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.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
