Hence, it is crucial to understand the role that environmental features play in species genetic diversity and structure. Landscape genetics measures functional connectivity and evaluates the effects of landscape composition, configuration, and heterogeneity on microevolutionary processes. Deserts constitute one of the world's most widespread biomes and exhibit a striking heterogeneity of microhabitats, yet few landscape genetics studies have been performed with rodents in deserts. We evaluated the relationship between landscape and functional connectivity, at a microgeographic scale, of the Nelson's pocket mouse Chaetodipus nelsoni in the Mapimí BiosphereHeredity21-32https://www.ebi.ac.uk/biostudies/studies/S-EPMC11723970biostudies-literatureDesert landscape features influencing the microgeographic genetic structure of Nelson's pocket mouse Chaetodipus nelsoni.PMC11723970Pineda-Sanchez GVazquez-Dominguez EfalseDesert landscape features influencing the microgeographic genetic structure of Nelson's pocket mouse Chaetodipus nelsoni.Elucidating the factors that drive the genetic patterns of natural populations is key in evolutionary biology, ecology and conservation.
