Blog Biodiversity: Related Species in the Scicomm Ecosystem

It’s my first semester teaching Evolution & Ecology at Nicholls State University; with plenty of challenging and complex topics to tackle, I’ve also been given the latitude to integrate more science communication (scicomm) into this upper-level biology course.
