Poliploidía en Opuntia spp
Provedor de dados: 32
Autores: Sosa Chávez, Rubén; Acosta C., Aristeo.
El nopal (Opuntia spp.) es una de las plantas más valiosas de las zonas áridas, tanto por la producción de forraje para el ganado, como la alimentación humana. No existiendo información sobre la citología de las especies O. robusta, O. amyclaea y O. megacantha, para el establecimiento de bases firmes para un programa de mejoramiento se efectuó el presente estudio. Los estudios citológicos y preliminares morfológicos sugieren la separación de varios "grupos" o "especies" que han sido considerados dentro de una sola especie, mostrando además diferentes grados de poliploidía dentro de dicho(s) grupo(s). Se dan también los números cromosómicos de las "especies" estudiadas.

Provedor de dados: 32
Autores: Echegaray Alemán, Alfredo; Ortega Torres, Enrique; Aguilera, Nicolás.
El estudio sobre el movimiento, la nitrificación y las posibles pérdidas de nitrógeno de tres fertilizantes (urea, sulfato de amonio y nitrato de amonio) bajo condiciones de laboratorio de tres suelos del Estado de México y uno del estado de Sonora, indican que el amonio se localiza en la capa superficial del suelo, los nitratos se mueven rápidamente, siendo precolados sin dificultad y el nitrógeno uréico ocupa una posición media en cuanto a su facilidad de percolación.

La potencia de la prueba en los diseños experimentales
Provedor de dados: 32
Autores: Romero Chávez, Sigifredo; Carney, Edward J.; Rojas, Basilio.
El número de repeticiones que se emplea en los diseños experimentales está íntimamente relacionado con la potencia de la prueba y su importancia radica en la determinación del número de repeticiones adecuado al tamaño de las diferencias que se espera existan entre los tratamientos. Esta importancia puede decirse que es de carácter económico debido a que, cuando se emplea un número de repeticiones mayor que el necesario, se desperdician recursos que bien podrían emplearse en otra investigación. Por otro lado, si el número de repeticiones es menor que el necesario, puede llegar a concluirse que en una investigación no hay diferencias significativas, cuando de hecho existen, porque el experimento no tuvo la potencia de prueba necesaria. El presente estudio...

Autores: Gómez Aristizábal, Alvaro; Fernández González, Ramón.
El momento apropiado para aplicar el riego es un factor decisivo en el uso racional del agua de riego. El presente estudio indica que tanto la apertura estomatal, como la turgencia relativa, reflejan las condiciones de energía de la humedad del suelo, sugiriendo el valor práctivo del método para establecer un criterio que fije el momento de regar.

Ideas básicas en la programación lineal
Provedor de dados: 32
Autores: Tucker, Henry.
La programación lineal es una técnica utilizada para encontrar soluciones a problemas que involucran una serie de desigualdades lineales con alguna función objetiva. Generalmente las desigualdades establecen una relación entre los ingresos o egresos y algunos recursos limitados. La función objetiva trata, por lo común, de maximizar las ganancias o de reducir al mínimo los costos. Bajo condiciones muy amplias, el concepto de la programación lineal puede aplicarse a problemas tales como la mezcla de alimento para raciones, para un costo mínimo, reuniendo ciertos requerimientos nutritivos o fijando recursos (tierra, trabajo, capital) a empresas agrícolas para obtener ganancias óptimas. Para formular las ecuaciones se requiere obtener coeficientes para...

Biología y ecología del descortezador del pino Dendroctonus valens Lec. (Coleoptera: Scolytidae)
Provedor de dados: 32
Autores: Rose Chaffin, William Edwin; Ramírez Genel, Marcos; Krogstad, Blanchard O.
El descortezador D. valens es un predator secundario de tocones y de la porción basal de los árboles ya bajo el ataque de un descortezador primario en la región central de México. La asociación con D. frontalis es la más frecuente en los bosques de pinos de la parte central de México y bajo estas condiciones no se considera su importancia económica. Solamente en el Estado de Chihuahua, en la parte norte de México, este insecto es una plaga primaria y por lo tanto, de importancia económica. El presente trabajo es un estudio sobre la ecología y el ciclo biológico de D. valens como una contribución al conocimiento de esta especie poco mencionada en la literatura.

Infiltración genética entre Tripsacum zopilotense Hern. y Rand. y Tripsacum maizar Hern. y Rand.
Provedor de dados: 32
Autores: Curtis Patiño, Jorge; Miranda Colín, Salvador; Kato Y., Takeo A.
La infiltración genética entre T. zopilotense y T. maizar puede utilizarse para agregar información al esclarecimiento del problema que se tiene en torno a la taxonomía de las especies mexicanas del género Tripsacum. En este sentido, los resultados morfológicos y citológicos obtenidos permiten considerar: que no existen mecanismos de aislamiento reproductivo entre ambas especies; que como consecuencia de su hibridación existe, en la actualidad, infiltración genética entre ellas; que la variación morfológica, citológica y poliploidía se deben fundamentalmente a mutaciones espontáneas, recombinación génica, selección y disturbios ecológicos.

Autores: Miranda Colín, Salvador.
Tomando en cuenta los distintos hábitos de crecimiento que muestran las actividades de frijol, consideradas en el presente estudio y otras variedades no incluidas en el mismo, se postula que hay por lo menos 5 alelos distintos gobernando el hábito de crecimiento en P. vulgaris L. De los resultados obtenidos se concluye que el hábito de crecimiento está gobernado por una serie alelomorfos múltiples donde el alelo G3 domina sobre los alelos G1 y g. y el alelo G1 domina a su vez sobre el alelo g.

Vigor híbrido y su abatimiento en ocho cruzas de sorgo para grano
Provedor de dados: 32
Autores: Infante Heller, Leslie; Márquez Sánchez, Fidel; Miranda Colín, Salvador.
Por mucho tiempo se consideró que en las plantas autógamas no se manifestaba el vigor híbrido. Su manifestación cuantitativa depende de la constitución genética de los progenitores considerados y de la acción génica ya que puede llegar a tener valores de cero o negativos. El objeto del presente trabajo es investigar si las condiciones climáticas de las zonas templadas y calientes de México permiten la expresión de la heterosis en sorgos híbridos de primera generación en un porcentaje aceptable que signifique mayor producción y mejores ingresos para el agricultor.

Estudio genético de la resistencia del frijol a Pseudomonas phaseolicola (Burk) Dows
Provedor de dados: 32
Autores: Gallegos Barquín, César; Campos Tierrafría, Alfredo; Crispín M., Alfonso.
La bacteria Pseudomonas phaseolicola causa pérdidas de consideración al atacar los cultivos de frijol en algunas zonas de México. La incosteabilidad del control de esta enfermedad por medio químicos impone la necesidad de obtener variedades resistentes. Como primer paso hacia esta meta se planeó el presente trabajo con objeto de estudiar la herencia de la resistencia al ataque de P. phaseolicola. Como progenitor resistente se utilizó la variedad Canario 101 y como progenitor susceptible, la variedad Sanilac. De la cruza resultó, en la F2, un total de 1,346 plantas, de las cuales al ser inoculadas con la bacteria resultaron 735 resistentes y 611 susceptibles, según la escala de lecturas establecida. De acuerdo con  el método de X2 la segregación se ajusta a...

L'anchois (engraulis encrasicholus l.) des cotes d'Oranie
Provedor de dados: 5
Autores: Arrignon, Jacques.
Engraulis encrasicholus L. is a species that is captured all year long off the coasts of Algeria. The studied specimens measured from 8 to 19 cm. The average total length is 14 cm. Throughout the year, the average monthly size does not vary (12.6 to 14.7 cm for the entire species, 12.4 to 15.6 cm for bottom anchovies; the difference is greater for surface anchovies: 9 to 15 cm). During summer, the average is the highest and the most constant. Sizes have different modes during winter and spring. Average lengths are greater than those of the Atlantic specimens. This can be explained by the fact that the continental margin is narrower in the Mediterranean Sea, so that anchovies can find trophic areas closer to the shore (J. FURNESTlN, 1950)....

Distribution de Mytilicola intestinalis steuer le long des côtes françaises
Provedor de dados: 5
Autores: Brienne, H; Pairain, R.
Lorsqu'en 1950 une mortalité importante a affecté presque tous les parcs à moules de la Zélande, des examens ont été faits pour déceler la présence de Mytilicola intestinalis Steuer dans les moules des gisements naturels et des parcs de culture du littoral français. A cette époque, trois secteurs étaient fortement infestés :  les gisements de la Normandie;  les parcs et gisements de la côte de la Bretagne Ouest et Sud;  les parcs du littoral méditerranéen.  Beaucoup de zones mytilicoles en étaient indemnes ; d'autres en renfermaient des quantités variables.

Note préliminaire sur la morue du sud de la mer du nord et de la région du Pas-De-Calais
Provedor de dados: 5
Autores: Lefranc, Gérard.
The cod stock in the south of the North Sea and of the Pas-de-Calais consists mostly of young individuals (less than 4 years old) but growing fast, and thus showing a greater weight at the same age than the cods from more eastern parts of the Northern Atlantic Ocean. The fact that this population has grown greatly since 1963, presumably because of the harsh conditions of the winter 1962-1963, lead to a rapid development of the catches. Indeed, it has been observed that, despite a growth of the fishing effort, performances have slightly increased with the production now reaching about 10,000 tonnes per year and accounting for a large percentage of the cod unloaded in Boulogne. It is difficult to foresee the future of this stock, which can only remain stable...

Autores: Faure, Louis.
Parmi les coquillages comestibles, un des plus appréciés est la coquille Saint-Jacques, Pecten maximus, dont d'importants gisements se trouvent sur les côtes bretonnes, principalement en rade de Brest, en baie de Saint-Brieuc et dans la région de Belle-Ile.  Les bancs de la rade de Brest ont déjà fait l'objet d'études parues en 1952 et 1956 dans le Bulletin d'Information de l'Office des Pêches maritimes et la Revue des Travaux de l'Institut des Pêches maritimes. Le "Roselys" a prospecté en 1965 ceux de la baie de Saint-Brieuc (résultats dans "Science et Pêche" n° 137); en 1966 il a continué l'étude de cette même baie et étendu ses travaux à la rade de Brest et aux coureaux de Belle-Ile.

The described red water phenomena, determined by the presence in waters of abnormally high densities of either Dinoflagellates or phototrophic bacteria Thiorhodaceae and Athiorhodaceae, provide very little information about the microbial associations developing during these crisis periods of strong seasonal character.Topographic, climatic and hydrologic conditions are of course necessary for the setting up of such phenomena (reduced circulation ecosystems, water warming, stratification or water stagnation). But besides these preliminary factors and their consequences on the alteration of the physico-chemical characteristics of waters, bacterial activities play an essential role in the primary or secondary ecosystem intoxication mechanisms that go together...

Ce travail, axé principalement sur le chalutage, a permis de préciser les possibilités des deux types d'engins nouveaux - chalut pélagique et chalut semi-pélagique - qui sont de plus en plus employés par les chalutiers de Boulogne ou de Fécamp. Il a été complété, dans tous les cas, par des observations sur la composition du stock des principales espèces exploitées, ainsi...

Nouvelle carte des abords du plateau continental entre les îles Shetland et Faeroe
Provedor de dados: 5
The results of the bathymetric measurements methodically conducted on board the two vessels of the Institute of Marine Fisheries "Président Théodore Tissier" and "Thalassa" enabled the publication in 1961 of charts 1 to 12 focusing on the region located between the Porcupine bank and Cap Finisterre and of chart N°17, in 1962, focusing on the North-Tampen sector, between Norway and the north of the Shetlands.A new chart, n°18, published in 1966, continues towards the south-west of the North-Tampen chart and gives the bathymetry of the region located between the north and west of the Shetlands and the south of the Faeroe Islands. It covers the sector located between latitudes 59°35' and 62°00' N and longitudes 0°00' and 7°10' W.It was established according...

La pêche au large aux filets maillants et trémails sur les côtes de Provence
Provedor de dados: 5
Autores: Bonnet, Marc.
Parmi les arts fixes, les trémails et les filets maillants à une seule nappe sont depuis longtemps utilisés par petits fonds sur les côtes françaises de Méditerranée. L'habitude a été prise de considérer ces engins comme ceux d'une pêche artisanale traditionnelle, essentiellement côtière, dont les apports sont de qualité mais faibles.  Pourtant l'emploi de telles nappes connait, depuis quelque temps, un développement assez remarquable. L'exploitation des fonds du large pour la pêche de la sole au trémail et du merlu au filet maillant en est la cause. Cette orientation nouvelle a nécessité l'adaptation de ces filets à des fonds relativement importants (75 à 150 m) et entraîné la modernisation des bateaux et de leur équipement; elle s'avère intéressante...

Pêches planctoniques superficielles et profondes en méditerranée occidentale (Campagne de la «Thalassa » -janvier 1961 entre les îles Baléares, la Sardaigne et l'Algérois) VII. . THALIACÉS
Provedor de dados: 5
Autores: Casanova, Jean-paul.
In this high sea sector, we identified 7 species of Thaliacea: one Pyrosorne (Pyrosoma atlanticum), three Salps (Thalia democratica, Salpa fusiformis, Pegea confoederata) and three Doliolids (Doliolum nationalis, Doliolina mulleri. Doliolum denticulatum).If the distribution of the first two groups did not bring any new knowledge concerning their distribution or their behaviour in the Mediterranean Sea, it was not the same for the third group.Indeed, we demonstrated the existence of close relationships between the distribution of doliolids and local marine circulation. As observed by TRÉGOUBOFF (1965) in the Villefranche-sur-Mer area where the modification of the layers by the easterly wind brought doliolids down to 1 800 m deep, we found them at more than...

Teneur en halogènes et salinités
Provedor de dados: 5
Autores: Raimbault, R.
Quand on fait agir du nitrate d'argent sur une eau contenant des halogènes (C1, Br, I) on obtient un précipité d'halogénures d'argent jusqu'à épuisement des halogènes. GAY-Lussac dès 1832 utilisa cette réaction comme base d'une méthode de dosage volumétrique. Par la suite un précieux complément fut apporté par MOHR : quelques gouttes d'une solution de chromate de potassium (ajoutées à l'échantillon) permettent de déceler d'une façon relativement nette la fin de la réaction. On trouvera dans n'importe quel manuel d'analyse le détail des phénomènes chimiques qui entrent en jeu au cours de ces opérations.

Etude théorique et pratique de  la pêche a la lumière
Provedor de dados: 5
Autores: Kurc, Georges; Blancheteau, Marc.
Light fishing is an extremely old practice. It most likely originates from distant times when a man, using a flaming torch next to a river, realised that fishes gathered next to the lightened bank. After that, night fishing, using a fire-or "clairon"-, developed in France and other countries. Different types of light generators were used: torches, burning coal positioned on a grid at the back of the boat, and more recently acetylene, fuel or propane lamps. Finally, for about a decade, electric generators using different tensions have been tried out to supply reflectors and produce a powerful and continuous brightness. In France, fire fishing has been practiced for a long time by Mediterranean fishers who, having replaced the traditional gillnet-called...

Caractérisation pratique du thon patudo (parathunnus obesus, lowe)
Provedor de dados: 5
Autores: Roger, Ed; Le Berre, Y; Crepey, J.r.
L'arrêté interministériel du 8 juin 1964 (J.O. 17-6-64) interdit, pour la préparation de conserves de thon, de mettre dans une même boîte plusieurs espèces de thonidés, même si chacune de ces espèces à droit à l'appellation "Thon".  Il importe donc que les fabricants de conserves de poissons soient à même de déterminer aussi exactement que possible les différentes espèces de thonidés qui leur sont livrées.  Si le germon, Germo alalunga (Gmel) - l'albacore. Neothunnus albacora (Lowe) - le listao ou bonite à ventre rayé, Katsuwonus pelamis (L.) - la bonite à dos rayé, Sarda sarda (Bloch) notamment, sont très connus, il n'en est pas de même du patudo, Parathunnus obesus (Lowe), qui est parfois confondu avec d'autres espèces et le plus souvent avec l'albacore.

Eléments de planctonologie appliquée

Autores: Furnestin, Marie-louise; Maurin, Claude; Lee, Jean Yongchul; Raimbault, René.
Fisheries oceanography, in its use of various disciplines necessary to the study of oceans, is driven to understand the relationship linking oceanic phenomena on the one hand, and marine animals and their exploitation on the other hand. Its purpose generally has no bearing on fundamental research. As a result, fisheries oceanography rarely finds in the data provided by this latter anything to enable the progress of its specific approach of halieutic problems. Thus, in most cases, fisheries oceanography has to build its own baseline research, following specific programs and methods. Another disadvantage derives from this state of things. The education provided to young oceanographers does not prepare them for tackling practical oceanography and they have to...

Pêche sans filet et théorie des tropismes
Provedor de dados: 5
Autores: Kurc, Georges; Blancheteau, Marc.
Recent ideas about fishing without a net have still not given way to a large practical application, but they bring back a theoretical question currently left alone: the question of tropisms. This question emerges from the evolution of the conceptions which led to these futuristic views from traditional methods, and that we are going to briefly consider.In cast net fishing, the fishing device goes to the fish: one wants it to stay still. Gillnet fishing on the contrary works with the mobility of the fish, which throws itself in the trap, if it has been positioned in the right way.A great improvement is the combined use of ring net and salted cod-roe, as the mobility of the fish is guided by the bait: there is a food attraction and thus a fish gathering...

Quelques observations sur la condition des huîtres portugaises (Crassostrea angulata LmK), dans le bassin d'Arcachon, les ruissellements des eaux qui draînent l'arrière-pays, la présence de sels de fer et un phénomène de coloration
Provedor de dados: 5
Autores: Le Dantec, Jean.
Nous avons précédemment montré que des diminutions du rendement ostréicole pouvaient être consécutives à des périodes de sécheresse, que les ruissellements dans la baie n'étaient massifs que de novembre à mai inclus par suite des variations du niveau de la nappe phréatique; que les fortes pluies de l'hiver 1960-61 avaient eu pour conséquences d'importants apports d'alluvions et la réapparition sur les terrains ostréicoles d'une couche de vase superficielle appelée localement « barotte », où pullulait une flore benthique très riche, et une revigoration momentanée de l'huître portugaise. Ces constatations nous ont incité à comparer au cours des années dernières l'évolution des chutes météoriques pendant la période novembre-mai et les fluctuations de la...

Les pêcheries et le milieu marin dans le secteur méditerranéen de la république Arabe Unie
Provedor de dados: 5
Autores: Gorgy, Samy.
Before 1958, hydrology and halieutic research in Egypt, was mainly restricted to the brackish lakes of the delta and the surroundings of Alexandria. They resulted in a number of publications gathered under the title "The fishing grounds near Alexandria" in the Notes and Memories of the Institute of Alexandria. The marine sector, coastal and off-shore, of Mediterranean Egypt stayed practically ignored by oceanographers. However, the increasing food needs of the United Arab Republic increased the interest of national public powers and scientists for the marine sector which should provide large quantities of food, fish and other marine animals, to the Republic's market. This is the reason why, in 1957, during the International Fishing Gear Congress of...

Les problèmes de la production d'huîtres plates en Bretagne
Provedor de dados: 5
Autores: Marteil, Louis.
Le développement de la production de jeunes huîtres plates est unanimement souhaité par les Pouvoirs publics et les organismes représentatifs de la Conchyliculture. On en justifie l'opportunité par la nécessité d'approvisionner en quantité suffisante les terrains d'élevage dont la surface, en Bretagne, a plus que triplé entre 1949 et 1964 et dépasse actuellement 5 000 hectares. Les quantités de semences nécessaires sont diversement évaluées : elles devraient atteindre 1 200 à 1 500 tonnes par an selon les uns, 2 000 tonnes selon les autres (1). Or les possibilités actuelles de captage en Morbihan ne semblent pas devoir être supérieures à 1 000 tonnes par année de "bonne production", ce qui représente déjà plus d'un milliard de naissains. Ce chiffre n'est...

La pollution bactérienne des eaux et des coquillages de l'étang de Thau - 1966
Provedor de dados: 5
Autores: Fauvel, Yves.
La qualité bactériologique des eaux de l'étang de Thau a attiré l'attention dès 1896. En effet, à cette époque, de nombreuses intoxications gastro-intestinales et même plusieurs petites épidémies de fièvre typhoïde enregistrées dans différentes régions de France, furent attribuées à l'ingestion de coquillages venant de la région sétoise.  Plusieurs enquêtes furent effectuées, qui constituèrent les premières observations faites dans ce domaine. Toujours discutées, parfois contestées, elles devaient se succéder presque sans interruption jusqu'à 1907 ; les noms de CHANTEMESSE, MOSNY, MOREAU et FABRE-DOMERGUE demeurent attachés. Il fallut les preuves irréfutables apportées par NETTER en 1907 devant l'Académie de Médecine pour que le danger constaté par la...

Salses-Leucate lagoon in Roussillon is a water table of around 5 300 ha. This lagoon is in fact divided into two areas: to the south is the Salses lagoon which represents around two thirds of the total surface, to the north is the Leucate lagoon. Both lagoons are separated by a series of shoals (they create the frontier between the two departments of Aude and Pyrénées-Orientales). Up until recently, the Salses-Leucate lagoon only communicated permanently with the sea through its northern part (through the "grau"-estuary-of Leucate), which was deepened a few years ago. Not long ago, the reparation of the grau Saint-Ange, in the southern area, enabled a more important and more regular input of marine water....

La pêche en Méditerranée, ses possibilités, son évolution au large des côtes françaises
Provedor de dados: 5
Autores: Maurin, Claude.
La réputation de la Méditerranée est depuis longtemps bien établie : c'est une mer pauvre. En France tout au moins cette réputation était d'ailleurs justifiée par les faits. Il y a seulement quelques années, nos côtes méditerranéennes ne produisaient annuellement qu'environ 8 000 tonnes, c'est-à-dire la soixantième partie des apports nationaux en poissons et crustacés ; ceci pour une longueur de côte représentant, Corse incluse, près du tiers de l'ensemble de notre littoral. Mais depuis les captures revêtent une importance de plus en plus grande, aussi est-on en droit de se demander s'il s'agit là d'un phénomène passager ou si l'on peut espérer en l'avenir de la pêche en Méditerranée. Pour répondre à cette question, il est nécessaire d'exposer :  1)...

Les recherches sur la Morue et sur sa pêche, en France, sont l'oeuvre quasi exclusive de l'Institut scientifique et technique des Pêches maritimes, dénommé jusqu'en 1953 Office des Pêches. C'est après la guerre de 1914-1918 que furent réellement abordés sous leur aspect scientifique les problèmes de la pêche à la morue sur les bancs de Terre-Neuve. Un effort de coordination des méthodes et des programmes fut fait en 1920 par la création du "Deep Sea marine Fishery Investigations Committee" qui groupa les Etats-Unis, le Canada et Terre-Neuve, auxquels se joignit la France en 1922.

Automatic Water Control Structures for Surface Irrigation (Summarized)
Provedor de dados: 18
Autores: Humpherys, A.S.
Many improvements have been made in irrigation methods  and equipment in recent years. However, surface irrigation has not benefited from automation and still requires much hand labor. In addition to this high labor requirement, an excessive amount of water is often used. This is particularly true in areas where water is relatively cheap and labor is scarce. Further improvement in surface  irrigation methods and equipment using mechanized automated  control structures will enable the farmer to apply water with a  minimum of labor and to obtain maximum use from the water, thus conserving his resources.

Besides, there were in the Leiden Museum some unidentified colonies, obtained in Malayan waters. These, too, are now recorded. Several authors have already pointed out how difficult it is to identify Dendronephthya, owing to the unsatisfactory description by some previous authors, and because of the great number of variations within the same species.

Montane pollen from the Tertiary of NW. Borneo
Provedor de dados: 16
Autores: Muller, J.
In NW. Borneo thick series of Tertiary sediments occur which are rich in fossil pollen and spores. The majority of these plant microfossils were derived from the various types of tropical lowland vegetation such as mangrove (Muller, 1964), mixed peat swamp forest and mixed Dipterocarp forest. Some pollen types, however, can be traced to microtherm elements in the montane vegetation. As these cannot have migrated through tropical lowlands, their past distribution is of special interest. It is the purpose of this note to review the stratigraphic occurrence of these montane pollen types and discuss briefly the phyto-geographical significance of the data. The sediments which contain the microfossils can be roughly divided in a near coastal and deltaic facies,...

The Malvaceae have always enjoyed a vivid interest from botanists, in particular on account of the fact that many species have showy flowers and are appreciated as ornamentals throughout the world. In addition many species are of outstanding economical value, e.g. in the genera Gossypium and Hibiscus. Finally several species are weeds which have been dispersed by human agency far beyond their original areas of distribution and thus have had more chance to attract the attention of collectors. The wide variability of most species has offered annoying difficulties to botanists when trying to delimitate these species or their infraspecific taxa, resulting into an alarming accumulation of names. Despite the often painstaking studies by many botanists, either on...

La nomenclature botanique n’échappe pas à cette exigence et depuis que C. Linné généralisa, en 1753, la nomenclature binominale, le besoin s’est fait sentir de compléter et de préciser, sur le plan international, les principes et les règles établis par l’illustre botaniste suédois.

Some notes on the delimitation of genera in the Campanulaceae. II
Provedor de dados: 16
Autores: Gadella, Th.W.J.
1. The chromosome numbers of 38 species belonging to 11 genera of the tribe Campanuleae of Schönland’s system were determined. 13 of these species had not yet been investigated before. 2. A discussion is given of the differences between the present author’s results and those of other authors. 3. The systematic position of the species of Campanula with the diploid chromosome number 2n = 28 is reviewed. Some arguments are presented in favour of transferring Campanula erinus L. and Campanula drabifolia Sibth. to Dumortier’s genus Roucela. 4. A hypothetical explanation of the origin of the chromosome numbers 2n=28, 30, 32 and 34 of the genus Campanula is given. 5. The inclusion of Specularia perfoliata A. DC. and Specularia biflora Fisch. et Mey. in Triodanis...

Jaoa and Jaosaccion (Chlorophyceae, Ulotrichales)

Autores: Hoek, C. van den.
Recently I (Van den Hoek, 1966) proposed the new name Jaosaccion for the chlorophycean genus Coelodiscus Jao (1941), which is a later homonym of Coelodiscus Baillon (1858). Jaosaccion, in its turn, appears to be a synonym of Jaoa Fan (1964).

From botanical biography towards animal iconology

Autores: Verdoorn, Frans.
This essay is mainly a restatement of the biohistorical ideology such as we developed it during recent years. At a recent international congress, I tried to present this in a detached, logical way (1965). At other times, I endeavoured to clarify it by using a case history (1964). In both cases, certain things remained unexplained and I will now try to elucidate the development of our biohistorical ideology along somewhat different lines. In doing so I shall avoid unnecessary personal reminiscences, but some facts of a personal nature or relating to the development of our Institute necessarily will have to be recapitulated in this connection. Many factors are involved, ranging from the increase in our staff, to the augmenting interests of our students...

In our revision of Caprifoliaceae in Fl. Mal. I, 4 (1951) 175 seq. we omitted to mention Weigelia fallax described by Miquel from Lembang, West Java, collected by Korthals. The specimen was concealed among cultivated specimens and turned up recently. There is no doubt that this specimen is derived from an ornamental in the Javanese hills. We have sent this material to Prof. Hara who found it conspecific with Weigela coraeensis Thunb. It is often cultivated in Japan, especially as a hedge plant.

The genus Arthropteris J. Sm. in Malesia
Provedor de dados: 16
Autores: Holttum, R.E.
Arthropteris is a small genus of the Old World tropics (and southwards to New Zealand) the affinity of which is not clear. It shares with Oleandra and Elaphoglossum the character of outgrowths from the rhizome (phyllopodia) to which the stipes of fronds are jointed, and also has peltate rhizome-scales comparable with those of both genera. One group of species closely resembles Nephrolepis in shape and articulation of pinnae and in form and position of sori, another group has the frond-form and soral form of Thelypteris, and a third has sterile fronds so like those of Teratophyllum that they might be mistaken for that genus; the slender dorsiventral rhizome in all species is comparable with that of Teratophyllum, though the anatomy is different in detail.

When revising the acrostichoid genera Bolbitis and Egenolfia from the Old World for my thesis, I came across Acrostichum neglectum F. M. Bail. This species, which was successively transferred to the genera Leptochilus and Campium, has the essential characters of a blechnoid fern. On account of the differences found between A. neglectum and the other blechnoid ferns, it seems necessary to create a new genus to accommodate it, a point of view shared by Prof. Holttum, who gave me valuable advice for this study. I am indebted to Mr L. S. Smith of the Botanic Museum and Herbarium, Brisbane, for the loan of the collections of this species, to Mr J. H.

The amphipod, Gammarus tigrinus Sexton, 1939, introduced in the Netherlands (Crustacea)
Provedor de dados: 16
Autores: Nijssen, H.; Stock, J.H.
An alien amphipod, Gammarus tigrinus Sexton, has been observed in the Netherlands, mainly in oligohaline waters. It has had an “explosive” development in the Yssellake (the former Zuydersea) and occurs also in a great number of inland waterways in the province of North-Holland (fig. 1). It co-exists with, and often outnumbers, the local gammarids, G. pulex, G. zaddachi and G. duebeni. It is expected that the extension of its range will continue next years; fig. 2 illustrates the range of this introduced species in autumn 1965. Since Irish specimens of G. tigrinus were released in 1960 in the Yssellake, it is not clear whether the Dutch populations originate from the Irish stock, or whether that they were accidentally, e.g. in ballast tanks, carried to the...

Bistella Adans. versus Vahlia Thunb. (Vahliaceae)
Provedor de dados: 16
Autores: Bullock, A.A.
The somewhat peculiar genus Vahlia Thunb. (1782) was formerly regarded as an anomalous member of the Saxifragaceae, but in 1959 it was segregated as the monotypic family Vahliaceae by Dandy (in Hutchinson, Fam. Fl. Pl. ed. 2, 1: 461). The genus includes about three species, all of them highly variable in stature, flower size, and indumentum; this has resulted in the description of more than twenty “species”, whose names now appear in synonymy. This note, however, is chiefly concerned with the generic name, since it appears that Vahlia Thunb. is not correct under the Code and must be replaced by Bistella Adans. (1763). In the synonymy under the new combinations, all the relevant names so far traced are included, but it may well be that an experimental...

Recently, I transferred Ectochaete endophytum to Coelodiscus Jao (van den Hoek, 1965). Dr. R. C.

O. Schwarz (in Repert. Spec. Nov. Regn. Veg. 47: 288. 1939) was the first in recent years to draw attention to the Genera Plantarum Vocabulis Characteristicis Definita of N.

Fuchs (in Verh. Naturf. Ges. Basel 72: 344-345. 1961), however, argue that none of the names in Wolf’s work can be regarded as validly published. A study of the work and the others associated with it (Wolf, Concordantia Botanica, 1780; Genera et Species Plantarum Vocabulis Characteristicis Definita, 1781) has led me to the opposite conclusion, and in my view some twenty generic names are in...

On the petrography of the Lancara Formation from the Sierra de la Filera (Spain)
Provedor de dados: 16
Autores: Meer Mohr, C.G. van der; Schreuder, G.A.N.H.
The sediments of the, Cambrian, Lancara Formation show features which suggest their deposition in a shallow marine environment. The occurrence of stromatolites might indicate that some sediments were deposited in an intratidal environment. The gradual change, upward in the stratigraphie section, from stromatolite deposits via calcarenites to argillaceous limestones and shales is being interpreted as a transgressive marine sequence. The possibility of a penecontemporary dolomitization of the lower part of the formation followed by secondary, post Namurian?, dolomitization is suggested.

Reproduction in the Lesser Horseshoe Bat (Rhinolophus hipposideros hipposideros Bechstein, 1800)
Provedor de dados: 16
Autores: Gaisler, Jiří.
The present paper gathers the results of a morphological study on 149 specimens of Rhinolophus hipposideros, and of ecological investigations on additional material, incl. some 5,000 banded individuals of the same species. Brief description of the reproductive organs of both sexes is given. The reproductive organs of the sexually mature (adult) and the sexually immature grown-up (subadult) individuals are illustrated and comments are made on their changes during the year. In adult males, the spermatogenesis commences in spring, after the change from winter torpidity to active life, and culminates towards the end of July and in August. During the winter months (December to April), the seminiferous epithelium of the tubules of testes is resting. On the...

Dr. P. S. Ashton has taken up an appointment as a lecturer in botany at the University of Aberdeen, Scotland, after the completion of his work in Sarawak in September 1966. A programme of cooperation has come into existence between the universities of Aberdeen and Kuala Lumpur, Malaya. Dr. Ashton’s teaching duties will leave him plenty of time for research and facilities will be cheated that he regularly can spend a period in the Malesian Archipelago for field work. Dr. L. J. Brass retired from the Archbold Expeditions and Museums in May 1966. He returned to Australia where he has been offered an honorary curatorship to the Herbarium of the North Queensland Naturalist’s Club at Cairns.

Significance of the clamp-connection in the Basidiomycetes
Provedor de dados: 16
Autores: Furtado, João S.
The cytogenetic phenomena affecting clamp-connection formation and the interpretation of this peculiar type of septum in the classification of the higher Basidiomycetes were reviewed from the literature and discussed. The cytogenetic data available are restricted to a small number of basidiomycetous species, but the formation of clamp-connection is included among the major phenomena whose genetic control is generalized for the Basidiomycetes. Clamp-connection formation in heterothallic species is controlled by the factors affecting sexuality. Simple septa appear in the hyphae of clamp-connection bearing species when (1) the simple septa result from independent nuclear division of the dikaryon, with or without subsequent hyphal growth of the newly recovered...

A revision of the specimens described by Sars, 1894, as Gammarus campylops Leach, 1814, proved that they did not belong to that species, nor to Gammarus ochlos Reid, 1945 (= G. sarsi Reid, 1943), as Reid believed. Reid’s species, of which also original specimens have been reexamined, is identical with Gammarus zaddachi Sexton, 1912. Sars’s material is redescribed here in detail, under the name of Gammarus inaequicauda Stock, 1966.

Some Anatomical, systematical and Geographical data on Neniinae (Gastropoda, Clausiliidae)
Provedor de dados: 16
Autores: Loosjes, F.A.; Loosjes-van Bemmel, A.C.W.
I. INTRODUCTION Up to the moment more than one hundred species and subspecies of Neniinae are known from Central and South America. They are incorporated into 22 genera and subgenera, almost exclusively based on characters of the shells. Only little is known of the anatomy of the animals (Binney, 1871; Binney &amp; Bland, 1871; Baker, 1961; Hesse, 1925; Scott, 1954; Loosjes, 1957; Pilsbry, 1926; Polinski, 1922; Zilch, 1953, 1959). These authors described the radula and/or the genital organs of one or several species. Thus from eleven species the radula has been described and from five the genital apparatus. By the courtesy of Prof. Dr. W. Weyrauch we were able to study the anatomical features of a relatively large number (38) of Peruvian and Argentine...

While in Suriname during June 1964, I had the opportunity of collecting a series of a species of Hyla that seems to be undescribed. It seems appropriate that this species be known as Hyla boesemani sp. nov. (fig. 1) Diagnosis. — A small Hyla with vomerine tooth patches close together or contiguous; with just a trace of web between the fingers; fourth toe webbed to the base of the penultimate phalanx; a small but well-developed patagium; a very distinct skin fold across chest. It has a dorsal pattern of scattered light spots, a distinct, narrow, postocular dark stripe, and lacks a pattern on the thigh although the latter has a small amount of uniformly distributed pigment present. This species is perhaps most easily confused with the members of the Hyla...

This paper forms a part of the general study of the Subtribe Paronychiinae undertaken by the author for his doctoral dissertation. The publication of the new taxa, in a separate form, has been necessitated by the fact that the Flora of Turkey, covering the Family Caryophyllaceae, is to be published in the near future, at any rate before the author can present a consolidated account of the results of his own study of the group. The present paper deals only with the diagnosis and description of the new taxa, presented in a rather conventional manner, and no attempt is made to go into details of the various morphological and taxonomic problems pertaining to the genus Paronychia as a whole. Such problems will, of course, be taken up in the general revision of...

Seismic reflection measurements with a pneumatic sound source in the Ría de Arosa (NW Spain)
Provedor de dados: 16
Autores: Hinz, K.; Pannekoek, A.J.
In 1968 continuous seismic profiles with a total length of 150 km were made in the Ría de Arosa (Galicia, NW Spain). They were executed by the Bundesanstalt für Bodenforschung (Hannover) with the assistance of two members of the Department of Geology of the University of Leiden (The Netherlands). The pneuflex (airgun) system used for profiling is described. The transformation of travel-time profiles into depth profiles was done automatically with the aid of a computer program. The profiles reveal the presence, below some 7—12 m of Holocene marine muds, of bedded deposits with a thickness of about 30 m (and in the outer part of the ria even more than 60 m), which are interpreted as being of fluvial origin. They are underlain by what is assumed to be...

The identity of Euthales filiformis de Vriese from Western Australia

Euthales filiformis de Vriese (7) was described from a specimen collected in Western Australia ‘in solo sublimoso fertili prope praedium rusticum Dom. Marell, York d. 30 m. Martii 1840. Herb. Preiss No. 1889.’ As appears from the original description de Vriese himself had already his doubts about its belonging to Euthales, a Goodeniaceous genus: ‘dichotoma, filiformis; foliis radicalibus squamaeformibus, caulibus ramisque aphyllis; calycibus 5-fidis, subaequalibus (Caetera non vidi). Habitus Junci bufonii, sed genus dubium.’ In a later publication of de Vriese (8) the calyx is said to be trifid, but this is obviously a printing error. It is a matter of course that Bentham (2), who had not seen the plant, was unable to recognize it from this very...

The materials, kindly supplied to me by Dr. A. J. M. Leeuwenberg and by Ir. F. Breteler, were collected in the form of seed-samples in the Ivory Coast and in Cameroun. The plants of 2 species originate from botanical gardens. Living material of all species (except for Strychnos lernata Gilg. ex Lwb.) is grown in the botanical garden of Wageningen (WAG). The determination of the chromosome numbers was based on the study of roottipmitoses. Roottips of the plants were fixed in...

The inland heath vegetations of the Netherlands consist of three main types: the dry heath complex, Calluna vulgaris dominant; the humid heath complex, Calluna and Erica tetralix co-dominant; and the wet heath complex, Erica tetralix dominant. Each of those complexes shows some variation in its floristic composition caused by ecological and geographical factors. The water and mineral nutrient content of the soil are the two ecological master factors.

In a previous palynological study in Cocoid palms the present authors (Punt and Wessels Boer, 1966) were able to demonstrate a rather strong but not absolute correlation between the pollen types and the staminate flower types within the genus Attalea in the broad sense. The existence of partly apparently primitive, partly very advanced flower types within the otherwise close related group of Geonomoid palms made it worthwhile to investigate the same feature in this group. The Geonomoid palms are usually considered to comprise 7-9 genera of monoecious Arecoid palms which share a large number of characteristics (Burret, 1930; Moore, 1966). The group is very obviously a most natural one. The generic distinctions are mainly based on the flower morphology,...

Some current trends in palynology
Provedor de dados: 16
Autores: Manten, A.A.
A number of modern developments in palynology are reviewed, with emphasis on those subjects which may be of interest and, possibly, also of practical value to geologists of various specializations. These include pollen preservation, the use of accumulation-rate diagrams as opposed to the classical pollen-percentage diagrams and the application of fluorescence microscopy. Marine palynology is discussed in a rather detailed fashion and its various prospects for stratigraphy, sedimentology and environmental geology are outlined. Some trends in pre-Quaternary palynology include new attempts at a palyno-stratigraphy of the Neogene, the many applications of palynological studies of salt deposits, the growing importance of palynology to palaeogeography,...

The compact key
Provedor de dados: 16
Autores: NN.
Here is given a sample of a new sort of identification key, recently developed by Dr. P. W. Leenhouts of the Rijksherbarium. Having to sort many specimens of Sapindaceae into genera, he became dissatisfied with the common dichotomous key, which too often does not work when the material is not complete. When he had extracted the existing descriptions, tabulated the characters, and written them up horizontally, with the names in code, he found not only that in a given space it contained far more information than does a dichotomous key, but also that it worked far better. He then proceeded to devise a synoptic key to the Malesian species of Santiria The numbering of the species is the same as that in the Flora Malesiana revision (I, 5: 229), namely: 1 =...

Vitrinellidae (Marine Mollusca Gastropoda) from Holocene deposits in Surinam (Dutch Guiana)
Provedor de dados: 16
Autores: Regteren Altena, C.O. van.
Five species of Vitrinellidae have been found in the Holocene shell ridges of Surinam. Of these, Vitrinella (Striovitrinella) cupidinensis,Cochliolepis surinamensis, and Solariorbis guianensis are new species, while Cyclostremiscus caraboboensis Weisbord is known from Pliocene beds in Venezuela and Teinostoma (Pseudorotella) schumoi Vanatta belongs to the Recent fauna of Guatemala. A paratype of Vitrinella cupidinensis spec. nov. was found on Olinda beach near Recife, Brazil, and clearly is a Recent shell. It seems possible, and even likely, that eventually all five species will appear to be still living in the same general region.

Provedor de dados: 16
Autores: Maguire, Bassett.
The precursor studies1) and floristic treatment of P.J. Eyma of the Guttiferae of Suriname2) exhibited a remarkably keen insight into the biology and taxonomy of this rather complicated family. Particularly this is true of the genus Clusia, which is the concern of this paper, and for which even yet the overall biology is indeed too little known. In the Flora of Surinam (1.c.) Eyma admitted eleven species. Now, as a result of more field activity from which much new material has been derived, there can be credited to Suriname fourteen species, of which three have been collected in that country subsequent to the studies of Eyma. Name changes are required for two species.

Remarks on the position, the delimitation and the subdivision of the Rubiaceae

Autores: Bremekamp, C.E.B.
It is often assumed that the delimitation and the subdivision of the various families which have been distinguished in the Angiosperms, do no longer offer serious difficulties. They would belong to those objects of study for which already long ago a fairly satisfactory solution was found. If we wish to be acquainted with this solution, the only thing we would have to do, would be to look up such works as Bentham and Hooker’s “Genera Plantarum” and Engler and Prantl’s “Natürliche Pflanzenfamilien”. Some improvements might still be desirable, but these would be of minor importance only. These assumptions, however, are to be regarded as dangerous illusions. That the very serious nature of the shortcomings found in the delimitation and subdivision of these...

The genus Lagenophora was first described by Cassini under the name Lagenifera (in Bull. Soc. Philomat. 12, 1816, 199) with the following diagnosis: ‘Ce genre, de la tribus des astérées, comprend le calendula magellanicá, Willd. et le bellis stipitata, Labill. Son principal caractère reside dans la cypsèle lagéniforme, comprimée, prolongée au sommet en un col qui ne porte point d’aigrette. Les fleurons sont mâles’. Two years later, in the same periodical (1818, p. 34) he changed the name Lagenifera without comment into Lagenophora, the latter being simply the latinized Greek equivalent of Lagenifera. Later authors have unanimously accepted the name Lagenophora, although Davis pointed out that Lagenifera has priority. Only recently Backer &amp; Bakhuizen...

A study of the genus Trychosis Foerster in Europe (Hymenoptera, Ichneumonidae, Cryptinae)
Provedor de dados: 16
Autores: Rossem, G. van.
INTRODUCTION This study was undertaken to prepare keys to the European species of the genus Trychosis Foerster. The older keys by Schmiedeknecht (1890 and 1904-1906), mostly based on Tschek's keys in his study of the genus Cryptus (1870b), do not lead to satisfactory results. This is due to the fact that several characters used by Tschek are not critical, while several of the species described by him have turned out to be identical with others. Nevertheless Tschek's pioneer work in this group deserves our admiration. When I had advanced somewhat with the interpretation of Tschek's type material, I became curious about the species described by some other authors, viz. Thunberg, Gravenhorst and Thomson. I had the opportunity to study some of their type...

Autores: Holttum, R.E.
A study of these three fern-genera has been undertaken for Flora Malesiana. Teratophyllum and Lomagramma have their main distribution in Malesia; Lomariopsis is pantropic. All three have a distribution extending to the Society and Austral Islands and to New Caledonia; all three are almost confined to the tropics, and all are found only in welldeveloped evergreen forest, so that in the Pacific they only occur on islands large enough to develop such forest. Only Teratophyllum occurs in Queensland. These ferns have a peculiar growth-habit in common. The plants have their main root-system in the ground, but climb to a considerable height up the trunks of trees, attaching themselves by roots which grow from the ventral surface of their climbing rhizomes.

Together with the class of the Schizomycetes (bacteria) the Cyanophyceae belong to the division of the Schizophyta which division differs from all other plant divisions by lacking a nucleus. However, the central part of their cells is a nuclear equivalent (Procaryota). This nucleoplasm or centroplasm or central body in the Cyanophycean cell has been studied profoundly these last fifteen years (Beck, Bowen, Cassel, Fuhs, Giesy, Herbst, Hutchinson, Jensen, Jost, Pankratz, Rabinovich, Sun and others) by means of the electron microscope. The resulting papers are mostly beautifully illustrated by electron micrographs.

Morphology of the androecium in Malvales
Provedor de dados: 16
Autores: Heel, W.A. van.
In order to test the applicability of the telome and the classic theories to the nature of stamens a study was made of flowers in Malvaceae, Bombacaceae, Sterculiaceae, Tiliaceae, and Elaeocarpaceae with respect to their ultimate form, their development, and the vascular course of their androecia. The customary dissecting, clearing, and microtomy techniques were used. A chapter on the interpretation of the vascular bundle course in floral morphology has been added. In each flower the stamens are considered to be arranged in five groups, which may be fused more or less laterally. The groups have a three-trace vascular system the laterals of which may be commissural. Only a few Tiliaceae have ten groups. Whereas in most Tiliaceae and Elaeocarpaceae the...

From July 1958 to May 1959 an investigation was carried out of the relation between physiognomic characteristics of the vegetation and the habitat on some savannas in the vicinity of Zanderij, Surinam. Root systems, structure, periodicity and characteristics of the leaves were considered, both of the species separately and of the vegetation types. Nine vegetation types were studied which were described floristically by Heyligers (1963) and Van Donselaar (1965). The vegetation types differ in structure. The available types of structure are: low and sparse vegetation of tussocks of grasses and sedges; dense vegetation of both low and high tussocks of grasses and sedges; high and closed vegetation of tussocks of grasses and sedges, with or without a...

The subject of this study is the largest of the ‘classical’ rias in W. Galicia, the Ría de Arosa (length 25 km, depths of over 65 m). The bottom of the ria displays a complex topography. The wide variety of the surrounding rock types results in the supply of heavy minerals and clay minerals of a variegated composition. The different types of sediment occurring in the bay are described. The results of various laboratory analyses of some 400 grab samples form the basis of the discussions, but punch-core and boring samples were also studied. The present sedimentary processes are inferred from data obtained from textural and petrographical analyses in combination with the oceanographical and biological characteristics of the ria.

The structure of the ovipositing organs as a tribal character in the Indo-Australian Sycophagine Torymidae (Hymenoptera, Chalcidoidea)
Provedor de dados: 16
Autores: Wiebes, J.T.
Landmarks on the distal segments of the female Chalcidoid gaster are the spiracular peritremata of the eighth urotergite, and the pygostyli of the ninth. The eighth and ninth sterna bear the first and second valvulae, which form the effective ovipositor and its sheath, respectively. The ninth moreover bears the third valvulae, commonly called the valves of the ovipositor. Most Chalcidoid Hymenoptera of the family Torymidae have a long ovipositor, in some instances several times as long as the body. Comparative study of fig wasps of the subfamily Sycophaginae shows that the great length of the ovipositing organs in different groups, may have been acquired by different means. The characters of these structures of the females appear to be correlated with...

Ever since the pioneer researches of Miss Polak on Malesian peat before the second world war, it has been clear that an immense amount of information of great botanical interest was waiting to be discovered in the peat, coal, clay and shale deposits, which are so widespread in the sedimentary record of this area. It was an economic motive which in 1953 led the Brunei Shell Petroleum Cy. in Brunei (NW. Borneo) to start palynological research. The aim was to distinguish palynological zones in the thick Tertiary oil bearing sediments which were difficult to correlate otherwise. During the course of this work many data of botanical interest came to light and short notes on these results have been published already.

During a study of the Potamonidae in the collections of the Museum of Biology of the Central University of Venezuela, Caracas, three undescribed species of Pseudothelphusa were found. One of these was discovered in material from the Venezuelan Guiana. While the other two probably came from the same area, the labels in the corresponding jars were only marked "Venezuela". The three species are closely related to each other as is suggested by the close similarity in the shape of the first pleopod of the male in each. The lateral teeth of the carapace are larger in these species than in the others described from northern Venezuela (Rodriguez, 1966).

The geomorphology of western Galicia is reconsidered in the light of Nonn's monograph (1966), and an envelope map of the relief, as defined by Stearns (1967) and Pannekoek (1967), and an interpretation of the latter are also presented. The envelope map shows more clearly than an ordinary contour map that the major relief features are not controlled by the lineations of the Hercynian basement but by late- or post-Hercynian faults, some of which may have been reactivated in Tertiary times. Concerning the geomorphological evolution, the author agrees with most of Nonn's conclusions, although there is some divergence on minor points. The isolated mountain massifs, capped by remnants of older pediplains, already existed in Upper Miocene times. The depressions...

Notes on chameleons III. The chameleons of southern Arabia
Provedor de dados: 16
Autores: Hillenius, D.
Three chameleons have been described from southern Arabia: Chamaeleo calyptratus Duméril &amp; Duméril, 1851; Chamaeleo calcarifer Peters, 1871 and Chamaeleo arabicus (Matschie, 1893). Chamaeleo arabicus is clearly connected with typical Chamaeleo chamaeleon by intermediate forms: Chamaeleo chamaeleon orientalis Parker, 1938 and Chamaeleo chamaeteon musae Steindachner, 1900 and it thus may be regarded a subspecies of Chamaeleo chamaeleon itself. Chamaeleo calyptratus, though in many respects clearly related to the group around Ch. chamaeleon, shows so many differences, whereas the range lies in the midst of the range of Ch. chamaeleon arabicus, that it is considered here as a true species. Chamaeleo calcarifer possesses a mixture of characters of Ch....

A re-examination of the Kedung Brubus mandible

Autores: Tobias, P.V.
During a visit to the Rijksmuseum van Natuurlijke Historie in Leiden in July 1964, Dr D. A. Hooijer kindly allowed me to re-examine the mandibular fragment which had been discovered by Eugène Dubois on 24 November 1890 at Kedung Brubus, a fossil locality in the Kendeng Beds in Central Java (Dubois, 1891a, 1891b, 1924a, 1924b). As a result of a possibly important new point which emerged during my examination of the specimen, Dr Hooijer urged me to place my observations and their implications on record. It is the purpose of this short paper to do so.  BRIEF HISTORICAL SYNOPSIS In his original two notes of 1891, Dubois clearly recognized the fragment as belonging to "Homo spec. indet." He drew attention to the poor chin development and the curious flattening...

Op de 28ste september van het jaar 1859 sprak de toen juist aan deze Universiteit benoemde hoogleraar Miquel zijn ‘inwijdingsrede’ uit „over het tegenwoordig standpunt der plantenkunde en haar verband met andere wetenschappen”. Miquel was op het moment van het uitspreken van zijn rede een algemeen bekend botanicus, maar toch wel in de eerste plaats een plantensystematicus, en zijn rede was daarom in hoofdzaak een bespiegeling over de positie van de plantensystematiek te midden van verwante disciplines. Zij bevatte bovendien een aantal min of meer theoretische beschouwingen over de grondslagen van de plantensystematiek. Nu is het jaar 1859 niet de geschiedenis van de biologie ingegaan als het jaar van Miquel, maar zoals u allen uiteraard bekend is, als dat...

This is the second book by professor Meeuse on the phylogenetic morphology of the reproductive organs of the Higher Cormophytes. It is superior to the first *, not only in the get-up, but also in providing some more information on the principles of the author. The core is disclosed in: ‘all we can do is to postulate a phylogenetic genealogy, using all available (palaeobotanical) evidence, and build up the evolutionary sequences in the phylogeny of the organs, the semophyleses, along our framework’. And: ‘Typology is to be checked by fossil data’. We meet the method of the New Morphology, as it was started by H. Hamshaw Thomas. The phylogenetic line depicted leads from the Progymnospermopsida Beck through Cycadopsid Gymnosperms towards Angiosperms. It is...

Sagittaria sagittifolia in Zeeuws-Vlaanderen. In de „Lijst van openbare en bedektbloeiende vaatplanten in Zeeland” door A. WALRAVEN (in Ned. Kruidk. Arch. ser. 2, deel 3, 1878, p. 134) wordt deze zoutmijdende soort opgegeven voor Oost Zeeuws-Vlaanderen. Hoewel ik vele jaren in de ook daar spaarzame, zoete wateren heb gezocht, heb ik de soort noch daar, noch ergens anders in Zeeland, ooit teruggevonden. Bijzonder verheugend was het daarom, dat in 1966 tijdens de excursie van de Commissie voor het Floristisch Onderzoek van Nederland pijlkruid bleek te groeien in een slechts enkele jaren geleden gegraven brede afwateringssloot in het ruilverkavelingsgebied ten zuidwesten van de Everdamse dijk tussen Zuiddorpe en Zwartenhoek.

Einige bemerkungen über die pollenführung der Braunkohlengrube “Maria Theresia”, Herzogenrath

Autores: Meulenkamp, J.E.
The pollenflora of the browncoal mined in the quarry “Maria Theresia”, Herzogenrath, Western Germany has been investigated. Samples were taken along a section of 12.50 meters at intervals of 50 centimeters. Identifications were made on the basis of form-genera and form-species; this working method gives a broad information on pollen types, but does not relate the fossil pollen types primarily to recent plant taxa. Pollen types which are considered to belong to Betulaceae/Myricaceae make up the biggest part of the pollen assemblages. The construction of a “Composite diagram” for Betulaceae/Myricaceae proved to be useful and might give a better idea on paleoecologic conditions. The stratigraphic position of the browncoal examined is thought to be Lower...

Wood anatomy of the genus Euplassa and its relation to other Proteaceae of the Guianas and Brazil
Provedor de dados: 16
Autores: Mennega, Alberta M.W.
Three genera of the Proteaceae belonging to the tribe Grevilleeae occur in the Guianas and Brazil: Roupala, Panopsis, and Euplassa. The microscopical wood structure of one of these genera, Euplassa, has not been described before. Anatomically it proves to be nearly identical with Panopsis which it also resembles in general properties. Roupala differs in several respects. Within the genera differences are not fundamental and chiefly a matter of numbers and dimensions. A key to the genera is given. The relation of these three genera with the two other members of the tribe in South America, Orites and Gevuina, is discussed.

Recent pollen spectra from the deciduous and coniferous-deciduous forests of Northeastern Minnesota: a study in pollen dispersal
Provedor de dados: 16
Autores: Janssen, C.R.
Pollen samples were taken along nine transects across local vegetational belts bordering bogs or ponds in overall deciduous and coniferous-deciduous forest regions. Three types of pollen rain are distinguished: local, extralocal, and regional. Local pollen rain is derived from plants that grow at or very close to the sampling point. High local values are common in all sorts of vegetation types: lakes, bogs, marshes, and forests. Extralocal pollen rain is derived largely from trees that grow on the slopes and upland adjacent to the sampling site, but not extensively over larger areas. When excluded from the pollen sum along with the local types, its curves increase slightly, but noticeably, along the transect as the source of dispersal is approached. The...

The Hibernation of the oak Mildew

The oak mildew invaded Western Europa in the years 1908 and 1909. Since then this parasite, Microsphaera alphitoides Griff. &amp; Maubl. (syn. M. quercina (Schw.) Burr.) has occurred regularly in the Netherlands on oak seedlings and oak coppice, mainly Quercus pedunculata Ehr. (syn. Q. robur L. ). After the appearance of the fungus its identity and also its mode of hibernation has been amply discussed. Perithecia with ascospores were discovered by Arnaud and Foëx (1912) in France. In the Netherlands perithecia were only occasionally observed, as their occurrence seems to depend on weather conditions during the summer months (Hartsuyker, 1939). Besides ascospores, if present, chlamydospores on old infected leaves described by Ferraris (1909) might be a...

Carbonization measurements of pollen-grains and spores and their application
Provedor de dados: 16
Autores: Gutjahr, C.C.M.
This study presents the equipment and technique used in the author’s palynological carbonization studies. The equipment consists mainly of modified Zeiss microphotographie equipment. A photoelectric cell fitted with a field restrictor is used to measure the light absorption of a spore or pollen type. The light-absorption value is considered to be a measure of carbonization, and values of a standard spore or pollen type are used to construct a carbonization line for an individual well. Isocarbonization lines can be constructed in sections to show local or regional carbonization. Maps, block diagrams, panel diagrams, etc., can be constructed with either isocarbonization or carbonization contours. Carbonization is a low-grade metamorphic process; an...

About 1919 cuttings of the North-American poison-ivy, Rhus radicans L., were planted to consolidate a dike between two lakes in the southwestern part of Friesland, Morra and Vogelhoek. The species has completely established itself there, and at present as a real liana, it covers nearly the whole dike and its willow-vegetation over a distance of about 500 m. To some extent the poisonous plant means a danger to the inhabitants of the neighbouring villages, especially to the children, who go there swimming and picking blackberries. Some cases of an obstinate eczema have already occurred. Parents warn their children against the “poisonous trees” of Vogelhoek!

Note on Leptomicrurus collaris (Schlegel) (Reptilia, Serpentes)

An attempt to prepare a survey of the poisonous snakes of Surinam led to the discovery of a specimen of the very rare coral snake Leptomicrurus collaris (Schlegel) in the Zoological Museum, Amsterdam, and to tracing another specimen in the Staatliche Museum für Naturkunde, Ludwigsburg (Stuttgart Museum). For long years the species was known under the name of Hemibungarus collaris (Schlegel), and as such it was supposed to occur in the Philippine Islands. The history of Elaps collaris Schlegel, 1837, was briefly discussed by Schmidt (1937), who transferred the species (together with Elaps narduccii Jan, 1863) to a separate genus Leptomicrurus Schmidt, 1937.

The early evolution of the Archegoniatae: a re-appraisal
Provedor de dados: 16
Autores: Meeuse, A.D.J.
After a re-appraisal of the alternative hypotheses concerning the origin and the early evolution of the archegoniate land plants, the postulation of a thalassiophytic group of precursors with free isomorphic alternating generations by Church, Zimmermann, and several others is rejected. Several versions and modifications of this ‘homologous’ theory, such as Fritsch’s suggestion of diminutive filamentous algal being the progenitors of the vascular plants and Jeffrey’s idea of an advent of partly emerged (aerial) sporangiate extensions of an aquatic sporophyte, are equally untenable. In the present author’s opinion the old and reputedly almost obsolete ‘antithetic’ theory is much more compatible with the relevant evidence, provided this hypothesis is more...

A new subspecies of anthreptes malacensis (Scopoli) from the Soela Islands (Aves, Nectariniidae)
Provedor de dados: 16
Autores: Mees, G.F.
For over a century the sunbird Anthreptes malacensis has been known to occur on the Soela Islands where it reaches the eastern limit of its distribution, and when Shelley (1877) named Anthreptes celebensis, now known as Anthreptes malacensis celebensis, he included the Soela Islands in its range. In subsequent years apparently only Hartert (1898) has in the briefest possible way discussed specimens from the Soela Islands, stating that they were: "quite like Celebes specimens". At this the matter has rested with the result that in the latest list (van Bemmel, 1948) the Soela Islands are still included in the range of Anthreptes malacensis celebensis. When Stresemann (1932) restricted, in the Celebes, the range of A. m. celebensis to the southern peninsula,...

The Old World species of Prunus subg. Laurocerasus including those formerly referred to Pygeum
Provedor de dados: 16
Autores: Kalkman, C.
The present study was originally intended to be a taxonomic revision of the genus Pygeum (Rosaceae). This genus was always considered to be closely related to, but different from Prunus. However, the delimitation of Pygeum against Prunus subg. Laurocerasus appeared to be extremely difficult, and after careful consideration I was compelled to reduce Pygeum to Prunus. This reduction is the most radical taxonomic novelty in the present paper (Chapter 3). A new subdivision of subg. Laurocerasus, now enriched with Pygeum, was inevitable. Three sections are distinguished here, viz.: a. sect. Laurocerasus, containing the Eurasian and tropical Asiatic species which were already considered by older authors to belong to the (sub)genus Laurocerasus, and moreover the...

The variability of the principal differentiating characters of Spergularia marginata and S. salina was studied by means of analyses of population samples. Both species proved to be sharply definable in the Netherlands; no intermediates were found. In certain habitats a form of S. marginata occurs with exclusively unwinged seeds. It seems that S. salina, on the other hand, has a form with broadly winged seeds only. So far it was found in but a single Dutch station.

INTRODUCTION During his investigation of the amphipod fauna of the sandy beaches of the Netherlands, Mr. W. J. M. Vader, formerly of this institute, met with two species of Eurydice Leach, 1815. Besides the common Eurydice pulchra Leach, 1815, he found a second species in smaller numbers. Because Giordani Soika (1955) as well as Renaud-Debyser &amp; Salvat (1963) recorded Eurydice affinis Hansen, 1905, and E. pulchra from comparable beaches in northern France, Mr. Vader asked Dr. B. Salvat for some specimens of the former species for comparison. When these specimens arrived, Mr. Vader had left our laboratory. He was kind enough to entrust me with the further study of the Eurydice problem, for which I am most indebted to him. Further I want to thank Dr. L....

Isolation of living Algae growing in the shells of Molluscs and Barnacles with EDTA (ethylenediaminetetraacetic acid)
Provedor de dados: 16
Autores: Prud’homme van Reine, W.F.; Hoek, C. van den.
Several decalcifying mixtures or aqueous solutions of inorganic or organic acids are generally used for releasing algae growing in the shells of molluscs and barnacles, for instance dilute hydrochloric, nitric, citric, or acetic acid (4), a mixture of nitric acid, chromic acid and alcolhol (1), nitric acid and alcohol (9), chlorine dioxide and acetic acid (diaphanol) (3, 6, 11, 12), and formic acid and formiate (8). For a review see (7). Such mixtures or solutions generate carbondioxide bubbles that more or less disorganise the histological structure of the thallus. They also hydrolyse cell-contents and cell-wall material. Diaphanol and formiate appeared to be relatively useful for conserving the histological structure of the thalli. Recently (5, 10, 13)...

Notes on land slugs : 11. Arionidae, Milacidae and Limacidae from South Africa (Mollusca, Gastropoda Pulmonata)
Provedor de dados: 16
Autores: Regteren Altena, C.O. van.
New records of Arion intermedius Norm. are given. All known data on the genus Oopelta Mörch have been compiled and supplemented by new observations, mainly on O. nigropunctata Mörch and O. capensis Poll. Of the former species the type specimens were examined and the external variation and anatomy were studied. A fine series of O. capensis, with notes on the living animals by Mr. van Bruggen, enabled the author to study that species in detail. The affinities of Oopelta are discussed and it is concluded that the genus should be maintained in a subfamily of its own, Oopeltinae Cockerell, 1891, in the Arionidae. It seems unlikely that the type locality of O. nigropunctata on the Gold Coast near Accra (Ghana) is autochthonous. The distributional area of Oopelta...

Ruthiella, a new generic name for Phyllocharis Diels, 1917, non Fée, 1824 (Campanulaceae)
Provedor de dados: 16
Autores: Steenis, C.G.G.J. van.
In Taxon 10 (1961) 261, a proposal was published to conserve the generic name of the Papuan genus Phyllocharis Diels, 1917, against Phyllocharis Fée, Essai Crypt. (1824) lix, xciv, t. ii, fig. 3 &amp; 7, a name for a genus of Lichens. Fée was the only author who ever recognized it; it was reduced by Montagne about 15 years later and this reduction was accepted by all later lichenologists. As a matter of fact an experienced lichenologist was one of the three botanists who endorsed the proposal by undersigning it. Therefore, no harm would have come from accepting the proposal and this would have been distinctly useful for stabilizing the generic name Phyllocharis in the Campanulaceae, not only for the few botanists working in New Guinea, but for all...

The structural history of the Vall Ferrera area, the transition zone between the Aston Massif and the Salat-Pallaresa anticlinorium (Central Pyrenees, France, Spain)
Provedor de dados: 16
Autores: Oele, Jan Adriaan.
Cambro-Ordovician clastic sediments varying in composition from microconglomerates to slates occur. A more precise stratigraphic assignment is impossible, because of the lack of fossils and traceable stratigraphic horizons. The Cambro-Ordovician rocks have undergone four Hercynian deformation phases. Each phase was accompanied by the formation of cleavages (slaty, fracture or crenulation cleavage). In the Vail Ferrera area these four deformation phases are well developed. Their relative age relationships were known from other parts of the Central Pyrenees and could be established in many outcrops. The first deformation, accompanied by a regional synkinematic metamorphism and caused by a N-S compression, divided the orogene into (1) the infrastructure...

A review of the Herbaceous species of Polygala in Malesia (Polygalaceae)
Provedor de dados: 16
Autores: Adema, F.
The subdivision of the genus as proposed by Chodat in his Monograph of the family, seventy five years ago, needs emendation. First, one of his sections, Semeiocardium (Zoll.) Hassk. must be completely reconstructed. It is typified by a singular genus Semeiocardium occurring in Madura and Kangean Is. (off NE. Java) which was described by Zollinger as a Balsaminacea, but included by Hasskarl in the Polygalaceae, in which he was followed by Chodat. Backer has indubitably shown that Zollinger’s opinion was correct and that it represents a remarkable, endemic genus of the Balsaminaceae (Gard. Bull. Str. Settl. 9, 1935, 70). For the other species included in this section a new section must be accepted which I have named Pseudosemeiocardium. Furthermore, through...

The Lesser Antillean Ameiva (Sauria, Teiidae) Re-evaluation, zoogeography and the effects of predation
Provedor de dados: 16
Autores: Baskin, Jonathan N.; Williams, Ernest E.
The Ameiva of the Lesser Antilles present an interesting case of isolated populations of related animals on a chain of islands that differ in size and proximity among themselves but form a geographic group. The situation is made still more interesting by the fact that at times in the Pleistocene the sea was 100 fathoms or more lower, and certain of the islands were then connected by land. The discovery of a new species of Ameiva on Maria Island off the south coast of St. Lucia and the attempt to identify and place taxonomically the three specimens first sent to us by GARTH UNDERWOOD provided the stimulus to a brief re-survey of this neglected but, from a zoogeographic and evolutionary point of view, extremely interesting set of forms.

Provedor de dados: 16
Autores: Haas-Niekerk, T. de.
The species of the genus Sphacelaria Lyngb. that occur in the Netherlands have been investigated. These species are: S. plumigera Holmes, S. radicans (Dillw.) Ag., S. fusca (Huds.) Ag. It is suggested that S. furcigera and S. saxatilis should be regarded as synonyms of S. fusca. It was found that S. fusca also forms bifurcate propagulae in contrast to reports in the literature. Cultures were grown of S. plumigera, S. fusca, S. britannica, and S. radicans. The cultures of S. fusca, S. britannica, and S. radicans exhibited very feebly fixed polarity in contrast to the cultures of S. plumigera. S. cirrosa and S. fusca are considered to be two different species.

Since the last Bulletin was published we have to regret the loss of four persons who were supporters of Flora Malesiana or collaborated with it in some way or other. Mr. P. Groenhart started his career in Java as a botany teacher in the Agriculture School at Malang. He was keenly interested in plants and became gradually specialized in lichens which are, particularly in the tropics, a fascinating group, under-collected and inadequately known. Though an amateur, he gradually elevated his work to a true scientific level and was granted extended leave for this work in the early thirties which he spent at Utrecht University, Holland. From this emanated an enumeration of Javanese lichens and several other papers. Since then he gradually accumulated a large...

Autores: Vecht, J. van der.
In 1913 A. von Schulthess published under the title "Parapolybia Saussure" a revision of the Old World social wasps which in general appearance are similar to certain species of the American genus Polybia. Only a few months later R. du Buysson described some new species of "Polybia" from Asia and created a new genus Polybioides for one African and two Oriental species. Apart from the treatment of two African species of Polybioides in Bequaert's excellent work on the Vespidae of the Belgian Congo (1918; see also Bequaert, 1922) this group of wasps has since then received little attention. A detailed study of the Oriental wasps which at different times have been described or recorded as Polybia has led me to the conclusion that many of these belong to the...

Autores: Doesburg , P.H. van.
This paper is intended as the first of a series concerning the Surinam heteropterous fauna. Although our knowledge of these insects in Suriname is still very incomplete, a survey given in this phase of investigations may well have its justifications. In the first place, it gives us an idea of what is really known about this subject at present, and in the second place, it will perhaps encourage further investigations. In Suriname there is a great need for compilations which are also of use to the biologist whose work is of a more practical nature. Much attention is therefore given here to the diagnostic characters, and keys are added to identify the species. As literature is difficult to obtain in the Guyanas, I have given a more detailed account of every...

Three groups of features have been investigated by these methods. (a) General structure of regoliths. — They consist of a saprolite, mostly covered by colluvium. The latter can be distinguished from the saprolite by field methods, heavy mineral content and fabric analyses. The saprolites generally display spheroidal weathering.

In a comparative morphological investigation of all groups of mites, a detailed study of the interesting Opilioacarida must be of primary importance. Regarded as partly primitive and isolated, they present on the one hand an important series of characters in common with Anactinotrichida, on the other a somewhat shorter list of characters found also in Actinotrichida. A revaluation of these relationships appeared at this moment highly desirable. According to our present knowledge, Opilioacarida are rare, and the area of distribution is discontinuous.

The University herbarium of Utrecht dates traditionally from the year 1816 when a collection of about 3000 plants was bought from the professor of botany M. van Geuns (1735-1817). It is possible that other collections of dried plants were already owned by the University or at any rate by the botanic garden, before that time, but nothing is known about this. The small van Geuns herbarium, which contained collections made by J. D. Hahn, M. W. Schwencke and S.

The ratio of the number of dermal scale rows or annuli to the number of vertebrae has, therefore, been considered to be of fundamental importance in squamate classification (Stehli, 1910; Camp, 1923). Yet the difficulty of determining it has fostered the presentation of hypotheses based on relatively few total counts; some such hypotheses have relied upon comparisons made by dissection along limited portions of the trunk. The general implication communicated by the many statements in the literature has been that the ratios are constant at the generic or familial level, that the ratios ordinarily...

Geburtsvorgang bei Myotis myotis (Borkhausen, 1797) und anschliessendes Verhalten von Mutter und Jungem
Provedor de dados: 16
Autores: Kolb, Anton.
1. Bei der Geburt behalten die Weibchen von Myotis myotis und Eptesicus serotinus die typische Hängelage der Fledermäuse, den Kopf nach unten, bei. Sie heften sich jedoch auch mit den Krallen an der Unterlage fest, wodurch der Körper ggf. die Schräglage des Daches bekommt. Hierbei krümmen sie den Schwanz bogenförmig. 2. Das ausgestoßene Junge klettert zwischen dem Körper der Mutter und der Unterlage am Körper derselben zur Brustzitze und saugt sich fest. 3. Es wird von der Mutter eifrig beleckt. Durch seitliches Hängen des Hinterteiles seines Körpers reißt das Junge die Nabelschnur ab, wozu oft längere Zeit und heftiges Zerren notwendig ist. 4. Die vertrocknete Nabelschnur reißt an der Placenta ab. Diese wird kurz darauf ausgestoßen und von der Mutter...

Flavonols, leuco-anthocyanins, cinnamic acids, and alkaloids in dried leaves of some Asiatic and Malesian Simaroubaceae
Provedor de dados: 16
Autores: Nooteboom, H.P.
Herbarium specimens of 13 species of the Simaroubaceae were investigated on phenolic compounds present in their hydrolised leaf extracts and on the presence of alkaloids (table 2). Leucoanthocyanins, myricetin, gallic acid, ellagic acid, as well as alkaloids were demonstrated to occur rather frequently in this family. The relationships between the Simaroubaceae and Rutaceae and the position of the genera Irvingia and Suriana are briefly discussed: the Simaroubaceae and Rutaceae seem to be closely related not only morphologically but also biochemically. Irvingia seems to fit rather well in the Simaroubaceae (except for the assumed lack of bitter principles). Suriana deviates much more from all other species investigated. This stimulates further research to...

Coastal sediments of the southeastern shores of the Ría de Arosa (Galicia, NW Spain)
Provedor de dados: 16
Autores: Jong, J.D. de; Poortman, H.H.
The beaches of the southeastern shore of the Ría de Arosa are in general small and enclosed between rocky capes; especially those along the inner ria are not subjected to strong wave action. Nonetheless, the beach sands are often coarse-grained, being partially derived from the coarse-grained intrusive granites exposed in low cliffs along the major part of the shore. Generally, the sands along the low-water mark are finer than the better-sorted sands along the high-water mark, since the backwash is not able to transport the coarse grains. In some cases, however, granules derived from weathering granite are left behind at the low-water mark because the waves are too weak to carry them higher up on the beach. In protected embayments tidal flats originated...

Check list of European Hymenomycetous Heterobasidiae [Cont’d]
Provedor de dados: 16
Autores: Donk, M.A.
(62). In some respects Tremella encephala is even more variable than other species of the genus, for instance, as to colour, there are at least three principal shades. First, hyaline-whitish, the white colour being mainly due to the white kernel that shows through. It was this condition, I believe, that received the name Tremella alabastrina. A delicate flesh colour is very common. Neuhoff (1936b: 23) has suggested that Tremella fragiformis Pers. (which Persoon called ‘ruber’) was annotated by its German collector as stawberry (fraise) coloured and that Persoon misunderstood the information: “in der deutschen Tuchindustrie bedeutet fräsfarben ein milchiges Fleischrosa, das dem Farbton der T. encephala vollkommen entspricht.” It may be pointed out that when...

Autores: Hazlett, Brian A.
1. The social behavior patterns of twelve species of hermit crabs found in the waters around Curaçao, N.A. are described. All species showed marked similarity in their aggressive displays, the most common of which are movements of the appendages, called here the ambulatory raise and cheliped extension. 2. Model presentation experiments proved that these positions are effective visual stimuli. These tests also showed that the white tips of the ambulatories of Clibanarius tricolor are aggressive stimuli. 3. Pagurid crabs showed a dislodging-shaking behavior pattern when crawled upon by other individuals. Experiments were carried out to determine the relationship between stimulus weight and the size of a crab showing this pattern. 4. Measurement of laboratory...

Autores: Doing, H.
This paper is a contribution to a discussion among Dutch phytosociologists on the concept of “chief formation”, introduced by the author in former publications as a unit in the Braun-Blanquet vegetation system. It is contended that structure should play a major role mainly in the construction of the higher units of classification, floristics in the units of medium rank and species dominance in the lower units. The way in which these criteria can be applied in relation to each other is discussed and demonstrated on some examples of Australian and European vegetation. Special attention is given to the evaluation of dwarf shrub communities, tree savannas and tree and shrub deserts.

Water-Striders of the American Genus Trochopus
Provedor de dados: 16
Autores: Drake, Carl J.; Doesburg , P.H. van.
In April 1898 the veliid genus Trochopus Carpenter was erected to hold a new halophilous water-strider from Jamaica, described as marinus. The specimens were netted in numbers on standing salt waters beneath mangrove trees in swamps near the head of Kingston Harbour. In August of the same year CHAMPION described the second member of the genus, Trochopus salinus, collected in the mangrove swamps of the Pearl Islands, Gulf of Panama. Subsequently, KIRKALDY (1900) wrongly considered the genus Trochopus to be a synonym of Rhagovelia Mayr (1865), but correctly treated the trivial name marinus as a synonym of Rhagovelia plumbea Uhler. This generic synonymy was largely accepted until CHINA &amp; USINGER (1949) took Trochopus out of synonymy and restored it to its...

Autores: Rollins, Reed C.
Among the endemic and sometimes localized genera of the Cruciferae occurring in South America, Mathewsia stands apart as an element of the distinctive desert flora of southwestern Peru and western Chile. As far as present records show, the genus is confined to a relatively narrow strip wholly west of the main Cordillera, not far from the Pacific Ocean. Some species are confined to washes or small arroyos known as quebrades. Others occur as part of the lomas vegetation of western Peru. Populations of the same species occupying different quebradas often differ from each other to a limited degree and in many instances probably little or no gene exchange occurs between them. The intervening dry areas, separating one quebrada from another, are completely...

The Phytoseiidae have diverse habits. Some are apparently obligate predators, preying on other mites or on insects, others are facultative predators feeding on fungus hyphae, pollen, or plant sap when no prey is at hand (CHANT 1959a), and one species, Anthoseius hebetis DE LEON (1959b), is found only in the flowers of Heliotropium parviflorum where it probably feeds exclusively on pollen. Although phytoseiids are common in British Guyana there are no records of the occurrence of any species in that country. Through the kind invitation of Dr J. M. CHERRETT, a member of the University College of North Wales Guiana Expedition 1963 (OGDEN, 1964), I spent 13 days (22 Oct.—3 Nov. 1963) collecting mites in the Nature Reserve, near the Expedition’s Headquarters...

Paraphelaria, a new genus of Auriculariaceae (Basidiomycetes)
Provedor de dados: 16
Autores: Corner, E.J.H.
Recent collections from the Solomon Islands show that Aphelaria amboinensis (Lev.) Corner is an auriculariaceous fungus of coriaceous consistency, devoid of hymenium, but with the basidia immersed longitudinally in the superficial tissue. Re-named Paraphelaria ambonensis (Lév.) nov. gen., comb, nov., it is a parallel both to Aphelaria and to Tremellodendron.

Autores: Vervoort, W.; Ramirez, F.
INTRODUCTION The discovery of a new species of Hemicyclops, found pelagically in Argentine coastal waters, has made it necessary for us to summarize the descriptions of the species of Hemicyclops Boeck, 1872. In the course of our investigation, the results of which are laid down is this paper, it became necessary to construct a new key for the identification of the genera of Clausidiidae, which will be presented below. We have thought it advisable to state very briefly the position of the genera, basing ourselves mainly on the recent review of this family by Bocquet &amp; Stock (1957). We refrain, at the present stage, from presenting diagnoses of all genera. Many species are commensals or parasites of Invertebrates and the number of known species has...

Late Quaternary vegetation and glacial history in the St. Lawrence Lowlands, Canada

Autores: Lasalle, Pierre.
This paper presents data of various kinds concerning the Quaternary geology of the St. Lawrence Lowlands: pollen diagrams, C14 dates, and diatom floras. These data show that the highest parts of the St. Lawrence Lowlands were already deglaciated more than 12,000 years ago, as appears from the existence of glacial lakes around some of the Monteregian Hills. The collected evidence seems to confirm the data concerning the age of the Champlain Sea: it lasted from approximately 11,400 years B.P. to somewhat before 9,500 years B.P. The data supply also evidence for a lowering of sea level during the Champlain Sea episode, related to the St. Narcisse readvance, followed by a sea level rise (indicated by deeper water) after the retreat of the St. Narcisse ice.

Autores: Schultes, Richard Evans.
During the first fifteen years of the present century, the production of rubber from wild trees was a thriving, though nefarious, industry in the northwestern part of the Amazon Valley. The heaviest concentration of this primitive forest industry — and the most widely notorious — was centered in the area drained by the Ríos Karaparaná and Igaraparaná, northern tributaries of the Río Putumayo, lying between the Ríos Putumayo and Caquetá (Map 1). In this hey day of rubber production, the area was claimed by both Colombia and Peru, but the Peruvians actually occupied and exploited it. As a result of the war between Colombia and Peru in the early 1930’s, the boundaries have been set with the Río Putumayo as the frontier. Colombia is now in possession of the...

The botanical control of nature reserves based on structure ecology In contrast with previous ideas the human control of nature reserves is nowadays seen as indispensable for the preservation of variety-in space and stability-in-time. Botanical control of nature reserves has for its object the conservation of their various plant communities against alterations coming from the inside and the outside. A second purpose is the enlarging of their internal spatial variety, for the more variety-in-space is present the more varietyin-time can be counteracted. In both cases the cybernetical term “regulation amplifying” is an adequate expression for our activities.

Cultural evidence for the morphologic plasticity of Entophysalis deusta (Meneghini) Drouet and Daily (Chroococcales, Cyanophyceae)
Provedor de dados: 16
Autores: Prud’homme van Reine, W.F.; Hoek, C. van den.
Cultural experiments with Entophysalis deusta support Drouet and Daily’s concept of this species as a morphologically highly plastic taxon, showing forms traditionally identified as Entophysalis granulosa, Gloeocapsa crepidinum, Pleurocapsa fuliginosa, and Hyella caespitosa. These results are in accordance with observations on populations forming part of the ‘black zone’ of the upper intertidal belt. It is shown that Drouet and Daily’s taxonomic principles, leading to a broad and more natural concept of this species, are sounder than those underlying Geitler’s Cyanophyceae in which several entities included by them in Entophysalis deusta are treated as species.

A study of the beaches on the NW shores of the Ría de Arosa was made with respect to shape and structure of the beaches, grain-size distributions, heavy mineral associations, and relations of the heavy minerals to the bedrock of the hinterland. Most of these numerous small beaches are situated in inlets determined by the occurrence of relatively weak bedrock (mostly schists). Grain-size generally fall in fractions &gt; 50 µ, and some beaches even contain important amounts &gt; 2000 µ. Many grain-size distributions are bimodal owing to the mixing of different beach layers by wave action or, in a few cases, to mixing with fluvial sands.

The systematic position of the East Malesian genus Hollrungia K. Sch. within the Passifloracae
Provedor de dados: 16
Autores: Steenis, C.G.G.J. van.
In 1888 K. Schumann described a new, monotypic genus of the Passifloraceae from Papua, Hollrungia aurantioides K. Sch. (Bot. Jahrb. 9: 212). Its generic distinction was largely ascribed to the peculiar sessile, cap-shaped, undivided stigma (“tellerformige Narbe”) and a 3-angular ovary. Harms, who elaborated Passifloraceae for the first and second editions of the “Pflanzenfamilien”, provided a figure of a section of the flower and a cross-section of the ovary (1.c. 3, 6a: 86, fig. 25 E-F. 1893, and 21: 495, fig. 218 E-F. 1925), maintaining Schumann’s observation that Hollrungia possesses an androgynophore which brings it alongside Passiflora, but differing from that genus by the undivided cap-shaped stigma. This kind of stigma is rare in the Passifloraceae...

Taxonomists working with material collected by the Sarawak Forest Department have often been hard put to decide how to quote numbers.

I have tried to unravel the history of the Sarawak Forest Department herbarium number series in order to provide a guide to unequivocal citation. This has not been easy, as all collecting books previous to 1951 have disappeared, apparently during the second world war; many of the herbarium collections are now missing at Kuching and Kepong, where most were distributed, for the same reasons, though there seem also to have been large gaps in the series where numbers were never used.

Palynological data on the history of tropical savannas in northern South America
Provedor de dados: 16
Autores: Wijmstra, T.A.; Hammen, T. van der.
A number of pollen diagrams from the Llanos Orientales of Colombia and the Rupununi Savannas of Guyana show that the actual open savannas were preceded by a closed savanna woodland or dry forest with Byrsonima as principal pollen producer. Human influence during the last 3000 years was apparently an important factor in the extension of open savannas. Nevertheless, open savannas occurred also earlier in the Holocene. Even in approximately Late-Glacial time, open savanna sometimes extended temporarily at the expense of the dry forest or woodland. It seems that climatic and atmospheric influences (periods of very dry climate, lightning) were the cause of these extensions. The pollen diagrams suggest anyhow a very unstable equilibrium between the woody...

Some notes on the delimitation of genera in the Campanulaceae. I
Provedor de dados: 16
Autores: Gadella, Th.W.J.
The delimitation of genera in the Campanulaceae, especially in the subtribe Campanulinae, meets with serious difficulties. Linnaeus (1753, 1754) distinguished 3 genera: Campanula, Phyteuma, and Trachelium. In A. de Candolle’s (1830) monograph of the family 334 species were recognized, classed in 21 genera. Species of 12 of these genera had formerly been included in Campanula. Yet the genus Campanula still appears too inclusive, and the delimitation of some other genera is open to dispute. Not only the delimitation of genera presents serious difficulties, there is also no common opinion on the arrangement of the genera in tribes. The more important systems are those of Schönland (in Engler and Prantl, 1894) and of Fedorov (1957). Schönland arrived at the...

Among the unnamed material of Celastraceae received from the Paris Herbarium for determination, there was one flowering specimen of Microtropis, collected by M. Schmid from South Vietnam in 1953. It was difficult to name it to species with certainty. In order to clarify its identity, I received kind help from the Herbaria of Kew and Paris by sending me specimens on loan for comparison. After studying the specimens concerned, I have concluded that the collection of Schmid represents an undescribed species.

Zur systematischen Stellung der Caprifoliaceengattung Kolkwitzia Graebn

Auf Grund ihres Fruchtknotenbaues konnte die Gattung Kolkwitzia schon bei ihrer Beschreibung durch Graebner (1901a) den Linnaeeae zugeordnet werden, und zwar gehört sie nach Graebner “unmittelbar neben Linnaea”. Dabei ist freilich zu bemerken, dass Graebner (1901b) dem Vorschlage von (Braun und) Vatke (1871) folgend unter dem Gattungsnamen Linnaea die Gattungen Linnaea L. und Abelia R. Br. zusammenfasste. Als besonderes Kennzeichen der Gattung wird von Graebner hervorgehoben, dass die Ovarien der Blüten gewöhnlich paarweise miteinander verwachsen sind. Durch diese Verwachsung von Fruchtknoten je zweier benachbarter Blüten “erinnert sie an Lonicera, bei der jedoch beide auf einer Höhe stehen, während sie bei Kolkwitzia in der bisher nicht bekannten Weise,...

When Dr. Cunningham died in 1962 the manuscript of this monograph was still uncompleted. Miss J. M. Dingley, with the assistance of her staff, undertook to make it ready for publication. The result is a well-edited companion-volume to the previously published “The Thelephoraceae of Australia and New Zealand”. Only species are included ‘authentic’ specimens of which were examined. Under a section “Unknown and Rejected Species” a long list of names is given “of species listed by earlier workers but of which specimens have not been available for study, are not in the region, or which were based on faulty identifications”.

An undescribed species of Mycetia Reinw. (Rubiaceae) from India
Provedor de dados: 16
Autores: Deb, D.B.
The present paper describing a new species of Mycetia Reinw. ( Rubiaceae) is based on a collection by J. L. Lister in 1874—75 and subsequently by G. King’s Collector Badul Khan in January, 1890 from Dafla Hills, NEFA. The late Dr. G. King named the taxon Adenosacme listeri King MSS which was not published. Later on I. H. Burkill in Rec. Bot. Surv. India 10 (1925) 298 named his specimens ( Burkill 36423 &amp; 37321) from the Abor Hills Adenosacme listeri King without description. An examination of Burkill’s specimens in the herbarium (CAL) reveals that his collection is not conspecific with Lister’s, named by King. Very recently G. Panigrahi &amp; S. K. Kar in Bull. Bot.

Canarium sect. Africanarium nov. sect. (Burseraceae)
Provedor de dados: 16
Autores: Leenhouts, P.W.
In my revision of the genus Canarium (Blumea 9, 1959, p. 275—475), C. schweinfurthii was included in sect. Canarium and within this section in the denticulatum-group (see p. 382). The main arguments for giving it that position were: 1. its general resemblance in several characters with sect. Canarium, more specially the apparent morphological equality of its stipules, a key character in the genus; 2. its apparent relationship to C. madagascariense Engl. the inclusion of which in the denticulatum-group is beyond any doubt, and, 3., its geographical position at the end of the chain of species forming the denticulatum-group — from W. Malesia to E. Africa, C. schweinfurthii being restricted to W. and Central Africa — without any connection to other groups of...

Florae Malesianae Precursores XLIV. The fern-genus Elaphoglossum in Malesia, with descriptions of new species
Provedor de dados: 16
Autores: Holttum, R.E.
During the preparation of a monograph of the genus Elaphoglossum for Flora Malesiana, I have recognized twenty-three new species; these are here described. I take this opportunity also for publishing a few comments on the genus. In both these matters I wish to acknowledge the work of Mr P. R. Bell, who began a series of morphological studies of Elaphoglossum some years ago, primarily based on species he had seen in tropical America (see Bibliography); Mr Bell also made a quite intensive study of scales and other characters of some species from Malesia, and has handed over his notes for my use; two of the species here described as new were so recognized and named by him. Most of the new species here dealt with are from New Guinea, which indoubtedly has a...

Dutch studies on coastal sand dune vegetation, especially in the Delta region
Provedor de dados: 16
Autores: Maarel, E. van der.
A short history of Dutch dune vegetation research is presented as an introduction to the present research in the Delta region. Remarkably enough the main results of dune research were presented as dissertations. The classics F. Holkema, L. Vuyck, J. Jeswiet, J. Bijhouwer and W. van Dieren are mentioned. The broadening basis is marked by the outstanding thesis of V. Westhoff, the first all-round phytosociological and ecological study of Dutch dunes. New ideas from this work are mentioned. The work of some pupils and collaborators of Westhoff is discussed. The new approach consists of concentration of the research in the Delta region, development of new ideas and establishment of field stations in the dunes. The scientific value of the Delta dunes is...

C'est en 1921 que Lestage a créé le genre Polyplocia pour un Euthyplociide du Tonkin, P. vitalisi.

This is a difficult book on account of the very wide range and complexity of its subject-matter, made more difficult by the fact that the author has not taken the trouble to arrange his writing so as to present a clear sequence of ideas; also he often uses needlessly complex sentences, some made more difficult to understand by careless proof-reading. After a first attempt to read the book through, my mind was quite confused; it was only on a second reading, by referring backwards and forwards to different chapters, that I began to have some understanding of its basic ideas. So if in this review I do not do it justice, I feel that the author will be at least in part to blame. Prof. Meeuse has made an attempt to interpret the floral morphology of flowering...

Remnants of decalcified nacreous layers from Ordovician, Devonian, Carboneferous (including Pennsylvanian), Permian, Jurassic and Cretaceous, nautiloid and ammonoid shells, examined in the electron microscope, consists of various, biuret-positive structures, which reflect degrees in degradation of the original conchiolon sheets. Identification of these structures as altered nacreous concholin and discrimination from contaminating structures of foreign organisms, a frequent finding in fossil shells, were based on detection of similar structural modifications in the Recent &lt;i&gt;Nautilus&lt;/i&gt; shell, in well preserved shells of Pennsylvanian and Mesozoic cephalopods and in alterations produced artificially in experimental diagenesis of the Recent...

Agriculture as surface water polluter in the Danube River Basin and Central and Eastern Europe
Provedor de dados: 21
Autores: Znaor, Darko; Vollenbroek, Johan; Csikos, Imre.
More than a half of the territory of Central and Eastern Europe (CEE) is used for agricultural activities and agriculture represents an important economic activity of the region. But at the same time, agriculture in CEE is also a serious source of environmental degradations/pollution among which loss of biodiversity, soil and water ones seem to be most obvious. Moreover, regarding the pollution of water resources, particularly the surface water in CEE, it has been shown by several studies that agriculture represents major, much more serious source of pollution than any other sector (e.g. industry, transport, population, etc.). Among these studies, the results from the recent Danube Environmental Integrated Study, done within the framework of the UNDP...

In Papua and New Guinea today a rapidly growing market economy, and a primitive subsistence economy exist side by side. Australian policy calls for more economic development and quicker advancement of the indigenous people. This means that tribal subsistence society must be drawn increasingly into the development of the market economy. Broad strategies for reaching these objectives are considered along with a closer examination of problems of land tenure, wage policy and planning machinery.

Autores: Parker,   M.L.; Yeow,   A.G.
One measure of the economic activity generated by the primary sector is the extent to which the demand for its products is retained within the sector or is transmitted elsewhere. In this article an analysis is made of these inter-relationships between industries and between each industry and the trade sector, as they influence the rate and direction of economic growth in Western Australia. Two input-output models of the Western Australian economy are then used to examine structural changes implied in changes in input coefficients over time.

RURAL EXTENSION AND THE AGRICULTURAL ECONOMIST
Provedor de dados: 31
Autores: Druce,   P.C.
The role of the agricultural economist in rural extension is discussed with particular reference to the changing structure of extension, exemplified by the development of private consulting services and the changing orientation of extension from purely technical considerations to problems of management. The status of the agriculturist generally, and of the extension worker in particular, is also examined and it is concluded that the status of extension as a profession must be raised if the results of technical and economic research in agriculture are to be utilised effectively.

The aims of this project include the study and use of programmed instruction as a means of explaining to Telfarm cooperators the functions of the Telfarm system with emphasis on the proper methods of recording input data.  Unfortunately, time will not allow me to study the effects of programmed instruction on Telfarm cooperators in order to have a better estimate of its usefulness in this type of situation.  But, I will present the need for a change in the present method of instruction and will exhibit the potential available through use of programmed instruction.

This annotated bibliography on agricultural marketing and economic development has been compiled with two objectives in mind.  First, to contribute to the understanding of the role that agricultural marketing can play in the process of developing countries.  As the reader will see many authors agree that marketing is "the most backward of all areas of economic life".  There are several explanations for this particular situation.  Because of socio-political reasons, people in planning roles prefer to allocate resources to the production of physical goods and not of services, which is what marketing mainly provides.  Others believe that an adequate marketing system will spring up automatically with the progress of the country in the road of development.  In...

SUPPLY RESPONSES IN THE SOUTH AUSTRALIAN POTATO INDUSTRY
Provedor de dados: 31
Autores: Mules,   T.J.; Jarrett,   Frank G.
The potato industry in South Australia is characterised by very unstable prices. One hypothesis for this instability is that potato growers' acreage responses follow a cobweb pattern, that is, a one year lag of acreage to price. This hypothesis is tested, together with a two year lag and a distributed lag. The distributed lag model seems the most satisfactory and gives a short-run elasticity of acreage to price of 0.36 and a long-run elasticity of 1.09. An alternative to the lagged price hypothesis is the "constant cash return" hypothesis which postulates that potatoes are grown to provide a certain cash income to permit farm development. This explanation of acreage response only seems relevant in the dairying and fat lamb areas of the State.

SOCIAL GAIN, WELFARE, POLITICAL ECONOMY AND A' THAT
Provedor de dados: 31
Autores: Kelso,   Maurice M.
The economic criterion of public investment choice is aggregate consumers' surpluses and producers' rents generated by the investment. Its analytical model is a social revenue function and a social cost function. It is a welfare criterion only so far as efficiency is a welfare component and then subject to severe limitations. It is argued here that the economist's conclusions rest in part on a set of value preferences; therefore, the test of their rightness is in part their acceptability to the public choice-maker.

COMPARATIVE ANALYSIS OF FARM ACCOUNTS
Provedor de dados: 31
Autores: Burns,   E.O.
With the development of farm management extension services in Australia, a need has arisen for an analytical technique which can be handled by extension officers and readily comprehended by farmers. Inter farm comparison met this need at a similar stage of development in the United States and United Kingdom, and its application to Australian conditions is discussed. Comparative analysis is presented as an integral feature of farm management accounting.

THE SEASONALITY OF PRICES RECEIVED AND PRICES PAID BY THE UNITED STATES FARMERS
Provedor de dados: 31
Autores: Olayemi,   Joseph.
Seasonal indices represent the percentages that the prices for a particular month are of the yearly average price when the effects of major changes in demand, and year-to-year changes in supply are eliminated.  The indices represent general tendencies in prices; they do not indicate what actual prices will be in certain periods.  This paper is concerned with the analysis of the seasonality of prices received and paid by farmers between 1945 and 1965.

FOOD FOR WORK PROGRAMS:  AN ANALYSIS OF CONTRIBUTIONS AND LIMITATIONS
Provedor de dados: 31
Autores: Andrew,   Christopher O.
This paper focuses on one section of the Food For Peace program.  Essentially, it emphasizes combing surplus labor and food in a work program to accelerate development and expand future income flows.  An analysis of potential contributions and limitations of food for work programs requires raising a number of specific questions.   The problem at hand for this section of the Food For Peace program is to favorably induce:  changes in consumption patterns and human welfare, improvements in human dexterity and fitness, development of physical capital, and mobility of resources.  The problem for food for work programs includes uniting surplus labor and food to effectively achieve these goals.

ECONOMIC ASPECTS OF THE POTATO ENTERPRISE WITH PARTICULAR REFERENCE TO COSTS
Provedor de dados: 31
Autores: Kearney,   Brendan.
Although potatoes are grown in most countries of the world, the pattern of production is largely concentrated in Europe where almost three-quarters of the world's acreage is grown. The Americas account for somewhat over 7 percent of total acreage of which over one-half is grown in the southern continent.  In terms of production, this concentration is even more marked with 86 percent of the total coming from the aforementioned areas.  Thus it is noted that it is in European countries and those areas of the world largely populated by the descendants of Europeans that the potato finds favor despite the fact that it originated in Peru and was first used by peoples of Asiatic origin as an item in their diet.  The purpose of this paper is to examine and review...

Autores: Ryan,   James G.
While a number of the conclusions arising from this study have reference specifically to the irrigated areas of southwestern New South Wales, a substantial part has particular relevance to the study of machinery economics generally. Perusal of the main conclusions listed below will illustrate this.  Evaluation of the economic pros and cons of header ownership versus the employment of contractors for harvesting irrigation crops in southwestern New South Wales is one of the prime purposes of this paper. Definition of break-even crop area combinations is of the utmost importance to prospective header owners, as these days more farmers are buying their own headers and as a result the availability of "off-farm" contract harvesting to offset ownership costs is...

Effective limitations on farm working capital are not easily identified but behaviour consistent with such limitations is observed. Using a linear programming analysis, the results of having limited working capital are shown. It is also shown that the value of the working capital resource is so high that farmers make every endeavour to keep it free from limitation.

Os autores planejaram um experimento com a finalidade de esclarecer vários problemas ligados com a polinização da aboboreira. Para êsse fim, foi organizada uma cultura com a variedade Brasileira. O campo constou de 48 covas, cada qual com uma planta, distanciadas de 2m. As plantas foram conduzidas em caramanchões de 1m de altura, separados por corredores de 3 m. Cada caramanchão abrangeu 4 plantas. Com a finalidade de se estudar a polinização na ausência de insetos, três caramanchões foram cobertos com telas de "nylon". Os resultados das pesquisas, foram os seguintes: 1.° - A proporção de flôres femininas e masculinas abertas no mesmo dia foi de 1:17,7. 2.° - A abertura das flôres se dá em plena madrugada. 3.° - As abelhas Irapuás (Trigona (Trigona)...

Resistência de Xanthomonas campestris com relação à tilosina e vancomicina
Provedor de dados: 43
Autores: Azevedo,J. Lúcio de; Menezes,Tobias J. B. de.
Foi estudada a resistência da bactéria fitopatogênica Xanthomonas campestris (Pammel) Dowson com relação a dois antibióticos: Tilosina e Vancomicina. Para a vancomicina, colônias resistentes apareceram até na mais alta concentração usada (256 mcg/ml.). Para a tilosina, em concentrações maiores que 128 mcg/ml não foram encontradas bactérias, resistentes. Tais resultados indicam que a X. campestris seguiu o modelo de "um só passo" para adquirir resistência a vancomicina e, o modelo de "múltiplos passos" com relação a resistência a tilosina.

Com o objetivo de estudar a resposta do amendoim à aplicações isoladas e combinadas de N, de P, de K e Ca, realizou-se um ensaio fatorial 2³ para N P K, com aplicação do calcáreo em metade de cada parcela. O experimento foi conduzido no Município de Bariri, Estado de São Paulo. Apenas a calagem aumentou a produção significativamente. O potássio exerceu efeito positivo nas concentrações de nitrogênio, de fósforo e de potássio das fôlhas, embora a sua concentração não tenha aumentado significativamente em todos os tratamentos. A correlação entre teor de K nas fôlhas e a produção foi positiva e altamente significativa.

A relação K/Mg em plantas jovens de laranjeira (Citrus sinensis L., Var. D.A.C)
Provedor de dados: 43
Autores: Mello,P. A. F. de; Haag,H. P.; Brasil Sobrº,M. O. C.; Montenegro,H. W. S.
A análise das folhas das plantas revelaram que a absorção de Mg e de K aumentaram com a concentração do elemento respectivo na solução. O Mg não interferiu na absorção do K nos tratamentos correspondentes à omissão e dose 2 deste nutriente; nos tratamentos correspondentes à dose 1, 48 p.p.m. de Mg nas, soluções nutritivas estimularam a absorção de K. O K inibiu a absprção de Mg nos tratamentos correspondentes às doses 0 e 2 deste elemento: quanto na presença da dose 1, 234, p.p.m. de K nas soluções nutritivas determinaram maior concentração de Mg nas folhas. O K teve ação antagônica sobre o Ca; o Mg teve efeito semelhante só quando na presença da dose mais elevada de K. Na ausência desse elemento ou na presença de 234 p.p.m. dele o efeito do Mg foi...

Problemas fitogeográficos de São José do Rio Preto, estado de São Paulo, Brasil
Provedor de dados: 43
Autores: Marinis,Giorgio de; Camargo,Paulo Nogueira de.
O Município de São José do Rio Preto, Estado de São Paulo, Brasil, cujas principais características climáticas e pedológicas estão indicadas no trabalho, apresenta área florestal reduzida e fragmentária, sendo, em sua maior parte, ocupada por formações mais, ou menos savanizadas e, em menor grau, ruderalizadas. Foram, até agora, encontradas espécies vegetais pertencentes a cinco elementos fitogeográficos diferentes: o Geral, o Amazônico, o Atlântico, o Meridional e o Central. Embora nada se possa dizer, com segurança, em relação à formação clímax da região, pode-se admitir que seja a floresta latifoliada tropical, semidecídua e mais ou menos xeromorfa. Continua em aberto, para a região, o problema da origem do cerrado.

Mensurações dos traqueídos de Pinus Elliottii pelo método microscópico
Provedor de dados: 43
Autores: Santos,Clóvis Ferraz de O.
O presente trabalho trata-se da comparação dos traqueídos de Pinus elliottii procedida pelo método microscópico em material dissociado, empregando-se dois critérios diferentes, com a finalidade de se saber qual dos dois, seria mais vantajoso e mais rápido devido a troca constante de objetivas de aumentos diferentes para se obter os valores dos comprimentos e das espessuras. Pelo primeiro critério tanto o comprimento como a espessura foram tomadas do mesmo elemento, e pelo segundo as medidas do comprimento e das espessuras não foram tomadas necessàriamente dos mesmos elementos. A análise estatística provou ser os dois critérios corretos. Sendo o segundo critério mais, fácil e rápido que o outro, vê-se portanto ser perfeitamente apropriado o seu emprego nos...

Autores: Mariconi,Francisco A. M.
Êste trabalho tem como objetivo principal descrever aspectos ecológicos e bionômicos das saúvas de 104 municípios do oeste do Estado de São Paulo. Em tôda a região pesquisada somente três espécies de saúvas foram constatadas: l.ª) Atta sexdens rubropilosa Forel, 1908 (saúva limão); 2.ª) A. laevigata (F. Smith, 1858) (saúva-de-vidro ou saúva cabeça-de-vidro); 3.ª) A. capiguara Gonçalves, 1944 (saúva parda). Uma das grandes surpresas, durante o desenvolvimento dêste trabalho, foi o de se comprovar que a saúva parda A. capiguara é a espécie mais frequente e a mais importante. A sua importância e a das duas outras espécies é, entretanto, salientada no capítulo 5 (BIONOMIA).

Estudos sobre a alimentação mineral do cafeeiro: XIX. extração de micronutrientes na colheita pelas variedades "Mundo novo", "Caturra Amarelo" e "Bourbon Amarelo"
Provedor de dados: 43
Autores: Sarruge,J. R.; Andrade,R. G.; Gomes,L.; Arzolla,S.; Graner,E. A.; Malavolta,E.
Foi determinado o teor de micronutrientes na casca (polpa) e no grão de café "cereja" das variedades "Caturra Amarelo", "Bourbon Amarelo" e "Mundo Novo" colhidos em plantas cultivadas em três tipos de solos - terra roxa legítima, massapé-salmourão e arenito de Bauru. A análise revelou que as três variedades possuem a mesma composição mineral com respeito aos elementos determinados. O tipo de solo - ou o local - influiu na composição das amostras. Em um saco de café em coco existem quantidades aproximadamente iguais dos elementos na casca e no grão.

Autores: Kitajima,E. W.; Costa,A. S.
Partículas esferoidais de 50-60 m¼ de diâmetro foram encontradas em preparações rápidas e em secções ultra-finas de fôlhas de mandioca infetadas pelo vírus do mosaico das nervuras (VMNM), examinadas ao microscópio electrônico. Tais partículas não foram observadas em preparações de plantas sadias ou de fôlhas sem sintomas de plantas infetadas, e são consideradas como representando o VMNM. Em secções ultra-finas de tecido foliar, as partículas do VMNM encontravam-se dispersas em certas áreas do citoplasma, ricas em ribosomas mas pobres em outras organelas citoplasmáticas, e onde esporadicamente apareciam pequenos feixes de fibrilas densas (7-10 m¼ X 100-300 m¼). Massas densas, de textura finamente granulada (0,3-3 ¼ de diâmetro), foram encontradas em alguns...

Adubação de batata-doce com diferentes doses de nitrogênio, fósforo e potássio
Provedor de dados: 53
Autores: Breda Filho,José; Freire,E. S.; Abramides,E.
Em diferentes localidades do Estado de São Paulo foram conduzidas quatro experiências de adubação de batata-doce (Ipomoea batatasLam.) com doses crescentes de nitrogênio, fósforo e potássio. O nitrogênio e o potássio não aumentaram significativamente a produção em qualquer das experiências. O fósforo também não a aumentou em duas delas: uma instalada em área adubada com P nas culturas anteriores, e a outra, em solo bastante fértil. Todavia, nas duas conduzidas em áreas ainda não adubadas, o efeito do fósforo foi altamente significativo e linear, tendo as respostas à dose de 120 kg/ha de P2O5 correspondido a +35 e + 912% das respectivas produções dos tratamentos sem fósforo.

Adubação mineral do feijoeiro: III - Efeitos de N, P, K,da calagem e de uma mistura de enxôfre e micronutrientes, em solo massapê-salmourão
Provedor de dados: 53
Autores: Miyasaka,Shiro; Freire,E. S.; Alves,Sebastião; Rocha,Tulio Ribeiro.
O efeito de diversas adubações sôbre a produção do feijoeiro em solo massapê-salmourão foi estudado em quatro experiências. A resposta ao fósforo foi nula na instalada em área adubada com NPK, nas culturas anteriores, mas elevada nas localizadas em áreas ainda não adubadas. O nitrogênio deprimiu a produção em uma e provocou pequenos aumentos nas demais. O efeito do potássio, tal como o da calagem, só foi positivo em uma experiência. A adição, a NPK, de uma mistura de enxôfre e micronutrientes (Zn, Cu, B e Mo), deprimiu a produção em uma e aumentou-a nas outras três.

Correlação entre composição das fôlhas e produção, e tamanho de frutos, em laranjeira baianinha
Provedor de dados: 53
Autores: Gallo,J. Romano; Hiroce,Rúter; Rodriguez,Ody.
Dados de produção de 4 anos de colheita (1961-64) foram estudados em relação aos elementos minerais contidos nas fôlhas com 6 meses de idade, colhidas anualmente num ensaio fatorial NPK 3X3X3 de longa duração, com laranjeira baianinha (Citrus sinensisOsb.) enxertada sôbre cavalo de laranja caipira (C. sinensisOsb.). As análises da variância dos teores de N e K das fôlhas mostraram efeitos lineares, positivos e altamente significativos da adubação com os respectivos elementos. Êsse efeito, para P, ficou limitado a uma dose do fertilizante. A adubação com superfosfato provocou, ainda, aumento no teor de Ca das fôlhas, significativo ao nível de 1%. Os estudos efetuados revelaram que: o aumento do teor de nitrogênio nas fôlhas aumentou a produção (pêso e...

Provedor de dados: 53
Autores: Miyasaka,Shiro; Freire,E. S.; Abkamides,E.
Em experiência realizada por três anos em solo ácido foi estudado o efeito, sôbre a produção da soja, da calagem com calcário dolomítico e cal extinta, aplicados em sulcos laterais aos de plantio ou a lanço, sòmente no primeiro ano ou parceladamente. O aumento médio de produção proporcionado pela calagem correspondeu a 59%, mas as diferenças entre os dois corretivos e os métodos de aplicação foram pequenas. O efeito imediato das doses empregadas sòmente no primeiro ano foi bem menor que o residual.

Mineralogia dos solos da Estação Experimental "Theodureto de Camargo", em Campinas
Provedor de dados: 53
Autores: Melfi,Adolpho J.; Girardi,Vicente A. V.; Moniz,Antônio C.
São estudadas mineralògicamente séries monotípicas da Estação Experimental "Theodureto de Camargo", município de Campinas. Ocorre na área um sillde diabásio Mesozóico, intrusivo em rochas sedimentares cartaoníferas de origem glacial; os solos aí existentes provêm, então, ora de um ou outro tipo de rocha, ora da mistura de ambos. A série Chapadão originou-se de diabásio, sendo classificada como latossol roxo, vulgarmente denominado terra-roxa-legítima. A série Taquaral, também proveniente da mesma rocha, sofreu, entretanto, grande contribuição de sedimentos de origem glacial, evidenciada pela presença de zircão monazita, sillimanita, turmalina, rutilo, granada, estaurolita e cianita. As séries Venda Grande, Barão e Monjolinho derivaram-se de sedimentos...

Níveis de fertilidade do solo para a cultura algodoeira: II - Correlação entre a produção e o teor de fósforo no solo
Provedor de dados: 53
Autores: Verdade,Francisco da Costa; Venturini,Wanderley R.; Amaral,Álvaro Zingra do; Wutke,Antônio Carlos Pimentel.
Os resultados de 216 experiências de adubação do algodoeiro realizadas no período de 1957 a 1960 foram correlacionados com os teores de fósforo do solo. Em virtude do pequeno número de reações favoráveis à adubação nitrogenada e potássica, sòmente aquele nutriente pôde ser estudado. Verificou-se, porém, que o nitrogênio e o potássio, em níveis baixos (30 kg/ha), dão melhor consistência à ação do fósforo. Considerando-se como 100 a melhor produção, foi possível estabelecer, estatisticamente, a relação entre os teores de fósforo do solo e as porcentagens de produção. A correlação foi altamente significativa, explicando, a linear, cêrca de 50%, e a quadrática, menos de 10%, para os solos do arenito Bauru. Obteve-se a equação que levaria à maior porcentagem de...

Adubação mineral do feijoeiro: V - Efeitos de N, P, K, S e de uma mistura de micronutrientes, em dois solos do Vale do Paraíba
Provedor de dados: 53
Autores: Miyasaka,Shiro; Freire,E. S.; Igue,Toshio; Schmidt,Nelson C.; Leite,Norberto.
Na safra "da sêca" de 1962 conduziram-se, no Vale do Paraíba, quatro experiências de adubação do feijoeiro, tendo-se instalado, em cada localidade, duas em áreas vizinhas, uma das quais recebeu calagem. Onde as experiências foram realizadas numa encosta, sem irrigação, a sêca reduziu dràsticamente as produções e somente se constatou efeito favorável do fósforo. Entretanto, nas conduzidas numa várzea com solo orgânico, com irrigação, as produções foram elevadas. Enquanto o nitrogênio, o potássio e o enxôfre não concorreram para aumentá-las, o fósforo proporcionou grandes aumentos, tanto na área sem calagem como na que recebeu o corretivo. Uma mistura de micronutrientes (Zn, Cu, B e Mo), empregada na presença de NPKS, também provocou grandes aumentos de...

Autores: Grohmann,Francisco; Oliveira,J. Bertoldo de; Queiroz Neto,José Pereira de.
Amostras de solo foram colhidas de parcelas de um ensaio de adubação de milho tratadas com estêrco, calcário e adubação mineral. Os agregados das amostras foram separados em classes de tamanho, e feitas as determinações: análise granulométrica, pH, C e N totais, Ca++ Mg++ e K+ trocáveis e capacidade de troca de cations. Tôdas as amostras tiveram comportamento análogo: as porcentagens de argila diminuiram progressivamente dos agregados maiores até a classe de tamanho 1-0,5 mm, aumentando, a seguir, até atingir seu valor máximo na fração menor que 0,105 mm. Os autores estudaram a influência dos diversos tipos de adubação sôbre as características dos agregados.

São apresentados resultados experimentais da produção de fôlhas em amoreiras de variedades comuns, durante o período de formação das mudas, com os sistemas denominados de cepo e fuste, em duas regiões, Limeira e Tatuí, do planalto paulista. Os resultados quanto à produção de fôlhas, em dois anos em cada região, permitiram as conclusões: Em Limeira, para a variedade Calabreza, o sistema de fuste foi muito superior ao de cepo. Para as variedades Fernão Dias e Lopes Lins, o sistema de fuste foi também superior, porém, de forma menos acentuada. Em Tatuí, no caso das variedades Calabreza e Fernão Dias, o sistema de cepo mostrou-se, ao contrário, mais produtivo. Para a variedade Lopes Lins, não houve diferença entre os dois sistemas de cultivo experimentados.

Amostras de dois solos limo-argilosos foram compactadas, utilizando-se um compactador Bruce modificado. Tanto pela variação da intensidade de compactação como pela variação do teor de umidade do solo, obteve-se uma escala crescente de massas específicas aparentes dessas amostras. Nestas foram plantadas sementes de arroz, para determinar as relações entre a penetração das raízes da planta e a massa específica aparente do solo. Verificou-se que, a partir de determinadas massas específicas aparentes, artificialmente obtidas, a penetração das raízes era totalmente impedida e o desenvolvimento do sistema radicular grandemente reduzido.

Sete experiências de adubação do feijoeiro foram realizadas em áreas freqüentemente cultivadas e adubadas com NPK das estações experimentais de Tatuí (solo Latosol Vermelho Escuro-Orto) e Tietê (solo Podzólico Vermelho Amarelo, variação Laras). Duas dessas experiências foram repetidas no ano seguinte, quando só se empregou a adubação nitrogenada. Incluindo o segundo ano das duas últimas experiências, o nitrogênio aumentou significativamente a produção em cinco casos, o fósforo, em dois, o enxôfre e a mistura de micronutrientes (Zn, Cu, B e Mo), em um, e o potássio, em nenhum.

Em quatro experiências conduzidas em 1960-61 nos municípios de Tietê e Tatuí, estudou-se o efeito de várias adubações sôbre a produção do feijoeiro. O fósforo não a modificou nas duas localizadas em áreas já repetidamente adubadas com NPK, mas proporcionou aumentos substanciais na instalada em terreno de cerrado recém-desbravado e na realizada em área moderadamente adubada na cultura anterior. O efeito do nitrogênio foi favorável em duas experiências, e o do potássio, em uma. A resposta à adição, a NPK, de enxôfre e micronutrientes (Zn, Cu, B e Mo), foi negativa, em um caso, e práticamente nula nos demais. Conquanto os solos estudados tivessem pH de 5,0 a 5,6, a calagem só aumentou a produção em uma localidade.

Autores: Queiroz Neto,José Pereira de; Oliveira,J. Bertoldo de; Grohmann,Francisco.
Com a finalidade de definir o estado estrutural de um podzólico vermelho amarelo-orto, bem como a sua variação frente a diferentes formas de uso, foram feitas as análises de amostras de solo das seguintes parcelas da Estação Experimental de Monte Alegre do Sul: a)cultura de milho durante 15 anos; b)pomar de frutas de clima temperado, em produção; c) eucalipto de 2.° corte. Procedeu-se à análise granulométrica e às determinações de pH, C e N totais, Ca++, Mg++ e K+ trocáveis. Foram determinados o estado de agregação, por peneiragem a sêco, e a estabilidade nágua dos gregados. Os resultados mostraram redução do diâmetro médio geométrico dos agregados da parcela "eucalipto" (2,55 mm) para a "pomar" (2,35 mm) e desta para "milho" (2,25 mm). A redução da...

Autores: Miyasaka,Shiro; Freire,E. S.; Mascarenhas,H. A. A.; Nery,Clóvis; Campana,Mário; Sordi,Guido de.
O efeito da adubação verde com uma graminea e quatro leguminosas na cultura do feijoeiro "da sêca" foi estudado em quatro experiências instaladas em terra-roxa-misturada, no Estado de São Paulo. Os adubos verdes foram semeados em outubro e cortados com 2,5 a 3 meses de idade, tendo sido o feijoeiro plantado entre 12 de fevereiro e 4 de março. As áreas experimentais receberam adubação mineral uniforme. Em média das quatro experiências, a testemunha produziu 374 kg/ha. Enquanto o efeito do sorgo forrageiro foi pràticamente nulo e os aumentos de produção provocados por lablabe, tefrósia e guandu variaram entre 158 e 185 kg/ha, o proporcionado pela crotalária (C. junceaL.) atingiu 318 kg/ha ou 85%.

Adubação da batata-doce com nitrogênio, fósforo e potássio em terrenos de "cerrado"
Provedor de dados: 53
Autores: Breda Filho,José; Freire,E. S.; Abramides,E.
Em um esquema fatorial com os níveis 0, 40, 80 kg/ha de N e 0, 60, 120 kg/ha de P2O5 ou K2O, foram conduzidas, no Estado de São Paulo, seis experiências de adubação da batata-doce (Ipomoea batatas Lam.) em áreas que tiveram vegetação de cerrado e haviam sido, ou não, adubadas nos anos anteriores. O nitrogênio só aumentou significativamente a produção em uma experiência. O efeito do fósforo foi muito pequeno nas duas localizadas em áreas já adubadas, mas em média das outras quatro, conduzidas em solos ainda não adubados, as respostas às doses 1 e 2 atingiram, respectivamente, + 33 e +51%. Em todos os casos, o potássio aumentou significativamente a produção, tendo as respostas médias às doses 1 e 2 correspondido a, respectivamente, + 25 e +30%.

Autores: Silva,Jairo Ribeiro da; Garcia Blanco,H.; Normanha,E. S.; Freire,E. S.
Numa experiência preliminar para estudar o efeito de doses crescentes dos três elementos essenciais sôbre a mandioquinha-salsa, sòmente o fósforo aumentou substancialmente a produção de raízes, tendo as doses de 80 e 160 kg/ha de P2O0 proporcionado respostas iguais, de +29%. Enquanto o efeito de 80 kg/ha de K(2)0 correspondeu a +14%, o da dose dupla foi nulo. Nas doses de 50 e 100 kg/ha, o nitrogênio deprimiu linearmente a produção.

Autores: Oliveira,Domingos de Azevedo; Montojos,J. Casado; Igue,Toshio; Miranda,Hilário da Silva; Freitas Júnior,Martinho Lúcio de.
São relatados os resultados de três ensaios de adubação de arroz de sequeiro, com o cultivar 'Dourado Precoce'. O esquema estatístico foi o fatorial 3 X 3 X 3 para N, P e K, com um tratamento extra de micronutrientes. Os ensaios foram localizados na variação Lins, dos solos Podzolizados de Lins e Marília. Em duas localidades houve efeito para a adubação nitrogenada. A dose de 30 kg/ha de N foi suficiente para o máximo efeito. A adubação fosfatada proporcionou a maior produção com 60 kg/ha de P2O5, em dois casos. No terceiro, esta foi alcançada com 120 kg/ha. O potássio e a mistura de micro-elementos não trouxeram acréscimos significativos na produção.

Capacidade de troca de catíons em solos: estudo comparativo de alguns métodos
Provedor de dados: 53
Autores: Raij,Bernardo van; Küpper,Alfredo.
É apresentado um estudo comparativo e crítico de alguns métodos de determinação da capacidade de troca de cations em solos. A capacidade de troca de cations foi determinada diretamente, pelo método do acetato de amônio, e indiretamente, somando as bases trocáveis com a acidez extraída dos solos por percolações, respectivamente pelo acetato de cálcio neutro e pelo cloreto de bário tamponado pela trietanolamina a pH 8,2. No método do acetato de cálcio, foram ainda estudadas duas simplificações, utilizando uma técnica de agitação, e outra aplicando um cálculo hiperbólico às duas primeiras percolações. Foram encontradas excelentes correlações entre o método de percolação pelo acetato de cálcio e os demais métodos. Os métodos do acetato de amônio é acetato de...

Efeito do tamanho de agregados sôbre o crescimento e sistema radicular do milho
Provedor de dados: 53
Autores: Grohmann,F.; Queiroz Neto,José Pereira de.
Agregados das classes de tamanho 7-4, 4-2, 2-1 e &lt; 1 mm, dos solos latossolo roxo e podzólico vermelho amarelo-orto, foram colocados em vasos de vegetação, para permitir a observação do crescimento da parte aérea e do sistema radicular do milho naqueles diferentes tamanhos de agregados. Verificou-se que o comportamento das plantas foi diferente num e noutro solo. No latossolo roxo, a classe de tamanho de agregados mais conveniente para o crescimento da parte aérea e do sistema radicular foi a &lt; 1 mm; no podzólico vermelho amarelo o maior desenvolvimento da planta se deu nas classes de tamanho 4-2 e 2-1 mm. A causa da variação do crescimento das partes aéreas e do sistema radicular parece estar ligada ao comportamento fisico do solo. Assim, para os...

Estudo genético de bacia orgânica do Vale do Paraíba
Provedor de dados: 53
Autores: Verdade,Francisco da Costa; Hungria,Luiz Soares.
Através de sondagens, fotointerpretação do relêvo e altimetria, foi estudada a formação duma bacia orgânica situada entre São José dos Campos e Caçapava. Esta bacia teve sua origem provável em um lento abatimento por acomodação de camadas no substrato terciário da planície aluvial. Êste fenômeno propiciou o acúmulo orgânico abaixo do nível atual do rio. A preservação da bacia, situada ao sul do rio, sem destruição pela oscilação meândrica, deve-se à tendência do leito em se deslocar para o norte, conforme comprovam os terraços. Estas condições devem prevalecer em outras áreas do mesmo rio e que possuam espêssas camadas orgânicas.

Em oito experiências de adubação do feijoeiro, para estudar os efeitos de diversos elementos em solo massapê-salmourão, o fósforo aumentou significativamente a produção em três localidades, o nitrogênio, em uma, e o potássio, sómente no segundo ano de uma experiência conduzida por dois anos. A adição, a NPK, de enxôfre ou de micronutrientes, não modificou significativamente a produção em qualquer das localidades. Os efeitos residuais do fósforo e dos micronutrientes, observados em três experiências, foram maiores que os imediatos.

Autores: Miyasaka,Shiro; Camargo,A. Paes de; Inforzato,Romeu; Igue,Toshio.
Foram estudados o comportamento da massa vegetal não decomposta de leguminosas e de gramíneas e seus efeitos, quando incorporada ao solo antes do plantio do feijão. A incorporação ao solo de massa vegetal não decomposta acarretou: a)maior retenção de umidade e menor variabilidade térmica do solo, embora em menor grau que no solo com cobertura morta ("mulch"); b)tendência para formação de maior número de nódulos, principalmente quando a incorporação é de graminea; c) aumento no teor de potássio nas folhas, no desenvolvimento da parte vegetativa e radicular e na produção de sementes do feijoeiro. Êstes efeitos foram particularmente significativos quando da aplicação de soja perene, quer incorporada, quer em cobertura.
