A pheromone function for sexual dimorf glands in amphibians

Pheromone communication is a widespread phenomenon in the animal kingdom, but there is still little known about the use of pheromones in frogs. Although there is more and more evidence that frogs use pheromones, studies of these chemical signals are sparse compared to the plethora of data on visual and acoustic signals. However, there are reasons to believe that sex pheromones in frogs are a general communication tool. Many species have glands with a pronounced gender-specific activity during the breeding period. The purpose of this study is to study the function of two sexually dimorphic glands in frogs, and in particular to test the hypothesis that they produce pheromones.
