Rare observations of important events such as birth, predation, innovation, and teaching can be vitally important in directing research toward potentially important areas. Parasite-induced alterations in both appearance and behaviour concur to render infected gammarids more vulnerable to predation, thus promoting parasite transmission. Timing and degree of synchrony in fruit maturation and dispersal were not important sources of variation in predation levels among trees. We also compared predation across three microhabitats of different heights (ground, 1- 1.5 m and > 3 m). These areas may also be refugia from predation by leopard seals, which we found living primarily in near-shore habitats. Pupae at the three sites were placed between two layers of hardware cloth (1 cm mesh) to protect against mice and bird predation. The attraction of both predators to the leaves containing pollen may be the reason for the lower levels of predation on the plants containing pollen. This clearly reduces the strategic motives for cross-subsidization by eliminating traditional predation. Under natural conditions, changes in behaviour regardless of their cause may predispose the paratenic host to predation. A key issue in models of predation is the ability of firms to commit to particular time paths for output or prices. Ideally, natural populations should be monitored to find out if they are negatively affected by increased predation. What are the implications of bird predation on arthropods for cocoa crops? Trade-offs between foraging and predation risks determine habitat use in a desert baboon population. Timing of foraging flights of three species of bats in relation to insect activity and predation risk. These examples are from corpora and from sources on the web.
