Abstract
The geographic range of New World dobsonflies (Megaloptera: Corydalidae) is studied to address the effect of the Nearctic-Neotropical transition zone on the biogeographic distribution of the species that occurred in and near the transition zone. We present potential geographic distributions based on ecological niche models for several species of dobsonflies. Our results suggest that the geographic range of dobsonflies in the transition zone is associated to mountainous formations and that most species favour warm climates with higher precipitation rates. Climate types tend to be important for species that show narrow geographic ranges, but precipitation tends to be the most important variable to explain species dispersion. Overall, our models support the dispersion of dobsonflies from the Neotropics to North America and explain the two endemic species in Mexico as the result of the formation of the transition zone.
期刊介绍：
Aquatic Insects is an international journal publishing original research on the systematics, biology, and ecology of aquatic and semi-aquatic insects.
The subject of the research is aquatic and semi-aquatic insects, comprising taxa of four primary orders, the Ephemeroptera, Odonata, Plecoptera, and Trichoptera but also aquatic and semi-aquatic families of Hemiptera, Coleoptera, and Diptera, as well as specific representatives of Hymenoptera , Lepidoptera, Mecoptera, Megaloptera , and Neuroptera that occur in lotic and lentic habitats during part of their life cycle. Studies on other aquatic Hexapoda (i.e., Collembola) will be only accepted if space permits. Papers on other aquatic Arthropoda (e.g., Crustacea) will not be considered, except for those closely related to aquatic and semi-aquatic insects (e.g., water mites as insect parasites).
The topic of the research may include a wide range of biological fields. Taxonomic revisions and descriptions of individual species will be accepted especially if additional information is included on habitat preferences, species co-existing, behavior, phenology, collecting methods, etc., that are of general interest to an international readership. Descriptions based on single specimens are discouraged.
Detailed studies on morphology, physiology, behavior, and phenology of aquatic insects in all stadia of their life cycle are welcome as well as the papers with molecular and phylogenetic analyses, especially if they discuss evolutionary processes of the biological, ecological, and faunistic formation of the group.
