Home Departments and Research Groups Research Group Hau Projects Projects of the research group "Evolutionary Physiology" Evolution of hormone-trait connections (Project leader Michaela Hau) We are exploring the linkage between the hormones testosterone and corticosterone with behavior and physiology in various bird species. [more] Bioenergetic-endocrine perspective of telomere dynamics (Project leader Stefania Casagrande) We investigate the physiological routes by which glucocorticoids determine telomere dynamics during growth and the resulting fitness consequences. [more] Adaptive changes of mitochondrial bioenergetics and glucocorticoids in different environmental gradients (Project leader Stefania Casagrande) Individuals vary significantly in how they respond to energetic challenges. [more] Glucocorticoid reaction norms across diverse life history stages using a comparative approach (Project leader Stefania Casagrande) How are glucocorticoids regulated before and during reproduction in vertebrates with a different pace of life?
