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 […]

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 […]

Jumping genes help resolve obscure species relationships

Figuring out evolutionary relationships between species is hard enough when they diversified recently, but what if they rapidly diversified many millions of years ago? A group of baleen whales, the rorquals (Balaenopteridae), for example, diversified starting about 10.5 million years ago (Figure 1; Árnason et al. 2018). Within this group, the evolutionary relationship of the […]
