ABSTRACT: Oecomys cleberi is an arboreal rodent little known reagarding its natural history, distribution, and ecology. In this paper, we present new records of O. cleberi within a region of the Atlantic Forest, in a transition zone with Cerrado, in the northwestern state of São Paulo. We investigated the effects of the structure of fragmented landscapes on its occurrence at 40 sites in this region. We detected O. cleberi only in seasonal semideciduous forests and palm forests, but not in pastures, wetlands, and young reforestation. Our results indicated that its occurrence was determined by the amount of habitat within a 500 m radius landscape, and extremely low occupancy probabilities in landscapes with less than 25% forest cover (ψ < 0.3). Our results show the importance of the amount of habitat at the landscape scale for the occurrence of Oecomys cleberi, and point out that most of the landscapes in the study region presented low occupancy probabilities by this forest rodent. Although O. cleberi should not be considered as an Atlantic Forest species, it seems to be a resident species in ecotone areas with Cerrado, within the Atlantic Forest domain. Thus, conservation actions are necessary to preserve their populations in these regions. RESUMO: Oecomys cleberi é um roedor arbóreo com aspectos de sua história natural, distribuição e ecologia ainda pouco conhecidos. Neste artigo, apresentamos novos registros de O. cleberi em uma região de ecótone da Mata Atlântica com Cerrado, no noroeste do estado de São Paulo e investigamos os efeitos da estrutura da paisagem em sua ocorrência em 40 locais nesta região. Nós detectamos O. cleberi apenas em floresta estacional semidecidual e floresta de palmeiras, mas não em pastagens,várzea e reflorestamento jovem. Nossos resultados indicam que sua ocorrência foi determinada pela quantidade de floresta em paisagens de 500 m de raio e probabilidades de ocupação extremamente baixas em paisagens com menos de 25% de cobertura florestal (ψ < 0.3). Nossos resultados mostram a importância da quantidade de habitat na escala da paisagem para a ocorrência de O. cleberi e apontaram que a maioria das paisagens da região de estudo apresentaram baixas probabilidades de ocupação por esse roedor. Ainda que O. cleberi não possa ser considerada uma espécie da Mata Atlântica, ele parece ser uma espécie residente em áreas de ecótone com Cerrado, dentro do domínio da Mata Atlântica. Assim, ações de conservação são necessárias para preservar suas populações nessas regiões.

Assessing the impact/adaptation of human activities on/to climate change is a key issue, especially in the tropics that concentrate major anthropogenic dynamics such as deforestation and nearly two-thirds of the planetary rainfall. However, this task is often made tough because human activities such as agricultural dynamics are usually analysed at local or regional scale whereas climate related studies are led at large to global scales due to a lack of reliable data, especially in the tropics. In this article we argue that the increased spatial resolution of remote sensing-based rainfall estimates enables assessing the spatiotemporal variability of rainfall regimes at regional and local scales, thus allowing fine analysis of the interactions with human activities. We processed Tropical Rainfall Measuring Mission (TRMM) 3B42 daily rainfall estimates over the state of Mato Grosso (southern Brazilian Amazon) for the 1998-2012 study period in order to compute rainfall metrics such as annual rainfall and duration, onset and end dates of the rainy season based on the Anomalous Accumulation methodology (at a 0.25 degrees spatial resolution). We then crossed these metrics with agricultural maps (produced at a 250m spatial resolution) and proved that the adoption of intensive agricultural practices such as double cropping systems is partly the result of a strategy to adapt practices to local climatic conditions. Finally, we discuss how such results raise important issues regarding the sustainability of the agricultural development model in the Southern Amazon.
