I was lucky to be in the car at the right time this morning to catch a story about Mastodons in Manhattan: A Botanical Puzzle, i.e., why honey locust trees in NYCity have long thorns – an interesting story (click on the link and click on “Listen Now”) which, among others, features our blog-friend Carl Buell.

Neat! This reminds me of the Science paper from a two months ago or so about how megaherbivores can change the landscape in Africa. What I would like to know, then, is if the tree produces more thorns/defenses when its being actively browsed versus trees that are not (the acacia trees in the Science study produced more thorns when they were being “attacked” by the herbivores; it’s a plastic response). Thanks for sharing this, Bora!
