Merging the "Morphology-Performance-Fitness" Paradigm and Life-History Theory in the Eagle Lake Garter Snake Research Project.

摘要: SYNOPSIS The morphology-performance-fitness paradigm for testing selection on morphological traits has seen decades of successful application. At the same time, life-history approaches using matrix methods and perturbation studies have also allowed direct estimate acting vital rates that comprise them. Both methodologies been successfully applied to garter snakes long-term Eagle Lake research project reveal morphology, such as color pattern, number vertebrae, gape size; birth size, growth rates, juvenile survival. Here we conduct a reciprocal transplant study in common laboratory environment morphology life-history. To place our results ecomorphology paradigm, measure performance outcomes (feeding growth, insulin-like factor 1 titers) variation (body condition) their fitness consequences survival-a trait large sensitivities these snake populations, therefore is thought be subject strong selection. better merge two complementary theories, end by discussing findings nexus morphology-performance-fitness-life history highlight what approaches, when combined, can about wild.
