The Janzen–Connell hypothesis is a widely accepted explanation for the maintenance of tree species biodiversity in tropical rainforests.
 It was published independently in the early 1970s by Daniel Janzen and Joseph Connell.
 According to their hypothesis, host-specific herbivores, pathogens, or other natural enemies (often referred to as predators) make the areas near a parent tree (the seed producing tree) inhospitable for the survival of seedlings.
 These natural enemies are referred to as 'distance-responsive predators' if they kill seeds or seedlings near the parent tree, or 'density-dependent predators' if they kill seeds or seedlings where they are most abundant (which is typically near the parent tree).
 Such predators can prevent any one species from dominating the landscape, because if that species is too common, there will be few safe places for its seedlings to survive.
 However, because the predators are host-specific (also called specialists), they will not harm other tree species.
 As a result, if a species becomes very rare, then more predator-free areas will become available, giving that species' seedlings a competitive advantage.
 This negative feedback allows the tree species to coexist, and can be classified as a stabilizing mechanism.
