- 摘要：
- , but local density-dependent dispersal switched from negative (conspecific attraction) to positive (conspecific avoidance), as the colonisation progressed. This study

- 摘要：
- Foraging distributions are thought to be density-dependent, because animals not only select for a high availability and quality of resources, but als

- 摘要：
- Some studies have found that dispersal rates and distances increase with density, indicating that density-dependent dispersal likely affec
Data from: Direct evidence that density-dependent regulation underpins the temporal stability of abundant species in a diverse animal community
