Combining Bayesian genetic clustering and ecological niche modeling: Insights into wolf intraspecific genetic structure
Abstract The distribution of intraspecific genetic variation and how it relates to environmental factors is of increasing interest to researchers in macroecology and biogeography. Recent studies investigated the relationships between the environment and patterns of intraspecific genetic variation ac...

Abstract The distribution of intraspecific genetic variation and how it relates to environmental factors is of increasing interest to researchers in macroecology and biogeography.
