Contribution a l'étude du pétoncle (Chlamys varia L.)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Letaconnoux, Robert; Audouin, Jacques.
The scallop Chlamys varia L. is a common shellfish of the Atlantic coast, a little rarer in the English Channel. It forms large banks in the roadstead of Brest and in the area of La Rochelle, along the north-eastern coast of the Isle of Ré, as well as between the Isle of Oléron and the continent. Some very depopulated banks can still be found in the Arcachon Bay and in some parts of the Mediterranean coast.Near La Rochelle, scallops are fished by boats using drags with an opening of 1 m and a round leading edge. It is limited to two hours per day from November to March, in order to protect the stocks. Sixty to eighty small motor boats or sardine boats take part in this fishery, catching around 800 tonnes per year, that is to say half the production of the...

Préparation des collecteurs - tuiles : un essai de lutte contre la fixation des salissures
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Le Dantec, Jean.
Les ostréiculteurs du bassin d'Arcachon utilisent pour la récolte du naissain des tuiles demi-cylindriques d'une surface voisine de 17dm2. Elles sont traditionnellement recouvertes d'un enduit dont la composition est très variable. La "baille à mortier" permet de traiter 1.000 tuiles. Voici deux exemples concrets du mélange utilisé.

Contribution a l'étude des xylophages marins

Autores: Deschamps, P.
These first results might clarify some problems linked to the biology of tarets and other small lignivorous crustaceans. The systematic of the molluscs Teredinidae, so complex, is only based on the study of pallets, which is a great source of confusion when one has to examine the woods after the molluscs' death. We tried to distinguish the species by examining the striates and denticulations on the shelves. The size of the intervals between the striates and the proportional size of the denticulations, as well as the shape of the denticulation marks of the middle part, can indeed allow us to differentiate between some species.

Acclimatation du clam (Venus mercenaria L.) en Bretagne
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Marteil, Louis.
Large quantities of clams (Venus mercenaria L.) from the U.S.A. have been introduced in Brittany since 1930. Stopped in 1940, their importation started again in 1954. These shellfishes, designed to be immediately sold for eating, only stayed for a short period of time in the ponds and farms of the Belon, Pénerf and Etel rivers, or in the Gulf of Morbihan, where they were stocked. However, some individuals managed to escape the fisheries and stayed buried for years where they had been sown. Lambert (1949) reported how some twenty year-old clams were found on a farm on the Etel River. In some ponds of the Gulf of Morbihan and the Pénerf river, one can still find clams which have been stocked there before 1940: their size is huge and reaches 10 to 14 cm, and...

Phytoplancton et contenus stomacaux d'huîtres portugaises, (Gryphaea angulata Lmk) dans le bassin d'Arcachon
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Le Roux, Suzanne.
The diet of lamellibranches is one of the main issues raised by oyster culture. Numerous scientists tackled this problem from different points of view: elements from the stomachal content at different times of the year, ingestion mechanisms, influence of hydrological factors on the ciliary activity, and provided some interesting results though often contradictory, at least from the outside.This preliminary study aims to demonstrate:l. - The part of phytoplankton in the stomachal contents of Portuguese oysters (examinations based on the autumn and winter months because of their richness in diatoms and mostly because of the dominance of these latter on the animal elements found in the plankton),2. - The difference in the diet caused by the raising of the...

La pêche du thon a l'appât vivant en Californie
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Doutre, M.
From February 22nd to April 2nd, 1956, we studied tuna fishing with live bait, as practiced by "tuna-clippers" from the Californian harbour of San Diego. This fishing deals only with two species: the albacore, "yellowfin Tuna" (Neothunnus macropterus) and the skipjack (Katsuwonus pelamis); little tunnies, "black skipjacks" (Euthynnus alleteratus), can also be found, either within an albacore or skipjack shoal, or by themselves. When these fishes are caught, they are either thrown overboard or used as bait (fig, 1). The lower limit weights for these two commercial species are respectively 3.400 kg for albacores and 1.800 kg for skipjacks. Yellowfin tuna can reach weights of up to 180 kg; but these catches are pretty unusual and the average weight is 13 to...

La fixation en claires des larves de l'huître plate Ostrea edulis
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Trochon, Pierre.
La reproduction des huîtres plates dans les claires de la région de La Tremblade a été étudiée à partir de l'année 1953. Les premières observations permirent de constater dans ces plans d'eau la présence de larves en grand nombre au début de l'été ; mais la quantité des larves parvenues au stade de fixation demeurait toujours très faible. Néanmoins, sur des collecteurs immergés aux moments les plus favorables, de très faibles fixations furent obtenues. Il était donc démontré qu'il était possible de récolter des huîtres plates dans ces bassins.

Autores: Doutre, M.
From September 22nd to December 19th, 1955, five research agencies collaborated in the study of Pacific, Central and Eastern waters. The vessel "Hugh M, Smith" belonging to the "Pacific Oceanic Fishery Investigation", recorded physical, chemical and biological information on the area crossed by the Equatorial current between longitudes 158° W and 105° W. A unit of the Peruvian fleet gathered information on the northern boundary of the Humbolt current, next to Ecuador. Two vessels from the "Scripps Institution of Oceanography" (University of California), the "Spencer F. Baird" and the "Horizon", focused on the area located between meridian 125° W and the American continent. The "Scofield" of the Fish and Game of California later joined the fleet.

Contribution a l'étude de quelques sédiments marins et de récifs d'hermelles du mont Saint-Michel
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lucas, G.; Lefevre, P.
In a note addressed to the Academy of Sciences, Galaine and Houlbert (29) underlined the importance of the reefs built by the Hermelles (Sabellaria alveolata) in the Bay of Mont Saint-Michel. Looking at a summary of the history of these buildings, we learn that, as early as 1832, Audoin and Milne-Edwards knew, "on the shores of the Mont Saint-Michel and northeast of the Pas-aux-Boeufs, sand banks or islets" made of Hermelles tubes (uncovering at low tide and of a height of around 8 to 10 feet). Galaine and Houlbert saw in these reefs one of the causes of the silting of the Bay, and of the changing of the Couesnon bed since 1790. In their opinion, these reefs had grown from 8 to 10 feet in 1823, to 5 to 6 metres (15 to 18 feet) in 1916. [...]

[...] In this work, we aimed to describe a "clipper" in detail: the vessel, its gear and fishing techniques. Its sophisticated gear, which is the result of a long experience in specific conditions, deserved to be looked at, especially since fishing with living bait (and the example of California) is becoming more and more popular.

Autores: Kurc, Georges.
Depuis 1951, l'Institut des Pêches maritimes a procédé à des lancers de flotteurs au cours des campagnes océanographiques du « Président-Théodore-Tissier ».   Ces flotteurs sont des « bouteilles dérivantes » ovoïdes, demi-Perrier (fig. 1).   Les bouteilles dans lesquelles on a introduit une carte postale représentant schématiquement l'Atlantique nord et indiquant la position et la date de lancement (fig. 2) sont lestées avec du sable et bouchées. L'étanchéité du bouchon de liège est assurée par un mélange de paraffine et de cire fondues dans lequel on plonge le goulot de la bouteille.   Plusieurs milliers de flotteurs ont été jetés à la mer en 1951, 1952, 1954. Cette méthode n'est pas entièrement satisfaisante, mais elle ne l'est pas moins que toutes...

Sur la présence d'ebriédiens dans le plancton de la baie de Pointe-Noire (A. E. F.)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Rossignol, M.
The Ebridians, marine planktonic flagellates with an internal siliceous skeleton, used to be very numerous in the Tertiary era but are only represented nowadays by two genera: "Ebria" Borgert (1891) and "Hermesinum" Zacharias (1906). Found successively in the Baltic Sea, the North Sea, the Mediterranean Sea, the northern Pacific Ocean, the northern and southern Atlantic Ocean, they had never been observed in tropical seas. Consequently, they were considered as cold or temperate water organisms. Their presence on the western African coast, at latitude 4° 48' S, in addition to extending their distribution area, seems to invalidate this point of view. Without drawing any hasty conclusion, it seemed interesting to recall their appearance in the Bay of...

Autores: Beauge, L.
Between latitudes 45°30' (Canso) and 52° (Belle-Isle) is a large depression in which recent glacial modelling left visible marks everywhere, in the runnels of the valley, in the rock bars and frontal moraines, in the deposits of the lateral moraine boulders. These marks sometimes make it difficult to approach the docks in which the small coastal villages used to unload the boats that used to sail back and forth to Quebec City for communication purposes and now transport pulpwood.

A l'embouchure de la Vilaine, rivière située aux confins du Morbihan et de la Loire-Inférieure, s'est développée depuis fort longtemps une industrie mytilicole prospère. La culture de la moule (Mytilis edulis L.) est pratiquée en bouchots sur une centaine d'hectares en aval du petit port de Tréhiguier en Pénestin. La production annuelle de ces parcs dépasse 2.000 tonnes; les produits des moulières naturelles qui bordent la côte servent à l'ensemencement des concessions. A l'intérieur de la rivière; il ne subsiste plus rien des gisements mouliers qui jadis s'étaient établis ça et là, partout où la nature du fond le permettait.

Compte rendu d'essais pour la protection des bois contre les tarets
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Letaconnoux, Robert.
Among the organisms attacking submerged wood structures, ship worms play a predominant role. In one year, an untreated piece of wood can be totally invaded by these molluscs' galleries and lose more than 50 % of its weight. The hardest woods like azobé are easily attacked and there is no obvious advantage to building anything with such expensive materials. Impregnating wood with a toxic product can stop or delay the attack. As a consequence, a wood like pinaster, which can easily be impregnated, can have an equal or greater resistance than that of harder woods. Polychlorinated phenols stop or delay efficiently taret penetration but their action is increased when used with chlorinated hydrocarbons. In this case, the differences in protection seem to come...

Autores: Le Dantec, Jean.
Oyster boxes or "ambulances" were invented by Michelet in 1865: Two wooden frames (2 X 1 m), positioned on top of each other with a 15 cm interval, were attached with a hinge. Each frame was covered by a galvanized wire netting with relatively small meshes. The inside was divided into three compartments to avoid the piling up of oysters. These devices were set up on little stilts of 15 to 20 cm to isolate them from the floor. These pots enabled the development of detached oysters, mostly the flat oyster Ostrea edulis L., safe from predators. [...]

Une des plus importantes richesses marines de la rade de Brest est la coquille Saint-Jacques. Avant-guerre c'était un spectacle familier pour les Brestois de voir évoluer en hiver les voiliers à la recherche de ce mollusque très apprécié. Peu à peu, après la guerre. le nombre des voiliers a diminué pour faire place aux bateaux à moteurs; au début de la campagne 1951-1952 ces derniers étaient en nombre égal aux premiers et à la saison de pêche 1954-1955 la voile avait totalement disparu de la flottille. Les Pecten maximus sont capturés par les pêcheurs à l'aide de dragues de 1,80 mètre à 2,10 mètres de largeur, dont le maillage ne retient en principe que les coquilles ayant atteint la taille marchande, fixée à 8.5 cm pour la rade.

N, 48° limits, amongst others, the size of the mesh of mobile gear (stretched and wet) north of L. N, to 48° to 80 mm (provisionally 75 mm during the first few enforcement years). However, this measure applies uniformly to a series of commercial species with a different market size defined for each of them by the same agreement. Yet, if the 80 mm mesh works for the catch of species of high market size (cod, haddock, plaice), it is inefficient with species of small market size that swim easily through the mesh (whiting, flounder). As a consequence to this incompatibility between measures...

Three new ostracod species, each belonging to a new genus, were described by the first author (DE VOS, 1953). They had been found on the body and the legs of Limnoria lignorum, the well-known woodburrowing isopod. Since then, we have been looking for commensals in several new lots of European Limnoria, and in this way we obtained valuable new data on morphology and distribution of two of the three ostracod species described. Moreover, Dr. Robert I. MENZIES, La Jolla, California, kindly sent us a beautiful lot of ostracods from Limnoria tripunctata MENZIES, an isopod species from the Pacific coast of America, found in test-blocks placed at about 7 feet below mean tide level, and collected in the course of the marine wood-borer studies, Project NR 163—084 at...

Lardoglyphus zacheri Oudemans and L. (= H oshikadania) konoi (Sasa and Asanuma) were sent to me by Mr. D. A. Griffiths of the Infestation Control Division of the Ministry of Agriculture. They were found in butcher's offal ("gut greaves"), used in the manufacture of fertiliser, on premises near Chesterfield. In this particular case the offal was obtained locally, though it can also be imported from the Argentine; possibly the mites were orginally introduced into this country on empty uncleaned sacks obtained from other manufacturers.

Scientific research into the occurrence and population density of the Harbour Seal ( Phoca vitulina L.) in the coastal regions of the Netherlands, necessary for any efficacious nature conservancy programme, was started in September 1953 by the author. A reliable calculation of the total number of Harbour Seals in the coastal regions of the Netherlands soon proved to be extremely difficult. Estimations of the number of Harbour Seals occurring in these regions had been made several times before. BROUWER (1927) took the total number of seals in the Netherlands part of the Waddenzee at 1500 and the total number of seals in the estuaries of the provinces of Zuid-Holland and Zeeland at 800.

G., M. et Sch. bloeit tijdens de winterslaap van vele floristen en wordt daardoor veelal minder aandachtig bestudeerd dan andere indigenen van vergelijkbare algemeenheid van voorkomen. Het is daarom wellicht gewenst er aan te herinneren dat zij in twee uiterlijk nog al verschillende vormen voorkomt. Vrouwelijke planten hebben talrijke hoofdjes in een vooral in de vruchttijd lang uitgerekte bloeiwijze. De hoofdjes bevatten elk vele vrouwelijke bloemen, zonder meeldraden, met goed ontwikkeld vruchtbeginsel, een zeer lange stijl en twee draadvormige stempels. De bloemkroon bestaat uit een buis met niet of slecht ontwikkelde kroonslippen. Bovendien bevinden zich in het midden van het hoofdje één of meer steriels, schijnbaar...

Pendant les étés de 1953, 1954 et 1955 j’ai effectué des travaux de terrain dans le Massif des Trois Seigneurs, Pyrénées orientales, sous la direction du Professeur L.U. de Sitter. Ces travaux de terrain comprennent entre autres le levé d’une carte géologique de la partie centrale et Sud-Ouest de ce massif. Le Massif des Trois Seigneurs est un des massifs primaires Nord-pyrénéens, situé au Nord de la „Zone axiale” et entouré de sédiments mésozoïques. Le massif est constitué entièrement de roches paléozoiques. Il doit son nom au Pic des Trois Seigneurs (2199 m) le plus haut sommet de la région.

New bird records from Biak Island

Autores: Junge, G.C.A.
Mr. C. Hoogerheide, who was stationed at the Netherlands Naval Air Base at Biak Island between July 1953 and December 1954, brought together a small collection of birds, which was sent to the Leiden Museum. It is worth while to put on record those species, which have not been collected before on this island and to give remarks on a few other species. An excellent review of the avifauna of Biak Island is given by Mayr and De Schauensee (1939). Fregata ariel ariel (Gray) A ♂ imm. and a ♀ imm. have been collected by Mr. F. Heuberger at sea near the south coast of Soepiori between Korrido and the kampong Soëk on July 26, 1952. Through the intermediary of Dr. L. D. Brongersma the specimens were presented to the Leiden Museum. Near this island the species has...

Autores: Terlingen, H.; Bemmel, A.C.V. van.
The results of a complete census of the breeding population of the White Stork (Ciconia ciconia) in the Netherlands, carried out in the year 1950 by the State Forestry Service, have been published by MÖRZER BRUIJNS and BRAAKSMA in Beaufortia 5, Nr. 45, April 15, 1955, p. 23—42. A new census was performed during the year 1955 ; it is the intention to repeat the census from now on every year. The results of the last census are even more alarming than those from 1950 (see table, p. 113). The number of occupied nests decreased from 83 nests in 1950 to 58 nests in 1955. The number of fledged young decreased from 195 in 1950 to 96 in 1955. Many nests, still occupied in 1950, were either in a state that they could no longer be used or they had vanished altogether...

Notes on a collection of Crustacea Decapoda from the Great Bitter Lake, Egypt, with a list of the species of Decapoda known from the Suez Canal
Provedor de dados: Naturalis Digital Academic Repository
Autores: Holthuis, L.B.
Between August 18 and September 5, 1950, Dr. C. Beets, geologist Royal Dutch Shell Oil Company, explored the aquatic fauna and flora of the Great Bitter Lake. In the course of this exploration dredge hauls were made at 47 stations, distributed all over the lake. An account of this work and a description of the stations were given by Dr. Beets in a previous volume of the present journal (1953). The Decapod Crustacea collected by Dr. Beets belong to twelve species, three of which have not been reported from the Suez Canal before. Apart from these additions to our knowledge of the fauna of the Suez Canal, the present collection is of great interest because of the extensive data provided by Dr. Beets on the ecology of the localities from which the material...

Het aantal adventieven, dat wij tot nu toe in Friesland vonden, was zeer gering. Wel was ons bekend, dat in vroeger jaren op de terreinen van de Koopmans Meelfabrieken te Leeuwarden verscheidene (niet gepubliceerde) vondsten waren gedaan, maar het gelukte ons nooit daar enig spoor van terug te vinden. De direktie van de meelfabrieken was echter zo vriendelijk ons mee te delen, dat de graanverontreinigingen vervoerd werden naar het vuilverwerkingsterrein van de gemeente Leeuwarden, gelegen onder Wartena. In de nazomer van 1955 bezochten wij dit terrein voor het eerst en inderdaad bleken hier verscheidene adventieven voor te komen. Dat het terrein tot nog toe aan de aandacht van de floristen is ontsnapt, is ongetwijfeld te wijten aan de ligging. Men kan het...

The valid name of the Banteng: Bibos javanicus (d'Alton)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hooijer, D.A.
While studying the collection of recent oxen of the Museum my attention was drawn to the problem of the nomenclature of the Java banteng. I believe to have been able to clear up the confusion that still exists today, as will be set forth in the present note. The wild ox of Java, the banteng, is known variously as Bos sondaicus or Bos banteng, but neither of these is the earliest available valid name. The species should have been called: Bibos javanicus (d'Alton) B[os] Javanicus d'Alton, Skelete der Wiederkäuer, Bonn, 1823, p. (7), pl. VIII fig. c. The earliest reference to the banteng of Java I have been able to find is in Pennant (1800, p. 35): "Mr. Loten told me that wild oxen, of a reddish brown color, with vast horns, and of a great size, are found in...

A short survey of the American species of the genus Octohlepharum
Provedor de dados: Naturalis Digital Academic Repository
Autores: Florschütz, P.A.
During my studies of the Surinam specimens belonging to this genus my attention was drawn to the often wrong interpretation of several old species. To avoid future misidentifications it seems useful to give a short review of the American species that are known up till now. It is emphasized, however, that this paper does not have the pretension to be a monograph of the American species. For the greater part my study of the species was confined to the type material and the variability therefore is not known. However, this contribution may serve as a base for a future monograph of this interesting group. Attention is drawn to the fact that only older leaves of the plants should be studied, because the leaf apex of the younger leaves is in all species acute...

Notes on the Marantaceae of Suriname
Provedor de dados: Naturalis Digital Academic Repository
Autores: Jonker-Verhoff, A.M.E.; Jonker, F.P.
The list of Marantaceae published by PULLE (1906) comprises 20 species belonging to 6 genera, the largest genus being Calathea with 8 species. It was found, however, that one of the species does not belong to the family: investigation of the type of Calathea strobilifera (Miq.) Koern., viz. Kegel 1469 [GOET], showed that it pertains to Renealmia strobilifera Poepp. et Endl. (Zingiberaceae). The record of another species, Calathea allouia (Aubl.) Lindl. appeared to be based on a misidentification: the collection Focke 893 cited under this name by PULLE (1906) belongs to C. grandis O. G. Peters. Later on PULLE (1909) recorded the occurrence of one species more of this family in Suriname, viz. Myrosma polystachya Pulle, a new species. Since then no further...

Utricularia is represented in Malaysia by two main kinds of plant, i.e., aquatic and terrestrial. The aquatic species can again be divided into two main groups, those which float freely in still water and those which are more or less anchored in and beneath shallow water. All of the aquatic species consist of long branching stolons bearing leaves which are divided into capillary segments and traps. The racemes of small yellow, violet, or purple flowers arise from the stolons and project a few inches above the surface of the water. The terrestrial species (including a few which are epiphytic) consist of slender rhizoids bearing linear, spathulate or peltate leaves and traps.

In the collection of the Haifa Sea Fisheries Research Station, among material trawled in Mersin Bay, S. E. Turkey, two Brachyuran crabs were found which prove to be of great interest. One, Actaea rufopunctata (H. Milne Edwards), has a rather wide distribution in both the Atlantic and the Indo-West Pacific regions, but only very few records from the Mediterranean are known as yet. The other, Ixa monodi, a species of IndoWest Pacific origin, is new to science, while the genus to which it belongs is now reported for the first time from the Mediterranean. Actaea rufopunctata rufopunctata (H. Milne Edwards, 1834) (pl. IV fig. 1) An ovigerous female (cb. 20 mm) 1) was trawled in Mersin Bay in August 1954.

Bauxite deposits in Suriname and Demerara (British Guiana)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Kersen, J.F. van.
On the basis of the morphology and stratigraphic positions, the bauxite deposits in Suriname and Demerara (British Guiana) were divided into four main groups, namely: 1. Plateau type bauxite, 2. High-level type bauxite, 3. Medium-level type bauxite, 4. Low-level type bauxite. The age of these deposits is as follows: Plateau type bauxite .................................... Pre-Tertiary Low-level type bauxite ................................ Middle- to Lower-Tertiary High-level and Medium-level type bauxite .... Pleistocene These three main periods of bauxitization have led to the formation of fossil bauxite. After these main periods the bauxitization process, however, has not come to a standstill. It continues even at the present time, although less...

During the zoological exploration of Netherlands New Guinea sponsored by the Rijksmuseum van Natuurlijke Historie, Leiden, in 1954-1955, four specimens of Clausiliidae were found. There are no previous records of the occurrence of Clausiliidae in New Guinea; the most eastern locality in the Indo-Australian region from which this family of snails was known is the island of Halmahera, in the Moluccas (Loosjes, 1953, p. 209).

Notes on some Acanthaceous genera and species of controversial position
Provedor de dados: Naturalis Digital Academic Repository
Autores: Bremekamp, C.E.B.
The genus Stenandriopsis was created by S. Moore in Journ. of Bot. 44: 153. 1906 for a plant collected first by Vaughan Thompson and afterwards by Baron in an unspecified part of Madagascar. As the plate by which the description is accompanied depicts the specimen collected by Baron (n. 6708), the latter is to be regarded as the type. Stenandriopsis was referred by its author to the Justicieae, but this tribe is apparently accepted by him in the delimitation it received in BENTHAM and HOOKER’s “Genera Plantarum”, and as it is in this sense a most heterogeneous mixture, this does not greatly enlighten us. Of more importance is that Moore compares it with Crossandra Salisb. and Stenandrium Nees, i.e. with genera belonging to my subfamily Acanthoideae and...

Explanation of the geological map (Northwestern part) of the province of La Coruña, Galicia, N.W. Spain Main rock groups We distinguish five main groups of rocks which probably differ in age. Whether this age difference applies only to the time of their intrusion or metamorphism or also to their sedimentary origin remains obscure. These five groups are from top to bottom in the time scale: — (1) Younger rocks, mostly not tectonized, post tectonic. To this group belong: (a) a red sandstone patch west of Malpica on the coast, unconformable on the underlying schists, age unknown; (b) the Traba granite pluton and some other plutonic rocks south of it; (c) rhyolitic or syenitic dykes south of the Traba granite; (d) a swarm of WNW striking basic dykes, mostly...

Speculations on the Immigration of the Barnacle Elminius modestus in France
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hartog, C. den.
The literature on the recent immigration of the Australian barnacle Elminius modestus to West European coasts is rather exhaustive. The present author has given details on the exact centre of immigration on the Dutch coast. The spreading from this centre has been followed in subsequent years (DEN HARTOG, 1953). From the French coast only few data are known. The localities where it first established itself are unknown. Speculative though it may be, therefore, it seems useful to try a reconstruction of the immigration of Elminius in France as exact data are still available. In July 1951 the author found Elminius on the Boulonnais coast (Pas de Calais: Le Portel, Boulogne sur Mer, Wimereux, Ambleteuse, Audreselles, Cap Gris Nez). On account of our findings on...

The correct binomial for Rumph’s “Folium tinctorum”
Provedor de dados: Naturalis Digital Academic Repository
Autores: Bremekamp, C.E.B.
In my “Notes on the Acanthaceae of Java” (in Verh. Kon. Ned. Akad. v. Wetensch., Afd. Natuurk. 2nd Sect. 45, 2: 29,1948) I discussed the three epithets that had been applied to Rumph’s “Folium tinctorum” after the latter had been transferred to the genus Peristrophe, which, as is well known, was based on this species. Nees, the author of the genus, has used the name P. tinctoria, because he regarded Justicia tinctoria Roxb. as the oldest binomial that had been applied to it. This was contested both by Merrill and by Hochreutiner. Merrill was of opinion that Justicia bivalvis L (1759) was its oldest name, but as I pointed out l.c. this binomial must be regarded as a “nomen confusum”; the description indicates a Dicliptera species, whereas the plate in the...

Stratigraphy and structural geology of the district west of the Marimana granite, Valle de Aran

In the summer of 1953 and 1954 a detailed 1:25.000 map was made of a part of the central Pyrenees. The mapping ranged from Salardu (Valle d’Aran) to Mongarri, (northeast of Salardu). Thanks to a grant from the Molengraaff fund a special study could be made of the structural geology of this district in the summer of 1954. In the course of this study, particular attention was given to the complicated folding tectonics and numerous “minor structures” were measured and examined. This method made it possible in some cases to locate synclines and anticlines without seeing their hinges so that some of the stratigraphy could be reconstructed. The stratigraphical sequence as a whole remains doubtful however, as all the layers in the district are nearly vertical and...

The preparation of a new account of the pteridophytes of the whole Malayan region is a very large undertaking, and when one is at the beginning of it, one cannot foresee what may happen during the course of its execution. It is in part a voyage of discovery. The work will have to be done in stages, and published in parts. To wait until it is all completed, and then to coordinate and re-arrange it before publication, would mean an unreasonably long delay. But to publish it in parts will inevitably mean that one will have new ideas about the early parts as one works on the later ones. My hope is that, when the work is finished, it will be possible to have a new and better conception of the inter-relations of the parts. Present schemes for definition of...

The concepts on which a morphology of the vascular plants should be based

Autores: Bremekamp, C.E.B.
It can hardly be denied that the expression “General Plant Morphology”, which is so often met with in botanical textbooks, has little or no meaning. A general morphology of the Plant Kingdom would have to occupy itself with those morphological features that are common to all groups of plants, which means that it would have to confine itself to the common features of the cell structure and eventually to such peculiarities as are independent of the uni- or pluricellular structure of the plant body, e.g. its enclosure within a rigid envelop. However, when we realize that there is in this respect no fundamental difference between the common features of plants and animals or, at least, of some groups of animals it will be clear that the use of the expression...

Competition Between Table Margarine and Butter
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lloyd,   Alan G.
In December, 1955, the New South Wales Government amended the Dairy Industry Act, 1915-1955, to increase the quota of margarine production in this State from 2,500 tons to 9,000 tons per annum. Following - on a large increase in the Queensland quota some years earlier, this development heightened the perennial fears of dairying industry organisations that competition from margarine would have very serious effects on the incomes of Australian dairymen. However, speaking during the second reading of the bill (November 23, 1955), the Minister for Agriculture and Food Production gave as his opinion that "whatever effect margarine has upon the dairy industry at present, the tendency in the future will be for it to diminish ... ". It is the purpose of this...

Extension Services and the Grazier on the South-West Slope
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Parish,   Ross M.
In this article information is presented regarding the extent to which graziers in a portion of the South West Slope have availed themselves of the extension services offered by the Department of Agriculture. Some analysis is also made of the characteristics of those who have had most, and of those who have had least, contact with the extension services. The material on which the article is based was collected, late in 1954 and early in 1955, from a random sample of IS0 graziers residing in the shires of Gundagai, Tumut, Tumbarumba, Holbrook and Kyeamba. A full description of the survey area and the sampling method, has already been published in this Review.'

Experimentos com os nematicidas D. D., E. D. B. e brometo de metilo no combate aos nematódeos causadores de galhas em raízes de plantas (Meloidogyne spp.)
Provedor de dados: Anais da Escola Superior de Agricultura Luiz de Queiroz

Tomato roots heavily disfigured by root-knot nematodes were throughly mixed with soil. At various time intervals, samples were taken from the mixture and treated in closed containers by each of the folio wing nematicides: D.D., E.D.B. and M.B. The efficacy of the treatment was tested by setting indicator plants in the treated soil and by examining their roots for the presence of galls two months later. In other words, the ability of the three nematicides to penetrate nematode galls after various periods of rotting, which varied from 5 to 30 days was studied. The main conclusions drawn are as follows: a) no nematicide among the three listed above showed the ability for complete destruction of the nematodes protected inside the roots, for a number of small...

Dois teoremas sôbre a função gama
Provedor de dados: Anais da Escola Superior de Agricultura Luiz de Queiroz
Autores: Gomes,Frederico Pimentel.
This paper proves the following theorems on the gamma function: Theorem I The integral ∫O∞ t u e-t dt = Γ ( u + 1 ) , where u, real or complex, is such that R (u) &amp;gt; -1, will not change its value if we substitute z = Q (cos φ + i sen φ) for the real variable t, being jconstant and such that - Π/2 &lt; φ &lt; Π/2 , Theorem II The integral ∫-∞∞ w2u + 1 e -w² dw = Γ ( u + 1 ) , where 2u + 1 is supposed to be a non negative even integer, will not change its value if we substitute z = w + fi, f being a real constant, for the real variable w. The proof of both theorems is obtained by means of the well known Cauchy theorem on contour integrals on the complex plane, as suggested by CRAMÉR (1, p. 126) and LEVY (3, p. 178).

Ocorrência de nematódeos do gênero Ditylenchus em tubérculos de batatinha no Est. de São Paulo
Provedor de dados: Anais da Escola Superior de Agricultura Luiz de Queiroz
Autores: Zamith,Adiel Paes Leme; Lordello,Luiz Gonzaga E.; Boock,O. J.
Irish potato tubers imported from Holland and Germany were planted at the Instituto Agronômico Experiment Station, Campinas, in April, 1955. At digging time, in July, 1955, the tubers were found to be injured by nematodes belonging to the genus Ditylenchus. No visible symptoms were found on the plants during the growing season, since the nematodes did not attack the stems. However, prevailing weather conditions from April to July were not favorable for nema activities, with low temperature and rain precipitation. Therefore, it does not seem safe to assume that, as a rule, the nemas do not attack buds and stems, for further observations may reveal such an occurrence, as it has been reported in the literature. The injury was characterized by spots consisting...

Nota preliminar sôbre a absorção e a translocação do radiozinco no cafeeiro [Coffea arabica] cultivado em solução nutritiva
Provedor de dados: Anais da Escola Superior de Agricultura Luiz de Queiroz
Autores: Arzolla,J. Dal Pozzo; Haag,H. P.; Malavolta,E.
Two water-culture experiments were carried out to study the absorption and the translocation of radiozinc in young coffee plants as influenced by two factors, namely, concentration of heavy metals (iron, manganese, copper and molybdenum) and method of application. Inert zinc was furnished at a uniform rate of 0.05 p.p.m.; the levels of iron supply were 0, 1.0 and 10 p.p.m.; manganese was supplied in three doses 0, 0.5, and 5 p.p.m.; copper - 0, 0.02, and 0.2 p.p.m.; molybdenum - 0, 0.01 and 0.1 p.p.m. When applied to the nutrient solution the activity of the radiozinc was 0.15 microcuries per plant. In the study of the leaf absorption, the radiozinc was supplied at the level of 0.10 microcuries per plant; in this case the material was brushed either on the...

Autores: Jardim,W. R.; Peixoto,A. M.; Silveira F°,S.; Gomes,F. Pimentel.
This paper deals with the estimation of milk production by means of weekly, biweekly, bimonthly observations and also by method known as 6-5-8, where one observation is taken at the 6th week of lactation, another at 5th month and a third one at the 8th month. The data studied were obtained from 72 lactations of the Holstein Friesian breed of the "Escola Superior de Agricultura "Luiz de Queiroz" (Piracicaba), S. Paulo, Brazil), being 6 calvings on each month of year and also 12 first calvings, 12 second calvings, and so on, up to the sixth. The authors criticize the use of "maximum error" to be found in papers dealing with this subject, and also the use of mean deviation. The former is completely supersed and unadvisable and latter, although equivalent, to...

The present work deals with the study of the effects of selfing and crossing in pures lines of okra inbred for five generations and the methods of breeding in this plant. This work is party of a large program of this Dept. to study heterosis in plants naturally self pollinated. The technic of selfing consists of tying with a string the floral bud before anthesis. To make controlled crosses, it is necessary to emasculate the flowers removing the anthers with small forceps, and to cover the flowers with a bag and wait for 1 or 2 days until the blooming. Also, the male parents are covered with paper bags prior to flowering. Finally, the pollen is brushed lightly over the stigma of the emasculated flowers and the females unit rebagged. The authors have tried...

Autores: Leme,Hugo de Almeida.
A aradura é a principal das operações agrícolas para o desenvolvimento das diversas culturas. A sua importância é conhecida desde as mais remotas eras. Assim, os romanos já tinham sua teoria sobre aradura. Desta forma o arado, a mais antiga das máquinas agrícolas, foi sempre motivo de atenção dos agricultores, fabricantes e técnicos em mecânica agrícola. A sua evolução foi bastante grande. O estudo do arado sob o ponto de vista agrícola e econômico, para exata aplicação da máquina, nas diversas condições de solo, é de máximo interêsse para a mecânica agrícola. Assim sendo, para orientar a correta aplicação do arado, o que constitui a presente tese, foi experimentado num solo arenoso, de características mecânicas (areia total 75,7%, argila 13,5 e lôdo...

A estimação do efeito residual de fertilizantes por meio da Lei de Mitscherlich
Provedor de dados: Anais da Escola Superior de Agricultura Luiz de Queiroz
Autores: Gomes,Frederico Pimentel.
This paper deals with the estimation of the residual effect of fertilizers through the use of Mitscherlich's law. The formulas and reasonings now presented are a further development of those introduced previously by PIMENTEL GOMES (2). The new formulas allow the estimation of the residual effect h in cases where the experiments are carried out in the same plots for two or three subsequent years (or crops). In an experiment analysed as an example, the residual effect of calcium hydroxide was estimated to be h = 0.423, that is, about 42%, so that one should advise the use of frequent application of small amounts of lime instead of heavy quantities used at long intervals.

As espécies Brasileiras do gênero Axonopus (Gramineae)
Provedor de dados: Bragantia
Autores: Dedecca,D. M.
O gênero Axonopus faz-se merecedor de estudos intensivos por duas razões: primeiramente, pelo importante papel que pode desempenhar na agronomia, dado o grande valor forrageiro de muitas das suas espécies e, em segundo lugar, pelo fato de apresentar, até os dias atuais, uma taxonomía extremamente confusa. Na verdade, devido às várias interpretações e conceitos que diversos autores lhe emprestaram, o gênero Axonopus, reunindo espécies de afinidades discutidas apresenta-se taxonómicamente mal definido, fazendo-se necessários urgentes estudos, não só morfológicos, como também anatômicos e citológicos das suas diversas espécies, visando ao esclarecimentos das suas afinidades. No presente trabalho são estudadas detalhadamente, do ponto de vista morfológico, 38...

Influência da matéria orgânica na capacidade de troca de cations do solo
Provedor de dados: Bragantia
Autores: Verdade,F. da Costa.
Os solos do Estado de São Paulo possuem, predominantemente, argilas do tipo caolinita, de baixa capacidade de cations permutáveis, o que leva a atribuir à matéria orgânica uma grande parte da capacidade de troca de catíons dêsses solos. Para avaliar a capacidade de troca de cations da fração orgânica, é esta destruida pela H2O2 a 12%, dosando-se, pelo processo de acetato de amónio, a C.T.C, no solo original e no solo tratado. Dos trabalhos efetuados, verificou-se que nos solos argilosos as primeiras frações da matéria orgânica destruidas possuem pequena capacidade de troca de catíons, enquanto as mais resistentes têm essa propriedade em maior escala. Nos solos arenosos, todas as frações orgânicas parecem apresentar a capacidade de troca com a mesma...

Autores: Viégas,G. P.; Freire,E. S.
No presente estudo são apresentados os resultados obtidos em dez ensaios - três dos quais repetidos, nos mesmos canteiros, por cinco, sete ou oito anos - visando investigar o efeito da torta de algodão empregada isoladamente ou em combinação com cinzas de café e farinha de ossos. Êsses ensaios foram realizados entre 1943-44 e 1951-52 e localizados em sete diferentes estações experimentais do Estado de São Paulo : Campinas, Capão Bonito, Jaú, Pindamonhangaba, Ribeirão Prêto, Santa Rita do Passa-Quatro e Sorocaba. Enquanto a farinha de ossos só aumentou significativamente a produção em Santa Rita, e as cinzas de café, em Santa Rita e Ribeirão Prêto, a torta de algodão provocou aumentos significativos em Santa Rita (dois ensaios), Ribeirão Prêto, Jaú e...

Perdas de elementos nutritivos pela erosão: I - Nitrogênio e suas relações com as quantidades existentes no solo e na água de chuva
Provedor de dados: Bragantia
Autores: Verdade,F. da Costa; Grohmann,F.; Marques,J. Quintiliano A.
Para estudar as perdas do elemento nitrogênio, ocasionadas pela erosão num solo tipo terra roxa misturada, em Campinas, utilizaram-se quatro talhões sujeitos a plantio e práticas culturais diferentes, mantidos pela Seção de Conservação do Solo, do Instituto Agronômico. As amostras da água de enxurrada e do material sólido arrastado de cada talhão eram retiradas de coletores especiais e as águas das chuvas que produziram enxurradas, dum pluviômetro mantido nesse campo experimental. Os resultados indicam que o nitrogênio nas formas nítrica e amoniacal, trazido pelas chuvas, só em parte 6 perdido pela erosão. Os ganhos em nitrogênio, pelo solo, compensam parcialmente as perdas dêsse elemento sob outras formas, ocasionadas pela água de enxurrada. Dependendo da...

Autores: Boock,O. J.; Catani,R. A.
Procurando estudar a influência da aplicação parcelada de nitrogênio e potássio, sôbre o desenvolvimento e produção de tubérculos de batatinha, foi organizado um plano preliminar com a duração de três anos, executado em Campinas, em solo pertencente ao grande tipo Glacial. Nêsse plano foram subdivididas as doses de nitrogênio e potássio, provenientes respectivamente do salitre do Chile e cloreto, de maneira a têrmos a aplicação de uma só vez (no ato do plantio), em duas, três e quatro vezes. Os resultados obtidos vieram demonstrar que houve um pequeno aumento de produção quando se subdividiu o nitrogênio três ou quatro vêzes, aumento êsse mais substancial no ano em que foi mais acentuada a queda pluviométrica durante o período de cultivo da batatinha....

Nematóides que parasitam a soja na região de Bauru
Provedor de dados: Bragantia
Autores: Lordello,Luiz Gonzaga E.
Entre os sérios fatôres que atuam contra a expansão da cultura da soja no Estado de São Paulo, acha-se o representado por nematóides parasitos. Dêstes, os que mais têm atraído a atenção dos cultivadores e fitopatologistas são as espécies formadoras de galhas no sistema radicular (Meloidogyne spp.). O estudo do material atacado coligido em Bauru revelou que, naquela região, três formas se acham envolvidas, a saber : Pratylenchus sp., Meloidogyne incognita (Kofoid &amp;amp; White, 1919) Chitwood, 1949 e M. javanica bauruensis n. subsp. Neste trabalho é estudada a nova subespécie, sendo também apresentadas algumas observações sobre a população de M. incognita.

Frutificação no cafeeiro
Provedor de dados: Bragantia
Autores: Reis,A. Junqueira; Arruda,Hermano Vaz de.
Realizaram-se contagens de frutos novos de café logo após o florescimento, em novembro, e de frutos completamente desenvolvidos, em fevereiro do ano seguinte, a fim de calcular as porcentagens de "pegamento" dos frutos, em alguns canteiros de um. ensaio de adubação, que haviam recebido combinações de adubo mineral e orgânico. As determinações foram feitas para as posições alta, média e inferior de cada planta, e o resultado médio foi correlacionado com os elementos usados na adubação e também com a produção das plantas. Os resultados obtidos indicaram que o fósforo, combinado com o estêrco, contribuiu para aumentar 3,5% à porcentagem de pegamento em relação à adubação sòmente com estêrco, e que o potássio também contribuiu com um aumento de 8,1% em relação...

Estudo do sistema radicular do algodoeiro nos três principais tipos de solo do estado de São Paulo
Provedor de dados: Bragantia
Autores: Cavaleri,Popílio A.; Inforzato,Romeu.
O presente trabalho refere-se ao estudo do sistema radicular de duas variedades de algodoeiro, em três tipos de solo do Estado de São Paulo. Os dados demonstram que para as variedades consideradas e nos tipos de solos pesquisados, o sistema radicular do algodoeiro alcançou profundidades apreciáveis. Dentre as variedades em questão, a LA. 7387-24940 foi a que apresentou sistema radicular mais profundo e mais abundante. Considerando o tipo de solo, a maior profundidade foi atingida na terra-roxa-misturada, seguindo-se em ordem decrescente a massapê e o arenito de Bauru. Independentemente da variedade e do tipo de solo, 80% em pêso do total de raízes situaram-se nos primeiros 20 cm da superfície do solo. Com base nêste fato é lembrada a importância de tratos...

Novos ensaios sôbre a seca das sementes de café ao sol
Provedor de dados: Bragantia
Autores: Bacchi,Oswaldo.
Compreendendo diversos ensaios realizados à sombra, ao sol e por meio de agentes químicos, o presente trabalho foi executado com o objetivo de eliminar dúvidas que existiam na literatura, especialmente quanto à possibilidade de se efetuar a seca da semente de café exclusivamente ao sol. Tendo em vista a confirmação integral dos resultados anteriormente publicados pelo A., pode-se afirmar que o processo de seca a pleno sol é perfeitamente viável para essa semente, desde que o seu teor de umidade não decresça, durante a seca, abaixo de 8-9%. Abaixo dêste ponto crítico a semente perde ràpidamente seu poder germinativo, mesmo quando desidratada por meio de agentes químicos, à temperatura ambiente.
