两个鸟类混合群系统中有关捕食风险的社会信息

发布时间：2022-12-18 17:14

　　研究背景和目的理解物种的种间关系及其影响因子是探究群落集合中非常关键的内容,同时在制定群落保护计划上有重要的实践意义。鸟类混合群（Mixedspecies flocks of birds）和鸟类围攻猛禽时形成集群是陆地森林中尤为常见鸟类集群。由于许多物种参与混合群和猛禽围攻,所以这两种集群是研究鸟类群落中物种相互作用的模式系统。鸟类混合群中一些物种被认为是“核心种”（nuclear species）,是社会信息（social information）的主要提供者,而其他物种（跟随种,follower species）则利用这些信息来提高觅食效率和减少捕食风险。目前,这种“核心种-跟随种”关系如何响应不同捕食风险尚缺乏认识;此外,鸟类混合群和围攻时形成的集合会随着季节改变,目前尚不清楚这种季节变化是如何影响信息的产生和物种的角色的;最后,“核心种-跟随种”关系研究内容主要集中在警戒叫声和围攻叫声,目前还没有研究表明跟随物种是否会利用核心种的联络叫声来减少捕食风险。基于此,本研究探索了三个关键问题:1)不同捕食风险的社会信息是否与混合群中的角色（核心种和跟随种）相关,以及是否受到季节的影响...
