The effects of autogenic-allogenic status on the species-area relationship and the relationship between geographic distance and intercommunity dissimilarity were investigated in macroparasite communities of the bluegill sunfish Lepomis macrochirus. Rank correlation analyses were used to examine the relationship between pond surface area and species richness of all species collectively and of autogenic species and allogenic species separately. A positive relationship was found for allogenic species, whereas there was no association for all species, nor was there an association when the study was restricted to autogenic species. Mantel tests were used to determine the relationship between geographic distance and community dissimilarity for all species and for autogenic and allogenic species independently. Total community dissimilarity and allogenic dissimilarity were found to be influenced by geographic distance, whereas autogenic dissimilarity was random with regard to interpond distances. These findings serve to illustrate the importance of the autogenic-allogenic dichotomy and demonstrate that dispersal ability can influence commonly observed ecological patterns.
在蓝鳃太阳鱼（Lepomis macrochirus）的大型寄生虫群落中，研究了自体-异体状态对物种-面积关系以及地理距离与群落间差异关系的影响。秩相关分析用于检验池塘表面积与所有物种总体、自体物种和异体物种的物种丰富度之间的关系。异体物种呈现出正相关关系，而所有物种之间不存在关联，当研究仅限于自体物种时也不存在关联。Mantel检验用于独立确定所有物种以及自体和异体物种的地理距离与群落差异之间的关系。发现总群落差异和异体差异受地理距离影响，而自体差异在池塘间距离方面是随机的。这些发现有助于说明自体-异体二分法的重要性，并表明扩散能力可以影响常见的生态模式。
