Although turtles are the most threatened taxonomic group within the reptile class, we have a very limited understanding of how turtles respond to climate change. Here, we evaluated the effects of climate changes on the geographical distribution of Caspian pond turtle (Mauremys caspica). We used an ensemble approach by combining six species distribution models including artificial neural network...
The western pond turtle Emys (formerly Clemmys) marmorata is declining throughout its range, primarily due to loss of habitat via urbanization and conversion to agriculture. Urban waterways present several important challenges to freshwater turtle populations, but they also present an opportunity to maintain declining species in a ubiquitous habitat that has high public visibility. The arboretu...
The historical biogeography of California's taxa has been the focus of extensive research effort. The western pond turtle (Emys marmorata) is an example of a wide-ranging taxon that spans several well-known California diversity hotspots. Using a dataset comprised of one mitochondrial and five nuclear loci, we elucidate the major biogeographic patterns of the western pond turtle across the Calif...
a widely distributed species, occurring not only in the European continent, as suggested by its common name. Its range embraces part of the northern African Maghreb region, much of southern and western Europe, Anatolia and vast parts of eastern Europe and adjacent Asia. It is a genetically deeply structured species, and the Sicilian pond turtle was recognized as a distinct species (E. trinacris...
Comparative Genomics Identifies Epidermal Proteins Associated with the Evolution of the Turtle Shell
The evolution of reptiles, birds, and mammals was associated with the origin of unique integumentary structures. Studies on lizards, chicken, and humans have suggested that the evolution of major structural proteins of the outermost, cornified layers of the epidermis was driven by the diversification of a gene cluster called Epidermal Differentiation Complex (EDC). Turtles have evolved unique d...
