Can small populations benefit from genetic rescue?
The core dogma of conservation biology is clear: small populations are bad for species’ persistence. If we observe a population of endangered vertebrates harboring abundant deleterious mutations but without any reduction in fitness, what is happening there? I would like … Continue reading
Bobbing for Bobcats
Catherine Sirgo wrote this post as a part Dr. Stacy Krueger-Hadfield’s Science Communication course at the University of Alabama at Birmingham. Catherine is a Master’s Candidate within Dr. Thane Wibbels’ lab researching conservation for the Mississippi Diamondback Terrapin in Alabama. Catherine earned … Continue reading

In defense of hatcheries: a response to the "Artifishal" documentary
A month or so ago, I had opportunity to screen the documentary, “Artifishal” (admittedly, a pretty clever title), in a room full of fish biologists, geneticists, and hatchery managers. The premise of the film is that both hatcheries and open … Continue reading
A Highlight of Molecular Ecology outside of Academia
I’ve recently made a career change. Actually, I’m not even sure whether to call it that, or the next step of a natural, if meandering progression of a scientist not on the academic career path. Even though I see more and … Continue reading
Genomic signatures of ancient rendezvous and separation in elephant evolution
Evidence from various levels of the tree of life is showing that we’ve been picturing ancient encounters between related species all wrong and admixture events are probably more common than expected. Even rendezvous among primates, caniforms, and majestic proboscideans often … Continue reading

Experimental harvesting reduces gene expression variation
Human activities represent unique selective pressures for natural populations. This is especially true for fish species where we routinely harvest individuals from the wild, i.e., through fishing. It has been recognized for some time that overfishing can result in population … Continue reading

Mapping genomes and navigating behavior for wildlife conservation
Virginia Aida wrote this post as a final project for Stacy Krueger-Hadfield’s Science Communication course at the University of Alabama at Birmingham. She is currently evaluating a potential pharmacotherapy in traumatic brain injury and anticipates graduating with her MS in summer 2017. Although she … Continue reading

Like Turtles, Terrapin Research Moves a Little Slow
Marlee Hayes wrote this post as a final project for Stacy Krueger-Hadfield’s Science Communication course at the University of Alabama at Birmingham. Her primary interests focus on challenges in conservation and sustainability. Previously, she evaluated fitness of post-hatchling Diamondback terrapins (Malaclemys terrapin), … Continue reading
What's left of the black rhino's genetic diversity?
With the current poaching epidemic we might lose rhinos before we even have time to get to know them. Luckily, the day has come and thanks to Yoshan Moodley, Mike Bruford and their team we know have a pretty good … Continue reading
