Connecting fish, rivers, and people

Stalking the Elusive Shoal Bass

Guest Author: Amy Cottrell Editor: Solomon David The sun began creeping up over the tree tops and casting morning shadows and specks of daylight on the water surface, slowly lighting up more and more of the heavily vegetated creek bank. We paddled the quiet corridor, antenna rotating side to side in front of me as…

Red Tide

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. We’ve included Twitter and popular science articles alongside analyses of natural selection, genetic drift, and traditional scientific…
