Data from: Predator-prey role reversal may impair the recovery of declining pike populations

Jonas Nilsson, Henrik Flink & Petter Tibblin
Many fish populations have experienced declines in recent decades due to anthropogenic disturbances, such as overfishing and habitat exploitation. Despite management actions many populations show a limited capacity to recover. This may be attributed to reversal of predatory‐prey roles, yet empirical evidence to that effect remains scarce. Here we combine field and laboratory studies to investigate the interaction between pike (Esox lucius), a large keystone top predatory fish, and the small‐bodied mesopredatory threespine stickleback (Gasterosteus...

Opposite latitudinal patterns for bird and arthropod predation revealed in the experiments with differently colored artificial prey

The strength of biotic interactions is generally thought to increase towards the equator, but support for this hypothesis is contradictory. We explored whether predator attacks on artificial prey of eight different colours vary among climates and whether this variation affects the detection of latitudinal patterns in predation. The data set provides number of damage marks on each of 1320 plasticine caterpillars of eight different colours, which were attached to branches of woody plants and exposed...
