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?arrow_forwardWhich of the following best explains the connection between increased competition and the evolution of a species by natural selection? Individuals migrate to another area in order to avoid competition for limited resources in the current ecosystem. Individuals that have traits that allow them to outcompete others survive better and produce more offspring. Individuals must become stronger to compete for resources, and this increased strength is passed on to the next generation. Individuals that must compete for limited resources are more likely to have diseases that cause mutations.arrow_forwardCan you please help find the answer that is reasonable base on this chart?arrow_forward
- 1. Describe two types of interactions between two competing species. 2. Explain how potentially competing species may co-exist. 3. Explain resource partitioning. Give an example. 4. Discuss the co-evolution of predator defences. 5. What is mutualism? Discuss in the context of coevolution. 6. Explain optimal foraging 7. Explain the Red Queen view of evolution 8. Explain one problem related to the concept of coevolution. Give an example. 9. What are the 4 examples of social behaviour among species according to Herron and freeman (2015). Discuss one example of each type of interaction.arrow_forwardSpecies interactions can be categorized into five different groups. List, define them, and provide an example of each.arrow_forwardWhat 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_forward
- You are studying two new species that have a mutualistic relationship. How would you determine if the mutualism is facultative or obligate? What types of observational data would you collect and what type of experiment would you conduct?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_forwardThe most intense interactions often occur between individuals of the same species. What concept discussed in this chapter can be used to explain this phenomenon?arrow_forward
- Which of the following statements is consistent with the principle of competitive exclusion? Bird species generally do not compete for nesting sites Two species with the same fundamental niche will likely exclude all other species Natural selection tends to increase competition between closely related species When two species are in direct competition for the same resource, one species will eventually prevailarrow_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_forwardDescribe two interspecific interactions where both species benefit and both species are at a disadvantage.
