    • Experimentally determined temperature thresholds for Arctic plankton community metabolism 

      Holding, Johnna; Duarte, Carlos M.; Arrieta, Jesús M.; Vaquer-Suyner3, Riser; Coello-Camba, Alexandra; Wassmann, Paul; Agusti, Susana (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Climate warming is especially severe in the Arctic, where the average temperature is increasing 0.4 C per decade, two to three times higher than the global average rate. Furthermore, the Arctic has lost more than half of its summer ice extent since 1980 and predictions suggest that the Arctic will be ice free in the summer as early as 2050, which could increase the rate of warming. Predictions ...

    • Thermal thresholds of phytoplankton growth in polar waters and their consequences for a warming polar ocean 

      Coello-Camba, Alexandra; Agusti, Susana (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-02)
      Polar areas are experiencing the steepest warming rates on Earth, a trend expected to continue in the future. In these habitats, phytoplankton communities constitute the basis of the food web and their thermal tolerance may dictate how warming affects these delicate environments. Here, we compiled available data on thermal responses of phytoplankton growth in polar waters. We assembled 53 ...

    • Warming and CO2 enhance arctic heterotrophic microbial activity 

      Vaqué, Dolors; Lara, Elena; Arrieta, Jesús M.; Holding, Johnna; Sa, Elisabet L; Hendriks, Iris E.; Coello-Camba, Alexandra; Alvarez, Marta; Agusti, Susana; Wassmann, Paul; Duarte, Carlos M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-20)
      Ocean acidification and warming are two main consequences of climate change that can directly affect biological and ecosystem processes in marine habitats. The Arctic Ocean is the region of the world experiencing climate change at the steepest rate compared with other latitudes. Since marine planktonic microorganisms play a key role in the biogeochemical cycles in the ocean it is crucial to ...
