Textbook Question
Chapter 58.3, Problem 2CC
Inhibition implies that competition exists between species, with early-arriving species tending to outcompete later arrivals, at least for a while. Does competition or mutualism feature more prominently in facilitation?
Figure 58.8 Three models of succession. A, B, C, and D represent four stages, with D representing the climax community. An arrow means “is replaced by,” + stands for “facilitation,” − stands for “inhibition,” and 0 indicates no effect. The facilitation model is the classic model of succession. In the inhibition model, early-arriving species outcompete later-arriving species. The tolerance model depends on which species gets there first. The colored arrows show that succession may bypass some stages in the tolerance model.

Students have asked these similar questions
According to the resource-ratio hypothesis (a.k.a. R-star), what factor(s) will determine the
maximum number of competing species that could possibly coexist in a community? (Note:
either one or more-than-one answer could be correct)
.what does the number of limiting resources in a community tell us?
The number of limiting resources in the community
The net primary productivity of the community (NPP).
The number of trophic levels that are present in the community.
| The intrinsic rate of increase (r) of each species in the community.
The colonization rate of each species that can access the habitat.
The graph above is from a paper by Dave Tilman published in 1994. Which of the following statements is consistent with the graph?
A) The results contradicts the intermediate disturbance hypothesis
B) Increasing diversity increases community stability
C) The results support the intermediate disturbance hypothesis.
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?
