Breaking the routine: individual Cory's shearwaters shift winter destinations between hemispheres and across ocean basins
There is growing evidence that migratory species are particularly vulnerable to rapid environmental changes arising from human activity. Species are expected to vary in their capacity to respond toExpand

Effects of artificial illumination on the nocturnal foraging of waders
Large areas of natural and semi-natural habitats are exposed to artificial illumination from adjacent urban areas and roads. Estuarine and coastal wetlands are particularly exposed to suchExpand

Distance to high-tide roosts constrains the use of foraging areas by dunlins: Implications for the management of estuarine wetlands
Abstract Shorebirds are declining all around the world, mostly due to deterioration of the estuarine habitats used in winter and migration. Estuaries cover small areas, so it is essential toExpand

Carry-over effects from breeding modulate the annual cycle of a long-distance migrant: an experimental demonstration.
Carry-over effects relate to events or processes that influence individual performance in a subsequent season, but their occurrence in the annual cycle of migratory avian taxa is seldom studied. WeExpand

THE USE OF OTOLITHS AND VERTEBRAE IN THE IDENTIFICATION AND SIZE-ESTIMATION OF FISH IN PREDATOR-PREY STUDIES
Relationships between the size of otoliths and vertebrae, and body length are presented for eleven teleost species of the north-east Atlantic. Relationships between teleost size and weight are alsoExpand

Do Seabirds Differ from Other Migrants in Their Travel Arrangements? On Route Strategies of Cory’s Shearwater during Its Trans-Equatorial Journey
Long-distance migrants have developed diverse strategies to deal with the challenges imposed by their annual journeys. These are relatively well studied in some avian groups, such as passerines,Expand

Environmental factors drive habitat partitioning in birds feeding in intertidal flats: implications for conservation
We present data on the low-tide distribution of shorebirds in the Tagus estuary, Portugal, and relate the distribution of the bird assemblage with environmental factors. The study was based on anExpand

Variation in numbers and behaviour of waders during the tidal cycle: implications for the use of estuarine sediment flats
Estuarine sediment flats are essential feeding areas for waders, but their exploitation is constrained by the movements of tides. In this cyclic environment the exposure period of sediment flatsExpand

Relationship between mercury levels and diet in Azores seabirds
Mercury concentrations were determined in feather and food samples from adults of 6 seabird species from the Azores archipelago. Mean concentrations ranged from 54 to 432 ng g-' dry weight in foodExpand

An holistic ecological analysis of the diet of Cory's shearwaters using prey morphological characters and DNA barcoding
Knowledge of the dietary choices and trophic niches of organisms is the key to understanding their roles in ecosystems. In seabird diet studies, prey identification is a difficult challenge, oftenExpand
