#Evol2017 catch-up — Effects of range expansions on mating system

Two weeks (more about that in a post I’ve written for Wednesday!) after the closing day of the 2017 Evolution Meetings, the Molecular Ecologists have all dispersed from Portland, though some may have left things behind! Still, the conference was so … Continue reading

On hyRAD-X, another option for museum genomics

Last year, I profiled Suchan et al.’s “hyRAD” method for reduced-representation genome sequencing of degraded sources of DNA using RAD probes. While it’s too early to say whether hyRAD will be widely used by molecular ecologists looking to integrate historic … Continue reading

Different ways to have sex, yet still be a weed

Baker (1955) noticed that when mates are lacking, the ability to undergo self-fertilization will greatly enhance colonization success. Uniparental reproduction seems to be common in colonizing species, whether it’s from a continent to an oceanic island, during a biological invasion or during range … Continue reading

Deep in the meadow, under the … seagrass, a bed of temporally stable diversity?

Genetically diverse populations are often more stable and productive. For habitat-forming organisms, such as seagrasses, this results in increased habitat complexity and more abundant associated communities (e.g., Hughes and Stachowicz 2004, Reusch et al. 2005).  Spatial patterns of genetic diversity … 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

That’s an H. erato of a different color!

What drives different coloration among birds, insects, flowers? One of the major goals in evolutionary studies is understanding what is going on in DNA that makes organisms different. A fancy way to say this is studying how an organism’s genotype … Continue reading

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
