Seed Predation by Animals

Seed Predation by Animals Department of Biology University of Chicago, Chicago, Illinois Many plants suffer very heavy pre- and/or post-dispersal seed predation by animals. A few exemplary studies (2,18,38,52,74,87, 106,110,111,124, 140, 161, 162, 171, 181, 187, 196, 197, 203, 205, 207, 217, 220, 227) and a variety of shorter reports scattered through the agricultural, botanical, and zoological literature suggest a large and important, yet unexploited, field of study.

Abstract

Department of Biology University of Chicago, Chicago, Illinois Many plants suffer very heavy pre- and/or post-dispersal seed predation by animals. A few exemplary studies (2,18,38,52,74,87, 106,110,111,124, 140, 161, 162, 171, 181, 187, 196, 197, 203, 205, 207, 217, 220, 227) and a variety of shorter reports scattered through the agricultural, botanical, and zoological literature suggest a large and important, yet unexploited, field of study. It is clear that the pattern of seed predation is highly structured and that it coevolved at, the chemical, spatial, and temporal level. It involves all levels of animal-plant interaction from the internal energy budget of indi­ viduals to the entire community (203 ) .
