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.
Support for the individualistic model of community structure includes (a) the decline of honeybees because of two species of parasitic mites (b) the identification of fig trees as a keystone species in tropical forests (c) the competitive exclusion of one Paramecium species by another (d) the distribution of trees along a moisture gradient in Wisconsin forests (e) theeffects of the removal of a dominant rodent species from an Arizona desert
Environments with low frequency and intensity of disturbance tend to have ________ species diversity because ______.
Group of answer choices
A) low; the best competitors exclude any other species
B) high; disturbances kill off a large number of individuals
C) low; there are fewer late-successional species than early-successional species
D) high; more species can colonize over a longer period of time

- Determine if each statement is correct or incorrect: 1. Ecosystems with fewer numbers of species tend to be less stable. 2. Increasing numbers of species lead to more redundancy which is bad for the ecosystem. 3. More species mean more niche separation. 4. Species with a low resistance will also have low resilience. 5. Disturbances to ecosystems can be both naturally occurring and human caused. 6. Stresses to ecosystems are useful for removing weaker species and ensuring the strongest survive. 7. Bringing non-native species into an area to increase biodiversity makes the ecosystem more stable.arrow_forwardAn ecosystem that is highly capable of recovering and regenerating through secondary succession after a disturbance is exhibiting high resilience.

- 1. 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) resource partitioning, (C) low species richness, (D) pronounced intraspecific competition, (E) coevolution of predator-prey strategies.arrow_forwardAccording 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.arrow_forwardWhen r is a positive number, the population size is (a) stable (b) increasing (c) decreasing (d) either increasing or decreasing, depending on interference competition (e) either increasing or stable, depending on whether the species is semelparousarrow_forward

- Which of the following best predicts the consequences of introducing small Indian mongoose to an island where they did not previously exist?( Invasive species) (Choice A) A The mongoose population will grow rapidly, disrupting the island's community structure by preying on native animals. (Choice B) B The mongoose population size will likely remain smal, and as a result the mongoose population will not be able to outcompete other predator populations for resources. (Choice C) Without any natural diseases, the mongoose population will become established and help increase the species diversity of the island. (Choice D) D Without its typical food sources, the mongoose population will not be able to become established, and the island ecosystem will remain stable. answer explainarrow_forwardCompetition is often an important driver of early succession, while facilitative interactions tend to play a more dominate role later in succession.
