Pesquisa de anticorpos contra Leptospira spp. em animais silvestres e em estado feral da região de Nhecolândia, Mato Grosso do Sul, Brasil. Utilização da técnica de imuno-histoquímica para detecção do agente
GIRIO, R.J.S.; PEREIRA, F.L.G.; FILHO, M.M.; MATHIAS, L.A.; HERREIRA, R.C.P.; ALESSI, A.C.; GIRIO, T.M.S. 2004. Pesquisa de anticorpos contra Leptospira spp. em animais silvestres e em estado feral da região de Nhecolândia, Mato Grosso do Sul, Brasil. Utilização da técnica de imuno-histoquímica para detecção do agente. Ciência Rural 34(1):165-169.
Abstract. Three hundred and fifteen serum samples of several animal species living in wild or in feral state in the area of Nhecolândia, Corumbá, MS, Brazil, were examined by the microscopic agglutination test. Of these samples, 67 were of feral bovine (Bos taurus indicus), 39 of feral pigs (Sus scrofa), 39 of buffaloes (Bubalus bubalis), nine of coatis (Nasua nasua), 41 of pampas deer (Ozotoceros bezoarticus), 10 of brocket deer (Mazama americana) and 110 of feral sheep (Ovis aries). In 12 dead animals (six feral pigs, four pampas deer and two feral sheep), isolation attempts and leptospira identification through the immunohistochemistry were accomplished. Sixty-four (20.3%) of the samples reacted to at least one serovar of pathogenic leptospira; 41.0% of the buffaloes, 40.3% of the feral bovine, 17.9% of the feral pigs, 9% of the feral sheep, and 9.7% of the pampas deer serum samples were reactors. All the serum samples of brocket deer and of coatis were not reactors. The most frequent serovars for the studied animal species were: pomona for buffaloes and feral sheep; icterohaemorrhagiae for feral sheep, pampas deer and feral pigs; and copenhageni for pampas deer and feral pigs. The attempts of leptospira isolation resulted negative, and the immunohistochemistry analysis revealed leptospira in the liver of one feral pig. Microscopic examination of the kidney revealed vascular congestion, hemorrhage and infiltration of mononuclear inflammatory cells in the interstice.

Camera-trap study of ocelot and other secretive mammals in the northern Pantanal
TROLLE, M.; KÉRY, M. 2005. Camera-trap study of ocelot and other secretive mammals in the northern Pantanal. Mammalia 69:3-4.
Abstract. Reliable information on abundance of the ocelot (Leopardus pardalis) is scarce. We conducted the first camera-trap study in the northern part of the Pantanal wetlands of Brazil, one of the wildlife hotspots of South America. Using capture-recapture analysis, we estimated a density of 0.112 independent individuals per km² (SE 0.069). We list other mammals recorded with camera traps and show that camera-trap placement on roads or on trails has striking effects on camera-trapping rates.

Zootaxa é
um periódico internacional para rápida publicação de artigos de alta qualidade
em qualquer aspecto da sistemática zoológica, com uma preferência por grandes
estudos taxonômicos como monografias e revisões. Zootaxa considera artigos em todos os táxons animais, vivos e
fósseis, e encoraja especialmente descrições de novos táxons. Todos os tipos de
artigos taxonômicos são considerados, incluindo teorias e métodos de
sistemática e filogenia, monografias taxonômicas, revisões e comentários,
catálogos/checklists, biografias e bibliografias, guias de identificação,
análise de características, relações filogenéticas e padrões zoogeográficos de
distribuição, descrições de táxons, e nomenclatura. A Zootaxa procura publicar cada artigo dentro de um mês após a
aceitação pelos editores.
Baseado no tamanho, os artigos podem ser
submetidos como artigos de pesquisa (research
articles) ou correspondências (correspondence).

Diet of two sympatric carnivores, Cerdocyon thous and Procyon cancrivorus, in a restinga area of Espirito Santo State, Brazil
GATTI, A.; BIANCHI, R.; ROSA, C.R.X.; MENDES, S.L. 2006. Diet of two sympatric carnivores, Cerdocyon thous and Procyon cancrivorus, in a restinga area of Espirito Santo State, Brazil. Journal of Tropical Ecology 22:227-230.
Abstract. The description of resource sharing between sympatric species can be used to determine the factors that allow species to coexist. The feeding habits of the crab-eating fox and of the raccoon were determined on the basis of scats collected. The importance of each prey type was analysed based on the frequency of its occurrence in the scats. The data suggest that the crab-eating fox and the raccoon have basically frugivorous diets, complemented by arthropods, mainly insects, and small vertebrates.

Napoleon Bonaparte and the fate of an Amazonian rat: new data on the taxonomy of Mesomys hispidus (Rodentia: Echimyidae)
ORLANDO, L.; MAUFFREY, J.-F.; CUISIN, J.; PATTON, J.L.; HÄNNI, C.; CATZEFLIS, F. 2003. Napoleon Bonaparte and the fate of an Amazonian rat: new data on the taxonomy of Mesomys hispidus (Rodentia: Echimyidae). Molecular Phylogenetics and Evolution 27:113-120.
Abstract. The spiny rat Mesomys hispidus is one of many South American rodents that lack adequate taxonomic definition. The few sampled populations of this broadly distribuuted trans-Amazonian arboreal rat have come from widely separated regions and are typically highly divergent. The holotype was described in 1817 by A.-G. Desmarest, after Napoleon's army brought it to Paris following the plunder of Lisbon in 1808; however, the locality of origin has remained unknown. Here we examine the taxonomic status of this species by direct comparison of 50 extant individuals with the holotype at the morphometric and genetic levels, the latter based on 331 bp of the mitochondrial cytochrome b gene retrieved from a small skin fragment of the holotype with ancient DNA technology. Extensive sequence divergence is present among samples of M. hispidus collected from throughout its range, from French Guiana across Amazonia to Bolivia and Peru, with at least seven mitochondrial clades recognized (average divergence of 7.7% Kimura 2-parameter distance). Sequence from the holotype is, however, only weakly divergent from those of recent samples from French Guiana. Moreover, the holotype clusters with greater that 99% posterior probability with samples from this part of Amazonia in a discriminant analysis based on 22 cranial and dental measurements. Thus, we suggest that the holotype was originally obtained in eastern Amazonia north of the Amazon River, most likely in the Brazilian state of Amapá. Despite the high level of sequence diversity and marked morphological differences in size across the range of M. hispidus, we continue to regard this assemblage as a single species until additional samples and analyses suggest otherwise.
