Genetic Rescue – Fitness and genomic consequences

Posted on 22 Sep, 2020 by Kathleen Grogan

As a PhD student studying the effects of genetic diversity overall and immunogenetic diversity specifically on survival and reproductive success in an endangered primate in captive and wild populations, I thought a lot about the potential effects of inbreeding and … Continue reading →

Hybridization in the depths of the last glacial period created a world-conquering clover

Posted on 30 May, 2019 by Jeremy Yoder

Plants’ flexibility with the structure of their genome — able to cope with proliferating transposons, whole-genome duplications, or even acquisition of complete sets of chromosomes from another species — is a big source of evolutionary novelty. Duplication of a single gene … Continue reading →

Chromosomal inversions and the maintenance of species barriers

Posted on 29 May, 2018 by Alex Twyford

Chromosomal inversions have long fascinated evolutionary biologists for their role in adaptation and speciation. These structural variants are abundant in natural populations and can have diverse evolutionary consequences. They can cause reproductive isolation through hybrid sterility or protect sets of … Continue reading →

The secret life of invaders

Posted on 2 Apr, 2018 by Kathryn Turner

So I have this pet theory. And damn if the evidence doesn’t seem to be piling up. Am I living in the bubble of my own google alerts? Possibly. I’m an evolutionary ecologist and invasion biologist, and (surprise!) my pet … Continue reading →

Genomic signatures of ancient rendezvous and separation in elephant evolution

Posted on 5 Mar, 2018 by Patrícia Chrzanová Pečnerová

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 →

In the aftermath of fire, bluebird species boundaries may blur

Posted on 5 Sep, 2017 by Jeremy Yoder

One of the most clear-cut reasons that species evolve to fill different ecological niches is competition. Two otherwise similar species that use the same resources experience strong selection favoring the use of less-similar resources, if they have the option. The … Continue reading →
