We assessed the species-specific response of 14 arboreal and ground mammals to landscape-scale forest loss and fragmentation measured across different scales in the Lacandon rainforest, Mexico. Most species (6 of 14 species, 43%) were weakly related to forest loss, or positively associated with it (7 of 14, 50%), likely because in this young agricultural frontier some individuals can crowd in the remaining forest patches. Only the Geoffroy’s spider monkey was negatively impacted by forest loss. We did not find evidence of extinction thresholds (nonlinear responses to forest loss) in any species. Only in four species fragmentation <i>per se</i> provided a slightly better fit to the data, but its effect was non-significant. Our multiscale analysis revealed that the scale of effect of forest loss and fragmentation was independent of body mass and habitat use (arboreal vs. ground).

本研究针对墨西哥拉坎顿热带雨林（Lacandon Rainforest）内的14种树栖与陆生哺乳动物，评估了其对以不同空间尺度量化的景观尺度森林丧失与片段化的物种特异性响应。结果显示，14个物种中有6种（占比43%）与森林丧失呈弱相关，另有7种（占比50%）与之呈正相关，这一现象可能源于该新兴农业垦殖前沿中，部分个体可聚集于残存的森林斑块内。仅杰弗洛伊蜘蛛猴（Geoffroy’s Spider Monkey）受到森林丧失的负面影响。本研究未在任何物种中发现灭绝阈值（即对森林丧失的非线性响应）的相关证据。仅在4个物种中，片段化本身（per se）对数据的拟合度稍优，但其效应并不显著。多尺度分析结果表明，森林丧失与片段化的效应尺度与物种体重及栖息地利用类型（树栖 vs. 陆生）相互独立。
