Chapter 41, Problem 7TYU
FOCUS ON EVOLUTION
Explain why adaptations of particular organisms to interspecific competition may not necessarily represent instances of character displacement. What would a researcher have to demonstrate about two competing species to make a convincing case for character displacement?

Read this quote from Charles Darwin (from Origin of Species). What is he describing?
"Thus, I can understand how a flower and a bee might slowly become, either
simultaneously or one after the other, modified and adapted to each other in the
most perfect manner, by the continued preservation of all the individuals which
presented slight deviations of structure mutually favorable to one another."
An interaction network.
A predator/prey cycle.
O Coevolution.
An obligate mutualism.
WRITE ABOUT A THEME: INTERACTIONS In Batesianmimicry, a palatable species gains protection by mimickingan unpalatable one. Imagine that individuals of a palatable,brightly colored fly species are blown to three remote islands.The first island has no predators of that species; the second haspredators but no similarly colored, unpalatable species; and thethird has both predators and a similarly colored, unpalatablespecies. In a short essay (100–150 words), predict what mighthappen to the coloration of the palatable species on each islandthrough time if coloration is a genetically controlled trait.Explain your predictions
An association of individuals of different species living in the same habitat and having functional interactions is what?

- What is intraspecific competition? What are some examples of how the limited quantity of resources affects intraspecific completion? How does intraspecific competition affect species distribution and their evolution?arrow_forwardSpecies facing competition might evolve mechanism that promotes coexistence rather than exclusion. Justify this statement in light of Gause’s competitive exclusionprinciple, citing suitable examples.arrow_forwardWhich 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_forward
