Question
Chapter 40, Problem 8TYU
Summary Introduction
To discuss:
How evolutionary history and ecological factors affect the distribution of species.
Concept introduction:
Earth was not always the way we see it today. Over billions of years, the differing environmental conditions (like early Earth atmosphere, ice age and more), evolution, continental drift, extinction and many more, have shaped the face of Earth. Thus, to survive and reproduce, different species have moved around to find suitable niches on land as well as water and adapted to the new ecological factors.

Discuss how the distribution of a species can be affected both by its evolutionary history and by ecological factors. Could ongoing evolutionary change also affect its distribution? Explain.

Question: Summarize how new species can arise by explaining the differences between allopatric and sympatric isolation. Give a real example of when allopatric speciation has been observed and when sympatric speciation has been observed.
WRITE ABOUT A THEME: INTERACTIONS One factorfavoring rapid population growth by an introduced speciesis the absence of the predators, parasites, and pathogens thatcontrolled its population in the region where it evolved. In ashort essay (100–150 words), explain how evolution by naturalselection in a region of introduction would influence the rateat which native predators, parasites, and pathogens attack anintroduced species.

Asap. Thanks Imagine a population of cacti living on an imaginary island called Plantopia. These cacti evolved to stop producing spines because there are no herbivores on Plantopia. Every year, a few cactus seeds are washed onto the shores of Plantopia from the mainland. There are many large herbivores on the mainland. (Tip: Try drawing the scenario to help you visualize it.) Name three mechanisms of evolutionary change ( 3 of mutation, natural selection, genetic drift, andgene flow.) that may be acting on alleles for spine production on Plantopia. For each mechanism, explain what effect it may have on spine production, and whether this change is adaptive or non-adaptive.arrow_forward

Denoted as H, this index is calculated as: H = -Σpi * ln(pi) where: Σ: A Greek symbol that means “sum” ln: Natural log pi: The proportion of the entire community made up of species i The higher the value of H, the higher the diversity of species in a particular community. The lower the value of H, the lower the diversity. A value of H = 0 indicates a community that only has one species. The Shannon Equitability Index is a way to measure the evenness of species in a community. The term “evenness” simply refers to how similar the abundances of different species are in the community. Denoted as EH, this index is calculated as: EH = H / ln(S) where: H: The Shannon Diversity Index S: The total number of unique species What is the Shannon diversity index value for this community?
