Comportamento reprodutivo e seleção sexual em Dendropsophus bipunctatus (Spix, 1824) (Anura, Hylidae)

Abstract: Studies on sexual selection in anuran amphibiansvariação no sucesso reprodutivo decorrente da variação no número de parceiros sexuais obtidos (Wade, 1979). Segundo Summers (1992), uma forma mais completa de definir seleção sexual seria: um processo pelo qual indivíduos mais bem sucedidos em selecionar, atrair e competir por parceiros, alcançam maior sucesso reprodutivo do que aqueles que são menos bem sucedidos.Seleção sexual pode também ser considerada como uma força seletiva fundamental na evolução INTRODUÇÃ… Show more

“…The mating system of anurans includes competition between males (Arak, 1983) or choice of females (Ryan, 1985), in which females are considered a limiting resource to the reproductive success of males (Robertson, 1986;Wogel & Pombal Jr., 2007). Duellman & Trueb (1994) stated that many anuran males could remain fasted during the reproductive period, which may explain the low number of specimens with stomach contents in our study.…”

“…Larger females produce larger eggs, or spawns, when compared with smaller females, and have a higher probability of producing more than one offspring per breeding season (MONNET & CHERRY 2002, SILVA & ROSA-FERES 2010. In species where males are larger than females, size is associated with territoriality, combat, and mating success (MONNET & CHERRY 2002, WOGEL & POMBAL 2007, SILVA & ROSA-FERES 2010.…”
