According to the Janzen-Connell hypothesis, in order for pathogens or herbivores to contribute to the maintenance of diversity: Select all that apply. the pathogens/herbivores must be host-specific. mortality of seedlings due to competition between plants must be less important than mortality due to herbivores/pathogens. the infections must be avirulent. the pathogens/herbivores must result in lower seedling mortality close to adult plants of the same species.

Answer:

The correct answer is -

The pathogens/herbivores must be host-specific.

Mortality of seedlings due to competition between plants must be less important than mortality due to herbivores/pathogens.

Explanation:

According to the Janzen-Connell hypothesis, it is showed by research that seeds of rare species are more likely to escape seed from herbivores/pathogens. According to this theory, pathogens should be able to infect only a specific species.

Competition is less important in terms of mortality of seeds than it is due to the predators such as herbivores/pathogens of a species according to this hypothesis.
