Abstract

Previous studies in fishes and anurans have evidenced that parentage within an egg clutch could influence the degree of paternal care and reproductive strategies because the cost of care for parents. Males of the glassfrog Hyalinobatrachium cappellei care their egg clutches in their territories to protect them from pathogens and desiccation. Here we are going to develop microsatellite DNA markers to assess the relationship between paternal care and the percent of male's genetic contribution to the clutch. Here, it is expected attending males to be the genetic father of the offspring in order to offset costs related to mating opportunity loss and decrease in food intake. The results of our study will provide information hitherto little explored in the literature regarding behavioral strategies to offset the parental investment in Neotropical anurans. (AU)
