Data Sheet 1_Divergent range dynamics among non-native Coleoptera: climate drivers and poleward expansion in multiple species.pdf

As temperatures rise at high latitudes, some temperate species may be shifting poleward. As non-native species expand in range they threaten native biodiversity and disrupt ecosystem functioning, making range dynamics critical to understand for effective control programs.</p>Methods<p>This study examined the dynamics of the southern geographic limit of non-native Coleoptera species in Chile.

Using occurrence data from 25 species recorded between 2007 to 2022, we evaluated how the southern range limit of each species responds to environmental variables, and whether the observed southward displacements are consistent with the regional climate trends.</p>Results<p>Model outputs provide significant evidence that the southern range limit dynamics of at least 11 species are linked to seasonal and annual fluctuations in temperature and precipitation.
