The female perspective of mating in A. femoralis, a territorial frog with paternal care--a spatial and genetic analysis.

The adaptive significance of sequential polyandry is a challenging question in evolutionary and behavioral biology. Costs and benefits of different mating patterns are shaped by the spatial distribution of individuals and by genetic parameters such as the pairwise relatedness between potential matin...
