Data from: Combined bottom-up and top-down pressures drive catastrophic population declines of Arctic skuas in Scotland
- 负责人：
- Perkins, Allan
- DOI：
- doi:10.5061/dryad.v056r5h
- 摘要：
- predation reducing productivity. Arctic skua Stercorarius parasiticus, a kleptoparasite of other seabirds, is one such species. 2. The aim of the study
Data from: Demographic responses of a site-faithful and territorial predator to its fluctuating prey: long-tailed skuas and arctic lemmings
- 负责人：
- DOI：
- doi:10.5061/dryad.8041k
- 摘要：
- g-tailed skua sustain well changes in lemming dynamics, including temporary collapses (e.g. 10 years). A high floater-to-breeder ratio emerges from rigid
Data from: Multiple stressors in a top predator seabird: potential ecological consequences of environmental contaminants, population health and breeding conditions
- 负责人：
- DOI：
- doi:10.5061/dryad.7ts26
- 摘要：
- –74°N) of great skua (Stercorarius skua) in the north-eastern Atlantic (Shetland, Iceland and Bj?rn?ya [Bear Island]). POPs (organochlorines [OCs
Data from: Modelling flight heights of lesser black-backed gulls and great skuas from GPS: a Bayesian approach
- 负责人：
- DOI：
- doi:10.5061/dryad.dp2ms
- 摘要：
- in altitude measured by GPS for lesser black-backed gulls and great skuas, tracked throughout the breeding season. We also examine how location and light levels
Data from: Sex-specific arrival times on the breeding grounds: hybridizing migratory skuas provide empirical support for the role of sex ratios
- 负责人：
- DOI：
- doi:10.5061/dryad.6v5g3
- 摘要：
- south polar skua (Catharacta maccormicki). These populations differed in their operational sex ratio caused by the unidirectional hybridization of male
