Speciation and gene flow in two sympatric small mammals from Madagascar, Microgale fotsifotsy and M. soricoides (Mammalia: Tenrecidae)

Kathryn M Everson, Link E Olson & Steven M Goodman
Madagascar’s shrew tenrecs (Mammalia: Tenrecidae: Microgale, Nesogale) form an excellent system for studying speciation. Most species are endemic to the island’s eastern moist evergreen forest, a region renowned for high levels of biodiversity and a high rate of in situ diversification. We set out to understand the speciation dynamics in a clade of recently described taxa: Microgale fotsifotsy and M. soricoides, which have nearly identical distributions in the moist evergreen forest, and M. nasoloi, which...

Phylogenomic data reveal widespred introgression across the range of an alpine and arctic specialist

Understanding how gene flow affects population divergence and speciation remains challenging. Differentiating one evolutionary process from another can be difficult because multiple processes can produce similar patterns, and more than one process can occur simultaneously. While simple population models produce predictable results, how these processes balance in taxa with patchy distributions and complicated natural histories is less certain. These types of populations might be highly connected through migration (gene flow), but can experience stronger effects...
