Exploratory fishing for tunas and tuna tagging in the Marquesas, Tuamotu, Society, Pitcairn, and Gambier Islands

The Marquesas Islands are located in the Pacific Ocean at about 9 degrees south latitude and 140 degrees west longitude (Figure 1). It has been demonstrated by tagging (Anonymous, 1980b) that skipjack tuna, Katsuwonus pelamis, which occur in the northeastern Pacific Ocean have migrated to the Hawaiian Islands and Christmas Island in the central Pacific and also to the area between the Marshall and Mariana islands in the western Pacific. The Tuamotu, Society, Pitcairn, and Gambier islands, though the first two are not as close to the principal fishing areas of the eastern Pacific Ocean as are the Marquesas Islands, and the last two are small and isolated, are of interest for the same reasons that the Marquesas Islands are of interest, and thus skipjack should be tagged in those islands for the same reason that they should be tagged in the Marquesas Islands. The organizations which participated in the Marquesas Islands tagging and other scientific activities were the Inter-American Tropical Tuna Commission (IATTC), the South Pacific Commission (SPC), the Centre National pour l'Exploitation des Oceans (CNEXO), the Office de la Recherche Scientifique et Technique Outre-Mer (ORSTOM), the Service de la Peche de la Polynesie Francaise (SPPF), and the Service de l'Economie Rural (SER).

Island life in the Cretaceous - faunal composition, biogeography, evolution, and extinction of land-living vertebrates on the Late Cretaceous European archipelago

The Late Cretaceous was a time of tremendous global change, as the final stages of the Age of Dinosaurs were shaped by climate and sea level fluctuations and witness to marked paleogeographic and faunal changes, before the end-Cretaceous bolide impact. The terrestrial fossil record of Late Cretaceous Europe is becoming increasingly better understood, based largely on intensive fieldwork over the past two decades, promising new insights into latest Cretaceous faunal evolution. We review the terrestrial Late Cretaceous record from Europe and discuss its importance for understanding the paleogeography, ecology, evolution, and extinction of land-dwelling vertebrates. We review the major Late Cretaceous faunas from Austria, Hungary, France, Spain, Portugal, and Romania, as well as more fragmentary records from elsewhere in Europe. We discuss the paleogeographic background and history of assembly of these faunas, and argue that they are comprised of an endemic 'core' supplemented with various immigration waves. These faunas lived on an island archipelago, and we describe how this insular setting led to ecological peculiarities such as low diversity, a preponderance of primitive taxa, and marked changes in morphology (particularly body size dwarfing). We conclude by discussing the importance of the European record in understanding the end-Cretaceous extinction and show that there is no clear evidence that dinosaurs or other groups were undergoing long-term declines in Europe prior to the bolide impact.

Entre mapas e moças do tempo: informação e entretenimento na meteorologia do Jornal Nacional e do Rural Notícias

Este trabalho é um estudo sobre a mistura que se estabelece entre informação meteorológica e entretenimento nos quadros da previsão do tempo de dois telejornais nacionais das Organizações Globo: Jornal Nacional JN (canal aberto Rede Globo) e Rural Notícias RN (canal fechado Canal Rural). A recepção dos programas sobre o tempo é analisada a partir de entrevistas abertas, com 40 espectadores de ambos os noticiários, habitantes da cidade e do campo. Também por meio de entrevistas, são avaliadas as representações da produção, privilegiando as denominadas moças do tempo, Flávia Freire (JN) e Lilian Lima (RN). Auxiliam na identificação do entretenimento, nos espaços da meteorologia, a observação do surgimento do consumidor moderno, a extensão do consumo ao lazer, o divertimento pela televisão, o tempo como assunto para conversa, as representações do corpo na cultura brasileira e traços da educação na transmissão meteorológica no Telejornalismo do país. Assim, são analisados os formatos dos quadros do tempo, suas funções aparentes, formatações, imagem corporal construída de suas apresentadoras e o público-alvo de cada telejornal. Esses principais pontos são relacionados com o pensamento de autores que estudam comunicação, tempo, hedonismo, utilitarismo, consumo, representações sociais, corpo, educação e pedagogia. A previsão da meteorologia aparece com várias funções, sendo dominantes a ênfase no cotidiano, em ambos os jornais; o foco no lazer, sobretudo no Jornal Nacional; e o destaque para o vínculo com a produção rural em sentido amplo, no caso do Rural Notícias.
