• A continent-wide search for Antarctic petrel breeding sites with satellite remote sensing 

      Schwaller, Matthew R.; Lynch, Heather J.; Tarroux, Arnaud; Prehn, Brandon (Peer reviewed, 2018)
      The Antarctic petrel (Thalassoica antarctica) has been identified as a key species for monitoring the status and health of the Southern Ocean and Antarctic ecosystems. Breeding colonies of the Antarctic petrel are often ...
    • A continent-wide search for Antarctic petrel breeding sites with satellite remote sensing 

      Schwaller, Matthew R.; Lynch, Heather J; Tarroux, Arnaud; Prehn, Brandon (Journal article; Peer reviewed, 2018)
      The Antarctic petrel (Thalassoica antarctica) has been identified as a key species for monitoring the status and health of the Southern Ocean and Antarctic ecosystems. Breeding colonies of the Antarctic petrel are often ...
    • Antarctic petrels ‘on the ice rocks’: wintering strategy of an Antarctic seabird 

      Delord, Karine; Kato, A.; Tarroux, Arnaud; Orgeret, F.; Cotté, C.; Ropert-Coudert, Yan; Cherel, Y.; Descamps, Sebastien (Peer reviewed; Journal article, 2020)
      There is a paucity of information on the foraging ecology, especially individual use of sea-ice features and icebergs, over the non-breeding season in many seabird species. Using geolocators and stable isotopes, we defined ...
    • Effects of human-induced disturbances and weather on herbivore movement 

      Leclerc, Martin; Tarroux, Arnaud; Fauchald, Per; Stien, Audun; Tveraa, Torkild; St-Laurent, Martin-Hugues (Journal article, 2019)
      Human-caused habitat disturbances and climate change are leading threats to biodiversity. Studying the impacts of human activities on wildlife from a behavioral perspective is a relevant starting point to understand the ...
    • Foraging tactics in dynamic sea-ice habitats affect individual state in a long-ranging seabird 

      Tarroux, Arnaud; Cherel, Yves; Fauchald, Per; Kato, Akiko; Love, Oliver P.; Ropert-Coudert, Yan; Spreen, Gunnar; Varpe, Øystein; Weimerskirch, Henri; Yoccoz, Nigel; Zahn, Sandrine; Descamps, Sebastien (Peer reviewed; Journal article, 2020)
      1. Individual heterogeneity in diet and foraging behaviour is common in wild animal populations, and can be a strong determinant of how populations respond to environmental changes. Within populations, variation in ...
    • Relationships between isotopic ratios, body condition and breeding success in a High Arctic seabird community 

      Hovinen, Johanna Emilia Heidi; Tarroux, Arnaud; Ramirez, Francisco; Forero, Manuela; Descamps, Sébastien (Peer reviewed, 2019)
      Predators such as seabirds are often used as bio-indicators of the marine environment. This is based on the assumption that changes in seabird populations are driven by changes in their prey. We tested this assumption in ...
    • Spring phenology shapes the spatial foraging behavior of Antarctic petrels 

      Fauchald, Per; Tarroux, Arnaud; Tveraa, Torkild; Cherel, Yves; Ropert-Coudert, Yan; Kato, Akiko; Love, Oliver P.; Varpe, Øystein; Descamps, Sébastien (Journal article; Peer reviewed, 2017)
      In polar seas, the seasonal melting of ice triggers the development of an open-water ecosystem characterized by short-lived algal blooms, the grazing and development of zooplankton, and the influx of avian and mammalian ...
    • Temporal variation in trophic relationships among three congeneric penguin species breeding in sympatry 

      Tarroux, Arnaud; Lydersen, Christian; Trathan, Philip N.; Kovacs, Kit M. (Journal article; Peer reviewed, 2018)
      Penguins are a monophyletic group in which many species are found breeding sympatrically, raising questions regarding how these species coexist successfully. Here, the isotopic niche of three sympatric pygoscelid penguin ...
