| Resumo Com base em observações do abdome pupal de algumas espécies neotropicais de Simuliini e Prosimuliini, sem o uso do KOH (Hidróxido de Potássio) como agente "limpador-clarificante", são propostas algumas alterações nas definições apresentadas por Crosskey (1969) e por Wygodzinsky & Coscarón (1973) para estas tribos: Simuliini com áreas membranosas estriadas longitudinais medianas nos esternitos V, VI-VII e algumas vezes também no VIII; Prosimuliini somente apresentando áreas estriadas membranosas longitudinais, medianamente, nos esternitos VI-VII e algumas vezes também no VIII. |

| En Noreste de Brazíl, existe una gran variabilidad de factores de orden físico, biológico y socío-economíco, los cual es han contribuído para dísmínuír el desarrollo agrícola y ganadero de Ia regíón. Por otra parte, el agricultor tradicional a nível de subs ístencia, rechaza fuertemente Ias nuevas tecnologtas, fundamentalmente por no entender claramente Ia justificación de una determinada práctíca, ya que Ias tecnologías modernas no harrconstderado sus condícíones socia.les y economícas. Sin embargo, el "Centro de Pesquisa Agropecuaría do Trópico Semi-Ar ído'' (CPATSA/EMBRAPA), en Petrolina, PE., Brazíl , considera conveniente Ia conjugacíón de Ia tecnologta moderna con Ios sistemas tradícíonales, a través de un equipo interdisciplinario e inter... |

| El presente trabajo contiene una lista de las especies de Majidae colectadas en la bahía de Piscadera al Sur de Curasao. De las 16 especies encontradas solo una (Stenorhynchus seticornis) había sido reportada para esta Bahía, según los trabajos de Rathbun, (1924, 1925). De estas especies cinco no se habían mencionado en trabajos anteriores para Curacao. |

| Sementes de picão-preto (Bidens pilosa L.) foram germinadas em placas de petri sobre papel de filtro molhado com diferentes concentrações de fluometuron (0, 5, 25, 125 e 625 ppm). O ensaio foi conduzido em condições de laboratório, com variação de temperatura entre 24°C e 28°C e intensidade luminosa máxima de 600 lux e foi encerrado após sete dias (168 horas). O fluometuron diminuiu a germinabilidade e o comprimento da radídula e do hipocótilo, afetou o formato dos cotilédones e, nas concentrações mais elevadas, impediu a rejeição do pericarpo. Os efeitos observados não são atribuíveis a lesões bioquímicas do processo fotossintético. |

| The lagoon of Brusc located on the Mediterranean coast (VarFrance) is subjected to climatic and hydrologic particular conditions. The low values observed for nutrient into the sea water affect the evolution of phytoplankton. Thus chlorophyll concentration measured in the lagoon give an annual average of 0.42 mg. m-3 . The growth of two bivalves species : Cerastoderma glaucum and Venerupis semidecussata was compared between two stations where one population of each species are implanted. The culture of this molluscs is made in the lagoon and in outdoor pound dug on the old salt-pan near at hand. In the pound, subjected to natural climatic conditions, a great growth is noted for this two species. The growth rate appear better than the populations of the... |

| Allium paradoxum, a native of S.W. Asia and naturalized for over a century in Britain, Germany and Czechoslovakia, has also established itself at some localities in the Netherlands. In some woodlets on the inner side of the dunes near Heemstede and Bloemendaal (prov. of Noord-Holland) it is locally abundant, being known from these findspots since c. 1918 and 1957 respectively. Moreover, the species was recorded from similar localities near Wassenaar and Oostvoorne (prov. of Zuid-Holland), but on the former spot it has vanished possibly due to human activity and on the latter it has not spread very much thusfar. It is the author’s opinion that A. paradoxum should be considered a member of the Dutch flora because of its naturalizing on at least two... |

| .-Alkali metals prove to be very sensitive to alteration process even if this process is moderate. It is very difficult to use these elements to trace magmatic processes since their concentration may Vary within an homogeneous "unaltered" unit. From all the basaltic units investigated, a classification of "low partition coefficient" elements is presented (Sc, Ti, V, Y, Zr, Nb, La-Tb , Hf, Ta, Th) . The incompatible elements ratios (Y/Tb, Zr/Hf, Nb/Ta) are constant in the samples studied and are nearly equal to the same ratios in chondrites. This is consistent with the existence of an homogeneous primordial mantle at the scale of the North Atlantic, compatible with a chondritic composition of the earth. [NOT CONTROLLED OCR] |

| In 1977 hebban we in het gebied rond Ambleteuse amfibieën bestudeerd. Bij inventarisatie troffen we Triturus vulgaris, T. helveticus, T.alpestris, T.cristatus. Rana temporaria, Hyla arborea, Bufo bufo, B. calamita, Alytes obstetricans, Pelodytes punctatus en Salamandra salamandra aan. Verschillend van voorgaande jaren was dat T.helveticus midden in de duinen bij Ambleteuse werd gevonden en dat P.punctatus frequenter en ook iets noordelijker voorkwam. R.arvalis en R.esculenta zijn in tegenstelling tot ’74 en ’75 niet aangetroffen. De vangstresultaten over de afgelopen vier jaar in de poelen die wij bezocht hebben, zijn gerangschikt in een tabel. Met behulp van gemerkte dieren konden we in een klein gebied, met dicht bijelkaar gelegen poelen aantonen dat... |

| Ce rapport présente les résultats du suivi cartographique et géomorphologique de la pollution des côtes bretonnes par le pétrole de l'AMOCO CADIZ jusqu'au mois de Mars 1979, c'est-à-dire un an après la catastrophe. Les reconnaissances aériennes associées à des visites détaillées des 160 stations établies entre la pointe ST MATHIEU et le sillon du TALBERT ont permis de suivre l'arrivée du pétrole à la côte puis sa disparition plus ou moins rapide. Pour dresser ce bilan, plus d'une vingtaine de vols ont été effectués ainsi que 5 campagnes de terrain ; débutés immédiatement après le naufrage de l'AMOCO CADIZ en collaboration avec de nombreux organismes, ces travaux se sont poursuivis à partir de Novembre 1978 dans le cadre du programme de suivi écologique... |

| Groundwaters (in wells, springs, caves, macroporous interstitia...) of 29 Caribbean islands have been investigated. Only on the four islands off the coast of Venezuela (viz., Aruba, Curaçao, Bonaire, and Margarita) members of the suborder Ingolfiellidea (Crustacea, Amphipoda) have been encountered, altogether six species, of which three are described here for the first time. The zoogeographical implications of this limited range in the West Indies is discussed. |
