Species facing competition might evolve mechanism that promotes coexistence rather than exclusion. Justify this statement in light of Gause’s competitive exclusionprinciple, citing suitable examples.
The most intense interactions often occur between individuals of the same species. What concept discussed in this chapter can be used to explain this phenomenon?
EVOLUTION CONNECTION Contrast the selective pressuresoperating in high-density populations (those near the carryingcapacity, K) versus low-density populations.

- EVOLUTION LINK Biologists have wondered how introduced species that would probably have limited genetic variation (due to the founder effect) survive and adapt so successfully that they become invasive. Part of the answer may be that invasive species are the result of multiple introductions instead of a single one. Explain how multiple introductions from a species native area to an introduced area could increase that species invasion success.arrow_forwardTerritoriality behaviors actually decrease competition between members of the same species. Explain why this is the case, and therefore how territoriality is favored by natural selection.arrow_forwardTerritoriality behaviors actually decrease cometition between members of the same species.

- When Charles Darwin discovered the various fish species on the Galapagos islands he was surprised to find so many different but related species in such a small geographic area which of the following best illustrates the correlation between competitive advantage in an individual streets in a particular environmentarrow_forwardWhich statement about zero population growth isoclines of two competing species is true? A. Species coexistence requires that the two isoclines cross. B. The crossing of the two isoclines is a sufficient condition for species coexistence. C. If the species coexist, they will each do so at a higher density than either would if placed alone. D. Strongly competing species can only coexist if the two species have very different carrying capacities. E. Coexistence will occur if the two isoclines are parallel.arrow_forwardDefine predation. How does the predator-prey relationship differ from the parasite-host relationship? Why is the evolutionary race be-tween predator and prey one that the predator cannot afford to win?arrow_forward
- Which of the following can explain why species are able to coexist, even if the competitive exclusion principle is generally true? a) Species may be competitively equivalent, with the outcome of each competitive encounter being essentially random. b) Competitive exclusion may take many generations; prior to that point, there will be coexistence. c) Spatial heterogeneity in the distribution and concentrations of limiting resources can result in variation in the strength of competition across the landscape. choose all the answers that apply.arrow_forwardWhat process is being described by this figure? 1. mutualism 2. competition 3. predation 4. niche differentiationarrow_forwardThe principle of competitve exclusion states thata) Competition between two species always causes extinction or emigration of one species.b) Two species will stop reproducing until one species leaves the habitat.c) Two species cannot coexist in the same habitat. d) Two species that have exactly the same niche cannot coexist in a community.arrow_forward

Thank you! I'll leave a thumb up You are quantifying competition between two species of flour beetles. For species 1, K1 = 160 and α = 1. For species 2, K2 = 360 and b = 4. Suppose the initial population sizes are 180 of species 1 and 80 of species 2. Predict the short-term dynamics of each population and the final outcome of interspecific competition.arrow_forwardIntraspecific competition reduces allelic diversity by Select one: a. relieving predator pressure on the prey population b. allowing K-selected species to have a selective advantage over r-selected species c. creating a competitive advantage to certain alleles d. allowing two different species occupying the same niche to compete for resourcesarrow_forward
