Elucidating the ecological factors underpinning migratory strategies of seabirds is necessary for understanding resilience to environmental change. Arctic terns Sterna paradisaea breed in the Northern Hemisphere and are unique for the global scale of their migration.

Breeding biology of Arctic terns (Sterna paradisaea) in the Canadian High Arctic
Polar Biology, 2017The Arctic tern (Sterna paradisaea) is a well-known polar seabird which breeds around the circumpolar Arctic, and which undertakes the longest known annual migration of any organism. Despite its familiarity, there is little information on its breeding biology in the High Arctic, an important baseline against which future studies of climate change ...

Residues of organochlorine chemicals (OC) including polychlorinated biphenyls (PCB) were analyzed by gas chromatography in carcasses of young arctic terns (Sterna paradisaea) and common terns (Sterna hirundo). The birds found dead were collected in 1988 in a breeding colony of the German Wadden Sea.

Dispersal and climate change: a case study of the Arctic ternSterna paradisaea
Global Change Biology, 2006AbstractDispersal is an important evolutionary process that can affect admixture of populations and cause rapid responses to changing climatic conditions due to gene flow from populations at different altitudes or latitudes already experiencing these conditions.

The influence of age on the breeding biology and survival of the Arctic tern Sterna paradisaea
Journal of Zoology, 1976The paper describes the influence of the age of Arctic terns on the breeding biology and postfledging survival. Some of the effects of a “red‐tide” on the terns are described.

Antarctic Science, 1992
An intensive migration of Arctic terns was observed from 7–9 March 1989 in Marguerite Bay (67°50'S 67°30'W). The movement pattern and speed of tern flocks were analysed from time-lapse films of a marine navigation radar. The terns migrated north at altitudes 30–60 m asl along the inner coast of Marguerite Bay. When approaching Pourquois Pas Island, the

Nest defence and predator recognition by Arctic tern (Sterna paradisaea)
2022In the presented work, I describe the behaviour of Arctic terns (Sterna paradisaea) toward predator species that differ in the threat they represent to them and to their nests. I presented textile dummies of great black-backed gull (Larus marinus), peregrine falcon (Falco peregrinus), common raven (Corvus corax) and common eider (Somateria mollissima),

Comparative Biochemistry and Physiology Part A: Physiology, 1987
The indices of red blood were determined in nestlings and adults of Plautus alle and adults of Sterna paradisaea. All measured parameters varied significantly, but the amount of Hb per unit area of erythrocytes did not change over the nestling development of P. alle. In adult P. alle, S.

A change in clutch size in the Arctic Tern Sterna paradisaea in the northern Baltic
1992The modal clutch size in Arctic Terns breeding on the southern coast of Finland was observed to differ from that reported in previous studies. In 1989 and 1990, the frequency of 3-egg clutches was 60% and 45%, respectively in one study colony, and 61 % and 54% in another colony.
