Learn about Central Texas salamanders.
This webinar will discuss a recent survey of genomic variation in Central Texas spring salamanders from the Eurycea neotenes group. The project was designed to ask questions whose answers might inform conservation management of these salamanders. These salamanders have a difficult taxonomic history with controversy surrounding the names of, and boundaries between, nominal species which potentially include the Texas Salamander (E. neotenes), the Fern Bank salamander (E. pterophila), and the Cascade Caverns salamander (E. latitans). We are specifically interested in how genomic variation is organized with respect to geography and with respect to the nominal taxonomy. Our focus is on identifying conservation management units. This required extensive sampling of salamanders from springs and caves and quantification of genetic variation from across the salamanders’ genomes. We measured and mapped contemporary patterns of genomic variation. We also used modeling approaches to understand the history and demography of these salamanders. In this talk, we will discuss combining these analyses to provide a foundation for identifying management units.
