier ( 1960: 240) remarked recently of G. vorax that the type is lost ('Typus verschollen"). Fortunately I can state now that the male type of Stoll's Gryllus Acheta vorax is still present, though slightly damaged. In the Leiden collection there are, apart from this type, more specimens of the species, one ♂ and one ♀; both bear a label in the handwriting of W. de Haan, who from 1822 to 1846 was curator of the invertebrate collections of the...

The relation between the genera Cyrtinopsis Scupin, 1896 and Kozlowskiellina Boucot, 1957
Provedor de dados: 16
Autores: Krans, Th.F.
A comparison of some morphological characters of Cyrtinopsis and Kozlowskiellina shows that the micro-ornamentation of Cyrtinopsis is essentially the same as in Kozlowskiellina and consists of growth lamellae, capillae and minor growth lines. The cardinal area of Cyrtinopsis is composed of a central interarea and a lateral palintrope, exactly the same as in Kozlowskiellina. The peculiar pedicle valve interior with the spondylium-like trough of Cyrtinopsis is fully comparable to and homologous with the interior of the pedicle valve of Kozlowskiellina which is also the case with the cardinalia in the brachial valve in both genera. As a conclusion it seems justified to unite both genera in one subfamily which for priority reasons must be named Cyrtinopsidinae.

Cochlearia pyrenaica
Provedor de dados: 16
Autores: Heimans, J.
The few localities of Cochlearia pyrenaica DC. in N.E. Belgium and N.W. Germany, occurring outside the main area in the mountain belt (Pyrenees, Central France, S. Germany, N. Alps, Carpathians), are thought to be relic stations of a more continuous area of distribution in earlier periods, perhaps Late Glacial. This supposition necessitates the restoration of C. pyrenaica to specific rank, even to that of a species group, in contrast to the halophilous Cochlearia species (including C. officinalis s.s.), with mainly a subarctic centre of distribution. Related inland-forms from the British Isles, the East Alps, Poland and Tatra, which are often given (sub-)specific value, may be older “segregates” from the C. pyrenaica group.

Very soon after publication of a description of a new species of Therapon from Western Australia (Mees, 1963), I became aware that I had misidentified one of the species mentioned in the discussion of the affinities of the new species. Originally I intended to write only a short supplementary paper, to rectify the error, but as more material became available, my notes expanded, until it appeared to me that longer postponement of their publication would not be likely to add much of significance. The paper as now published falls far short of a revision; rather, it contains a number of scattered notes on various species, adding, I hope, a little to knowledge of their distribution and affinities, and for that reason I have given it its somewhat vague title....

Eight species of Descolea, four of which—D. pallida, D. majestatica, D. phlebophora, and D. pretiosa —are new, are keyed out and fully described. The area of distribution today stretches from S. America over New Zealand and Australia to India and Japan. According to present knowledge the specific centre of the genus seems to be in New Zealand (three species), but it is presumed that more species occur in the surrounding Pacific area. The generic range of Descolea is discussed and compared with closely related genera belonging to the Cortinariaceae.

Although described one hundred and thirty years ago, Vespertilio brachypterus Temminck remains a relatively poorly known species, such references as there are deriving for the most part from the original description or from specimens referred to V. brachypterus without direct comparison with the holotype. Described from Sumatra, the species was subsequently reported from Java by Fitzinger (1861:390) from the collection made during the exploratory voyage of the Austrian frigate "Novara", a report later repeated by Zelebor (1869: 17). Fitzinger (1870:24) gave a further description, as did Dobson (1876:92, 1878:223), who extended the range of the species to the island of Banka, apparently without reference to a specimen or published record.

He favours Brönnimann's principles of subdividing Pseudorbitoides (1954-1958) on the basis of stages of nepionic reduction, resulting in a distinction of species according 1) to a shift in the distribution of the number of primary chambers in exclusively uniserial populations, and 2) to a...

All cases he illustrated by examples. In certain cases there must have been ’co-evolution’ of parasite and host.

In this paper a report is given on Lycosid spiders of the genus Pardosa, collected in southern France, Spain and Corsica. The animals were taken by hand and therefore the account is a qualitative one. Some other species of Lycosid spiders were also caught. The results will be given elsewhere. As the knowledge about the occurrence of species of Pardosa in the visited areas is rather scarce, it seems worthwhile to publish the data. The results are dealt with as to species, mostly on the basis of Simon (1937) and Tongiorgi (1966a and b). Occasionally data on species which were not collected but occur in great abundance in more northern areas are included (these data mostly are based on Wiebes, 1959).

The Taxonimic association of mus faberi Jentink with Rattus xanthurus (Gray), a species known only from Celebes (Rodentia: Muridae)
Provedor de dados: 16
Autores: Musser, G.G.
Over 60 named forms of Rattus are recorded from Celebes (Laurie &amp; Hill, 1954). Some of these names were first proposed in the i8oo's. The taxa they represent were sometimes based on only one specimen and were often poorly diagnosed. Consequently, the taxonomie status of the names has been unclear. Such names are stumbling blocks to accurate identification and sound classification of the species of Rattus which occur on Celebes. Mus faberi, named and described by F. A. Jentink in 1883, is a classic example. The name represents a taxon based on a single specimen. The original description of that specimen was short and vague. No other specimens have ever been allocated to M. faberi in the mammalogical literature and the taxonomie status of the name has...

Data are given on the taxonomy and ecology of the genus. Some New Caledonian species grow in or descend to the lowland. Details are provided on the distribution within New Guinea.

A special chapter is devoted to a discussion of dispersal which appears to be extremely slow, with the implication that Nothofagus indubitably needs land for its spread, and has needed such for attaining its colossal range, encircling onwards of New Guinea the South Pacific (fossil pollen in Antarctica) to as far as southern South America.

Typification of the genus Macropsidium Bl. (Myrtaceae)
Provedor de dados: 16
Autores: Steenis, C.G.G.J. van.
In revising Myrtaceae Blume correctly concluded in 1849 that Psidium rubrum Lour, from Indo-China could not belong to that neotropical genus. He erected a new genus Macropsidium Bl., to accommodate it, adding at the same time the description of a second new species from the Moluccas. It is desirable to select one of these two syntypes as the lectotype of the genus. I have chosen the one described by Loureiro, which procedure deserves the merit of saving also the generic name Octamyrtus Diels (Bot. Jahrb. 57, 1922, 373) to which I believe Blume’s second species belongs. This leads to the following formal nomenclatural and taxonomic disposition.

In this paper the species referable to the genus Aphistogoniulus Silvestri, 1897, are enumerated and their status is briefly discussed. Mystalides Attems, 1910, is a junior subjective synonym. Two species from Madagascar, A. quadridentatus (Attems, 1910) and A. polleni nov. spec., are described after material in the collection of the Zoological Museum, Amsterdam. The gonopods of a male from the type series of A. hova (De Saussure &amp; Zehntner, 1897) are depicted. The name A. brolemanni nov. spec. is proposed for the material referred to A. hova by Brolemann, 1922.

Autores: Mol, J.-J. van; Tursch, B.; Kempf, M.
Since the publication of a survey of brazilian Conidae (Van Moll et al., 1967) new extensive dredgings effected by one of us (M.K.) along considerable portions of the Brazilian coast have brought a rich material allowing us to add to the previous work and to correct certain opinions therein expressed. Conus testudinarius Hwass, 1792 Conus testudinarius Hwass (see Kohn, 1968, for nomenclature) has been dredged off the mouth of the Amazon (1°10.7'N 46°32.5'W, 100 m deep, calcareous algal gravelly sand and organogenous material. — 2 dead specimens) and off the coast of Ceará (2°13.5'S 40°43.5'W, 53 m deep, calcareous algal sandy gravel. — 1 living juvenile; 2°25.3'S 40°50.5'W, 24 m deep, littoral gravelly sand. — 1 dead juvenile) (see map, fig. 1).

Collocherides astroboae n. gen., n. sp., a siphonostome cyclopoid copepod living in the stomach of basket stars
Provedor de dados: 16
Autores: Stock, Jan H.
The new genus Collocherides, which is created for the reception of C. astroboae n. sp., is closely related to Collocheres. Whereas the species of Collocheres all are, as far as we know, ectoparasites of echinoderms, Collocherides was found endoparasitic in basket stars (Astroboa nuda, A. albatrossi) at Eilat (Israel), in the Dahlak Archipelago (Ethiopia), and in Indonesia.

A revision of the genus Trimenia (Trimeniaceae)
Provedor de dados: 16
Autores: Rodenburg, W.F.
Trimenia was first described by Seemann (1871) and based upon a single specimen from Kandavu, Fiji Islands. This specimen he had referred earlier in a preliminary list of Vitian Plants (1861) to a species of Weinmannia because ‘in habit this singular plant is so very much like some species of Weinmannia (Seemann 1871). He suggested it to belong to the tribe of Ternstroemieae DC. of Theaceae, ‘though the panicles are pluriflorous’. Bentham &amp; Hooker (1880) did not share this view and although the systematic position was not certain as they said, they regarded it to have more affinity to Monimiaceae. Some time elapsed before Perkins &amp; Gilg (1901) and Perkins (1925) placed the taxon definitely in the Monimiaceae as the tribe Trimenieae. Gibbs (1917)...

A new species of characid fish of the genus Nematobrycon from the Rio Calima of Colombia (Pisces, Characoidei, Characidae)
Provedor de dados: 16
Autores: Weitzman, Stanley H.; Fink, William L.
The systematic status of three nominal forms of the Colombian characid genus Nematobrycon is herein treated. All forms are illustrated and their interrelationships discussed. One species, Nematobrycon lacortei is described as new. Nematobrycon palmeri Eigenmann, a species from the northern headwaters of the Rio San Juan is compared with Nematobrycon amphiloxus Eigenmann &amp; Wilson from the adjacent headwaters of the Rio Atrato. It is suggested that N. amphiloxus is probably a subspecies of N. palmeri. N. lacortei from the headwaters of the Rio Calima, a large southern tributary of the Rio San Juan, is considered specifically distinct from N. palmeri at the present time. Judgement on the systematic status of all forms of Nematobrycon must await collection...

In 1960 I made a preliminary analysis of the floristic distribution of the native Phanerogam genera of the Pacific islands, which amounted to 1511 genera in all. The aims of the present work have been to record these more accurately and more critically in detail, especially with regard to native versus introduced, to complete the survey with new records from new explorations made during the interval, and to evaluate new taxonomic literature on Pacific genera. The present list amounts to a total of 1666 genera, as far as known in July 1969, listed in an Appendix. The floristic relationships of the Pacific islands and the surrounding continental areas are established and a hierarchical subdivision of the flora of the Pacific islands based on demarcations in...

Spionidae (Polychaeta) of the Gulf of Mexico and the Caribbean Sea
Provedor de dados: 16
Autores: Foster, Nancy Marie.
Although there have been several collections of polychaetous annelids from the Gulf of Mexico and Caribbean Sea, very few spionids have been included in the published species lists. This is not because they are poorly represented in this area but probably a result of their small size and the fact that they are easily overlooked both in collecting and in sorting of samples. It is also probable that their small size renders them an unpopular group with which to work. Very few spionids were reported from collections of the early large scale collecting cruises. This can be, at least in part, attributed to the fact that they are more common in littoral habitats than in deeper waters. SCHMARDA (1861) reported three species as a result of his world cruise...

C. longa is closely related with Pterygascidia mirabilis Sluiter, 1904, collected from off Timor by the Siboga Expedition, in general appearance of the pedunculate body, situation of the branchial and atrial apertures, structure of the branchial siphon, arrangement of body muscles divided into parts, and in the essential structure of the branchial sac, alimentary canal and gonads. The former, however, seemed to differ distinctly from the latter...

On the identity of Cervus nigricans Brooke, 1877, with remarks upon other deer from the Philippines
Provedor de dados: 16
Autores: Dobroruka, L.J.
A great number of papers deal with the deer of the Philippine Islands but in spite of this fact the taxonomy and the nomenclature are still not clear. The first author who recapitulated all known facts about the Philippine deer was Brooke (1877), who also described a new species, Cervus nigricans. The description is exact, with figures of the habitus and the skull of the indicated holotype (♀), and in my opinion Haltenorth (1963) had no reason to consider C. nigricans a nomen nudum. The validity of the name Cervus nigricans is in full agreement with the International Code of Zoological Nomenclature, adopted by the XVth International Congress of Zoology. Cervus nigricans is rather rare in the collections of museums and, therefore, I am much obliged to Dr....

Enige opmerkingen over de aanpassing van de zeeraket (Cakile maritima Scop.) aan het strand
Provedor de dados: 16
Autores: Veldkamp, J.F.
It has been assumed that the sea-rockets, Cakile Mill., are adapted to life on the beach. It is here suggested that the habit of the plants, their annual cycle, the structure of the fruit and the consequent distribution by the sea cannot be regarded as typical, special adaptations to the sandy beach. In view of the only moderate resistance to salinity, the rather large requirements of nitrogen, fresh water and light the sea-rockets should be regarded as plants of the more nutritive parts of open, sandy habitats with sparse vegetation and sufficient supply of fresh water. These conditions are offered by the beach, whereby the plants can grow there, using capacities more commonly encountered among their prairie and desert relatives, while making use of the...

Low-grade metamorphics of West Irian occur to the east of Geelvink Bay associated with two narrow belts of basic and ultrabasic igneous rocks which represent ophiolitic suites of an eugeosynclinical development beginning in Early Mesozoic time. In both of these belts there are indications of regional metamorphism under high pressure and low temperature conditions. Within the miogeosynclinal, Australian-sided part of the Papuan Geosyncline, on the other hand, metamorphic rocks seem to be associated with intrusives of medium to acidic composition.

De variabiliteit van Veronica hederifolia L. in Nederland
Provedor de dados: 16
Autores: Jongh, S.E. de; Kern, J.H.
The variation and distribution of Veronica hederifolia in the Netherlands is more thoroughly discussed than in the preliminary paper bij DE JONGH (1968). It is shown that only two of the five taxa distinguished by M. Fischer occur, V. hederifolia L. and V. sublobata M. Fischer. The earlier records for V. triloba Opiz refer to V. sublobata. In a rather large number of specimens the combination of morphological characters typical of the two indigenous taxa was not found. Therefore the authors agree with Hartl that Fischer’s microspecies do not deserve specific rank. The correct names on subspecific level appear to be V. hederifolia L. subsp. hederifolia, and V. hederifolia L. subsp. lucorum (Klett &amp; Richt.) Hartl. The distribution of the latter...

Autores: Gras, J.M.J.F.; Maasen, A.M.J.
Fieldwork in French “départements” along the Atlantic coast from southern Brittany to the northern part of the Aquitaine Basin, revealed 324 inland and brackish localities with gammarids. Particularly interesting are 21 new stations of Echinogammarus spinulicornis (which was known from 3 places only, all more to the south). This species prefers the mid-course of rivers, especially habitats without vegetation. Gammarus zaddachi is recorded for the first time south of the Loire.

Ecology of the medusa Cassiopea xamanchana in Curaçao
Provedor de dados: 16
Autores: Kristensen, Ingvar; Ypma, Liesje.
1. Cassiopea xamachana is unable to tolerate any wave action, turbulence or currents. 2. Although the species is found only in shallow water where the light intensity is high, it could not be demonstrated that light intensity is an important factor. 3. Normal temperature fluctuations — at least in the Antilles — are of no significance as the range that Cassiopea under laboratory conditions proved to be able to withstand is wider than the fluctuations occurring in their natural environment. On the other hand, after heavy rainfall when the pools are covered with fresh water the bottom water temperature may rise to deleterious levels. 4. The salinity range in the habitat of Cassiopea is from about 33‰ to 54‰. When the regeneration rate is used as a parameter...

Stusies in the Family Thelypteridaceae. III. A new system of genera in the Old World
Provedor de dados: 16
Autores: Holttum, R.E.
The new scheme of classification presented in this paper is based on the examination of all species in the family Thelypteridaceae which I have been able to trace in the Old World. I have gradually compiled a list of about 700 names (basionyms) and have examined type or other authentic material of all but a small proportion; and in the course of study of specimens in many herbaria I have noted about another 50 species which appear to be undescribed. I have attempted to re-describe all the previously-named species, noting characters not mentioned in existing descriptions, especially the detailed distribution of hairs and glands, including those on the body and stalk of sporangia, and characters of spores. It is probable that there remain some published...

On March 1st, 1971, Dr. Hermann Otto Sleumer, senior staff member of the Rijksherbarium, retired on reaching the age of 65 years. I have expressly omitted to say ‘from active service’, because his work has gone on uninterruptedly and he even had objections against spending one afternoon, on Febr. 26th, to celebrate this occasion with speeches and a reception in his honour. Also Mrs. Sleumer found it quite unnecessary and did not anticipate it with pleasure, but afterwards both told us that they had enjoyed it immensely. The story of the life of a scientist is to me always fascinating if it provides, apart from the plain facts of education, career, and bibliography, an insight also into the motives of his personality, the opportunities life offered to him,...

Provedor de dados: 16
Autores: Voo, E.E. van der.
HEUKELS-VAN OOSTSTROOM (1962) mentions that Ranunculus aquatilis subsp. peltatus occurs in the pleistocene part of the Netherlands. In 1966 the species was found some tens of kilometers west of the western border of the area, in the centre of the polderland near Bodegraven in a small natural stream of young-holocene origin (a geographical phenomenon). The habitat of the species is a small winding ditch containing shallow water with only periodical weak movement. The vegetation is strongly influenced by anthropozoogene factors. The species is not accompanied by the characteristic species of Callitricho-Batrachion except Hottonia palustris. In 1970 the species occurred in a few number of individuals as a probable consequence of an excessive development of...

Notes on Malesian grasses. IV. A synopsis of Centotheca and reduction of Ramosia
Provedor de dados: 16
Autores: Monod de Froideville, Ch.
In 1916 Merrill described a new monotypic genus of Gramineae, Ramosia, from the Philippines, recording one species, R. philippinensis, based on one single collection by Ramos, BS 23607, from Lake Pulog, Sorsogon Prov., Luzon, 27-8-1915, where the plant grew along the border of the lake, either in wet swampy places or in shallow water. Except for the type no other specimens have ever been mentioned, nor encountered during this study. Merrill could not place his new genus with certainty, comparing it with Panicum nodosum Kunth and Glyceria. In 1923 he placed it near Festuca and Bromus. The genus was not taken up by C. E. Hubbard (1934), while Pilger (1954) placed it provisionally in Festuceae—Melicinae. The late Dr. Jansen saw an isotype in Kew and noted in...

The occurrence and position of the ”connecting sac” in the nasal tract complex of small odontocetes (Mammalia, Cetacea)
Provedor de dados: 16
Autores: Schenkkan, E.J.
The aspects of the “connecting sac” are studied in Lagenorhynchus albirostris, Lagenorhynchus obliquidens, Lagenorhynchus acutus, Tursiops truncatus, Delphinus delphis, Phocoena phocoena, Sotalia guianensis, Stenella coeruleoalba and Stenella frontalis. Comparing the development of the connecting sac in the various species it is found that there are great variations. These variations are also found in the various individuals of the same species. For this reason the importance of this structure in soundproduction is open to doubt. The development of the connecting sac seems to be related to the development of the posterior part of the naso-frontal sac in such a way that, when a large and well developed posterior part of the naso-frontal sac is present, the...

Some rain and savanna forests of western Suriname (Corantijn R., Winana Creek; Upper Marataka R.; Upper Nickerie R;) were studied and their composition was compared with that of forests of other parts of Suriname and Guyana. The savanna forests of western Suriname proved to be much related to Guyanan ( Walabaand Dakama-) savanna forests as described by Davis &amp; Richards (1934) and Fanshawe (1952). On the other hand, there was less relationship as regards rain forests of western Suriname when compared with ones of Guyana and other parts of Suriname, except for the Demerara greenheart forest of the Upper Marataka R., which was closely related to the Demerara greenheart forests of Guyana as described by Davis &amp; Richards (1934).

Enkele gegevens over de standplaats van Hypericum canadense L
Provedor de dados: 16
Autores: Westhoff, V.
Hypericum canadense L. is an amphi-atlantic species, known in Europe from two localities only: Lough Mask in Ireland and northeastern Twente in the Netherlands. The habitat of the species on the western shore of Lough Mask is described with the help of four sample plots, and this site is compared with the habitat at Farnham, Quebec, Canada. The Irish habitat is a complicated and rare ecosystem. On the basis of a water-logged sandy soil which is superficially inundated during a major part of the year and moreover poor in lime, mesotrophic and extensively grazed, it presents four gradients: (1) a ‘macro-gradient’ from the calcareous soils east of Lough Mask to the silurian slates at its western shore; (2) a ‘meso-gradient’ starting from alternating low sandy...

In situ Gymnosperm pollen from the Middle Jurassic of Yorkshire
Provedor de dados: 16
Autores: Konijnenburg-van Cittert, Johanna H.A. van.
In this paper the morphology of pollen grains yielded by male Gymnosperm fructifications from the Jurassic flora of Yorkshire is studied and discussed. Several new male fructifications were found and described: Hastystrobus gen. nov. was erected for male cones yielding the Eucommiidites type of pollen grains. This genus is monotypic and the type species Hastystrobus muirii yielded pollen grains that agree with Eucommiidites troedssonii. Hastystrobus muirii very probably has Cycadalean affinities, because the whole abaxial surface of the microsporophylls is covered with sporangia. For the first time the male fructification of Ginkgo huttoni (Heer) Sternberg is described. It resembles in general the male fructification of the recent Ginkgo biloba L., and the...

Bonefish-otoliths from the Anversian (Middle Miocene) of Antwerp
Provedor de dados: 16
Autores: Gaemers, P.A.M.
31 species are listed from the Anversian in the neighbourhood of Antwerp (Belgium). Nine were previously known and one recorded species could not be found again. The relative abundances of the species are discussed, especially with reference to Trisopterus friedbergi and small species. The faunas from the ‘Zanden van Antwerpen’ (Sands of Antwerp) and the ‘Zanden van Edegem’ (Sands of Edegem), which make up the Anversian, are compared: the latter is older and the fauna preferred an environment close to the coast or shallow marine; the former, younger formation was formed in slightly deeper water further from the coast. The numerous otoliths of deep-sea fishes in the Sands of Antwerp must be allochthonous, although how these otoliths came to be there is...

A brief biography of Tiberius Lambergen (1717—1763) is given. Lambergen was appointed professor of botany (and medicine) at Franeker in 1749, and of botany, medicine and chemistry at the University of Groningen in 1753. Although there is no definite proof, it is probably correct to assume that Lambergen, apart from making many improvements, introduced the Linnean system and nomenclature into the Groningen botanic garden. Lambergen was a colleague and contemporary of David de Gorier, professor of botany at Harderwijk, after whom this journal has been named.

Nieuwe vindplaatsen in Friesland van Carex aquatilis Wahlenb., 2
Provedor de dados: 16
Autores: Ploeg, D.T.E. van der; Rudolphy, F.
New localities of Carex aquatilis in the province Friesland are reported. The species grows practically always in company of C. acuta, much more rarely together with C. vesicaria. Although C. aquatilis resembles C. acuta so closely as to cause frequent confusion, the authors through thorough acquaintance learned to distinguish both species already from some distance. Carex aquatilis differs from C. acuta in its colour, which is a somewhat glossy yellow-green, produced by the underside of the leaves, whilst the inflorescence is typically paniculate reminding one of the situation in Cladium mariscus; in C. acuta bracts and spikes are gracefully curved to one side, hence the synonymous epithet C. gracilis.

In April 1969 I paid a visit to Ceylon for a week, allowing me to study for the first time the collections of the Department of Agriculture, Peradeniya (PDA), including Thwaites type specimens. My stay was made possible through the Smithsonian Flora of Ceylon Project. The study of Thwaites’ type material revealed some new facts affecting the synonymy of Ochna jabotapita L. and O. obtusata DC. It had previously come to my attention that materials distributed as O. moonii Thw. under number C.P. 1224 belonged to either O. obtusata (BM, BO) or O. lanceolata Spreng. (K, P) (see also the note on page 26 of my revision). I subsequently found that all three species of Ochna in Ceylon were represented on the sheet in PDA, obviously bearing Thwaites’ holotype.

A pesar de que la presencia de la tortuga canal Dermochelys coriacea en las playas al este de Santa Marta era conocida por los mismos tortugeros, esta publicación preliminar es el primer informe científico sobre la anidación de esta especie en Colombia. En el año de 1970 observaron los inspectores del "INDERENA" y el autor, en la playa comprendida entre los ríos Don Diego y Buritaca, 7 hembras desovando, más 4 nidos y 7 nacimientos. Se describe el comportamiento de anidación, comparándolo con el de otras tortugas marinas. Dos de los animales observados fueron marcados, uno de ellos re-encontrando por los guardias del “Inderena”, desovando nuevamente después de 20 días.

Los procesos de mineralización del carbono y del nitrógeno fueron estudiados en un terraplén costero, en una hondonada y en un terraplén interno de la Isla de Salamanca en el Mar Caribe. El pH, y el contenido de cloruros y carbono, lo mismo que la capacidad hídrica fueron los más altos en el suelo húmedo de la hondonada; seguido del terraplén interno; el terraplén costero tuvo la capacidad hídrica más deficiente, y el más bajo contenido en cloruros y en nitrógeno. En la hondonada se encontró el más alto contenido en bacterias; las mayores poblaciones de hongos se encontraron en el terraplén interno. La actividad del suelo (producción de CO2 y amonificación) dependió del contenido de nitrógeno y cloruros de los lugares investigados.

A simple volumeter for small invertebrates
Provedor de dados: 27
Autores: Persoone, G.
The displacement technique for measuring the volume of plankton catches is well established, and a number of papers have been published describing suitable apparatus for this purpose including those by Frolander (1957), and Yentsch &amp; Hebard (1957). Gnanamuthu (1952) reviews several papers dealing with equipment for measuring the volume of small aquatic animals and discusses his own volumeter. The apparatus here described employs a water column and is, therefore, more convenient to handle than previous designs which used a mercury column. It is inexpensive and simple to construct, and will measure to 0.01 or even 0.005 ccm. We have found it most useful in quickly measuring the volume of polychaetes or oligochaetes, small bivalves, small crustaceans, etc.

Determination of nitrate ion in marine biotopes with high nitrate content by ultraviolet spectrophotometry
Provedor de dados: 27
Autores: Mertens, J.; Massart, D.L.
A simple and rapid method for the determination of nitrate in seawater of high nitrate content (&gt;1 ppm) is proposed. The absorption of the nitrate ion is measured at 210 and 220 mµ. The sample is treated with a measured quantity of hydrochloric acid to eliminate the carbonate and bicarbonate interferences and measured against a nitrate free blank prepared by reduction of the nitrate to ammonia with Raney nickel. The addition of HCl permits also storage of the sample without special precautions and the use of the blank eliminates the most serious of the interferences (bromide) expected in seawater. The interference of organic matter limits however the applicability of the method to concentrations higher than 1 ppm.

The oyster culture, flourishing along the Belgian coast at the beginning of the century, perished entirely in the course of two World Wars. In 1956, it was taken on again intensively in the Scour Basin of Ostend. If we consider the obtained results with the affination of Flat and Portuguese oyster, this 86 ha closed basin, is of an exceptional productivity. Essays on the understanding of the origin of calcified oysters, done from 1960 until 1966, turned out to be very promising and an integral oyster culture from the larvae up to the adult oyster could be observed. In any case the last few years, eventhough compared to before a normal emission of larvae of &lt;i&gt;Ostrea edulis&lt;/i&gt;, there has not been a fixation of the origin. Regular samples of...

Inleidende oecologische studie van klei- en turfbanken in de getijdenzone te Raversijde (België)
Provedor de dados: 27
Autores: Jocqué, R.; Van Damme, D.
The beach of Raversijde shows substrata which are very rich in comparison to the rest of natural substrata along the Belgian coast, consisting exclusively of sandy beaches. At this moment however it is threatened by silting up due to construction of breakwaters. From June to December 1970 samples were taken at several places of the beach. The investigation was focused on the peatbanks situated around mean tide level and the claybanks near low tide level. The foulding of those substrata was compared to that of wooden wreck situated near mean tide level . We found that the foulding on the vertical slopes of peatholes was characterised by as striking periodicity. This is due to the fact that only a few organisms are able to settle down immediately on peat....

The differentiation of blood proteins during ontogeny in &lt;i&gt;Sepia officinalis&lt;/i&gt; L.
Provedor de dados: 27
Autores: Decleir, W.; Lemaire, J.; Richard, A.
1. Blood from embryos, young animals and adult &lt;i&gt;Sepia officinalis&lt;/i&gt; L. has been analysed by an ultramicroelectrophoretic technique.2. During the differentiation of a very small embryo into a 2-month-old animal, we have found eleven different protein fractions. 3. All these proteins have been identified as hemocyanin by histochemical tests. 4. The possible origin of the embryonic, young and adult hemocyanins is discussed.

Ecology of fouling on submerged surfaces in a polluted harbour
Provedor de dados: 27
Autores: Persoone, G.
Growth on submerged substrates (fouling or "Aufwuchs") has already been the object of numerous studies especially with regard to its economic implications.  The scarcity of investigations on the influence of pollution on development and evolution of the fouling-biocoenosis is surprising. As far as we know the smaller fauna and flora in this particular situation have never been studied quantitatively.  Therefore, in 1963, 1964 and 1965, a number of experiments were carried out in the harbour of Ostend (Belgium) on submerged substrates of different nature, in order to study the following less known aspects of fouling: a) the successive stages in the development of fouling, from bacteria to macro-organisms.  b) the influence of several factors on its...

Sur un matériel ichthyologique des "Midra (and Saila) Shales" du Qatar (Golfe Persique)
Provedor de dados: 27
Autores: Casier, E.
The study of a collection of fish remains from the Eocene of Qatar (peninsula of the western coast in the Persian Gulf) reveals that the Midra (and Saila) Shales of that region belong to the Lutetian and not to the lower Eocene. This fish fauna proves to be very similar to the corresponding fauna of the Tethys of that age and shows more particularly an affinity with the one of the Lutetian of Egypt, as much from the systematic point of view as from the one of the climatic (tropical) and depositional (neritic) conditions.

Contribution à la connaissance du phytoplankton de l'Atlantique nord-est et de la Mer du Nord
Provedor de dados: 27
Autores: Louis, A.; Clarysse, R.
This study shows that the principal ecological factors influencing the studied area are light, determined by very unequal day lengths, the wind, provoking a fairly homogenically mixed layer of microscopic organisms, and water depth, which in correlation with the proximity of the coast line determined the nutrient salinity concentration. The floral study allowed the determination of algal concentration in the different zones during different periods of the year, and also the quantitative and qualitative photosynthetic activity fluctuations of several florules. The study also resulted in a zonal and chronological delimitation of a large number of species of the studied area. The degressive lists, based on the mean algal frequency, showed the...

Turbellaria from Somalia: I. Kalyptorhynchia (part 1)
Provedor de dados: 27
Autores: Schockaert, E.R.
In this first contribution on Somalian marine microturbellarians, a detailed description of three new species belonging to the family Polycystididae is given. Very few data are available on representatives of this family from the Indo-Pacific area. The available data are from the American Pacific coasts (Marcus, 1954a; Schockaert &amp; Karling, 1970) and from the Antarctic (Karling, 1952). Karling (1952) described the first Polycystidid, &lt;i&gt;Koinocystella inermis&lt;/i&gt;, with a copulatory organ of the conjuncta type; Schockaert &amp; Karling (1970) proposed a new subfamily Duplacrorhynchinae to contain the three new species they described. The Somalian samples collected by the author contained three new species with a remarkable anatomy that...

THE COST-PRICE SQUEEZE ON AUSTRALIAN FARM INCOME
Provedor de dados: 31
Autores: Glau,   T.E.
Relative price movements for major agricultural commodity groups are reviewed. Estimates of the movement in real farm income per farmer are presented for Australian agriculture over the period 1949 to 1969, and for the sheep industry for the period 1953 to 1967. Increased productivity has offset the adverse price movements experienced by farmers over the period examined. The effect of the cost-price squeeze on farm investment and adjustment is discussed. The continuing cost-price squeeze has not prevented sustained investment by farmers.

Adjustments to Resources Formerly Used for Dairying on the Far North Coast of N.S.W.
Provedor de dados: 31
Autores: Christiansen,   T.J.
This paper examines the present use of resources which have left the dairy industry on the Far North Coast of New South Wales in recent years. The number of suppliers to dairy factories in the Richmond-Tweed area has declined by approximately 9 per cent per annum over the last four years. This decline is not simply a result of the economic position of the small dairy farmer; many other factors are also involved. Beef production is the dominant land use replacing dairying, and there is an associated decline in the intensity of labour use on farms. Many former dairy farmers have accepted a lower income as a result of leaving the industry. Non-farm employment has played a part in most increases in income which have occurred.

Spatial Diversification by Beef Producers in the Clarence Region
Provedor de dados: 31
Autores: Trebeck,   David B.
A simulation model was constructed to ascertain the extent of benefits from spatial diversification when an intensive form of use is assumed for the additional (alluvial) land. Although expected profit increased and coefficient of variation decreased, the return to additional capital was only 2.7 per cent. Spatial diversification successfully overcomes winter-spring feed uncertainties, but appears economically doubtful under present assumptions. Some alternatives and modifications are suggested which, although untested, might improve the economics of diversification.

THE INCIDENCE AND EFFECTS OF DEATH DUTIES ON WOOL-GROWING PROPERTIES IN SOUTH AUSTRALIA
Provedor de dados: 31
Autores: Thomson,   Norm J.
Death duties are allegedly a tax designed to redistribute accumulations of wealth. Therefore, to the extent that they are successful, one might expect death duties to inhibit the trend for wool-growing properties to become more capital-intensive. This aspect of death duties appears to be in complete contrast to other rural policy objectives designed to encourage on-farm investment. However, while a survey of 58 death duty-affected properties established that death duties do reduce the rate of capital accumulation, the impact appears to be less severe on the wealthy than the less-wealthy families.

PUBLIC INVESTMENT ANALYSIS AND ITS RELEVANCE TO DEVELOPMENT PLANNING IN THE LDC'S
Provedor de dados: 31
Autores: Johnson,   Joseph S.
Over the past two decades public investment analysis has increased considerably, both in theory and practice.  This can be observed from the vast amount of literature which is now available in this field compared to the interwar period, and the use being made of benefit cost analysis and other related investment analysis in decision making for the allocation of public resources.  Public investment analysis in the form of benefit cost analysis was first explored by a Frenchman, Jules Dupuit, towards the middle of the 19th century.  The first systematic attempt to apply benefit cost analysis to public economic decisions seemed to have occurred in the United States, however.  This occurred in the field of water resource development.

The Economics of Commodity Futures Markets: A Survey
Provedor de dados: 31
Autores: Gray,   Roger W.; Rutledge,   David J.S.
This article reviews some of the literature pertaining to futures markets. After briefly considering how the evolution of the institution of futures trading has required changing interpretations, we devote a longer section to the interplay between theory and evidence concerning intertemporal price relationships. While disputed and inconclusive interpretations persist, Working's theory of the price of storage and his revision of hedging doctrine are clear landmarks of progress in understanding these price relationships. We deal separately with hedging theory; then with the relation between futures and price variability; and finally with the stochastic attributes of futures prices.

A method is outlined to test the stability of a plant location solution to changes in regional production. Supplies are generated within a probabilistic framework and used as input data for the usual otherwise static model. This approach also yields additional information on the probability of actual plant throughput exceeding designed throughput. Such types of information further assist policy decisions.

AGGREGATION OF MICRO-FUNCTIONS TO OBTAIN A WHOLE-FARM PRODUCTION FUNCTION
Provedor de dados: 31
Autores: Johnson,   R.W.M.
In this paper, a re-assessment of the aggregation problem in farm production functions is attempted. Aggregation starts from measurable farm management entities such as the milking cow, breeding ewe etc., and appropriate whole farm production functions are derived that are consistent with these biological units of farming, or as they will be called, the micro-functions of agriculture. The aggregate function, as derived, is based on the geometric means of micro outputs and inputs and could appropriately be said to 'represent' all the micro-functions. It is thus called, later in the paper, the representative production function for the farm firm.

RISK, UTILITY AND STOCKING RATE
Provedor de dados: 31
Autores: McArthur,   I.D.; Dillon,   John L.
A simple utility-based model of risky wool production is presented. Evaluation of the model indicates the effect on optimal stocking rate of changes in the degree of risk aversion, farm area, variable cost, fixed cost, wool cut, wool price, variance of wool price, climatic variability and tax rate. It is shown that the utility hypothesis implies a lower optimal stocking rate than does expected profit maximization and hence implies a discrepancy between private and public optimal resource use which it is suggested, might be mitigated by a progressive bounty on wool production.

This paper examines the economic feasibility of Lostock Dam on the Paterson River, N.S.W. under a number of assumptions as to the resulting quantity and type of additional output. It is shown that the dam has a benefit-cost ratio greater than one only when the additional water is fully utilized and the discount rate is 5 per cent. However farmer estimates indicate that only a proportion of the extra water will be used, in which case the benefit-cost ratio is less than 0.1.

Consumer Demand for Food Commodities in the United States with Projections for 1980
Provedor de dados: 31
Autores: George,   P.S.; King,   Gordon A.
This study analyzes the demand for food commodities in the United States in the postwar period using both time-series and cross-section data.  Income-consumption relationships are based on data from 1955 and 1965 USDA household food consumption surveys. The analysis co cross section data emphasized: (1) effects of grouping observations, (2) choice between expenditures are quantities as the dependent variable, (3) effects of household size on income-consumption relationships, (4) shifts in the regression coefficients (intercepts and income elasticities) between 1955 and 1965, and (5) regional variations in the income-consumption relationships. A demand interrelationship matrix was developed for 49 commodities or commodity groups at the retail level....

SOME OBSERVATIONS ON AGRICULTURAL MARKETING PROBLEMS IN VENEZUELA
Provedor de dados: 31
Autores: Brea,   Luis E.
The role of the agricultural sector in the process of economic development has been a controversial issue in the postwar development literature, as well as in the policy field.  In recent years there seems to be greater acceptance of more balanced approaches to development which recognize the inter-relations of the various factors, such as agriculture and industry.  The argument for balanced growth strategies stresses the mutual interdependence of the agricultural and industrial sectors.  Increases in agricultural output frequently require the widespread adoption of modern technologies.  This involves the purchase and use of industrial products, such as fertilizers, pesticides, tools, and machines.  Unless these industrial products are available at...

PROBLEMS OF COORDINATION AND TRAINING IN WEST PAKISTAN AGRICULTURAL EXTENSION SERVICES
Provedor de dados: 31
Autores: Ahmad,   Saeed.
In West Pakistan the agriculture sector achieved an annual growth rate of four percent during the Second Plan period (1960-65) mainly through increased supply of irrigation water and fertilizer use.  The extension service, though quantitatively improved, did not play a major role in this development.  The main objective of this study was to analyze the problems being faced by the extension service and to explore the type of extension service suitable for a traditional phase in the development of agriculture.

An outline and appraisal is given of Bernoullian decision theory with a view to its potential use in agricultural contexts, both on and off the farm. Despite the existence of a variety of difficulties and unresolved problems, it is argued that Bernoulli's Principle--because of its recognition of the personal nature of decision making in terms of beliefs and preferences--represents the best possible approach to risky choice in agriculture.

APPLICATION OF SAMPLING SURVEY IN ESTIMATING AGRICULTURAL STATISTICS OF THAILAND
Provedor de dados: 31
Autores: Buasri,   Prajiad.
Thailand is an essentially agricultural country.  Agriculture provides direct employment to 81 percent of the nation's population.  Approximately one third of the Gross Domestic Product originates in the agricultural sector, including agricultural crops, livestock, fisheries, and forestry.  Substantially more income is earned in the marketing and processing of agricultural commodities.  The major exports of Thailand continue to be primary agricultural products such as rice, rubber, teak, corn, kenaf, cassava, oil seeds, and other upland crops.  These account for 90 percent of total foreign exchange earnings.  Since Thailand has a prosperous agrarian economy, and agriculture continues to be the main economic activity despite the growing importance of other...

THE NATURE OF PRICE MOVEMENTS DURING SINGLE SALES FOR THREE INDIVIDUAL WOOL TYPES SOLD IN SYDNEY
Provedor de dados: 31
Autores: Payne,   R.A.; Whan,   R.B.
Price series for three wool types sold in Sydney are tested for the presence of serial correlation using the von Neuman ratio. The results indicate that it is unusual to find significant serial correlation between prices during a single sale. These results have implications for the use of various statistical techniques in wool marketing research and for buying tactics in the market generally.

The Sensitivity of Interfarm Comparisons to Inaccuracies of Measurement and Valuation
Provedor de dados: 31
Autores: Mauldon,   Roger G.; Schapper,   Henry P.
This paper discusses accuracy of recording, allocating and valuing in the context of comparisons between farms of efficiency ratios and gross margins. Some experiments were conducted to investigate the effects on rank orderings of livestock gross margins of (i) different allocations of failures to reconcile between recorded sources and recorded uses of livestock, and (ii) of random changes in valuations of livestock. The outcome of the experiments suggests that inaccuracies which occur in farm recording, allocating and valuing can lead to wrong classifications of farms into groups for comparative purposes.

THE ELASTICITY OF DEMAND FOR THE EXPORTS OF A SINGLE COUNTRY - A RECONSIDERATION
Provedor de dados: 31
Autores: Taplin,   J.H.E.
One country's exports of a particular commodity are usually imperfect substitutes for similar exports from other countries. Consequently, the price elasticity of export demand involves unknown cross elasticities between sub-groups of the commodity. However, there are constraints on the relative magnitudes of all the sub-group elasticities. These make it possible to assess the degree to which the whole commodity elasticity divided by the market share is an over-estimate of the export elasticity.

Suggested Methods for Estimating Adult Equivalence Scales
Provedor de dados: 31
Autores: McShane,   R.W.
When trying to obtain an estimate of the demand function of households for certain food items, it is often convenient to express the demographic structure (size, age and sex composition) of individual households in terms of so many consumer (e.g. an adult male) equivalents. In many studies such conversions have been made by using adult equivalence scales derived from nutrionists estimates of the consumption requirements of human beings at various ages. However these scales, by their nature, are based on estimates of how much a person of a given age and sex should consume, rather than on how much the same person actually does consume in real life. In an endeavour to overcome this difficulty a method is suggested in this article whereby a scale can be...

WORLD NEEDS FOR FOOD AND FIBER: SOME ECONOMIC ASPECTS OF SCIENCE REQUIREMENTS, RESOURCE DEVELOPMENT, AND THE ENVIRONMENT
Provedor de dados: 31
Autores: Abel,   Martin E.
This paper addresses itself to three aspects of world food and fiber needs and the protection of the ecosystem. The first is to distinguish between food and fiber needs of the world on the one hand, and the production of food and fiber in developing countries as part of a long-term process of economic development on the other. The second area of attention is the role of science and technology in the process of agricultural modernization and development. Finally, we will look at a class of problems dealing with socially costly externalities associated with agricultural development and the use of new technologies.

AN OCTOBER PREDICTION OF THE DETROIT NOVEMBER PRICE FOR EGGS AT THE WHOLESALE LEVEL
Provedor de dados: 31
Autores: Lee,   Moon K.
The primary objective of this study is to formulate a multiple regression equation for predicting the November average price of Grade A, white, large eggs delivered in Detroit, Michigan.  To accomplish the objective, several equations will be tried.  The equation with the highest predicting power will be chosen to predict November price in 1970 as of October of that year.  October was chosen on the basis that October price difference between medium and large size affected the November price considerable.  Therefore, the factor just could not be dropped.  The secondary objective in the study is to examine demand elasticities for eggs.  Egg producers and policy makers may have the base in making decisions if egg marketing order is ineffective in the future.

In a recent reappraisal of evidence adduced for allocative efficiency in traditional agriculture, Dillon and Anderson employed a method based on a combination of traditional economic aspects and statistical aspects of estimated production functions. However, their reappraisal involved using marginal rather than the (appropriate) joint distributions of the regression coefficients. This paper investigates the error associated with using the inappropriate marginal distribution in a reassessment of allocative efficiency in wool growing in the Australian pastoral zone.

The Effect of Declining Wool Prices, Wheat Quotas and Debt Reconstruction on the Financial Viability of Australian Farmers
Provedor de dados: 31
Autores: Davidson,   Bruce Robinson.
An examination of the decline in net farm income between 1966-67 and 1969-70 indicates that in the three major zones the following size groups will be non-viable (l) In the High Rainfall Zone, farms with less than 2,000 and more than 10,000 sheep, comprising 85 per cent of farms in the Zone. (2) In the Wheat Sheep Zone, farms with less than 1,000 sheep, comprising 56 per cent of farms. (3) In the Pastoral Zone, farms with less than 20,000 sheep, comprising 98 per cent of farms. This situation could be alleviated to some extent by extending the period of debt repayment from the present average period of 7 years to a period of 20 to 30 years.

AGRICULTURE IN THE DEVELOPMENT OF PAPUA AND NEW GUINEA
Provedor de dados: 31
Autores: Parker,   M.L.
Primary production including subsistence production, accounts for about 60 per cent of the national income of Papua and New Guinea. The bulk of the indigenous people are subsistence farmers, or have contact with the cash economy through agriculture, and the agricultural industries provide virtually the sole source of export earnings. The position is nevertheless changing rapidly.

AN ANALYSIS OF INSTITUTIONAL MODIFICATIONS FOR EFFECTIVE FARMER CREDIT IN CEYLON
Provedor de dados: 31
Autores: Samuel,   S.N.
A primary objective of the Agricultural Credit Scheme of 1967 was to accelerate the pace of economic development.  Economic development was to be promoted by the credit scheme's expected contribution towards increasing agricultural output and incomes.  Agriculture occupies a dominant position in the Ceylon economy, with the rural sector containing over 50 percent of the population.  An increase in agricultural output would have an overall effect on per capita incomes and national welfare.  The dominance of the agricultural sector makes the interplay between development means and development objective important in that sector.  Hence, there appears to be wide scope for raising gross national product through agricultural development.   Increasing...

A STUDY OF AGRICULTURAL PRODUCTIVITY IN CHILALO DISTRICT OF ETHIOPIA AND THE THIRD FIVE YEAR DEVELOPMENT PLAN
Provedor de dados: 31
Autores: Solomon,   Seyoum.
Agriculture is the largest sector in Ethiopia's economy, it accounts for about two-thirds of the gross domestic product, employs about nine-tenths of the labor force and provides nearly all the export earnings.  The smallholder farms, on which 90 percent of the nation's population depends for its food supply, have been unable to raise their productivity due to many persisting problems.  Unlike many developing Asian countries, Ethiopia does not face shortages in cultivable land.  During the past twenty years, many strategies have been developed to modernize Ethiopia's agriculture and bring her economy up the ladder of development.  Ethiopia is now in the third year of the Third Five-Year Development Plan.  However, the pace of development has not...

Time dependency of hydrogen - ion concentration and electric conductivity measurements in river water samples of Central Amazonia()
Provedor de dados: 36
Autores: Brinkmann,W.L.F.; Santos,A. dos.
Abstract The hypothesis was tested, whether hydrogen — ion concentration and electric conductivity in river water samples of the Tertiary region of central Amazonia were subject to changes in time and due to nature of storage. Over a period of about two months only changes in pH and conductivity of Rio Negro water samples were found to be significant. The total deviation of both parameters in rain forest stream samples was considered negligible for at least a period of 30 days, independant of the nature of storage (laboratory or icebox). The latter results may be generalized more or less unconditionally for the entire Tertiary formations of Amazonia.

Sinopse A continuidade da produção de óleo essencial de pau-rosa na Amazônia, não está assegurada, em virtude das dificuldades resultantes da propagação e do crescimento lento da Aniba duckei Kosterm. Com o propósito de resolver o problema se estabeleceram duas linhas de pesquisas: 1. a análise (incluindo variações periódicas da composição) do óleo das fôlhas de pau-rosa (rendimento de 2,0-2,5%) obtido da Aniba duckei Kosterm. (Lauraceae). 2. um estudo das plantas comuns na Amazônia, quanto a seu teor de linalol, que levou a descoberta do óleo das fôlhas (rendimento 0,8%) obtido de Croton cajuçara Benth. (Euphorbiaceae), contendo mais de 66% de linalol.

Summary The present paper is the continuation of a catalogue of foliar venation of plants of the Amazonian flora, dealing with a source of data for ecology and paleobotany, and a set of auxiliary characters in taxonomy. Results indicate that certain differences in the arrangement of vein network, in the number of translucid glands per mm2, and in the gland position along leaflet margin allow the studied species to exclude from other four species belonging to the camptodroma group. A key for comparing specific discrimination among the species of genus Fagara belonging to the camptodroma group of Ettingshausen's vein patterns is presented.

Light Environment in Tropical Rain Forest of Central Amazonia
Provedor de dados: 36
Autores: Brinkmann,W. L. F.
Abstract Light intensity above the groundstoreys (120 cm) and inbetween the ground strata of a Riverine forest, a Carrasco forest and a terra firme Rain forest was recorded through two day periods of time in the rain season (April/May) and the dry season (August) of 1969. Measurements were undertaken between 6 a.m. and 18 p.m. in minute by minute intervals (51.840 readings). The relative frequency of light intensity was computed for seven intensity classes and three periods of time per day.

Notas sôbre os gêneros Polygonanthus e Anisophyllea
Provedor de dados: 36
Autores: Pires,João Murça; Rodrigues,William A.
Summary This paper is a contribution to elucidate an obscure problem which involves relationship of a group of plants containing the genera Anisophyllea, Polygonanthus, Combretocarpus and Poga. Genus Anisophyllea is native in both the Old and New Worlds; Polygonanthus is exclusively Amazonian; and Combretocarpus and Poga are confined to the Old World. It is a very interesting subject relating to the problems of evolution, speciation and distribution of plants, and supports the theories which endeavour to explain the centuries-old story that South America and Africa were, at one time, connected geographically. Taxonomic position of genera Anisophyllea and Polygonanthus is discussed. A new species of genus Anisophyllea is described. General characteristics...

Estudos sôbre a nutrição mineral do feijoeiro (Phaseolus vulgaris L., var. roxinho)
Provedor de dados: 43
Autores: Cobra Netto,A.; Accorsi,W. R.; Malavolta,E.
No presente trabalho foi estudada a marcha de absorção de macronutrientes pelo feijoeiro (Phaseolus vulgaris L., var. roxinho) em condições de campo. Verificou-se que a produção mais alta de matéria sêca ocorreu quando as plantas tinham 56 dias de idade, o que corresponde aproximadamente a dois terços do período necessário para completar o ciclo. As quantidades totais de macronutrientes absorvida em kg/ha foram: N-101, P-9, K-93, Ca-54, Mg-18 e S-25. Em outro experimento foram obtidos, cultivando-se as plantas em solução nutritiva, sintomas típicos de carência dos macronutrientes estudados. Cortes anatômicos das folhas mostraram que a omissão dos elementos do substrato causava lesões nos tecidos, sendo os cloroplastos as organelas particularmente afetadas....

Foi calculada também uma correlação entre o teor de óleo e o extrato aquoso do café torrado. Observou-se que o teor de óleo no café verde variou de 10 a 13% ; no café torrado de 12 a 17% e nas borras do processo caseiro de 7 a 18%. A fração insaponificável do óleo extraido variou de 2 a 5%. As percentagens dos ácidos graxos não variaram acentuadamente de uma variedade para outra, assim como do estado verde para o torrado, podendo-se presumir que a torração pouco afetou êsses...

Capacidade fixadora de nitrogênio de Rhizobiumautóctone associado com soja perene e siratro, em dois solos do Estado de São Paulo
Provedor de dados: 53
Autores: Lopes,Eli S.; Lovadini,L. A. C.; Gargantini,H.; Miyasaka,S.; Leon,José C.
Com o objetivo de avaliar a fixação do nitrogênio atmosférico pela população de Rhizobium sp., que ocorre naturalmente nos solos do Estado de São Paulo e que se associa simbiòticamente com as leguminosas soja perene e siratro, foram conduzidos dois ensaios em vasos de Leonard. Os dados mostram que as populações de Rhizobium sp. presentes em Latossolo Roxo e Latossolo Vermelho Amarelo fase arenosa, sob vegetação natural de cerrado, não fixaram nitrogênio em quantidades comparáveis àquelas devidas à inoculação com estirpes puras. Verificou-se, ainda, influência altamente favorável do cultivo da soja perene na população de Rhizobium que se associa com siratro, presente no Latossolo Roxo.

Autores: Rotta,C. L.; Jorge,J. A.; Oliveira,J. B. de; Küpper,A.
O presente trabalho descreve, ao nível de série, as unidades de solo observadas na Estação Experimental de Monte Alegre do Sul, SP. Essa região, bastante acidentada, acha-se numa altitude que varia entre 700 e 1000 metros, e suas rochas pertencem ao período pré-cambriano, representadas por gnaisses e quartzitos. Outrora de grande importância como zona cafeeira, essa região de novo se reveste de significação econômica, dada a considerável expansão que se está verificando no cultivo de frutas de clima temperado e subtropical, como maçã, pêra, pêssego, figo, morango e outras. De acordo com os critérios adotados na chave de classificação de solos, baseados na côr úmida, espessura das camadas, profundidade, textura, material de origem, presença de recobrimento,...

Exames electrono-microscópicos de secções ultrafinas de tecidos foliares de cenoura (Daucus carota L.) e coentro (Coriandrum sativumL.) infetados pelo vírus do mosaico da cenoura (VMC) revelaram a ocorrência de inclusões em forma de bandas densas no citoplasma. Exames mais detalhados dessas bandas revelaram serem elas constituídas pela justaposição de lamelas delgadas (10-15m¼ de espessura), as quais parecem eventualmente desprender-se e formar outros tipos de inclusão, como as de perfil circular e em forma de catavento, comumente associadas à infecção provocada por vírus do grupo Y da batata. Ocasionalmente, partículas do VMC foram observadas nas proximidades dessas inclusões. As dimensões das bandas densas atingiram até 0,l-0,2¼ x 3-4¼, visíveis mesmo em...

Autores: Lopes,Eli S.; Deuber,Roberto; Forster,Reinaldo; Gargantini,Hermano; Bulisani,Eduardo A.
Um ensaio em Latossolo Roxo foi conduzido para verificar a influência dos herbicidas EPTC e Trifluralin na nodulação e produção do feijoeiro, e, também, a resposta dêste à inoculação das sementes com estirpe selecionada de Rhizobium sp. A análise estatística dos dados coletados mostrou aumento significativo no pêso sêco dos nódulos, devido à inoculação das sementes. O aumento na nodulação não foi acompanhado de incremento significativo da produção. A aplicação dos herbicidas não influenciou a nodulação, mas proporcionou perfeito contrôle de gramíneas invasoras.

Provedor de dados: 53
Autores: Cruz,Luciano S. Paes; Rodriguez,Ody; Igue,Toshio.
Em solo Podzólico Vermelho Amarelo orto, da Estação Experimental de Mococa, foram estudados os efeitos de adubos orgânicos - torta de mamona, estêrco de curral e estêrco de aves - comparados com adubação mineral NP e NPK, todos aplicados em três doses, no desenvolvimento de laranjeiras. Medições efetuadas nos caules, a 10 cm acima do ponto de enxertia, no fim de cada estação do ano, revelaram efeitos positivos das adubações minerais com nitrogênio e fósforo, no desenvolvimento das plantas. A inclusão de potássio não provocou efeitos benéficos, sendo até prejudicial, confirmando resultados de trabalhos anteriores. Os adubos orgânicos não diferiram em seus efeitos e apresentaram melhor resultado quando aplicados na dose intermediária. Seu efeito foi,...

Efeito da combinação de três níveis de espaçamento, três de adubação com NPK e três de tratamento com inseticida, sôbre a produção de amendoim
Provedor de dados: 53
Autores: Tella,Romeu de; Canecchio Filho,Vicente; Rocha,José Luiz V. da; Coral,Fausto J.; Campana,Mário P.; Freire,E. S.
Experiências fatoriais de amendoim com três níveis de espaçamento, três de adubação com NPK e três de pulverização com inseticida foram conduzidas em 1960-61 no Estado de São Paulo. Em média de seis experiências, a adubação proporcionou o maior aumento de produção. A redução do espaçamento também teve efeito satisfatório, ao passo que a pulverização com inseticida pouco aumentou a produção média, pois só apareceram insetos nocivos em duas das experiências. Observações em três experiências mostraram a inconveniência de aplicar o fósforo e o potássio segundo o método tradicional - nos sulcos de plantio.

Variedades de quenafe, plantadas em diferentes espaçamentos, foram estudadas em ensaio instalado em 1968 no Centro Experimental de Campinas, do Instituto Agronômico, visando à produção de matéria-prima para celulose e papel. Produções da ordem de 29,4 t/ha de massa verde renderam 6,7 t/ha de caules secos, que foram estudados, sob diversos processos de cozimento, na produção de pasta para papel. Os processos sulfato e sulfito neutro de sódio revelaram-se apropriados para a obtenção de pasta celulósica de quenafe, dando papéis com boas características físico-mecânicas.

Autores: Teixeira,A. A.; Carvalho,A.; Monaco,L. C.; Fazuoli,Luiz Carlos.
Frutos de café Mundo Novo, colhidos verdes, após o benefício, foram analisados quanto aos defeitos comerciais que apresentaram. A classificação foi efetuada independentemente, por três classificadores, com a contagem de grãos "normais" e daqueles considerados defeitos, isto é, "verde" (três categorias), "ardido" e "prêto". Notou-se uma elevada porcentagem de grãos normais quanto à coloração, e também a ocorrência de grãos dos tipos "ardido" e "prêto", no café não maduro. Com a remoção da película prateada verificou-se uma redução na porcentagem de grãos "verdes" e um acentuado aumento na porcentagem de grãos "ardidos", e um aumento menor na de grãos "normais" e "prêtos". Estas observações indicam que os grãos normalmente classificados no comércio como...

Autores: Gallo,J. Romano; Hiroce,Rúter; Bataglia,O. C.; Moraes,P. R. Püpo de.
Resultados de análises foliares obtidos durante cinco anos em ensaio de adubação química nitrogenada em café, cultivar Mundo Nôvo, instalado em Latossolo Roxo transição para Latossolo Vermelho Amarelo orto, revelaram, para amostras colhidas no verão, teores médios de 2,8% a 3% de nitrogênio total como indicativos de uma nutrição adequada. Produções elevadas de frutos estiveram associadas com teores da ordem de 500 ppm de nitrogênio nítrico nas fôlhas. A análise de fôlhas para ambas as formas de nitrogênio mostrou que a aplicação do adubo nitrogenado em pelo menos três parcelas, no período que vai de outubro a março, parece importante para prevenir a deficiência.

Fragmentos da epiderme inferior de fôlhas de trigo com sintomas típicos da anomalia conhecida como "espiga branca", examinados ao microscópio convencional, mostraram a constante ocorrência de inclusões intracelulares, de dimensões avantajadas e de aspecto fibrilar e enovelado. Freqüentemente, células adjacentes aquelas que continham inclusões apresentavam formações aciculares, em seu interior. Seções ultrafinas dessas folhas, examinadas ao microscópio electrô-nico, revelaram que tais inclusões eram de localização citoplasmática e formadas por uma massa de partículas filamentosas de 7-10 m¼ em diâmetro e de comprimento indeterminado, idênticas àquelas encontradas em preparações "leaf dip".

Microsporogênese em clones normais e tetraplóides de Hevea brasiliensis Muell.-Arg
Provedor de dados: 53
Autores: Conagin,Cândida H. T. M.
Pesquisas sôbre o efeito da colquicina em Hevea brasiliensis Muell.-Arg. realizadas anteriormente levaram à obtenção de clones com número duplicado de cromossomos; tais clones, atualmente em fase de amplas e detalhadas observações (6), floresceram em 1969, pela primeira vez. Foi então realizado um estudo citológico comparativo da microsporo-gènese de duas plantas, uma pertencente ao clone normal n.° 3064, com 2n = 36 cromossomos, e outra pertencente ao clone duplicado n.° 3065, com 2n=72 cromossomos. Ambos são considerados clones gêmeos, porque foram obtidos de uma mesma semente, por técnica especial (7). Na planta com 2n = 36 cromossomos, o processo meiótico é normal, dando tétrades perfeitas e grãos de pólen aparentemente funcionais. A planta 3065, com...

Bambu como matéria-prima para papel: V - Estudos sôbre o emprêgo de quatro espécies de Dendrocalamus,na produção de celulose sulfato
Provedor de dados: 53
Autores: Ciaramello,Dirceu; Azzini,Anísio.
Quatro espécies de bambu do gênero Dendrocalamus (D. giganteus, D. asper, D. latiflorus e D. strictus) foram testadas, em laboratório, para a produção de pasta para papel, através do processo sulfato. Previamente aos cozimentos, determinaram-se as dimensões e os pesos dos colmos, sua densidade básica e as dimensões das fibras. Os cozimentos, efetuados pelo processo sulfato, determinaram rendimento em pasta celulósica branqueável um pouco inferiores àqueles das principais espécies arbóreas usadas para a mesma finalidade. Dendrocalamus giganteus superou as demais espécies, tanto em rendimento como nas características físico-mecânicas do papel.

Provedor de dados: 53
Autores: Gargantini,Hermano; Santos,Dunalvo dos.
Ensaios com soja (Glycine max Merril) foram conduzidos em vasos, nos quais se procurou competir diferentes fertilizantes fosfatados, como superfosfatos simples e triplo e termofosfato, com os produtos Foscal 70-15-15, Foscadu e Foscal 95-5, utilizando-se dois solos diferentes quanto à acidez. Os resultados mostraram excelente resposta ao termofosfato, nos três ensaios, seguido dos superfosfatos simples e triplo, e obtendo-se respostas intermediárias aos outros produtos estudados.

Queda dos frutos do caquizeiro, associada à infestação de Aceria diospyri K. (Acarina, Eriophyidae)
Provedor de dados: 53
Autores: Rossetto,C. J.; Ojima,M.; Rigitano,O.; Igue,T.
A queda dos frutos é um problema grave em caquizeiro. Na variedade Fuyu, uma das mais cultivadas no Estado de São Paulo, a queda chega a 70%. Frutos antes da queda, examinados com binocular de 25 aumentos, mostram entre o cálice e o fruto populações grandes de ácaro eriofiidio Aceria diospyri K. Pulverizações com Sevin (Carbaryl) 85 PM (2 g/l) foram altamente eficientes para o controle dêsse eriofiidio, e o pegamento dos frutos tratados aumentou de 16,1% eni 1967/68, 9,8% em 1968/69 e 25,3% em 1969/70.
