"In order for the tree shrews to reach the exudates, they must climb onto the pitchers and orient themselves in such a way that their backsides are located over the pitcher mouths," explains Dr Clarke.
If the plant is a toilet, it receives nitrogen and other plant nutrients from shrew feces. Species of pitcher plants that do not attract tree shrews have different shapes.
Dr Clarke says it is the "neatest" discovery he has made in more than 20 years of studying Nepenthes meat-eating plants.
"The findings should radically alter how we look at these plants," he says.
Pretty neat indeed, especially if you are a tree shrew. Link -via Zooillogix
