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)

- What is the evidence that coevolution of different resource uses allows different finch species to coexist in the Galapagos Islands? Researchers have conducted experiments adding and removing food, and have studied how bill sizes have changed. Researchers have removed one finch species on islands where there are multiple seed-eating species, and have studied how bill sizes of the remaining species have changed. Researchers have compared bill sizes of finch species on islands where they are alone and islands where there is a second seed-eating finch. There is no scientific evidence at all. This is pure storytelling.arrow_forwardIf the human species were to suffer a population crash, what are three species that might move in to occupy part of our ecological niche?arrow_forwardAccording to the competitive exclusion principle, two species cannot exist together if they occupy the same niche. Either they diverge their niches so they can coexist or one species will die out.All of the following are consistent with the principle of competitive exclusion EXCEPT Select one: a. Birds and bats both consume flying insects, but birds are active in the day and bats are active at night. b. Two species that share the same niche will exclude other competing species. c. Different bird species forage for insects in different parts of the same tree. d. When two species of Paramecium are grown in the same medium, one strain will eventually eliminate its competitor.arrow_forward
- Question 1 Question 1 options: ___________ competition occurs when one species reduces the resource available to the other. __________ competition occurs when one species reduces access to the resource. Question 2 Which of the following is not characteristic of interspecific competition? Question 2 options: A) Two or more species interact. B) The population size of at least one species decreases. C) The limiting resource does not change over time. D) One or more resources is limiting. Question 3 Which of the following does not directly affect the intensity of competition? Question 3 options: A) Niche overlap. B) Niche breadth. C) The density of competitors. D) The presence of similar species.arrow_forwardCompetition 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_forwardExplain the Predator-Prey Population Dynamics ?arrow_forward
