Artificial connectivity … have we overlooked the native range?

Invasive species are problematic throughout the world’s ecosystems, down even to their very name which incites heated debates. Every month, studies are published that describe the genetic structure and gene flow of non-native species in their introduced ranges. Often, these … 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

A tale of mammoths and a disappearing lake

A wonderful study revealed a sad story of the St. Paul Island population of woolly mammoths. Using a creative and diverse set of analytical approaches, scientists identified freshwater shortage as the likely cause of their extinction. A cross-disciplinary collaboration of … 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

The not so singular process of hybridization

What, if anything, are hybrids? Zach Gompert and Alex Buerkle ask this question in a special issue in Evolutionary Applications. Hybrids occur when unrelated individuals mate, but how distant do the taxa need to be to constitute a cross? The varied … Continue reading

Steelhead in a random forest: identifying the genetic basis of migration

Genome-wide association studies (GWAS) have been quite successful in identifying variants associated with various phenotypes (I suppose there is some debate surrounding this statement. For an interesting, if dated, discussion look here). While most of this work was originally conducted … Continue reading

Disentangling the wolf-coyote admixture through an ancestry-based approach

Large carnivores like bears and wolves still pose a puzzle for systematics and population genetics. The more data we get, the more complex their evolutionary history seems to be.
