The Mediterranea module aims at simulating the dynamics of intraspecific biodiversity in brown trout population, focusing on the interactions between two lineages of interest for population managers: Mediterranean and Atlantic lineages. To do so, this module provides a framework linking genes to behaviour and survival.
The module is based on the previous Bidasoa module, and therefore offers the same potential: dendritic and heterogeneous landscape, fragmentation, migration, complex life cycle, genetics and demography.
However, while genes are considered as neutral in the Bidasoa module, here they code for the MED or ATL character. Fish can thus be pure breed (MED or ATL) or hybrids somewhere in between with various levels of introgression.
Reproductive isolation is handled at two main levels:
The goal of this module is to explore the range of conditions and interplay between possible pre- and post-zygotic isolation that may influence the dynamics of intraspecific biodiversity. Because some of these reproductive isolation relationships can be inspired from real data (Jordi Gil ongoing PhD, Arnaud Caudron's data), it should also help to assess the interest for including evolutionary biology in population management models.
