Provedor de dados: 14
Desde as ultimas reuniões técnicas, vem-se notando a grande necessidade de correlação e intercâmbio mais efetivo entre as diferentes frentes de trabalho da DPP (Ex-EPFS). Embora se tenha programado excursões de estudos de campo as diferentes áreas em que a DPP desenvolve suas atividades, nem sempre foi possível realizá-las devido, principalmente, a escassez de recursos financeiros para tal objetivo. Portanto, esta pode ser considerada como a primeira excursão de estudos de correlação em que foram visitadas três frentes de trabalho, com a participação integral dos técnicos responsáveis pelo Levantamento dos Solos do Território Nacional. Teve a duração de 21 dias, compreendidos no período de 2 a 22 de julho de 1968. Foram percorridos 5.080 km de estradas e...

Microstructures de coquilles larvaires de prosobranches au microscope électronique à balayage
Provedor de dados: 5
Autores: Thiriot-qievreux, Catherine.
The observation of the planktonic larval shells of different species of Prosobranches is carried out with scanning electron microscopy (Cambridge, Stereoscan 4). The influence of different fixing agents (non-acetified) on the conservation state of larval shells is not really clear at low magnifications. On the contrary, at high magnifications, the results are clearly better after using an alcohol fixation or without any fixing agent at all. The morphological differences of the larval shells of four species of Philbertia: P. gracilis (Montagu), P. linearis (Montagu), P. leufroyi (Michaud) and P. purpurea (Montagu) are precised. The microstructure of the shells of Firoloida desmaresti Lesueur and Atlanta fusca Souleyet larvae is observed. Scanning electron...

Observations de fronts internes dans le détroit de Gibraltar pendant la campagne océanographique OTAN 1970 et interprétation des résultats par un modèle mathématique
Provedor de dados: 5
Autores: Cavanie, Alain.
MM. Lacombe, Frassetto and Ziegenbeim's observations, based on different measurement methods, demonstrated the existence of inner fronts and short period oscillations at the interface separating the Atlantic and Mediterranean waters in the eastern part of the Gibraltar straight. These observations show that inner fronts are created by the following mechanism: during the incoming tide, the westward current pushes the Mediterranean waters against the threshold of Gibraltar and, when getting to high tide, when the tide current becomes null, the interface is far from a balanced position, too high to the east, too low to the west of the threshold. The density currents caused by this imbalance creates an inner front of amplitude of more than 50 m which moves...

Structural framework of selected regions of the western mediterranean 1. Valencia basin
Provedor de dados: 5
Autores: Pautot, Guy; Auzende, Jean-marie; Olivet, Jean-louis; Mauffret, Alain.
The alignment of the Balearic Islands, stretching from the Spanish mainland towards the Corsican-Sardinian block, has long intrigued many geologists. Since Suess (1886), we know that the Balearic block (Ibiza, Formentera, and Majorca) is part of the Alpine system. Many authors (Kober, 1914; Staub, 1928; Kober, 1931) have subsequently attempted to comprehensively integrate the history of the Balearic block within the history of the Alpine chain. In this paper, we will use data from marine geology and geophysics to define the location of the Balearic Islands during the diverse phases of distension, shearing, and compression between the European and African plates, which created the present western Mediterranean and the Alpine chain. In particular, we will...

Les sites favorables à l'aquaculture sur les côtes bretonnes

This inventory of sites favourable for aquaculture on the coasts of Brittany involves the joint goal of the French National Centre for the Exploitation of the Oceans (CNEXO) and the Brittany Region that aims to reserve certain sites to install the structures necessary for aquaculture. The CNEXO continues its efforts, initiated several years ago, to promote aquaculture on French coasts. The Brittany prefecture was the first to request this type of study and wishes to integrate aquaculture as part of coastal spatial planning. The Aquitaine prefecture has since then also requested a similar study that is now in progress. Aquaculture in France is now in a transition period between an experimental phase and the industrial-scale implementation phase. A certain...

Premiers éléments de comparaison entre l'huître portugaise et l'huître japonaise
Provedor de dados: 5
Autores: His, Edouard.
L'introduction d'une nouvelle espèce d'huître donne souvent lieu à des débats passionnés dans les milieux ostréicoles. Ch. MARTIN en donne un exemple dans son ouvrage "Agriculteurs de la Mer" ; il rapporte les mesures restrictives qu'avait entraînées l'importation de l'huître portugaise à Arcachon au début du 20e siècle. Un des arguments avancés pour expliquer les réticences était celui de la "concurrence vitale" et de la compétition sur le plan nutritionnel entre Crassostrea angulata et Ostrea edulis, l'huître plate, qui était alors seule exploitée dans la baie. Il fallut attendre les mortalités massives de 1920, qui anéantirent presque complètement la "gravette", pour que soit envisagée une reconversion de l'ostréiculture par l'exploitation de l'huître...

The observation of a series of young individuals of growing size, belonging to the abyssal species Plutonaster bifrons (Wyv. Thomson), with scanning electron microscopy, shows the appearance and development of morphological structures. An animal of R = 5.55 mm presents enough characters to identify the species, but if its size is smaller than R = 0.85 mm, one witnesses a significant development of some specific characters.

Choix de produits pour lutter contre la pollution du milieu marin par les hydrocarbures. I. Motif du choix.
Provedor de dados: 5
Autores: Soudan, France.
Following the Torrey Canyon disaster, attention was directed to finding effective but innocuous means to combat the pollution risk of shipping oil. To introduce the minimum of chemicals into the sea, it was decided to use a little of a strong, but possibly more harmful, substance rather than more of a weaker and less offensive one. Marine life could be affected mechanically, chemically or by removal or dissolved O sub(2). Various products were tested under laboratory conditions for effectiveness, and possible effects on marine life. It is noted that the latter is only a short-term view, and that different results might be obtained using different species as indicators. The range of effectiveness of products was considered. It was concluded that low density...

Seismic refraction on continental shelves with detectors on sea floor
Provedor de dados: 5
Autores: Avedik, Felix; Renard, V.
Seismic refraction at sea and on continental shelves requires most of all a precise positioning of the shooting and receiving stations and a good signal to noise ratio. A new system has been developed using detectors anchored on the sea floor and radio transmission of signal for refraction work on continental shelves.  This technique satisfies both requirements. The system has been tested in the western Channel in December 1971. [NOT CONTROLLED OCR]

Etude bathymetrique et sedimentologique des etangs de Diane et d'Urbino en Corse.
Provedor de dados: 5
Autores: Longere, Paul; Dorel, Didier; Marin, Jean.
2 ponds (or lagoon) were studied in order to establish the economic possibilities of their exploitation for oysters. Bathymetric and sediment maps were produced using methods described. They indicate a morphological similarity between the ponds, with a superficial broken bed and a regular, flat or gently sloping bed beyond 7 m, the general form reflecting the aerial relief of the adjacent `coast'. The deeper regions had mud or clay sediment, while the edges of the ponds were covered with sand. In more detailed studies it was evident that the banks of Diane were more regular and steep than those of Urbino, and that only in the latter was there a good relationship between the depth of water and the carbon/nitrogen ratio. Differences are thought to relate to...

Volcanics from the walvis ridge
Provedor de dados: 5
Autores: Hekinian, Roger.
THE Walvis Ridge is a non-continuous aseismic feature  in the south-eastern Atlantic Ocean with a general trend north-east/ south-west.  Close to the principal interruptions of the ridge is a north-south topographiç lineation shown on Simpson's map  (Fig. 1).  The ridge appears to be attached at its northeast end to the shelf of Angola and South-west Africa and at its south-west end to the east flank of the Mid-Atlantic Ridge through two volcanic islands,  Tristan da Cunha and Gough (Fig. 1). These two islands are made up of recent alkalibasalt-trachyte suite². . The geology of the Walvis Ridge has remained relatively unknown. [NOT CONTROLLED OCR]

Those found in (1) deep mud at 500-1200 m, (2) muddy sand at 20-340 m, (3) shelly sand at 30-52 m are considered in turn. Group (I) varied according to the station of collection, and were affected by factors in addition to depth, such as the presence of corals. Muddy sand was poor in large individuals and in empty shells, but contained many displaced littoral forms. The very few living forms found in the shelly sand area was surprising; it may reflect the constant agitation of the sand or the small size of individuals, which could...

Un agent de la géodynamique littorale : la houle
Provedor de dados: 5
Autores: Thomas, Yves-f.
L 'étude de l'évolution géomorphologique des domaines infra et intertidaux, ainsi que lorsqu'il y a lieu, le proportionnement des ouvrages de défense des côtes, constituent un préalable à l’implantation d’infrastructures (infrastructures portuaires) ou d'activités diverses (exploitation des agrégats) sur la frange maritime du milieu littoral. Il en résulte une nécessaire connaissance de la cinématique des eaux marines à proximité du, voire à même le rivage. L 'objet de cette étude est la présentation du facteur houle, agent de la dynamique des fonds. Aussi traiterons nous succèssivement: - l'observation de la houle - le traitement de l'information - l'intérêt géodynamique des études de houle après quoi, il sera présenté un exemple de régime de houle :  -...

Rapport de mission à la Réunion, Etude des possibilités d’un développement de la conchyliculture sur le littoral de l'Ile, 23 février - 1er avril 1972
Provedor de dados: 5
Autores: Trochon, Pierre.
Le but de cette mission, demandée par la Préfecture du Département, était d'étudier les possibilités d'un développement de la conchyliculture sur le littoral de l'Ile. Il convenait de faire l'inventaire des ressources naturelles en huîtres et moules comestibles pouvant permettre le développement d'une ostréiculture et d'une mytiliculture analogues à celles qui existent en métropole. Dans le cas où il n'y aurait pas de gisements naturels exploitables, la mise en élevage de jeunes huîtres et moules importées à partir de pays producteurs devait être envisagée.

Sur un copépode parasite de l'huître portugaise (Crassostrea angulata Lmk) dans le bassin de Marennes- Oléron
Provedor de dados: 5
Autores: Comps, Michel.
Dans le bassin de Marennes-Oléron, à partir de l’hiver 1970, on a observé chez Crassostra angulata la présence d’un copépode fixé sur les branchies. Cet organisme a attiré l’attention de certains ostréiculteurs et ce, d’autant plus qu’il n’était rencontré que chez les huîtres immergées dans des claires. Ce copépode posséderait des caractéristiques morphologiques proches de celles des Pseudomyicolidae

Nouvelles especes de Nannastacidae (Crustaces, Cumaces) dans les eaux sahariennes de l'Atlantique.
Provedor de dados: 5
Autores: Bacescu, M.; Muradian, Zarui.
While only 4 species were known for the family Nannastacidae in West Africa, a recent study has revealed 11 more species - Procampylaspis maurini, P. arguini, P.thalassae, Cumella africana, Schizotrema atlantica, Campylaspis macrophthalma, C. mauritanica, C. bonetti, C. legendrei africana, C. jonesi. Of these, S. atlantica and the last 4 Campylaspis species are new species, and are described. Both male and female adults are described, with explanatory diagrams, and additional observations are included. The species of Campylaspis are incorporated modified form. It is thought that this description completes not only acquaintance with the fauna of the Saharian section of the Atlantic, but also the whole of the Atlantic Ocean.

The analysis of the geological and geophysical data on the North African basin and its edges highlighted the importance of a group of accidents in the NE-SW direction, embodied by the Alboran and Emile-Baudot ridges and the northern Tunisian fracture zone. A recent work (Auzende et al., London, Feb. 1972) showed that this family of accidents could be interpreted as a unique system of transforming faults linked to the creation of the North African basin.

Comments on 'Thermal Effects of the Formation of Atlantic Continental Margins by Continental Break up' by N.H. Sleep
Provedor de dados: 5
Autores: Foucher, Jean-paul; Le Pichon, Xavier.
Sleep (1971) has presented some very interesting observations on the exponential decrease of the subsidence rate in coastal basins. He shows that the time constant of this exponential decrease is of the same order of magnitude that the thermal time constant of a lithospheric plate. He then makes calculations with a physical model combining erosion and thermal contraction. The purpose of these comments is to show that his physical assumptions are invalid and that çonsequently his calculations are grossly in error. [NOT CONTROLLED OCR]

Mesure de la demande chimique en oxygène dans l'eau de mer.
Provedor de dados: 5
Autores: Michel, Pierre.
Introduction: Measuring the chemical oxygen demand (COD) is a way of determining the organic matter in water based on its oxidisibility by bichromate. The presence of organic matter in sea water is one of the factors that determines the productivity of the oceans: whether this organic matter will be absorbed directly or must first be transformed into nutritive substances by bacteria. This beneficial action also has its limits. On the one hand, consumption of organic matter remains limited; when it exceeds a certain rate, there is no longer any increase in productivity. On the other hand, the excess organic matter deteriorates by consuming the dissolved oxygen and thus competes with marine life. In extreme cases, this excess can cause the eutrophication of...

Reconnaissance des fonds de pêche de la Guyane française - Campagne de la "Thalassa" dans la région Antilles-Guyane 15 juin - 1er septembre 1971
Provedor de dados: 5
Autores: Abbes, R; Aldebert, Yvonne; Dorel, D; Leroy, C; Le Men, R; Prado, J; Saint-felix, C; Commandant Corre,.
Les résultats des recherches effectuées par la "Thalassa", au cours de l'été 1971, sur le plateau de la Guyane française, montrent qu'à cette période de l'année les rendements étaient nettement insuffisants pour donner lieu à une exploitation rentable de la part des flotilles de pêche qui avaient d'ailleurs déserté ce secteur. Toutefois, la courte durée de la campagne ne permet pas d'extrapoler ces résultats à un cycle annuel complet car on connaît mal le comportement des crustacés et des poissons de cette région en fonction des variations du milieu. Les conditions hydrologiques rencontrées sont, en effet, sujettes à des fluctuations plus ou moins importantes, notamment dans la couche superficielle qui est influencée par les apports irréguliers de...

Experiences de reproduction artificielle de Loup Dicentrarchus labrax (Linne 1758).
Provedor de dados: 5

Mature eggs were expressed from captured female and fertilised artificially with slightly bloody sperm, in dry conditions or in a humid atmosphere, both at 13 degree C. The best incubation conditions proved to be 13 degree C, with streptomycin and penicillin. Another sample was kept at 18 degree C. Hatching occurred after 4 or 5 days, larvae showing positive phototropism. The system of renewal of water and artificial food is described. The embryonic reserve drop of lipid disappeared between day 14 and 16. Observations on larvae were like previous ones, but live larvae had larger mouths than had fixed specimens, and it was found that temperatures of 13 degree C or 18 degree C were suitable beyond the egg stage. A sudden change in temperature caused by a...

Consequences du cycle de mue et d'intermue sur la morphologie fonctionnelle des pars molaris des Crustaces Peracarides.
Provedor de dados: 5
Autores: Saudray, Yves.
The anatomy of the masticatory part of the mandible (the pars molaris) has been studied throughout the moult/intermoult cycle in some peracacarid crustacean species, by scanning electron microscopy. Species examined were: Ligia oceanica, Sphaeroma serratum, Idotea balthica, Talitrus saltator, Hyale nilssoni, Gammarid amphipoda and the mysid Pranus flexuosus. Feeding is known to decline near moulting; this may be because the chewing surfaces become loosened before moulting. Also the surfaces are worn down and useless, and feeding ceases. Very long intermoult periods, as found in old individuals, may thus cause long periods of starvation and this could enhance the symptoms of senescence.

Structural framework of selected regions of the western mediterranean
Provedor de dados: 5
Autores: Olivet, Jean-louis; Pautot, Guy; Auzende, Jean-marie.
The Alboran Sea (Figure 1) is a narrow sea (200 km wide), closed on the West by the "Arc of Gibraltar" and opening in the east into the Balearic Basin. The Betic chains extend along its northern border, the Rif chain extends along its southwest border, and its southern border is essentially formed by the Atlas Foreland. The Betico-Rif ensemble forms an arc having divergent structures (dipping away from the Alboran Sea). South of the sea, the Rif structures turn towards the northeast in contact with the autochthonous and semiautochthonous Atlas Foreland. The Rif and the Betic chains are affected by numerous northeast-southwest and northwest-southeast lateral faults whose role seems important (Kornprobst, 1971; Andrieux et al., 1971 ; Jacquin, 1970), but is...

Portuguese oysters, C. angulata from brood ponds at Arcachon (salinity 27-28ppt) were exposed to lowered salinities and their valve activity continuously recorded. Down to 2 ppt, normal activity was resumed within 24 hours, between 8 and 11%, oysters, survived and adapted slowly, below 8%, oysters died. Sexually mature oysters are more susceptible and may die at 10 to 8% salinity, perhaps because the gonad is full of gametes. Oysters from different localities probably respond differently to changed salinity.

Marginal fracture zones as Structural framework of continental margins in south atlantic ocean
Provedor de dados: 5
Autores: Francheteau, Jean; Le Pichon, Xavier.
A plate tectonic model of the early opening of the south atlantic is used to des cibe the structural framework of the continental margins and adjacent oceanic and coastal areas on both sides of the ocean. It is proposed that major offsets of the continental margins necessarily induce the subsidence of coastal basins where fracture zones intersect the continents. The configuration of the accreting plate-margin boundary gradually developed throughout the opening of the ocean after Late Jurassic time. [NOT CONTROLLED OCR]

Contribution de la gravimétrie à l'étude de la Bretagne et du plateau continental adjacent
Provedor de dados: 5
Autores: Sibuet, Jean-claude.
The detailed interpretation of gravimetric surveys implies a good knowledge of the superficial geology, at least in specific spots such as the basement's outcrops. We now have a geological sketch map as well as an estimate of the thickness of the sedimentary series of the continental shelf off the coasts of Brittany. As a consequence, it is now possible to try and interpret the new map of this region's gravimetric anomalies, based on the terrestrial and marine geological data.

L'état de la mer sur les côtes de France
Provedor de dados: 5
Autores: Thomas, Yves-f.
Une première approche valable des problèmes littoraux réside dans la connaissance des informations climatologiques et des possibilités qu'elles offrent aux usagers, tant en ce qui concerne par exemple, les possibilités de travail en mer, que la navigation de plaisance ou autre forme de récréation littorale.  En effet, partant des observations immédiates et brutes, la climatologie peut être définie comme une information statistique élaborée que les usagers peuvent considérer comme une forme de prévision à longue échéance.  En novembre 1970, un groupe de travail de l'Organisation Météorologique Mondiale a dressé, à Genève, la liste des besoins des usagers en données météo-océanographiques et a retenu les paramètres suivants : - vent de surface - mer et houle...

Autores: Perez, René.
Laminaria digitata is the only brown alga used in the French alginate industry. Air-dried and flash-dried (in a current of air at 200 to 850 degree C) algae were compared. Quality was assessed viscometrically and the results expressed graphically. Quality after drying and keeping properties were found better in flash-dried algae and the method was shown to be the cheapest of methods currently available.

Identification des especes du genre Spicara par electrophorese des proteines du cristallin.
Provedor de dados: 5
Autores: Pollard, David A.; Pichot, Paul.
Confusion has arisen over the nomenclature of certain fish of the family Centracanthidia, because of the colour variations due to sexual dichromatism, sexual inversions, protogynous hermaphroditism, and seasonal modifications according to the stage of maturity. A historical survey of nomenclature is presented for species described under the genera Maena, Smaris and Spicara, the last being the most recent. A morphological study and an electrophoretic study of the crystalline lens of the various species involved is described. The techniques and standards used are given. As a result of the study, and bearing in mind the effects of the variations mentioned above, it was concluded from electrophoretic comparisons that only 2 species are valid, Spicara maena and...

Autores: Le Borgne-david, A.
The Portuguese oyster (Crassostrea angulata) and the sea-squirt Ciona intestinalis are both filter-feeders and compete for space in the oyster beds. Valve movement in oysters and shortening and elongation in Ciona were recorded on a smoked drum. Oysters showed a slow (3 one half min) spontaneous opening/closing rhythm, which was speeded up by stimulatory (vitamin) substances and increased in amplitude by toxic accumulated waste substances, or sudden change in temperature. Ciona showed a regular contraction rhythm of similar to 1 min and single sharp shortening after a strong light stimulus or a food particle touch stimulus to the oral tentacles. The neural ganglion discharges spikes 3 times faster than in the dark, after light stimulation. Filtration rates...

Observation océanographiques dans le détroit de Gilbraltar pendant la campagne Phygib (Septembre - Octobre 1971)
Provedor de dados: 5
Autores: Cavanie, Alain.
Measurements in the strait of Gibraltar during the last fifteen years have shown the existence of large internal waves propagating at the interface between the upper layer of Atlantic water and the lower layer of Mediterranean water.  These waves are generated by the tidal currents running over the sill. The scale of the phenomena are such that non linear variations of the flow in the strait as a fonction of the tidal amplitude can be expected. Specifically, mean Mediterranean outflow over a tidal period should be expected to increase going from neap to spring tides. To study these effects, two currentmeter and hydrological stations were made by the N. O. Le Noroit by the C.0.B.'s physics group in october 1971. The first series of observations made at the...

French fishermen have been fishing porbeagle shark Lamna nasus on the edges of the continental shelf, from the Bay of Biscay to the south of Ireland. Incidentally, until the past few years, when, during summer, bluefin tunas Thunnus thynnus, albacores Thunnus alalunga and sworfishes Xiphias gladius were caught on the same line. Since 1970, some fishermen have started focusing on swordfish. The authors describe the technique and gear used for this fishery. A fishery that could largely develop in the years to come.

Histoire Sédimentaire de la Région au large de la Côte d'Azur
Provedor de dados: 5
Autores: Pautot, Guy.
Detailed investigation of a portion of the sea-floor off the French Riviera serves to detail the history of the Algéro-Provençal Basin. The chemical composition and physical properties of sediments and the stratigraphy and structural framework are considered together. Both stratigraphy and structural framework of the sedimentary cover are examined by means of deep drilling, coring and seismic reflection. It appears that the unconsolidated sedimentary cover of the continental slope is Plio-Quaternary in age. This cover displays abundant slumping structures which have resulted from contemporaneous tectonic movements.  The basement south of Cannes corresponds to an extension of the crystalline Maures Massif which subsided during Mio-Pliocene time. The central...

Découverte du genre abyssal Fauveliopsis (Annélide Polychète) en Méditerranée occidentale
Provedor de dados: 5
Autores: Laubier, Lucien.
A member of the genus Fauveliopsis (Annelida Polychaeta flabelligeridae) was discovered in different stations of the western Mediterranean abyssal plain. Already known in the northern Atlantic Ocean, this species most probably exists in the northern Pacific Ocean as well. Its abundance in the western Mediterranean Sea leads us to review a number of notions on the absence of a real abyssal fauna in this sea and on the extreme paucity of the deep plain between 2 000 and 3 000 m.

Autores: Lahaye, Jacqueline.
Representative species of the families Pleuronectidae, Bothidae and Soleidae were studied throughout the year. Changes are described which were seen in the ovaries, and photographs of cross sections of the tissue are shown. The progress of egg release was noted, and in some cases correlated studies were made of gonadal changes in male. The period of egg release was prolonged over 1 one half -2 months for plaice and turbot, and for 6 months for sole. Individual fish showed these extended periods of laying, and the actual months of the year differed for each species. The massive mobilisation of reserves which necessarily accompanied the release of large numbers of eggs was reflected by turbot, in sperm production. In addition, the increase in gonadosomatic...

Comportement des thons et techniques de pêche. Essai d'éthologie halieutique des Thunnidae

Autores: Havard Duclos, F; Havard Duclos, François.
Five techniques are currently used in tuna fishery worldwide. They are, in order of appearance, fixed net (madrague), mobile line, living bait, ring net (seine) and longline. The efficiency of these different methods is variable, but it has been observed that those impacting on the behaviour of the fish or of the shoals (bait boats and seiners) show better performances. Madragues are indeed positioned in spots known to fishermen to be on bluefins (Thunnus thynnus) migratory roads.

Structural framework of selected regions of the western mediterranean 2. Balearic islands : southern prolongation
Provedor de dados: 5
Autores: Auzende, Jean-marie; Olivet, Jean-louis; Pautot, Guy.
In a recent note (Mauffret et al, in press) we described the extension of the acoustic basement south of the Balearic mainland. One series of arguments (position, morphology, and magnetism) led us to advance the hypothesis that the acoustic basement represents a prolongation of the Balearic continental basement towards the south at least as far as 38' 30'N latitude. The prolongation appears to be marked by a large topographic rise between the 1000 and 2600 meter isobaths. Figure 1 (Mauffret et al, in press) schematically shows the continuation toward the south of this supposed Balearic continent. DSDP Leg 13 Drill Site 124 was located near 5°E longitude and 39°N latitude at the inferred southeast extremity of the sunken "Balearic continent". With reference...

C'est ainsi que nous avons mis au point et utilisé en laboratoire un dispositif simple qui nous a permis de rechercher les limites de tolérance de l'huître portugaise à la salinité, ou d'étudier son comportement en milieu confiné, avec dans ce dernier cas, description des symptômes d'intoxication. De même nous avons pu enregistrer sur notre appareillage les myogrammes particuliers qui accompagnent l'émission des produits sexuels.

To assess the potential fishery for Pandalus borealis, the R/V `CRYOS' made cruises, in 1970 off SW Newfoundland and in 1971 off Nova Scotia. The trenches where Pandalus is found and the 3 types of trawl (large mouth, balloon and flat) are described. Details of size of catches and of individuals, and also of fish species caught are given. Prawn stocks in these grounds seem to match those of grounds already being exploited. Significant fish catches may also be expected (e.g. skate, herring and cod). Canadian type trawlers of ~ 65 ft would be suitable to exploit this fishery.

Opening of the Alboran Sea
Provedor de dados: 5
Autores: Le Pichon, Xavier; Pautot, Guy; Weill, J.p.
The Alboran Sea contains two basins deeper than 1,000 m separated by a ridge which we shall call the Alboran marginal fracture (Fig. 1).  Seismic reflexion studies and data from the Joides drill site 121, situated exactly on the northern limit of the western basin, show that the deepest sedimentary layers, lying on the substratum, are older than upper Burdigalian (14 m.y.), but probably younger than lower Aquitanian (23 m.y.)1.  But we do not know whether the substratum of the deep basins is young oceanic crust or foundered continental crust. Here we shall assume that the portions of the basins deeper than 1,000 m indeed consist of new surface created by the separation of two rigid plates during the Middle Miocene, and we shall discuss whether the...

Depuis plusieurs années on a constaté une baisse sensible de la productivité dans l'exploitation des parcs et claires à huîtres du bassin de Marennes-Oléron. En outre l'huître portugaise (Crassostrea angulata Lmk) élevée dans cette zone ostréicole devait subir en 1966 et 1967 les effets de la maladie des branchies qui entraîna des pertes appréciables (Franc &amp; Arvy, 1970). Au cours de l'été 1970, parallèlement à des perturbations dans la reproduction, s'amorça une mortalité massive qui au printemps 1971 affectait environ 70% du cheptel.

Crustacés pélagiques susceptibles de pêches expérimentales en atlantique nord et en méditerranée occidentale
Provedor de dados: 5
Autores: Le Gall, Yves; L'Herroux, Michel.
The authors draw up the inventary of pelagic shrimps and Euphausiids which they think, could justify experimental fishing. These species are selected from the results of 150 midwater trawls with "Isaacs-Kidd" ; this sampling was done in order to perform a general study of micronecton in the North Atlantic and in the western Mediterranean. The prospections were carry out mainly within the first 700 meters. For each species choosen a distribution map is supplied showing the location and the date of the most abondant fishing area.

La reproduction de l'Ormeau Haliotis tuberculata L.
Provedor de dados: 5
Autores: Girard, Annie.
In order to improve the regulation of abalone 'fishing' and to provide for the restocking of supplies, more details of the reproductive cycle were sought. Attention is given to gonad morphology, acquisition of sexual maturity, juvenile hermaphroditism, gonad histogenesis and histology of gametogenesis, annual cycle of gamete emission, and the relation between size and fertility. Results are presented in graphs, histograms, diagrams and photographs. It was found that female reached sexual maturity during the 3rd year, at 38-54 mm, male during year 2 at 25-40 mm; there was successive juvenile hermaphroditism; an active period from mid-June to mid-November was indicated by the volumentric index of maturity; water temperature was associated with the...

Sédimentation actuelle et récente en mer d'Alboran
Provedor de dados: 5
Autores: Auffret, Gérard-andré; Pastouret, Léo; Cavanie, Alain; Lanoix, F.
Three processes are called to explain the deposition of hemipelagic muds accounting for around 95 % of deposits in the Alboran Sea during the Holocene: general currents, distal part of a turbidite current, or a combination of these two causes a "gravity-assisted bottom current". We will discuss these hypotheses based on the results of the study of superficial sediment samples and the current measurements conducted during the Polymède II cruise (April-May 1972) by the R.S. "Jean Charcot", as well as on recent works about this region's hydrology (Lanoix, 1972).

Technique canadienne de capture et de marquage du saumon atlantique dans les eaux du labrador et du groenland occidental
Provedor de dados: 5
Autores: Minet, Jean-pierre.
Au mois de septembre 1971, mission nous a été confiée par l'Institut Scientifique et Technique des Pêches maritimes et le Centre National pour l'Exploitation des Océans d'aller étudier les techniques canadiennes de capture et de marquage du saumon atlantique (Salmo salar, LINNE 1758) dans les eaux du Labrador et du Groënland occidental. Cette mission avait pour but de préparer la participation de la France à la campagne internationale de marquage du saumon menée en 1972 dans le même secteur par l'un des navires de recherche de l'ISTPM, le "Cryos" basé à Saint-Pierre-et-Miquelon. Cette expérience intéresse en effet beaucoup la France, 12 des 2 099 smolts de saumons sauvages, marqués en 1969 dans le bassin de l'Adour, ayant été repris au large du Groënland...

Opportunité de l'implantation de l'algue Macrocystis Pirifera sur les côtes bretonnes
Provedor de dados: 5
Autores: Perez, René.
Nous allons prochainement effectuer des expériences dont le but est de déterminer si l'algue Macrocystis pirifera qu'on ne rencontre pas sur les côtes françaises pourrait y vivre si elle y était implantée. L'annonce de ces essais risquant de provoquer quelques inquiétudes chez certains chercheurs insuffisamment informés, il nous semble bon d'expliquer les raisons qui nous poussent à entreprendre ces travaux et d'exposer la méthode choisie de façon à montrer qu'il ne s'agit pas d'une tentative hasardeuse mais d'une expérience soigneusement préparée. Nous mettrons aussi l'accent sur la faiblesse des risques et sur les nombreux avantages qu'une telle acclimatation pourrait apporter.

Evolution de la sédimentation pendant le Néogène en Méditerranée d'après les Forages JOIDES-DSDP

Examination of the GLOMAR CHALLENGER cores in the Mediterranean Sea (Leg 13) enables us to distinguish three main lithological units in the Neogene series. The lower unit is composed of blue marls with a poor, or dwarfed, fauna. The marls are of Langhian, Serravalian and Tortonian age, and are very similar to the blue marls of the same age known on land (in the Rhône basin, Vienna Basin, the Panonic Basins, etc.). This suggests that the Vindobonian Tethys received a uniform type of sedimentation. [NOT CONTROLLED OCR]

Une structure compressive au nord de l'Algérie?
Provedor de dados: 5
Autores: Auzende, Jean-marie; Olivet, Jean-louis; Bonnin, Jean.
From the study of continuous seismic reflection profiles (Flexotir) we have revealed a marked morphological contrast between the Northern Algerian margin and the other margins of the Balearic basin. Such a difference is made particularly clear by a downwarping of the sedimentary layers at the limit of the Algerian margin. This downwarping could be explained by the existence of a trench being formed by compression. [NOT CONTROLLED OCR]

Standard methods were used to assess the effectiveness of 101 products for use against oil slicks. Products were emulsifiers, agglomerants or precipitants and were tested against oil from Edjele, Kuwait and Syria. For each kind of product, a review is given of the previous tests, the choice of methods is discussed, the methodology is described, and results are presented and interpreted. In addition, the relationship between physical properties and effectiveness is discussed, with graphical examples and the advantages and disadvantages are indicated. It is concluded that at present no 'miracle' product exists for use in this field. Agglomerating powders would be ideal were it not for problems in putting them to use, and, wind because of the need to use them...

A taxonomic revision of Scolopia, based on the collections most important for the genus. Of the names of the about 80 taxa previously described in the genus, 28 remained valid; for 2 species and 1 variety a new combination had to be made, 7 new species and 1 new variety were added, and 5 species had to be transferred to other genera. This resulted in a total of 37 species (and 2 varieties); of these, 21 species are found in Africa (15 of them in Madagascar, the Comores, and the Mascarenes), 15 in Southeast Asia and Malesia (incl.

Terrestrial amphipoda collected in greenhouses in the Netherlands

Autores: Vader, W.
During the years 1942-1949 investigations were made on the fauna of the greenhouses of several Botanic Gardens in the Netherlands, on the initiative of Dr. A. D. J. Meeuse; material was also collected in greenhouses belonging to other institutions and in those kept for commercial purposes. A list of publications based on the results of these investigations has been given by Van der Hammen (1969). In a number of greenhouses the terrestrial amphipod, Talitroides alluaudi (Chevreux), was collected. This paper reviews the distribution of this species in Dutch greenhouses, and gives a survey of the occurrence of terrestrial species or the genus Talitroides in Europe. The genus Talitroides was erected by Bonnier (1898) for a species later named T. bonnieri by...

I (1788) 170, t. 34, and Beauvisage (1901) finally sank Ballardia in Metrosideros when he combined B. elegans Montr., Mem. Acad. Lyon 10 (1860) 205, with M. laurifolia var. minor Br. et Gris, Bull. Bot. Soc. Fr. 12 (1865) 300 under the binomial Metrosideros elegans. The group has remained in Metrosideros since that time. So far as is known the group is restricted to New Caledonia. The species may occur at quite low elevations, but are most common between about 300 and 1,500 metres altitude in forest or shrubland.

Decapoda and Decapod larvae in the surface plankton from the Southern North Sea near "Texel" lightship
Provedor de dados: 16
Autores: Baan, S.M. van der; Holthuis, L.B.; Schrieken, B.
INTRODUCTION From mid-January 1961 until the end of 1966 macroplankton was collected by the crew of "Texel" lightship (position: 53°01'30"Ν 04°22' E) and identified afterwards in the Nederlands Instituut voor Onderzoek der Zee, at that time still in Den Helder. The nets, of Saran gauze with a 2 mm mesh and an opening of 1 m2, were originally intended for catching elvers, for investigations reported upon by Creutzberg, 1961. The original aim of the present plankton project was to catch Scyphomedusae, but soon after it had been started all the available macroplankton was sorted out and, if possible, identified. This explains why the decapod larvae, dealt with in the present paper, came to be collected by nets, quite unfit for that purpose. When the meshes...

Factors influencing Artemia populations in Antillean salines
Provedor de dados: 16
Autores: Kristensen, Ingvar; Hulscher-Emeis, T. Marian.
In the Netherlands Antilles two extreme “forms” of Artemia salina, f. arietina and f. milhauseni, show all intermediate gradations. They hybridize constantly. When forma arietina is moved from lower concentrations into highly concentrated brine it will produce offspring that exhibit characteristics of the milhauseni form. The forms, therefore, do not represent groups of any systematical importance. Growth rate and body size show great variation. Often, greatest growth rate and largest size are found at salinities between 45 and 200‰. Below and above that concentration growth is usually stunted, and mortality is high. Artemia is not capable of getting rid of adhering silt. Moreover, silt seems to prevent the uptake of food. Artemia is oviparous at low...

Functional considerations and observations on the flowers of some Labiatae
Provedor de dados: 16
Autores: Pijl, L. van der.
The general bilabiate flower type or gullet-blossom was already recognized as functioning in diverse families by Delpino (lastly in 1887). The type seems adapted to hymenopters with precision of visits: not only by providing a lower lip as a favoured landing place with optical attraction and by ensuring co-ordination with the upper lip to limit visitor size, but also by providing precision of deposition and reception of pollen, viz. dorsally at the distal end. I add that the bifid stigma requires contact in the median plane, not from a side. This type of stigma may be considered as a consequence of the presence of two median carpels, but it also fits the ecological requirements extremely well. It also occurs in those Verbenaceae that show zygomorphy, but...

De Isopode Anilocra physodes (Linnaeus, 1758) voor de Nederlandse kust gevonden
Provedor de dados: 16
Autores: Holthuis, L.B.
Op 27 november 1964 werd door de trawler HD4 uit Den Helder bij de ST 2 boei in de zuidelijke Noordzee (53°33'N 4°02'E) een geparasiteerde zeekarper, Spondyliosoma cantharus (Gmelin), gevangen op een diepte van 33 m. De parasiet bleek een wijfje te zijn van Anilocra physodes (L.), een tot de familie der Cymothoidae behorende soort van pissebedden. Het dier had een totale lengte van 39 mm en was zodanig aan de kop van de zeekarper vastgehecht, dat de kop van de parasiet zich boven het linkeroog van zijn gastheer bevond. Door vriendelijke bemiddeling van de heer C. Swennen van het Nederlandse Instituut voor het Onderzoek der Zee te Texel (toen nog te Den Helder), werd de Isopode ter determinatie naar het Rijksmuseum van Natuurlijke Historie gezonden. Tevens...

Notes on New Guinea Rubiaceae. Versteegia and Maschalodesme
Provedor de dados: 16
Autores: Ridsdale, C.E.; Bakhuizen van den Brink, R.C.; Koek-Noorman, J.
Within the rain forests of New Guinea there are many small pachycaul treelets belonging to the Rubiaceae. Generally these are rare in occurrence and poorly represented in the herbarium, due in part to the problem of protecting rami- or cauliflorous flowers and fruits during routine processing and storage. All have a similar general appearance and are difficult to assign to a particular genus. Indeed, the generic limits and relationships of many have been in doubt since they were described and few have been re-investigated in light of more recent collections and ideas. Versteegia and Maschalodesme are two of the better known genera. These are considered from a taxonomic point of view together with notes on the wood anatomy and cuticular structures. The...

Short note on the occurrence of Cumacea in the surface plankton collected at "Texel" lightship in the Southern North Sea
Provedor de dados: 16
Autores: Baan, S.M. van der; Holthuis, L.B.
From mid-January 1961 until the end of 1966 macroplankton was collected in the surface water of the North Sea around "Texel" lightship (position: 53°01'3o"N 04°22'E). As pointed out in a recent paper on decapod larvae (Van der Baan, Holthuis &amp; Schrieken, 1972) the plankton nets were originally intended for collecting elvers and medusae, and the numbers of smaller species obtained, such as larvae and also Cumacea, was greatly influenced by incidental circumstances. Therefore no great significance can be attached to the actual numbers of these smaller animals. Cumacea are mostly bottom-dwelling species, and cannot regularly be expected in surface waters. Still, four species were found in our samples viz.: Diastylis bradyi Norman, 1879 Iphinoe trispinosa...

Color as related to Size, Sex, and Behavior in seven Caribbean Labrid Fish Species (genera Thalassoma, Halichoeres and Hemipteronotus)
Provedor de dados: 16
Autores: Roede, Machteld J.
Approximately 5500 Caribbean labrid fishes belonging to seven species were caught, transported, partly on ice, to the laboratory and subsequently studied. The major portion was examined immediately; some 20 per cent were stored briefly (less than three days) at minus 20°C. Color pattern (and shape of fins) may change during adult life, varying from slightly Halichoeres poeyi) to drastically Thalassoma bifasciatum). Per species a classification into successive color phases has been introduced; these color phases are strongly related to body length. In Halichoeres maculipinna, Hemipteronotus splendens and Hemipteronotus martinicensis females are restricted to the small, first adult color phase; males have exclusively been found in the larger intermediate and...

Autores: Jacobs, M.
In earlier papers attention was drawn to the fact that virtually all floras neglect the time of fruiting, and it was suggested that filling this gap in our knowledge would make a fine job for many an amateur botanist. The botanists DOING and GADELLA reacted with very elaborate suggestions, thus professionalizing the project and losing sight of the original aim: to get the fruiting times of plants into the floras. It is emphasized here again how much amateurs can contribute if they do not listen to perfectionists.

Range extension of Halophila stipulacea (Hydrocharitaceae) in the Mediterranean
Provedor de dados: 16
Autores: Hartog, C. den.
Halophila stipulacea (Forsk.) Aschers. is a sea-grass which is widely distributed along the coasts of the western Indian Ocean and the Red Sea. In 1895 Fritsch (Verh. Zool. Bot. Ges. Wien 45, 1895, p. 104) recorded the species from the Island of Rhodos in the Aegean Sea. This was the first record of the species from the Mediterranean. There can be no doubt that it penetrated the Mediterranean via the Suez Canal, which was completed in 1869. Although there are no early records of its occurrence in the Suez Canal, it is significant that it was the only sea-grass found during the exploration of the canal by Munro Fox in the autumn of 1924; at that time it was abundant in several localities in the canal.

Payen was a professional artist from the south of the then Netherlands (now Belgium) who toured for more than a decade in the Netherlands Indies (1817—1829)- His oil paintings and gouaches were made for a great deal in and around Bogor and also in Manado (Northeast Celebes). His main subjects were vegetation and landscapes, silhouettes of solitary, or groups of, trees, and a few more detailed paintings of individual plant species. His work is particularly beautiful and artistic. The State Museum of Ethnography at Leyden possesses several hundreds of paintings in three portfolios. A scanning learned that these paintings are not of any particular value for Malesian botany. Most of the plants depicted are common and mostly cultivated species: Gardenia...

A new species of toad, related with Bufo calamita Laurenti and B. viridis Laurenti, is described from the southern part of Morocco. Combining the data of the available specimens with literature records it was established that the new species probably ranges from the Sous valley southwards to Cape Bojador in the Spanish Sahara. The species seems to be restricted to semi-arid habitats. Tadpoles which probably belong to this species are described. Keys for the identification of adult toads and for the tadpoles are given.

Lizards with northern affinities from the mountains of Oman
Provedor de dados: 16
Autores: Arnold, E.N.
Oman material of four lizard species is described and discussed ; it comprises specimens of a previously undescribed gecko, Phyllodactylus gallagheri, two lacertids — the poorly known Lacerta jayakari Boulenger, 1887, and L. cyanura, also described here for the first time, and a skink, Ablepharus pannonicus Lichtenstein, 1823. These species have no strong affinities with any members of the mainly Saharo-Sindian fauna now occupying much of Arabia but are closely related to forms occurring to the north of the peninsula. It is probable that they are relicts of a more temperate fauna which once entered more extensively into southeastern Arabia. As might be expected, all four species are absent from the desert areas of Oman and are confined to the disjunct...

The herbarium collections of Odontoschisma denudation and O. sphagni from The Netherlands have been revised in connection with a study of the phenotypic variation and ecology of these species. In O. denudatum two natural modifications can be distinguished. Mod. pachyderma is more common and grows in young, open Erica-Calluna heath vegetation, on sandy ridges and rarely on tree trunks. Mod. mesoderma occurs in old, often N-exposed ( Erica-)Calluna heath vegetation on shaded substrates. O. sphagni is far more common than O. denudatum and morphologically less variable. It is a characteristic species of oligotrophic bogs and wet heath vegetation. Rarely O. sphagni grows on tree trunks or in rather dry heath vegetation together with O. denudatum mod. mesoderma....

The biology of the burrowing crab, Corystes cassivelaunus
Provedor de dados: 16
Autores: Hartnoll, R.G.
Corystes cassivelaunus (Brachyura, Corystidae), a crab which burrows in clean sublittoral sand, was investigated at several inshore locations around the Isle of Man. It usually buries itself so as to leave little or no external sign of its presence. Immature crabs remain buried by day throughout the year, as also do mature crabs except during the breeding season from April to June. It is probable that Corystes emerges nocturnally to forage over the surface of the sand. The morphology of the respiratory system, and the respiratory behavior patterns, are both modified on account of the burrowing habit. The food consists almost entirely of burrowing invertebrates, predominantly lamellibranchs, polychaetes and amphipods. There is a puberty-moult in each sex,...

Over het voorkomen van Sedum forsterianum Smith in Nederland
Provedor de dados: 16
Autores: Hart, H. ’t.
Recently Sedum forsterianum Sm. was excluded from the Dutch floras, because its occurrence in the Netherlands was doubted. This species, which resembles Sedum reflexum L. very much in habit, differs from the latter in the shape and attachment of the leaves on the non-flowering shoots and in the shape of the sepals and petals. Its stamens and carpels are smooth instead of papillate. In addition the two species have a different basic chromosome number. S. forsterianum occurs rather frequently in regions adjacent to the southern part of the Netherlands. In the last century it was also found in this country. The author is of the opinion that S. forsterianum might still be found in the Netherlands, and asks for reports of eventual finds.

Incidentally, ‘aguba’ is also the vernacular name used by Roxburgh in his Flora Indica and this manuscript name was used only by Roxburgh before he described the species as Capparis corymbosa.

The monogeneric family is placed in the Rhamnales in the system of ENGLER and is closely allied to the Vitaceae, sometimes considered as a subfamily or tribe of that family. Distinguished from the Vitaceae by the development of a complex staminodial tube, by the presence of one ovule in each locule of the ovary. Pollen is also distinct from that in Vitaceae, supporting the segregation into a separate family. Seed and embryo features and the presence of pearl glands on the vegetative organs indicate a very close affinity with the Vitaceae but not to other families.

Hydroids from submarine cliffs near Arthur Harbour, Palmer Archipelago, Antarctica
Provedor de dados: 16
Autores: Vervoort, W.
At the instigation of Dr. Joel W. Hedgpeth, Resident Director, Marine Science Center, Oregon State University, Newport, Oregon, U.S.A., I studied samples of hydroids, collected by Dr. John C. McCain and Dr. William E. Stout from submarine cliffs in the region around Palmer Station, Antarctica. The hydroids had been obtained during an examination of the zonation of rocky substrates in that area in the austral summer of 1968-1969. During this survey 0.25 m2 samples were scraped from the rocks at 5 feet intervals down to a depth of 50 feet and at 10 feet intervals from 50 to 100 feet. Dr. McCain and Dr. Stout were able to complete one such transect and a portion of another (Hedgpeth, in litt., see also McCain &amp; Stout, 1969). The bulk of the material on...

The wood anatomy of Gardenieae, Ixoreae and Mussaendeae (Rubiaceae)
Provedor de dados: 16
Autores: Koek-Noorman, Jifke.
The tribe Gardenieae in the restricted delimitation proposed by Bremekamp and Verdcourt is wood anatomically homogeneous. The genera of the Ixoreae studied by me also agree with each other in wood structure. Within the tribe Mussaendeae in the delimitation accepted by Schumann the wood anatomy shows much variation. The tribe becomes more homogeneous, if some of the genera included in this tribe by Schumann are removed. The systematic position of some genera, which in the literature are said to be related to Gardenieae, Ixoreae or Mussaendeae, is discussed in the light of similarities and differences in the wood anatomy.

The lizards of the Anolis equestris complex in Cuba
Provedor de dados: 16
Autores: Schwartz, Albert; Garrido, Orlando H.
Anolis equestris Merrem, the Cuban giant anole, was described in 1820. The formal description is based upon an account of the lizard by CUVIER (“le grand Anolis a crête”) in 1817. MERREM’S description is very brief but sufficiently detailed to assign the name to the Cuban species rather than to any other Antillean giant anole. The lizard was redescribed by BELL (1827) as Anolius [sic] rhodolaemus, based upon material collected by W. S. MACLEAY. NOBLE &amp; HASSLER (1935) named Anolis luteogularis from a long series from western Cuba. This species was relegated to subspecific status under A. equestris by BARBOUR &amp; SHREVE (1935), who also named A. e. hassleri from the Isla de Pinos (based upon two specimens) and A. e. noblei from eastern Cuba (based upon...

New data on southern African Achatinidae (Mollusca, Gastropoda Pulmonata)
Provedor de dados: 16
Autores: Bruggen, A.C. van.
Increasing knowledge of the genital anatomy of the species of the African land snail family Achatinidae has greatly improved our understanding of the delimitation of the species and the intricate interrelationships of the various taxa (Mead, 1950). The genitalia of many achatinids are still unknown due to the absence of properly preserved animals. New data, mainly on the reproductive organs of recently collected material, are supplied here for two Southern African species, Archachatina sandgroundi Bequaert and A. dimidiata (Smith), which have now been dissected for the first time. Acknowledgements are due to Mr. J. F. Peake and his staff at the British Museum (Natural History), London, Prof. K. J. Boss of the Museum of Comparative Zoology at Harvard...

Reaping the harvest. Retrieval of names and identifications by means of identification and collection lists
Provedor de dados: 16
Autores: Steenis, C.G.G.J. van.
Among past acquisitions of the larger herbaria there are frequently duplicate collections which at the time of the distribution of the sets were not or very inadequately named. Examples of some famous large collections which were handled this way are those of Beccari, Forbes, Sieber, Dietrich, Zenker and others. They were either unnamed or only provisionally named with pre-identifications in approximate degree of accuracy to family and sometimes to genus. As a matter of fact, this is for large collections still current procedure as it would create an impossible situation to have all such bulky collections shelved as a whole for some decades, or even many decades and postpone distribution of sets until all numbers are named by specialists.

Autores: Gradstein, S.R.; Melick, H. van.
First record of Bryum gemmiparum de Not. from The Netherlands. The taxonomy and distribution of the species are discussed. Bryum gemmiparum was collected in a clay-pit along the river Maas in the north of the province of Limburg. This locality seems to be the northernmost one known of the species. Bryum gemmiparum was found growing on steep, rather humid, loamy soils in a luxuriant cover of bryophytes characterized by Anisothecium varium, Riccardia sinuata, Riccardia pinguis, Bryum bicolor, Didymodon tophaceus, and Mniobryum wahlenbergii. A floristical and ecological investigation of this highly interesting bryophyte vegetation in The Netherlands is needed.

Diese Publikation ist Herrn Prof. Dr. L. D. Brongersma gewidmet. Obwohl sich zahlreiche Wissenschaftler mit der Tier- und Pflanzenwelt des süd- und zentralamerikanischen Raumes beschäftigten, sind wir noch weit von einem Verständnis seiner Biogeographie entfernt. Die Ursache hierfür liegt nur zum Teil darin, daß „die in der gemäßigten Zone lebenden und arbeitenden Populationsbiologen Studien in tropischen Gegenden kostspielig und schwierig finden" (MacArthur &amp; Connell, 1970). Der tiefere Grund ist der ungeheure Pflanzen- und Tierreichtum einzelner Lebensräume dieses Kontinents.

Pacific capsular Myrtaceae 4. The Metrosideros Complex: Xanthostemon, Nani, Pleurocalyptus, Purpureostemon
Provedor de dados: 16
Autores: Dawson, J.W.
The four closely related taxa considered in this paper have all been referred to Metrosideros at some time. Nani Adanson is still generally treated as a section of Metrosideros Banks ex Gaertn. (nom. cons.) despite the objections of several earlier authors (Merrill, 1952; Rock, 1917; Valeton, 1901; Miquel, 1885). A comparison of the description of Nani in the present paper with that of typical Metrosideros (Dawson, 1970) shows that the two genera differ widely in many features. I agree with Merrill (1952) that the affinities of Nani he with Xanthostemon and further suggest that a detailed revision at the specific level may lead to their being merged. If such a merger takes place, then Nani would have priority over Xanthostemon, although a strong case for...

In addition to the papers of HILLEGERS (1969), LONDO (1969), and WEEDA (1970) on the occurrence of Gagea lutea in the Netherlands, a description is given of the only known locality of this species at Hertsberge (prov. West Vlaanderen, Belgium) in the Flanders District. Gagea lutea, Ranunculus ficaria, R. auricomus, Anemone nemorosa, and Primula elatior are the only woodland species which have remained after the original wood was laid down to grass in 1953. The vegetation now belongs to the Agropyro repentis-Aegopodietum podagrariae. A relevé is given of a nearby Alno-Ulmion wood of the Aegopodio—Fraxinetum which very probably resembles the situation before 1953.

The Crustacea Decapoda Macrura (the Alpheidae excepted) of Easter Island
Provedor de dados: 16

So far the Crustacean fauna of Easter Island has received but very little attention. In most early narratives of expeditions visiting the island no mention is made of any Crustacean. Behrens (1908: 135) who accompanied Jacob Roggeveen on the voyage during which, in 1722, the island was discovered, stated in his diary that "No animals were met with, as far as we penetrated on this occasion, except sundry species of birds". Cornelis Bouman, captain of the ship "Tienhoven" of Roggeveen's expedition, did not mention any Crustacean from Easter Island, even though in his narrative he shows a great interest in marine life, as is clearly demonstrated by his account of the expedition's visit to Juan Fernandez (24 February to 17 March 1722) in which he repeatedly...

A computer-based registration system for geological collections

Autores: Germeraad, J.H.; Freudenthal, M.; Boogaard, M. van den; Arps, C.E.S.
The new computer-based registration system, a project of the National Museum of Geology and Mineralogy in the Netherlands, will considerably increase the accessibility of the Museum collection. This greater access is realized by computerisation of the data in great detail, so that an almost unlimited number of operations to select and sort the data is possible. A flexible design of annotating information, mainly in plain words, saves considerable time. The fast mechanical data processing permits the efficient preparation of catalogues which contain selected information about the geological collection; as an additional benefit labels may be produced at low costs. The RGM system disposes of the burden of classical registration books and card-indexes, without...

The construction for feeding in Rattlesnakes
Provedor de dados: 16
Autores: Dullemeijer, P.; Povel, G.D.E.
INTRODUCTION A controversial point in the understanding of the feeding mechanism of viperid snakes is the use of the poison fang in the swallowing mechanism. Some authors believe that the poison fang takes an active part in the swallowing act, although the majority supports the view that the fang is, at least partly, held down (Klauber, 1956). Which kind of construction in the jaws is responsible for the difference between the actions of the fang in striking and swallowing again is a matter of dispute. The pterygoid-ectopterygoid joint, which by most authors (Kathariner, 1900; Willson, 1908; Haas, 1931; Klauber, 1939, 1956) is considered stiff or immovable, may play a crucial role. There is also some disagreement on the strike being either a stab (Van...

Several pieces of fossil wood have been analyzed with X-ray diffraction and were grouped on the basis of mineralogical composition. Various mineralizations were studied in thin sections and by means of the scanning electron microscope. Wood-opals appear to show a structure preservation that points to replacement of cell walls by silica. The wood-opals are mineralogically characterized as 'disordered tridymite'. Other mineralizations, such as chalcedony, quartz, carbonates, phosphates and iron-oxydes and -hydroxydes show characteristics of filling-in. Various mineralization processes are discussed.

A beautifully preserved fragment of the test of a fossil Echinoid from the Maestrichtian Cretaceous, found at Belvédère, Caberg and kept in the Natuurhistorisch Museum, Maastricht under no. 1340, differs from the other species of the genus Phymosoma, hitherto described (cf. Fell &amp; Pawson, 1966: U 395). It is a great pleasure to dedicate the description of this obviously new species to my friend and colleague Leo Brongersma in remembrance of the many and wide contacts we enjoyed since I tried and initiated him into the secrets of zoological museumwork, while as a student he occupied an ever increasing space in my room at the Zoological Museum of Amsterdam University. The fragment of this Phymosoma includes an ambulacrum and an interambulacrum and...

Precursor to a taxonomic revision of Ceylon Dipterocarpaceae
Provedor de dados: 16
Autores: Ashton, P.S.
The taxonomy of the largely endemic dipterocarp flora of Ceylon is brought into line with that of the rest of the Asiatic subfamily, and a new species is described. Stemonoporus lewisianus Trimen ex Hook. f. finds its correct place at last in Cotylelobium. Balanocarpus brevipetiolaris (Thw.) Alston is transferred to Hopea. Shorea pallescens Ashton (sect., subsect., Shoreae) is described for the first time. Shorea stipularis Thw. is ascribed to sect. Anthoshorea Heim. Doona Thw. is reduced, as a separate section, to Shorea Roxb. ex Gaertn.f., necessitating 7 new combinations and 3 new names. Doona oblonga Thw. is united with Doona disticha (Thw.) Pierre under the name Shorea disticha (Thw.) Ashton. Doona nervosa Thw. is reduced to Doona cordifolia Thw., now...

Observations on Sporophyte Development in Odontoschisma prostratum (Hepaticae)
Provedor de dados: 16
Autores: Gradstein, S. Rob.
Anatomical study of developmental stages of the sporophyte of living Odontoschisma prostratum (Sw.) Trev. revealed that the conspicuous swelling of the female branch during sporophyte development is correlated with a remarkably strong growth of the sporophyte foot. Thus, the enlargement of the female branch must not be looked upon as a “perigynium precursor.” The anatomy of the seta supplies new evidence for a close taxonomic relationship between Odontoschisma Dum. and Cladopodiella Buch.

Note on the chemotaxonomy of Huaceae

A comparative study of acetone, ethanol, and hydrolysis extracts of Hua gahonii Pierre ( Bos 6677, leaves) and Afrostyrax lepidophyllus Mildbr. (Brookman Amissah s.n., bark) has been carried out. The presence of the following compounds could not be demonstrated: gallic acid, ellagic acid, leucoanthocyanins, catechin, arbutin, hydroquinone, and bergenin. As these compounds occur rarely or are absent in the Bombacaceae and Sterculiaceae, their seeming absence in the Huaceae suggests the possibility of a relationship between these families.

Langs een pad, dat ca. 15 jaar geleden gemaakt werd door het struweel van Rosa rubiginosa, Ligustrum vulgare en Hippophaë rhamnoides, werden door de heer R. Ram (Pernis) tijdens een excursie twee mooie exemplaren gevonden, die in het najaar, samen met een zaailing zijn teruggekomen.

A new scincid lizard of the genus Leiolopisma from New Guinea
Provedor de dados: 16
Autores: Zweifel, R.G.
The lizard fauna of New Guinea numbers over 150 species (for a list, now well out-dated, see Loveridge, 1948), and probably more than two-thirds of these belong to the family Scincidae. With the exception of studies by Brown (1953, 1954) on the genus Emoia, the large and diverse scincid fauna has received little attention from herpetologists since De Rooij (1915) summarized existing knowledge. The validity of many named forms is questionable, and details of distribution and ecology are known for virtually none. The purpose of the present paper is to describe an evidently unnamed species that has been confused with a widespread Papuan species, Leiolopisma miotis.

The Paradoxosomatidae of the Fiji Islands are discussed. As a result of the reexamination of the type material the taxonomic position of Orthomorpha lampra Chamberlin and Prionopeltis dasys Chamberlin is cleared. O. lampra is a senior synonym of Gyrodrepanum bimontanum (Carl), P. dasys a junior synonym of Anoplodesmus saussurii (Humbert). All the known paradoxosomatid species of the Fiji Islands are introduced from elsewhere, mostly from India.

Dutch material of Ornithogalum umbellatum L. sensu lato was cytologically investigated. Two cytotypes appeared to occur, with the chromosome numbers 2n = 27 and 2n = 54. A description of the triploid and hexaploid plants is given. The triploids should be assigned to O. umbellatum, the hexaploids may be assigned provisionally to O. divergens Bor. The taxonomic status of the latter species is discussed. Further research is required for the solution of the taxonomic problems.

This paper is dedicated to Prof. Dr. L. D. Brongersma on the occasion of his 65th birthday. During several collecting expeditions of later years by this museum to the former Dutch New Guinea, organized and directed by Dr. L. D. Brongersma, a considerable number of Microlepidoptera has been collected upon my request. Among these a special place occupy the Schoenoteninae, a characteristic group of the Tortricidae, chiefly confined to New Guinea and Australia. The somewhat turbulent history of the Schoenoteninae has been aptly summarized by I. F. B. Common (1965). The definitive assignment of the subfamily has been much hampered, chiefly by the three following features: (1) the isolated position of the present group, as compared with other subfamilies of the...

Notes on the identification and speciation of Heteropoda (Gastropoda)
Provedor de dados: 16
Autores: Spoel, S. van der.
INTRODUCTION Specimens of Heteropoda, especially of Atlantidae, which are damaged by the nets and have lost their shells by the action of preservatives are usually considered to be hardly identifiable. Tokioka (1961) used the opercula as a new source of morphological information for the study of the shell-less Atlantidae. The laborious preparation of opercula enables only the identification of some species. The occurrence of groups of closely related taxa showing only slight morphological differences is responsible for other difficulties in identification. Recent expeditions, like the Cicar Expedition, the Eastropac Expeditions and the Acre project provided samples with large quantities of damaged heteropods, which induced me to look for a simple method to...

Autores: Nooteboom, H.P.
This work is the first of its kind in so far that it gives an account of the chemotaxonomy of a large family of plants and its implications on the taxonomy of that family. The ideas for this book were derived from a symposium, to which all the 19 authors contributed, ‘The Comparative Biochemistry of the Leguminosae’, which was held at the John Innes Institute, Hertfordshire. The first chapter, by V. H. Heywood, gives a ‘Systematic Purview’ of the family. Chapter 2—14 provide a description of the known distribution of both low molecular weight and macromolecular constituents. In several chapters the methods used are also extensively discussed. Often the information of the various chapters has been obtained by workers belonging to other disciplines than...

Pollen morphological evidence for subdivision and affinities of Lecythidaceae
Provedor de dados: 16
Autores: Muller, Jan.
A subdivision of the pollen types encountered in Lecythidaceae is proposed. The presence of a demarcation line between an original colpate and a derived syncolpate pollen type is confirmed. The significance of pollen characters for taxonomic subdivision is evaluated and it is concluded that the subdivision proposed by Niedenzu in 1892 agrees best with the pollen evidence. Pollen morphology does not yet provide any clear indications of wider affinities of the family, except in a negative sense.

According to Beauvisage (1901), the same species was included by Brongniart and Gris, Bull. Soc. Bot. Fr. 10, (1863, 576), in their genus Cloezia, and this will become the valid name for the genus if it is ruled that Montrouzier’s name is an orthographic variant of Moorea Lemaire, Ill. Hort. 2 (1855) Misc. 14. The genus is probably restricted to New Caledonia, where about eight species occur in shrub associations from near sea level to about 700 metres.

Autores: Chew, Wee-Lek.
Recently, while going through the old collections of Malesian, Australian, and Pacific materials of Piperaceae in connection with the study of the New Guinea species of this family, taxonomic problems that need clearing up were encountered. These are of such a diverse nature that it is best they are discussed separately in each species and not summarized here. This paper is the first of many which will be published seriatim as work on this difficult group progresses. As implied in the title, this series does not deal with New Guinea species which are the subject matter of another series. It is hoped that these contributions will pave the way for a comprehensive revision of the family in Malesia in which more than 400 species have been described or recorded.

Though I highly appreciate this work in general, and the clear way in which the differences between forms are exposed, I must lodge an objection as to the way the analysis of the genera is exposed. In Scudder's "Key to genera in the Astacops complex" hardly any of the characters used by the authors of the genera is mentioned; most characters are invented by Scudder. I don't think this to be a useful manner. Of course it can be of...

About twenty years ago MARTÍNEZ proposed some new genera for the accommodation of a number of aberrant South American aphodiid beetles, until then placed in Euparia LePeletier &amp; Serville. In 1951 he referred two species, Euparia costulata Harold and E. ovalis A. Schmidt, to his genus Lomanoxia, recognizable i.a. by having the sides of the elytra acutely inflexed. As these scarabs are exceedingly rare in collections, I was delighted at finding specimens referable to Lomanoxia among some material collected from the nests of leafcutting ants in Surinam; one represents a species new to science. My unsuccessful efforts to trace the type of Euparia costulata Harold in the Paris museum were compensated by the recovery of additional specimens of Lomanoxia, one...

New data on the ostracode genera Laocoonella de Vos &amp; Stock, Redekea de Vos, and Aspidoconcha de Vos; with a key to the family Xestoleberididae and a resume of symbiosis in Ostracoda
Provedor de dados: 16
Autores: McKenzie, K.G.
Investigation of the commensal genus Aspidoconcha de Vos indicates that it belongs in the family Xestoleberididae. Relationships of the commensal Redekea de Vos are uncertain. The genus Laocoonella de Vos &amp; Stock is referred tentatively to family Cytheruridae. Among Ostracoda, symbiosis is more common than was previously realised; the possible occurrence of intra-Ostracoda symbiosis is reported.

Polyzygia Guerich (Ostracoda) in the Devonian of Asturias and Leon (Spain)
Provedor de dados: 16
Autores: Michel, M.Ph.
The Devonian ostracode genus Polyzygia Gürich has been defined anew and its systematical position has been revaluated. It is considered as a thlipsurid (bas-relief sculpture) metacope (tripartite hinge, contact groove). Eight species (one new, one with open nomenclature) and two subspecies are described, all from the Devonian of the central part of the Cantabrian Mountains, provinces of Asturias and León, Spain. The existence of pores and of a micro-scale reticulation is established. An opinion is given concerning the calcification of the valves, and the known geographical and stratigraphical distribution is discussed.

Facies and diagenesis of the Devonian Portilla limestone formation between the river Esla and the Embalse de la Luna, Cantabrian Mountains, Spain
Provedor de dados: 16
Autores: Reijers, T.J.A.
In the central part of the Cantabrian Mountains, between the artificial lake in the rivei Luna in the west and the river Esla in the east, outcrops of the Portilla Limestone Formation were investigated. A fairly uniform development could be observed in four structurally different areas. Six lithostratigraphic units: four members and two beds, were recognized and correlations were established on the basis of lithostratigraphic characteristics. In these units six facies types could be distinguished. Lithological samples, characteristic of the facies types, served as a basis for the investigation of the diagenetic products and processes, especially the early diagenetic ones. Mainly in view of differences in lithofacies, and of the presence of biogenetic...

Systematics and ecology of New Caledonian Faviinae (Coelenterata – Scleractinia)
Provedor de dados: 16
Autores: Wijsman-Best, Maya.
Taxonomic treatment of a large collection of recent corals from New Caledonia belonging to the subfamily Faviinae resulted in the full description of thirty-four species amongst which two are new, while some others are briefly mentioned. A pattern for the subfamily in the influence of environmental factors on growth was found. A comparison between this general pattern and the environment-induced modification of each different form allowed a particular growth form’s ecology to be used as a criterion for defining the species to which it should be allocated.

Autores: Krijnen, J.P.
In the present paper, certain morphological features and the ontogenetical development of members of the subfamily Pseudorbitoidinae Rutten, 1935 are discussed. A study of the evolution of Pseudorbitoides Douvillé, 1922 resulted in testing the concept of nepionic reduction in populations of this genus from Jamaica (Green Island- and Sunderland Inlier) and Curaçao (Cas Abao Limestone lenses). Within the Pseudorbitoides-lineage, P. trechmanni pectinata subsp. nov. is distinguished from P. trechmanni trechmanni Douvillé on account of different post-juvenile features.

The status and relationships of some East African Earless Toads (Anura, Bufonidae) with a description of a new species
Provedor de dados: 16
Autores: Grandison, A.G.C.
INTRODUCTION In comparing some small Ethiopian Bufo with the descriptions, types and other examples of numerous forms from East and Central African countries I became very much aware of the confusion that exists in the taxonomy and of the need for a revision of this group of dwarf toads. Most of the earless East African toads have received little or no attention since Loveridge's papers in the 1930s and a bewildering assortment of characters of doubtful taxonomic value have been used. Two of the most misleading terms applied to these small toads are "tympanum hidden" and "paratoid obscure". Often preservation alone has rendered the outline of the tympanic annulus and the paratoid obscure or invisible and only dissection reveals the true extent of the...

Simplistrigilla in the western Atlantic Ocean (Mollusca, Bivalvia)
Provedor de dados: 16
Autores: Boss, K.J.
In a recent monograph on the tellinid genus Strigilla, the absence of a representative of the subgenus Simplistrigilla was noted in the Western Atlantic region (Boss, 1969). Simplistrigilla was described by Olsson (1961) with the species S. strata Olsson, 1961, as type. The species is rare with a considerable range in the Panamic Province of the eastern Pacific Ocean, occurring from El Lagartillo, Panama, southward to Punta Blanca, Ecuador. The unusual feature possessed by this species is in the nature of the scissulae or oblique incised lines which descend across the shell from the anterior dorsal margin toward the ventral and posterior margins. In S. strata these scissulations do not change direction or form a complex of flexures along the posterior...

The occurrence of the skull parasite Skrjabingylus nasicola (Leuckart, 1842) in Stoats and Weasels from the Netherlands has been studied extensively. A redescription is given of certain morphological characters of the parasite, which includes the discovery of hitherto unknown peribuccal papillae. The genus Skrjabingylus is discussed. The extent of infection and the damage caused by the parasite in Stoats and Weasels has been assessed by studying collections of preserved skulls. Detailed comparisons are made between the infection percentages in both species of mustelids in different areas of the Netherlands and in different European countries. Also the relation between infection and age and sex has been studied. In the discussion an attempt is made to...

Priapulus from the deep sea (Vermes, Priapulida)
Provedor de dados: 16
Autores: Land, J. van der.
INTRODUCTION The species of the genus Priapulus occur in rather cold water. Hence, their shallow-water distribution is restricted to northern and southern waters (fig. 1); there are only a few isolated records from sub-tropical localities. However, in deep water the genus apparently has a world-wide distribution (fig. 2). The northern species (P. caudatus De Lamarck) and the southern species (P. tuberculatospinosus Baird) from shallow water are well defined but the specimens from the deep sea present systematical problems. In my survey of the Priapulida (Van der Land, 1970) I could not answer the question of their identity, because I had seen only very few specimens from deep water and not a single one from the tropical deep sea. Meanwhile I could study...

Studies in the New World Sapindaceae I. Notes on the genus Talisia aublet

Autores: Kramer, K.U.
Since the completion of Radlkofer’s monumental work on the Sapindaceae in Engler’s series “Das Pflanzenreich” 50 years have now elapsed, almost 40 since its publication. It is still the basis of virtually all taxonomic studies in the family. Some of the gerontogean genera have since been the subject of revisional work (Leenhouts 1969, 1971), but for the neogean representatives there are only some regional treatments (e.g. Rambo 1952; Barkley 1957; Reitz 1962; Soukup 1969), apart from descriptions of new taxa scattered through the literature. When studying the taxa native to Suriname in connection with the preparation of a supplement to the family treatment published previously in the “Flora of Suriname” (Uittien 1937) it soon became apparent to me that the...

Three members are informally distinguished in this formation (A, B, and C from base to top). They are present at the western part of the outcrop (thickness ca. 246 m). On the eastern and southeastern part, only member A and basal part of member B are present and the thickness is reduced to ca. 20 m. A sharp surface of discontinuity separates member A from member B. The Portilla Formation abounds in reef-building elements associated with other groups. Five major carbonate facies types are established that belong to a complex biostromal ‘reef’ facies. Vertical and lateral facies changes are demonstrated. The carbonate facies was deposited in a shallow-marine environment. Towards end of deposition of member A, sharp changes in depositional conditions...

Of fourteen populations of Molinia caerulea (L.) Moench from a variety of habitats in the Netherlands, the morphological variability was studied. It appeared that most of the recorded characters have a normal statistical distribution and that the ranges of variance overlap one another appreciably. It was impossible to distinguish infraspecific taxa of Molinia; this is in contradiction to the treatment of the species in Flora Neerlandica (JANSEN, 1951). Chromosome counts made of plants of the 14 localities consistently yielded the same number, viz. 2n = 36.

Fluvial sediments of Cretaceous Age along the southern border of the Cantabrian Mountains, Spain
Provedor de dados: 16
Autores: Jonker, Rob.K.
This study deals with a sedimentological description and interpretation of a strip of continental deposits of Cretaceous age along the southern border of the Cantabrian Mountains. In this work they are designated as Voznuevo Formation (Evers, 1967). They belong to the type of deposits which have commonly been referred to as ‘sediments in Wealden facies’. As regards stratigraphy, palynological analyses (apart from pollen, the Voznuevo Formation proved completely barren) made it clear that the transition between the Lower Cretaceous and the Upper Cretaceous runs obliquely through the formation. Hence, the Voznuevo sediments are diachronic deposits, decreasing in age in a westerly direction and forming the continental counterparts of successively younger...

Autores: Nagtegaal, P.J.C.
An ordered sequence of well-defined sedimentary environments reflects the deepening and shallowing stages in the depositional history of the Upper Cretaceous basin in the South-Central Pyrenees, Spain. The sequence, which has a Santonian age at its base, starts with a calcarenite barrier system on which occurs a coral reef showing well-differentiated fore- and back-reef facies (Congost Limestone Formation). Marked deepening of the basin occurred during the deposition of the overlying glauconitic nodular limestones, as is evidenced by a predominantly planktonic fauna, consistent fine grain size, a very large planar slump scar, and frequent other slump structures (Anserola Formation). Sedimentation continued in a deep marine, carbonate turbidite facies...

Secondary chamberlets in Cycloclypeus
Provedor de dados: 16
Autores: O'Herne, L.
Graphs, showing the relation of the primary chambers to the number of their secondary chamberlets, demonstrate that Tan's nepionic mutants are variable, even in the course of a short period. The evolutionary change of the nepionic mutants is consistent with the evolutionary change of Cycloclypeus as a whole. The number of secondary chamberlets of the first neanic chamber is considered a valuable characteristic for the identification of species. Reduction of the number of nepionic chambers in the course of time is thought to result from the occurrence of 'transitional nepionic variants'.

The pollen-collecting activities of some andrenid bees
Provedor de dados: 16
Autores: Dingemans-Bakels, F.N.
Information about the pollen-collecting activities of bees is usually based on field observations. From such records it cannot be inferred whether pollen was actually collected, as bees, especially the males, also may visit flowers to suck honey or to rest. One may expect more exact data from an analysis of the pollen actually carried by the bees. This paper deals with a study on bees of the genus Andrena. Some species of this genus are supposed to be oligolectic. Pollen loads were taken from preserved collection specimens and the pollen was prepared following the usual methods for the study of recent pollen. In the greater part of the samples taken one type of pollen proved to be dominant. Apparently a bee tends to visit only one species of flower per...

Donk as a tribute to his life-long endeavour to put the systematics and the taxonomy of this challenging order on a sound basis. A collection of South Asian specimens of Ganoderma and various other collections have been studied taxonomically as to spore, pore and anatomical cutis characters by using a technique devised by the author (Steyaert, 1946: 137; 1947: 47); it allows microtome sections of botanical material to be mounted immediately in Canada balsam. Three genera and 15 of the 39 species studied are described as new. All species are from Indonesia except when indicated otherwise; they are Humphreya, Haddowia, Magoderna, and Ganoderma kosteri (The Netherlands), G....

The spelling of the name Sarothrogammarus (Crustacea, Amphipoda)
Provedor de dados: 16
Autores: Stock, Jan H.
In my recent revision of the Sarothrogammarus-group (Bijdr. Dierk., 41: 94—129, 1971), I consistently used the spelling Sarathrogammarus. Professor S. Ruffo, of Verona, kindly pointed out to me that the original spelling of the name is Sarothrogammarus (see Martynov, 1935, Trav. Inst. zool. Acad. Sei. URSS. 2: 484—506). Though the etymology of the word is not very clear (perhaps from σαρω = to brush, to clean), it is evident that there are no good grounds for the spelling Sarathrogammarus, as used by me.

De Kleine Koornaarvis, Atherina mochon Valenciennes, 1835, in Nederland (Pisces, Atherinidae)

Reeds enkele auteurs (Schrieken &amp; Swennen, 1969; Vaas, 1970) hebben het voorkomen van Atherina mochon in Nederland geconstateerd. Zij vermeldden de soort uit het Veerse Meer, waar deze al in 1964 werd gevangen. Geen van deze auteurs gaat echter in op de vraag, hoe deze soort waarvan de verspreiding in hoofdzaak Mediterraan is, in het Veerse Meer gekomen is. Tijdens bezoeken aan de binnenhaven van Vlissingen, waar de electriciteitscentrale (PZEM) zijn brakke koelwater loost, bleken grote scholen van Atherina mochon aanwezig te zijn naast scholen van de gewone koornaarvis, Atherina presbyter Valenciennes, 1835.

Dr. J.A.R. Anderson, Kuching, was on leave in spring 1971; he would return in the middle of the year for a final short tour. Dr. Anderson’s merits for the development of Botany in Sarawak are extremely large; it is a great pity to see such most experienced personalities leave the scene. We are thankful for his important endeavours and wish him a happy retirement. Prof. Dr. C.D.K. Cook, Zürich, is preparing a manual for the identification of aquatic plants.

The completion of the seventh volume of this Flora gives me the occasion to dedicate this volume to HERMAN JOHANNES LAM, who from the beginning was intimately connected with the taxonomical study of the flora of the Malesian region, adopted the working team, provided for it a permanent niche in his institute, and finally played an important role when the perpetuating of its existence was threatened in 1958. HERMAN LAM was born in Veendam, January 3rd, 1892. His father was an organic chemist and taught chemistry at Veendam. There was a possibility that he would be attached to the University at Groningen, but he accepted a new post in Rotterdam, in 1893, to set up the first municipal food-inspection department in Holland; this stood model for such...

Observations on eggs of eublepharid lizards, with comments on the evolution of the Gekkonoidea
Provedor de dados: 16
Autores: Werner, Y.L.
Captive specimens of Coleonyx v. variegatus, C. v. bogerti, Eublepharis macularius and Hemitheconyx caudicinctus laid parchment-shelled, moisture dependent eggs, resembling those of diplodactyline geckos and most lepidosaurians. Eublepharid eggs, including those of Aeluroscalabotes measured in radiographs, are twice as long as broad. Supporting and complementary evidence in the literature is considered. It is concluded that the Eublepharidae are a monophyletic group of the Gekkonoidea, retaining the primitive egg type. Functional and evolutionary aspects of various characteristics of different gekkonoid eggs are discussed, and conclusions drawn.

Annales des Sciences Naturelles, Sér. 5, Botanique. Cf. Wood ex Tennant, Kew Bull. 16 (1963) 410-411. From the dates reproduced it is seen that part 1 was billed in November 1868; it is assumed that this puts the publication date of the whole volume after that of vol. 1 of ’The Flora of Tropical Africa’. Forster, J.R. &amp; Forster, J.G.A., Characteres generum plantarum, etc. 1st ed. 1775. Folio. Cf. Harold St. John, Natur.Canad. 98 (1971) 561-581. The well-known quarto edition 1776 has been found to have been issued on March 1, 1776; another edition, also dated 1776, was printed in long folio format, and seems to have existed of 8 copies (elsewhere recorded 25 copies).

A new species of Gynothemis and its larva (Odonata, Libellulidae) notes on Odonata of Surinam XII
Provedor de dados: 16
Autores: Geijskes, D.C.
The genus Gynothemis was introduced by Calvert (1909), when describing an aberrant member of the Macrothemini from Brazil. The following characteristics were used for this genus: anal area in hind wing with irregularly arranged cells; one row of cells in Rspl, M2 not undulate; triangle in fore wing free, two rows of cells in discoidal field from triangle to wing margin. Femora in both sexes armed with the usual two rows of spines, those of the male not differentiated. Type species: Gynothemis venipunctata Calvert, from Chapada in Brazil. Ris (1913) added two more species to the genus, viz., heteronycha Calvert, described by the author in Brechmorhoga, and calliste Ris, known from one female only. According to Ris, the three species resemble the smaller...

Autores: Rooij-Schuiling, L.A. de.
In 1959, Mr. A. Hoogerwerf obtained a number of small Mollusca from the gizzard of a godwit (Limosa spec.) shot near Koerik, West Irian, New Guinea, that eventually came into my hands for identification. Though the specimens clearly belonged to a species of the genus Mesodesma (Mactracea, fam. Mesodesmatidae), further identification with any of the known species of this family proved to be impossible. This stimulated me to revise the Mesodesmatidae. During this revision many species were encountered, that had each been described under several different names. New synonymies in the genera Ervilia Turton, 1822, and Coecella 1) Gray, 1853, will be dealt with in the present paper. Diagnosis of the Mesodesmatidae. Shell equivalved, small to moderately large...

Gebiete Naturw. Hamburg 18, 1903, 53). About the same time LANG argued (Flora 88, 1901, 179) that on morphological and anatomical grounds Byblis cannot belong to Droseraceae, but should be referred to Lentibulariaceae. DIELS (Pfl. R.

The present article is the first of a series in which a new classification of the reed swamp and marsh communities (order Phragmitetalia, class Phragmitetea) in the Netherlands (in WESTHOFF &amp; DEN HELD, 1969) will be tested. The material used consists of the sample-plot analyses recorded by the Foundation for Biocenological Research (SOL) in the years 1954-1956 along former river beds in the forelands of the great rivers. Therefore, the test implies a partial re-evaluation of the results of that study as presented by VAN DONSELAAR (1961). The first community treated, the association Scirpetum lacustris (alliance Phragmition), most of which was formerly included in the Scirpo-Phragmitetum, appears to be easily recognizable.

After several pre-Linnean mentions (see: Bureau 1873), the name Morus tinctoria for plants belonging to the present genus Chlorophora was first validly published by Linnaeus (1753). Later combinations were made under Broussonetia Ventenat by Kunth (1817), under Fusticus Rafinesque by Rafinesque (1838), and under Maclura Nuttall by D. Don ex Steudel (1841). Rafinesque (l.c.) based the genus Sukaminea on Morus tinctoria L., without mentioning any species. Gaudichaud (1830) established the genus Chlorophora, based on Morus tinctoria L. Sp. Pl. 1753.

Answering criticism on his proposals for collecting more phenological data in vegetation study, the author argues that 1. Choice of research problems should not be determined by availability of simple methods or measures. 2. Scales for field estimations should be adapted to possibilities for subsequent calculations and use of punch cards. 3. Close cooperation with a mathematician or systems analyst is necessary for a team of ecologists. If this can be achieved, there is a danger of insufficient availability of field data rather than that of stockpiling data that may remain unused. 4. Correct processing of limited data may give misleading results. The most efficient way to check this is the possibility of reference to field notes containing as many...

A revised classification of the mites (Arachnidea, Acarida) with diagnoses, a key, and notes on phylogeny
Provedor de dados: 16
Autores: Hammen, L. van der.
INTRODUCTION In 1961 I published a paper on a species of the genus Holothyrus, in which I paid also some attention to the general classification of the mites. Before that time I had chiefly studied Oribatid mites, and I was surprised by the neglect of important discoveries made in the field of Oribatid morphology by specialists of other groups. I realized that a comparative study of acarid morphology was badly needed, and that this could be the only base for a satisfactory general classification. I continued and developed this idea, and in the course of ten years I investigated, in a more or less detailed way, representatives of all groups of mites. In this way I published papers on Opilioacarida (Van der Hammen, 1966, 1968a, 1968b, 1969b, 1971),...

Imperfect states and the taxonomy of the Pezizales
Provedor de dados: 16
Autores: Paden, J.W.
Certainly only a relatively few species of the Pezizales have been studied in culture. I hope that this paper will stimulate more efforts in this direction. A few patterns are emerging from those species that have been cultured and have produced conidia but more information is needed. Botryoblastospores ( Oedocephalum and Ostracoderma) are frequently found in cultures of Peziza and Iodophanus (Pezizaceae). Aleurospores are known in Peziza but also in other genera. Botrytis-like imperfect states are known in Trichophaea (Otidiaceae). Sympodulosporous imperfect states are known in several families (Sarcoscyphaceae, Sarcosomataceae, Aleuriaceae, Morchellaceae) embracing both suborders. Conoplea is definitely tied in with Urnula and Plectania, Nodulosporium...

The spreading of Fissidens crassipes Wils. (Musci) in the Netherlands
Provedor de dados: 16
Autores: Florschütz, P.A.; Gradstein, S.R.; Rubers, W.V.
In the last few years a rapid spreading of Fissidens crassipes Wils. along the main rivers in the Netherlands has been observed. The distinguishing characteristics, the distribution, ecology, and reproduction of the species are discussed. It is suggested that the spreading results from a raise in water temperature in the rivers due to the discharge of increasing quantities of warm cooling water by the industries.

Notes on South American catfishes, including remarks on Valenciennes And Bleeker types in the Leiden Museum
Provedor de dados: 16
Autores: Boeseman, M.
I A recent perusal of Valenciennes' accounts on the nematognathous fishes (Valenciennes in Cuvier &amp; Valenciennes, 1839, 1840) showed that of the numerous South American species newly described or renamed, eighteen wholly or partly were based on specimens in the collection of the Rijksmuseum van Natuurlijke Historie at Leiden. It was surprising to find that most of these specimens are stated to have been sent to Leiden from Cayenne, and only a few from Surinam, for most of the pre-1839 South American catfishes in the Leiden Museum are of Surinam origin and few, if any, from Cayenne. Moreover, an examination of the collection showed that up to recently none of the specimens belonging to the pertinent species bear any indication as to a typical status. On...

Activity of the body wall musculature of the African Clawed Toad, Xenopus laevis (Daudin), during diving and respiration
Provedor de dados: 16
Autores: Jongh, H.J. de.
INTRODUCTION Mechanisms for regulating the specific weight of the body are well known in fishes. In other aquatic vertebrates the lungs might have a function similar to that of the swimbladder or the lungs in fishes. In anuran tadpoles the lungs may serve as hydrostatic balancers, but this has not been verified experimentally. Active regulation of lung volume, and thus of body volume and specific weight, during diving is unknown in adult anurans, although Parker (1936) expressed the opinion that in male Trichobatrachus robustus the lungs, which possess a posterior diverticulum surrounded by specialized musculature, serve as a hydrostatic apparatus. If there is no active regulation of lung volume during diving, the volume of the lungs will depend on such...

Autores: Schaeffer, J.
Pollen grains of 34 species of the genus Hydnocarpus (Flacourtiaceae) are described. Two pollen types, one of which is subdivided in two subtypes, are distinguished. Within Flacourtiaceae the pollen of Hydnocarpus is more or less isolated, but the related genus Chlorocarpa has rather similar pollen. In sculpture there exists some resemblance to Paropsia (Passifloraceae).

Provedor de dados: 16
Autores: Freijsen, A.H.J.; Heeres, Els.
By common consent two taxa of Festuca rubra s.l. occur in sandy outer dunes along the N.W. European coasts. Festuca juncifolia St. Amans is considered to be a typical grass of Ammophiladunes. Festuca rubra subsp. arenaria (Osb.) Richt. could be found on almost fixed dunes. The only usable character mentioned in morphological descriptions, is formed by the sclerenchyma in the leafblades. In Festuca juncifolia the sclerenchyma must be present in a thick continuous layer. In Festuca rubra subsp. arenaria the sclerenchyma must consist of separate strands. In 1966 and 1967 58 samples of Festuca-plants, both vegetative shoots and culms, were collected on the outmost dune ridge on the island of Voorne (Netherlands). Almost all plants investigated appeared to...

The sole species of Tepualia Griseb., Goett. Abh. 6 (1854) 119, T. stipularis (Hook. f. et Arn.) Griseb., loc. cit. 119, occurs in South America remote from the main Australasian concentration of the subfamily Leptospermoideae. It is the only representative of the subfamily in the Americas. The species was first placed in Myrtus (Hooker and Arnott, 1833), later transferred to Metrosideros (J. D. Hooker, 1847), and was finally segregated as a new genus by Grisebach (1854). Grisebach (1.c., 120) described a second species, T. philippiana, which is now treated as a synonym of T. stipularis. Tepualia stipularis is restricted to southern Chile and southern Argentina in lowland to lower montane sites where, according to herbarium labels, it grows in open, often...

Miscellaneous botanical notes XXII

Autores: Steenis, C.G.G.J. van.
During a botanical tour in North Vietnam in 1961 Dr. Jeanplong collected a small Liliaceous plant which he could not check at the Paris Herbarium. Sending a duplicate to Dr. W. T. Stearn at the British Museum, the latter suggested it to belong to the tribe Johnsonieae to which Jeanplong agreed, classifying it as a new monotypic genus Halongia, next to the New South Wales Alania. My attention was drawn to it through the figures provided in the paper published recently by Jeanplong, which strongly reminded me of Thysanotus chinensis, a widely distributed member of an otherwise Australian genus, occurring from northern Australia with gaps to Thailand and China. Besides, a new Liliaceous genus from Indo-China would be quite unexpected.

Until recently Gagea lutea and Gagea spathacea were known from only a small number of localities in the province of Drente. In the years 1969 to 1971 a large number of new localities of both species was discovered. Gagea lutea is only recorded in or close to villages on the “Hondsrug”, a ridge formed during the Riss glacial period. In the villages of Eext and Gieten this species is found in at least 12 localities, under hedges, in gardens, along roadsides, etc. In the northern part of the province of Drente Gagea spathacea was found in several places, nearly all of them in small relicts of woodland (Alno-Padion and Carpinion).

It has been suspected for some time that Tetrameles nudiflora occurs in the Cape York Peninsula region of Queensland. The late Mr. L. S. Smith (Queensland Herbarium) referred some sterile specimens to this species, but, as far as is known, he never saw fertile material from Queensland. Mr. G. C. Stocker (Forestry and Timber Bureau, Atherton) collected good fruiting material of this species in the McIlwraith Ra. (13°50' S, 143°20' E) in November 1971 (Stocker 820). This appeared to be the first collection of fertile material. However, subsequent discussion with Mr. J. G. Tracey and Dr. L. J.

Dr. D.M.W. Anderson, of the Department of Chemistry, West Mains Road, Edinburgh EH 9 3JJ, Great Britain, started work on plant gums some 12 years ago. Of course he has to rely on samples sent to him as most gums come from tropical forests, hence this request. Though my experience learns me to be pessimistic about results of requests, I will go on with the good work of stimulating collaboration. It cannot be sufficiently emphasized that there is for progress of science a desperate need for this cooperation between laboratories situated in the temperate zone and workers in the tropics and subtropics.

Members of the Echinogammarus simoni-group and the genus Eulimnogammarus (Crustacea – Amphipoda) from the Iberian peninsula and North Africa, with description of a new species
Provedor de dados: 16
Autores: Pinkster, S.; Stock, J.H.
Systematic sampling proved that members of the Echinogammarus Simonigroup are the dominant freshwater amphipods in the southern half of the Iberian peninsula. It became clear, that the presence (as recorded in literature) of E. simoni in the system of the river Duero was due to confusion with members of the genus Eulimnogammarus. The systematical position of the simoni – group within the genus Echinogammarus is discussed and comparative descriptions of all the members of this group are given, along with a key for their identification. Where possible, notes are given on the variability and ecology of the different species.

Then he proceeded to Java to work at Herbarium Bogoriense. Upon his repatriation he started to revise the genus Lycopodium for the Flora Malesiana (and as a thesis) but also became a teacher at The Hague, so that this work proceeded only slowly. He died at The Hague, suddenly and unexpectedly, at the age of 57, 26th March 1972. Barnett, Miss Euphemia Cowan She was formerly assistant of Dr. W.G.

Over de taxonomische plaats en de variabiliteit van de subspecies van Lotus corniculatus L. in Nederland
Provedor de dados: 16
Autores: Vries, Willie de.
As a result of an investigation on the variability in morphology, anatomy and cytology in relation to ecological behaviour of the subspecies of Lotus corniculatus L. in the Netherlands, we found subsp. corniculatus as an ecological-plastic taxon with a number of modifications. In subsp. tenuis we could distinguish two ecotypes, respectively of a saltish and a non-saltish habitat. The non-saltish ecotype grows together with the subsp. corniculatus. Furthermore there is a difference between epidermal pattern and stomata of both subspecies (fig. 3 &amp; 4). Moreover differences in the number of chromosomes were found confirming the literature, namely subsp. corniculatus 2n=24 and subsp. tenuis 2n=12.

It was on the 31st of October 1901 that Cornelis Gijsbert Gerrit Jan van Steenis was born at Utrecht, as a first child to H. J. van Steenis and Louisa W. S. van Vuuren. His parents were at the time respectively 39 and 37 years old; both had been educated as schoolteachers. They were late to start a family, but life had not been easy for Hendrik Jan, who had been a follower of the anarchist Domela Nieuwenhuis and would remain all through his life an idealist, pacifist, and at least later an extremely religious man. When the poet and author Frederik van Eeden started his community ‘Walden’, he and his fiancée became members and married early in 1901. Walden proved another deception and with a child on its way it was decided to accept a job as a...

The written history of Haplolobus is still less than one century old. O. Beccari, the great Italian naturalist, was the first to collect a specimen of this genus, June 1866 in Borneo, the only Haplolobus ever collected in W. Malesia! He, too, was apparently the first to recognize this genus as separate from Santiria, probably in 1872, but he never published it and his annotation became forgotten in his herbarium in FI (see Husson &amp; Lam, Blumea 7, 1953. 456). The first species were described in 1889 by K. Schumann (in K. Sch. &amp; Hollr., Fl. Kais. Wilh. Land) under Santiria. Only in 1931 the genus was split off from Santiria and formally described by H. J. Lam. The first revision appeared in 1932 (H. J. Lam, Bull. Jard. Bot. Btzg III, 12, pp....

Taraxacum limnanthes was described by HAGLUND (1946). VAN SOEST (1965) distinguishes two subspecies. One of these, subsp. limnanthoides, occurs in the Netherlands. In this country it is found on the Wadden Islands, near the IJssel Lake (the former Zuiderzee), and in Zeeland. The present paper is concerned with investigations on Schiermonnikoog (one of the Wadden Islands). Here T. limnanthes subsp. limnanthoides occurs in an area with a west to east salt gradient. The habitat of maximum abundance consists of moist dune valleys characterized by a peaty soil. The soil water, which is practically fresh, has a strongly fluctuating level. The adjacent salt marshes which are periodically inundated by the sea show a lower density of the species. T. limnanthes...

Some remarks on the African wild ass

Autores: Bemmel, A.C.V. van.
INTRODUCTION Without any doubt the African Wild Ass should be considered a species threatened with extinction. Therefore, it seems worth-while to collect as many data on this species as possible and to do this quickly. Data and material, however, are scarce. Many sportsmen and zoologists observed the animal in natural conditions and hardly any book or paper on the wildlife of regions in which Wild Asses occurred or still can be found, fails to record some observations. However, these observations mostly are more or less incidental. Only during the last years some special studies have been made on the last remnants of the Wild Ass in Ethiopia and Somalia (Simon, 1966, 1968; Blower, 1968; Klingel, 1971a, b), in order to prepare some measures for the...

Description and remarks concerning two species from Saint Paul and Amsterdam Islands. The first record of Ovalipes trimaculatus (de Haan, 1833) from Saint Paul Island means a large eastward extension of the previously known distribution of the species (South America, Tristan da Cunha and South Africa). Some pelagic Grapsidae from Amsterdam Island are regarded as conspecific with the specimens of Pachygrapsus sp. recently described from Tristan da Cunha Islands by Holthuis &amp; Sivertsen, and identified as Planes marinus Rathbun, 1914, a species new to the Indian Ocean. Lepas anatifera anatifera is recorded as epizoic on a pereiopod of this latter brachyuran.

Revisionary notes on the Sphenomorphus isolepis complex (Lacertilia, Scincidae)
Provedor de dados: 16
Autores: Storr, G.M.
Taxa that have only just attained specific distinction from each other can be of great interest to students of evolution, though their classification may pose serious problems for taxonomists. For example, the sparrows Passer domesticus and P. hispaniolensis behave as good species in most parts of their shared range but hybridize in other parts. The gulls of the Larus argentatus complex form a ring of annectant races around the Holarctic, but their overlapping terminal segments behave as good species in western Europe. Each of these phenomena (described by Mayr, 1963) is paralleled in Australian skinks of the genus Sphenomorphus, the first in the richardsonii complex and the second in the isolepis complex. Previous analyses of these complexes (Storr, 1967)...

Anatomical contributions to plant taxonomy II. The affinities of Hua Pierre and Afrostyrax Perkins et Gilg
Provedor de dados: 16
Autores: Baas, P.
Vegetative anatomy, fruit and seed structure, and pollen morphology of Hua and Afrostyrax (tropical West and Central Africa) are described in detail. The two genera have many anatomical characters in common (see anatomical family diagnosis on p. 182) but are sufficiently different from other families to justify the existence of the family Huaceae. Some characteristic features are discussed and the results of comparisons with representatives of about 50 families are reported. Afrostyrax is not related to Styracaceae, nor is Hua to Erythroxylaceae as had been suggested in the past. Sterculiaceae and Bombacaceae appear to have the highest number of characters in common with Huaceae of all the families compared. This supports the inclusion of Huaceae in the...

A new species of the genus Linuparus (Crustacea, Palinuridae) from South-East Africa
Provedor de dados: 16
Autores: Berry, P.F.; George, R.W.
INTRODUCTION The genus Linuparus White was recently reviewed by Bruce (1965) who gave an excellent account of two species, the type species L. trigonus (Von Siebold) and a previously undescribed species L. sordidus Bruce from the South China Sea. George &amp; Main (1967) reviewed the family Palinuridae and suspected that "four geographically isolated species are probably represented within the recorded distribution of Linuparus; one in Japan (trigonus), one in South China sea (sordidus), one off Portuguese East Africa. .. and one off east Australia...". During 1970, when one of us (R.W.G.) visited the Oceanographic Research Institute at Durban, the opportunity was taken by us to assemble relevant specimens of Linuparus for comparison and review of that...

An account of money Spiders from down under (Araneida, Linyphiidae)

Autores: Helsdingen, P.J. van.
The Australian and New Zealand regions so far were left out of consideration when studying the Linyphiidae (Linyphiinae) on a world-wide basis. When revising the genus Linyphia it appeared that a fair number of species had been described from these regions; but it also became very clear, by a superficial investigation, that these species were so completely different from our European concept of Linyphia and related genera, that they were best put aside then with a view to paying more attention to that part of the world at a later time. A small collection of Linyphiidae from Australian caves, recently received from Mrs. Barbara York Main, Nedlands, Western Australia, offered an excellent opportunity to become better acquainted with the interesting fauna of...

Provedor de dados: 16
Autores: Kimbrough, J.W.
Many of the genera placed in the Pseudoascobolaceae by Boudier do not show true relationships and were based on the number of asci and ascospores, and other superficial features. Qualitative microscopic and microchemical characters of the asci and ascospores, combined with characters of ascocarp development, cultural features, and cytological aspects will provide a more natural classification of this group. The genera of the Thelebolaceae are discussed.

Eleven species of Gammaridae, belonging to six genera, have been recorded from Corsica. Of these, only three are purely limnic, all others are found in mixohaline habitats. The three limnic species show a clear systematic relationship to italian taxa; the mixohaline species are of a circum-mediterranean type. Apart from two apparently endemic species of the genus Niphargus, there is no pronounced endemism in the corsican Gammaridae.

A new genus for the Australian leptodactylid frog Crinia darlingtoni
Provedor de dados: 16
Autores: Tyler, M.J.
INTRODUCTION Crinia darlingtoni Loveridge, 1933, was described from a series of four specimens collected by P. J. Darlington at the Queensland National Park, Macpherson Range, Queensland, and distinguished by the rudimentary condition of the first finger and the extremely small first toe. Loveridge noted that some specimens bore a resemblance to C. acutirostris Andersson in colouration but did not discuss the phylogenetic relationships of his new species. For a generic revision Parker (1940) examined a juvenile paratype and on the basis of a similarity in the condition of the prevomer, he associated C. darlingtoni with C. leai Fletcher, C. rosea Harrison and C. laevis (Günther). In the last species he also recognized two sub-species, C. l. laevis and C. l....

Macrofauna van de wateren in "De Grrote Peel" : een voorjaarsbeeld
Provedor de dados: 16
Autores: Nieukerken, E.J. van; Tol, J. van.
The waters of the State Reserve "De Groote Peel", situated on the border of the provinces of North-Brabant and Limburg in the Netherlands, were investigated during Easter 1971 (8-11th of April). The reserve is a former peat-moor, where peat was cut until the first half of this century. Now vast areas of Molinia caerulea with wild shoots of Salix aurita and Betula pubescens are found. Special attention was paid to waterbugs (Heteroptera aquatica and semi-aquatica) and waterbeetles (Coleoptera aquatica). The species present indicate slightly polluted oligotrophic water. The pollution is probably caused by three factors: the inflow of eutrophic water, the breeding of Blackheaded Gulls (Larus ridibundus) and the tourists. Table 1 gives a list of the...

Aspects of the ecology of mosquitoes in Surinam
Provedor de dados: 16
Autores: Kruijf, H.A.M. de.
For about two years (1967—1968) investigations were conducted on the ecology of mosquitoes in relation to the transmission of arboviruses in Surinam (DE KRUIJF 1970). Part of this study dealing with the daily activity of biting mosquitoes is presented here. Daily activity of biting anopheline females has been widely studied because of their ability to transmit malaria (MATTINGLY 1949, SENIOR-WHITE 1953, GILLIES 1957, SLOOFF 1964, and many others). Intensive studies on culicine mosquitoes transmitting arboviruses and other pathogen agents have been carried out in Africa and elsewhere (among many others HADDOW 1945, 1954, 1956, 1961a and b, 1961, MCCLELLAND 1960, BOORMAN 1961, SAMARAWICKRAMA 1967, TAYLOR &amp; JONES 1969).

A prograding deltaic complex in the Upper Carboniferous of the Cantabrian Mountains (Spain): the Prioro-Tejerina basin
Provedor de dados: 16
Autores: Loon, A.J. van.
In the southern flank of the Cantabrian Mountains, northwestern Spain, a sequence of Upper Carboniferous sediments is exposed in a synclinal structure, probably coinciding with the original basin, near the villages of Prioro and Tejerina. By means of palaeontological dating with several fossil groups (e.g. fusulinids, brachiopods, calcareous algae and land plants) the lower sequence of these sediments could be dated as Westphalian B/C to lower or middle Westphalian D (Yuso Group). After a relatively short time interval follows a sequence with an uppermost Westphalian D to lower Cantabrian age (Cea Group). These two groups are separated by an angular unconformity. These sediments together represent a regressive sequence, starting with a turbidite facies and...

The identity of zostera marina var. angustifolia Hornemann (Potamogetonaceae)
Provedor de dados: 16
Autores: Hartog, C. den.
Since Hornemann (Fl. Dan. 9, 1816, p. 3, pl. 1501) published the name Zostera marina var. angustifolia together with a very poor drawing and the extremely short diagnosis ‘foliis subenerviis’ several interpretations of the identity of this taxon have been given. Some authors regarded it as a separate species closely related to Z. marina L., e.g. Reichenbach (1c. Fl. Germ. 7,1845, p. 3, as Z. angustifolia), and Tutin (J. Bot. 74, 1936, p. 227—230, as Z. hornemanniana). Others thought that it was a hybrid between Z. marina and Z. noltii Hornem., e.g. Ascherson (in Boissier, Fl. Orient. 5, 1882, p. 25), Prahl (Krit. Fl. Schlesw.- Holst. 2, 1890, p. 211), and Rouy (Fl. Fr. 13, 1912, p. 290, as Z. hornemanni). Recently I myself expressed the opinion that...

A sexual mosaic with internal embryogenesis in the dioecious Horseshoe Crab, Limulus polyphemus
Provedor de dados: 16
Autores: Bennett, D.C.; Pezalla, P.D.; Herman, W.S.
The chelicerate arthropod Limulus polyphemus is a dioecious species, with external fertilization and development, in which the sexes can usually be readily distinguished (Shuster, 1960). In males the genital papillae are pointed, while in females they are blunt. In addition, the first walking leg of the mature male bears a claw-like appendage used for clasping the female during fertilization. Internally the gonads of both sexes are highly branched structures distributed throughout the cephalothorax. In February of 1972 we obtained an animal from the Woods Hole Marine Biological Laboratory, Woods Hole, Massachusetts, that appeared to be a mature male. The animal was about 17 cm wide across the carapace and possessed male claspers on both sides of the body....

Provedor de dados: 16
Autores: Purves, P.E.; Bree, P.J.H. van.
Cadenat (1959) and Rancurel (1964) produced strong indirect evidence that off the west coast of Africa, the Bottle-nosed Dolphin, Tursiops truncatus, is in the habit of diving very deeply, possibly down to 600 m. Examination of the skulls of fully adult specimens of Tursiops taken off Dakar and St. Helena revealed marked distension and fenestration of bones associated with the accessory air sinuses of the middle ear. The condition suggests a pathological enhancement of the normal processes of evolution of these bones in order to adjust to excessive middle ear pressure sustained intermittently over a long period.

Observations on the vertebral hypapophyses and associated Musculature in some snakes, with special reference to the Colubridae
Provedor de dados: 16
Autores: Malnate, E.V.
Hypapophyses are reported to be present on the anterior precaudal vertebrae of representatives of all snake families, except the Typhlopidae, Leptotyphlopidae, and Uropeltidae. The processes occur on all precaudal vertebrae in the Acrochordidae, Colubridae (auct.), Elapidae, Viperidae, and two subfamilies of the Boidae, the Bolyerinae and Tropidophinae. Among the numerous genera of the Colubridae caudal extent of the presence of the hypapophyses is variable, even within a genus or species. Cope (1864) associated hypapophyses on the posterior precaudal vertebrae with the Homalopsinae. In the years following he utilized the character to distinguish the Homalopsinae (1886), the Colubrinae (1887), the Natricidae (1893); in his last classification (1900), Cope...

The Stenogastrinae, a group of subsocial wasps currently regarded as a subfamily of the Vespidae (Richards, 1962: 4), have a remarkable distribution. Most of the species are inhabitants of the Oriental region, where their range extends from Southern India eastward to the Philippine Islands, Celebes, Sumba and Flores. No Stenogastrinae have ever been collected in the Moluccas, but the group is well represented in the Papuan area, occurring throughout New Guinea and in the neighbouring islands of Waigeo, Misool and Aru. From 1831 to 1913 nine species have been described from this area, but from examination of the types we have learned that only six of these may be regarded as good species.

Provedor de dados: 16
Autores: Vaupel-Klein, J.C. von.
INTRODUCTION The present paper deals with some morphological features found in the species of the genus Euchirella Giesbrecht, 1888, family Aetideidae. In the course of my studies on the genus, I noted that the structures situated on the anterior surface of the endopodites of the first pair of swimming legs, which will be described below, have never been given the attention they obviously deserve. In none of the principal works on Calanoida, e.g., Scott (1909), Sars (1924-25), Rose (1933), and Brodskii (1950) these structures are dealt with in the text. The same holds for the important reviews by Vervoort (1957, 1963), and Tanaka &amp; Omori (1969). Although most authors somehow figure a row of spinules on the tubercle of the endopodite, their drawings are...

Note on the early development of the integument in some Juglandaceae together with some general questions on the structure of Angiosperm ovules
Provedor de dados: 16
Autores: Heel, W.A. van; Bouman, F.
Recently a review on the Angiosperm ovule has been published by the well-known Indian botanist V. Puri (1970). In this review the author stressed the differences between Angiospermous and Gymnospermous ovules, and he refused to accept their comparability or common descent. In this respect Puri comes close to Eames (1961). Both authors tend to regard the ovules as complex emergences. Apart from the main theme, there is a striking passage in this review dealing with the Hugo de Vries Laboratory at Amsterdam. According to Puri in that laboratory facts are sacrificed for hypotheses (p. 10). In the following we would like to start with the facts concerned and present them in a more convincing way, and then ask some simple questions on the structure of the...

Developmental Stages of some Tropical and Subtropical Planktonic Marine Copepods
Provedor de dados: 16
Autores: Björnberg, Tagea K.S.
Most planktonic marine copepods have nauplii which differ greatly from the copepodids so that it is difficult to relate them to the adult form. Rearing experiments are usually unsuccessful; only 8% of ca. 800 species of planktonic marine copepods have identified nauplii (see below cited list). To this 8% the following species are added in this work: Acartia lilljeborgi, Calocalanus styliremis, C. pavo, Candacia sp., Clausocalanus furcatus, Centropages furcatus, Corycaeus amazonicus, C. giesbrechti, C. speciosus, Farranula gracilis, Labidocera fluviatilis, Microsetella rosea, Oithona oculata, O. ovalis, O. plumifera, O. simplex, Oncaea media, O. venusta, Paracalanus crassirostris, Pontellopsis sp., Pseudodiaptomus acutus.

Wood structure of the genus Talisia (Sapindaceae)
Provedor de dados: 16
Autores: Mennega, Alberta M.W.
A description of the wood structure of 15 species of Talisia from the Guianas and adjacent areas is given. Among the neogean genera of the Sapindaceae Talisia is readily recognized by the combination of moderately few vessels, uniseriate or bi-seriate homocellular rays, aliformconfluent to banded parenchyma, the cells often containing rhombic crystals, and thick-walled fibres with a narrow lumen. The wood structure of the species is much alike, and it is not possible to identify a wood specimen to species on wood structure alone. It is pointed out that nearly identical wood occurs in the genera Guarea and Trichilia of the Meliaceae; the resemblance to some genera of tropical South American Leguminosae is more superficial.

Natural and semi-natural vegetation in Japan
Provedor de dados: 16
Autores: Numata, M.; Miyawaki, A.; Itow, D.
Studies on the composition of the forests and other vegetation of Japan were initiated by J. Tanaka (1887) in the Meiji Era. According to his introduction his field survey started in 1879 and resulted into a classification of vegetation zones (forest zones), mainly of the lowland, based on physiognomy and dominant species. In later years some other major proposals of the vegetation zonation were made. Honda (1900) distinguished also altitudinal zones, based on his survey on dominance, and provided it with the first vegetation map. Nakano (1942—1943) stressed the physiognomy combined with species composition, sociology, and succession but did not produce a map. Kira (1949) described the forest zones of Japan stressing the climax concept and correlating...

Floristic and Cytotaxonomic notes on the flora of the Maltese Islands
Provedor de dados: 16
Autores: Kramer, K.U.; Westra, L.Y.Th.; Kliphuis, E.; Gadella, Th.W.J.
In the spring of 1968 and 1969 the two senior authors visited the Maltese Islands of Malta and Gozo and collected and photographed plants. The entire herbarium collection amounts to about 350 numbers. The first set is deposited in the herbarium of the State University of Utrecht; duplicates were sent chiefly to the herbarium of the Royal Botanic Gardens, Edinburgh. Critical determination of the material yielded some results which may be interesting from a floristictaxonomic viewpoint and are therefore reported below. Beside herbarium material fruits and seeds were collected; the samples that germinated were investigated cytotaxonomically by the two junior authors. The results are also presented in the following. The first truly comprehensive account of the...

On a Luxation of the skull-atlas joint and consecutive ankylosis in a Grey Seal, Halichoerus grypus (Fabricius, 1791), with notes on other Grey Seals from the Netherlands
Provedor de dados: 16
Autores: Bree, P.J.H. van.
On January 3, 1969, about 1 km south of Zandvoort, Netherlands, a very young female Grey Seal was found on the beach. The animal was exhausted and in a bad condition and could therefore be caught. It was taken to the Amsterdam Zoo where, in spite of good care, it died on February 17 of the same year. While living in the Zoo it was noted that the seal from time to time had convulsions, that it was partially lame, and that its head was positioned in a rather unusual manner. After its death, the Grey Seal was brought to the Zoological Museum of the Amsterdam University for dissection. During the dissection and more clearly afterwards when the whole skeleton was cleaned, a luxation of the skull-atlas joint and a consecutive ankylosis was observed (see plate...

Taccaceae
Provedor de dados: 16
Autores: Drenth, E.
The affinity of Taccaceae has been subject to diverse opinions, many authors favouring a place near Dioscoreaceae, but in my view the unisexual flowers, the branching habit, the racemose inflorescences and the 3-celled ovary in that family make this not very probable. I prefer to share the opinion of those who seek its affinity to Amaryllidaceae, because of the habit, the scape-shaped inflorescence, the umbellate flower disposition with an involucre, and the fact that in that family also occasionally a 1-celled ovary is found. Neither the systematic anatomy nor the inadequately known phytochemistry or chromosome number are sufficiently diagnostic to support opinions on affinity. Before my precursory revision (1972) two genera were distinguished, viz Tacca...

The bibliography of a hitherto inaccurately described anonymous eighteenth-century popular German work on natural history is given, dealing with mammals, birds, fishes, amphibians and reptiles. As an addendum to this work the publisher has given an engraving of an unknown fish from the river Lech, river system of the Upper Danube. The fish could be identified as the cyprinid Leuciscus meidingeri Heckel, 1852. The observation of the species was made 66 years before its recognition as a new species by Heckel.

The species of Stegonotus (Serpentes, Colubridae) in Papua New Guinea
Provedor de dados: 16
Autores: Mcdowell, S.B.
INTRODUCTION Currently, New Guinea Stegonotus with 17 scales at midbody and divided subcaudals are identified as S. modestus. But this will not account for the disparity in dentition within "S. modestus", nor the colour differences even at one locality, nor that in East and West Sepik Districts there are three quite distinct "S. modestus": (1) a large form with high ventral count and high tooth count; (2) a small form with low ventral count but high tooth count; and (3) a medium-sized form with high ventral count but low tooth count (fig. 1). The material in the British Museum and American Museum of Natural History indicates that scale count does not correctly identify the species, and that such features as dentition, form of the palatine bone, scale pits,...

A new scincid lizard of the genus Tribolonotus from Manus Island, New Guinea
Provedor de dados: 16
Autores: Cogger, H.G.
INTRODUCTION The scincid lizards of the genus Tribolonotus are generally dull-coloured, armoured, thigmothermic, cryptozoic lizards with several unique features in their morphology and biology. These features include the possession of abdominal glands and volar pores, a vestigial left oviduct, the production of a single egg or young (in all species so far investigated) and an ability to vocalize (in at least one species) otherwise unknown within the family Scincidae. As a result of two recent papers (Zweifel, 1966; Greer &amp; Parker, 1968) the taxonomy of the genus is firmly based, while many aspects of the biology and ecology of various species have been documented. In the course of field work in New Guinea in 1969, as part of Program Β of the 1969...

The catazonal poly-metamorphic rocks of Cabo Ortegal (NW Spain), a structural and petrofabric study
Provedor de dados: 16
Autores: Engels, J.P.
The petrological study of the southern part of the Cabo Ortegal area is a complement of Vogel’s (1967) investigation of the northern half. The present investigations include a structural as well as a petrofabric study. The rocks belong to an eugeosynclinal sequence which during the Precambrian underwent prograde metamorphism from the staurolite-almandine-muscovite and the kyanite-almandine-muscovite subfacies of the almandine-amphibolite facies through the clinopyroxene-pyralmandine (± hornblende) granulite facies into the eclogite facies (M1). Several of these zones, bounded by isogrades, which are sometimes tectonic in nature, have been mapped. From the fact that the banded gneisses are only metatexitic and from the jadeite content of omphacite, the P/T...

Review
Provedor de dados: 16
Autores: Heel, W.A. van.
This book is an exploration into the field of Plant Morphology. It deals with the placentation of the ovules in ten families of Centrospermae — including the Cactaceae — and in the Primulaceae. The core is formed by a very close observation and a complete documentation of the histogenesis of the ovary wall, the septs, and the placentae in four Caryophyllaceous species. Furthermore, the result is compared with similar known and newly discovered features in other species and in the other families. It appears that the ovary is composed of a cup of sterile phyllomes which surrounds a central body. This central part is built up by two alternating sets of five axial placentae bearing the ovules. The septs grow from the cup inwards and fuse with the placentae and...

Juveniles of Cavolinia inflexa (Lesueur, 1813) and Cavolinia longirostris (de Blainville, 1821), their discrimination and development (Gastropoda, Pteropoda)
Provedor de dados: 16
Autores: Troost, D.G.; Spoel, S. van der.
In C. inflexa the mantle gland and its border show twenty-two bands. Differences in banding with C. longirostris are discussed. It appeared to be possible to discriminate the soft parts of juveniles in both species. Of special value for discrimination is the shape of the lateral appendages. The shells can be distinguished by the relative length of the caudal spine, which is longer in C. inflexa than in C. longirostris. Different developmental stages of C. longirostris are described and those of C. inflexa are added for comparison. While for the latter species the soft parts grow larger parallel with the increment of the shell, this is not the case in C. longirostris, due to the occurrence of minute stages and shedding of the caudal spine. The differences...

A technique for collecting botanical specimens in rain forest
Provedor de dados: 16
Autores: Hyland, B.P.M.
I. Introduction — The need for a simple method of collecting botanical material from rain-forest trees became evident during the construction of a field key to the rain-forest trees of North Queensland. Many collecting techniques have been developed, e.g. throwing sticks and stones, severing branches with rifles and shotguns, felling trees with axes and saws, breaking branches with hand thrown lines and using monkeys to climb and pick twig samples. However, the collection of botanical material from rain-forest trees is a difficult and time-consuming task. The problem is not as great in forests consisting of a small number of tree species. In such forests it is generally possible to visually group the trees into species assemblages without knowing the...

On the occurrence of Carcinus maenas (Linnaeus) and its parasite Sacculina carcini Thompson in Burma, with notes on the transport of crabs to new localities
Provedor de dados: 16
Autores: Boschma, H.
From time to time crabs have been found in localities at great distances from their normal area of distribution, owing to their being transported by ships in ballast water tanks or on the hulls. Much attention has been paid to a report by Catta (1876), who examined the Crustacea taken from the hull of a ship that had made the voyage from India to Marseilles.  Among these, four species of crabs of the family Grapsidae were represented, one of which, named by him Plagusia squamosa, being present in hundreds of specimens. Catta saw here the possibility of an extension of the area of distribution of the crab, but apparently the conditions of life were not favourable in the new locality, and the crab did not become established here. Stebbing (1893: 99) remarks...

INTRODUCTION During the week 7th to 12th June, 1971 opportunity was taken of accompanying members of the I.B.P. team based at the Tjeukemeer, the Netherlands, on a boat journey through the Friesland lakes. The main aim of the author was to collect Turbellaria (Tricladida and Microturbellaria) from the vegetation and stones in the littoral zone of 16 lakes (see Table 1). However, any specimens of Gasteropoda and Hirudinea obtained in samples were also noted.  METHODS In the reed beds, mostly Phragmites (see Table 1), an F.B.A. net (60 meshes/inch = approx. 23.6 meshes/cm) mounted in a square frame on a 5 ft.

Man könnte deshalb erwarten, dass sie auch zoogeographisch wichtig sei, und in ihrer Fauna Elemente östlicher und westlicher Herkunft vereinigen dürfte. In diesem Zusammenhang ist es merkwürdig, ja nahezu unverständlich, dass die Insel von zoologischen Sammlern fast vollständig vernachlässigt worden ist und dass z.B. nie eine Liste ihrer Avifauna veröffentlicht wurde. Seit Sonnerat (1776) im Jahre 1770 die Insel besucht und dort wohl einige Vogelarten gesammelt hat (sicher Eos...

I must apologize that this Bulletin appears late. Material had been assembled for it and I had anticipated to compose this number about Christmas 1971. But on my birthday, 31 Oct. 1971, it was announced as a complete surprise that the firm of Brill was authorised to publish a book on the Javanese Mountain Flora of which the core is 57 hand-coloured plates on which 456 different species are depicted. The fieldwork was done, and drawings were composed in 1939-1941. After the war no publisher could be found; a precursor with 4 plates appeared in Endeavour (21, 1962, 183-193). The condition attached to this allowance was that I should promise stante pede to deliver the text by end December 1971 or at least as soon as possible, because the promotors of the plan...

Autores: Kits van Waveren, E.
The species of the genus Psathyrella listed by Romagnesi (1953: 355) in the groups of Atomatae and Pronae are brought into one section, section Atomatae. This section is divided into a coprophilous and a non-coprophilous group. Fifty-four collections of species, belonging to this section were examined, including type material of Drosophila picta Romagn., D. orbitarum Romagn., and D. albidula Romagn.; herbarium material of Psathyrella atomata (Fr.) Quél, and Drosophila infida Quél., received from Prof. H. Romagnesi; type material of Psathyrella coprophila Watling, P. fimetaria Watling, and P. vinosofulva Orton. A new species, P.

El Titiribí (Pyrocephalus rubinus) es un ave abundante y conspicua en América. Pese a ello es poco conocida en sus aspectos de comportamiento. Se ha estudiado detenidamente, especialmente desde el punto de vista de su comportamiento reproductivo, encontrando que, la especie se reproduce durante todo el año, empleando frecuentemente cada pareja el mismo nido para hacer varias posturas. Se sacan algunas conclusiones sobre mortalidad en los distintos estados de desarrollo, desde la postura hasta la salida de los pollos del nido. Se describe igualmente el comportamiento de los padres, respecto a la fabricación del nido y al cuidado de los pollos. Se hace una análisis de los distintos tipos de canto y vuelo, y su significado.

El Rodadero (Santa Marta), centro turístico o colonia de vacaciones?
Provedor de dados: 20
Autores: Mertins, G.
A partir de 1960 y con mayor intensidad a partir de 1965 se convirtió el Rodadero en el balneario preferido por los colombianos durante ciertas épocas del año en el Mar Caribe. Anteriormente solo era una playa desolada, donde se encontraban dispersas algunas chozas de pescadores. El Rodadero ha sido clasificado por la prensa colombiana y por la opinión pública como el "centro turístico de Colombia" o "la perla del Caribe". Más aún, se lo ha colocado entre la categoría de los balnearios lujosos internacionales, que existen en la región del Caribe (como Acapulco, Miami etc.). En 1969/70 se realizó una investigación socio-económico en el Rodadero, debido a que se presentan fuertes argumentos en contra de lo arriba mencionado. De acuerdo con las...

Relation entre des populations successives de phytoplancton et de bactéries hétérotrophes dans le Bassin de Chasse d'Ostende (Belgique), en 1971
Provedor de dados: 27
Autores: Podamo, J.
When the sluices of the "Bassin de Chasse" in Ostend were closed, on the 31th March 1971, we observed an important decrease of the number of heterotrophic marine bacteria in the water: from 5.10&lt;sup&gt;5&lt;/sup&gt; b/ml on 31th March to 10&lt;sup&gt;3&lt;/sup&gt; b/ml on 15th May. This can be interpreted as reflecting the consumption of organic material supporting the growth of the bacteria by the bacteria themselves. The new bacterial populations appearing then were closely related to the phytoplanktonic populations appearing just before them. This relation probably reflects the dependance of the bacteria to the new organic material of the dead phytoplankton cells.

Autores: Podamo, J.
A bacteriological study of the water of the "Bassin de Chasse" of Ostend (Belgium) has been done from 31 March till 29 July 1971, when the dock has been kept closed. The results show a succession of different populations of heterotrophic marine bacteria. This conclusion appears from different results: &lt;ol&gt;&lt;li&gt;total count of bacteria; &lt;/li&gt;&lt;li&gt;separate count of bacteria forming white and coloured colonies; &lt;/li&gt;&lt;li&gt;rough determination (morphology and Gram-reaction) of some bacteria. &lt;/li&gt;&lt;/ol&gt;These population-variations could be explained by variations in the organic matter of the water.

Three simple culture devices for aquatic invertebrates and fish larvae with continuous recirculation of the medium
Provedor de dados: 27
Autores: Sorgeloos, P.; Persoone, G.
The 3 culturing devices described are based on the principle of the classic air-water lift, which facilitates continuous recirculation and aeration of the cultivation medium. The first device is a "circulation cylinder", convenient for hatching eggs of the brine shrimp &lt;i&gt;Artemia salina&lt;/i&gt; and for culturing algae and protozoans. In the second device, an internal basket (i.e., a glass cylinder with plankton-gauze bottom) prevents the animals being carried along in the air-water lift. The third device, analogous to the second, is provided with a lateral waste-drain and a water collector with siphon, which empties regularly into the main culture vessel. The second and third devices proved to be excellent for the cultivation of a variety of...

During ecological investigations on the optimum culturing conditions of ciliates, we studied the influence of a number of abiotic factors on the reproductive potential of the hypotrichous ciliate &lt;i&gt;Euplotes vannus&lt;/i&gt; Muller, such as the nature and the quantity of food, the temperature and the salinity. The experiments were run in petri dishes of 5 cm diameter containing 5 ml of food suspension, and were always started with conjugants. The microphagous &lt;i&gt;Euplotes vannus&lt;/i&gt; thrives on a variety of food media. Excellent results were observed on homogenized bakers yeast, i.e. 10.000-20.000 animals in 5 ml of food suspension. In good culturing conditions the stationary phase was reached in 7 days, which implicates a mean rate of...

La valeur de la méthode otolithométrique pour la détermination de l'age du Merlu (&lt;i&gt;Merlucius merlucius&lt;/i&gt; - Pisces, Gadidae) en Méditerranée
Provedor de dados: 27
Autores: Dupont, E.
The otolithometric method rests on 2 (1) the agreement between the number of annual rings and the age of the fish and (2) the length of the fish being proportional to that of the otolith. The length of the fish may be grouped into 5 classes, ranging from 16, 18, 20, 25 to 27 cm though some degree of overlapping is observed. Using 300 otoliths and grouping the individuals according to the number of annual rings their otoliths bear it was possible to determine the frequency of individuals of varying lengths within a particular class. Although the results obtained by the author helped him to verify the 2nd parameter, numerous shortcomings were seen in this method. No consistent unity of measurement, which could be used for comparison, has been adopted by...

An improved separator box for &lt;i&gt;Artemia&lt;/i&gt; nauplii and other phototactic invertebrates
Provedor de dados: 27
Autores: Persoone, G.; Sorgeloos, P.
1. A simple cylindrical hatching and separator box is described for &lt;i&gt;Artemia salina&lt;/i&gt;nauplii (and other phototactic invertebrates), in which the "corner seeking effect" responsible for poor separation is avoided, and from which nauplii can be recovered very conveniently. 2. Separation is achieved by partly unscrewing an internal and closed cylinder from its fixed counter-part glued to the bottom of the box, till two slits are freed through which the nauplii migrate from the darkened internal hatching cylinder into the illuminated exterior compartment. Rescrewing the former cylinder separates the larvae from debris and unhatched eggs.

A note on salinity and temperature in some Moroccan brackish waters
Provedor de dados: 27
Autores: Heip, C.H.R.; De Coninck, L.A.P.; Engels, P.; Engler, G.; Verschueren, G.
A series of measures of temperature and salinity was made in different brackish waters along the Atlantic coast of Morocco. All waters examined were polyhaline, except for a series of hyperhaline salt mines. The importance of temperature in the sediment is discussed: temperature in the top layer may rise considerably (7° C) above air temperature. However, in the deeper layers, temperature is lower than in the air and the water.

A study of the orange-red pigment from the accessory nidamental glands of the cephalopod &lt;i&gt;Sepia officinalis&lt;/i&gt; L.
Provedor de dados: 27
Autores: Decleir, W.; Richard, A.
In adult female cuttlefish an orange-red pigment concentrates in the accessory nidamental glands. This pigment is tightly bound to granules which are actively secreted by the glands. The only way to dissolve the pigment is an incubation in 40 % NaOH. Afterwards the pigment becomes readily soluble in most organic solvents. Its solubility, its behaviour in thin layer chromatography and its visible adsorption spectrum prove that the pigment is a carotenoid. It is probably formed by oxidation of a carotene. Since its properties do not correspond entirely with those of the known carotenoids, the new cephalopod pigment was called Sepiaxanthine.

Our study about the biotope of the oyster culture, the 'Bassin de Chasse d' Ostende', has shown us that: (1) the phyto- and zooplanktonic population extraordinary abundant let suppose us that the available food is enormous. (2) The harmful organisms (&lt;i&gt;Polydora ciliata&lt;/i&gt;) and the competitors of food for the oyster (&lt;i&gt;Mytilus edulis, Balanus, Mya arenaria&lt;/i&gt;) have fixed them by a clumsy manner on the &lt;i&gt;Ostrea&lt;/i&gt;. (3) The abundance of the competitors did not restrain the growth of the mussels and the oysters. On the contrary, their growth appears to be one of the greatest of Europe.

Résultats d'une étude systématique et écologique de la population algale des côtes rocheuses du Dramont, St. Raphaël (Var, France)
Provedor de dados: 27
Autores: Coppejans, E.
Thanks to this psychological study, stretched over a period of four years (1968-1972) on the algae population of the Le Dramont rocky coasts, we had the possibility to distinguish 19 different groups. Their apportionment and floristic composition have been consciously observed and studied, in summer as well as during spring, and this up to a depth of 45 m. A high number (35) of sections were done for that purpose, all over the work territory. Some of them are reproduced here (fig. 1, 2, 3, 4), with an indication of the placement of the different groups. Next, we compared our results with those of previous works, and we were able to conclude that the studied area is very analogue to the one of the J. Feldman study of the Albères Coast.

A DYNAMIC INVESTMENT MODEL FOR TREE CROP AGRICULTURE
Provedor de dados: 31
Autores: Ajobo,   Owolabi.
The objective of this paper is to develop a dynamic model that may be useful in the analysis of investment in long term tree crop agriculture.  The model is based on linear programming as modified by fixed assets theory.  The starting point is the Heady-Loftsgard dynamic linear programming model restated in a stochastic form and imbedded in a decision theoretic construct to give a stochastic mixed integer programming model.  The paper goes into a discussion of problems associated with agricultural data collection in Nigeria-on the conviction that specific use of any model can only come after the data problem has been reasonably solved.

The Bulk Constraint and Computer Formulations of Least-Cost Feed Mixes
Provedor de dados: 31
Autores: Mohr,   Graeme M.
Conventional linear programming practice in least-cost feed formulation is to introduce a "bulk constraint" row of 100 units and a diet specified in percentage terms. This procedure places an arbitrary density or concentration level on the available nutrients and metabolizable energy within the resultant feedmixes, which is not necessarily consistent with the birds' consumption capacity. In fact, animals and birds have quite flexible consumption patterns and capacities. Growing pullets fed "low-energy" feedmixes can, in pursuit of their energy requirements, consume up to 150 per cent of their "normal" feed intake. Diet specification for growing birds should be in terms of so many ounces of nutrients per day or week rather than in conventional terms of the...

Institutions such as the U.S. Department of Agriculture, universities and private firms have published regularly current and outlook information to the participants of the livestock market.  Information about short-run future tendencies in the market place is a necessary tool used in the decision making process, by hog producers, wholesalers, retailers and others operating in the hog and pork markets. The forecasting techniques which have been used range from very sophisticated ones to simple "rules of thumb" or purely guesses.  Many forecasters use their own procedures and techniques developed after long experience in operating in the market, and they only get their results after much "pencil and paper" work, and frequently the techniques used are known...

Irrigation Decision Rules for Cottongrowing in the Brookstead Area of the Darling Downs
Provedor de dados: 31
Autores: Nuthall,   Peter L.
A decision problem faced by cottongrowers using irrigation is that of deciding the soil moisture level at which irrigation should occur. A simulation model was developed so that the effect on cotton yield of irrigation at different soil moisture levels could be explored. The output from the model was used to develop relationships enabling the determination of an optimal decision rule. The results indicate that under most situations heavy irrigation in the period "first open flowers to first open bolls" will be profitable.

TECHNOLOGICAL DUALISM AND UNEMPLOYMENT IN COLOMBIA
Provedor de dados: 31
Autores: Silva,   Alvaro.
The problem of unemployment in Colombia is very important for a variety of reasons.  A large portion of it can be identified as technological unemployment.  This kind of unemployment is related to the technological dualism, which exists in the economy.  Technological unemployment arises from technological and resource restraints in both sectors, and due to the current composition of effective demand.  The traditional sector uses a technology which is relatively labor-intensive, and depends heavily on simple tools produced domestically.  In contrast, the modern sector uses imported production processes which are relatively capital-intensive and with a limited degree of flexibility in the substitution of labor for capital.  But, labor is abundant, and...

A SUPPLY FUNCTION FOR DAIRY PRODUCTS
Provedor de dados: 31
Autores: Mules,   T.J.
Results of an investigation into factors affecting the aggregate supply of dairy products in Australia are presented. Empirical estimates of the parameters of the supply function, using ordinary least squares, indicate that some concept of average prices for dairy products is a more important determinant of supply than ratios of prices of dairy products relative to prices of production substitutes such as beef cattle or sheep and lambs. The empirical results also indicate that the quota-type effects of the various metropolitan fluid milk schemes are important in determining supply. Effects of new technology on supply could not be quantified due to intercorrelation of explanatory variables.

SUPPLY ANALYSIS FOR CORN IN THE UNITED STATES: THE IMPACT OF CHANGING GOVERNMENT PROGRAMS
Provedor de dados: 31
Autores: Houck,   James P.; Ryan,   Mary E.
This paper has two objectives: to analyze acreage supply relationships for corn, the major U.S. feed grain, during the 1948-70 period and to develop and test a general theoretical model for evaluating farm commodity program effectiveness. Hence, special emphasis is devoted to empirical measurement and analysis of the effects of government feed grain policy and programs as they have evolved since 1948. Particular attention is focused on the voluntary feed grain programs of the 1960's.

An Appreciation of Decision Analysis in Management
Provedor de dados: 31
Autores: Anderson,   Jock R.; Hardaker,   J. Brian.
Decision analysis, the practice of Bernoullian decision theory and Bayesian statistics, is reviewed in relation to its application in management. Aspects of the scaling of beliefs (probabilities) and preferences (utilities) are discussed, focussing on practical problems. It is concluded that the solution of these difficulties may best be sought through more widespread analysis of real-world decisions.

AN APPRAISAL OF THE CURRENT STATUS AND FUTURE PROSPECTS OF UNIONIZATION AND COLLECTIVE BARGAINING IN AMERICAN AGRICULTURE
Provedor de dados: 31
Autores: Hinkston,   Aaron.
Today, the unionizing efforts of farm laborers have reached the highest plateau of achievement since the beginning of those efforts in the United States.  The main reason for this is improved laws, public awareness, and union recognition.  A very strong movement is under way, which is being led by Cesar Chavez.   Now, as always, there is a three-way squeeze between those parties immediately involved.  At one time or another, each of these parties is caught in the middle when the squeeze is vigorously applied.  The farm worker is trying to apply pressure on the farmer; the farmer, in turn, is faced with the fact that he is a price taker rather than a price maker; the consumer is constantly fighting against higher prices, so he, in turn, directs his leverage...

CHANCE AND CHOICE WEST OF THE DARLING
Provedor de dados: 31
Autores: Francisco,   Emilio M.; Anderson,   Jock R.
Twenty-one pastoralists in the West Darling region of New South Wales were interviewed to gain an understanding of the attitudes of managers in this high-risk pastoral area to uncertain prospects. It was found that pastoralists had no difficulty in specifying subjective probabilities but in modifying probabilistic information they were conservative relative to the 'correct' revision implied by Bayes' Theorem. All the surveyed pastoralists were non-indifferent to risk, as evidenced by their non-linear utility functions for gains and losses.

EVALUATING RETURNS TO RESEARCH IN PASTURE IMPROVEMENT
Provedor de dados: 31
Autores: Duncan,   Ronald C.
The objectives of the study reported here were (a) to attempt to identify pasture research findings which have been important for the development of improved pastures in a number of agricultural regions, and (b) to estimate the internal rates of return on the investment in pasture research in these regions. The technique used was the estimation of input-demand functions for the stock of improved pastures. It is shown that the important research results were mainly the result of research in plant nutrition. Adoption lags were estimated, and these were short by comparison with those usually derived by other methods. Internal rates of return calculated for successful research findings were very high, hut there were important differences between regions.

AGRICULTURAL DEVELOPMENT IN THE WEST OF IRELAND:  A MARGINAL PRODUCTIVITY STUDY
Provedor de dados: 31
Autores: Reidy,   James A.
This paper focuses on the impact of economic and demographic variables on agricultural productivity.  The purpose of this study was to examine resource productivity on farms in selected areas of County Mayo.  The returns to land, labor, livestock investment, and variable nonlabor costs were examined for possible resource misallocation.  The impacts of age of decision maker and family size on gross output were also studied.  Knowledge of the productivity of resources used in the production processes of farmers in County Mayo should be of interest to the farming community, extension agents, banks and lending agencies, policy makers, and all concerned with the development of agriculture in the west of Ireland.

THE INTEGRATED USE OF SIMULATION AND STOCHASTIC PROGRAMMING FOR WHOLE FARM PLANNING UNDER RISK
Provedor de dados: 31
Autores: Trebeck,   David B.; Hardaker,   J. Brian.
Methods of whole-farm planning under risk are briefly reviewed, noting especially associated operational problems. A planning problem relating to spatial diversification of beef production in the Clarence region of N.S.W. is investigated using a model comprising both simulation and linear programming components. It is concluded that such composite models are valuable for the analysis of sequential stochastic decision processes not presently amenable to solution by stochastic programming alone.

TECHNOLOGICAL CHANGE IN THE ARID ZONE OF NEW SOUTH WALES
Provedor de dados: 31
Autores: Duncan,   Ronald C.
The results described challenge the generally accepted interpretation of the factors underlying the changes in sheep numbers in the arid zone of New South Wales. The extent to which long-run changes in rainfall have been ignored is highlighted. Estimates of output per man are derived, using the C.E.S. production function, which show that there has been a small positive rate of technological change. Three-quarters of such technological advance has been due to factors which affect numbers of sheep carried, the remainder due to factors affecting wool production per sheep.

Autores: Shane,   Mathew.
This paper discusses the major problem facing regional capital and credit markets in their relationship to regional development. There are two ways in which capital and credit markets play a crucial role in regional development: (1) they mobilize local savings resources and allocate them between sectors and industries within the region and (2) they provide the mechanism by which financial resources flow between the region and the national economy.

SOME ECONOMIC ASPECTS OF UPLAND DEVELOPMENT IN KOREA
Provedor de dados: 31
Autores: Sjamsu,   Asmarni.
Korea is a land-short economy faced with a very high population density and low land cultivation density and high rates of migration from farm to urban areas with rapid urbanization.  Therefore, agricultural land is one of the valuable resources for the Korean economy.  Shortage of land has been one of the major limitations of production in the Republic of Korea in trying to produce enough food to supply its expected demand.  Population growth is one of the major factors in determining this demand for food.  Currently, about 60 percent of the population still derives its likelihood from agriculture.  Agriculture sector contributes about 28.4 percent of the GNP.

A MULTIPLE REGRESSION ANALYSIS OF ASPARAGUS PRICES IN MICHIGAN:  1956 TO 1970
Provedor de dados: 31
Autores: Yiemphat,   Nualsri.
Michigan ranks among the top five asparagus producing states in the United States; ranking forth in production, and second in its seasonal group.  As of 1970, the five leading states in asparagus were: (1) California, (2) New Jersey, (3) Washington, (4) Michigan, and (5) Illinois.  Although the total acreages employed for asparagus production has been decreasing -3,800 acres between 1969 and 1970 -Michigan's has been increasing - 900 acres for the same period.  The marked decrease in asparagus production over the past decade may be explained by strong foreign competition, especially from Taiwan since 1964; and from competing enterprises in certain areas and from asparagus farms sharing in the natural attrition of all farms in the U.S.  The objective of...

IMPACT OF LATIN AMERICAN INTEGRATION ON THE ECONOMIC DEVELOPMENT OF COLOMBIA
Provedor de dados: 31
Autores: Pelaez,   Eduardo.
The industrialization process began in Latin America as a way to promote economic growth, and at the same time to save foreign exchange.  Import substitution policies were adopted in almost every Latin American country.  High tariffs and other import restrictions were adopted in order to protect the infant industries.  Tax exemptions and other incentives were created in order to promote domestic and foreign investments.  While the process of import substitution continued, there were increasing needs for the importation of intermediary and capital goods,  Under these circumstances, the Latin American countries initiated programs of regional integration.  In 1958 the Central American Isthmian countries, except Panama, created the Central American Common...

INTER-GENERATIONAL TRANSFERS IN THE RURAL SECTOR: A REVIEW OF SOME PROBLEMS
Provedor de dados: 31
Autores: Longworth,   John W.
Three kinds of inter-generational transfer are discussed. Despite the obvious advantages of partnerships and other forms of income splitting from the income tax viewpoint, about half of the primary producers in Australia continue to operate their businesses as sole traders. Some of the problems which arise with partnerships, trusts and companies in this regard are considered. The transfer of the ownership of the assets in addition to the ownership of the income stream they generate, is then considered in detail. The taxation of this transfer by means of gift and death duties raises many questions in relation to economic equity and efficiency. The third type of inter-generational transfer discussed in this paper is the transfer of the managerial role....

LAND TENURE IN THE CYPRESS PINE AREAS OF NORTH-WESTERN NEW SOUTH WALES
Provedor de dados: 31
Autores: Sinden,   Jack A.; Kingma,   Onko Tjerek.
In New South Wales there are one million acres of land bearing cypress pine and held under lease from the government. This land is suitable for the joint production of timber and livestock or for timber production alone. Alternatively, the timber can be harvested to provide capital for property development. Farm management plans have, however, been constrained by the land tenure policy which aims to promote both closer settlement and timber production. In this paper the opportunity costs of the current tenure system are evaluated against the freehold situation. The conditions which favour either specialized timber production or the joint production of timber and livestock are examined. Finally, the cost of achieving a timber production target is examined...

FOOD-GRAIN MARKET EVALUATION IN NICARAGUA:  THE RICE CASE
Provedor de dados: 31
Autores: Navarro,   Luis A.
Like most of the Latin American countries, Nicaragua bases its economy largely within the agricultural sector.  Throughout history, the agricultural sector of Nicaragua has followed a tortuous path, which explains in part the pattern of a slow development process and the final relationship between GDP growth and the export activity.  Long before Nicaragua's independence, maize, tobacco, sugar, and cacao represented the most important crops, in the production of which almost the entire rural population was engaged.  The period between the independence from Spain in 1821 and 1857 was characterized by a political transition, in which Nicaragua left the Central American Federation and went into the struggle between the two existing political parties, Liberals...

THE ECONOMICS OF RICE POLICY IN FOUR DEVELOPED NATIONS
Provedor de dados: 31
Autores: Houck,   James P.
The purpose of this paper is to present and discuss the economic core of the protective rice policies in four major developed nations; the United States, Australia, Japan, and the European Economic Community (EEC). The fundamental economic aspects of rice policies are emphasized and not their operational details and statistics. The main purpose is to show how these policies protect domestic rice producers and to suggest how they may impinge upon world trade. The analytical tools are simple economics of static partial equilibrium together with some discussion of the economic and political setting within which the policies function.

Supply Projections for the Australian Beef Industry
Provedor de dados: 31
Autores: White,   B.J.
Between 1968 and 1971 beef cattle numbers in Australia expanded by 38 per cent compared with an increase in production of about 14 per cent. This paper presents projections to 1976 for beef and veal production. The projections indicate an expansion of 70 per cent in beef production by 1976 and are not sensitive to assumptions about the future rate of increase in cattle numbers. Supplies available for export will approximately double unless there is an increase in domestic consumption. It is concluded that the increased supplies will result in considerable downward pressure on beef prices unless export outlets expand more rapidly.

SOME CIRCUMSTANCES IN WHICH PRICE STABILIZATION BY THE WOOL COMMISSION REDUCES INCOMES
Provedor de dados: 31
Autores: Tisdell,   Clement A.
Stabilization of wool prices (which is partially achieved by the Wool Commission) may reduce the average annual net income (surplus) of growers and also of manufacturers of wool. The argument that the surplus of growers may be reduced is based upon Massell's extension of Oi's hypothesis. The possibility of falls in the surplus of manufacturers if wool prices are stabilized has a different basis. If wool prices are stabilized by buffer stocks, manufacturers find that their supplies are more variable than in the absence of controls. Consequently, they experience greater average annual cost if their marginal operating costs are increasing. Unless there are substantial revenue gains to processors, their surplus falls. The argument is also applicable to buffer...

A method is outlined which augments and modifies the Logan and King optimum solution of the processing plant location problem to give a number of near optimum solutions. Policy-makers can then consider jointly the comparative costs of alternative locations and their comparative noneconomic benefits. A Western Australian example involving the location of wool assembly and sampling centres is used to illustrate the method.

EVALUATION OF THE EFFICIENCY OF RESOURCE USE ON FARMS AND THE WELFARE OF FARM PEOPLE
Provedor de dados: 31
Autores: Standen,   B.J.
Studies evaluating efficiency of resource use on farms and farmer welfare have commonly failed to specify the precise nature of problems often described in terms such as 'low-income'. Hence superior, alternative welfare and resource use positions, of interest to the policy formulator, are inadequately specified. Additionally, criteria used in these studies have often been invalid or inappropriate. This paper examines the theoretical and operational bases of efficiency and welfare criteria.

RISK AND FARM SIZE IN THE PASTORAL ZONE
Provedor de dados: 31
Autores: Anderson,   Jock R.
Variable performance over time is an important feature of wool growing in the eastern pastoral zone of Australia. An analysis of time series data from the Australian Sheep Industry Survey indicates that standard deviation of net farm income is related more or less linearly to size of firm and increases with size at about the same rate as does average net income. A tentative conclusion is drawn that large farms have had a slight tendency to experience less variable rates of return than small farms. However, it is found that farms that have experienced relatively variable returns have tended to enjoy average rates of return above those of other farms of similar size.

The main objective of this paper is to critically examine the GOPEC's evaluation of the peasant colonization segment of the GOV program, "the core of the problem that this committee was called upon to report".  This examination is intended to ascertain whether the benefit-cost assessment of the GOPEC was, in fact, correctly executed, and to see whether the main policy conclusion of the GOPEC with regard to peasant colonization - that "policy makers take a long, hard look at the advisability of diverting resources to what is essentially a social welfare function in an economy where the greatest need is to maximize production" - follows from the GOPEC's analysis.  The second objective is to determine whether benefit-cost analysis was adequate for providing...

Provedor de dados: 31
Autores: Vere,   David T.
The use of a linear programming model for the determination of least-cost feed mixes for the drought maintenance of dry adult sheep is reported in this paper. A ration is suggested whereby sheep can be fully maintained at an approximate cost of one cent per head per day, representing a considerable reduction in the cost of feeding by the currently recommended standards. The importance of including the mineral additives, salt, sulphur and calcium is stressed throughout.

Economies of Size in Wheat Production
Provedor de dados: 31
Autores: Longworth,   John W.; McLeland,   W.J.
This paper investigates the relationship between the cost of producing wheat and the size of the wheat enterprise on farms in the Boolooroo Shire of New South Wales. The impact of seasonal variation and new technology on the cost/size relationship is also examined. The estimated longrun cost functions suggest that significant cost economies may be achieved as the area sown to wheat on a farm in the region concerned is increased to approximately 1,000 acres.

Provedor de dados: 31
Autores: Zegge,   Barnabas K.
Generally, economists have analyzed development planning in developing countries (LDC's) under the following aspects.  First, attention is focused on the plan strategies, policies and targets.  Special emphasis is often devoted to whether the targets have been or could be achieved over the relevant time periods.  Secondly, in recent years attention has also been given to the techniques of planning.  The purpose of this paper is to analyze the agricultural development planning process adopted in the Tanzania's Second Five Year Plan for Social and Economic Development, 1969-74.

Sinopse Foram encontradas concentrações isotopicas diferentes nas águas do Rio Negro e do Rio Solimões. Partindo daquela verificação preliminar, foi feita a amostragem sistemática de águas daqueles dois rios e do rio Amazonas, procurando-se determinar abaixo da confluência dos mesmos, o local onde o rio Amazonas apresenta uma estrutura horizontal e vertical homogênea traduzindo perfeita mistura das águas dos rios formadores. Os dados obtidos permitem também o cálculo, com razoável precisão, da vasão relativa de ambos os rios para alguns meses. Verificou-se que a 120 Km da confluência do Negro e o Solimões, ainda não havia mistura perfeita e que abaixo daquele ponto, a confluência do Madeira introduz perturbações na mistura. O grau de mistura em diferentes...

Abstract Birds that prey on arthropods flushed by army ants north of the eastern Amazon were studied at Serra do Navio and Reserva Ducke (Brazil) and at Nappi Creek and Bartica (Guyana). Regular ant-followers are two medium-sized antbirds (Percnostola rufifrons and Gymnopithys rufigula) and two smaller ones (Pithys albifrons and Hylophylax poecilonota), plus five woodcreepers of differing sizes (from very large Hylexetastes perrotti through Dendrocolaptes picumnus, D. certhia, and Dendrocincla merula to medium-sized Dendrocincla fuliginosa). Four other regular ant-followers occur in the region but were not found at the study areas. Forty-five species of casual or nonprofessional ant-followers, including 16 antbirds, 5 woodcreepers, and 5 manakins, also...

Weekly water-loss from Spherical Water-loss Integrators on a Clearing and below Secondary Growth in Central Amazonia ()
Provedor de dados: 36
Autores: Brinkmann,W. L. F.
Abstract: Spherical ceramic bulbs were set up as weekly water-loss integrators on a clearing and below a 2 year-old Cecropia-commumty at Km 18 of the Manaus-Itacoatiara Road. The instruments worked well in distinguishing the particular responses of individual sites to the impact of atmospheric agents as solar radiation, air temperature, air humidity and wind. Water-loss was primarily dependent on the order of magnitude of the weekly total of solar radiation and the presence or lack of a standing crop. Already a scarce secondary growth will reduce the weekly amount of water lost to the atmosphere considerably. Shelter-wood, however, considering the crop specific demands if introduced to tropical agriculture would provide favourable conditions as far as the...

Autores: Brinkmann,W. L. B.
Abstract The light intensity below the surface of Lago Castanho was recorded at 10 minute intervals and compared to the total light intensity above the water surface. Scattered light of the lake water was rather constant and it was found to be sufficiently high to support the growth of photoautotrophic organisms in the near-surface layer. Below the floating plant communities scattered light was extremely low in intensity.

Provedor de dados: 36
Autores: Machado,Paulo de Almeida.
Sinopse São estudados casos de blastomicose de Jorge Lobo encontrados entre índios Caiabí vivendo numa aldeia nativa à margem do rio Tatui (Amazônia Mato Grossense). Aqueles índios não devem ser confundidos com os Caiabí estudados por outros Autores no Parque do Xingu. Foram encontrados cinco quadros dermatológicos distintos e que o Autor divide em dois grupos polares: um grupo hiperêrgico (formas maculosas e gomosas) e um grupo hipoergico, forma queloidiforme. É enfatizada a conveniencia do estudo da classificação das formas clínicas, já proposta por D. Silva, como elemento básico para melhor interpretação das diferentes observações e como ponto de partida para pesquisas imunológicas indispensáveis à melhor compreensão da Doença de Jorge Lobo.

Determinação do boro, solúvel em ácido, em fertilizantes
Provedor de dados: 43
Autores: Alcarde,J. C.; Catani,R. A.; Souza,O. S.
O presente trabalho relata os estudos desenvolvidos sobre alguns aspectos do método volumétrico de determinação do boro, solúvel em ácido, em fertilizantes. Foram objeto de estudos a influência dos ions amônio e fosfato e suas consequentes eliminações, a possibilidade da redução da massa de manitol necessária para a titulação, face a mudança do pH do ponto final e a precisão e a exatidão do método. Os resultados permitiram estabelecer que 6,0 g de manitol são suficientes para a referida determinação pelo método proposto. A influência do íon amônio é evitada pela fervura da solução alcalina por 30 minutos e o ânion sulfato influe na precipitação do fosfato com Pb2+, sendo por isso, necessário 1 ml da solução de Pb (nO3)2 a 10% para cada 1% de P2O5 da...

Efeitos do ácido 2-cloroetilfosfônico na maturação de frutos do tomateiro (Lycopersicon esculentum Mill. cv. 'São Sebastião')
Provedor de dados: 43
Autores: Castro,Paulo R. C.; Churata-Masca,Manoel G. C.; Awad,Marcel.
Estudou-se a influência do ácido 2-cloroetilfosfônico (ethephon), aplicado em pré-maturação, na frutificação do tomateiro de crescimento indeterminado, cultivar 'São Sebastião'; em condições de casa de vegetação. Pela análise da produtividade verificou-se que o regulador de crescimento acelerou significativamente a maturação dos frutos, incrementando o peso e o número total de frutos por planta obtidos nas primeiras colheitas, sendo isto compensado por diminuições significativas em colheitas posteriores. Não observou-se porém, diferenças significativas no peso e número de frutos por planta, considerando a totalidade das colheitas, entre o controle e as plantas tratadas com 1000, 2000 e 4000 ppm de ethephon.

Nota sobre ácaros (Acari) atacando fruteira-do-conde (Rollinia sp.)
Provedor de dados: 43
Autores: Flechtmann,Carlos H. W.
The flowers of this orchard tree presents six fleshy petals, fused two by two, and disposed propeller like. In the center is a cavity which harbors the cone shaped reproductive organs. An eriophyid mite, described by H. H. Keifer as Aculops flechtmann Keifer, 1972, causes considerable bronzing to the petals (Fig. 1-A). Large numbers of this mite attacking the basis of the reproductive organs causes them to dry and drop. On the young fruits, which are squamous, this mite causes some rusting and small necrotic areas (Fig. 1-B). As the fruit grows these small areas remain dark and barky. Very often the necrotic areas are invaded by the false spider mite Brevipalpus phoenicis (Geijskes, 1939), which enlarges the damage. The false spider mite also attacks...

Autores: Alcarde,J. C.; Ponchio,C. O.
O presente trabalho descreve os estudos efetuados sobre alguns aspectos dos métodos espectrofotométricos de absorção atômica, empregados na determinação do zinco e cobre em fertilizantes. Assim, foram objeto de estudos o efeito da acidez da solução da amostra, a influênca dos ânions fosfato, sulfato e nitrato, em função da acidez da solução da amostra, a durabilidade das soluções padrão e a precisão e a exatidão dos métodos. Os resultados permitiram concluir que a absorbância das soluções padrão de zinco e cobre não é afetada pela concentração de HC1, podendo esta variar de 0,1 N a 0,5 N e que os referidos métodos não sofrem a influência dos ânions fosfato, sulfato e nitrato, em qualquer concentração de HC1 dentro do intervalo entre 0,1 N e 0,5 N....

Autores: Bulisani,Eduardo A.; Miyasaka,Shiro; Almeida,Luiz D'Artagnan de; Scaranari,Hélio J.; Pinto,Hilton S.
Em ensaio iniciado em março de 1969, na Estação Experimental de Jundiaí, SP, foram estudados os efeitos da incorporação de massa vegetal, proveniente de leguminosas e de gramínea, e do sombreamento parcial, simulando o plantio consorciado com milho, na cultura do feijoeiro. Determinou-se para culturas "apleno sol" e "sombreada" a temperatura do solo a 2 e 10 cm de profundidade. Observou-se efeito favorável da incorporação de massa vegetal ao solo imediatamente antes do plantio do feijoeiro. Os tratamentos que receberam incorporação de massa vegetal produziram mais sementes de feijão, o que os torna estatisticamente superiores aos tratamentos que não receberam tal prática. Nessas mesmas condições o sombreamento parcial não interferiu na temperatura...

Estudo comparativo da resistência do fio de algodão obtido em fiação piloto e em fiação industrial
Provedor de dados: 53
Autores: Lazzarini,José Fernando; Sabino,Nelson Paulieri.
O estudo de 81 pares de valores de resistência do fio de algodão 22/1 produzido em fiação piloto (X) e em fiação industrial (Y) mostrou que entre os dois processos existe uma correlação r= 0,563**. A equação de regressão é da forma Y= 611,631 + 0,486 X. Ficou demonstrado que equações calculadas para nove linhagens em cada localidade fornecem estimativas mais precisas da resistência do fio do que a equação geral. O coeficiente de correlação mais alto (r=0,924**) foi encontrado para a localidade de Campinas.

Resistência ao mosaico Y, combinada com resistência ao mosaico comum, em tomateiro
Provedor de dados: 53
Autores: Nagai,Hiroshi; Costa,A. S.
Derivados de tomateiro, que incorporam resistência ao vírus de mosaico Y (PVY) e mosaico comum (TMV), foram obtidos do cruzamento entre a var. Ângela, resistente às estirpes locais do vírus de mosaico Y, e T 15-1-6-1, que é altamente resistente às estirpes locais do TMV, por meio de inoculação com dois vírus, retrocruzamentos para Ângela e seleção de gerações avançadas do híbrido. Tipos selecionados do tomateiro são homozigotos para os gens Tm-2ªe rt. Suas características comerciais são semelhantes às da var. Ângela. Espera-se que os novos tipos de tomateiro reduzam perdas causadas pela infecção com PVY e/ou TMV, evitem efeitos sinérgicos entre dois vírus em combinação, eliminem a infecção do tipo "internal browning" e também transmissão do TMV pelas...

Autores: Monaco,L. C.; Carvalho,A.
Como parte essencial do melhoramento do cultivar Guarini de Coffea canephorae de plantas pertencentes aos cultivares Bangelan e Uganda de C. congensis,procurou-se determinar as combinações compatíveis através de cruzamentos entre essas espécies e dentro das espécies, utilizando pólen de plantas individuais ou mistura de pólens. Os cruzamentos foram realizados em 1971, avaliando-se as porcentagens de pegamento dos frutos em 1972. De um modo geral os dados mostram porcentagem baixa de frutificação. Verificou-se para o Guarini, que a compatibilidade mais generalizada ocorreu com a mistura de pólen do Robusta, do Laurentii e das introduções 1028, 1029 e 1031. Entre as plantas desse cultivar, verificou-se pegamento apenas entre os cafeeiros G 1 com G 11 e G 12,...

Poliploidização em berinjela (Solanum melongena L.): I - Tratamento de sementes pela colquicina
Provedor de dados: 53
Autores: Medina,Dixier M.; Longo,Catalina R. Lopes; Cruz,Neusa Diniz da; Azzini,Luiz E.; Usberti Filho,J. A.
Com o objetivo de conseguir plantas poliplóides de berinjela, foram realizados em 1970 alguns tratamentos com colquicina em sementes do cultivar Santa Genebra. Três séries de tratamentos foram efetuadas, era-pregando-se soluções de diferentes concentrações, variando a duração do tratamento e também seu momento de aplicação, isto é, antes, durante e até a germinação. O número de cromossomos nas raízes e o número de estornas do material tratado, quando comparados com o original diplóide, indicam que a completa poliploidização não foi conseguida. O máximo que se constatou até o estádio de desenvolvimento em que foram levadas as observações, foram plantas quiméricas, tanto na parte aérea como nas raízes, provenientes dos tratamentos de sementes em germinação e...

Poliploidização em berinjela (Solanum melongena L.): II - Observações em plantas resultantes de tratamentos com colquicina
Provedor de dados: 53
Autores: Medina,Dixier M.; Cruz,Neuza Diniz da; Longo,Catalina R. Lopes; Conagin,Cândida H. T. Mendes; Azzini,Luiz E.
As observações de diversos caracteres morfológicos em plantas de berinjela (Solatium melongena L.) provenientes de tratamentos com colquicina levaram à separação de razoável número de possíveis poliplóides. O número de cromossomos determinado em células-mães de pólen revelou a existência de plantas tetraplóides e plantas quiméricas, além das normais diplóides. Numa amostra representando os diferentes tratamentos, encontrou-se uma associação quase perfeita entre a natureza tetraplóide ou quimérica da planta e a irregularidade do tamanho do pólen; tal associação não foi encontrada quando se analisou a quantidade de pólen vazio. Os frutos tetraplóides obtidos produziram sementes maiores e em número bem menor que os diplóides de pesos equivalentes.

Estudou-se a eficiência de diferentes frações granulométricas de materiais corretivos da acidez do solo, empregando dois tipos de calcário, dolomítico e calcítico, num ensaio conduzido em vasos, em casa de vegetação, sem utilização de planta como teste. Aos 35, 100, 270 e 540 dias após a administração do calcário, era o solo amostrado e analisado em seus teores de pH, alumínio, cálcio e magnésio. Os resultados mostraram que a granulometria do material exerce considerável efeito na sua ação, e que os calcários com grau de finura abaixo de 50 "meshes" (0,297 mm) foram tão eficientes quanto os de granulometria mais fina. O tempo de contato do material com o solo parece não influir na ação do calcário, já que aos 35 dias apresentou os resultados esperados....

Autores: Gargantini,Hermano; Feitosa,Celi T.; Igue,Toshio.
Em casa de vegetação conduziu-se um experimento com trigo, em vasos com Latossolo Vermelho Escuro orto, proveniente do município de Itapetininga, com o objetivo de verificar o comportamento de diversos adubos fosfatados, sob três condições de acidez do solo. Foram estudadas as adições de 0, 100 e 200 kg/ha de P(2)0(5), em presença e em ausência de calcário. Os fertilizantes usados foram superfosfatos simples e tripo, termofosfato, fosfato de diamônio e apatita-de-araxá, sempre em presença de nitrogênio e potássio. Os resultados mostraram efeito significativo para doses de calcário, tanto para peso seco de plantas como para peso seco de grãos. Entre os fertilizantes, o superfosfato simples e o termofosfato foram os que melhor se comportaram para peso de...

Adubação do trigo: IV - Experiências com N, P, K e S em solos de várzeas do Estado de São Paulo
Provedor de dados: 53
Autores: Camargo,Carlos Eduardo de Oliveira; Rocha,Túlio Ribeiro.
Em 1971, em solos de várzeas anteriormente cultivadas com arroz, foram realizados dois ensaios de adubação N, P, K e S em culturas de trigo (Triticum aestivum L.): um na Estação Experimental de Mococa e o outro na Companhia Colonizadora Jamic, em Guatapará, ambas no Estado de São Paulo. Os dados obtidos mostram grandes efeitos do nitrogênio, e pequenos do fósforo e do potássio. No ensaio de Guatapará houve boa resposta ao tratamento com enxofre, em relação à testemunha, porém no ensaio de Mococa o efeito do enxofre foi negativo e significativo estatisticamente. Foram calculadas as quantidades de nitrogênio e de fósforo necessárias para a obtenção de maior lucro por área para as relações de preços entre N e P = 1,5:1 e 1:1, considerando-se fixa a dose de 30...

Efeitos da colquicina em Arachís hypogaea L.
Provedor de dados: 53
Autores: Conagin,Cândida H. T. M.
A aplicação da colquicina no amendoim comum (Arachis hypogaea L.) foi realizada com a finalidade de obter mutações, das quais as favoráveis seriam utilizadas no programa de melhoramento. Observações sobre o número de cromossomos revelaram que houve duplicação em algumas células das raízes, sendo estas polissomáticas, do nível tetraplóide-octoplóide; houve também formação de grãos de pólen maiores e desiguais em algumas plantas; a parte aérea não apresentou nenhuma evidência de poliploidia. Independentemente da variação dos grãos de pólen e da polissomatia das raízes, modificações fenotípicas foram observadas, das quais destacam-se as plantas de fenótipo semelhante ao Arachis monticola,pelo interesse científico, e as sementes maiores e mais regulares, pelo...
