Le chalutage pélagique et notes sur ce chalutage avec panneaux Suberkrub
Provedor de dados: 5
Autores: Portier, Marcel.
Following the trials conducted in 1958/59 by German trawlers, the I.S.T.P.M. tested for the first time, in 1960, on the Roselys, a 120 CV oceanographic research vessel, a pelagic trawl using a boat equipped with a headrope sounder. The trawl was a double panel trawl with an opening perimeter of 500 80 mm meshes. The lateral opening was made through hydrodynamic Süberkrüb doors of 1,7 sq. meters and 130 kg. Finally, an Atlas Werke netzsonde whose oscillator was set on a platform towed behind a headrope, was transmitting information about the opening and sinkage depth of the trawl to the bridge. The cable only had one conductor and the answer was transmitted through the water. Since then, new cables with two coaxial conductors have been used and results are...

La tectonique des plaques
Provedor de dados: 5
Autores: Le Pichon, Xavier.
The plate tectonic hypothesis admits that the orogenic areas, where most of the mechanical energy vanishes, are the areas where the differential horizontal motions between rigid lithospheric plates occur. The success of this hypothesis relies on the fact that the aseismic deformations inside the plates are less important than the motions occurring along the seismic areas. The rigidity of the plates enables a rigorous analysis of their kinematic. This quantitative model of the evolution of the Earth is an incredible revolution in earth science. It leads to a series of new scientific processes and research involving every different field belonging to earth science.

Comparaison de la filtration entre une population de Crassostrea angulata Lmk et une population de Crassostrea gigas Thunberg élevées dans le bassin d'Arcachon
Provedor de dados: 5
Autores: His, Edouard.
L'introduction d'une nouvelle espèce en ostréiculture donne souvent lieu à des débats passionnés dans les milieux ostréicoles. Un exemple est donné par Charles Martin, parqueur du Bassin d'Arcachon, dans son ouvrage "Agriculteur de la mer"; il rapporte les mesures restrictives qu'avait entraînées l'introduction de l'huître portugaise à Arcachon au début du 20ème siècle. Un des arguments avancés pour expliquer les réticences était celui de la "concurrence vitale" et de la compétition sur le plan nutritionnel (filtration) entre C. angulata et Ostrea edulis: cette dernière espèce était alors seule exploitée dans le bassin. Il fallut attendre l'épizootie de 1920, qui anéantit presque totalement l'huître plate, pour que la portugaise soit définitivement admise.

Autores: Comps, Michel.
A few observations were mentioned in an earlier paper (COMPS, 1969) that concerned the histological features of the lesions that appeared during the gill infection to which Crassostrea angulata has been particularly prone since 1966. Since it has, however, not been possible to date to isolate and grow a culture of the parasite presumed to be the responsible agent of the disease, a more complete anatomopathological and histological study was contemplated in order to try to specify the definition of the offending protist and reveal the process of deterioration of the oyster's tissues as well as the reactions of the host to the infestation by and growth of the parasite.  In addition, importing Crassostrea gigas THUNBERG from Japan at the very moment that gill...

Etude comparative par electrophorese de Scomber Scombrus et Scomber Colias

Autores: Bonnet, Marc; Pichot, Paul.
Previous research on the mackerel's blood tissue dealt with, on the one hand, blood groups, and on the other hand, the immunology of serum proteins (BONNET, 1967). Their goal was to bring to light the possible existence of distinct races within the species Scomber scombrus. The study by electrophoresis of serum and crystalline lens proteins was undertaken with this same goal in mind. Its aim was, first of all, to determine biochemical characteristics that have a definite taxonomic value, which led us to compare the protein diagrams of Scomber scombrus and Scomber colias. The results obtained are the subject of this report, in which there are also data on the equipment and techniques used. Later research will consist in seeing whether some of these...

Observations relatives à une expérience de reproduction artificielle des huîtres du Pacifique (Crassostrea gigas Thunberg)
Provedor de dados: 5
Autores: Comps, Michel.
The artificial production of oyster spats in Japan and the USA provided inspiration to some French oyster farmers who thought that, at a time when stocking up Crassostrea gigas spats was getting more difficult, it would be interesting to try out the nutrition techniques developed by Japanese and American specialists. In this way, in La Tremblade, in the Marennes basin, M. Paul Jarno set up some structures aimed at artificial oyster reproduction. Trials started in 1968 and continued in July 1969. The first step was to assess the material and structures' usability and to take a closer look at the practical larval nutrition conditions in order to obtain fixed spats. This document is a collection of the observations carried out during the different trials.

La presqu'île qui s’étend entre les embouchures de la Loire et de la Vilaine, tire une bonne partie de ses ressources de la mer. Aux activités anciennes de pêche et de préparation du sel, sont venus s'ajouter au siècle dernier, la conchyliculture, l'industrie de la conserve de poisson, puis le tourisme balnéaire.  Le tourisme trouve là un cadre de choix avec une côte variée où se succèdent des plages renommées comme La Baule, Pornichet, Batz et Le Croisic, des falaises rocheuses, des plages plus modestes ou équipées, et des ports de plaisance. La part du tourisme augmente dans l'économie de la région. Néanmoins, les activités traditionnelles de pêche gardent un intérêt certain à la fois pour diversifier les sources de revenus de la région, fournir à la...

Quatre ans de mesures volumetriques de plancton total dans le Golfe de Gascogne (1964-1967)
Provedor de dados: 5
Autores: Arbault, Suzanne; Lacroix-boutin, Nicole.
This work is about 14 seasonal campaigns carried out by the oceanographic ships Thalassa, La Pélagia and Roselys in the Gulf of Gascony and the Celtic Sea. It aims to highlight the seasonal quantitative variations of planktonic harvests according to the temperature of the waters. In 1964, four campaigns took place: February (98 stations), May (104 stations), August (101 stations) and November (104 stations), which cover an extensive site, from the headlands of Cornouaille to Cape Finisterre. In 1965, the number of stations was fewer: approximately 22 for each campaign. In 1966 (March: 94 stations, May: 99 stations) and 1967 (March: 125 stations, May: 135 stations, August: 140 stations, November: 134 stations) the sector studied does not include the Celtic...

Selectivite des chaluts en polyamide dans la peche de la langoustine

Autores: Rene, Abbes; Warluzel, Noël.
Net selectivity in fishing the Norway lobster, Nophrops noruegicus (L., 1758), has only until now been the subject of a limited number of publications. Among the authors who have approached the problem, POPE and THOMAS (1965), COLE and SIMPSON (1965), FIGUEIREDO and THOMAS (1967) emphasized the great variability of the results. The research work that we present here does not claim to be exhaustive. It is appropriate, in fact, to emphasize that our data come from a selectivity campaign mainly devoted to hake (DARDIGNAC, HÉDÉ-HAUY and PORTIER, 1968). The trawls that were used on board the Thalassa are very different, as much by their design and their dimensions as by their meshing, from those used on board the small fishing ships that hunt Dublin bay prawn...

Comportement de Crassostrea Angulata lamarck sous des conditions d'asphyxie
Provedor de dados: 5
Autores: His, Edouard.
The oyster's ability to survive in the absence of oxygen is well known. The only means of defence that these sedentary organisms have for fighting against unfavourable environmental conditions or predators is occlusion of the valves. This implies anaerobiosis potential.  This way of life occurs frequently: in the oyster beds, following the most violent storms, the oysters are piled up or covered with sand; they survive in this situation for several days until the oyster farmers put them back to take advantage of the spring tides that enable the drying out of the breeding areas; during periods when the runoff basins are overloaded, the dissolved oxygen content of the sea water are very low and significant mortality rates are sometimes observed in the...

Over the course of the last 20 years, new techniques such as electrophoresis have made it possible to approach the detailed study of proteins; they have found many applications in research on taxonomy. The specificity of serum protein electrophoregrammes, in particular, has been noted by a large number of authors. Nonetheless, the value of serum electrophoresis for taxonomic studies is frequently criticised; indeed, physiological state and environmental conditions can alter the proteinogrammes, by variations in the quantitative distribution of the proteins that are normally present as well as by the formation of new proteins.  Under these conditions, we thought it worthwhile to use protein electrophoresis on another tissue. The research work of RABAEY...

During fishing campaigns for tuna on board the ship La Pélagia in 1968 and 1969 in the Atlantic, between the Gulf of Gascony, the southwest of Ireland and the Azores, the stomachs of caught tunny and those of tunny unsuitable for marking were sampled in order to study their contents at a later time.  This study aimed to clarify certain problems relating to tunny feeding and we were able to highlight an endogenous diurnal rhythm in the white tuna's feeding, which is a new contribution to our knowledge about the biology of this fish. Currently, in fact, the problem of tuna feeding is still poorly understood; whereas the bibliography in this area is relatively rich, it is most often limited to lists of wildlife reports.  In 1932 and 1940, R. LEGENDRE did an...

La faille nord-pyrénéenne : faille transformante liée à l'ouverture du golfe de gascogne
Provedor de dados: 5
Autores: Sibuet, Jean-claude.
It is demonstrated that the northern Pyrenean fault can be interpreted as a transforming fault related to the opening of the Bay of Biscay. This fault follows a circle centred to the north of Paris, and along which the Iberian Peninsula could have slipped. As a consequence, the Bay of Biscay could have opened without creating any compression in the Pyrenean area.

Cartographie des populations de laminaires des côtes françaises de la manche orientale

Autores: Audoin, J; Perez, René.
Il y a plus de cinquante ans, certains océanographes constataient avec étonnement qu'il n'existait pas de carte indiquant la répartition de la flore marine sur les côtes de France. Malgré les excellents travaux de JOUBIN dans la région de Roscoff, ceux de DAVY DE VIRVILLE (presqu'île de Quiberon), les patientes recherches de FLOC'H autour de l'archipel de Molène et celles de DIZERBO (île d'Ouessant), les nombreuses plongées en scaphandre autonome de DRACH et les études de PERES, PICARD, MOLINIER en Méditerranée, les choses n'ont guère changé. Nos connaissances sur la localisation et l'étendue des champs d'algues restent, en effet, extrêmement limitées, surtout en ce qui concerne les peuplements qui n'émergent jamais. Ce fait est d'autant plus regrettable...

Le chalutage pélagique
Provedor de dados: 5
Autores: Portier, Marcel.
Ces dernières années, on a vu se développer, tant à la pêche artisanale qu'à la pêche industrielle, la pratique du chalutage pélagique à un ou deux bateaux. En France, cette technique reste le plus souvent complémentaire du chalutage de fond, que celui-ci soit pratiqué avec un chalut de fond traditionnel ou avec un chalut de fond à grande ouverture verticale ou semi-pélagique, mais quelques bateaux y consacrent déjà une bonne part de leurs activités.  Les premiers essais de chalutage pélagique ont été faits avec le chalut-boeuf ou chalut pélagique à deux bateaux. En effet, ce type de chalut a été utilisé d'une manière commerciale en France dans les ports du Nord, Gravelines et Dunkerque en 1952 et à Boulogne en 1953 pour la pêche artisanale du hareng. Le...

Structures sous-marines des bassins sédimentaires de Porcupine et de Rockall

Autores: Le Pichon, Xavier; Cressard, Alain; Mascle, Jean; Pautot, Guy; Sichler, Bertrand.
In 1921 the "Pourquoi pas?" undertook, under the authority of J. Charcot, an identification of the Rockall bank (2). The petrographic nature of this relief was studied by Lacroix (2) who concluded to aegirine granite dated, since then, by Miller (3) and Sabine (4), from the early Tertiary period. At the beginning of the Noratlante cruise, in August 1969, the "J. Charcot" carried out a number of profiles, tallying the Porcupine and the Rockall area (fig.1). In addition to the gravimetry and magnetism recordings, an oblique-reflection profile and six Flexotir seismic-reflection profiles (with a frequency comprised of between 10 and 30 cycles) were carried out. We only present here the first results based on this last technique.

Poissons des côtes nord-ouest africaines (Campagnes de la « Thalassa » 1962 et 1968)
Provedor de dados: 5
Autores: Maurin, Claude; Bonnet, Marc.
From the second half of the 19th century, several oceanographic ships prospected the northwest coasts of Africa, but they only did so in passing. Their main zone of research was more extensive or farther from European coasts. Under these conditions, the area of knowledge remained limited for a long time, in this region, to shallow waters. Even just ten years or so ago, documents dealing with the ecology and nature of the sea beds more than 200 metres down were rare, in spite of the exploitation of which these sea beds were the target after the end of the First World War. It was to fill this gap, at least partially, that during the year 1962, from 6 November to 12 December, the Institute of Fishing's research ship, the Thalassa, conducted a mission for...

"L'étude de la physiologie de l'huître est d'un grand intérêt pour l'ostréiculture et présente un large champ d'investigations à peine abordé par les chercheurs". Cette opinion était émise par GALTSOFF en 1928, depuis une place de choix a été faite aux espèces américaines Crassostrea virginica et Ostrea lurida essentiellement, à l'espèce japonaise Crassostrea gigas, et à l'espèce européenne Ostrea edulis. Par contre peu de travaux expérimentaux intéressent l'huître portugaise Crassostrea angulata.   Nutrition et respiration, excrétion, dépendent à la fois de l'activité ciliaire de l'épithélium branchial et de l'action du muscle adducteur sur l'ouverture ou la fermeture des valves. D'après GALTSOFF, l'absence de pouvoir de fuite fait que la contraction ou...

Evolution de la salubrité des eaux en baie de Somme
Provedor de dados: 5
Autores: Brienne, H.
La baie de somme s'ouvre sur la Manche entre deux pointes : celle de St-Quentin au nord, celle du Hourdel au sud, distantes de 5 km environ. Elle s'étend sur près de 40 km2 entre les terres basses du pays picard. Son fond de sable vasard est propice à la vie des coques (Cardium edule L.).  Celles-ci forment des gisements presque continus dans sa partie nord et nord-est et sont exploitées chaque saison par environ 200 pêcheurs dont c'est le principal revenu.   La baie reçoit non seulement la Somme, mais encore la Maye et une série de canaux qui drainent les marais riverains. Elle collecte ainsi plus ou moins  directement les eaux usées des agglomérations voisines : Rue, Le Crotoy, Abbeville et Saint-Valéry-sur-Somme (fig. 1).  Le déversement des eaux douces...

La marge du Grand Banc et la fracture de Terre-Neuve
Provedor de dados: 5
Autores: Auzende, Jean-marie; Olivet, Jean-louis; Bonnin, Jean.
Some seismic and magnetic profiles carried out south of the Big Bank of Newfoundland during the Noratlante cruise show a fracture zone which collapses the continental margin and continues to the south-east towards the Azores. This fracture zone proves evidence of the drift movement of Africa towards the east during the Jurassic or Trias opening of the Atlantic. From the south-east corner of the Big Bank, the fracture zone supports a sediment ridge formed by the underflows and which continues to the meridian 430 West.

Autores: Guichet, Roger; Meriel-bussy, Mireille.
During its seasonal campaigns from July 1965 to November 1967, the Thalassa performed 190 trawl passes in the Gulf of Gascony. These catches, spread out from 35 to 300 metres between the parallels of 44"50' and 47°50' N, showed some similarities between the hake's and the blue whiting's distribution. The highest yields of one frequently match high quantities of the other and vice versa. However, this link is not so clearly demonstrated in all seasons. Moreover, we have noticed that the average weight yields of the two species increase steadily with depth (figure 1). Only sea beds of 180 metres provided different results: whereas blue whiting is in especially large numbers there, hake is less present than at neighbouring levels. It seemed worthwhile to us...

The progressive reduction of the Cardium edule's (shell) areas of distribution in the Arcachon basin had led us, at the beginning of the year 1968 and after fishing season to become interested in the problem of the survival and exploitation of the only existing significant site in the most oceanic part of the bay, the Arguin bank's cove. The topographical features of the environment have been described elsewhere (DELTREIL and His, 1968). During this preliminary study, our observations had enabled us to define the factors responsible for the survival and growth of this population of shells. Competition from Mytilus edulis and the instability of the beach mean that maintaining this site is closely linked to a regular and abundant annual intake of spat.  It...

La dorsale medio-atlantique et le renouvellement des fonds océaniques
Provedor de dados: 5
Autores: Pautot, Guy.
There is an important gap between marine studies based upon geophysics and field geology, which fundamentally remains at a descriptive level. If we want to reach a general understanding of the earth history, we must consider all the informations from land and oceanic areas. This short paper is an attempt to draw the attention of geologists upon the data acquired in oceanic areas. From the example of the mid-ocean atlantic ridge (studied through geophysical and geological methods), the theories of sea floor spreading and plate tectonics are exposed. Considering these theories, a model for the origin of the Atlantic ocean can be established. Obviously, the atlantic origin depends on compression, distension and shear strength phenomena, that have had an...

La faille transformante Gibbs entre le Rift et la marge du Labrador

The Gibbs fracture moves the central Rift of the Mid-Atlantic Ridge 370 km to the left at latitude 53O north. It is the only fracture located between Europe and America that can be compared to the large equatorial fractures mapped by B.C. Heezen and M. Tharp between Africa and America. Its morphology is a major element in the understanding of the structural framework of the northern Atlantic Ocean. The identification of its extension to the west was one of the proposed focuses for the first Noratlante expedition of the R.V. Jean-Charcot (conducted in August 1969 under the authority of the C.N.E.X.O.). J.T.

Only fifteen or so years ago, the geology and sedimentology of the Gulf of Gascony was not at all well known. Dredging was rare and the only systematic readings of the nature of the sea beds were given by the Hydrographic Service's probes. It is based on this information that DELESSE (1872) made the lithologic map of the French seas, revised and supplemented by THOULET in 1904.  In 1955, BERTHOIS published the first summary research. He used dredgings from various campaigns, Pourquoi-Pas?, Quentin-Roosevelt, President Theodore Tissier, and resumed the previous research work of DANGEARD (1928), FURNESTIN (1937) and BERTHOIS (1946).

Introduction. L'exploitation commerciale des crustacés, et en particulier des crevettes, a connu un développement considérable à partir de 1950. L'augmentation constante des apports est liée à une demande croissante sur les marchés et l'intérêt s'est porté vers de nombreuses espèces qui ne subissaient à l'origine qu'une exploitation locale.  Parmi ces espèces, Pandalus borealis, caractérisée par sa vaste distribution dans l'Atlantique nord, a reçu plusieurs noms vernaculaires. Elle est appelée "pink shrimp" ou "crevette rose" aux Etats-Unis, alors que ce terme désigne aussi bien une grande crevette du golfe du Mexique et de Guyane qu'une espèce des fonds rocheux côtiers européens.

Considering the current state of research in this area, creating a programme like this could be designed in four successive stages: 1) Schematic map: survey and systematic run of the coast; 2) Detailed map of the shoreline's flora; analysis of aerial photographs; 3) Detailed map of the infralittoral flora; deep-sea diving; 4) Overall map of the marine vegetation of France's coasts: summary of the results, colour printout.

Essai de classement bathymetrique des formes zooplanctoniques en mediterranee
Provedor de dados: 5
Autores: Casanova, Jean-paul.
Research on the vertical distribution of zooplankton in the western Mediterranean is still rare. With the exception of the Thor's campaigns covering the whole of the two basins, vertical fishing has long remained rare and localised. Nonetheless, for some ten years now the practise has been growing, from combined deep harvests to hydrological reports. It is in this context that the Institute of Maritime Fishing carried out, with the oceanographic ships President Theodore Tissier in 1958 and Thalassa in 1961 and 1963, several series (respectively K, N, and P) of vertical samples, at various levels throughout the western basin, but most especially in the Ligurian-Provençal channel and in the central sector (figure 1) that are the subject of this paper.

Ecologie des crustacés péracarides des fonds rocheux de Banyuls-sur-Mer. Amphipodes, isopodes, tanaidacés, cumacés infra et circalittoraux
Provedor de dados: 5
Autores: Chardy, Pierre.
The present work is an ecological study about Peracarid Crustaceans living on rocky bottom in infra and circalittoral zone.  A sampling method for hard bottom is presented in the first part.  A biocenotic study permits, in a second part, to describe the distribution of the populations. Affinity index values, computed by Bravais-Pearson correlation coefficient, show three faunal associations assigned to the upper-infralittoral, deep-infralittoral and circalittoral zone. The relations between species and environment are studied by mathematical approach.  A multiple linear regression analysis shows the influence of light penetration and turbidity factors. A factor analysis gives two principal components, interpreted as biotic environment and density of...

Cinématique de la tectonique des plaques
Provedor de dados: 5
Autores: Le Pichon, Xavier.
The success of what can now be called, since the Joides drillings, the F.J. Vine and D.H. Matthews theory lead to the formulation of a hypothesis giving way to a kinematic description of the current tectonic activity on the surface of the earth. This hypothesis, the plate tectonic, admits that the orogenic areas, where most of the mechanical energy vanishes, are the areas where the differential horizontal motions between rigid lithospheric plates occurs. The success of this hypothesis relies on the fact that the aseismic deformations inside the plates are less important than the motions occurring along the seismic areas. The rigidity of the plates enables a rigorous analysis of their kinematic.

L'emission des gametes chez l'huitre portugaise (Crassostrea Angulata LMK)
Provedor de dados: 5
Autores: His, Edouard.
LE DANTEC (1968), in his research on the ecology and reproduction of the Portuguese oyster in the Arcachon basin, recounts a few experiments involving heat stimulation of genital product emissions. He conducted them in order to confirm his observation in situ, since temperature variations are presumably the most common factor of external stimulation in nature. However, the act of emitting male or female gametes in Crassostrea angulata was not, to our knowledge, the subject of any special study. In a general way, the authors seem to admit that it is possible to extend to the entire Crassostrea SACCO species the results obtained about C. virginica, C. gigas and C. commercialis, mainly by American and Japanese researchers. We wanted to verify it for the...

Continuous Deep Sea Salt Layer along North Atlantic Margins related to Early Phase of Rifting
Provedor de dados: 5
Autores: Pautot, Guy; Le Pichon, Xavier.
Deep seismic reflexion surveys have revealed diapiric structures in deep water off Labrador, Newfoundland, Mauritania, Morocco, Portugal, Spain and lreland as well as in the Mediterranean. Many of these diapirs are similar to the Gulf of Mexico salt domes, and it is suggested that there is a continuous deep sea sait layer, off the continental margin, which is related to the early phase of rifting.

Répartition bathymétriqué des euphausiacés dans le bassin occidental de la méditerranée
Provedor de dados: 5
Autores: Casanova, Bernadette.
The data on the vertical distribution of Euphausiacea in plankton catches can lead one astray about the true behaviour of these organisms, either that the samples were done at night and with nets that do not have a closing system, as in some of the Thor nets, or that the device worked along the entire water column, from the bottom to the surface, without level accuracy. A painstaking examination of the quotes is therefore necessary. We have already done a detailed analysis of the data of authors prior to 1968 for all Mediterranean species (CASANOVA-SOULIER, 1968a). We are proceeding here with the interpretation of our personal results, the whole of which has led us to draw up a very complete table of the vertical distribution of Euphausicea in the western...

This work is based upon a collection of Annelida Polychaeta assembled from the Mediterranean Coast of Israel during an ecological experiment on fouling. The present paper describes a new species of spionid, Prionospio salzi sp.nov. Some morphological and biological peculiarities lead to the conclusion that all specimens of P.salzi are old larvae. The systematic position of this species within the large genus Prionospio is considered. [NOT CONTROLLED OCR]

La marge continentale algérienne et le phénomène de subsidence : exemple du Golfe de Bougie
Provedor de dados: 5
Autores: Auzende, Jean-marie; Pautot, Guy.
The study of a continuous seismic-reflection profile (Flexotir) carried out in the central part of the Bougie gulf, enabled the identification of a thick sediment series leaning on the continental basement and continuing underneath the abyssal plain. On the one hand, this series contains a formation (D) thought to be a Miocene salt layer, and on the other hand, it keeps the trace of some upheaval and subsidence movements which define the recent tectonic history of the Bougie gulf. No trace of the current compression phenomenon between the Eurasian and African plates could be found.

La fracture Gibbs et la circulation profonde en Atlantique Nord
Provedor de dados: 5
Autores: Olivet, Jean-louis; Le Pichon, Xavier; Laubier, Lucien.
The cold waters from the Norwegian Sea are the main source of the underflow system in the northern Atlantic Ocean (10) (pl. 1, fig. 1b). The role of these currents in the formation of large sediment ripples has been demonstrated in some recent studies [(2), (3)]. As in the southern Atlantic Ocean, the observations suggested that their influence had been of importance since the Eocene era (6). From a sedimentological point of view, it appears that the Gibbs fracture (4) represents a very important feature in this system; this structure both forms a deep opening through the Mid-Atlantic Ridge and a dam across the abyssal plain to the northeast of Newfoundland. This dam, which is still active today, though partly flooded, must have been continuous from the...

Remarques sur quelques cephalopodes mésopelagiques du Golfe de Gascogne
Provedor de dados: 5
Autores: Abbes, Rene.
The teuthological fauna of the Gulf of Gascony is still very imperfectly understood, especially in the pelagic area. The major expeditions have rarely worked east of the line that links the Grand Sole to the reefs of Cape Finisterre. The data that we have available for the region come from independent observations by H. FISCHER and L. JOUBIN (1906) and by L. JOUBIN (1895, 1900, 1920 and 1924). The most important research work is thanks to J. BOUXIN and R. LEGENDRE (1936), who studied very many stomach contents of tunny.  In 1966 and 1967, the Thalassa had the opportunity to conduct 17 deep pelagic catches using an Isaacs-Kidd net, at immersions spaced out between 500 and 1,600 metres. They brought in twelve species of cephalopods: Heteroteuthis dispac...

Sprinkler Irrigation
Provedor de dados: 18
Autores: Pair, C.H.
Sprinkler irrigation systems distribute water by  spraying it over the fields. The water is piped under  pressure to the fields. The pressure forces the  water through sprinklers or through perforations  or nozzles in pipelines and thus forms a spray.  Sprinkling is man's imitation of natural rainfall.  Nearly all irrigable soils can be sprinkler irrigated.  It is difficult, however, to sprinkler-irrigate  if the water intake rate of your soil is less than  0.10 inch per hour.

The Winteraceae of the Old World. I. Pseudowintera and Drimys — Morphology and taxonomy
Provedor de dados: 16
Autores: Vink, W.
The primitive woody Angiosperm family Winteraceae is centred in the southwest Pacific, has an outpost in Madagascar (1 species), and a section of Drimys (4 species) in the New World. Pseudowintera is restricted to New Zealand, the Old World section Tasmannia of Drimys extends from the Philippines to Tasmania. Since A. C. Smith’s review of the family in 1943 about ten times as much material has become available and it appears that the taxonomy of the section Tasmannia is far more complicated than it seemed to be in 1943. This induced me to make a field study in New Guinea and to pay special attention to its morphology in the hope of finding additional criteria. On this basis the Australian species of Drimys could be better defined but the characters of the...

Variations of body temperature and metabolism during entrance into cold lethargy in the bat Myotis myotis
Provedor de dados: 16
Autores: Heldmaier, Gerhard.
Bats of temperate zones which hibernate during winter become cold-lethargic during their diurnal rest time even in summer. At the end of their nocturnal activity period they show a drop in body temperature close to ambient temperature (M. myotis, cf. Pohl, 1961). This takes place periodically even if the bats are kept in constant darkness (Eptesicus fuscus and Myotis lucifugus, cf. Menaker, 1959, 1961). The daily drop in body temperature is not simply the result of one single reduction in heat production, but seems to be a more complicated process since EKG-records during entrance into cold lethargy (Kulzer, 1967) showed increases and decreases in heart frequency which can be related to a regulatory activity of the sympathetic nervous system. Normothermy,...

Notodelphyidae and Botryllophilidae (Copepoda) from the West Indies
Provedor de dados: 16
Autores: Stock, Jan H.
Notodelphyidae and Botryllophilidae are families of cyclopoid copepods, usually associated with Tunicata. Although SARS (1921) considered the families closely related, and placed them together in his suborder Notodelphyoidea, LANG (1946) showed that this group was polyphyletic. The two families are treated here together, simply because both are associated with the same host group. Through unforeseen circumstances (loss of part of the material while sent out on loan), the publication of this paper was considerably delayed. Certain details that had to be checked, could not be verified owing to the loss of the material involved. In my opinion, however, the available data are still of sufficient interest to warrant publication.

A redefinition of Gastonia and related genera (Araliaceae)
Provedor de dados: 16
Autores: Philipson, W.R.
The six genera Gastonia, Tetraplasandra, Reynoldsia, Munroidendron, Peekeliopanax, and Indokingia form a natural complex distributed from East Africa to the Marquesas and the Hawaiian Islands. The characters which have been thought useful in distinguishing these genera are re-examined. The distinction between Gastonia and Tetraplasandra is redefined, emphasis being placed on the radiating stigmatic arms in the fruit rather than on pleiomery of the stamens. On this basis Tetraplasandra is confined to the Hawaiian group. The monotypic genera Peekeliopanax and Indokingia are reduced to synonymy under Gastonia, which thus comprises all species of the complex west of Samoa.

A contribution to the knowledge of non-marine Mollusca of South West Africa
Provedor de dados: 16
Autores: Bruggen, A.C. van.
The moment to collate scattered notes on South West African non-marine molluscs arrived last year when Mr. B. H. Lamoral of the Natal Museum, Pietermaritzburg (South Africa), entrusted the present author with the study of material obtained during a Council of Scientific and Industrial Research (C.S.I.R., Pretoria)-sponsored collecting trip. During Mr. Lamoral's explorations in 1969 in South West Africa non-marine molluscs were obtained as a sideline. Nevertheless the material is certainly considered sufficiently interesting to warrant publication. South West African material from various sources was studied and the following abbreviations have been used: BM for British Museum (Natural History), London; NM for Natal Museum, Pietermaritzburg; RMNH for...

The use of a precipitin test to determine host preferences of the vampire bats, Desmodus rotundus and Diaemus Youngi
Provedor de dados: 16
Autores: Greenhall, Arthur M.
Vampire bat rabies is one of the greatest deterrants to the raising of livestock in Latin America. To know more of the epizootiology of the disease as well as to understand the ecology of the vampire bat family, Desmodontidae, detailed information about their feeding habits and host preferences is essential. Vampire bats feed exclusively on blood. Examination of probable host animals for bat bites has been the primary method used to determine their victims. More reliable precise data are achieved by serological analyses of the digestive tract contents of vampires killed after attacking their hosts. Precipitin test techniques were used similar to those devised for the identification of blood meals of bloodsucking arthropods (Weitz, 1952, 1956, 1960;...

Autores: Geijskes, D.C.
This study contains the results of an examination of the Corduliidae found in the Guyanas. It is based on a critical study of the data as published mostly in the older literature and on the identification of the material brought together in Surinam in the years 1940 to 1965 by Mr. J. Belle and myself, beside some specimens picked up in French- and in (Br.) Guyana. Comparison of three types in the Selys collection in the Brussels Museum, of one in the Fraser collection in the British Museum (Nat. Hist.) in London and of one kindly received from the Museum in Berlin was necessary to eliminate further confusion. It now became clear that, so far as the material goes, one genus (here described as new) belonging to the Gomphomacromiinae and two genera of the...

Provedor de dados: 16
Autores: Wijsman-Best, Maya.
A new species of Madreporaria, Polycyathus fulvus, is described from New Caledonia. Zooxanthellae have been found symbiotic in its polyps, although the genus is ahermatypic. Another Polycyathus, P. senegalensis Chevalier, 1966, is recorded from the Caribbean area; it was previously known from the eastern tropical Atlantic only. These two records extend the known range of the genus and show it to have a circumequatorial distribution in warm and warm-temperate waters.

This volume covers entries from the letters Ph—Re of this Cyclopaedia, which next to entries on plants (457 in all) contains also entries on minerals and animal products. Plants are arranged alphabetically under generic names. The impression is that plants are more lavishly treated in detail than the two other categories which together cover only 28 pp. The other 7 volumes also contain mainly botanical information; 90 % of the total entries being botanical. The series is essentially a modem treatment of George Watt’s ‘A Dictionary of the Economic Products of India’, 1889—1893, 6 vols.; a very large amount of information from an enormous literature is digested in this modern account. General information is given on a fairly large number of genera which are...

The Rijksherbarium received this finely illustrated book from Mr. Anghelos N. Goulandris, chairman of the Board of Governors of the Goulandris Botanical Museum, Kifissia, Greece. In the accompanying letter Mr. Goulandris wrote that this is the first publication of the recently (1963) founded Museum, an institution which has the object of promoting and assisting plant taxonomic activity and research in Greece. The beautiful botanical paintings were made by Mrs. Niki Goulandris, of Athens. They depict many Greek endemics but also species of a much wider distribution. All illustrations are, however, as the author’s introductory note says, of outstanding native wild flowers, especially collected for this purpose by the late Dr. C. N. Goulimis, who also drew up...

According to Hutchinson this is intended as a Companion or Supplement to the first volume of the 2nd ed. of his ‘Families of Flowering Plants’ (1959), which lacked room for notes on phylogeny or genera with outstanding characters. ‘These are now provided with illustrations of many plants of special morphological interest and economic importance, and which sometimes may lead to their identification (sic). Drawings of the type species of the type genus of most of the large families are also included. The illustrations are mostly my own work’. The illustrations, at once simple and carefully made, are a pleasure to the eye and interesting indeed as a large number either depict little known ‘aberrant’ genera or give in some families (Cruciferae, Leguminosae,...

Volumetric comparisons of brain structures in bats (an attempt at a phylogenetic interpretation)
Provedor de dados: 16
Autores: Stephan, Heinz; Pirlot, Paul.
Bats show, in spite of the unity which they derive from the unique possession of flight-ability, remarkable differences in their encephalization (Pirlot &amp; Stephan, 1970). These differences were found to be more closely related to feeding habits than to systematic relationships. The brains of the insect hunting species show the lowest degree of encephalization when treated with the allometry formula. Then, in ascending order, come the nectarfeeders, the frugivorous Microchiroptera, the fisheaters, the vampires and finally the frugivorous Megachiroptera. The present analysis of a variety of parts of the brain confirm the close relationships between characteristics of the brain and feeding habits. Therefore, in spite of the relatively restricted material,...

The genus Conocybe subgen. Pholiotina. I. The European annulate species
Provedor de dados: 16
Autores: Kits van Waveren, E.
Sixty-five collections, comprising all known European annulate species of Conocybe, subgenus Pholiotina, were examined, including the type specimens of C. vexans P. D. Orton and C. percincta P. D. Orton. In accordance with Orton, it is argued that Ricken, Kühner, and several other authors reversed the original conception of C. blattaria and C. togularis, as used by Fries, but that the specific epithet ‘togularis’ should be replaced by ‘arrhenii’. Conocybe aporos and C. arrhenii var. hadrocystis are described as a new species and a new variety respectively. It is argued that C. vexans is conspecific with C. blattaria, and C. percincta with C. teneroides. Singer’s observation—hitherto the only one of its kind—that 2-spored basidia may occur in C. pilaris was...

Distally lobed integuments in some Angiosperm ovules
Provedor de dados: 16
Autores: Heel, W.A. van.
In this treatise ‘De l’Ovule’ Warming (1878) remarked that although the borders of the integuments grow uniformly, very rarely a division into lobes can be observed. He mentioned Symplocarpus foetida (inner integument four-lobed), Lagarosiphon schweinfurthii (outer integument four- or five-lobed) and Juglans regia (two-lobed). Moreover he cited the report by some authors of an occasional occurrence of lobed integuments in a few more plants. More recently Leroy (1955) described bilobed single integuments in Juglans and Platycarya. Boesewinkel and Bouman (1967) demonstrated that these lobes arise as two separate primordia in Pterocarya and Juglans.

The Research Institute for Nature Management (R.I.N.) has compiled all available information on the distribution of bats in the Netherlands up till 1968. The data were derived from literature and museum specimens, as well as from numerous unpublished observations. Around 1960 much was known already on the winter dwellings of various species of bats, especially those in marl pits and fortresses. Less details were available concerning the distribution of bats in summer. Only one species, Nyctalus noctula, had been studied during the summer. During the past ten years valuable information on hibernacula could be added by continued research in marl pits and fortresses, and by investigations in cellars of castles and in former ice cellars.

This paper presents a pollen-morphological study of Alangium, a genus mainly restricted to the tropics of the Old World, of which 18 of the 19 known species were studied. The pollen grains, studied with the use of a light microscope, a transmission electron microscope and a scanning electron microscope, were classified into 15 pollen types, to which a key is given. Comparison of fossil and recent grains produced some information about both the evolutionary trends in the characters of the pollen grains and the phytogeography of Alangium.

In the introduction to his work the author explains the need for Icones of Indian Algae. He mentions several old publications with excellent illustrations in colour of marine algae from other coasts, which have added considerably to the knowledge and wider appreciation of the organisms. ‘Phycologia Indica’, unfortunately, is inferior to most of these older works. This is not because the coloured plates are of inferior quality. Some of them are even perfect, like those of Sebdenia polydactyla (pl. 14), Halymenia porphyroides (pl. 17), Grateloupia indica (pl. 19) and Dictyopteris australis (pl. 34).

Thickness variations of the lower member (nodular limestones) and the upper member (limestones) are of minor importance, whereas the middle member (quartzite-dolomite alternation) is wedge-shaped: its thickness decreases over a distance of about 35 km from about 100 m (50 m of which are quartzites) in the west to 0 m in the east. In the surrounding areas the Basibé Formation consists solely of limestones. Carbonates were deposited as lime muds in shallow, open marine environments. Mature quartz sands,...

The present paper deals with some gomphids from South America. Besides descriptions of a number of new species additional notes on several Selysian and other, little-known species, elucidated with illustrations of important details, are offered in order to obtain a better insight into the characteristics of these dragonflies. Lectotypes are selected and confusions in respect to the generic or specific status of some species are unraveled. Of nearly all the gomphids from Surinam the larval stages are described or discussed. The identity of several larvae is ascertained by the actual rearing of some individuals. The discovery of two new Agriogomphine species resulted in a classification of the members of the Agriogomphus complex into two genera only instead...

Two species of Biscutella, viz. B. auriculata L. and B. didyma L. are known as aliens in the Netherlands. They can be distinguished from each other as follows: 1. Petals c. 10—15 mm long, with a long claw. Outer sepals saccate at the base. Silicula not emarginate at the apex, but narrowed into the style .............. 1. B. auriculata L. 1’. Petals c. 3—5 mm long, with a very short claw. Outer sepals not saccate. Silicula emarginate at the apex .............................. 2. B. didyma L. Of B. didyma both var. leiocarpa (DC.) Halacsy (glabrous fruits) and var. ciliata (DC.) Halacsy (fruits with ciliate margins and sometimes with short hairs on the valves) have been found.

Lizards of the genus Cnemidophorus from the Leeward Group and the adjacent mainland of South America
Provedor de dados: 16
Autores: Lammerée, Liesbeth.
When WAGENAAR HUMMELINCK (1940, p. 83—85) made a survey of the lizards of Curaçao, Aruba, Bonaire and the Venezuelan Islands, he could give no more than a short list of specimens collected, together with a few critical remarks, and a single table on “Variation in Cnemidophorus” based on 379 specimens. In later years more material has been collected by the same investigator in the same region, which has been entrusted to the author for further study. This enabled her to give special attention to a few data which have been disturbing the zoogeographical concept of the lemniscatus-group for a long time already. It has been known for quite a while that the species Cnemidophorus lemniscatus has a remarkably uniform distribution along the northern coast of South...

Studies in the family Thelypteridaceae II. A comparative study of the type-species of Thelypteris Schmidel, Cyclosorus link, and Ampelopteris Kunze
Provedor de dados: 16
Autores: Holttum, R.E.; Sen, U.; Mittra, D.
In the first paper of this series (Holttum, 1969) I gave a brief summary of taxonomic treatment of the family Thelypteridaceae in the present century, and stated that in my judgement no satisfactory subdivision of the family, as represented in the tropics of the Old World, had yet been achieved, the arrangements of Ching (1963) and Iwatsuki (1964) being in part inadequate because the authors were not sufficiently acquainted with the majority of species in the Malayan region and in the Pacific, which far outnumber those of mainland Asia. I have been attempting a complete survey of all species of Asia, Malesia, and the Pacific, and it has become evident to me that a study of a wider range of characters than those used in most taxonomic species-descriptions...

Autores: Held, A.J. den; Held, J.J. den; Maier, E.X.
In the late summer of 1969 an investigation was made on water plants and vegetations of these in the peat holes of De Haak, part of the Nieuwkoopse Plassen (province S. Holland, the Netherlands). The pools are situated in marshwood peat and mostly have a thick layer of sapropelium. The water is about 1 m deep, is slightly oligohaline, has a medium calcium content, and is as yet hardly polluted. In the south the peat holes communicate with a ditch containing water which is comparatively rich in phosphate and nitrite. The increase in pollution and in the phosphate content to the south is demonstrated by the growing abundance of Ceratophyllum demersum and/or Vaucheria cf. dichotoma Ag., accompanied by species such as Elodea nuttallii and Lemna gibba.

Autores: Reed, Charles A.; Borowsky, Richard.
In this short paper we list the herpetological specimens collected in southern Surinam (Dutch Guiana) by Mr. and Mrs. Rudolf Freund in November and December, 1961, and include ecological notes made by the Freunds at the time. This area is one from which collections are rare, so that distributional data are generally unavailable. Of special interest is the seemingly common occurrence there, and in adjacent parts of Guyana (formerly British Guiana), of giant specimens of the toad Bufo marinus, of such length and weight to indicate that these animals are the “world's largest toads”. The collecting localities are shown on the outline map (Fig. 200) and available habitat data are given in the species list.

Competition in three Cyprinodont fish species in the Netherlands Antilles

Autores: Kristensen, Ingvar.
Cyprinodon dearborni, Poecilia sphenops and Rivulus marmoratus seem to fill almost the same niche. In most of the landlocked bays, lagoons or pools the three species were not found together. In only two landlocked locations two of the species were found together. In the locations with an open connection with the sea all three species, or at least two were present. In landlocked waters interspecific competition seems to play an important role as the niches of the three species overlap to a large extent. Environmental factors of importance appeared to be: 1) Plant or algal growth is required by Poecilia and Rivulus. 2) Low salinities seem to be of advantage to Poecilia and Rivulus, supersaline environments seem to favour Cyprinodon. 3) Oxygen depletion may...

This new hard-cover Flora of Barbados is in every respect a fine specimen of a local tropical flora. The black and white frontispiece is by Priscilla Fawcett, representing the ‘Barbados Pride’ (Caesalpinia pulcherrima). Concise in design, limited in consequence of the small space of the area concerned, hence restricted to a rather small number of species slightly over 600, this book dealing with Spermatophytes is of great value, supplying a long-felt need for a modern flora ‘by students, teachers, agriculturists, as well as by amateur botanists, whether residents or only visitors to the island’. It does not pretend to be more than it aims at: ‘to enable anybody with only a slight knowledge of botany to identify any wild Flowering plant he or she may come...

Der Elevations-Effekt bei einigen Taraxacum-Arten der Schweiz
Provedor de dados: 16
Autores: Backhuys, W.
In continuation of a former study on the ‘Elevation Effect’ in the Swiss mountain flora (Backhuys, 1968), the distribution of six Taraxacum species in Switzerland was examined in detail. This was enabled by the preceding monographic study by J. L. van Soest (1969). The interesting point was to compare species of one genus with a common dispersal mechanism. Data on the vertical distribution are provided in table I and diagrams 1—6. It was found that all six species show an elevation effect which varies from 200—750 m. In five species this range is as narrow as 500—750 m. See table II. It is concluded that in spite of the very obvious dispersal mechanism (parachute-achenes) the species are apparently not capable to colonise ‘mountain islands’ the summit...

Autores: Meijden, R. van der.
In his paper on the peat swamp forests of Sarawak and Brunei (Gard. Bull. 20, 1963, 152) Dr. J. A. R. Anderson made notice of a distinctive Xanthophyllum species which he was not able to identify. In 1968, Mr. F. S. P. Ng, revising the genus for the Manual of Malayan Timber Trees, recognized it as a new species, but did not describe it. Working now on a monograph of the genus, and having examined all collections Dr. Anderson kindly sent on loan to me, I am able to describe it here as a new species. I am much indebted to Dr. H. Sleumer for rendering the diagnosis in Latin.

The hyphomycetous genus Phialophora is revised. It is characterized by flask-shaped phialides with a collarette and one-celled slimy conidia. This characterization excludes species which form blastospores on sympodulae besides phialospores, and which have been revised as species of the genus Rhinocladiella in a previous paper. The genus Margarinomyces, on the contrary, is considered to be a synonym of Phialophora. With this emendation there remain now twelve species or species groups which are redescribed. The necessary new combinations are proposed.

Duabanga taylorii Jayaweera (Sonneratiaceae) a putative hybrid
Provedor de dados: 16
Autores: Geesink, R.
The differentiating characters of Duabanga grandiflora (Roxb. ex DC.) Walp., D. moluccana Bl., and D. taylorii Jayaweera are given. Most characters of D. taylorii appear to be intermediate between those of the other two species; a few characters represent combinations of those of the two other species; one character is not shared by the other species. From this evidence it is supposed that D. taylorii is a hybrid. This suggestion is sustained by the history of the specimens on which D. taylorii is based. An attempt to count chromosomes of D. taylorii and D. grandiflora failed, probably due to the unsuitability of the fixative for this purpose.

Rumphius (Herb. Amboin. 3, 1743, 19, t. 7) was the first to use the name Metrosideros, but of the 6 species he listed only the first, M. vera, belongs to the Myrtaceae. The same species is assumed to be the basis of Nani Adanson (Adanson, Families des Plantes 2, 1763, 88). Adanson did not list any species, but the assumption is based on the description and the fact that Rumphius had given the vernacular name of his Metrosideros vera as ‘Nani tree’.

Autores: Zuuren, A. van.
The area around Santiago de Compostela has been subjected to petrological and structural investigations. The rocks present in the mapped area have been divided into two complexes (the Ordenes Complex and the Complex of Santiago de Compostela) on the basis of their petrography, structure and grade of metamorphism. An additional group consists of the intrusive rocks still recognizable as such. The intermediate-grade rocks of the Ordenes Complex mainly comprise retrograded mafic granulite-facies rocks, garnet-amphibolites, amphibolites, metagabbros, peridotite and kyanite-staurolite-garnet-gneisses or schists. Part of these rocks underwent amphibolite-facies metamorphism during a probably pre-Hercynian orogeny and in places granulite-facies conditions were...

Judging from the volume here reviewed it is to be expected that this atlas will become a splendid comprehensive survey of the ‘seeds’ of the NW. European Phanerogams. The complete work is planned to consist of 4 or 5 parts, of which part I will be published last, as it will contain general information and keys to the families. It is self-evident that the keys to the genera of Cyperaceae, to their sections, and in large sections to the species, wholly based on fruit-characters, cannot be easy. In random testing they proved to be reliable, as are the accurate descriptions.

All Copepoda Calanoida, with the exception of nauplii, have been removed from the sample and have been identified, many of the copepodids only as far as the genus. Though many Copepoda have now been described from the Pacific Ocean and the number of samples studied has reached a considerable total, its copepod fauna, particularly that of the deeper strata, is still far from satisfactorily known. This pertains particularly to the northern Pacific, an area which, in comparison to the extensively studied northern Atlantic,...

The age composition of a sample of a Stoat population from the Netherlands was studied. Various relative age criteria were tested on their validity in separating age groups. The study of the layered cemental deposits contributed the most important part to the final conclusions. By using also the data on the sexual cycle of the Stoat, a theoretically expected age pyramid was calculated, which was compared with the actually found age composition.

For different species of bats, fixed in 5 % formaldehyd, an estimation of the number of neurons in the spiral ganglion was made. The cochleae were decalcified in EDTA and embedded in paraffin. The complete series of sections were stained with hematoxylin. On the sections through the ganglion, the number of ganglion cell nuclei was determined, with the help of an eye-piece micrometer. A 200 times magnification was used. The figures obtained with this method were corrected, with the help of Floderus’ formula: N = n.

INTRODUCTION In this second part of my series of papers on the genus Linyphia sensu Bonnet (1957) two genera are dealt with which have been removed from Linyphia Latreille on morphological and ethological grounds. The functioning of the genitalia of one example of either genus have been described and discussed in the first part (Van Helsdingen, 1969). Though the results were not as striking as in the case of Neriene versus Linyphia, the study of the functional aspects of the genitalia have added much to the understanding of the correlations between the shapes of the different parts of the male and female secondary sexual organs. Neriene was separated from Linyphia largely on the basis of the differences in the functioning of the genitalia, as revealed in...

The South American catfish genus Brochis Cope, 1872 (Pisces, Siluriformes, Callichthyidae)
Provedor de dados: 16
Autores: Nijssen, H.; Isbrücker, I.J.H.
Examination of the type specimens of Callichthys splendens Castelnau, 1855, Brochis coeruleus Cope, 1872 (type species of Brochis Cope, 1872), Brochis dipterus Cope, 1872, Corydoras semiscutatus Cope, 1872, Chaenothorax bicarinatus Cope, 1878 (type species of Chaenothorax Cope, 1878), and Chaenothorax eigenmanni Ellis, 1913, has demonstrated that they represent only one species: Brochis splendens. Callichthys taiosh Castelnau, 1855, also has to be considered a synonym of Brochis splendens. Chaenothorax multiradiatus Orcés-Villagomez, 1960, is a second species belonging to the genus Brochis.

Serpulinae (Polychaeta) from the Caribbean: I – The genus Spirobranchus
Provedor de dados: 16
Autores: Hove, H.A. ten.
After studying more than thousand Spirobranchus worms from Curaçao and other Caribbean Islands, and after comparison with the material from other tropical and subtropical regions, it appeared that in the West Indies 3 species and 1 variety of Spirobranchus could be recognized; viz: Sp. giganteus giganteus: large (45—66 mm), more or less solitary; operculum with 2 or 3 antler-like horns; branchiae in a spiral. Sp. tetraceros: smaller (30—40 mm), more or less gregarious; operculum as a rule with 3 groups of much branched horns, appearing as 6 or 8 distinct horns; branchiae not in a spiral. Sp. polycerus: small (about 15 mm), usually forming colonies; operculum in general with 7 small horns, sometimes small secondary spines; branchiae in a spiral. Sp....

Autores: Mees, G.F.
In October and November 1964, after attending the Second Pan African Ornithological Congress at Pietermaritzburg, Natal, I spent some six weeks at Rhodes Inyanga Orchards in the Inyanga National Park, Rhodesia, at the kind invitation of Mr. and Mrs. C. B. Payne. During my stay I observed and collected birds in the Park and its immediate surroundings. In this paper the ornithological results of my stay are recorded. A collecting permit had been obtained for me in advance by Mrs. Payne, and by kind permission of the Chief Warden I was allowed to collect in the National Park. Authorities of the Umtali Museum placed a shotgun and dustshot at my disposal. Mrs. Payne was greatly interested in my activities; she also presented to me several bird-skins, including...

For practical reasons, some of the results obtained from a systematic revision of the genus Bolbitis (including the species formerly referred to Egenolfia) are published prior to an extensive account on all the species and including full synonymy. The few synonyms added to the taxa listed below generally refer to names nowadays in general use. The types mentioned have been studied. The herbarium abbreviations are those proposed by Lanjouw and Stafleu (1964). I am grateful to Dr. R. C. Bakhuizen van den Brink for the Latin translations of the diagnoses of the new taxa.

Problems in the recognition of plant communities in pollen diagrams

Autores: Janssen, C.R.
In recent years pollen analysis has turned increasingly from historical plant geography towards paleoecology. More and more the main interest lies in a reconstruction of the past vegetation instead of simply floristics of a region. Vegetation as a rule is made up of communities¹) that can be described quantitatively in terms of species composition or qualitatively in terms of structure.

Petrology of a part of the western Galician basement between the Rio Jallas and the Ria de Arosa (NW Spain) with emphasis on zircon investigations
Provedor de dados: 16
Autores: Arps, C.E.S.
The present area covers a part of the axial zone of the Hesperian Massif. Rocks of metamorphic and intrusive origin occur in three structural units: the central zone (which in fact forms part of what is called the “blastomylonitic graben”), the migmatic complex and the rocks in the S and SW. During the Hercynian orogeny these units were placed in juxtaposition. With respect to their age and composition the rocks can be subdivided into pre-Hercynian metasediments, metabasic rocks and orthogneisses, and Hercynian migmatites, palingenic granites and intrusive granodiorites, granites, pegmatites, aplites, quartz veins, granite porphyries, lamprophyres and olivine dolerites. Based on penological evidence, the geological history can be reconstructed as follows:...

The use of a precipitin test to determine host preferences of the vampire bats, Desmodus rotundus and Diaemus youngi
Provedor de dados: 16
Autores: Greenhall, Arthur M.
Vampire bat rabies is one of the greatest deterrants to the raising of livestock in Latin America. To know more of the epizootiology of the disease as well as to understand the ecology of the vampire bat family, Desmodontidae, detailed information about their feeding habits and host preferences is essential. Vampire bats feed exclusively on blood. Examination of probable host animals for bat bites has been the primary method used to determine their victims. More reliable precise data are achieved by serological analyses of the digestive tract contents of vampires killed after attacking their hosts. Precipitin test techniques were used similar to those devised for the identification of blood meals of bloodsucking arthropods (Weitz, 1952, 1956, 1960;...

Distance perception by echolocation: the nature of echo signal-processing in the bat
Provedor de dados: 16
Autores: Simmons, James A.
Bats orient themselves in the environment by emitting ultrasonic cries and detecting echoes of these cries that are reflected from near-by objects. 4) One of the many intriguing questions about echolocation, this active sonar sense used by bats, is whether it can serve for the perception of depth or differences in the distance to targets. Bats must often face situations which involve multiple targets; for example, a cluster of several flying insects or an insect flying near branches. It would be of obvious value to the bat in detecting and identifying objects if its sonar could distinguish among such multiple targets. Depth perception is of theoretical interest to us because we might be able to determine something about how the bat processes echoes if we...

A Middle Devonian atrypid brachiopod fauna from the Cantabrian Mountains, northwestern Spain, and its stratigraphic significance
Provedor de dados: 16
Autores: Struve, W.; Mohanti, M.
This paper records for the first time a rich atrypid brachiopod fauna from the Middle Devonian of the Cantabrian Mountains, Spain. A comparison of the Spanish atrypid fauna with that of Germany reveals a close similarity between the two. Even though the species are not identical, yet a comparison and stratigraphic evaluation has been made on the basis of external shape of the shells, ornamentation, etc. It is believed that the development of the Spanish species has been endemic or that the Spanish Middle Devonian sea was supplied with species immigrating from some place other than central Europe. On the basis of the distinct recession of Atrypa and the first appearance of the coarse ribbed species of Spinatrypa (Spinatrypa) a tentative Eifelian/Givetian...

Autores: Sleumer, H.
In 1948, W. B. R. Oliver described the new monotypic genus Plectomirtha, collected by G. T. S. Baylis in 1945 from a single tree on a small rocky islet of the Three King’s Islands off New Zealand. He placed it in the Anacardiaceae, a family hitherto absent from New Zealand. This aroused a certain curiosity both from a taxonomic and plantgeographic point of view, because it would be much intriguing if an endemic genus occurred there. This was the reason why Dr C. G. G. J. van Steenis asked Prof. G. T. S. Baylis from the University of Otago, Dunedin, N.Z., for original material to be able to elucidate this case. A fragment of the holotype, consisting of a few flowers and a leaf, conserved in the Auckland Institute and Museum, became available to our...

Cladobotryum-Konidienformen von Hypomyces-Arten
Provedor de dados: 16
Autores: Gams, W.; Hoozemans, A.C.M.
The genus Cladobotryum Nees is characterized by mostly verticillately branched conidiophores with phialides, dry, one-celled or pluricellular conidia in heads or irregular chains, and pluricellular chlamydospores or sclerotia. Eight species are considered. In four of them the corresponding Hypomyces state is known, in one species it is conjectured. In cultures of Hypomyces rosellus and H. odoratus perithecia were obtained after mating of compatible strains. The conidium-forming cells are interpreted as phialides in all species, even if the meristematic zone extends beyond the apex and surrounds itself with a secondary wall.

A macroscopical description is given of the delivered placenta and foetal membranes of an Aardvark. Special attention is paid to the umbilical cord and the relative position of the foetal membranes at the places where these attach to the placenta. Amniotic pustules were found on the umbilical cord and on the antimesometrial side of the amnion. Many dark-coloured spots were found on the villous part of the placenta. A histological investigation was made of the umbilical cord and the amniotic pustules. Groups of longitudinally arranged smooth muscle cells in that part of the umbilical cord that had been closest to the foetus, suggested the presence of a musculus sphincter umbilicalis. The amniotic pustule on the antimesometrial side of the amnion contained...

Remarks on the thermopreferendum of palearctic bats in their natural habitats
Provedor de dados: 16
Autores: Gaisler, Jiří.
This contribution comprises two remarks of ecological rather than physiological character. Contrary to Herter (1952), Herreid (1967), and Harmata (1969), I did not examine the temperature preference, or thermopreferendum, of bats under experimental conditions but concluded on it only on grounds of temperatures registered in various natural habitats of the bats. Thus, my observations pertain to the thermopreferendum of the resting bats, either inactive or active metabolically. My first remark concerns the temperatures preferred in winter. Hibernating bats are known to differ as to their requirements for ambient temperatures in their winter quarters, as pointed out, e.g., by Dulić (1958) and by many other authors. This phenomenon can be illustrated by fig....

Neurophysiological investigations in the colliculus inferior of Rhinolophus ferrumequinum
Provedor de dados: 16
Autores: Neuweiler, Gerhard.
The horseshoe-bat Rhinolophus ferrumequinum is the best known representative of those bats using constant frequency sounds for echolocation. Schnitzler (1968) has shown, that horseshoe-bats compensate Dopplershifts during flight by lowering the emitted constant frequency so that the heard echofrequency always remains at about 83.4 kHz. His results suggest that horseshoe-bats use the constant frequency part of their orientation sounds for detection and measuring of flight velocities by means of Doppler shifts. The investigation reported here intends to give some clues how constant frequency echoes are processed in the main auditory centre, the colliculus inferior, and how Rhinolophus extracts information for orientation from these echo signals.

Provedor de dados: 16
Autores: Hanák, Vladimír; Gaisler, Jiří.
Czechoslovakia, fortunately enough, belongs to the regions having still numerous habitats resembling the original ones, or at least suitable to the needs of many original species of mammals. This concerns especially the bats while these animals are partly adapted to a synanthropic way of life in a country with many old buildings, parks, woods of different types, etc. Therefore, the protection of bats in Czechoslovakia appears not to be such a serious problem as in some other central and western European countries. Apart from the region of the South Slovakian Kars, we have no data on the decline of bat populations as a whole. Considering this, we were interested in the influence of our own activities on the populations in certain localities. This activity...

Hovering flight of Plecotus auritus Linnaeus
Provedor de dados: 16
Autores: Norberg, Ulla Maria.
The long-eared bat, Plecotus auritus, often flies about in the crowns of trees hunting insects among the branches. It is very clever in manoeuvering in narrow spaces and hovers easily. It can lift off vertically from the ground, and can move vertically up and down. The purpose of this investigation is to show the principles of the hovering flight; to give a description of the wing-beat cycle and a brief account of the flight mechanics. Hovering in Plecotus auritus is earlier described by Eisentraut (1936).

Vampire bat control in Mexico
Provedor de dados: 16
Autores: Schmidt, U.; Greenhall, A.M.; Lopez-Forment, W.
Though usually beneficial, bats sometimes are a nuisance to humans (Greenhall &amp; Stell, 1960), or may even constitute serious economic problems and health hazards. Most important in this respect are the vampire bats, especially of the genus Desmodus, which are abundant from northern Argentina through the whole of Latin America to the north of Mexico. The agricultural problem is caused on the one hand by weakening of the cattle through loss of blood, making them more susceptible to diseases and parasite infestation, as well as by transmitting paralytic rabies (Derriengue). An organized control of vampires has only been established in Trinidad (Greenhall, 1958). On the American continent some control efforts were undertaken sporadically by local...

Autores: Nijssen, H.
During recent expeditions to Surinam, large ichthyological collections have been made from nearly all river systems by several ichthyologists, one of which was the author. Because of new information provided by the especially rich collections of Corydoras, a revision of the Surinam species and subspecies of this genus was thought necessary. This revision is based on 5211 specimens belonging to seventeen species and subspecies of which seven are new to science, viz., C. bondi coppenamensis, C. guianensis, C. heteromorphus, C. octocirrus, C. oelemariensis, C. schwartzi surinamensis and C. saramaccensis.

Autores: Steenis, C.G.G.J. van.
As explained in Takhtajan’s preface this book is not a mere translation of his ‘The origin of Angiospermous plants’ (1961, in Russian), but an entirely new book. I find this true and not true. Comparing it with the Origin (1958 translation of the 1954 Russian version) the essence of the new book was there given in a nutshell. In size, chapter subjects, argumentation, and bibliographic documentation, the work is very much extended and it makes very interesting reading indeed. The sequence of the chapters is logical, almost always leading to distinct synthesis. Properly it is a critical commented survey of many opinions — Takhtajan being clearly in complete command of the huge literature on the subject — but from which the author follows his own line of...

According to the literature, the genus Spadella Langerhans includes several species, Sp. cephaloptera (Busch) 1851, Sp. schizoptera Conant 1895, Sp. moretonensis Johnston &amp; Taylor 1919, Sp. sheardi Mawson 1944, Sp. johnstoni Mawson 1944, Sp. angulata Tokioka 1951, Sp. nana Owre 1963, Sp. pulchella Owre 1963. This genus apparently includes species having world wide distributions, and species with distribution restricted to small regions. At times, several species have been reported from the same geographical region. For instance, MAWSON (1944) observed Sp. cephaloptera, Sp. sheardi, and Sp. johnstoni off the coasts of New South Wales (from off Post Heaking to off Ulladulla). OWRE (1963) observed Sp. schizoptera and Sp. nana at Soldier Key (Florida), and...

On some birds from southern Mexico

Autores: Mees, G.F.
In the years 1962/64 our museum purchased from Mr. Otto Epping, now of Pittsburgh, U.S.A., a collection of 700 bird-specimens from southern Mexico (mainly from Vera Cruz and Oaxaca, a few specimens from Puebla). As our museum was poorly provided with material from Mexico, this was a very welcome addition to our collections. Mexico being now ornithologically well-known, there would be little point in giving a complete list of the species received, but there are a few rare and little-known species included and some others are of faunistic interest as they extend the ranges as hitherto known of the species or subspecies they belong to. In the present paper, the species which for the reasons given above appear to be of interest are listed, and when the...

A comparative study of Plecotus auritus and P. austriacus (Chiroptera, Vespertilionidae) inhabiting one roost
Provedor de dados: 16
Autores: Stebbings, R.E.
This study began in November, 1960 and involved studies of all bats living within one large and complex roof. Furzebrook House, built in 1885, was of brick with hollow walls and a black slate roof. The roof consisted of 9 distinct sections comprising some 385 m³ of which 60 % was accessible for searching. Eight species were caught in these accessible regions and because Plecotus spp. were the most numerous, they became the chief study. The study became more significant when Plecotus austriacus (Fischer) (first described by Bauer, 1960), was identified in the roof. Detailed descriptions of the two English Plecotus have already been published (cf. Stebbings, 1967). The aim of this report is to present evidence that might suggest reasons for the distribution...

The distribution of bats on the Adriatic islands
Provedor de dados: 16
Autores: Dulić, Beatrica; Tvrtković, Nikola.
The bat fauna of the Adriatic islands is very poorly known in comparison with that of the coastal continental regions (Kolombatović, 1882, 1884; Dulić, 1959). Although ten species of bats are recorded, the data for most of the islands except the island of Lastovo (Dulić, 1968) are scarce, and of an early date. During the years 1966—1970, mostly in the summer (July, August), we investigated the bat fauna of some Adriatic islands, particularly of the southern ones. During 17 trips, each of 5 to 10 days, to 8 islands, 200 bats were collected and several hundreds were examined (caught in mist nets or taken in caves). The investigated area is shown in fig. 1, the distribution of the bats in table I. Bibliographical data included, 16 species of bats from the...

Knowledge of the avifauna of Formosa or Taiwan has been summarised excellently by Hachisuka &amp; Udagawa (1950, 1951), who included references to many publications by Japanese authors, not readily available in Europe. As far as published evidence goes, not much ornithological work has been done in Formosa since 1951 : I have found only a few more recent papers, each dealing with a single species (Deignan, 1958, 1964; Ripley, 1962; Wayre, 1968).

Provedor de dados: 16
Autores: Gillison, A.N.
A comprehensive study of structure and floristics in a typical montane (2700 m) grassland/forest transition in Papua-New Guinea was made using a destructive technique involving complete removal of all woody species below 10 m, in a single belt transect. By this means the distribution of all tracheophytes in a dense transitional system was accurately determined, providing evidence that the transition was advancing over open grassland. Use is made of profile and plan drawings. The transition is described as a discrete community in terms of juvenile, mature, and senescent phases. A distinct group of transition species is recognized. The distributions of life-forms and a symbiotic relationship between moss-hummocks and transition species are discussed, and the...

Biosystematic notes on Atriplex patula L., A. hastata L., and A. littoralis L. (Chenopodiaceae)
Provedor de dados: 16
Autores: Meijden, R. van der.
In about 10—15 % of the cases a sharp distinction between Atriplex hastata L., patula L., littoralis L., and glabriuscula Edm. is not possible, both in the field and in the herbarium. In order to establish the status of the ‘intermediates’ a karyological examination was undertaken of 95 samples collected in the Netherlands including both typical specimens and intermediates. It appeared that the specimens clearly representing A. hastata, littoralis, or glabriuscula are diploid (n = 9), but those representing A. patula tetraploid (n = 18). The ‘intermediates’ between A. hastata and patula are either diploid or tetraploid. Hence a sharp distinction between the latter two taxa is only possible on the chromosome number. A similar result was found for the...

This is primarily a textbook for students, providing a synopsis of orders and families of Gymnosperms, Dicotyledons, and Monocotyledons native, naturalized, and commonly cultivated in Malaya and Singapore. It emerged from a syllabus prepared by the author in 1960. There is a brief introduction. The bulk of the work is taken up by the descriptions of orders and families, each provided with a succinct discussion. Of most families one species is figured, the figure consisting of a habit drawing with a diagram and flower analysis: obviously almost all are original. There is a key to the orders, within each order a key to the families, and appendix 2 gives a simple artificial key to the common families.

The aural anatomy of bats
Provedor de dados: 16
Autores: Pye, Ade.
The fine structure of the ears of 62 species of bats from 13 families has been studied by means of serial sections. The bats were caught alive in Britain, West Indies, Panama, Central and North Africa and were intra-vitally perfused with fixative in order to obtain perfect preservation of the internal ear. Where possible, up to six specimens of each species were fixed for this study and all the ears were sectioned in the horizontal plane. This paper will survey briefly some of the results obtained. The pinnae of bats are varied in size, shape and structure and have not been studied in detail. In many bats, e.g. Rhinolophus and Hipposideros they are mobile, the movements being correlated with pulse emission (Pye, Flinn &amp; Pye, 1962; Pye &amp; Roberts,...

Relations pondérales entre l’encéphale et le corps chez les chiroptères. II. Espèces paléo-tropicales et paléarctiques. Discussion et conclusions
Provedor de dados: 16
Autores: Pirlot, Paul.
The ratio brain weight/body weight is studied in 30 species of bats from Asia, Africa and Europe, in comparison with 20 other species from South America dealt with in a previous paper. The simple encephalic ratios, expressed in o/oo, vary considerably and about between the same limits on the four continents. Further, logarithmic regression lines (brain to body), when fitted to the representatives of various dietary types, provide slope and ordinate values that are visually distinguishable. Besides, the encephalic ratios themselves show, among bats, a negative correlation with the abolute somatic weight, as one might have expected. But, if one compares graphically, from that viewpoint, the Chiroptera on the one hand with a number of Insectivores and...

Autores: Kliphuis, E.
The three species Galium silvaticum L., Galium aristatum L. and Galium schultesii Vest show differences in morphology, cytology and geographical distribution. These differences are described and discussed. Crossing experiments between the three species were without results. No hybrid could be obtained. Galium silvaticum, Galium aristatum and Galium schultesii must be considered as separate species.

Three Bathyal Prosobranchs (Gastropoda) from the Southeast Asian Waters
Provedor de dados: 16
Autores: Knudsen, J.
The present report is based on three specimens of Prosobranchs from the southeast Asian waters. Two appear to represent each a species new to science, while the third specimen is assigned here with some doubt to a previously known species. One sample was collected by the Naval officer Land, and two samples were procured by Dr. J. Verwey during his participation in the "Java-South Africa Expedition 1929-30" organized by Dr. Th. Mortensen, Copenhagen. The material is kept in the Rijksmuseum van Natuurlijke Historie, Leiden, the Netherlands. I am greatly indebted to Dr. C.

Naar aanleiding van het artikel over Cochlearia pyrenaica DC. (in Gorteria 4(11), 1969, p. 187—188) ontving de redactie de volgende mededeling: Ik werd op het Lontzenerbachdal attent gemaakt door de heer Houtman, die in Enschede een dia-lezing hield en daarbij enthousiast vertelde over deze „botanische schatkamer”. Met Pasen 1968 was ik in Zuid-Limburg en ging natuurlijk even kijken. De Lathraea en de Helleborus die hij vermeldde vond ik niet, wel een prachtige voorjaarsflora zoals op de mooiste plekken van Zuid-Limburg met als „extra’s” veel Narcissus pseudonarcissus en tot mijn verbazing een Cochlearia, die C. pyrenaica bleek te zijn.

Geology of the Upper Segre and Valira valleys, Central Pyrenees, Andorra/Spain
Provedor de dados: 16
Autores: Hartevelt, J.J.A.
Sheet 10 of the 1:50,000 geological map series of the Geological Institute, Leiden University, is presented accompanied by a survey of structural, stratigraphic and morphologic features. The region includes part of the southern Axial Zone, the eastern end of the Nogueras Zone and part of the marginal trough adjacent to the south. Formations mapped range in age from Cambro-Ordovician to Pliocene. Detailed lithostratigraphic studies of the Cambro-Ordovician and Devonian rocks enabled correlations to be made with other regions of the Pyrenees. The Hercynian orogeny formed structures of variable shapes and orientation, which, however, have all be ascribed to stress accumulating in a N-S direction causing consecutive deformations. These can, to a certain...

Pendant une mission d’étude de l’Université d’Amsterdam sur le comportement des chimpanzés à l’état sauvage (République de Guinée, province de Kindia) les auteurs se sont intéressés également aux relations entre ces anthropoïdes et les êtres humains. La population humaine se montre très tolérante et plutôt indifférente envers les chimpanzés malgré que ces derniers peuvent faire des dégats à leurs produits agricoles. De ce point de vue l’avenir des chimpanzés est assuré dans cette province de la République de Guinée à la condition que les autres facteurs qui peuvent nuire à la presence de chimpanzés ne changeraient pas.

The present study deals with the primary lithology, sedimentary structures, depositional history and paleogeography of an Upper Cretaceous turbidite basin in the south-central Pyrenees, and presents a brief review of the lithology and depositional environment of surrounding contemporaneous deposits. During Coniacian to lower Maastrichtian, over a longitudinal distance of about 80 km along the present strike of the Pyrenees, thick series of calcareous turbidites, pebbly mudflows, slumps, sedimentary limestone breccias and marls accumulated, constituting what is termed the Vallcarga Formation.

Pollen morphology of the genus Lepisanthes (Sapindaceae) in relation to its taxonomy
Provedor de dados: 16
Autores: Muller, Jan.
The pollen morphology of 18 out of 22 species of the genus Lepisanthes, as recently revised, was studied. General pollen morphology is rather uniform, but taxonomically significant differences exist in shape, relative length of ektoapertures, endoaperture development, and in the sculpture of the tectum. Detailed descriptions are presented and special attention is given to intraspecific variability. 10 Pollen types are recognized, most of which are linked by transitions. Morphological trends are established and the extent to which they indicate natural relationships is evaluated. In subgenera Lepisanthes and Erioglossum a less evolved but more variable pollen morphology is present, while in subgenera Otophora and Aphania derived pollen types occur, which...

Those findings were in agreement with previous information by Topál (1958) pointing out differences in the morphology of the baculum in Hungarian populations of that species, and even considering the differences between the two forms of specific value. The present paper is a summary of new discoveries concerning this problem; the characters distinguishing the two forms are discussed, whereas new information on their distribution in Central Europe is presented, and their systematic position is evaluated.

De dotterbloem in Nederland
Provedor de dados: 16
Autores: Smit, Petra G.
515 specimens of the polymorphic species Caltha palustris from 55 Dutch localities were studied morphologically and cytologically. Two cytotypes could be distinguished, a cytotype with 32 chromosomes and another with 56 chromosomes. These two cytotypes have slight morphological differences and different ecological preferences which although incompatible in crosses are insufficient for distinguishing separate species or even subspecies. The studies lead us to the conclusion that Caltha palustris is a species with large genecological differentiation in its populations. The intraspecific polyploidy, which could have arisen by mutations, will have enhanced the polymorphism of the species, resulting in series of more or less discontinuous ecotypes with...

Enige opmerkingen over het geslacht Pulegium
Provedor de dados: 16
Autores: Adema, F.
The author treats Pulegium Mill, as a good genus. For the separation of Pulegium from Mentha, he uses, besides the well-known differences in calyx and corolla, a new character, namely that the anterior stamens are curved towards the upper lip and, together with the posterior ones, ascend under this lip, whereas in Mentha all stamens are straight and diverge from their base. On the ground of this character, already used by BRIQUET (1897, p. 208) as being of primary importance Pulegium is related more to genera as Satureja, Micromeria, Melissa, etc., than to Mentha s.s. The genus Pulegium contains 2 or 3 species, the wide-spread P. vulgare Mill., the Corsican P. parviflorum (Req.) G. Sampaio, and perhaps also the Algerian Mentha gattefossei Maire.

Pacific capsular Myrtaceae 1. Reproductive morphology of Arillastrum gummiferum Panch. ex Baillon (New Caledonia)
Provedor de dados: 16
Autores: Dawson, J.W.
Niedenzu (in E. &amp; P., Nat. Pfl. Fam. 3, 7, 1893, 87—89) included the following genera in his subtribe Metrosiderinae: Metrosideros, Spermolepis2 (= Arillastrum), Cloëzia, Lysicarpus, Tepualia, Syncarpia, Xanthostemon, Pleurocalyptus, and Tristania. The Metrosiderinae was distinguished from the Leptosperminae by usually having flowers in axillary groups, not solitary, and from the Eucalyptinae by having narrow, not broad based petals. A preliminary survey of the above genera indicates that Niedenzu’s subtribe Metrosiderinae is not a natural group and in this paper, the first of a series, a critical examination of reproductive features of Arillastrum Panch. ex Baillon leads to the conclusion that this genus, notwithstanding its narrow petal bases, is...

Ecology and morphological characters of different populations of Poecilia sphenops vandepolli (Cyprinidontidae)

Autores: Feltkamp, Constance A.; Kristensen, Ingvar.
In the Netherlands Antilles, opposite the Venezuelan coast, the cyprinodont fish Poecilia sphenops vandepolli is found in fresh water, in brackish water, in the sea and in supersaline water. When comparing the populations from fresh water, sea water and supersaline water some significant morphological differences were found, e.g. in size, in depth of the body and of the caudal peduncle, in length of the head, and in the number of rays in the pectoral and caudal fins and the number of lateral scales. In raising experiments, however, it could be shown that these differences are phenotypic. The characteristics of the subspecies or varietas arubensis as described by VAN LIDTH DE JEUDE (1887) proved also to be phenotypic. Optimum growth was found in seawater....

Referring to a recent paper in „Gorteria” (JACOBS, 1969) attention is drawn to the importance and possibility of systematic phenological observations as a routine aspect of vegetation studies. Some references are made to the treatment of this problem in phytosociological literature. Proposals are made for simple standard scales for the estimation of degrees of vegetative growth, flowering and fruiting and their characteristic stages during the various seasons. These scales are derived from, but not identical to the scales proposed earlier by the author and some of his collegues (see references). The importance of a sharp distinction between the three aspects of plant life mentioned is emphasized.

The Lesser Antilles, extending some 500 miles from Anguilla on the north to Grenada on the south, form an archipelago connecting the Greater Antilles with Trinidad and the South American mainland.¹) Bats comprise the major segment of the extant mammalian fauna of the Lesser Antillean islands and the distribution and variation of chiropterans in this area long has interested systematists and zoogeographers. A revival of this interest in the past decade has resulted in a number of published contributions — KOOPMAN (1958, 1959, 1968), HUSSON (1960), DE LA TORRE (1966), DE LA TORRE &amp; SCHWARTZ (1966), JONES &amp; SCHWARTZ (1967), SCHWARTZ &amp; JONES (1967).

Therefore, here an attempt is made to trace Seba's specimens through history, and to indicate where those examples still extant should be looked for at the present time. As Seba's cabinet was auctioned at a time when "Holland" was exceedingly rich in such collections, almost each of them at the death of its owner...

Two new species of Hydrodessus from Suriname, with a key to the known species (Coleoptera: Dytiscidae)
Provedor de dados: 16
Autores: Young, Frank N.
The genus Hydrodessus is readily distinguished, from the other small water beetles related to the Old World Bidessus, by the lack of pronotal or elytral plicae, by the structure of the hind coxal processes, and by the simple, unjointed parameres of the male genitalia (Balfour-Browne, 1953). The species are very rare in collections, and several are still known from only the unique types. The genus Brinkius (Guignot, 1957) differs from Hydrodessus only in that a fine lateral humeral carina is present on the elytron above the epipleural margin. In all other characters, including the unique parameres of the male genitalia, the two genera seem to be identical, and I therefore apply the older name to both groups. The two new species described below from Suriname...

Wood samples of a number of Cinchoneae and Naucleeae sensu Schumann were studied, and the results compared with data found in the literature. On the whole the representatives of the Cinchoneae appeared to show a rather high degree of similarity among each other with the exception, however, of the genera Coutarea, Exostemma, Corynanthe, Crossopteryx, and Hymenodictyon. The creation of the tribe Coptosapelteae and its inclusion in the Ixoroideae seem to be corroborated by the particular character of the wood anatomy. The restriction of the Naucleeae to Nauclea L. ( Sarcocephalus Afzel.) is not supported by the anatomy of the wood.

The genus Cladobotryum Nees is characterized by mostly verticillately branched conidiophores with phialides, dry, one-celled or pluricellular conidia in heads or irregular chains, and pluricellular chlamydospores or sclerotia. Eight species are considered. In four of them the corresponding Hypomyces state is known, in one species it is conjectured. In cultures of Hypomyces rosellus and H. odoratus perithecia were obtained after mating of compatible strains. The conidium-forming cells are interpreted as phialides in all species, even if the meristematic zone extends beyond the apex and surrounds itself with a secondary wall.

Electronic aids to the identification of bats in flight and to their study under natural conditions

Autores: Watson, Andrew.
Positive identification of bats usually requires visual inspection at close range or for a bat to be held in the hand. There are many people, particularly conservationists, who would like to study bats in their natural environment without disturbing them. The task of preparing distribution maps is at present a slow and painstaking task, depending on the limited number of observers who can accurately identify bats. Most bats emerge at dusk and although some can be seen in such poor lighting conditions, most bats flying at night cannot be observed when below the horizon and against a dark background.

In the past decade there has been an increasing awareness that spontaneous activity in hibernating mammals is not a mere accidental imperfection in the mechanism of hibernation but, on the contrary, a regular and important feature of it. Several recent investigations (e.g. Kristofferson &amp; Soivio, 1967; Pohl, 1967) have dealt with activity of mammals hibernating under laboratory conditions. Comparatively little is known of activity patterns during the hibernation season in natural circumstances.

The problem of European freshwater populations of Gammarus duebeni Liljeborg, 1852
Provedor de dados: 16
Autores: Pinkster, S.; Dennert, A.L.; Stock, B.; Stock, J.H.
In addition to the well-known freshwater occurrence of Gammarus duebeni in the inland of Ireland, a similar inland occurrence in the western part of Brittany (= Bretagne, France) is demonstrated. In Brittany, as in Ireland, G. duebeni occurs in waters with low sodium concentrations (often less than 23 mg/l), whereas elsewhere in its range, G. duebeni lives in waters with a raised sodium content (either in mixohaline waters, or in “fresh” waters loaded with salts through gales from sea). Reid has proposed the designation G. duebeni α for the Irish freshwater form, G. duebeni ß for the brackish water form. The subdivision of G. duebeni is strongly reinforced by the findings of Sutcliffe et al., indicating physiological differences between the α and ß form....

The Lindsaeoid ferns of the Old World V. The smaller Pacific islands
Provedor de dados: 16
Autores: Kramer, K.U.
The present paper is the third regional revision of the Old World Lindsaeoid ferns. The second (the fourth in the entire series on the Old World Lindsaeoids) will be published as vol. II, 1 part 3 of Flora Malesiana; it is awaiting publication as the present paper goes to the press. Species fully described there and extending into the area covered by the present revision are not dealt with at length again, in order to avoid redundance. The present treatment deals with the species of Micronesia, Melanesia, and Polynesia, or, more precisely, the smaller Pacific Islands from the Palau Islands, the Marianas, and the Bismarck Archipelago in the West to Hawaii and the Marquesas in the East. The Volcano and Bonin Islands wil be treated with Japan, to which...

Remarks on the thermopreferendum of palearctic bats in their natural habitats
Provedor de dados: 16
Autores: Gaisler, Jiří.
This contribution comprises two remarks of ecological rather than physiological character. Contrary to Herter (1952), Herreid (1967), and Harmata (1969), I did not examine the temperature preference, or thermopreferendum, of bats under experimental conditions but concluded on it only on grounds of temperatures registered in various natural habitats of the bats. Thus, my observations pertain to the thermopreferendum of the resting bats, either inactive or active metabolically. My first remark concerns the temperatures preferred in winter. Hibernating bats are known to differ as to their requirements for ambient temperatures in their winter quarters, as pointed out, e.g., by Dulić (1958) and by many other authors.

The Malesian species of Gastonia (Araliaceae)
Provedor de dados: 16
Autores: Philipson, W.R.
Only two species of Gastonia occur in Malesia, but each has a complex taxonomie history. The species which became known first, G. papuana Miq., is evidently an uncommon plant of coastal and lowland forest, but with a very wide range. It has been collected only once, or at most a few times, from each of many islands of the Malayan Archipelago and once from the mainland of the Peninsula. Most of these collections were made in the nineteenth or early twentieth centuries. Only in western New Guinea has this species been collected in more recent times within our area. The distribution of this species shows several disjunctions, the most striking being that between West Irian and its only known locality in the extreme east of the Solomon Islands. It is...

Phenetic relationships in the genus Myotis
Provedor de dados: 16
Autores: Findley, James S.
The genus Myotis is of interest to the evolutionist because of its diversity and because of its nearly cosmopolitan distribution. An understanding of the biology of this remarkable genus may provide insight into its success, as well as the success of other expansive groups of mammals. As part of an overall study of Myotis, I subjected measurements of 48 morphological traits from most of the described species to standard numerical taxonomic analysis. I hoped to delineate phenetic groupings in the genus, and to learn if these groupings provide insight into adaptive diversification of species, into the history of the genus, and into a replicable approach to its classification. Phenograms based on Pearson product-moment correlation coefficients and on...

Ya hace casi cuatro decenios que penetran permanentemente colonos en el "piedemonte" meridional en la margen oriental de los Andes colombianos. La colonización de vastas regiones cubiertas de selva pluvial es ante todo la obra de pobres colonos espontáneos. El artículo trata de los métodos de la roza y de la cultivación del suelo, de las formas de agricultura, de la estructura de las poblaciones, de la circulación y del comercio en esta zona de colonización. Desde hace pocos años, su poblamiento es promovido efectivamente también por el Instituto Colombiano de la Reforma Agraria (INCORA).

In a previous publication we focussed on the description and the study of the zonation of the organisms and their living conditions on a wave-breaker in Knokke.  We showed that a certain number of dominant species are situated at exact levels of the wave-breaker, levels that we designated under the name of stages: 1. Algae stage2. Barnacle stage3. Mussel stage4. Tubularia stageEach of these stages is subdivided in characterised zones by particular associations of organisms. We described these organisms in the first part. We are interested in the second report to define the role of each of the partners of an association, emphasizing the biology and the ecology and the interaction between the different species.

The worm &lt;i&gt;Polydora ciliata&lt;/i&gt; is colonized, at the Belgian coast, by 2 amphipods: &lt;i&gt;Jassa falcata&lt;/i&gt; in the surf zone and &lt;i&gt;Corophium insidiosum&lt;/i&gt; in calm waters. This difference is caused essentially by the morphological characteristics of the 2 amphipodes: &lt;i&gt;Jassa falcata&lt;/i&gt; possesses a pair of very strong gnathopodes II, allowing it to hold on firmly in strong currents, while &lt;i&gt;Corophium insidiosum&lt;/i&gt; lacks these characteristics.

FUTURE AUSTRALIA-JAPAN TRADE RELATIONS
Provedor de dados: 31
Autores: Bieda,   K.
The leitmotif of this paper is the strong, rising and alarming trend of deficits in Australia's balance of payments current account, which makes it overwhelmingly important to increase exports. Market promotion, substantially the existing method, will not do the job in a world with politically set up trade barriers. Multilateral political negotiations about the removal of the trade barriers within the G.A.T.T. system are unlikely to help for Australia's range of exports. Therefore Australia must enter into bilateral negotiations with any likely important customer, the most obvious one being Japan, to lower trade barriers on a bilateral basis, and this under the existing international agreements can be done only under the guise of a partial free trade area.

CHANGES IN FARM PRODUCTION UNDER INTENSIVE FARM MANAGEMENT ADVICE
Provedor de dados: 31
Autores: Southcombe,   F.J.; Mauldon,   Roger G.
This investigation examines the impact of intensive farm management advice on levels and productivities of resource use on samples of farms. A total of 60 members of 13 farm management advisory services and 60 non-members, matched by locality, were studied in two farming regions of Western Australia. A production model has been formulated and analysed which discriminates between effects of differences and changes in resource use and productivity over time and between members and non-members. Major differences between members and non-members over time have been rates of growth of inputs and outputs rather than systematic changes of production relationships.

ECONOMIC ASPECTS OF FORAGE PRODUCTION AND UTILIZATION ON IRISH FARMS WITH SPECIAL EMPHASIS ON BEEF PRODUCTION
Provedor de dados: 31
Autores: Connolly,   John Augustine.
At present Ireland is a keen applicant for admission into the European Economic community.  Sheehy has stated that if Ireland becomes a full member of this community it will have a comparative advantage in the production of grass products. This will be particularly true in the case of beef production.  With this in mind the main objective of this research paper was to introduce how the grass crop has fitted into the Irish farming scene up to now and what recommendations should be made in order to maximize net returns from this forage crop in the future.

The objective of this study is to define in the cost minimizing sense the optimum size and location for beef slaughter plants in the Eastern Central Queensland region. The plant location model used for this purpose is a modified transhipment formulation. It is applied to both a long run unlimited capacity case and a short run limited capacity case. The analysis indicates that for both cases production-area oriented slaughter minimizes costs. Sensitivity testing of the stability of the solution is outlined.

The genetic changes which would occur in overseas flocks as a result of the export of merino rams from Australia are unknown. Even so, Australia recently relaxed the merino export embargo and may go further. A comparative static model is presented to assess changes in annual wool income resulting from increases in the supply of apparel wool emanating from possible levels of the genetic effect.

ELASTICITY OF SUPPLY AND THE INCENTIVE FOR COLLUSIVE BUYING
Provedor de dados: 31
Autores: Piggott,   Roley R.
A model is developed to show how changes in the elasticity of the supply function at the farm level offset increased levels of buyer (processor) concentration such that given percentage increases in demand by large buyers result in the same, or smaller, percentage price changes than do increases in demand on the part of small buyers. Since the incentive for collusive buying is a function of the potential price increases which follow demand increases, there may be little incentive for buyers to collude even if they are highly concentrated.

Provedor de dados: 31
Autores: Lewis,   A.C.
This note is concerned with one aspect of the methodology for examining the gains and losses of a buffer stock scheme for wool.  It is shown that it is incorrect to debit interest due on capital tied up in stocks of wool without, at the same time, crediting a portion of this to the grower.  The errors that can occur in calculations that do not take account of the charged time distribution of growers' receipts are demonstrated.

A number of current policy issues are discussed which illustrate serious confusion and economic illiteracy in the minds of many influential farm leaders. The issues discussed are: the cost-price squeeze in agriculture; the embargo on the export of merino rams; promotion of farm products; land policy; and tax concessions for agriculture. In some cases policies are followed which run counter to both farmer and national interests. Along with farm management extension, there is a growing need for agricultural policy extension.

FARM ADJUSTMENT AND THE ROLE OF GOVERNMENT
Provedor de dados: 31
Autores: Harris,   S.F.
The problem of low income farms in Australia is examined in a dynamic context of overall farm adjustment. It is suggested that the pace of agricultural adjustment has been and is too slow, in the light of current and prospective market and cost trends. Consideration is given to both the case for, and the possibilities of, government action and the relationship of on•-farm adjustment to the adjustment needs of the economic and the social infrastructure on the agricultural sector.

Towards Optimum Fat Lamb Mating Strategies on the Northern Tablelands
Provedor de dados: 31
Autores: Johns,   Murray A.; Pearse,   Robert A.
An attempt was made to quantify some of the variables which affect mating strategies on the Northern Tablelands in the high rainfall zone of New South Wales. A single year linear programming model was developed which permitted the determination of the optimum date of lambing of a Merino X Border Leicester ewe flock (composed of four tooth, six tooth, and full mouth ewes and mated to Dorset Horn rams) for a range of prices and seasonal conditions. It was found first, that generally a staggered lambing is most profitable; secondly, that it pays to lamb early for the Christmas-New Year market if premiums are adequate; and thirdly, that it pays to buy considerable quantities of oaten grain for winter feeding.

RESOURCE ALLOCATION IN TRADITIONAL AGRICULTURE:  A CASE STUDY OF WEST BENGAL IN THE MID-FIFTIES
Provedor de dados: 31
Autores: Rudra,   Sulata.
An era has come when the most ancient industry, namely, agriculture is beginning to be transformed in the underdeveloped countries of the world.  Changes are taking different directions in different places with different rates of growth.  However, the "traditional agriculture" characterized by age old techniques of production is not a myth of the past.  There are vast agricultural areas, where even though modernization has started, the rate of growth of agriculture is not fast enough to wipe away some of the basic characteristics of "traditional agriculture."  The present study is an exploration of resource allocation in traditional agriculture and employs linear programming techniques to answer the following questions:  (1) How far do we find conformity...

EDUCATION AND POVERTY IN MICHIGAN
Provedor de dados: 31
Autores: Jessup,   Gerald O.
In the United States as a whole, 21.4% of the families have incomes below $3,000 while in Michigan, only 15.7% fall below this line.  Poverty in Michigan is definitely not as severe as that which exists in many states of the deep South and in Appalachia.  In Michigan, there are about 314,000 families or 1,256,000 people who have incomes or live in families with incomes below $3,000 per year.  The poor exist in every county of every state.  Poverty for the purposes of discussion was defined as existing when a family of four had an income of $3,000 or less.  Seven hypotheses describing the relationship between lack of resources and poverty were considered.  One of these is the relationship between poor educational systems and low income.  This relationship...

CAPITAL BUDGETING, INTERTEMPORAL PROGRAMMING MODELS, WITH PARTICULAR REFERENCE TO AGRICULTURE
Provedor de dados: 31
Autores: Rae,   Allan N.
Investment decision processes typically involve the selection of projects, the timing of their initiation and the determination of the amount to be invested in each time period. A linear programming model considered appropriate for solving such models is described, in which the multi-dimensional criterion function is expressed as a linear combination of the appropriately-weighted objectives. An empirical application is then discussed, the objectives of the firm being the maximization of tax-free cash and assets on hand at the end of the planning period. Finally, the appropriate length of the planning horizon, and some approaches to capital budgeting under non-certainty, are discussed.

CLASSIFICATION OF INPUT-OUTPUT FACTORS AND CRITICAL PATH SCHEDULING IN PLANNING BEEF PRODUCTION SYSTEMS
Provedor de dados: 31
Autores: Hile,   Thomas A.
The purpose of the paper is to examine the possibilities for using systems analysis concepts in planning and analyzing various sizes and types of beef production units.  There are a number of aspects to be considered in applying systems concepts to beef production systems, and this paper will discuss some of them.  The basis reason for using this approach is to provide farm management with a method for improving a beef production operation where uncertain conditions exist that create problems for the farm manager.  By using systems analysis planning models in a beef production operation, the farm manager may be able to pinpoint problem areas and eliminate or minimize their efforts and decrease the level of uncertainty within certain areas of operation.

SOME MARKETING CONSIDERATIONS FOR THE ANALYSIS OF OPPORTUNITIES TO EXPORT PROCESSED FOOD IN LATIN AMERICA
Provedor de dados: 31
Autores: Torrealba M.,   J. Pablo.
One of the major obstacles to the development of most Latin American countries has been the concentration of exports in a few agricultural commodities which have had unstable prices in world markets.  Furthermore prices for these agricultural products have been declining relative to the prices of the goods imported in this region.  Consequently, there have been sharp fluctuations in the foreign exchange earnings and increasing difficulty in obtaining the imports needed to sustain satisfactory rates of economic development.  Many countries facing this situation are making an effort to diversify their export bases.  One of the possible means of attaining diversification is through the development of an export-oriented food processing industry or sector....

A MODEL FOR THE ECONOMIC EVALUATION OF WATER QUALITY IN IRRIGATION
Provedor de dados: 31
Autores: Yaron,   Dan; Bresler,   E.
A model for determination of the efficient combination of water quantity and quality (salinity) in irrigation is presented. The efficient combination is evaluated with respect to a predetermined threshold salt concentration in the soil solution. A leaching model, designed for tracing salt distribution in the soil profile, serves as the basis for the analysis. The optimal quantity-quality combinations are derived with the aid of a linear programming model. An illustrative application of the model concludes the presentation.

THE POTENTIAL FOR INCREASING AGRICULTURAL TAXES IN EAST PAKISTAN
Provedor de dados: 31
Autores: Rahman,   Muhammad Zillur.
No one tax system is best suited for all countries or even for one country at all points of time.  The tax structure as well as the tax level should change with the structural change in the economy during development.  Otherwise the government expenditure-revenue gap over time may become too wide and result in inflation and political instability.  Agricultural taxes can play an important role in a growing economy.  But in practice we find from different studies that the share of agricultural taxes in government in most of the developing countries is declining.  There is a growing view among economists that agriculture in many of the less developed countries (LDC's) is undertaxed.  If tax policy is not changed it is highly likely that agriculture will not...

Agricultural Flood Damage Assessment: A Review and Investigation of a Simulation Method
Provedor de dados: 31
Autores: McDonald,   G.T.
This paper reviews current methods of estimating agricultural flood damage and proposes a model which is flexible for use in resource allocation problems and is amenable to computer application. The inherent variability of the damage process itself suggests the use of probability measures, and to demonstrate the use of the assessment model, range estimates sampled under rectangular probability assumptions are used to simulate variability. While the problem of unreliable basic data remains, it can be explicitly recognized by variance estimates.

Poplar Growing and Farm Adjustment on the North Coast of New South Wales
Provedor de dados: 31
Autores: Sinden,   Jack A.
The poplar species, Populus deltoides provides types which are ecologically well suited to the rich alluvial soils of the north coast. This study uses a simple simulation model and linear programming to explore the economics of introducing poplars into farm plans on this soil type. If the price of poplar timber does not fall by more than 60 per cent relative to other agricultural prices, and if plantations can be financed at discount rates less than 10 per cent, then poplar growing has considerable scope for integration with other farm activities. Poplars should be included under all the farm conditions tested, namely farm sizes between 100 and 150 acres, labour forces between one and three men per farm and a doubling of dairy profitability over the...

A GRAPHICAL ILLUSTRATION OF THE DULOY PARADOX
Provedor de dados: 31
Autores: Powell,   Alan A.
As a guide to the reorganisation of resources, the MVP /MFC comparison can result in the adjustment of resources to new levels which are actually further away from their optimal levels than their original values. Duloy illustrated this paradox mathematically in the context of fitted agricultural production functions in a paper published in 1959. His result is of considerable importance to agricultural micro-economists; however, it is not easy to teach to students of poor mathematical background. The need to be able to teach in literary form the Duloy Paradox--that increasing the application of a factor with a relatively high MVP can result in a movement away from the optimum input-mix--led to the following analysis.

A computationally efficient method is developed in this paper for deriving a sequence of bounds to the global value of an integer fixed charge problem where certain functions are linear only for positive values of the argument and have a jump discontinuity at the origin. While other efficient approximate techniques are available, the technique developed here offers the additional advantage of permitting the sequential error inherent in approximate solutions to be determined.

In the underdeveloped countries in general, where today about two thirds of the world population live, there is a widespread awareness that their economies are not keeping pace with the more developed nations, a great desire to speed up the growth of the various sectors of the national...

Economic planning is undertaken in the belief that development can be brought about or accelerated by government intervention.  Referring to the countries of South Asia, Myrdal points out that these countries have long remained in a state of relative stagnation, and that "a strong impetus is needed to end such an economic stalemate."   India is the biggest of all the less developed countries with more then 540 million people, most of whom live in desperate economic conditions.  The magnitude of her problems is large, hence there is a need for large-scale economic planning.  For rapid economic growth, however, there is a need for effective planning, which in turn calls for a large-scale mobilization of resources.  The purpose of this paper is to examine the...

A Case Study of Spatial Diversification of Pastoral Sheep Holdings
Provedor de dados: 31
Autores: Anderson,   Jock R.
Those familiar with the extensive wool growing industry of Australia generally recognize the importance of spatial diversification of pastoral sheep holdings but to this time, data have not been assembled to quantify this importance. This case study based on the sheep and wool industry of central western Queensland goes some way towards filling this gap in knowledge by detailing the extent and nature of spatial diversification of multiple holdings in a survey of 145 sheep holdings.

A Spatial Analysis Approach to Size and Location of Australian Wool Selling Centres
Provedor de dados: 31
Autores: Ferguson,   D.C.; McCarthy,   W.O.
This study is concerned with determining the number, size, and location of selling centres for Australian wool so that transport and selling charges are minimized. A plant location model incorporating transhipment assumptions was used. It was found that substantial cost savings could be made by rationalizing wool flows and establishing integrated selling centres. Of fourteen existing centres five were eliminated, and relative throughput at the remainder changed markedly.

This Technical Note provides a guide for rounding numbers used in the agreement, narrative and tables of Watershed Work Plans and River Basin Reports. Rounded numbers improve appearance and creditability, and reduces errors and conflicts. Ideas presented herein and in the attachments can serve as a guide. However, they will not rule out the necessity for prudent judgment in each case. Therefore, in review of the examples attached, recognize that rodding of values for a particular Watershed Work Plan must be tailored for that particular plan.

PRICE RESPONSE OF NIGERIAN PALM PRODUCTS
Provedor de dados: 31
Autores: Teigen,   Lloyd D.
The oil palm has been the most important of the three major cash crops in the southern region of Nigeria.  During the period 1955-1964, exports of palm kernels and palm oil averaged over   33 million per year, about 21 percent of the value of Nigerian exports in this period.  This compares with the value of cocoa exports of about   32 million and the value of exported rubber of about  10 million.  The other major agricultural export is groundnuts (peanuts), grown in the North, which averaged   28 million in exports.  During this approximately same period the marketing boards, the sole buyers of exported palm products, performed primarily the fiscal role of assembling funds to support development programs.  With the introduction of new information on the...

FARM MANAGEMENT EDUCATIONAL PROGRAM IN THE U.S. AND THAILAND
Provedor de dados: 31
Autores: Saiprasert,   Prayong.
In the early agricultural period in the United States, land and labor represented about 85 percent of all resources used, farms tended to be small, farmers had limited skill and experience in managing their farms.  Each farmer produced food for himself and his family.  Capital inputs represented about 15 percent of the total.  About 5 decades ago a big change began in U.S. agriculture.  The combined programs in research and education of the USDA and the Land-Grant Colleges resulted in discoveries of improved varieties of seeds and livestock, hybrid seed, fertilizer, new machinery, chemicals for diseases, and weed and insect control.  The educational program provided modern agricultural information to farmers through extension workers.  With changes in...

PRICE ANALYSIS, AND ALTERNATIVE METHODS OF MARKETING PLUMS IN MICHIGAN
Provedor de dados: 31
Autores: McLean,   Canute A.
Plum production is steadily becoming big business in Michigan.  The literature shows that the industry contributes a total value of more than one million dollars annually to Michigan growers.  The industry is relatively young, but so far it has demonstrated an ability for substantial growth.  Its growing importance plus a lack of economic information indicates that economic research is needed for this industry.  This study seeks to examine a number of factors relative to the industry.  First the present state of the industry will be examined along with a comparison with the other competing areas, specifically Washington, Oregon, and Idaho.  Production costs for Michigan and Oregon will be examined and compared.  A short insight will be given into the...

EMPIRICAL COST FUNCTIONS FOR LABOUR-INTENSIVE PADDY FARMS IN FORMOSA
Provedor de dados: 31
Autores: Lin,   An-Yhi; Heady,   Earl O.
This study includes an estimate of cost functions for paddy farms in Formosa. Two types of estimational techniques are used; namely regression estimates and synthesized or budgeted cost curves. Long-run and short-run regression-derived curves are estimated for rice and sweet potato farms from samples which provide the observations. Estimates are for total cost functions with average cost functions computed per hectare. From sample observations, it was possible to derive, through regression estimates, only linear total cost functions. The non-linear average cost functions have only slight (economically unimportant) slopes beyond 2•-5 hectares. Hence, large farms do not seem to be an important policy imperative. However, the steep slope of the average cost...

A Simulation Approach to Risk Assessment in Investment Analysis
Provedor de dados: 31
Autores: Cassidy,   P.A.; Rodgers,   J.L.; McCarthy,   W.O.
A simulation technique is advanced as a means of determining the probability of achieving various possible financial outcomes when assessing alternative investments. To this end a model is constructed and applied to a proposed investment in pasture improvement. Results are contrasted with a deterministic budget approach. The model uses triangular distributions to derive probabilistic estimates for the stochastic events considered. Possible fields of application of interest to agricultural economists are discussed.

A determinação do teor total e do teor solúvel, em diversas soluções, de molibdênio do solo
Provedor de dados: 43
Autores: Catani,R.A.; Alcarde,J.C; Furlani,P.R.
O presente trabalho relata os métodos e técnicas de determinação do teor total e do teor solúvel, em diversas soluções, do molibdênio do solo. O extrato do solo para a determinação do teor total de molibdênio foi preparado atacando-se as amostras com água régia, ácido sulfúrico (1 + 1) e ácido perclórico (1 + 1), Em seguida o molibdênio foi determinado pelo método colorimétrico do tiocianato. A extração do teor solúvel de molibdênio do solo, com diversas soluções extratoras, mostrou que talvez uma solução 0,03 N de NH4F em H2SO4 0,1 N, possa ser usada em análises de rotina para extração do molibdênio do solo, em substituição aos extratores e às técnicas mais morosas, utilizadas para se avaliar o teor de molibdenio solúvel.

Os autores apresentam um trabalho executado em vasos e casa de vegetação em que procuraram estudar a eficiência do calcário dolomítico, como fonte de magnesio, utilizando o fumo (Niootiana tabacum L., var. Goiano) como planta teste. Concluem que o Mg empregado como calcário dolomítico ou como sulfato nao exerceu influencia sobre a altura das plantas nem sobre o peso da materia seca e dimensão das folhas. Contudo, o calcário dolomítico mostrou-se tao eficiente quanto o sulfato de magnesio como fonte deste nutriente, a julgar pela analise química das folhas.

Estudo colorimétrico da montmorilonita I : obtenção da reta padrão e estudo da influência do quartzo e da caolinita na absorbância do sistema colorido
Provedor de dados: 43
Autores: Mendes,A.C. Teixeira; Melo,Wanderley José de.
O objetivo deste trabalho é iniciar estudos no sentido de estabelecer um método colorimétrico para a determinação quantitativa da montmorilonita. E para tal baseou-se na reação deste argilo-mineral com uma solução aquosa de benzidina. Os testes iniciais mostraram que o complexo colorido segue a lei de Lambert-Beer, pelo menos no intervalo de concentração de 7,35 a 36,75 microgramas de montmorilonita por mililitro, sendo que a equação obtida para relacionar a absorbância com a concentração foi : X - 5 L - 14,7 (L é a absorbância e X é microgramas de montmorilonita). Testou-se também a influência da presença do quartzo e da caolonita, chegando-se a conclusão que a presença destes minerais concorre para aumentar a absorçância (embora não houvesse aumento na...

Provedor de dados: 43
Autores: Catani,R.A.; Alcarde,J.C.; Kroll,F.M.
O teor de boro solúvel em água em ebulição cresce com o aumento do volume de água, para um mesmo peso de solo. Êste fato foi constatado nas 6 amostras de solos estudados, quando a proporção de peso de terra: volume de água destilada variou de 10 : 20, 5 : 20 e 2,5 : 20. Por outro lado, a extração do boro de 5 g de solo com 20 ml de soluções 0,05 N de H2SO4 e 0,05 N de acido acético, evidenciou que a solução de acido acético apresentou resultados que recomendam mais estudos no sentido de adaptá-la para a extração do boro solúvel do solo.

Autores: Abrahão,Ibrahim Octavio.
O presente trabalho trata do estudo dos modelos de cristalização do cloreto de cobre (CuCl2.2H(2)0) na presença de extratos de sementes de cafe (Coffea arábica L.), variedade Mundo Novo. Pesquisaram-se 16 concentrações diferentes do sistema água-cloreto de cobre-extrato, com 3 repetições, descrevendo-se individualmente cada urna das series. Os melhores modelos foram obtidos usando-se a técnica de mistura filtrada. Os resultados obtidos permitem recomendar, para cloreto de cobre, concentrações entre 0,5 e 1,0 g/placa e, para extrato, concentrações entre 0,05 e 0,075 g/placa.

Adubação da soja VIII: efeito de doses crescentes de calcário, fósforo e potássio em solo Podzólico Vermelho Amarelo, variação Piracicaba
Provedor de dados: 53
Autores: Mascarenhas,H. A. A.; Miyasaka,S.; Igue,Toshio; Freire,E.S.
O efeito de doses crescentes de calcário magnesiano, fósforo e potássio sôbre a produção de soja foi estudado por dois anos em solo Podzólico Vermelho Amarelo, variação Piracicaba, com pH 5,5, adubado com fósforo nas três culturas anteriores à experiência. Não houve resposta à adubação potássica. A reação ao calcário só se manifestou no segundo ano, quando a dose menor, de 1 t/ha, aumentou a produção em 9%. O efeito do fósforo foi significativo e linear; contudo, em média dos dois anos, o aumento proporcionado pela dose maior, de 100 kg/ha de P2O5, correspondeu a apenas 9%.

Autores: Gallo,J. Romano; Hiroce,Rúter; Bataglia,O. C.; Moraes,F. R. Pupo de.
Em amostras de 134 cafèzais, distribuídos nos principais grupos de solos do Estado de São Paulo, colhidas em três estações do ano, foram determinados 12 elementos químicos essenciais, sódio e alumínio. A percentagem de cafèzais deficientes em nitrogênio foi superior a 80% em todos os solos. No Podzolizado de Lins e Marília, o segundo elemento em falta foi o ferro. No Latossolo Roxo, depois do nitrogênio, a maior deficiência foi a de potássio e zinco; no Podzólico Vermelho Amarelo-Orto, a de boro.

No ano agrícola de 1965/66, em plantas de arroz cultivadas em terras altas, sem irrigação e com pH que variava entre 5,75 e 6,90, localizadas nos municípios de Miguelópolis, Leme e Campinas, foram notadas anomalias que se caracterizavam por afetar as plantas desde duas semanas após a germinação, causando morte a algumas delas. As fôlhas mais velhas apresentavam-se com coloração castanho-escura, exceto ao longo dos bordos e da nervura principal, que conservavam a côr verde normal. Algumas fôlhas, além dêsses sintomas, apresentavam o têrço inferior com tonalidade verde-amarelada; outras mostravam-se partidas no sentido do seu comprimento. Resultados obtidos com adubações qualitativas e quantitativas de zinco e pela análise química das plantas evidenciaram...

Efeitos das adubações nitrogenada e fosfatada, da calagem e da aplicação de micronutrientes foram investigados através de ensaios de campo em cultura de arroz (Oryza sativa L.), em solos do Vale do Paraíba, no Estado de São Paulo. Os níveis de nitrogênio e fósforo foram de 0, 40 e 80 kg/ha; para o calcário, em solos orgânicos, de 5 t/ha, e nos argilosos de 3 t/ha; os micronutrientes entraram nas dosagens usuais. Os resultados mostraram sempre grande reação ao nitrogênio, inclusive à dose de 80 kg/ha. Para o fósforo, as reações foram muito menores, e somente em parte dos casos houve aumento de produção. Não se observou reação ao calcário e aos micronutrientes.

Bambu como matéria prima para papel: estudo de processos de cozimento em material de Bambusa tuldoides Munro
Provedor de dados: 53
Autores: Ciaramello,Dirceu.
Três processos de cozimento - soda, soda-enxôfre e sulfito neutro de sódio - com várias dosagens de reagente, foram estudados para a obtenção de pasta crua para papel, com material de Bambusa tuldoides Munro. Os maiores rendimentos foram obtidos com o sulfito neutro, seguido do soda-enxôfre. O emprego exclusivo da soda, em dosagem igual ou superior a 20% do pêso sêco dos cavacos, trouxe queda no rendimento. Nos testes físico-mecânicos, os papéis se mostraram altamente porosos e resistentes ao rasgo, mostrando-se o material promissor na produção de pasta não branqueada, semelhante a "kraft" de pinheiros. As diferenças, entre os diversos cozimentos, com relação às características do papel foram pouco acentuadas. Para aprodução de celulose branqueada, o...

Efeito de diferentes fertilizantes nitrogenados no aumento da produtividade do arroz irrigado
Provedor de dados: 53
Autores: Leite,Norberto; Gargantini,Hermano; Gomes,A. Gentil; Igue,Toshio.
Foi estudado o efeito, na cultura de arroz (Oryza sativa L.) irrigado, de diferentes doses e tipos de fertilizantes nitrogenados, bem como a conveniência da construção de diques separando as parcelas. Foram estudados três níveis de nitrogênio e três tipos de fertilizantes, na presença de fósforo e potássio constantes. A variedade utilizada foi a Iguape-agulha. Os dados mostraram grande efeito da adubação nitrogenada, no aumento da produção do arroz. O maior aumento foi apresentado pela torta de mamona, seguida do sulfato de amônio e do nitrocálcio. A presença de diques de separação de canteiros não se mostrou necessária, para evitar a interferência da adubação nitrogenada, em canteiros vizinhos, mesmo utilizando adubos altamente solúveis.

Experiências com variedades de soja foram conduzidas na Estação Experimental Central "Theodureto de Camargo", em Campinas, e no Campo de Pesquisas do Serviço do Vale do Paraíba, em Água Preta, Pindamonhangaba, visando a produção de grãos ou de forragem, durante o inverno. Nesse período, em que prevalecem dias curtos e baixas temperaturas, verificou-se que o cultivar Aliança Preta-1 pode fornecer excelente produção de grãos (1.700 kg/ha) e que o cultivar Santa Maria-1 tem comportamento muito bom como forrageira, apresentando produção de massa verde da ordem de 22 toneladas por hectare. O comportamento dos cultivares mencionados sugere a existência de germoplasma indiferente ao fotoperiodismo e tolerante a baixas temperaturas.

Autores: Conagin,Cândida H. T. M.; Pinto,Alcides J. D'Andréa.
O presente trabalho reune observações morfológicas e citológicas em dez cultivares e cinco espécies de Pelargonium aromático e em onze cultivares ornamentais. Os cultivares aromáticos são, morfològicamente, muito semelhantes ao P. x asperum, do qual possivelmente devem ter-se originado; apresentam meiose irregular, com alta freqüência de monovalentes. Os cultivares ornamentais pertencem todos à espécie P. zonale, e dentre êles uns são diplóides e outros tetraplóides. Das espécies em coleção algumas se identificam com as descrições anteriores, mas outras devem ter sido introduzidas erroneamente classificadas. Considerando o material estudado, foram encontrados, para Pelargonium, três números básicos de cromossomos: x = 8, x = 9 e x = 11.

Seleção do algodoeiro para resistência à fusariose em área onde ocorre doença semelhante em plantas de labelabe (Dolichos lablab L.)
Provedor de dados: 53
Autores: Gridi-Papp,Imre L.; Fuzatto,Milton G.; Ferraz,Carlos A. M.; Cia,Edivaldo.
Em área de Latossolo Roxo, localizada na Estação Experimental "Theodureto de Camargo", em Campinas, verificou-se incidência de doença provocando "murcha", com sintomas internos caracterizados pelo escurecimento dos vasos, sucessivamente em plantas de labelabe e em algodoeiro. Em ambas as espécies vegetais determinou-se a presença de fungos do gênero Fusarium, mediante isolamento feito em plantas doentes. Seleções, feitas na referida área, de plantas pertencentes a linhagem de algodoeiro suscetível à murcha de Fusariumderam origem a linhagens que revelaram apreciável resistência quando testadas em solo infestado por Fusarium oxysporum f.vasinfectum (Atk.) Snyder &amp;amp; Hansen. São discutidos aspectos relacionados com a possível descoberta de nova fonte...

Efeito da calagem e da adubação fosfatada em solo ácido e de baixa fertilidade, na cultura de trigo
Provedor de dados: 53
Autores: Igue,Kozen; Gargantini,Hermano; Alcover,Milton.
São apresentados resultados experimentais, em cultura de trigo (Triticum sativum, L.), da aplicação de calcário e adubação fosfatada, em diferentes níveis e formas de aplicação, em Latossolo Vermelho Escuro-Orto, da Estação Experimental de Capão Bonito, de baixa fertilidade e ainda não adubado anteriormente. Mostraram-se elevados os efeitos do corretivo e do fertilizante fosfatado. A dose mínima de calcário, ou seja, 2 t/ha, provocou o mesmo efeito que a dose dupla. Com o fósforo, a produção cresceu com o aumento de fertilizante.

Provedor de dados: 53
Autores: Leitão Filho,Hermógenes de Freitas.
É apresentada a descrição de uma nova espécie arbórea do gênero Stifftia, nativa em matas primárias do litoral Norte do Estado de São Paulo. A referida espécie apresenta porte de 2,0-3,0 metros de altura, com fôlhas simples alternas, lanuginosas. Flores dispostas em inflorescência terminal sub-séssil, com 1-5 capítulos em cada ramo. O invólucro dos capítulos apresenta 8-10 séries de brácteas, externamente lanuginosas. Flores com corola amarelada. O fruto é um aquênio de coloração escura, quase preta, encimado por papus unisseriado e vermelho. A nova espécie é conhecida há, pelo menos, quarenta anos, como pode ser demonstrado pelas exsicatas depositadas nos herbários do Instituto Agronômico e Instituto de Botânica. Sob cultivo, a nova Stifftia é encontrada...

Determinação da disseminação do vírus do enrolamento em batatal para semente pelo uso de plantas indicadoras
Provedor de dados: 53
Autores: Cupertino,F. P.; Costa,A. S.
Foi verificado haver correlação entre a manifestação de sintomas nas plantas indicadoras intercaladas no batatal para semente e a disseminação, nêle, do vírus do enrolamento das fôlhas. Médias de 12 ensaios realizados em vários pontos do Estado de São Paulo deram os seguintes valores: 49,6% em Datura stramonium, 34,0% em Physalis sp. e 28,5% em tomateiro Santa Cruz. Somente 0,9% das plantas de batata mostraram sintomas de infecção primária pelo vírus, embora a infecção no campo tenha realmente sido de 23,6%. É sugerida a introdução do uso de plantas indicadoras na legislação que regulamenta a produção de batata-semente certificada como método auxiliar para estimativa do teor do vírus do enrolamento nos tubérculos produzidos.

Provedor de dados: 53
Autores: Leite,Norberto; Gargantini,Hermano; Hungria,Luiz S.; Venturini,W. R.
São relatados os efeitos produzidos pela aplicação de bórax na cultura da batatinha (Solatium tuberosum L.), em solos de várzea irrigada do Vale do Paraíba. Quatro doses de bórax - 10, 20, 30 e 40 kg/ha - foram aplicadas de três maneiras distintas: no sulco de plantio, em cobertura (vinte dias após a germinação) e parceladamente em 4 pulverizações foliares semanais. As melhores doses de bórax foram as de 10 e 20 kg/ha, aplicadas no sulco de plantio, em mistura com os demais adubos. As aplicações em pulverização provocaram sintomas de toxidez nas folhas, notadamente as de maiores doses.
