Migration and life history alternatives in a high latitude species, the broad whitefish, Coregonus nasus Pallas
Abstract – We examined the expected changes in the life history trajectory of an Arctic species, broad whitefish, in the lower Mackenzie River between an anadromous population with spawning migrations of 350–450 km and a potamodromous population with spawning migrations of 5–12 km. Based on life his...
