Open AccessSeabirds show foraging site and route fidelity but demonstrate flexibility in response to local information
Fidelity to a given foraging location or route may be beneficial when environmental conditions are predictable but costly if conditions deteriorate or become unpredictable. Understanding the magnitude of fidel...

Open AccessHPAIV outbreak triggers short-term colony connectivity in a seabird metapopulation
Disease outbreaks can drastically disturb the environment of surviving animals, but the behavioural, ecological, and epidemiological consequences of disease-driven disturbance are poorly understood. Here, we s...

Open AccessA year in the life of a North Atlantic seabird: behavioural and energetic adjustments during the annual cycle
During their annual cycles, animals face a series of energetic challenges as they prioritise different life history events by engaging in temporally and potentially spatially segregated reproductive and non-br...

Open AccessSympatric Atlantic puffins and razorbills show contrasting responses to adverse marine conditions during winter foraging within the North Sea
Natural environments are dynamic systems with conditions varying across years. Higher trophic level consumers may respond to changes in the distribution and quality of available prey by moving to locate new re...

Global Monitoring of Persistent Organic Pollutants (POPs) Using Seabird Preen Gland Oil
Situated at high positions on marine food webs, seabirds accumulate high concentrations of persistent organic pollutants (POPs), such as polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane and it...

Open AccessBringing It All Together: Multi-species Integrated Population Modelling of a Breeding Community
Integrated population models (IPMs) combine data on different aspects of demography with time-series of population abundance. IPMs are becoming increasingly popular in the study of wildlife populations, but th...

Phenological sensitivity to climate across taxa and trophic levels
Differences in phenological responses to climate change among species can desynchronise ecological interactions and thereby threaten ecosystem function. To assess these threats, we must quantify the relative i...

Inter-year differences in survival of Atlantic puffins Fratercula arctica are not associated with winter distribution
Miniature geolocator loggers (Global Location Sensing, GLS) that provide daily locations of birds have revolutionised the study of winter ecology and migration patterns of seabirds. A long-term study of ringin...

Analysis of fatty acids and fatty alcohols reveals seasonal and sex-specific changes in the diets of seabirds
A key challenge in ecology is to find ways to obtain complete and accurate information about the diets of animals. To respond to this challenge in seabirds, traditional methods (usually stomach content analysi...

Egg components vary independently of each other in the facultative siblicidal Black-legged Kittiwake Rissa tridactyla
Egg composition varies both within and between clutches, and mothers are expected to alter their deposition of resources to the egg depending on environmental conditions and breeding strategies. Within-clutch ...

Wintering areas of adult Atlantic puffins Fratercula arctica from a North Sea colony as revealed by geolocation technology
Most seabirds die outside the breeding season, but understanding the key factors involved is hampered by limited knowledge of nonbreeding distributions. We used miniature geolocating loggers to examine the mov...

Integrated data analysis in the presence of emigration and mark loss
Integrated data analyses are becoming increasingly common in studies of wild animal populations where two or more separate sources of data contain information about common parameters. These types of analyses p...

Is bigger necessarily better for environmental research?
In restructuring environmental research organisations, smaller sites generally disappear and larger sites are created. These decisions are based on the economic principle, ‘economies of scale’, whereby the ave...

Incorporating variance uncertainty into a power analysis of monitoring designs
Power calculations usually assume that the components of the population variance are known, but it is frequently the case that they are estimated using data from a pilot study. Imprecision in the estimates is ...

A major increase in snake pipefish (Entelurus aequoreus) in northern European seas since 2003: potential implications for seabird breeding success
Since the early 2000s routine fish surveys have recorded increasing numbers of snake pipefish, Entelurus aequoreus, in the northeast Atlantic. Fishermen and divers have also commented on this increase and pipefis...
