16. Community Robustness Analysis : Theoretical Approaches to Identifying Keystone Structures in Ecological Communities
Sammanfattning : Most of the world’s ecosystems suffer from stress caused by human activities such as habitat destruction, fragmentation, overexploitation of species and climate change. These factors affect the reproduction and/or survival of individual species as well as interactions between species in ecological communities. LÄS MER

19. Stress susceptibility, beta-blocker use and cancer survival
Sammanfattning : Accumulating evidence suggests that chronic stress may influence tumour biology through activation of neuroendocrine pathways and thus impair survival. However, measuring stressful exposures and their influence on health is challenging, partly due to substantial inter-individual variation in stress susceptibility. LÄS MER
