The role of industrial fisheries and oceanographic change in the decline of North Sea black‐legged kittiwakes
Summary 1 Marine predators can be adversely affected by human activities in several potentially interacting ways. Industrial fisheries can affect predator populations adversely throughExpand

Scale‐dependent climate signals drive breeding phenology of three seabird species
Breeding at the right time is essential for animals in seasonal climates in order to ensure that the energy demands of reproduction, particularly the nutritional requirements of growing young,Expand

Low energy values of fish as a probable cause of a major seabird breeding failure in the North Sea
Many seabirds in the North Sea feed on lesser sandeels Ammodytes marinus during the breed- ing season. Unprecedented breeding failures were recorded at many seabird colonies on the east coast ofExpand

The demographic impact of extreme events: stochastic weather drives survival and population dynamics in a long-lived seabird.
1. Most scenarios for future climate change predict increased variability and thus increased frequency of extreme weather events. To predict impacts of climate change on wild populations, we need toExpand

Modelling responses of herring gull and lesser black-backed gull populations to reduction of reproductive output: implications for control measures.
1. Between 1984 and 1988 breeding output of herring gulls Larus argentatus and lesser black-backed gulls L. fuscus on the Isle of May, Scotland was severely restricted by the repeated destruction ofExpand

Reproductive Senescence in a Long‐Lived Seabird: Rates of Decline in Late‐Life Performance Are Associated with Varying Costs of Early Reproduction
Evolutionary theories of senescence predict that rates of decline in performance parameters should be shaped by early‐life trade‐offs between reproduction and somatic maintenance. Here we investigateExpand
