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 t...
