These four species present a wide distribution and hence various genetic subpopulations along the European coast. Understanding the forces that create these spatial distributions is a major challenge to ecology, but also has clear economic benefits to humans, by allowing more precise assessments of managed stocks (Giske et al. 1998). While field studies may reveal patterns at a given time and place and laboratory investigations may isolate effects of single causes, models (such as the Dynamic Energy Budget model) may combine several forces in continuous space and time.
The overall aim of this doctoral program is to use the DEB model to better understand the geographical distribution of these species. The relationships between intra- and interspecific differences in DEB model parameters and environmental conditions (temperature, food conditions, salinity) will be described and analyzed. By knowing these relationships, scenarios of impacts of climate shifts on ecosystem productivity and biodiversity can be predicted.
In order to achieve the overall aim, it is intended to integrate the following objectives:
