Understanding the margin squeeze: Differentiation in fitness‐related traits between central and trailing edge populations of Corallina officinalis
Abstract Assessing population responses to climate‐related environmental change is key to understanding the adaptive potential of the species as a whole. Coralline algae are critical components of marine shallow water ecosystems where they function as important ecosystem engineers. Populations of th...
