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, […]

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 […]
Studying the genetics of migration using hybrids from a migratory divide
Every spring, nature enthusiasts are excited for another bird migration made evident by the countless posts on social media noting rare warblers spotted in backyards and high species counts on birding trips. And the excitement is warranted, as migration is an amazing feat, both ubiquitous and complex, requiring coordination of numerous adaptations for the birds […]
What happens when hunting history, whale culture, genetics, and an international collaboration work towards a common goal?
Right whales were given their name because they were the rightwhales to hunt: they swim slowly near the ocean’s surface and make predictable annual migrations to easily accessible bays along the coast. They were hunted to near extinction before international protections were enacted in 1935. As the species recovered, researchers have acquired a myriad of […]
Surviving cyanide – one path or many?
Cyanide is deadly – to most things. In high enough doses it blocks the body’s ability to create energy by interrupting cellular respiration. But even at non-lethal doses it has knock-on effects throughout the body. Despite this, a few mammals eat it regularly. In my last post, I described how I found multiple ways in […]
Mountains high … valleys wide … can keep me from getting to you
The Sierra Nevada range towers over the Basin below, cutting the skyline with a jagged edge as far as the eye can see. Mountain ranges, like the Sierra Nevada, are symbolic of western North America and present barriers not only to most day hikers, but to many plants and animal too. For many alpine taxa, […]
