Open AccessBoldness predicts foraging behaviour, habitat use and chick growth in a central place marine predator
Animal personality can shape individual’s fitness. Yet, the mechanistic relationship by which individual’s personality traits lead to variations in fitness remains largely underexplored. Here, we used novel ob...

Open AccessGlobal assessment of marine plastic exposure risk for oceanic birds
Plastic pollution is distributed patchily around the world’s oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife ...

Open AccessDrivers of niche partitioning in a community of mid-trophic level epipelagic species in the North Atlantic
According to the principles of community ecology, sympatric species may suffer a selective pressure to decrease their niche overlap through mechanisms of niche partitioning. However, there is still a gap in kn...

Sexual segregation in the foraging distribution, behaviour, and trophic niche of the endemic Boyd’s shearwater (Puffinus lherminieri boydi)
Studies on sex-specific segregation in foraging behaviour and trophic niche have been focussed on large and dimorphic seabirds, with less information on small monomorphic species. Here, we used mini-GPS logger...

Feeding and trophic ecology of Antarctic toothfish Dissostichus mawsoni in the Amundsen and Dumont D’Urville Seas (Antarctica)
Fisheries ecosystem-based management is an important tool for sustainable harvesting of fisheries worldwide. Knowledge of trophic interactions is crucial since changes in trophic balances can induce severe cha...

Foraging costs drive within-colony spatial segregation in shearwaters from two contrasting environments in the North Atlantic Ocean
Foraging spatial segregation is frequent in central-place foragers during the breeding season, but very few studies have investigated foraging spatial segregation between adjacent sub-colonies. Here, we assess...

Seasonal variation in habitat use, daily routines and interactions with humans by urban-dwelling gulls
The effects of growing urbanization have caused an increase in human-wildlife interactions in urban areas. Human-gull conflicts have been particularly studied during the breeding season when gulls cause an obv...

Ingestion of anthropogenic materials by yellow-legged gulls (Larus michahellis) in natural, urban, and landfill sites along Portugal in relation to diet composition
Pollution is a global concern, increasing rapidly throughout marine and terrestrial ecosystems, and affecting many species. Urbanization enhances waste production, leading to the opening of landfills that cons...

Characterization of anthropogenic materials on yellow-legged gull (Larus michahellis) nests breeding in natural and urban sites along the coast of Portugal
Anthropogenic materials are a persistent pressure on ecosystems, affecting many species. Seabirds can collect these materials to construct their nests, which may modify nest characteristics and cause entanglem...

Oceans of stimuli: an individual-based model to assess the role of olfactory cues and local enhancement in seabirds’ foraging behaviour
Oceans are extremely dynamic environments, which poses challenges for top-predators such as seabirds to find food resources. Yet, seabirds evolved sensorial abilities (olfactory senses) along with complex beha...

Facing extremes: Cory’s shearwaters adjust their foraging behaviour differently in response to contrasting phases of North Atlantic Oscillation
Climate projections predict increases in the frequency and severity of extreme climate events over the next decades. Hence, phases of extreme climatic indices are emerging as one of the most dangerous effects ...

Stable isotopes reveal year-round sexual trophic segregation in four yellow-legged gull colonies
Sexual segregation in trophic ecology is widespread among sexually dimorphic marine vertebrates. The degree of such segregation can change throughout the annual cycle, however, year-round data on seabird inter...

Ontogenetic changes in habitat and trophic ecology of the giant Antarctic octopus Megaleledone setebos inferred from stable isotope analyses in beaks
The giant Antarctic Octopus Megaleledone setebos is the largest Southern Ocean octopod whose ecology is poorly known. Here, we study ontogenetic shifts of habitat and trophic ecology of M. setebos throughout its ...

Correction to: Anthropogenic food resources, sardine decline and environmental conditions have triggered a dietary shift of an opportunistic seabird over the last 30 years on the northwest coast of Spain
The article which was recently published contained error in Table 1.

Anthropogenic food resources, sardine decline and environmental conditions have triggered a dietary shift of an opportunistic seabird over the last 30 years on the northwest coast of Spain
Human activities and environmental conditions are the main drivers of ecosystem change. One major alteration near the western Iberian coast has been the collapse of the Atlanto-Iberian sardine Sardina pilchardus ...

Metabarcoding, stables isotopes, and tracking: unraveling the trophic ecology of a winter-breeding storm petrel (Hydrobates castro) with a multimethod approach
Detailed information on diet and foraging ecology is scarce for most small seabirds such as storm petrels. In this study, we used molecular techniques, stable isotope analysis, and geolocators to study the die...

Open AccessUnderstanding how birds rebuild fat stores during migration: insights from an experimental study
Mechanisms underlying fat accumulation for long-distance migration are not fully understood. This is especially relevant in the context of global change, as many migrants are dealing with changes in natural ha...

Natural woodlands hold more diverse, abundant, and unique biota than novel anthropogenic forests: a multi-group assessment
Biodiversity sustained by natural ecosystems, particularly forests, provides ecosystem services essential to human well-being. However, many forests have been severely transformed, notably via monospecific pla...

Foraging strategies of a generalist seabird species, the yellow-legged gull, from GPS tracking and stable isotope analyses
Generalist and opportunistic species, such as the yellow-legged gull Larus michahellis, can feed on a wide variety of food from both marine and terrestrial origins. This work evaluates the potential foraging stra...

Isotopic niches of sympatric Gentoo and Chinstrap Penguins: evidence of competition for Antarctic krill?
As climate change, among other factors, is increasingly affecting Antarctic marine systems, competition for prey may increase between predators, particularly in the Antarctic Peninsula which has warmed more th...
