Chapter 24, Problem 10TYU
Summary Introduction
To explain: How the differences of sexual selection in strawberry poison dart frogs (Dendrobates pumilio) could arise and affect the evolution of reproductive isolation in allopatric versus sympatric populations.
Concept introduction:
Strawberry poison-dart frogs (Dendrobates pumilio) are found in Central America mainly in the Costa Rica and adjacent mainland of Panama. Pumiliotoxin which is the main toxin in these frogs is due to their dietary intake of formicine ants. These frogs exhibit an amazing array of color variation which is considered to be the basis of intraspecific male mating calls which lead to ultimately fall the entire population into one species.

What are biofertilizers and mention the significance
PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen.
How would increased estrogen affect the river otter population?

- magine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different.
