摘要
从2005年11月5日至2006年1月21日,为了评估小麂和野猪的生境选择及其差异,我们在浙江清凉峰国家级自然保护区核心区共设置了248个样方群。研究发现,两者都选择平缓坡的灌丛植被、草本密度小、离住宅较近和离隐蔽物距离适中的生境,表现了它们的生境选择有一定的重叠性。但是它们也表现出生境选择的一些差异,小麂选择乔木密度适中、灌丛密度大和郁闭度适中的生境,而野猪选择乔木密度小的生境,随机地使用各类灌丛密度和郁闭度的生境。小麂还选择北坡、离水源距离较远的生境,野猪只是随机地使用不同的坡向和离水源距离的生境。分析两者共存的机制,我们发现小麂采取隐藏策略而野猪采取逃跑策略来避敌和利用资源,即它们之间存在与反捕食策略相关的生境选择差异。
We studied habitat selection of Reeves＇s muntjacs （Muntiacus reevesi） and wild boars （Sus scrofa） in Qingliangfeng Nature Reserve in northwestern Zhejiang, China. Habitat characteristics were measured on the basis of expected differences between species at 248 sites from 5 November 2005 to 21 January 2006. Habitat selection showed a certain extent of overlap, muntjacs and wild boars both selected habitats with shrub vegetation, low herbage density, gentle slopes, relatively close to residences, and moderate concealment. Differences in habitat selection were that muntjacs selected habitats with moderate tree density, greater shrub density and moderate canopy, whereas wild boars selected habitats with lower tree density. Muntjacs selected north-facing slopes and habitats distant from water-sources, whereas wild boars displayed no selection with regard to slope or distance from water sources. We suggest that the two species coexist in Qingliangfeng as a result of differential habitat selection associated with their species-specific anti-predator strategies. Muntjacs avoid predators by concealment whereas wild boars evade predators by running as their escape strategy.
