ARBEITSVORHABEN Multi-Locus Evolution from Genes to Communities Our understanding of evolutionary change is largely built on the traditional genetic framework wherein the genes of individuals are responsible for differences in the traits they express. However, there is a growing appreciation of the fact that the traits of individuals are often influenced by the genes possessed by others. While there have been several models that have considered how these types of "indirect" genetic influences impact evolutionary processes, there are still important gaps in our understanding. To help close these gaps, we will work towards a general framework for understanding how various phenomena contribute to the relationship between genetic and phenotypic variation and how this, in turn, influences evolutionary processes. We aim to incorporate as wide an array of influences as possible, including "epigenetic" processes, interactions between genes at different scales, social interactions and interspecific interactions. To achieve this goal, we will develop a flexible analytical (mathematical) framework that unifies the influences of different phenomena by identifying fundamental modes through which they impact the relationship between genotype and phenotype. To maximize the link to the topic of the focus group, we will emphasize the evolution of positive interactions (cooperative or mutualistic) and negative interactions (conflict and competition). Our overarching goal will be to identify general processes and concepts that unify the contributions of different types of effects to evolutionary change.
