Postnatal growth rates covary weakly with embryonic development rates and do not explain adult mortality probability among songbirds on four continents
Thomas E. Martin, Juan C. Oteyza, Adam E. Mitchell, Ahva L. Potticary, P. Lloyd
2016, American Naturalist (185) 380-369
Growth and development rates may result from genetic programming of intrinsic processes that yield correlated rates between life stages. These intrinsic rates are thought to affect adult mortality probability and longevity. However, if proximate extrinsic factors (e.g., temperature, food) influence development rates differently between stages and yield low covariance between...
