Hypotheses and tracking results about the longest migration: The case of the arctic tern [PDF]

open access: yesEcology and Evolution, 2019
The arctic tern Sterna paradisaea completes the longest known annual return migration on Earth, traveling between breeding sites in the northern arctic and temperate regions and survival/molt areas in the Antarctic pack‐ice zone.

Paralytic shellfish toxins associated with Arctic Tern mortalities in Alaska [PDF]

open access: yesHarmful Algae, 2022
Harmful algal blooms produce biotoxins that can injure or kill fish, wildlife, and humans. These blooms occur naturally but have intensified in many locations globally due to recent climatic changes, including ocean warming. Such changes are especially pronounced in northern regions, where the effects of paralytic shellfish toxins (PSTs) on marine ...

GNSS Transpolar Earth Reflectometry exploriNg System (G-TERN): Mission Concept [PDF]

open access: yesIEEE Access, 2018
The global navigation satellite system (GNSS) Transpolar Earth Reflectometry exploriNg system (G-TERN) was proposed in response to ESA’s Earth Explorer 9 revised call by a team of 33 multi-disciplinary scientists.

Inuit knowledge of Arctic Terns (Sterna paradisaea) and perspectives on declining abundance in southeastern Hudson Bay, Canada. [PDF]

open access: yesPLoS ONE, 2020
The Arctic Tern (Sterna paradisaea; takatakiaq in Inuttitut) breeds in the circumpolar Arctic and undertakes the longest known annual migration. In recent decades, Arctic Tern populations have been declining in some parts of their range, and this has ...

Arctic tern flyways and the changing Atlantic Ocean wind patterns

open access: yesClimate Change Ecology, 2023
Migratory bird trajectories are the result of their own speed and direction in combination with wind speed and direction. Several studies have focused on the interplay between bird migration and general wind patterns, however, the majority of them did ...

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.

Arctic tern-optimized weighted feature regression system for predicting bridge scour depth

open access: yesEngineering Applications of Computational Fluid Mechanics
This paper presents a pioneering artificial intelligence (AI) solution – the Arctic Tern-Optimized Weighted Feature Least Squares Support Vector Regression (ATO-WFLSSVR) system to aid civil engineers in accurately predicting scour depth at bridges.

Foraging Behaviours of Breeding Arctic Terns Sterna paradisaea and the Impact of Local Weather and Fisheries

open access: yesFrontiers in Marine Science, 2022
During the breeding season, seabirds are central place foragers and in order to successfully rear chicks they must adjust their foraging behaviours to compensate for extrinsic factors.

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.
