Ripp-Off Rodents Are Key in Life Cycle of Tropical Trees
DAILY DISRUPTION JULY 16, 2012There’s no honor among thieves when it comes to rodent robbers—which turns out to be a good thing for tropical trees that depend on animals to spread their seeds.
Results of a yearlong study in Panama, published online in Proceedings of the National Academy of Sciences the week of July 16, suggest that thieving rodents helped the black palm tree survive by taking over the seed-spreading role of the mighty mastodon and other extinct elephant-like creatures that are thought to have eaten these large seeds.
