Resource polymorphism and diversity of Arctic charr Salvelinus alpinus in a series of isolated lakes.

Journal of fish biology - 1 Feb 2013

Woods P J, Young D, Skúlason S, Snorrason S S, Quinn T P

Abstract excerpt

Morphological, dietary and life-history variation in Arctic charr Salvelinus alpinus were characterized from three geographically proximate, but isolated lakes and one large lake into which they drain in south-western Alaska. Polymorphism was predicted to occur in the first three lakes because S. alpinus tend to become polymorphic in deep, isolated lakes with few co-occurring species. Only one morph was evident...
