Using species distribution models to locate animal aggregations : a case study with Hippodamia undecimnotata (Schneider) overwintering aggregation sites [Ecological Entomology]

1. The protection of animals’ aggregation sites is increasingly seen as a key conservation strategy. However, to efficiently protect aggregation sites, they need to be accurately located. Species distribution models (SDMs) are an important tool in biological conservation to predict spatial distribution of species and they are used here to predict the distribution of the aggregation sites of a ladybird (Coleoptera : Coccinellidae) species.
2. Hippodamia undecimnotata forms spectacular overwintering aggregations at the same locations every year across southern and eastern Europe. In this study, an SDM was developed and its performance tested for H. undecimnotata aggregations in southwest France. Moreover, the study looked at how environmental variables correlate with ladybirds’ abundance in the aggregation sites.(...)
