Population Trend of the World's Monitored Seabirds, 1950-2010. [PDF]
PLoS ONE, 2015 Seabird population changes are good indicators of long-term and large-scale change in marine ecosystems, and important because of their many impacts on marine ecosystems.

Consequences of cross‐season demographic correlations for population viability
Ecology and Evolution, 2023 Demographic correlations are pervasive in wildlife populations and can represent important secondary drivers of population growth. Empirical evidence suggests that correlations are in general positive for long‐lived species, but little is known about the

Influence of allochtonous nutrients delivered by colonial seabirds on soil collembolan communities on Spitsbergen [PDF]
, 2012 Despite a widespread recognition of the role of seabird colonies in the fertilization of nutrient-poor polar terrestrial ecosystems, qualitative and quantitative data documenting any consequential influence on soil invertebrate communities are still ...

FACETS, 2016 We examined the diet of Atlantic puffin (Fratercula arctica) chicks at three midcoast Maine, USA, colonies during the years 2005–2014 and found that the puffins at each island have a distinct diet that has changed in recent years.

Multi-Species Feeding Association Dynamics Driven by a Large Generalist Predator
Frontiers in Marine Science, 2021 Multi-species feeding associations (MSFAs) are temporary communities of animals exploiting the same or co-occurrent resources. Their dynamics are species dependent, often creating competitive interactions, but they can also increase foraging efficiency ...

Energetic consequences of prey type in little penguins (Eudyptula minor)
Royal Society Open Science, 2023 Investigation of foraging decisions can help understand how animals efficiently gather and exploit food. Prey chase and handling times are important aspects of foraging efficiency, influencing the net energy gain derived from a prey item.

Avian Conservation and Ecology, 2021 Powerline collisions have been identified on Kaua'i as a potential contributing factor to the large-scale decline of both Hawaiian Petrel (Pterodroma sandwichensis) and Newell's Shearwater (Puffinus newelli), but the scale of the powerline collision ...

Effects of agricultural practices on foraging habitats of a seabird species in the Baltic Sea
Ecology and Evolution, 2022 Omnivorous and opportunistic species may be good indicators of food availability. Gulls often use human‐impacted landscapes and may respond to changes by altering their feeding ecology.

Scientia Marina, 2003 A country-by-country review of seabird mortality from longline fishing in the Mediterranean Sea and in Macaronesian waters shows a paucity of data. Of 12 Mediterranean countries known to undertake longlining, seabird mortality is only reported for six ...

Large‐scale assessment of intra‐ and inter‐annual breeding success using a remote camera network
Remote Sensing in Ecology and Conservation, 2021 Changes in the physical environment along the Antarctic Peninsula have been among the most rapid anywhere on the planet. In concert with environmental change, the potential for direct human disturbance resulting from tourism, scientific programs, and ...
