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.
