Effects of urbanization on the foraging ecology and microbiota of the generalist seabird Larus argentatus
Larus gull species have proven adaptable to urbanization and due to their generalist
feeding behaviors, they provide useful opportunities to study how urban environments …

Accumulation of chemical elements and occurrence of microplastics in small pelagic fish from a neritic environment
The assessment of contaminant exposure in marine organisms often focuses on the most
toxic chemical elements from upper trophic level species. Information on mid-trophic level …

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 …

Using a visual deterrent to reduce seabird interactions with gillnets
Bycatch is one of the main threats to seabird conservation. In Portugal, there are alarming
estimates of seabirds bycaught per year in bottom gillnet fisheries, which get entangled …

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 …

How fishing intensity affects the spatial and trophic ecology of two gull species breeding in sympatry
Fisheries produce large quantities of discards, an important resource for scavenging
seabirds. However, a policy reform banning discards, which is soon to be implemented …
