In a two-year field study across 58 isolated wetlands in Texas (USA), we examined whether odonate (Insecta: Odonata) assemblages were structured by local environmental filters or instead simply reflected the use of any available water this semi-arid region. Cluster analysis resolved three wetland groupings based on characteristics (hydroperiod, chemistry, vegetation); 37 species detected at these wetlands. The most speciose occurred with longer hydroperiods; sites also had found no other type. Ordination plots indicated some filtering respect to hydroperiod, but there was only mixed weak support factors. Because persistence strongest driver maintaining diversity region, regardless quality vegetation, beggars cannot be choosers system and conservation efforts can focus maintenance supplementation.
