Objective of the Symposium
Intra-specific diversity is the most fundamental element of biodiversity. It is the product of the interaction between genotypes and the environment, and is expressed as a given diversity in phenotypes. Natural selection acts upon the individual phenotypes within a population, so intra-specific diversity should define the evolutionary path of a species and its resilience to environmental change. Exploring and understanding the causes and consequences of intra-specific diversity in marine fishes is essential to the development of strategies for the sustainable management of these resources.
Marine fish species can have large effective population sizes and wide larval dispersal. This can maintain gene flow between populations and so act against the processes of local adaptation that would generate and maintain intra-specific diversity. Nonetheless, there is growing genetic evidence for fine-scale intra-specific diversity caused by natural selection in marine fish species, although the functional significance of such diversity remains to be described. There have been relatively few common-garden experiments to explore processes and outcomes of local adaptation in marine fish species. Indeed, despite many years of mechanistic studies, physiologists and behaviourists still have an incomplete understanding of the enormous complexity of fish phenotypes and, in particular, how the environment and genotype interact to generate diversity in these.
This satellite symposium will promote knowledge exchange amongst the fields of population genetics, evolutionary biology, ecology, eco-physiology and behaviour, towards improved understanding of the links between genotypes, environments and phenotypes in marine fish species.
