Patterns in tern trophic diversity in a region experiencing rapid climate change

open access: yesEcosphere
Foraging plasticity provides a mechanism for long‐lived species to adapt to rapidly changing environments. When shifts in food availability occur, individual variation in plasticity can lead to an increase in within‐species trophic diversity.

Emergence, spread, and impact of high-pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica. [PDF]

open access: yesConserv Biol
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

Persistent pollutants in fresh and abandoned eggs of Common Tern (Sterna hirundo) and Arctic Tern (Sterna paradisaea) in Ireland

open access: yesMarine Pollution Bulletin, 2021
Higher levels of persistent pollutants (Σ16PCB, Σ6PBDE, ΣHCH, ΣDDT, ΣCHL) were detected in fresh eggs of Common Terns Sterna hirundo from Rockabill Island near Dublin (Ireland's industrialised capital city) compared to Common and Arctic Terns S. paradisaea from Ireland's west coast.

Variation in Population Synchrony in a Multi-Species Seabird Community: Response to Changes in Predator Abundance. [PDF]

open access: yesPLoS ONE, 2015
Ecologically similar sympatric species, subject to typical environmental conditions, may be expected to exhibit synchronous temporal fluctuations in demographic parameters, while populations of dissimilar species might be expected to show less synchrony.

Adult survival of Arctic terns in the Canadian High Arctic

open access: yesPolar Research, 2018
Arctic tern (Sterna paradisaea) populations are thought to be in decline across much of their range. For long-lived seabirds, determining adult survival rates is key to understanding current population trends and predicting trajectories.

Attendance of scavenging seabirds at trawler discards off Galicia, Spain

open access: yesScientia Marina, 2003
The occurrence of scavenger seabirds at fishing trawlers was studied off Galicia, Spain. A total of 9,368 seabirds of 23 species were recorded during 92 fishing operations in 1998 and 1999.

Reactions of ground-nesting marine birds to human disturbance in the Canadian Arctic

open access: yesArctic Science, 2016
I studied the reactions of five ground-nesting marine bird species (Arctic tern (Sterna paradisaea), Sabine’s gull (Xema sabini), common eider (Somateria mollissima), long-tailed duck (Clangula hyemalis), and Ross’ gull (Rhodostethia rosea)) breeding in ...

Migration routes and non-breeding areas of Common Terns (Sterna hirundo) from the Azores [PDF]

open access: yes, 2015
We describe the migration routes and non-breeding areas of Common Terns (Sterna hirundo) from the Azores Archipelago, based on ringing (banding) recoveries and tracking of three birds using geolocators.

Physiological characteristics of arctic tern Sterna paradisaea chicks in relation to egg volume

open access: yesPolar Research, 1997
The effect of egg volume on body mass, body composition and growth rate in Arctic tern Sterna paradisaea chicks was studied at Ny-Ålesund, on Svalbard (78°55'N, 12°00'E), in order to investigate whether differences in egg size influence the physiological characteristics of the hatchlings.
