New story out in PNAS: Evolution of male pregnancy associated with remodeling of canonical vertebrate immunity in seahorses and pipefishes
14. apr. 2020
A recently published paper led by Olivia Roth (GEOMAR; Kiel) together with several members of CEES uncovers a modification of the adaptive immune repertoire of seahorses and pipefish that coincide with evolution of male pregnancy.

Cod-Haddock 2-1 in Barents Sea
10. aug. 2020
In the Boreal-Arctic seas, the two most abundant gadoid fish are the Atlantic cod ( Gadus morhua) and the haddock ( Melanogrammus aeglefinus). Both tend to respond to climate warming by an abundance increase and a change of distribution. Are these changes affecting how they are interacting? Statistical analysis using a state-space threshold model of acoustic and trawl survey data on cod and haddock abundance indicates that the interaction is changing with sea temperature: the cod negatively affecting the haddock when sea temperature is over 4 °C.

Global warming makes polar cod grow larger in the Arctic Barents Sea
24. juni 2020
We studied the effect of changes in sea ice cover, sea temperature, and biomass of prey or predator on the length of polar cod. Our results show a significant negative effect of sea ice cover on length of all age groups of polar cod: Polar cod grow faster when there is less sea ice.
