Development of the Lipid Accumulation Window hypothesis to explain Calanus finmarchicus dormancy

Slide 2

Data Sources and Collaborators

Proxies for dormancy entry and exit

AG: Anticosti Gyre, NW Gulf of St. Lawrence

Possible dormancy cues

Climatological temperature at 5 m

Mean chlorophyll-a, 0 – 50 m

Analysis of variance

Conclusions

Slide 12

Lipid accumulation window hypothesis:
Step 1:Decision to enter dormancy in stage CV is made in stage CIV.  Criterion is attainment of 30% lipid content by wt.
