Previous issue date: 2010-02-22 / Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPq / We studied here the determinant factors of jaguar presence in a fragmented landscape, with
implications to design and management of ecological corridors. In the first chapter, we
evaluated the spatially structured effect of the natural preys’ richness on the jaguar occurrence
and livestock depredation, as well as the vegetation cover influence on these processes. Our
results show that jaguar occurrence is strongly determined by preys richness and the spatial
component, showing that preys’ richness raises local quality and spatial aggregation acts in a
positive way to this species. Otherwise, livestock predation, does not present a spatial
component, being directly related to predator’s abundance. For the last, we highlight the
absence of a vegetation cover effect on prey species richness and livestock depredation. In the
second chapter, we test the effect of the area and isolation of natural fragments, agriculture
intensity and spatial structure on jaguar presence. We verify that agriculture may represent a
barrier to the jaguar dispersion and the presence of a larger natural fragment among other
small patches increases the probability of jaguar presence. These results show that this species
is efficient colonizing natural vegetation patches and the stepping stones can be used in
conservation strategies to keep or reestablish connectivity in a landscape for the jaguar. / Nesse trabalho, estudamos fatores determinantes da ocorrência de onça-pintada (Panthera
onca) em uma paisagem fragmentada com implicações para o delineamento e manejo de
corredores ecológicos. No primeiro capítulo, avaliamos o efeito espacialmente estruturado da
riqueza de presas naturais sobre a ocorrência de onça-pintada e de predação dessa sobre
rebanhos bovinos, bem como a influência da cobertura vegetal sobre esses processos. Nossos
resultados mostram que a ocorrência da onça-pintada é fortemente explicada pela riqueza de
suas presas e pelo componente espacial, mostrando que a riqueza de presas aumenta a
qualidade do local e que o contágio age de forma positiva para a espécie. A predação de
rebanho doméstico, por sua vez, não possui um componente espacial significativo, estando
diretamente relacionada à abundância do predador. Por último, destacamos a ausência de
efeito da cobertura vegetal sobre a riqueza de presas e predação de rebanho doméstico. No
segundo capítulo, avaliamos o efeito do isolamento e área de fragmentos naturais, da
intensidade da agricultura e da estrutura espacial sobre a probabilidade de ocorrência da onçapintada.
Verificamos que a agricultura pode ser considerada uma barreira de dispersão para a
onça-pintada e a existência de contágio na distribuição dessa espécie. Outro resultado sugere
que a presença de pelo menos um fragmento grande além de outros menores, aumenta a
probabilidade de ocorrência da onça. Esses resultados mostram que a espécie é eficiente em
colonizar manchas de vegetação natural e que stepping stones podem ser usados em
estratégias de conservação para manter ou restabelecer conectividade em uma paisagem para
a onça-pintada.
