广西弄岗喀斯特森林繁殖鸟群落的集团结构

Guild structure of forest breeding bird community in Nonggang Nature Reserve of Guangxi

  • 摘要: 于2010、2011和2012年5—7月在广西弄岗国家级自然保护区对喀斯特森林繁殖鸟类群落的集团结构进行了研究。对44种繁殖鸟类的取食方式、取食基层和取食高度进行聚类分析和主成分分析。其结果如下:(1)鸟类群落可分为6个取食集团,分别为地面取食集团、下层取食集团、上层取食集团、多层取食集团、树干取食集团和空中出击集团;(2)与其他森林类型的鸟类群落集团结构相比,喀斯特季节性雨林的鸟类群落以中、下层取食鸟类为主,多层取食集团次之。其原因可能是:弄岗喀斯特森林植被结构和鸟类食性特点形成了中下层取食的鸟类种数占优势的现象;鸟类以扩展各自生态位宽度方式来缓解竞争压力,从而形成了多层取食集团这一特点。

     

    Abstract: Surveys about the breeding bird guild structure in karst forest of Nonggang Nature Reserve, Guangxi Zhuang Autonomous Region, were conducted successively in May-July 2010, 2011 and 2012. The feeding modes, foraging strata and foraging heights of 44 breeding bird species were analyzed by clustering and principal component method. The results indicated that the avian community could be divided into 6 guilds, including ground feeding guild, lower feeding guild, upper feeding guild, multilayer feeding guild, trunk feeding guild and air strike guild. Depending on the vegetation structure of Nonggang karst forest and feeding habits, middle layer, lower layer and multilayer feeding guilds were dominant in the karst monsoon forest. Data suggests that the birds tried to alleviate competition pressures by increasing niche breadth, so multilayer feeding guild was formed.
