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

The Hidden History of Kiwi Diversification
Of the millions of Earth’s species that likely remain to be described, a majority is thought to be invertebrates, plants, fungi, or microbes. Nevertheless, the pace of species description in some vertebrate groups has not slackened over the past few … Continue reading
Phenotypes in Comparative Phylogeography
Earlier this week, The Molecular Ecologist contributor Bryan McLean posted about the current state of comparative phylogeography (Riddle 2016). He listed several exciting directions that comparative phylogeography is heading, including more research that includes trait data. As a followup to … Continue reading
A Comparative View of Comparative Phylogeography
A recent issue of PNAS includes papers from a Sackler Colloquium on comparative phylogeography. As stated by the organizers, a major purpose of that gathering “was to bring together leading scientists to address the current state of phylogeography as the … Continue reading
