Characteristics of Calanus finmarchicus dormancy patterns in the northwest Atlantic

Slide 2

Data sources

Proxies for dormancy entry and exit

AG: Anticosti Gyre, NW Gulf of St. Lawrence

Possible dormancy cues

Onset of dormancy ANOVA

Climatological temperature at 5 m

Mean chlorophyll-a, 0 – 50 m

Emergence from dormancy ANOVA

Dormancy duration is not related to deep water temperature during dormancy







Dormancy duration is inversely related to surface temperature at onset

Conclusions

Calanus IBM overview

Lipid accumulation window hypothesis:
Decision to enter dormancy in stage CV is made in stage CIV.  Criterion is attainment of 30% lipid content by weight
