The biggest problem in landscape genetics and how to fix it
Landscape genetics is a field that has expanded rapidly in recent years, but that doesn’t mean that it hasn’t gone without criticism. Perhaps the largest problem with landscape genetics (LG) studies is one of timing. If you observe genetic differentiation … Continue reading

Long distance dispersal of modern humans outside of Africa
Long distance dispersal (LDD) has long known to be an artifact of human migrations out of Africa. However, the effects of LDD on modern human diversity, and models of LDD in human colonization are yet to be characterized. Using an … Continue reading
Anti-predatory adaptations in sticklebacks and butterflies
Two recent studies analyze character shifts in response to different selection regimes – (1) Mullerian mimicry wing patterns in Heliconius butterflies, and (2) anti-intraguild-predator adaptations in armor and shape of threespine sticklebacks. Hoyal Cuthill and Charleston 2015 Wing patterning genes … Continue reading
Landscape genetics shows that Tanzanian forest monkeys feel the heat of human influence
A new publication appearing in Heredity applies new methods for associating population genetic data with landscape resistance to an tropical, endangered species. The authors utilize multiple measurements of landscape resistance, like forest cover and distance from the nearest village, to select the … Continue reading
Environmental association analyses: a practical guide for a practical guide
Obtaining extensive SNP data for your organism of choice isn’t such a feat these days, but actually matching that breadth of data with appropriate analyses is still a challenge. Fortunately, there has been an avalanche of new methods to make … Continue reading

Should we use Mantel tests in molecular ecology?
No. Stop. At least that is the message from a new publication in Methods in Ecology and Evolution by Pierre Legendre and colleagues (pay-walled, but I found a pdf here). Mantel tests should simply not be used to test hypotheses … Continue reading

A couple years ago, Benoit Simon-Bouhet ended up sharing an office with Eric Pante, then a post-doc fellow in his former lab. The two quickly realized they were in a lab in which few people had the expertise or taste for coding. Thus, on … Continue reading
