Linking life history with physiology to assess the vulnerability of amphibians to global change
Considering that amphibian population declines are at the forefront of the biodiversity crisis, understanding the mechanisms that might allow animals cope with environmental change are of key importance for improving our ability to predict population dynamics and for developing suitable conservation strategies. Phenotypic plasticity has the potential to buffer organisms from changing environmental conditions by reducing the sensitivity of life-sustaining processes and increasing physiological tolerances. However, the capacity for phenotypic plasticity might differ between amphibian life stages. In her talk, Katharina will provide some insights into her research that encompass a broad range of aspects related to amphibian ecophysiology. Combining field, experimental, and meta-analytical approaches, she investigates how environmental stressors associated with global change affect vital rates such as growth, development, and metabolism, and examines the life-stage specific capacity to cope with novel environments and challenges by exhibiting phenotypic plasticity as well as the underlying mechanisms of across-life stage effects.
