Testes size seen through the glass of amphibian care
TRENDS IN ECOLOGY & EVOLUTION(2024)
Abstract
Despite the great diversity of parental care types found in amphibians, studies linking them to postcopulatory sexually selected traits are scarce, presumably due to a lack of data. Valencia-Aguilar et al . used fieldwork and museum collections to show that paternal care appears to trade -off with testes size in glass frogs.
