- If a species of fruit-eating bat eats the same species of fruit in the same patch of forest as a species of fruit-eating bird, but the individuals of the two vertebrate species never touch, taste, feel, hear, or smell each other because the bird feeds during the daytime and the bat feeds at night, which of the following would be the most likely type of species interaction between the two species? O a. Neutralism O b. Exploitation competition O c. Interference competition С. O d. Ammensalismarrow_forward1. 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_forwardThe population size of a species capable of being supported by the environment is called its ________. a. limit b. carrying capacity c. biotic potential d. logistic growth patternarrow_forward
- There are 190 grey tree frogs in a swamp. The population is under carrying capacity. If r = -0.093 frogs/year, predict the population size the next year. (round to a whole number) a) 208 b) 93 c) 18 d) 190 e) 172arrow_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_forwardWhich 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_forward

- Capturing 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_forwardIn winter, the snowshoe hare diet primarily consists of buds from bog birches.
