栖息地破坏是全世界灵长类动物面临的最大威胁之一。为了了解森林采伐对温带混交林灵长类动物栖息地利用的影响，我们比较了商业采伐前（1989年）、采伐期间（1997年）和采伐后（2002-2003年）秦岭川金丝猴（Rhinopithecus roxellana）的活动范围、栖息地利用、种群规模和种群饮食（ERT）。伐木极大地改变了森林的组成和部队的食物供应。一些地区被严重砍伐，在森林中形成缺乏树冠覆盖的斑块。伐木时，部队离开原来的活动范围7公里，停止伐木后又返回原来的活动范围，但他们避开了砍伐严重、缺乏树冠覆盖的地区。它们的运动表明该物种具有一定程度的地点保真度。伐木后饮食和活动范围发生了变化，但种群规模保持稳定，这表明该物种具有一定的适应栖息地变化的能力。我们的结果可能反映了灵长类动物适应温带地区不断变化的食物资源的天然灵活性，这些地区的食物供应和分配存在明显的季节性变化。与饮食更为特殊的热带森林灵长类动物相比，这种灵活性可能导致它们对人类活动引起的栖息地改变具有更高的适应能力。我们的研究结果提供了重要的基线信息，将帮助决策者努力保护灵长类动物，特别是在温带地区，并可持续地管理灵长类动物栖息地。
Habitat destruction is one of the greatest threats to primates worldwide. To understand the impact of forest logging on the habitat use of primates in temperate mixed forest, we compared the range, habitat used, population size, and diet of a troop (ERT) of Sichuan snub-nosed monkeys (Rhinopithecus roxellana) in the Qinling Mountains before (1989), during (1997), and after (2002-2003) commercial logging. Logging significantly changed the composition of the forest and the food supply for the troop. Some areas were heavily logged and formed patches in the forest that lacked canopy cover. The troop moved 7 km away from their original range when logging took place and returned to their original range after logging stopped, but they avoided heavily logged areas that lacked canopy cover. Their movement indicated some degree of site fidelity in this species. Diet and home range changed after logging, but the population size remained stable, which suggests that this species has some ability to adapt to habitat changes. Our results may reflect a natural flexibility in primates to adapt to the changing food resources in temperate areas with marked seasonal variations in food availability and distribution. This flexibility may have contributed to their higher degree of resilience to habitat alterations caused by human activities compared with tropical forest primates that have a more specialized diet. Our findings provide important baseline information that will help decision makers in their efforts to conserve primates, especially in temperate regions, and to sustainably manage primate habitat.
