摘要: 生物多样性格局是生物地理学和保育生物学的研究重点。然而以前的研究主要关注物种多样性,忽视了遗传和功能方面。这导致对生物多样性格局的不完全揭示。以神农架南北坡的底栖动物为研究对象,分析物种多样性、分类学多样性和功能多样性的空间分布特征,探究生物多样性间的关系。结果表明,不同的底栖动物多样性对坡向因子响应不同:南坡的物种丰富度、物种均匀度和功能多样性参数变动范围明显大于北坡,而北坡的分类学多样性参数变动范围明显大于南坡;南坡的功能多样性参数的中位数明显高于北坡。显著性分析结果显示,南北坡底栖动物生物多样性无显著差异,表明局地尺度上坡向因子没能驱动生物多样性空间差异性分布。相关性分析结果显示分类学多样性和功能多样性无显著相关,生物多样性的不同面相关性较弱。研究表明,神农架底栖动物不同多样性具有差异性,在制定保护多样性策略的时候应该综合考虑生物多样性的谱系和功能方面。

Abstract: Biogeography and conservation biology focus on patterns of biodiversity. However, previous studies have interested mainly in species diversity and have almost ignored the phylogenetic and functional facets, which results in an incomplete understanding of the patterns of biodiversity. Hence, we studied the spatial pattern of multi facets of biodiversity of macroinvertebrate in Shennongjia Mountain, and examined the relationship among the species diversity, taxonomic diversity and functional diversity. Our results showed that different facets of variously responded to slope. Variation of Species richness, species evenness and functional diversity indices in south slope were greater than north, while Variation of taxonomic diversity indices in north were greater than south. Median of functional diversity indices in south were higher than north. Significance test showed that different facets of biodiversity had no remarkable difference, which indicated patterns of different facets of biodiversity were not drove by slope in local scale. Correlation analyze showed that taxonomic diversity did not significantly correlations with functional diversity, which indicate there were weak relationships in different facets of biodiversity. Our study highlighted that different facets of macroinvertebrate diversity in Shennongjia Mountain were differential, and analyzing patterns of different biodiversity facets into conservation strategies will increase its effectiveness.
