Energy and life history theory to predict ecological responses of marine organisms in the Mediterranean Sea in a context of global change
Energy is the key-factor to understand the ecological success of a species in a context of global change. Indeed, successful populations persist over time if individuals can manage sufficient energy to maintain structures, growth and reproduce throughout their whole life cycle. The prime effect of g...
