Adaptive Genetic Differentiation Between Spatially Proximate Annual and Perennial Life History Types of a Marine Foundation Species.

Abstract excerpt

Diversity in life expectancy is common in flowering plants. In the seagrass Zostera marina , a vital foundation species in estuarine ecosystems, annual and perennial varieties occur in close proximity, raising the question of whether these lifespan strategies represent locally adapted genetic variation or plastic phenotypes influenced by the environment. Our study combined field transplant experiments and...
