Why do bugs perish? Range size and local vulnerability traits as surrogates of Odonata extinction risk

open access: yesProceedings of the Royal Society B, 2020
Despite claims of an insect decline worldwide, our understanding of extinction risk in insects is incomplete. Using bionomic data of all odonate (603 dragonflies and damselflies) North American species, we assessed (i) regional extinction risk and ...

Predicting the distributions of under-recorded Odonata using species distribution models [PDF]

open access: yes, 2012
1. Absences in distributional data may result either from the true absence of a species or from a false absence due to lack of recording effort. I use general linear models (GLMs) and species distribution models (SDMs) to investigate this problem in ...
