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 is the main toxin found in these frogs 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 call,which ultimately lead to a fall in the entire population into one species.

Explain why it was necessary to use boiling alcohol? What is the purpose of the iodine? Part Two What was the purpose of keeping the leaf in the dark and then covering it with a cardboard cut-out? What conclusions can you draw from this part of the lab? Part Three 7. In this experiment what was the purpose of adding the soda lime? 8. Why was a sealed bag placed around each plant? 9.
