In the middle of Alberta’s boreal forest, a bird eats a wild chokecherry. During his scavenging, the bird is caught and eaten by a fox. The cherry seed, now inside the belly of the bird within the belly of fox, is transported far away from the tree it came from. Eventually, the seed is deposited on the ground. After being broken down in the belly of not one but two animals, the seed is ready to germinate and become a cherry tree itself. The circle of life at work.
Diploendozoochory, or the process of a seed being transported in the gut of multiple animals, occurs with many species of plants in habitats around the world. First described by Charles Darwin in 1859, this type of seed dispersal has only been studied a handful of times. And in a world affected by climate change and increasing rates of human development, understanding this process is becoming increasingly important. [continue]
