  • Note di contenuto: Spatial genetic structure () is largely determined by colonization history, landscape and ecological characteristics of the species. Therefore, sympatric and ecologically similar species are expected to exhibit similar s, potentially enabling prediction of the of one species from that of another. On the other hand, due to interspecific interactions, ecologically similar species could have different s. We explored the s of the closely related and within inland and related the genetic patterns to characteristics of the sampling localities. We observed different s for the two species. Genetic differentiation even within short distances in suggests genetic drift as an important driver. However, we also observed indication of previous gene flow (revealed by a negative relationship between genetic differentiation and increasing potential connectivity of the landscape). Interestingly, genetic diversity of was negatively related to density of suggesting that interspecific interactions influence the of . In contrast, genetic differentiation between subpopulations was low and only exhibited relationships with latitude, pointing to high gene flow, colonization history and range margin effects as the drivers of . The different s of the two ecologically similar species caution indirect inferences of based on ecologically similar surrogate species.
