Incidental catch of South American sea lion in a pair trawl off southern Brazil

MACHADO, R.; OLIVEIRA, L.R.; MONTEALEGRE-QUIJANO, S. 2015. Incidental catch of South American sea lion in a pair trawl off southern Brazil. Neotropical Biology and Conservation 10(1):43-47. doi: 10.4013/nbc.2015.101.06

Abstract. The population of the South American sea lion, Otaria flavescens (Shaw, 1800), in Uruguay is declining at an annual rate of 1.6 to 2.0%. Although the reasons are still unknown, interactions with fishing activities have been identified as a major cause. The individuals that arrive along the coast of Brazil come from the breeding colonies off Uruguay after their breeding period. We report here the first record of incidental catch of South American sea lions in Brazilian waters by a pair trawl. On July 17th, 2008 a young male of South American sea lion was incidentally caught during a commercial pair trawl fishing trip along the southern Brazilian coast (32º57’S, 52º31’W), in a depth ranging from 15 to 20 m. Despite being punctual, this record is an evidence of a potential major threat to South American sea lions in southern Brazil and Uruguay, since trawl industrial fishing is a very important economic activity in South Brazil.

First record of the bushy-tailed opossum, Glironia venusta, Thomas, 1912, (Didelphimorphia) from Manaus, Amazonas, Brazil

CALZADA, J.; DELIBES, M.; KELLER, C.; PALOMARES, F.; MAGNUSSON, W. 2008. First record of the bushy-tailed opossum, Glironia venusta, Thomas, 1912, (Didelphimorphia) from Manaus, Amazonas, Brazil. Acta Amazonica 38(4):807-810.

Abstract. A new record of a very rarely observed mammal, the bushy-tailed opossum, Glironia venusta (Didelphimorphia), was obtained for the Adolpho Ducke Forest Reserve, Manaus, Amazonas state, Brazil. Only 17 other records existed of this species, most from the 1980s. There were only three previous records of the species from Brazil (in the states of Pará, Amazonas and Rondônia). This new record supports the notion that G. venusta is a locally rare species throughout its range, but widely distributed in Brazilian Amazonia.

Plant Ecology publica artigos científicos originais que reportam e interpretam os achados de pesquisas puras e aplicadas na ecologia de plantas vasculares nos ecossistemas terrestres e pântanos. Artigos empíricos, experimentais, teóricos e de revisão reportando ecologia ecofisiologia, população, comunidade, ecossistema, paisagem, molecular e histórica estão no escopo do periódico.

O periódico publica Artigos de Pesquisa (Research Papers) e Cartas de Pesquisa (Research Letters), revisões e fascículos especiais por submissão e por convite. Longas monografias podem ser aceitas pelo Editor-Chefe se um caso é feito pelos autores em relação a trabalhos de alta qualidade. Comunicações de Pesquisa (Research Communications) podem reportar sobre qualquer área no escopo do periódico, mas são particularmente procurados em relação a questões tópicas em ecologia vegetal, especialmente no que concerne à teoria e metodologia. O periódico não publica revisões de livros.

Embora Plant Ecology seja um periódico de ecologia vegetal, ele também aceita artigos de interação animal-planta, e por isso algumas vezes pode ser procurado por mastozoólogos.

Perceptions of human-carnivore conflicts in the High Andes of Argentina

LUCHERINI, M.; MERINO, M.J. 2008. Perceptions of human-carnivore conflicts in the High Andes of Argentina. Mountain Research and Development 28(1):81-85. DOI: http://dx.doi.org/10.1659/mrd.0903

Abstract. The Andean cat (Leopardus jacobitus), one of the world’s most threatened felids, forms part of the little known carnivore guild occurring in the dry areas of the High Andes. Although human–carnivore conflicts are among the major causes of carnivore population decline, no data are available on this issue for the High Andes. We report here the results of the first survey of human perceptions of, and attitudes towards, carnivores in the high-altitude Andes of Argentina. Interviews with 50 adults and 226 schoolchildren revealed that pumas (Puma concolor) and foxes (Lycalopex culpaeus) are considered pests for preying upon livestock and are actively hunted by adults. Although perceptions of the Andean cat and the Pampas cat (Leopardus colocolo) were more positive, especially among schoolchildren, they are also frequently killed by local people. We suggest that, contrary to what was previously thought, hunting might be affecting the conservation status of the Andean cat and of some puma populations in the High Andes of Argentina, and that education strategies may help to improve human attitudes, particularly in the case of the endangered Andean cat.

Niche separation between the maned wolf (Chrysocyon brachyurus), the crab-eating fox (Dusicyon thous) and the hoary fox (Dusicyon vetulus) in central Brazil

JÁCOMO, A.T.A.; SILVEIRA, L.; DINIZ-FILHO, J.A.F. 2004. Niche separation between the maned wolf (Chrysocyon brachyurus), the crab-eating fox (Dusicyon thous) and the hoary fox (Dusicyon vetulus) in central Brazil. Journal of Zoology, London 262:99-106. DOI:10.1017/S0952836903004473

Abstract. Four species of canids occur in the Cerrado of central Brazil. Three of them, the maned wolf Chrysocyon brachyurus, the crab-eating fox Dusicyon thous and the hoary fox Dusicyon vetulus, were studied in Emas National Park between 1996 and 1999 to investigate niche separation. The diet of the three species was studied to understand niche breadth and degree of overlap. Habitat and activity patterns were used as second and third ecological parameters to define niche dimensions, and were estimated using camera-trap data. The maned wolf is the largest species, weighing c. 21 kg, and is about three times larger than the crab-eating fox and six times larger than the hoary fox. The major ecological differences between the three species were found in their food niche and habitat use, where crab-eating fox presented higher differences from the hoary fox (Pianka’s index of niche overlap (O) = 0.405). Despite differences in niche breadth, habitat use between the hoary fox and the maned wolf were more similar, explaining their larger overlap, in comparison with habitat use by the crab-eating fox. Activity patterns among the species showed less divergence. The three species presented two activity peaks, one in the dusk–night period and another in the morning period. These data permit a better understanding of the ecological separation of the three Cerrado canids that enables their coexistence.
