Chapter 54, Problem 11TYU
An ecologist studying several forest-dwelling, insect-eating bird species does not find any evidence of interspecific competition. The most likely explanation is (a) lack of a keystone species (b) low species richness (c) pronounced intraspecific competition (d) coevolution of predator–prey strategies (e)

- Competition between species on the same trophic tier leads to four potential outcomes, 3 are deterministic (zero sum games where one species goes extinct and the other maximizes their growth to balance at the carrying capacity) and one where both competitors survive, but neither does well. A) This dynamic suggests that extirpation (local extinction) of populations is a far more likely outcome than co-existence. How does this affect management policies aimed at increasing biodiversity and proliferation of inter and intra population and interspecies variation. B) Endangered species are defined by low growth rates (r) and low K (reflecting high demand for resources). What are the implications of both these factors on the outcome of competition scenarios, especially the most common scenario of alternate stable states?arrow_forwardWhich of the following biological interactions can be considered interspecific mutualism?
