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

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

The almighty CRISPR-Cas9 technology: The future of conservation?

In the first post on CRISPR-Cas9, I’ve explained how bacteria and archaea create a “database” of infections and use it as a form of prokaryotic immunization. This time, I’m going to concentrate on how biotechnology turns this natural phenomenon into … Continue reading

Personal narrative of a journey from zoos to academia

Back in February, the South Carolina Aquarium and The Center for Humans and Nature hosted the finale in the Holland Lifelong Learning series of “Why do zoos and aquariums matter?” in Charleston. I’ll admit, at first, the main reason I … Continue reading

Using R to mine species data

Many of us generate more data than we know what to do with (speaking of which: keep an eye out for the 2016 NGS Field Guide, coming soon!), so it’s easy to forget about the piles of data already at our fingertips. Research potential is … Continue reading

Lonesome George, no longer?

Galapagos tortoises summon up images of great, lumbering beasts on idyllic islands that planted the seeds of natural selection in the young naturalist, Charles Darwin. In a recent paper, Poulakakis et al. (2015) provide genetic evidence of two lineages of tortoises … Continue reading

Gorillas (genomes) in the mist

Mountain gorillas are an endangered great ape subspecies that number around 800 individuals, inhabiting mountain ranges in central Africa. They have been the subject of numerous field studies, but few genetic analyses have been carried out. Xue et al. (2015) sequenced … Continue reading
