    • Happy hatchday! How does timing of hatching affect the survival of larval Gadus morhua in a changing environment? 

      Sorø, Fridtjov Falch (The University of Bergen, 2019-06-22)
      The classical match-mismatch hypothesis proposes that the timing between larval first feeding and food availability is an important driver of year-class strength. With climate change and the warming of the oceans, it is ...
