Quaternary Habitat Fluctuations and Demographic Dynamics in Turtles Inferred From Environmental Niche Modelling and Whole Genome Data.

ABSTRACT: Quaternary climatic fluctuations had a substantial influence on ecosystems, species distribution, phenology and genetic diversity, driving extinction, adaptation and demographic shifts during glacial periods and postglacial expansions. Integration of genomic data and environmental niche modelling can provide valuable insights on how organisms responded to past environmental variations and contribute to assessing vulnerability and resilience to ongoing climatic challenges. Among vertebrates, turtles are particularly vulnerable to habitat changes because of distinctive life history traits and the effect of environmental conditions on physiology and survival. We estimated contemporary heterozygosity (H) and effective population size (N_e) using a high-quality chromosome-level refere
