摘要: 生境类型对群落多样性的影响是生态学关心的重要问题。本研究对江苏阜宁县域内农田、林地、湿地和城镇等4种生境鸟类进行为期一年的调查,从物种多样性、谱系多样性、功能多样性3个层次探究不同生境对鸟类群落的影响。共记录鸟类115种,隶属15目40科。物种多样性在林地生境最高,然后依次为农田、湿地和城镇生境。谱系多样性和功能多样性与物种多样性变化模式不同,农田生境的谱系和功能多样性较其他3种生境高。比较分析生境间3种多样性指标的季节变化,发现多样性指标在季节间无显著性差异,阜宁县域内鸟类群落多样性受生境影响较大。标准化效应值分析表明,各生境群落谱系和功能多样性均呈现出聚集趋势,生境过滤主导鸟类群落的构建。本研究揭示了阜宁县域范围内鸟类资源现状,环境异质性维持较高的鸟类多样性,生境类型的多样化为保持高的鸟类群落多样性提供有力支持。

Abstract: The effect of habitat type on community diversity is a fundamental concern in ecology. In this study, we estimated taxonomic, functional, and phylogenetic diversity of bird community in four habitats (farmland, woodland, wetland, and urban area) in Funing County, Jiangsu Province in 2018-2019. A total of 115 species belonging to 15 orders and 40 families were recorded. Woodland had the highest value of taxonomic diversity, followed by farmland, wetland, and urban area. However, farmland showed the highest values of phylogenetic and functional diversity. There was no seasonal variation in bird diversity. Habitat type was more important than season in shaping bird community diversity. Standard effect size of each phylogenetic and functional diversity metrics in different habitats was significantly less than zero, indicating that environmental filtering was the main driver of bird community assembly. With comprehensive multi-dimensional diversity analysis, our results indicated that environmental heterogeneity help maintain high bird diversity and the diverse habitats provide strong support for high bird community diversity.
