Sažetak
Phenotypic diversity is multifactorial and understanding how it arises within and among species is a long-term goal of evolutionary biology. This study tested the association between environment, phenotype and genotype of Mytilus galloprovincialis populations along the eastern Adriatic coast. The analyses of environmental variables, mussel morphology, genetic architecture, biomarkers, and induced mortality were implemented on native populations and in transplant experiments. Core results underline that phenotypic variability exists between mussel’s populations and is driven by numerous environmental factors. Results of the transplant experiment led to a conclusion that biomarker status varies among Adriatic regions dependent upon the environmental variables, and between clean and polluted sites depending on metal concentrations. Mesocosm experiment showed population effect on survival and biomarker response. Estimates of mussel’s genetic architecture pointed to conclusion that analysed morphological traits are polygenic and moderately heritable. This study promotes the importance of combining quantitative genetics with experimental approaches to obtain insightful data on phenotypic plasticity and adaptive responses.
