This paper investigates species richness and species occupancy frequency distributions (SOFD) as well as patterns of abundance–occupancy relationship (SAOR) in Odonata (dragonflies and damselflies) in a subtropical area. A total of 82 species and 1983 individuals were noted from 73 permanent and temporal water bodies (lakes and ponds) in the Pampa biome in southern Brazil. Odonate species occupancy ranged from 1 to 54. There were few widely distributed generalist species and several specialist species with a restricted distribution. About 70% of the species occurred in <10% of the water bodies, yielding a surprisingly high number of rare species, often making up the majority of the communities. No difference in species richness was found between temporal and permanent water bodies. Both temporal and permanent water bodies had odonate assemblages that fitted best with the unimodal satellite SOFD pattern. It seems that unimodal satellite SOFD pattern frequently occurred in the aquatic habitats. The SAOR pattern was positive and did not differ between permanent and temporal water bodies. Our results are consistent with a niche‐based model rather than a metapopulation dynamic model.

亚热带地区暂时性和永久性水体中的蜻蜓物种占用频率分布和丰度-占用关系模式。
本文研究了亚热带地区蜻蜓目（蜻蜓和豆娘）的物种丰富度和物种占用频率分布（SOFD）以及丰度-占用关系（SAOR）模式。在巴西南部潘帕生物群落的 73 个永久和临时水体（湖泊和池塘）中，总共发现了 82 个物种和 1983 个个体。蜻蜓类物种占据范围为 1 至 54。广泛分布的通才物种很少，分布有限的特殊物种也很少。大约 70% 的物种出现在 <10% 的水体中，稀有物种的数量惊人地多，通常构成了群落的大多数。临时水体和永久水体之间没有发现物种丰富度差异。临时水体和永久水体都具有最适合单峰卫星 SOFD 模式的奥酸盐组合。看来单峰卫星 SOFD 模式经常出现在水生生境中。 SAOR 模式为正，并且永久水体和临时水体之间没有差异。我们的结果与基于利基的模型而不是复合种群动态模型一致。
