Abstract

A critical question in the conservation of large mammals in the Anthropocene is to know the extent to which they can tolerate human disturbance. Surprisingly, little quantitative data is available about large-scale effects of human activity and land use on their broad scale distribution in Europe. In this study, we quantify the relative importance of human land use and protected areas as opposed to biophysical constraints on large mammal distribution. We analyze data on large mammal distribution to quantify the relative effect of anthropogenic variables on species' distribution as opposed to biophysical constraints. We finally assess the effect of anthropogenic variables on the size of the species' niche by simulating a scenario where we assumed no anthropogenic pressure on the landscape. Results show that large mammal distribution is primarily constrained by biophysical constraints rather than anthropogenic variables. This finding offers grounds for cautious optimism concerning wildlife conservation in the Anthropocene.

摘要

在人类世保护大型哺乳动物的一个关键问题是要了解它们能够耐受人类干扰的程度。令人惊讶的是,关于人类活动和土地利用对欧洲大型哺乳动物广泛分布的大规模影响,几乎没有定量数据。在本研究中,我们量化了人类土地利用和保护区相对于生物物理限制因素对大型哺乳动物分布的相对重要性。我们分析大型哺乳动物分布数据,以量化人为变量相对于生物物理限制因素对物种分布的相对影响。最后,我们通过模拟一种假设景观不存在人为压力的情景,评估人为变量对物种生态位大小的影响。结果表明,大型哺乳动物的分布主要受生物物理限制因素而非人为变量的制约。这一发现为人类世野生动物保护带来了谨慎乐观的依据。
