Concept explainers
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.

- Complete competitors cannot coexist is a statement of the principle of (a) primary succession (b) limiting resources (c) Mllerian mimicry (d) competitive exclusion (e) character displacementarrow_forwardWhich of the following rows correctly highlight the different types of competition present during the early and late stages of succession? Select one: a. Early Stage Late Stage High interspecific competition High intraspecific competition b. Early Stage Late Stage High intraspecific competition High interspecific competition c. Early Stage Late Stage Low interspecific competition Low intraspecific competition d. Early Stage Late Stage High intraspecific competition Low interspecific competitionarrow_forwardThe 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.arrow_forward
- A predators can feed on several prey species, but prefer to attack those with the weakest defenses. The same predator may shift to a different prey species that becomes more common or more easily overcome when the previousiy preferred prey had acquired better defenses against the predator. This shifting strategy, known as _____________, results in sequential or alternating bouts of pairwise coevolution between many different species. A. resource shifting B. coevolutionary alternation C. ecological character displacement D. cospeciationarrow_forwardWhat process is being described by this figure? 1. mutualism 2. competition 3. predation 4. niche differentiationarrow_forwarda population of mice moves into a field in which secondary succession is occurring.

- Why have frequent small controlled-burn wildfires not helped to maintain chaparral ecosystems? 2 of 302 of 30 Questions Listen Question Why have frequent small controlled-burn wildfires not helped to maintain chaparral ecosystems? Seeds of chaparral shrubs need a large accumulation of leaf litter in order to sprout. The heat from forest fires destroys the roots of chaparral plants. Fire destroys the seeds of many types of chaparral shrubs. Burnt ground encourages the growth of grasses, which compete with shrubs for nutrients.arrow_forwardCapturing and relocating is stressful for animals. In the zebra example, what are the stages of reintroduction, and what purpose does each step serve? Why is the buffalo considered a success story for reintroduction? (And -- based on what you know from lecture, what type of population growth pattern does this indicate?) Park managers use the term “adaptive management”; what do you think this means, and what are two benefits of this approach to managing ecosystems?arrow_forwardWhat is the relationship between a pioneer species and primary succession? A pioneer species is an invasive species that causes areas to experience primary succession. There is not a relationship between a pioneer species and primary succession. The pioneer species only occurs in areas of secondary succession. A pioneer species is important in an area of primary succession because it can grow and thrive in areas where most other species cannot. A pioneer species only inhabits areas of primary succession.arrow_forward
- What is the difference between primary succession and secondary succession? Primary succession occurs when a new species is discovered within an already established species. Secondary succession occurs when a new species invades an area and destroys the species already inhabited there. Primary succession occurs when an area has never supported an ecosystem. Secondary succession occurs when an area has supported an ecosystem but has been cleared of everything except for topsoil. Primary succession occurs when an area has supported an ecosystem but has been cleared of everything except for topsoil. Secondary succession occurs when an area has never supported an ecosystem. Primary succession occurs when an area has supported an ecosystem and an invasive species takes over the area. Secondary succession occurs when an area has never supported an ecosystem and an invasive species takes over the…arrow_forwardCommunity - Competition. 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. This dynamic suggests that extirpation (local extinction) of populations is a far more likely outcome than co-existence. How, in your opinion, does this affect management policies aimed at increasing biodiversity and proliferation of inter and intra population and interspecies variation. Reason your point of view. 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_forwardIn some marine habitats in New England, the population density of lobsters has been depleted due to heavy fishing. When this happens, it often follows that the diversity of species in the biological communities is reduced. Based on this observation, how would you characterize lobsters? a keystone organism a decomposer a crustacean a superior predator a producer The composition of a community refers to the nutrients available in the soil. type of succession that occurs locally. sunlight available to drive the energy needed for metabolism. extent vegetation covers the ground--a desert has low composition. types of species adapted to living there. Small fish sometimes swim very close to large predatory fishes such as sharks. There is no risk since the shark does not feed on these smaller fish. The small fish are able to eat the remains of prey such as seals that the shark rips apart when eating.…arrow_forward
