Extremophile Fishes: Ecology, Evolution, Conservation
Tobler Lab at the University of Missouri—St. Louis
In May, we visited Bitter Lake National Wildlife Refuge as part of our ongoing work supported by a Recovery Challenge Grant focused on Gambusia nobilis (the Pecos gambusia). Our team conducted surveys of spring-associated aquatic habitats to monitor population status…
We’re excited to celebrate an exceptional spring semester for Casey Ernest, one of our standout graduate researchers! In April, Casey earned 2nd place in the Math/Computer Science/Natural Sciences Division at the UMSL Graduate Research Fair for her poster, “Are There...
We recently had the opportunity to visit Hazelwood Central High School, where students presented their plans for building a greenhouse—and they were fantastic. Their proposals were thoughtful, creative, and full of ownership and initiative. It was inspiring to see how...
In March, members of our lab traveled to the Huasteca Potosina region of Mexico for a collaborative field trip focused on Astyanax mexicanus, the Mexican tetra. We joined researchers from Suzanne McGaugh’s lab (University of Minnesota), Paty Ornelas’ lab (UNAM),...
Kyliyah Walker, an undergraduate researcher in our lab, was recently featured in UMSL Daily for presenting her work at the UM System’s Undergraduate Research Day at the Missouri State Capitol. Her project explores how diet affects hydrogen sulfide tolerance in...
We are proud to share that our lab member, Soren Johnson, a third-year biology PhD student, was recently featured in UMSL Daily for his innovative research on cave-dwelling fish. The article highlights Soren’s fieldwork in Tabasco, Mexico, where he studies...
We’re pleased to share our lab’s contribution to a new paper in Molecular Ecology that explores how cold-water releases from dams can affect the development of the endangered razorback sucker (Xyrauchen texanus). This species evolved in the warm, dynamic waters...
We’re excited to announce the publication of our latest paper in Current Biology. This study explores how repeated evolutionary transitions to toxic hydrogen sulfide-rich environments shape gene expression and genetic divergence in populations of Poecilia mexicana. By analyzing multiple independent...
