土地利用变化是物种灭绝危机的根本原因，但栖息地变化与生物多样性丧失之间的联系尚未得到充分了解。虽然有证据表明栖息地丧失是一个重要的灭绝驱动因素，但栖息地破碎化的相关性仍存在争议。此外，虽然生物多样性对栖息地转变的响应的时间延迟已经得到了充分的记录，但在栖息地丧失与破碎化的争论中，时间延迟效应被忽视了。本文采用贝叶斯多物种占用框架，系统地测试了鸟类和哺乳动物群落对栖息地丧失和栖息地破碎化的时滞响应。我们关注的是阿根廷的查科，那里的森林砍伐最近很普遍。我们使用了广泛的鸟类和哺乳动物野外数据集，以及1985年至2016年覆盖近期和历史栖息地变化的年度林地地图时间序列。当代栖息地数量比过去的栖息地数量更能解释鸟类和哺乳动物的占用情况。然而，占用率更多地受到过去而不是最近的碎片化的影响，这表明对碎片化的反应是时滞的。因此，考虑过去的景观格局对于理解当前的生物多样性格局至关重要。不考虑土地利用历史忽略了灭绝债务的可能性，从而模糊了破碎化的影响，潜在地解释了栖息地丧失与破碎化研究的对比结果。
Land-use change is a root cause of the extinction crisis, but links between habitat change and biodiversity loss are not fully understood. While there is evidence that habitat loss is an important extinction driver, the relevance of habitat fragmentation remains debated. Moreover, while time delays of biodiversity responses to habitat transformation are well-documented, time-delayed effects have been ignored in the habitat loss versus fragmentation debate. Here, using a hierarchical Bayesian multi-species occupancy framework, we systematically tested for time-delayed responses of bird and mammal communities to habitat loss and to habitat fragmentation. We focused on the Argentine Chaco, where deforestation has been widespread recently. We used an extensive field dataset on birds and mammals, along with a time series of annual woodland maps from 1985 to 2016 covering recent and historical habitat transformations. Contemporary habitat amount explained bird and mammal occupancy better than past habitat amount. However, occupancy was affected more by the past rather than recent fragmentation, indicating a time-delayed response to fragmentation. Considering past landscape patterns is therefore crucial for understanding current biodiversity patterns. Not accounting for land-use history ignores the possibility of extinction debt and can thus obscure impacts of fragmentation, potentially explaining contrasting findings of habitat loss versus fragmentation studies.
