Small mammals in high fragmented landscape in Cerrado/Atlantic Forest ecotone, Southeastern Brazil

ABSTRACT Exploratory human activities have resulted in small fragments inserted into a matrix which is inhospitable to small non-flying mammals. The effects of landscape changes alter the distribution patterns of species. Landscape fragmentation patterns for small mammals are controversial, especially considering small fragments and ecotonal regions. Based on these arguments, we investigated the diversity patterns of small mammals in small fragments in the ecotonal Cerrado/Atlantic Forest region. A total of 24 fragments (摘要：人类探索性活动使得小型非飞行哺乳动物难以生存的基质中嵌入了小型生境片段。景观变化带来的效应会改变物种的分布格局。当前针对小型哺乳动物的景观破碎化格局尚存争议，尤其是在涉及小型生境片段与生态交错区域的场景下。基于上述争议，我们针对塞拉多/大西洋森林生态交错带（ecotonal Cerrado/Atlantic Forest region）内的小型生境片段中的小型哺乳动物多样性格局开展了调查研究。本次调查共纳入24个生境片段（
