Document Summary
Local enhancement: a strategy in which an individual uses the presence of another as a cue focusing on a particular part of the environment. Individual feeding rates high in rich patches and low in poor. Public information information obtained from the activity or performance of others about the quality of an environmental parameter or resource. Research question: do animals use local enhancement or public information to assess patch quality? (coolen et al. ) Prediction: if only local enhancement information is available, individuals will use it. When local enhancement and public information provide contradictory information, fish rely on public information to select a food patch. Precocial: highly developed and mobile when hatched. When a colonies location becomes unsuitable, they move to a more stable, higher-quality location. Small number of scouts always search for food or better nest locations: recruitment tandem run two individuals move together, where the scout leads the worker to the resource.
