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 […]

Surviving Cyanide – Part One

Eating is dangerous. Are you drinking a glass of wine? Perhaps planning pesto for dinner? The very flavors that attract us to those foods come from toxins plants produce to protect themselves. We humans know to the deadly ones. But imagine you’re a wild herbivore – every bite you take is a risk. Bamboos, and […]

Revealing ancient hybridization’s role in diversification

Hybridization between closely related species is a rapidly emerging field of interest for evolutionary biologists, and the more scientists look for signals of hybridization (with ever fancier tools), the more we learn that hybridization is the norm rather than the exception (Payseur & Rieseberg 2016). While young species pairs tend to hybridize more readily than […]

Reproductive Isolation and the ‘Hockey Assist’ – How a shift to self-compatible mating systems can bring about reproductive isolation

The first steps in the process of speciation are a bit paradoxical when you think about it…how does one freely interbreeding species make the transition to two reproductively isolated, independent species? More specifically, how do intraspecific mating barriers become interspecific? And why even are there intraspecific mating barriers? Well, that last question is easier to […]

The difference 70 miles can make

Adapting to temperature is critical for any organism. Thus, many mammals, especially small, temperature-sensitive ones, have adaptations allowing them to modulate their metabolisms to adapt to their local winter temperatures, at an energetic cost (Chappell, 1980; Garcia-Elfring, Barrett, & Millien, 2019; Geiser & Ruf, 1995). The optimal metabolic modulation could be very precise, and would […]
