Beschreibung:

A major question in ecology is: Why are tropical forests so species diverse? A leading hypothesis is the Janzen-Connell model, which assumes that the activities of host specific seed/ seedling predators open up space surrounding parent trees and allow for the establishment of non-conspecifics. This model has been tested over 70 times since 1970 but results have been highly variable. Biologists hold divergent views on whether the model can explain the maintenance of tree species diversity.
