Sur un genre nouveau de monogenoidea parasite de la dorade chrysophrys aurata L.
Provedor de dados: 5
Autores: Euzet, Louis; Audouin, Jacques.
We believe that this parasite, despite the presence of just one squamodisc, belongs to family Dactylogyridae, subfamily Diplectanidae. This subfamily is defined as follows: Dactylogyridae possessing haptor with 14 marginal hooks and two pairs of large J-shaped anchors joined by two, three or five transverse bars. Sclerotised accessory organs (squamodiscs) on the body anterior to the haptor. Testis. Vagina observed. This subfamily currently comprises eight genera that all have two squamodiscs, one dorsal and one ventral, anterior to the haptor....

Remarques sur les rides sous-marines : théorie de la formation des rides
Provedor de dados: 5
Autores: Berthois, Léopold.
Numerous laboratory studies have been done on the formation and on the evolution of sand ridges. Durand (1951) studied the formation of ridges in channels. He showed that when a sand grain from the transport layer in direct contact with the bottom comes to rest, it has a tendency to stop all the other particles coming from upstream at the same level. The upper layers are slowed in succession and it is as if an additional layer had been added, with this layer being made up of particles taken from the permanent sediment discharge of higher regions in saltation....

Observations sur la croissance des huîtres plates dans les claires de la Seudre

Autores: Trochon, P.
La croissance de l'huître plate Ostrea edulis LINNE a été étudiée chaque année, de 1947 à 1959, dans les claires de la vallée de la Seudre. Le dépouillement de certaines observations recueillies au cours de ces 12 ans a permis de déterminer la croissance moyenne des huîtres plates en fonction de leur poids au moment de la mise à l'eau en claire et de mettre en évidence l'influence de conditions météorologiques et hydrologiques sur cette croissance.

La pêche à la sardine ne représente qu'une faible part de la pêche française; elle est cependant d'une grande importance sur le plan économique et social.

D'autre part. on ne doit pas oublier qu'elle approvisionne les usines de conserves du littoral lesquelles emploient une main-d'oeuvre nombreuse essentiellement recrutée dans le milieu des pêcheurs,   La pêche à la sardine, comme beaucoup d'autres activités artisanales est très irrégulière en...

Deuxième contribution a l'étude de la sédimentation dans le golfe de Gascogne
Provedor de dados: 5
Autores: Berthois, Leopold; Le Calvez, Yolande.
Après avoir exposé en détail les caractères des sédiments dragués et carottés, nous allons résumer les données acquises puis nous tenterons d'en faire la synthèse dans les conclusions.   Les faits suivants ont été établis:   1° Les dragages sur les pentes du talus du plateau continental ont fourni des galets dont la lithologie est très monotone. Les principaux composants sont le quartz, les quartzites et plus rarement les roches cristallophylliennes. Les roches éruptives sont toujours très rares ou sont totalement absentes dans plusieurs stations.   Les dragages des stations 343 et 369 ont fourni des graviers en nombre important (quartz et quartzites).  Il est à noter que les terrasses de la Garonne présentent la même monotomie lithologique (HAUG, 1920)....

Le microdosage du formol dans les produits marins
Provedor de dados: 5
Autores: Soudan, France.
Leur concentration exprimée en formol est habituellement de 200 à 1 000 mg par kg de produits aseptisés, 10 à 45 mg par kg de produits fumés [HENDERSON (12). SHEWAN (21)]. 4à 500 mg par kg de poisson salé [REAY (17)]. Les intervalles de variation sont donc trop rapprochés pour être distingués autrement que par un dosage: une réaction qualitative suffisamment sensible pour déceler sûrement, dans une prise d'essai de quelques grammes, une dose de formol inférieure au milligramme sera probablement positive avec une quantité cinq fois moindre valeurs qui correspondent respectivement à une adjonction ou à une présence normale. La distinction revêt une certaine importance dans les pays comme la France où l'addition de tout antiseptique aux matières alimentaires...

Première campagne 1959 du navire "Président Théodore Tissier" - Prospection des accores, du sud-est de la Grande Sole au Cap Finistère
Provedor de dados: 5
Autores: Letaconnoux, Robert.
Du 6 janvier au 28 février, le "Président Théodore-Tissier" a effectué sa première campagne de 1959, consacrée à l'étude du bord du plateau continental, du Sud-Est du banc de la Grande Sole au Cap Finisterre.  La réalisation de ce programme a été faite avec le souci d'effectuer un relevé aussi précis que possible de la topographie de la zone des accores entre les profondeurs de 200 et 800m. Après un dépouillement succinct des sondes, des traicts de chalut ont été tentés chaque fois que possible entre 400 et 800m afin d'étudier la distribution des espèces commerciales parmi la faune profonde.  Le chalut utilisé, de type cailloux, était en manille (25 m de corde de dos, 35 m de bourrelet, mailles de 45 mm). Tous les traicts effectués ont été de 2 heures et...

These observations were recorded on biological samples from the Atlantic coast of Morocco between 1947 and 1950. This study continues the work by M.-L.

We have already given all the details on the sampled area, capture conditions and the hydrological situation. The most important hydrological features are the rise of the waters from the continental margin along the coast in spring and summer and the partial invasion of offshore waters in the coastal zone during the same seasons....

Les bancs naturels et la reproduction de l'huître plate en Morbihan
Provedor de dados: 5
Autores: Marteil, Louis.
Natural beds of Ostrea edulis, long since decimated, began to repopulate the rivers of the Morbihan "département" in 1943. In 1955, I reported results acquired during the 1943-1954 period and highlighted the effects the repopulation seemed to have on oyster spat collection. It is thus useful to explore to what extent the population has grown and the influence that the renewed population success has had on the European flat oyster in bays and rivers.

L'utilisation d'un pont de wheatstone électronique enregistreur pour la mesure des températures des nappes d'eau (note préliminaire)

Autores: Audouin, Jacques.
Depuis l'invention en 1878 par NEGRETTI et ZAMBRA du thermomètre à renversement, universellement employé aujourd'hui par les océanographes, plusieurs tentatives ont été faites pour mettre au point des appareils destinés à la mesure électrique des températures de l'eau de mer à diverses profondeurs. Citons l'appareil de SIEMENS basé sur la variation de résistance électrique d'un fil avec la température, le sondeur thermo-électrique de LABOUREUR, le thermomètre enregistreur de REGNARD et enfin les thermomètres imaginés par IDRAC. L'un de ceux conçus par IDRAC était basé comme celui de SIEMENS sur l'emploi d'un pont de Wheatstone accouplé à une résistance variant avec la température.

Autores: Lubey, Pierre.
Our knowledge on spawning and ejaculation in bivalve molluscs is based mainly, if not wholly, on research carried out on Gryphaea (Crassostrea) virginica by Galtsoff (1938-1941) and Nelson (1940-1948). Gamete release can be triggered by a sudden increase in temperature (Galtsoff). Gamete release may also be triggered by substances, emitted by gametes of the opposite sex, which selectively stimulate sexually mature animals ("Galtsoff hormone")....

Autores: Ancellin, Jacques; Nedelec, Claude.
A tagging survey of herring took place in November 1957 in the southern part of the North Sea and in the eastern English Channel on board the research vessel the "Président-Théodore-Tissier". This survey aimed to contribute to international research efforts to determine if herring stocks are over-exploited. In all, 11 648 herrings were tagged, using French- and foreign-designed tags, in the Sandettié area off Cape Blanc-Nez, on the Vergoyer shoals and at Cape Ailly. Three hundred and sixty seven recaptures (3.15%) were recorded during the 14 month period following tagging....

La pêche au chalut en Mauritanie

Autores: Letaconnoux, Robert.
Si la route de Mauritanie est actuellement bien connue des langoustiers, les chalutiers, par contre, ont complètement abandonné ces lieux de pêche depuis la fin de la seconde guerre mondiale.  Dès 1905, ce sont des chalutiers de Boulogne et d'Arcachon qui allèrent les premiers en Mauritanie, rapportant à chaque voyage de 100 à 120 tonnes de poisson. Après la première guerre mondiale, les rochelais y remplacèrent les boulonnais puis, de 1940 à 1945, la pêche ne fut plus pratiquée que par les chalutiers de Casablanca et par la flotte des navires repliés sur Marseille. Depuis, en dépit de quelques tentatives sans lendemain effectuées jusqu'en 1950, les chalutiers français ont complètement abandonné la Mauritanie au profit des italiens, et surtout des...

Hydrologie du Maroc atlantique
Provedor de dados: 5
Autores: Furnestin, Jean.
Many oceanographers acknowledge the particular features of the waters from the continental shelf-also called continental waters, but which should be called coastal waters. Less saline than offshore waters, coastal waters are often warmer in the summer and colder in the winter, at least in temperate regions. Given their shallowness and their proximity to the coast, coastal waters are subject to currents and mixing that are highly influenced by tides, waves, floods and various atmospheric factors. These features make for a mixed area where classic hydrological features are obscured by local and seasonal variation and not expressed as clearly as in offshore waters. This may be one of the reasons why oceanographers have concentrated their efforts on offshore...

Observations complémentaires sur la nature du cycle sexuel de Gryphaea angulata Lmk dans le bassin d'Arcachon
Provedor de dados: 5
Autores: Le Dantec, Jean.
Les premiers résultats de nos recherches ont été exposés dans une communication au Conseil International pour l'Exploration de la Mer en 1957. Ils pouvaient être ainsi résumés : Le cycle sexuel semble être moins long pour les huîtres cultivées sur parcs que pour celles fixées naturellement sur pieux. Un même animal est vraisemblablement capable de pondre au moins deux fois pendant les mois d'été. Le volume de gonade diminue progressivement, ce qui rend malaisée la distinction des stades macroscopiques permettant une étude statistique. La taille des ovocytes diminue également pendant la saison; un nouveau matériel apparaît puis évolué (phénomènes de reconstitution permettant de prévoir des émissions tardives).

Les pêcheurs français attirent la sardine à l'aide de rogue mélangée à de la farine d'arachide. Or, depuis quelques années, les oeufs de morue sont utilisés dans l'alimentation humaine, ce qui a fait monter les prix et réduit le contingent affecté à la pêche, d'où les difficultés de plus en plus grandes qu'éprouvent les coopératives pour approvisionner les sardiniers. D'autre part le tonnage de rogue utilisé chaque année augmente sensiblement les frais des équipages et la dépense est d'autant plus forte que la pêche est faible.

Hypericum canadense in Europe

In 1935 the present author reported the occurrence of this N. American species in the eastern part of Holland, province of Overijssel, in the vicinity of Almelo (JONKER, 1935). He found the species near the hamlet of Harbrinkhoek on a wet heath. The locality was also the only station of Wahlenbergia hederacea in the Netherlands, discovered a year before. Notwithstanding the extensive reclamations in that part of the country the species now still occurs in a number of localities around Almelo. The plants cannot be considered adventitious as they were found in places that are comparatively little influenced by human culture, judging from the occurrence, on the first-discovered locality, of e.g. Wahlenbergia hederacea.

Since the publication of my revision of the Vespinae of the Indo-Malayan and Papuan areas (1957), I have had the opportunity to study a considerable amount of additional material of this subfamily. Part of this material originated from the areas treated in my previous paper, and in so far as the following notes refer to these specimens, they may be regarded as a first supplement to that revision. The present paper, however, also contains some information on the Vespinae occurring in India, China, and Japan. At first I had hoped to round off my studies of the Vespinae by preparing a more or less complete revision of the Vespa species of the Asiatic continent, but so far it has proved impossible to accumulate sufficient material for this purpose.

Provedor de dados: 16
Autores: Wiebes, J.T.
INTRODUCTION In this paper the species of spiders belonging to the families Lycosidae and Pisauridae, known from the Netherlands, are described and figured. In addition a number of species, which possibly may occur in the Netherlands though they have not yet been found here hitherto, are mentioned in the keys. In order to make the keys useful also for identifying immature specimens, I have based these keys not only on the well-known differential characters in the adult sexual organs, but also, as far as possible, on characters derived from colour-pattern and chaetotaxy. The system of notation, used to indicate the situation of the spines on palps and legs, is briefly stated as follows (Wiebes, 1956, pp. 408, 409) : d, 1', 1", v', and v" indicate dorsal,...

The differentiation within the genus Chamaeleo Laurenti, 1768
Provedor de dados: 16
Autores: Hillenius, D.
The main purpose of this study is to search for an explanation of the curious differentiation within the genus Chamaeleo. Since the species of this genus are rather doubtful units, I have studied the geograpical distribution of characters, not of the species, a method first used in botany (BAUR, ROTHMALER a.o.). I found that the number of characters is largest in east Afrika, gradually decreasing from this area to the periphery of the total range of the genus. East Africa proved to be still more important, as practically all the characters occur in it. This means that the chameleons in the other areas practically never possess characters that are not found in east Africa. This pattern of distribution fits in rather well with REINIG’S elimination theory...

The work of preparation of a new survey of all the Pteridophytes of Malaysia will occupy a considerable period. It is proposed to publish this work in parts, as studies of particular families or genera are completed, but it is impossible to plan in advance the precise sequence of these studies. It is anticipated that the new information to be recorded, and new ideas based upon it, will throw a good deal of new light on the delimitation of genera, and upon the inter-relationships of genera, especially among the ferns, which are by far the largest of the major groups concerned. Therefore one cannot now predict what final scheme of classification will emerge. But it is necessary to have some sort of conspectus at the start, as a preliminary survey of the...

Outbreaks of the Tentcaterpillar (Malacosoma neustria L.) on elm trees in Amsterdam and the efforts to control them with derris-powder
Provedor de dados: 16
Autores: Kalshoven, L.G.E.
A review is given of the recurrent outbreaks of the tentcaterpillar, Malacosoma neustria L., affecting the elm trees in the city of Amsterdam in the period 1930—1957. An outbreak of the brown tail moth, Euproctis chrysorrhoea L., in 1935—1936 is also mentioned and some occasional loss of foliage through the caterpillars of the vapourer moth, Orgyia antiqua L. Large fluctuations in the size of the Malacosoma populations were found. After some years in which the damage was negligeable, the increase always started in the N.W. part of the centre of the city. In the following years the outbreaks moved to adjacent parts of the centre and finally sometimes even to more eccentric parts (see Fig. 6—9). However, the occurrence of really harmful numbers of...

The genus Rhizophora in Suriname
Provedor de dados: 16
Autores: Jonker, F.P.
The peculiar distribution of the species of Rhizophora (Rhizophoraceae) is wellknown. Floras and manuals usually mention one western species — R. mangle L. — that occurs both in the coastal regions of tropical and subtropical America and in the corresponding habitats of west tropical Africa, and an eastern species — R. mucronata Lam. — occurring both in tropical Asia and in east tropical Africa. It is also well-known that a few other species occur in tropical Asia; a recent revision has been given by HOU (1958). G. F. W. MEYER (1818) described from British Guiana a second American species, R. racemosa, differing in the inflorescence which is forked and 2-flowered in R. mangle and much-branched in R. racemosa.

The results of an investigation of the structure and sedimentology of Upper Westphalian and Lower Stephanian strata in the eastern end of the Cantabrian palaeozoic core (NW Spain), are presented. The sediments, shales, sandstones, limestones and coal seams occur in three main associations: the orthoquartzite-carbonate, the turbidite and paralic associations. Two facies are dstinguished: a western, without turbidites, with relatively many coal seams and an eastern, with turbidites and a few coal seams. Some evidence for a zone of less subsidence is present. This zone separates the two facies. The western and eastern facies are represented by the rocks in the Sierra Corisa and Redondo synclines respectively. Between the two synclines occurs a zone of long...

Een nieuwe vindplaats van Carex reichenbachii Ed. Bonn
Provedor de dados: 16
Autores: Voo, E.E. van der.
Op 16 mei vond ik in de gemeente Wilnis op de westhelling van de Westveense kade van de Kromme Mijdrecht een vrij dichte vegetatie van Carex reichenbachii. Volgens de auteurs van de Flora Neerlandica (I, 3, 1954) „is de plant zeker vaak over het hoofd gezien.” Dit is wel aannemelijk, omdat de habitus doet denken aan Carex ligerica of aan een nog niet volgroeide C. brizoides op overeenkomstige standplaatsen. Maar in het onderhavige geval, waarbij een soort van de sectie Arenariae (behalve dan C. disticha) op een kade in het Hafdistrict werd aangetroffen, voelde ik mij door deze merkwaardige groeiplaats wel gedwongen, de plant wat nauwkeuriger te onderzoeken. Onmiddellijk vielen daarbij de gekromde aartjes op, De determinatie gaf, hoewel de urntjes nog niet...

Autores: Womersley, H.
SYNOPSIS The type slide of the species Fedrizzia helleri briefly described by Oudemans 1929 from Paramaribo, Dutch Guiana, but never figured, has been re-examined. The species is now shown to belong not to the genus Fedrizzia Canest. (fam. Fedrizziidae) but to the genus Klinckowstroemiella Turk 1951 (fam. Klinckowstroemiidae). The species Fedrizzia helleri was briefly described by Oudemans 1929 as follows: "Fedrizzia helleri nov. sp. Er is geen scherp begrensd sikkelvormig scutum verticale; wel is dit gedeelte naar den voorrand membraneus; die voorrand is niet zuiver rond, maar iets golvend; er zijn 4 stralende vertikaalhaartjes op geplaatst, die op gelijke afstanden van elkander staan. Verder is de rug haarloos. ♀ genitaalopening trapezoidaal, vóór bijna...

On the systematic position of the Western Hamster, Cricetus cricetus canescens Nehring (Mammalia: Rodentia)
Provedor de dados: 16
Autores: Husson, A.M.
The systematic position of the western hamster, Cricetus cricetus canescens, has been a subject of discussion and criticism ever since NEHRING (1899, pp. 1—2) described the hamster occurring in Belgium west of the Meuse as a separate variety. The present paper is a new effort to throw more light on the interesting question concerning the systematic characters by which the western hamster can be distinguished from the typical form described from central Germany. For a better understanding of the present study a brief survey of the main points in the historical development of this problem follows here. According to NEHRING the main characters in which his new variety, Cricetus vulgaris var. canescens, differed from the typical form, were: (1) the dark...

Revision of the Burseraceae of the Malaysian area in a wider sense. Xa. Canarium Stickm
Provedor de dados: 16
Autores: Leenhouts, P.W.
The scope of the present paper is primarily to give a taxonomical revision of the genus Canarium. Furthermore, attention has been paid to some subjects of a more general nature, mainly regarding morphology and geography, without, however, claiming completeness. The last complete revision of the genus was published by Engler in 1883 (in DC. Mon. Phan. 4, 101—151). Of course this is now for the greater part out of date. The later revisions by the same author in E. &amp; P., Nat. Pfl. Fam. ed. 1, 34, 1896, 238—242, and ed. 2, 19a, 1931, 443—450, are not really monographs; moreover, they lost in value by the introduction of a subdivision which was mainly based upon unessential characters.

Geological Investigations on Boulder-Clay of E. Groningen
Provedor de dados: 16
Autores: Gijzel, P. van; Overweel, C.J.; Veenstra, H.J.
In this article the results of a study on boulder-clay in the neighbourhood of Winschoten (N.E. Netherlands) are communicated (Chapter I). The underlying sediments of the boulder-clay in this area consist of fine preglacial sands and black clay. In the nuclei of the many drumlins a strongly ice-pushed boulder-clay may be encountered (Chapter II). Palynological analysis showed the pollen content of the boulder-clay to be very small. In a few samples more pollen was found (Plates I and II), but in these cases there appeared to be an admixture of black clay, obviously picked up by the land-ice. This black clay (the so-called potklei or pottery clay) is very humic and resembles the Lauenburg clay from Germany, but is younger. Using pollen analysis only one...

A study of Heterophylly and Inflorescence structure in Dendrophthora and Phoradendron (Loranthaceae)
Provedor de dados: 16
Autores: Kuijt, Job.
Heterophylly is frequent in Dendrophthora and Phoradendron, and may take many forms. The concepts prophyll, cataphyll, and scale-leaf are briefly discussed and defined as to usage in the Phoradendreae. Various morphological details of patterns of heterophylly, flower orientation and seriation, fusion of prophylls, phyllotaxy, sex distribution and inflorescence position are traced as far as the available material permits. A typology of inflorescences in these two genera is proposed, based on flower seriation. Anatomical observations on a few species of both genera have revealed striking and unsuspected structural differences between the inflorescences of some seemingly related species, but also similarities which cross the intergeneric boundary.

Notes on the Araceae of Suriname II
Provedor de dados: 16
Autores: Jonker-Verhoef, A.M.E.; Jonker, F.P.
After the publication of the Araceae in the Flora of Suriname 1.2 (1953), p. 1-80, a number of rare and new species have been collected. Some of these were collected by Dr. J. Lindeman between 1953 and 1955, the remaining by the present authors, who visited Suriname from November, 1955, to March, 1956. Field observations by the authors clearly indicated the fragmentary status of our knowledge of Suriname Aroids. The reasons for this are to be sought in the difficulties involved in collecting and preserving. Also, a number of species may not flower over a period of several years. The inflorescences of many lianas are often almost inaccessible. A source of confusion is the variability in the leaves of a species. The following is an enumeration of species...

Plochmopeltis intricata (Ellis &amp; Mart.) Theiss., the type species of the genus Plochmopeltis Theiss. occurs on the underside of leaves of Quercus virginiana var. virescens and Quercus laurifolia. The fungus grows superficially, with flattened ascomata which are not covered with a perithecial wall. The asci are surrounded by paraphysoids, which are brown and furcate into short branches at their apices. A new species, collected on leaves of Olea americana is described as Plochmopeltis ellisii v. Arx. The genus Plochmopeltis is related to Schizothyrium Desm. and Phillipsiella Cooke, and should be placed in the Dothiorales.

Wilcoxon’s two-sample test
Provedor de dados: 16
Autores: Bloemena, A.R.
It one has a group of samples from one population and a group of samples from another population, one is often faced with the question whether both populations are the same or not. For this situation several statistical tests are available, one of these being the well-known Student's test (cf. Dixon and Massey, 1951, chapter 9). One of the assumptions underlying Student's test is that the quantities, of which observations are available, have a normal distribution. In many cases, however, it is not known whether or not this assumption is satisfied. In these cases it is advisable to use a statistical test, not based on the assumption of normal distributions. In the problem concerned one can use, e.g., Wilcoxon's two-sample test. The assumptions underlying...

Field studies on the surface fauna of forests
Provedor de dados: 16
Autores: Drift, J. van der.
In most handbooks on forest entomology much stress is laid on the importance of predatory arthropods in the soil as enemies for pupating noxious insects (ESCHERICH, 1923; GRAHAM, 1939). However, detailed investigations in the field on the significance of these predators are scarce. In Germany much work has been done on the biology and feeding habits of Carabus species (KERN, 1921; LENGERKEN, 1921; OERTEL, 1924; DELKESKAMP, 1930; KIRCHENER, 1927; JUNG, 1940) but these observations and experiments were mainly done under laboratory conditions. FORBES (1880, 1882) investigated the gut contents of many carabid species and concluded that about 1/3—1/4 of the food was of animal origin. VITÉ (1953) studied the significance of spiders in forests.

Alnus as a disturbing factor in pollen diagrams
Provedor de dados: 16
Autores: Janssen, C.R.
It is commonly accepted that percentages of pollen in a pollen diagram do not express the exact composition of forests in earlier times. This inaccuracy is due to several factors, for instance the different quantities of pollen produced by plants, the distance of transport etc. A pollen diagram tells us only the change in pollen rain on the locality where we collected soil samples. In studying a pollen diagram we find a close relation between the variations in the percentages of a certain species and the area occupied by this species in the vegetation. When the percentage of pollen of a species increases, we conclude generally that the relative area occupied by this species in the vegetation increases too. However, such a connection might be doubted. The...

CARL FREDRICK ALBERT CHRISTENSEN (1872-1942) was the founder of modern fern taxonomy. To appreciate the scope of his work, it is necessary to understand the confusions of thought on the subject which persisted through the 19th century and were still evident in the summary prepared (by DIELS) for ENGLER &amp; PRANTL’S Pflanzenfamilien in 1899. CHRISTENSEN’S first great work was his Index Filicum (1905-6) in which he listed all known fern binomials and also relegated many to synonymy. In the main he adopted the classification and nomenclature of DIELS. While preparing the Index he came to realize that many generic concepts accepted in the Index were unnatural or confused. This was especially evident in the great complex of species which he listed under the...

Man, predatory animals and the balance of nature
Provedor de dados: 16
Autores: Curry-Lindahl, Kai.
The balance of nature is a phenomenon much written about, but of which few people seem to have a clear idea. There are four essential elements in the balance of nature: water, soil, flora and fauna. The latter group also includes man. Each of these components is of fundamental importance for the three others. The balance, as a whole, is immediately influenced by a change in any one of these groups. The factor which most often disturbs this state of equilibrium is man. His actions can be of a more destructive character than sudden natural catastrophes. The latter may, it is true, cause an immediate upheaval, but it is usually of relatively short duration, and a new state of equilibrium is comparatively quickly attained by nature, herself, based, perhaps, on...

Activity of the thyroid and the pituitary gland in the viviparous Cyprinodonts Lebistes reticulatus (Peters), Xiphophorus helleri Heckel and Xiphophorus maculatus Günther during the development of the gonopodium
Provedor de dados: 16
Autores: Stolk, A.
A description is given of the activity of the thyroid and of the pituitary gland during the development of the gonopodium in the viviparous Cyprinodonts Lebistes reticulatus (Peters), Xiphophorus helleri (Heckel) and Xiphophorus maculatus (Günther). During this process the thyroid gland and the glandular lobe (lobus anterior and lobus intermedius) show a gradual increase in activity. This activity was in general most pronounced in Lebistes reticulatus (Peters) and weakest in Xiphophorus maculatus (Günther). This increase in activity suggests that the developement of the gonopodium is probably regulated endocrinally. For the determination of the state of thyroid and pituitary activity use was made of the quotients d/n and D/n (Lever, 1948 and 1950; cf....

Lophopodella pectinatelliformis nov. spec. (Bryozoa-Phylactolaemata)
Provedor de dados: 16
Autores: Lacourt, A.W.
A new species of freshwater Bryozoa has been found at Patua, Sumatra by Dr. A. Holleman-Haye. It belongs to the genus Lophopodella which has an Aethiopean-Indian range. The genus Lophopodella is characterised by its large oval statoblast, large capsule and broad annulus. This annulus possesses one or more spines at the poles. These spines are studded with very small anchor-like hooklets. The genus Lophopodella is closely related to the genus Pectinatella. The statoblasts of the latter genus may bear large spines without hooklets or, on the other hand, a great number of small spines (or hooklets) which are directly placed on and around the entire margin, as e.g. in Pectinatella gelatinosa Oka. Characteristic of the new species of Lophopodella is that the...

Sediments in the foreland of a mountain chain are sometimes suited to reconstitute the conditions in these mountains at the time of deposition of the sediments. The present study gives the results of a sedimentological investigation of the Tertiary and Quaternary deposits in a part of the Duero basin, situated south of the Cordillera Cantabrica, which supplied the sediments. The aim was to determine both the conditions in the source area, and the environments in the area of deposition. The investigated area is situated in the province of Palencia, between the rivers Pisuerga and Carrión. The area being a part of the so-called Meseta, has a simple relief. Two levels at different heights can be distinguished. The higher level, páramo, is strikingly flat, the...

In the earliest papers on neotropical Blattidae a fair number of specimens from Surinam were recorded (LINNAEUS, DE GEER ¹), DE SAUSSURE, BRUNNER). But in the period from the beginning of this century up to now only a few scattered reports of Blattidae from that region have appeared in the literature of the subject. The present article will be the first to deal exclusively with Surinam species. The material dealt with in this paper was mainly secured by DR. D. C. GEIJSKES between 1938 and 1955. His extensive travels both in the coastal area and far into the interior of Surinam enabled him to collect all over the country.

Die Seepocke Elminius modestus Darwin, die sich während des Krieges in England ansiedelte (Bishop, 1947) und sich dort schnell verbreitete, ist ein interessantes Objekt um diese Annahme zu prüfen.

Some remarks on the birth of a Father David’s Deer, Elaphurus davidianus Milne Edw
Provedor de dados: 16
Autores: Doorn, C. van; Slijper, E.J.
At the Royal Zoological Gardens “Blijdorp” at Rotterdam May 6th 1958 a Father David’s Deer gave birth to a female calf. It was the first young of this three year old doe. During the days before the day of birth the doe was seen several times leaping upon the buck. Experience with other Ungulates has taught that such behaviour may be regarded as an indication that the time of delivery is approaching. On the day of birth the doe refused her food as has been observed in many other mammals. She lay down very often, gnashed her molar teeth and made movements with her head towards the belly and the udder, the ears flattened to the neck, as if she was suffering from cramps. One had the impression, however, that the expulsion of the young was kept back until the...

Wie ich schon in Parnassiana Nova XXVI zum Ausdruck gebracht habe, hat das jahrelange Studium des mir zugänglichen Parnassius-Materials und die Beobachtung von Parnassiern in der freien Natur neue Gedanken in mir aufkommen lassen, die in diesem ,,Nachtrag" festzuhalten, mir wünschenswert erscheint. Der behandelte Stoff erstreckte sich, wie aus den Titeln von Parnassiana Nova XXI-XXVI hervorgeht, nicht nur auf die ,,Kritische Revision des genus Parnassius F.", vielmehr auf die der gesamten subfamilia Parnassiinae F.

Rivulid Fishes of Suriname and other Guyanas, with a prelininary Review of the Genus Rivulus
Provedor de dados: 16
Autores: Hoedeman, J.J.
The present paper embodies the results of a study of 362 specimens of the genus Rivulus from Suriname and the other Guyanas. So far, 58 species names (morphological species or subspecies) have been proposed, by a great many authors; these names are listed on pages 52—53. Of the 58, topotypical specimens have been examined in 8 instances. In order to facilitate a future review of the genus, which is in great need of revision, short remarks are made on the morphology and ecology of a number of specimens, from various localities, belonging to distinct species.

Heaths and Inland Dunes of the Veluwe. A study on some of the relations existing between vegetation, soil and microclimate
Provedor de dados: 16
Autores: Stoutjesdijk, Ph.
The Veluwe is a stretch of high ground in the central part of the Netherlands, north of the river Rhine and south of the IJssel Meer, i.e. the former Zuiderzee, and the polders reclaimed from the latter. Geologically the area consists of three formations: 1. ridges which owe their origin to the pressure of the land ise, and which consist of sands deposited as river sediments in preglacial times; 2. a fluvioglacial formation; on some of these plains small but steep hills are found; 3. aeolian sediments: löss and cover-sands (cf. VINK, 1949); they were deposited in the late-glacial period.

Mijn eerste aantekeningen over Solanum triflorum, die hier plaatselijk veelvuldig groeide, dateren van september 1952. Na 1955 was ik hier echter niet meer geweest en toen ik op 26 juli 1959 met A.

Stomatopod Crustacea of Suriname

The present report is based in the first place on material collected by the trawler “Coquette”, which, from April to August 1957, explored the offshore waters of Suriname and French Guiana from the mouth of the Nickerie River in the west to the Iles de Salut in the east. Most of the hauls were made at a distance of 20 to 30 miles from the coast. The paper also considers the Stomatopoda collected off the Suriname coast by the Suriname Fisheries Service. To date, only one species of stomatopod has been reported from Suriname, viz. “Gonodactylus chiragra Fabr.”, so named by NEUMANN (1878, p. 39), who reported on a specimen which is preserved in the collection of the Heidelberg Museum and was said to have originated from Suriname.

Er bestaat op het ogenblik de neiging de kleine waterweegbree Baldellia ranunculoides (L.) Parl. te noemen in plaats van Echinodorus ranunculoides (L.) Engelm. In de nieuwste druk van de flora van Heukels-van Ooststroom werd deze naam in de Nederlandse literatuur geïntroduceerd. In mijn Alismataoeae-bewerking voor de Flora Malesiana (1957) heb ik de naam reeds afgewezen, doch een nadere argumentatie zal de Nederlandse floristen stellig interesseren. In 1854 heeft Parlatore Schinodorus ranunculoides als het type van een nieuw monotypisch genus Baldellia aangevoerd, doch hij werd niet nagevolgd. Volgens Pichon (1946) is er evenwel alle reden voor om dit wel te doen, want hij meende niet minder dan 4 kenmerken gevonden te hebben, waarin E. ranunculoides van...

Since the last Bulletin was published our circle of collaborators has unfortunately lost Dr A.H.G. Alston, who had agreed to join Prof. Holttum in editorship of the Fern volumes of the Flora. It is an irreparable loss to pteridology as Dr Alston had an unparalleled, detailed knowledge and has unfortunately postponed the publication of a large amount of his findings and conclusions, which are now lost or doomed to remain unavailable in hardly legible written and uncorrected notes. I hope that it will be found possible to edit his interpretation of the Hortus Malabaricus of which he possessed a card index which obviously dated from his Ceylon time.

The fossil remains of rodents described in the present paper are from various localities. The large extinct musk rat Megalomys occurs in reddish-brown phosphatic “oolite” fillings of irregular cavities in a marine limestone found by Mr. P. H. DE BUISONJÉ in the north-western part of the Duivelsklip, eastern Curaçao, about 50 m above sea-level. The “oolite” also contains scanty remains of lizards, snakes, and of a bat. Fragmentary molluscs present possibly include Cerion uva (L.), a recent, very common, terrestrial species, as well as other gastropods, many opercula of which were found. Samples of a phosphatic “oölite” deposit collected in 1937 by Dr. P. WAGENAAR HUMMELINCK from an escarpment near Fontein, Bonaire, proved to contain jaws, with teeth, of a...

It represents the third facsimile edition of the work and, in spite of the earlier Berlin (1907) and Tokyo (1934) editions, which are no longer obtainable, it will certainly fill a real need, were it only to save copies of the rare and expensive original from wear and tear. Although much has been written about Linnaeus and his numerous publications, the delightful frame provided by W. T. Stearn and J. L.

Microscopically, the tumour, which originated from the subcutaneous connective tissue, was composed of areas of adipose tissue and areas of fibrous connective tissue. The tumour belongs to the fibrolipomatous type and shows a striking resemblance with the lipoma, described by Stolk (in press) in the lizard Lacerta muralis.

Provedor de dados: 16
Autores: Nannenga-Bremekamp, N.E.
On account of the reticulate spores with their large area of dehiscence and because of the structure of the pseudo-capillitium the monotypic genus Liceopsis and Enteridium splendens (syn. E. rozeanum) are returned to Reticularia. It is argued that R.? rozeana can not with certainty be identified, but that it can not be regarded as conspecific either with R. lobata or with R. splendens. Of R. lycoperdon a var. americana is separated, differing from the type by its free spores. A new species, R. intermedia, is described. It resembles R. lycoperdon in the dendroid pseudo-capillitium, but differs from the latter in the fragile cortex and in the filamentous structure of the pseudo-capillitium. It is known so far only from the vicinity of Doorwerth, province of...

On Eumenes Arcuatus (Fabricius) and some Allied Indo-australian wasps (Hymenoptera, Vespidae)
Provedor de dados: 16
Autores: Vecht, J. van der.
In a study on the variation of Polistes and other Vespidae, K. Zimmermann (Zeitschr. Morph. Oek. Tiere, 22, 1931, pp. 173-230) concluded that the variation of the Indo-Australian Eumenes arcuatus (Fabricius) differs in a remarkable way from that of several European species of wasps. The geographic variation of the palaearctic Polistes, Odynerus and Eumenes was found to be strongly influenced by external factors: black pigments increase in cold and humid environments, whereas the yellow pigments dominate in hot and dry areas. According to Zimmermann, there is considerable individual variation in this respect in the palaearctic region, and no constant geographic races have developed here. On the other hand, the Indo-Australian Eumenes arcuatus occurs in a...

Lichenology in Great Britain nowadays rejoices in increased activity and interest. This is evidenced by the foundation of the British Lichen Society which came into being some time ago, and now runs its own journal, The Lichenologist. The present book is another example, and it certainly appears at an appropriate time. The book which is written in clear and simple language contains a few introductory chapters (on the structure of lichens, the use of reagents and apparatus, and on the ecology), keys to orders and families, a descriptive part, a bibliography, a glossary, and an index, followed by the plates.

This paper deals with the slugs Alderia modesta (Lovén) and Limapontia depressa Alder &amp; Hancock, both very common in the intertidal zone of the Dutch salt-marshes. Van Benthem Jutting &amp; Engel did not mention them as native species in „Fauna van Nederland” 8, a monograph on Dutch Opisthobranchia, published in 1936. Alderia and Limapontia do not belong to the order of Nudibranchia, but to a separate order, Saccoglossa (Ascoglossa). They possess an uniseriate radula, the worn teeth of which fall in a pouch (saccus, ascus). Their way of life is different, the Nudibranchs feed mainly on hydroids, sea anemones, bryozoa, sponges, etc.; only a few species e.g. Polycera quadrilineata O. F.

Deze porfieroblasten zijn geen latere vormingen, doch behoren tot de oorspronkelijke metamorphose van deze schisten. Het oostelijke of interne deel bestaat overwegend uit granieten, amfibolieten en glimmerschisten. De metamorfosegraad is hier meestal hoger dan in het externe deel, zoals blijkt uit het anorthietgehalte van de plagioklaas en uit de aanwezigheid van de mineralen granaat,...

Hen inwoner van Leiden met belangstelling voor floristiek loopt gevaar om te versomberen. Hij heeft in zijn omgeving de min of meer vaste vindplaatsen van een hoogst bescheiden aantal zeldzame planten, waarmee hij eventuele gasten van elders desgewenst, in het juiste seizoen, kan confronteren, maar overigens leeft hij vrijwel te midden van een tot wanhoop drijvende cultuursteppe, enkele moeilijk toegankelijke terreinen (Kaaggebied!) niet te na gesproken. Wanneer zulk een florist zijn gedrukte stemming eens extra wil accentueren bladert hij in Molkenboer en Kerbert’s Flora Leidensis. Hij verneemt daaruit hoe anders zijn ervaringen zouden zijn uitgevallen indien hij omstreeks 1840 geleefd had. (Zijn gemoedstoestand brengt mee, dat hij daarbij liefst over het...

Petrology of the Northern Adula Region, Switzerland (with particular reference to the Glaucophane-Bearing Rocks)
Provedor de dados: 16
Autores: Plas, L. van der.
Geological and petrographical investigations were carried out in the northern part of the so-called Adula Nappe, one of the deepest Pennine nappes. The area under consideration lies in the SE of Switzerland, near Vals, S of Ilanz. This area is situated north of the Lepontinic gneiss-region, the deepest part of the Alpine orogen. The rocks of the mapped area fall into four groups, viz gneisses; micaschists; amphibolites and allied rocks; and Mesozoic rocks, either of sedimentary or of igneous origin. The first three of these groups presumably represent metamorphic Hercynian or older rocks. Structurally three unites were distinguished, viz the Valserschuppen, the Fanellalappen and the Zervreilerlappen. The investigations clearly showed the important role of...

Some time ago Mr. G. M.

The Neede Clay, Needian of Dutch terminology (Van der Vlerk and Florschütz, 1950, p. 149), is characterized by the abundance of the freshwater molluscs Viviparus diluvianus (Kunth) and Valvata naticina Menke; the scanty remains of large mammals found in this deposit, representing Elephas antiquus Falconer, Cervus elaphus L., and Dicerorhinus merckii (Jäger), were described already half a century ago by Rutten (1909).

The morphology of ferns
Provedor de dados: 16
Autores: Holttum, R.E.
A fern plant consists of a stem, bearing leaves and roots. The leaves (or some of them) bear dehiscent sporangia, each sporangium containing unicellular spores, which are in most cases Wind-dispersed. A spore germinates to produce a small green plant called a prothallus. The Prothallus bears sexual organs ( archegonia and antheridia). After fertilization by an antherozoid, the female cell in an archegonium grows to form a new fern plant. The life cycle of a fern thus has two phases, asexual (the fern plant) and sexual (the prothallus). These phases are also called the sporophyte and the, gametophyle. The sporophyte is much longer-lived, larger and more diversified than the gametophyte, and its characters are mainly used in taxonomy. The following statement...

Revision of Cryptaspasma Walsingham 1900 (Lepidoptera, Tortricidae)
Provedor de dados: 16
Autores: Diakonoff, A.
The genus Cryptaspasma comprises moths of moderate or rather large size, mostly of a "dark and earthy appearance", as Edward Meyrick once characterized them. These insects usually are of different shades of purplebrown to bronze-brown, with suffused blackish spots or retination. Although distributed over the Tropics of the whole world the species follow the same type of colouring and markings everywhere. Certain species from Papua, e.g., are surprisingly similar to other from Africa, New Zealand or Peru ! Besides, this type resembles very closely that of an entirely different group of the Microlepidoptera, viz., that of the genus Acrolophus Poey, a Tineoid group from South and Central America. So close is this resemblance that Meyrick even suggested that...

A further extension of Elminius modestus Darwin on the west coast of France
Provedor de dados: 16
Autores: Crisp, D.J.
In previous publications Bishop &amp; Crisp (1957, 1958) described the distribution of Elminius modestus on the coasts of France, based on surveys made in 1953 and 1954. Further information including some observations made in 1955 was given by Bishop, Crisp, Fischer-Piette &amp; Prenant (1957). Elminius was shown to be centred on three main areas; the Channel coast east of Cap de la Hague, the river systems of North Brittany, and the Rade de Brest. Further south scattered individuals only were to be found, nowhere in sufficient abundance to allow the majority to breed. Bishop &amp; Crisp (1957) pointed aut that the scarcity of Elminius on this part of the Brittany coast was surprising, since there are numerous suitable estuaries and harbours and an...

Note on the plan for the Pteridophyte series of Flora Malesiana
Provedor de dados: 16
Autores: Holttum, R.E.
Ferns are by far the largest division of vascular cryptogams, and, for purposes of publication of Flora Malesiana, they will have to be subdivided in a series of parts. This necessarily raises the problem of taxonomic subdivision of ferns into families or other major taxonomic units, a matter on which there is at present no general agreement among pteridologists, except that the more primitive families are generally recognized as distinct groups. As regards the majority of ferns therefore no formal arrangement into families will be attempted. There is however a fairly general agreement that certain groups of genera (e.g. the Davallia group) are natural groups. It is the intention to arrange the genera of ferns in such groups, and to publish the...

The Aeschnine Genus Staurophlebia
Provedor de dados: 16
Autores: Geijskes, D.C.
The genus Staurophlebia was established by BRAUER (1865, 1866) from his species magnifica from Brazil, a name which later proved to be a synonym of reticulata (Burmeister 1839), (see under this species). In his notes on St. magnifica, HAGEN (1867) said that SELYS (MS) has proposed the genus name Megalaeschna for Aeschna reticulata Burm., Ae. gigas Rbr. (= reticulata), and Ae. gigantula Selys, a closely related new species which was subsequently described by MARTIN. However, Megalaeschna is a synonym of the earlier name Staurophlebia, as already pointed out by COWLEY (1935). In his classification of the aeschnines, SELYS (1883) includes the two subgenera Neuraeschna and Staurophlebia in his genus Staurophlebia s.l., while KIRBY (1890), CALVERT (1905), and...

Manual of Marine Meteorological Observations, Tenth edition.
Provedor de dados: 20
The Conference of Brussels, called in 1853, was the first International Maritime Conference ever held. It sponsored the idea that governments should foster systematic weather observations on ships, and should prepare and publish charts of the prevailing winds, ocean currents, average sea and air temperatures, and tracks of dangerous storms based on the additional data. With the introduction of radio and fast ships, weather information became of vital importance to safe and efficient ship operation. Many countries began regularly scheduled weather forecasts to ships in nearby waters.  Today, weather forecasts as well as charts are prepared from data collected through ship observations. Forecasts of weather and sea conditions arc prepared for ship operation,...

A NEW LOOK AT BUDGETING FROM THE STANDPOINT OF LINEAR PROGRAMMING
Provedor de dados: 31
Autores: Candler,   Wilfred V.
This paper will take a new look at budgeting. It will be argued that with the development of linear programming, budgeting can be seen to have several disadvantages as a research tool. The development of linear programming as an aid to farm management research will then be examined. This examination will lead to the development of a slight refinement of conventional budgeting methods. This refinement may reasonably be termed parametric budgeting.

PRODUCTION FUNCTION ANALYSIS OF A FERTILIZER TRIAL ON BARLEY
Provedor de dados: 31
Autores: McCarthy,   W.O.
Production functions of one type or another have been well explored and widely discussed, no less in the literature of agricultural economics than elsewhere. A particularly fruitful area of application in farm economics is the quantification of the relationship between fertilizer inputs and crop output. In this context currently in Australia and New Zealand, more than passing interest is being devoted to problems of experimental design and subsequent interpretation of results. (1) Another problem area relates to the choice of the most appropriate type of function to use. This note examines possible relevant functions for crop fertilization experiments. Subsequently, a set of empirical data are fitted and the derivation of the more elementary economic...

INVESTMENT ALLOWANCES FOR PRIMARY PRODUCERS
Provedor de dados: 31
Autores: Barton,   A.D.; Harcourt,   G.C.
The purpose of this article is to show that the scheme of investment allowances outlined below would be preferable to the present system of special depreciation allowances as a means of encouraging investment by primary producers, especially investment by low-income farmers. The need for increased primary production for balance of payments reasons is assumed and increased investment is the major means of bringing this about. (1) The main determinant of the ability of farmers to invest is the excess of their disposable incomes over the costs of maintaining a required standard of life. (2) The effectiveness of the above schemes depends largely upon the extent to which they increase these surpluses. The empirical studies to date suggest that special...

AUSTRALIAN TRADE POLICY: COMMENT AND QUESTION
Provedor de dados: 31
Autores: Crawford,   John G.
I have a threefold purpose:-  Firstly: to repeat and review briefly some of the things I have been saying in the last few months about Australian trade policy.  Secondly: to bring to light three or four of the more important questions or issues which arise in the course of a generalised statement of Australian trade policy. To comment in this way may give rise to rather unbalanced digressions: I believe the risk worth taking.  Thirdly: flowing readily enough from these two will come a plea for more public debate on policy issues. No less important will be a correlative plea for more work to be done by economists (using the Adam Smith concept of political economist) on the many important variables in the debate, about which more needs to be known.  I cannot...

U.K. AGRICULTURAL POLICY AND THE AUSTRALIAN FARM PROGRAMME
Provedor de dados: 31
Autores: Wadham,   Samuel.
The title of this paper forces me to begin with a consideration and definition of U.K. agricultural policy and further, inasmuch as any farm programme must be a long-term affair, I am more or less compelled to discuss whether the present U.K. policy is permanent or temporary. This requires some examination of that policy in the past, and of the way in which it developed. It may then be possible to make an intelligent guesstimate of the future.

EQUATIONS RELATING THE COMPOSITION OF BEEF CATTLE HERDS TO CERTAIN BASIC DATA
Provedor de dados: 31
Autores: Granger,   W.; Walsh,   J.D.
Equations are derived which relate the components of beef cattle herds to certain basic data. By enabling the construction of series of models to represent real or theoretical situations the equations provide a useful tool for analysing the influence of selected factors upon herds or populations--particularly upon their components, turn off, and practicable rates of selection. The technique should be useful in economic, animal husbandry, and genetic studies, where decisions have to be taken upon management policy, and in evaluating proposals for private or public investments in station improvements or utilities for the cattle industry.

DROUGHTS, FODDER RESERVES AND STOCKING RATES
Provedor de dados: 31
Autores: Mauldon,   Roger G.; Dillon,   John L.
The present article relates to pastoral firms in a drought-prone environment. For such firms, it explores the economic relationship between stocking rates, drought possibilities and fodder reserves. (1) The analysis shows that an optimal stocking rate can be ascertained for any given pattern of drought incidence. Using Queensland data, an empirical application covering a range of fodder, livestock and livestock product prices is presented. Nothing is said of the macro aspects of fodder storage for drought relief; nor of the optimum level of livestock population on an aggregate basis. Likewise, the analytics of supplementary feeding for production--as distinct from drought feeding for survival--are not explored on either a micro or a macro basis. Still, the...

Autores: Gomes,Frederico Pimentel; Nogueira,Izaias Rangel.
The authors studied the rainfall in Pesqueira (Pernambuco, Brasil) in a period of 48 years (1910 through 1957) by the method of orthogonal polynomials, degrees up to the fourth having been tried. None of them was significant, so that it seems that no trend is present. The mean observed was 679.00 mm., with standard error of the mean 205.5 mm., and a 30.3% coefficient of variation. The 95% level of probability would include annual rainfall from 263.9 up to 1094.1mm.

Autores: Gomes,F. Pimentel; Abreu,Clovis Pompílio de.
The authors discuss a formula for the determination of the most profitable level of fertilization (x*). This formula, presented by CAREY and ROBINSON (1953), can be written as: x*= (1/c) log cx u L10 + (1/c) log wu _______ ___ 1-10 x u t being c the growth factor in Mitscherlich's equation, x u a standard dressing of the nutrient, L 10 the Naeperian logarithm of 10, u the response to the standard dressing, w the unit price of the crop product, and i the unit price of the nutrient. This formula is a modification of one of the formulas of PIMENTEL GOMES (1953). One of its advantages is that is does not depend on A, the theoretical maximum harvest, which is not directly given by experimental data. But another advantage, proved in this. paper, is that the...

Due to the great importance of coffee to the Brazilian economy, a good deal of the work carried out in the "Laboratório de Isótopos", E. E. A. "Luiz de Queiroz", Piracicaba, S. Paulo, Brazil, was dedicated to the study of some problems involving that plant. The first one was designed to verify a few aspects of the control of zinc deficiency which is common in many types of soils in Brazil. An experiment conducted in nutrient solution showed that the leaf absorption of the radiozinc was eight times as high as the root uptake; the lower surface of the leaves is particularly suited for this kind of absorption. Among the heavy metal micronutrients, only iron did not affect the absorption of the radiozinc; manganese, copper, and molybdenum brought about a...

The authors study the insect population that visit the mango trees and search for their pollinizing activity. Prior operations showed that very few bees (Apis mellifera) visited the flowers of mango trees. It was known that the percentage of fecundation is low (Simão 1955), Popenoe (1929), Spencer and Kennard (1955), Lynch and Mustard (1955), Ruehle and Ledin (1955), so that the authors wented to Know if insects could be responsible for this. Insects were collected from mango trees, belonging to 10 orders, which, on the whole are not pollinizing agents. Bees were not collected, 21% were Hymenoptera, 20% were Diptera, 13% Hemiptera, 10% Coleoptera, 3% Blattariae and smoller percentages belonged to other orders.

Autores: Sousa,J. S. Inglez de.
A videira Niagara, de bagas brancas e arredondadas, originou-se de cruzamento em que participaram as espécies Vitis labrusca L. e V. vinifera L. Foi introduzida no Brasil em 1894 e, a partir de 1910, começou a ser largamente difundida pelos vinhedos brasileiros, notadamente nos do Estado de São Paulo, onde é considerada a variedade de maior importância econômica. Existem neste Estado cerca de 27 milhões de pés de Niagara, que produzem anualmente perto de 50 mil toneladas de uvas frescas, representando um valor aproximado de 500 milhões de cruzeiros. A partir de 1933 foram observadas na região de Jundiaí, Estado de São Paulo, al-algumas mutações somáticas da Niagara original. Pela ordem em que tais mutações apareceram, é a seguinte sua relação: 1) BAGA...

Autores: Arruda,Hermano Vaz de.
No presente trabalho são apresentados os resultados de duas experiências de adubação de milho, instaladas no ano-agrícola 1956-57 em terra-roxa da Estação Experimental de Ribeirão Prêto, com o objetivo de investigar comparativamente o efeito da aplicação de dois adubos azotados, Salitre do Chile e sulfato de amônio. Êstes adubos foram aplicados em duas doses, 80 e 160 kg/ha de N. A aplicação do nitrogênio para a dose 80 foi em cobertura e dividida em três partes, 30, 30 e 20 kg de N, aplicados aos 30, 60 e 80 dias após a germinação, respectivamente. Para a dose 160 aplicou-se o dôbro, em cada época. Todos os canteiros da experiência haviam recebido PK nos sulcos de plantio, na dose de 80 kg/ha de P2O5 e de K2O com exceção de um que era testemunha, sem...

Autores: Carvalho,A.; Mônaco,L. C.; Antunes Filho,H.
As análises das produções de cafeeiros constituintes de diversas progênies, principalmente de café Bourbon Vermelho, com produções controladas por 12 a 15 anos. mostraram acentuada variabilidade na produção, o mesmo ocorrendo entre cafeeiros F1 derivados de hibridações entre plantas selecionadas. A fim de avaliar as causas dessa variação foram escolhidas, em quatro progenies S1 e em três híbridos F1, cafeeiros com as mais altas e as mais baixas produções, bem como uma planta em cada progênie com produção correspondente à classe mediana, a fim de servirem de plantas matrizes para derivação de progênies correspondentes às gerações S2 e F2. Estas foram plantadas, em 1953, em um ensaio comparativo, onde também foram incluídas novas progenies S1 e F1 dos mesmos...

Autores: Carvalho,Alcides.
Vários conjuntos de mudas de café da Etiópia foram recebidos em Campinas em 1952 e 1953, através do Departamento de Agricultura dos Estados Unidos da América do Norte. Entre êsses cafeeiros foram observadas diversas variações, as quais vêm sendo analisadas sob os aspectos morfológico e genético. Verificou-se que o café recebido com a denominação de Eritrean Moca não é um híbrido da variedade mokka de Coffea arabica, mas intientifica-se com o mutante semper-florens e é homozigoto para o par de alelos sfsf. Pelas hibridações realizadas com a variedade murta notou-se que o alelo t, que caracteriza o café Bourbon, é freqüente no material provindo da Etiópia, embora também af ocorram plantas da variedade typica de constituição TTNaNa.

Provedor de dados: 53
Autores: Mendes,Luiz O. T.
Para fins de seleção de seringueiras (Hevea brasiliensis Muell.-Arg.) de elevado rendimento, foi feito um estudo da produtividade individual, durante um ano, de 31 plantas com idade aproximada de 33 anos. As sangrias foram feitas a meia espiral, em dias alternados, de março de 1943 a março de 1944, com interrupção de junho a setembro. Foi de pronto constatada grande variabilidade na capacidade de produção das plantas em aprêço. Os resultados mostram que, para a população estudada, uma quinzena de sangria foi suficiente para revelar qual a planta de maior produtividade. Após um ano de sangria essa mesma planta se mantinha em primeiro lugar, pouco se alterando a ordem das primeiras colocadas, pela sua capacidade de produção, quer quando classificadas após...

Autores: Medina,Dixier M.; Conagin,C. H. T. Mendes.
Diversas pesquisas foram realizadas com a finalidade de esclarecer as causas da improdutividade de Coffea Dewevrei, da qual possuímos em coleção as seguintes variedades: Abeokutae, Dybowskii, Bxcelsa e Dewevrei. Um grande número de auto-polinizações e cruzamentos foi realizado dentro e entre variedades. Com êsse trabalho ficou comprovado que as auto-polinizações são absolutamente improdutivas e que só são produtivas as combinações entre certos clones. Das observações citológicas realizadas sôbre a formação e desenvolvimento do saco embrionário e sôbre o pólen concluiu-se não existir qualquer anormalidade capaz de impedir a fertilização. Chegou-se à conclusão de que também nesta espécie diplóide existe o fenômeno da incompatibilidade genética, cujo...

Autores: Mendes,Luiz O. T.
A seringueira é uma planta cujas estacas normalmente enraizam com muita dificuldade. Daí o autor ter estudado uma maneira de multiplicar essa planta por meio de estacas, pelo estrangulamento de sua haste, com um fio de arame bem apertado. Decorridos vários dias após tal operação, as estacas são cortadas logo abaixo do callus formado e plantadas em areia. Vários ensaios foram realizados no Instituto Agronômico do Norte, para estudar em que lugar da haste deve ser feito o estrangulamento, bem como quantos dias depois da operação devem as estacas ser colhidas. Os resultados mostram que o estrangulamento deu melhores resultados quando feito logo abaixo de uma gema ou do ponto de inserção de uma ou de duas fôlhas, e que a colheita das estacas deve ser feita...

Intervalos entre tratamentos inseticidas
Provedor de dados: 53
Autores: Mendes,Luiz O. T.
Admitindo que as populações de insetos crescem segundo a lei logística, o autor, partindo de uma equação que a descreve, apresenta uma fórmula que permite estabelecer o intervalo de tempo que deve decorrer entre os tratamentos inseticidas, para que a infestação por uma praga não exceda um limite pré-estabelecido. O valor de t (intervalo, expresso em número de gerações do inseto) depende do potencial biótico da espécie, da eficiência do inseticida e do nível de infestação que se estabelecer como máximo permissível. Os resultados teóricos são discutidos e mostram a possibilidade de sua comprovação por meio de populações de insetos mantidas em laboratório, como fase preliminar à sua aplicação no campo.

O presente ensaio, realizado com a var. bourbon de Coffea arabica, além de dar informações sôbre a produção dos cafeeiros protegidos dos insetos polinizadores, permitiu também averiguar o comportamento de várias espécies de abelhas e obter outras informações correlatas. Constatou-se, assim, que o néctar da flor é ainda abundante mesmo 24 horas após a antese e que o teor de açúcar do néctar é elevado, da ordem de 38%, em média. Apis mellifera foi a espécie mais freqüentemente encontrada coletando o néctar e o pólen. Em dias chuvosos, muitas das abelhas dessa espécie apenas coletam o pólen. Das abelhas indígenas, somente Plebéia sp. e Nannotrigona (Na.) testaceicomis e Melipona quadrifasciata foram encontradas colhendo o pólen. Com tempo bom, as abelhas...

Influência da adubação e da fumigação do solo, na incidência de nematôides em tubérculos de batatinha
Provedor de dados: 53
Autores: Boock,O. J.
Dentre as causas que podem levar ao fracasso a cultura da batatinha (Solanum tuberosum L.) no Brasil, sobressaem as devidas aos nematóides causadores de galhas ou pipoca Meloidogyne incognita (Kofoide &amp;amp; White, 1919) Chitwood, 1949. Os tubérculos, quando atacados, tornam-se impróprios ao plantio e ao consumo apodrecendo rapidamente.

Provedor de dados: 53
Autores: Arruda,Hermano Vaz de.
No presente trabalho é apresentado um método de pesquisar a necessidade de fileiras de bordaduras, num ensaio de variedades de feijão. O método baseou-se na concordância das análises parciais (fileiras úteis e fileiras de bordaduras) com a análise do total (úteis mais bordaduras), verificada através dos valores de F e dos coeficientes de variação. A concordância das três análises, para os citados valores, indica uma correlação entre as produções das fileiras centrais e de bordaduras e, portanto, a dispensa destas últimas. Como complemento da análise anterior aplicou-se a análise da covariância, considerando x a produção das fileiras de bordadura e y a das fileiras centrais. Com base nesta análise calcularam-se os coeficientes de correlação entre as médias...

Os dados obtidos mostraram que a estirpe I.A. 78 apresentou os melhores resultados na redução da acidez volátil dos vinhos obtidos.

Fermentação de mosto de uva com leveduras regionais selecionadas
Provedor de dados: 53
Autores: Toledo,Odette Zardetto de; Teixeira,Cybo G.
Com o fim de selecionar fermentos que produzissem vinhos com grau alcoólico satisfatório e com baixo teor de acidez volátil e aldeído acético, estudou-se o comportamento de cinco leveduras, escolhidas dentre 25 já ensaiadas anteriormente. Os fermentos I.A. 78 e I.A. 199 mostraram-se bastante promissores, podendo ser utilizados com sucesso nas cantinas industriais.

Determinação da velocidade de infiltração da água no solo, por meio de diagramas de pluviografos e limnígrafos
Provedor de dados: 53
Autores: Bertoni,José.
Neste trabalho são apresentados os valores da velocidade de infiltração, obtidos com os dados de perdas por erosão dos talhões de comprimento de rampa, da Estação Experimental de Conservação do Solo, em Clarinda, Iowa, nos Estados Unidos. Usando os dados de intensidades de chuva e enxurrada, a velocidade de infiltração foi determinada pelo método gráfico de Sharp e Holtan para as 10 maiores chuvas, com apreciável enxurrada, que ocorreram durante um período de cinco anos. As 10 chuvas foram selecionadas com base na sua duração, intensidade e época do ano. Os problemas do cálculo da velocidade de infiltração com os dados de talhões de perdas por erosão e algumas das limitações dos valores determinados são apresentados.

Adubação do algodoeiro VI: ensaios com doses crescentes de fósforo
Provedor de dados: 53
Autores: Ramos,Ismar; Neves,O. S.; Freire,E. S.
Neste artigo os autores apresentam os resultados obtidos em 13 ensaios de adubarão do algodoeiro com doses crescentes de fósforo, empregadas sòzinhas ou na presença de azôto e potássio. Os ensaios foram conduzidos entre 1943-44 e 1947-48 em diferentes localidades da zona algidoeira do Estado de São Paulo, abrangendo vários tipos de solo. Provavelmente por ter sido aplicada em contato com as sementes, a adubação com azôto e potássio reduziu o "stand" em cêrca de 50% dos casos, e seu efeito sôbre a produção, em média dêsse grupo, foi apenas um têrço do obtido no grupo em que o "stand" não sofreu tal prejuízo. Tanto na presença como na ausência de azôto mais potássio a resposta média ao fósforo foi muito boa quando se usou a dose de 40 kg/ha de P2O5, e ainda...

Ensaios de profundidade de plantio da batatinha
Provedor de dados: 53
Autores: Boock,O. J.
Dadas as diferentes condições de clima e solo em que é feita a cultura da batatinha no Estado de São Paulo, procurou-se estudar quais as profundidades de plantio mais adequadas. Para isso foram instaladas experiências em que se compararam as profundidades de 5, 10, 15 e 20 centímetros e em duas épocas bem distintas, a "das águas", que vai de setembro a fevereiro, e a "da sêca", de março a agôsto. Pelos resultados obtidos chega-se à conclusão de que o plantio a 5 cm não é recomendável, principalmente quando feito em período pouco chuvoso e sem o concurso da irrigação. A essa profundidade a porcentagem de falhas aumenta, o nascimento é retardado, o esverdeamento e queimadura dos tubérculos produzidos são mais acentuados. As profundidades mais indicadas estão...
