      Global climate change is causing abiotic shifts such as higher air and ocean temperatures, and disappearing sea ice in Arctic ecosystems. These changes influence Arctic-breeding seabird foraging ecology by altering prey ...

    • Thick‑billed Murres in breeding pairs migrate and overwinter far apart but in similar photic environments 

      Huffeldt, Nicholas P.; Ballesteros, Manuel; Helm, Barbara; Linnebjerg, Jannie F.; Merkel, Flemming R.; Mosbech, Anders; Frederiksen, Morten (Peer reviewed; Journal article, 2024)
      Scheduling between mates in species with long-term pair bonds can be essential for positive fitness. The annual cycle in photoperiod is the primary environmental cue used by many animals to synchronize behavior and physiology ...
