Effects of environmental variability intensity on the integration of phenotypic traits in Wood frogs (L. sylvaticus)Over the past decades, the impact of human activities on the environment has intensified at an unprecedented rate. Climate change, more specifically, has led to the degradation of several habitats, such as wetlands. Due to their semi-permeable skin, amphibians develop in both aquatic and terrestrial environments. The developmental plasticity of their traits must be integrated (correlated) to avoid performance trade-offs between these different habitats. Climatic disturbances increase the unpredictability of hydroperiods and temperatures, which could disrupt the developmental correlation of traits, especially if different traits exhibit varying levels of maximal plasticity. As part of my master’s project, I aim to assess the effects of environmental variability intensity on the degree of phenotypic trait integration and plasticity in the Wood frog (Lithobates sylvaticus). Using an experimental mesocosm design, I will study the degree of correlated responses between various phenotypic and behavioral traits subjected to different drying and temperature conditions. This project will help improve our understanding of the adaptability of amphibians in response to climate change.
