Habitat Response Variability: Modeling Predictions Display the Expansion-Contraction Scenario of Two Chinese Endangered Cheirotonus Beetles Under Climate Change. [PDF]

Ecol Evol
In this paper, the Maxent model is used to predict two rare insect species of the genus Cheirotonus to understand the impact of future climate change on the suitable habitats of endangered species. The results show that the area of suitable habitats for Cheirotonus gestroi will decrease in most future scenarios, and bio3 (Isothermality), bio7 ...
