“…While lower sensitivity to anthropogenic landscape features fits with their hypothesis for a generalist species and is supported by other studies of amphibians (Nowakowski et al, 2018;Pabijan et al, 2020;Pyron, 2018), Antunes et al (2022) found that local N e was significantly lower for L. vulgaris than L. montandoni. For a widespread species to show lower resistance to anthropogenic landscape features but to have less genetic connectivity compared to a range-restricted species is surprising.…”

“…Illegal logging damages ecosystems and contributes to unsustainable markets that value profit over long‐term quality and conservation of biodiversity. If forest cover has continued to diminish since the time of their sampling, findings from Antunes et al (2022) suggest these two species may have suffered local extinctions.…”

“…Investigating the landscape resistance of species is possible with individual or population‐level genomic data and publicly available satellite data to calculate land‐cover. If the sampling scheme allows, exploring connectivity via landscape genetic analysis in a manner similar to Antunes et al (2022) will compliment phylogeographical studies of species of conservation concern and help refine our understanding of the scaling relationships that influence a species resilience to habitat loss.…”

Antunes et al. (2022) present a detailed comparative landscape genetics analysis of the Carpathian Newt (Lissotriton montandoni) and the Smooth Newt (L. vulgaris; Figure 1). These close relatives are codistributed in the Carpathian Mountain Range, which includes some of the last remaining primary forests in Europe. A peculiar geographical distribution is exhibited by these species whereby the rangerestricted species, L. montandoni, is fully enclosed within the broad range of L. vulgaris, which extends from Western Europe to Western Siberia. The physiological tolerances and ecological preferences of the species restrict L. montandoni to higher elevations in closed forests or forest edges, while L. vulgaris has much broader tolerances and lower sensitivity to disturbed landscapes. It is against this ecological backdrop that the study explores how species with distinct habitat preferences respond to landscape changes.Using existing genomic resources from targeted SNP sequencing, the authors combine populations genetics (e.g. F ST , IBD and N e ) and land-cover information from satellite data to estimate genetic diversity, identify key landscape features that promote or diminish connectivity, and characterize differential responses of these species to land-cover variables at local scales. The specific populations selected for the study are scattered along a zone of secondary contact, where each has been functioning with little to no interspecific gene flow (Zieliński et al., 2019), allowing for a rare yet important replicated sampling design. Fine-scale landscape genetic analyses of these newts reinforces their differences, but also sheds light on regional sensitivities that may have been obscured in a range-wide analysis.

Comparative landscape genetics studies provide insights on the impact of landscape elements on gene flow patterns of different species inhabiting the same geographic area. We investigated the population genetic structure of two sympatric ungulates, roe deer Capreolus capreolus and Northern chamois Rupicapra rupicapra, in a mountain area of the central Italian Alps (Trentino, northern Italy). A total of 122 chamois and 72 roe deer samples were genotyped by two species-specific panels of 11 polymorphic microsatellite loci and analyzed by aspatial and spatially explicit analyses. While the roe deer population resulted unstructured, a clear population structure was detected in chamois, with two main groups, one inhabiting the eastern and the other spread in the western part of the study area. Landscape genetics analysis confirmed these scenarios and revealed a different effect of landscape on gene flow. An IBD (Isolation-By-Distance) model best explained genetic variation in roe deer, while IBR (Isolation-By-Resistance) was found as the process underlying genetic variation patterns in chamois, suggesting arable lands, coniferous forests, watercourses, and main roads as potential barriers. Species distribution and landscape use might explain these results: roe deer mostly occupy valley floors relatively connected to each other, and their spatial behavior may promote gene flow across areas. On the other hand, chamois prefer higher elevations and their movements may be hindered by valleys, rivers, and road networks. This study highlights the different impacts of natural and anthropic landscape elements on gene flow in two sympatric species, resulting from their different ecological requirements.
