      Global warming is a nonlinear process, and temperature may increase in a stepwise manner. Periods of abrupt warming can trigger persistent changes in the state of ecosystems, also called regime shifts. The responses of ...

    • Diverging phenological responses of Arctic seabirds to an earlier spring 

      Descamps, Sébastien; Ramírez, Francisco; Benjaminsen, Sigurd; Anker-Nilssen, Tycho; Barrett, Robert; Burr, Zofia; Christensen-Dalsgaard, Signe; Erikstad, Kjell-Einar; Irons, David B.; Lorentsen, Svein-Håkon; Mallory, Mark L.; Robertson, Gregory J.; Reiertsen, Tone Kristin; Strøm, Hallvard; Varpe, Øystein; Lavergne, Sébastien (Peer reviewed; Journal article, 2019)
      The timing of annual events such as reproduction is a critical component of how free‐living organisms respond to ongoing climate change. This may be especially true in the Arctic, which is disproportionally impacted by ...
