Relative importance of environment, human activity and spatial situation in determining the distribution of terrestrial mammal diversity in Argentina

We recorded the number of terrestrial mammal species in each Argentinian province, and the number of species belonging to particular groups (Marsupialia, Placentaria, and among the latter, Xenarthra, Carnivora, Ungulates and Rodentia). We performed multiple regressions of each group’s SR on environmental, human and spatial variables, to determine the amounts of variation explained by these factors. We then used a variance partitioning procedure to specify which proportion of the variation in SR is explained by each of the three factors exclusively and which proportions are attributable to interactions between factors.

Medicina de espécies zoológicas

O presente relatório refere-se ao estágio curricular realizado no Badoca Safari Park, no âmbito do mestrado integrado em medicina veterinária da Universidade de Évora, na área de medicina de espécies zoológicas Este encontra-se dividido em duas partes, uma relativa às atividades realizadas e casuística, acompanhada de aprofundamento teórico, e outra relacionada com a pesquisa de hemoparasitas em ungulados, através de esfregaços sanguíneos, efetuada no decorrer do estágio. As hemoparasitoses são infeções com potencial zoonótico, transmitidas por vetores, associadas a importantes perdas económicas. O controlo destas afeções tem como obstáculos fatores económicos e sociais, a heterogenicidade de hospedeiros que estes hemoparasitas e respetivos vetores apresentam, assim como o facto das espécies de animais selvagens poderem atuar como hospedeiros reservatórios. A entrada de animais exóticos e saída de autóctones, em zonas endémicas, provoca desequilíbrios na relação entre o parasita e hospedeiro que poderão despoletar episódios de doença; Abstract: Zoo and Wildlife medicine This report refers to the internship held at Badoca Safari Park, as part of the integrated master’s degree in veterinary medicine, at the University of Évora, in the clinic area of wild species and wild animals. This thesis is devided into two parts, one on the activities and cases, accompanied by theoretical studies, and the other related to hemoparasites research on ungulates through blood smears, performed during the intership. The hemoparasitoses are infections with zoonotic potential, transmited by vectors associated with significant economic losses. The control of these affections has as main obstacles the economic and social factors, the heterogeneity of hosts these hemoparasites and respective vectors present, as well as the fact that the wildlife species can act as reservoir hosts. The entry of exotic animals and the disappearance of natives, in endemic areas, causes imbalances in the relationship between parasite and host that can trigger episodes of illness.
