Students in my BIOL 201 class watching Plants are Cool, Too. On screen is shot of Mike Moore and myself walking at White Sands National Monument.
Mike Moore pointing at the sticky yellow ring at the base of an Anulocaulis flower stem.
Blackboard with 5 possible pre-zygotic barriers to gene flow, 3 possible post-zygotic barriers, and a choice between allopatric or sympatric speciation. Students choose their preferred options through discussion after watching the video.
How I use our #gypsum adaptation episode of #PlantsAreCoolToo (starring @gypsumbotany.bsky.social) in class: What barriers to gene flow are likely at play re: 2 ringstem species we show + what type of #speciation can be hypothesized?
