Recently I blogged about the one thing I teach that nobody ever forgets: the meaning, and etymology, of the life-history term semelparity.

But of course they don’t, and every year I find grading the exams a bit depressing because (and here’s a shocker) some students get some questions wrong. But there’s one thing I teach that nobody ever forgets – and it came up in my Population Biology course just last Friday. Continue reading
