Odonate species occupancy frequency distribution and abundance–occupancy relationship patterns in temporal and permanent water bodies in a subtropical area

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
In this paper, we explore species richness, species occupancy frequency distributions (SOFD), and abundance–occupancy relationship (SAOR) patterns of dragonflies (Odonata) in a neotropical subtropical grassland area, especially addressing differences between permanent and temporal water bodies. We were able to show that both types of water bodies had odonate assemblages which fitted best with the unimodal satellite SOFD pattern while 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. This is to our knowledge, the first time SOFD and SAOR patterns are tested for aquatic invertebrates in a subtropical area.
