Life history responses depend on timing of cannibalism in a damselfly

1. Cannibalism has often been suggested as an important mechanism to reach the necessary developmental stage and size before a critical time horizon is reached, but this role has been largely unexplored. We studied effects of cannibalism on the life history of the damselfly Lestes viridis under combinations of a time constraint (by manipulating the perceived time available in the growth season) and a biotic constraint (density).status: publishe
