Climate change can have a variable number of effects on different species, even closely-related species. In the present study, I use Maxent
, a machine-learning species distribution software, to predict the future ranges of two closely-related ambush bug species found in overlapping distributions, P. americana and P. pennsylvanica. The results provide evidence for species-specific environmental requirements and highlight the effects of climate change on range shifts. Understanding how these abiotic factors affect ambush bug distributions will be fundamental for future research on their taxonomy and conservation.
