关于丰富模式的研究,圣地亚哥多明古洛的Odonata的多样性和丰度,瓦哈卡在这里介绍。共有六个家族的1601个标本,通过每月5天的采样获得26属50种。Libellulidae是最多样化的家族(21种),其次是Coenagrionidae(19),Gomphidae(4)和Calopterygidae(3)。TheLestidae,盘科和七科种类较少,每个物种只有一个。Argia是最特殊的属,有11种,其次是Enallagma,Hetaerina,红藻和巨藻各有三种,以及Phyllogomphoides,Brechmorhoga,Dythemis,红斑和Orthemis各有两种。其余17个属各有一个物种。ArgiapipilaCalvert,1907年和Selys的LeptobasisvacillansHagen,1877年是瓦哈卡州的第一次记录。我们还分析了SantiagoDominguilloOdonata组合的分类学和系统发育差异的时间模式:全年的Shannon多样性值为21.07有效物种,而辛普森的多样性是13.17。总的来说,每月的系统发育差异高于预期的分类学差异,和较小的平均分类清晰度。每月的多样性,均匀度和分类差异与月降水量值呈显着正相关(从中等到强)。对我们结果的分析,然而,表明降雨量的增加不仅影响物种的时间多样性,以及构成这些时间组合的超特定分类群的身份,即时间系统发育差异增加。
A study on the patterns of richness, diversity and abundance of the Odonata from Santiago Dominguillo, Oaxaca is presented here. A total of 1601 specimens from six families, 26 genera and 50 species were obtained through monthly samplings of five days each. Libellulidae was the most diverse family (21 species), followed by Coenagrionidae (19), Gomphidae (4) and Calopterygidae (3). The Lestidae, Platystictidae and Aeshnidae families were the less diverse, with only one species each. Argia was the most speciose genus with 11 species, followed by Enallagma, Hetaerina, Erythrodiplax and Macrothemis with three species each and Phyllogomphoides, Brechmorhoga, Dythemis, Erythemis and Orthemis with two species each. The remaining 17 genera had one species each. Argia pipila Calvert, 1907 and Leptobasis vacillans Hagen in Selys, 1877 were recorded for the first time for the state of Oaxaca. We also analysed the temporal patterns of taxonomic and phylogenetic divergence for the Santiago Dominguillo Odonata assemblage: the Shannon diversity value throughout the year was 21.07 effective species, while the Simpson diversity was 13.17. In general, the monthly phylogenetic divergence was higher than expected for taxonomic distinctness, and lesser for average taxonomic distinctness. Monthly diversity, evenness and taxonomic divergence showed significant positive correlations (from moderate to strong) with monthly precipitation values. The analysis of our results, however, indicates that an increase in rainfall not only influences the temporal diversity of species, but also the identity of supraspecific taxa that constitute those temporal assemblages, i.e. there is an increase in temporal phylogenetic divergence.
