Abstract

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.

Highlights

The shape of the species occupancy frequency distribution (SOFD) and a positive species abundance–occupancy relationship (SAOR) are two widely studied patterns within community ecology
We found no differences in the species occupancy frequency distributions (SOFD) patterns between temporal and permanent water bodies (Table 2; Figure 3)
Our results show that a unimodal satellite-dominant SOFD pattern and a positive SAOR pattern are prevalent in the Pampa communities, both in temporary and permanent water bodies

Summary

Introduction

The shape of the species occupancy frequency distribution (SOFD) and a positive species abundance–occupancy relationship (SAOR) are two widely studied patterns within community ecology (see reviews by Gaston et al, 1997, 2000; Jenkins, 2011; McGeoch & Gaston, 2002). There are two common models, which explain the SOFD (Jenkins, 2011; McGeoch & Gaston, 2002) and positive SAOR (Gaston et al, 1997; Gaston et al, 2000) patterns: (a) the metapopulation dynamic model (hereafter MPDM; Hanski, 1982; Hanski, 1999) and (b) the niche-based model (hereafter NBM; Brown, 1984). In the case of aquatic communities, the support for this pattern is relatively weak (Verberk, van der Velde, & Esselink, 2010; Heino, 2015; but see Korkeamäki, Elo, Sahlén, Salmela, & Suhonen, 2018)
