Reproductive effort, cutch size, body size, phylogenetic signal, bet-hedging


Reproductive output is one of the most important characteristics of life-history traits. When a lineage exhibits two different modes of reproduction, the comparison of their reproductive output becomes relevant in order to understand how reproductive output evolution is linked to the breeding form or environmental factors. In this study, we analyzed the reproductive output among genus Sceloporus from the bet-hedging life-history model approach. Published and original data were analyzed under a comparative phylogenetic and standard statistical analyses between environmental variables and life-history traits. No difference in reproductive output between oviparous and viviparous species among the genus Sceloporus was detected. Clutch/brood size was negatively correlated with minimum and average environmental temperature. Furthermore, body size was positively correlated with clutch/brood size with clutch/litter size were correlated with body size. A high level of the phylogenetic signal for body size, body mass, and clutch/brood size was detected, but not for reproductive effort. Since all life-history traits examined seems to have deeply evolutionary history, nevertheless, they still correlated with environmental variables indicating some evidence for bet-hedging. Results was also interpreted under the climate change effects; it seems that these lizards could be facing difficult times managing climate change.
