Data from: Species-level predation network uncovers high prey specificity in a Neotropical army ant community
- 负责人：
- DOI：
- doi:10.5061/dryad.s6743c5
- 摘要：
- ng about 30% of the known local ant diversity. Using weighted bipartite network analyses, we show that prey specialization in army ants is unexpectedly high
Data from: Trait evolution, resource specialization and vulnerability to plant extinctions among Antillean hummingbirds
- 负责人：
- DOI：
- doi:10.5061/dryad.5770gm7
- 摘要：
- Species traits are thought to predict feeding specialisation and the vulnerability of a species to extinctions of interaction partners

- 摘要：
- following association with novel food types. Shifts in preference can involve at least two phenomena: a change in rank preference or a change in specificity. The former
Data from: Habitat heterogeneity induces rapid changes in the feeding behaviour of generalist arthropod predators
