Occurrence of Novel and Legacy Per/Polyfluoroalkyl Substances (PFASs) in Scopoli’s Shearwater (Calonectris diomedea) Feathers

Diversity
Per- and polyfluoroalkyl substances (PFASs) are contaminants of great concern due to their ubiquitous environmental occurrence in the environment and their potential adverse effects on organisms.

A comparison of two seabird communities on opposite coasts of the Alborán Sea (western Mediterranean)

Scientia Marina, 2003
We compared the seabird communities at two sites of the southern and northern shores of the Alborán Sea in the Western Mediterranean (Melilla and Adra respectively) during a whole year. Similarities and differences in environmental characteristics of the

UVS is rare in seabirds

Vision Research, 2011
Ultraviolet-sensitive vision (UVS), believed to have evolved from an ancestral state of violet-sensitive vision (VS), is widespread among terrestrial birds, where it is thought to play a role in orientation, foraging, and sexual selection. Less is known, however, about the distribution and significance of UVS in seabirds.

Estimating the total mortality of seabirds following a marine heat wave

Conservation Biology, EarlyView.
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

Diversity of Culturable Yeasts in the Feces of Mew Gulls Breeding in Natural and Urban Habitats, with Insights into the Antifungal Susceptibility of the Observed Pathogens

Birds
Migratory birds play an important role in the spread of yeasts in the environment over long distances and in different geographical regions. Human activities, in turn, have a major impact on the biology of wild birds and, consequently, on the microbial ...

Variable sea‐ice conditions influence trophic dynamics in an Arctic community of marine top predators

Ecology and Evolution, 2019
Sea‐ice coverage is a key abiotic driver of annual environmental conditions in Arctic marine ecosystems and could be a major factor affecting seabird trophic dynamics.

Airborne Remote Sensing of a Biological Hot Spot in the Southeastern Bering Sea

Remote Sensing, 2011
Intense, ephemeral foraging events within localized hot spots represent important trophic transfers to top predators in marine ecosystems, though the spatial extent and temporal overlap of predators and prey are difficult to observe using traditional ...

Assessing responses of reef island seabirds to environmental and anthropogenic drivers

Conservation Biology, EarlyView.
Abstract Tropical insular ecosystems face escalating, cumulative impacts of land‐ and sea‐based ecological threats that jeopardize the long‐term sustainability of their native communities. This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey ...

Tourists and the Seabirds in Galapagos [PDF]

Oryx, 1979
Are the seabird colonies in the Galapagos Islands harmed by the ever increasing numbers of tourists? So far the National Park authorities have been able to safeguard the main nesting grounds from trampling by keeping visitors to prescribed paths, but the birds could be harmed in other ways and these need to be investigated.

Insights from three decades of IUCN Red List assessments catalyzing shark, ray, and chimaera conservation

Conservation Biology, EarlyView.
Abstract The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is a critical measure of global aquatic and terrestrial biodiversity status. It is also the basis for the Red List Index, which tracks extinction risk over time.
