The availability of anthropogenic food subsidies has promoted an increase in generalist
opportunistic gull species, which currently breed and forage on predictable anthropogenic …

Gulls are highly opportunistic seabirds, and the exploitation of fishery discards has led to
many population increases worldwide. We investigated the importance of fish in the diet of …

The Mediterranean region is both a hotspot for biodiversity and for the accumulation of
plastic pollution. Many species are exposed to this pollution while feeding, including a wide …

Several bird species benefit from anthropogenic food subsidies, such as landfills and fishing
discards, that are being reduced owing to introduced legislation. For instance, since 2019 …

Anthropogenic food subsidies attract opportunistic generalists like gulls in high densities,
which may lead to negative impacts on human communities and local ecosystems …

For centuries, human activities have altered the population dynamics of wildlife. New
anthropogenic food sources provide a predictable and abundant food supply that often …

The exploitation of forage fish species can modify the functioning of marine ecosystems
potentially impacting the population status of predators. This may be the case for the western …

Global changes, through their impacts on ecosystem trophic structures, are behind regime
shifts and cascading effects, and could result in the reorganization of whole ecosystems. The …

The use of combined conventional and stable isotope analyses to study the diet of seabirds
has become very frequent. Unfortunately species and tissue-specific Trophic Discrimination …

The use of top-consumers as bioindicators of the health of food webs is hampered by
uncertainties in their effective use of resources. In this study, the abundance of stable …
