Table 1 Mortality and cannibalism rates of Baikal endemic amphipod species E. verrucosus, E. cyaneus, and the ubiquitous Holarctic species G. lacustris during sampling, pre-acclimation, and long-term acclimation to temperatures different from the respective preference temperature.

From: Low annual temperature likely prevents the Holarctic amphipod Gammarus lacustris from invading Lake Baikal
