They were hunted to near extinction before international protections were enacted in 1935. As the species recovered, researchers have acquired a myriad of […]
What can we learn about marine mammals from a liter of water?
With a new set of tools focused on environmental DNA, or eDNA, we can learn a lot! eDNA approaches are built on the premise that organisms leave a trace of DNA in the water they inhabit, for example, through sloughed cells, urine, and feces. We can, therefore, extract organismal DNA from a water sample without […]
