Nature versus nurture: estimating heritability of deer antlers and body size

Aaron Shafer is an Assistant Professor at Trent University, Canada. Their research uses genomic and bioinformatics tools to characterize adaptive and demographic processes in natural populations. Research organisms in the lab currently include shrews, deer, caribou and mountain goats. Lead-author Aidan Jamieson was an honours biology student who is now doing a MSc at York […]

An ode to the mudosphere

Field work has been cancelled the world over due to COVID-19. Over at The Molecular Ecologist, the contributors curated some photos from our exploits in the field as a nostalgic post to life pre-lockdown (if you have photos, be sure to send them to TMEfieldworkphotos@gmail.com). My lab spends a lot of time in mud – […]

What if by overestimating the complexity of the genomic basis of a trait, we’re underestimating the complexity of its evolutionary dynamics?

The genomic bases, or architectures, of complex traits are… complex. But what if by overestimating the complexity of some aspects of the genomic architecture of a trait, we’re actually underestimating the complexity of its evolutionary dynamics? This notion struck me when two things clicked while I was preparing a fellowship application back in 2017. First, […]

A horse of a different color patterning mutation

Connecting genotypes to the complex phenotypes they produce is a fundamental goal of genetics. Variation in coat color pigmentation, partly due to the relative ease at which different patterns can be identified, is one of the best-characterized traits at the genetic level, with examples from sheep (Zhang et al., 2017), cattle (Li et al., 2016), […]

Is European bison really back?

Humans constantly interact with their environment. They modify habitats, transfer species from one place to another, domesticate some species while contributing to the extinction of others. To reverse the process of extinction, we’ve been reintroducing taxa since the 1800s. Reintroduction refers to the action of establishing self-sustaining and healthy populations of extinct or critically endangered […]
