According to the Janzen-Connell Hypothesis, for Pathogens or Herbivores to Contribute

According to the Janzen-Connell hypothesis, for pathogens or herbivores to contribute to the maintenance of diversity requires that:

A) the infections be avirulent.
B) the pathogens/herbivores be host-specific.
C) the pathogens/herbivores result in lower seedling mortality close to adult plants of the same species.
D) mortality of seedlings due to competition between plants be less important than mortality due to herbivores/pathogens.
