Using the ecological relationships of Odonata with a habitat integrity index to test the biodiversity ecosystem function framework

As a result of human activities causing changes to their environments, many species are facing an increased risk of extinction. In order to determine such changes and their effects on species assemblages, rapid stream assessment techniques of environmental analysis and monitoring can be used. We determined the Habitat Integrity Index (HII) and its correlation with the composition and assemblage of adult odonates at different taxonomic levels in the region of the Selva Lacandona, Chiapas in southeastern Mexico. Both suborders Zygoptera and Anisoptera, the family Coenagrionidae, and the assemblage of 20 species of the genera Argia , Cora , Hetaerina , and Heteragrion (ACHH) were related with the HII. All taxonomic levels were included in the analyses as predictors of habitat integrity. However, we hypothesized that the abundance, species richness, and diversity of stenotopic species (ACHH) could be a better predictor of the HII than the other taxonomic levels. We found a positive and statistically significant relationship between the HII and the ACHH species, richness, and diversity. In contrast, we found a negative and significant relationship between HII and Anisoptera species, abundance, richness and diversity. Implications for insect conservation This study has implications for insect conservation: in this case, the protected area hosts more specialist species than the surrounding zone. For example, Ejido El Tumbo, which presents a severe level of disturbance and is outside of protected natural areas, has the lowest species diversity of all sites. We recommend further research to determine the link between disturbance and the prevalence of stenotopic species.
