Life cycle of the copepod Calanus hyperboreus in the Greenland Sea
A suite of physiological strategies and adaptations performed by the developmental stages support survival of this species in harsh environments.
A high frequency time series at Weathership M, Norwegian Sea, during the 1997 spring bloom: the reproductive biology of Calanus finmarchicus
Results show that the reproductive period of C. finmarchicus in the Norwegian Sea is to some extent decoupled from the phytoplankton bloom, due to high female abundance the total population egg production prior to the bloom was the same as during the bloom.
Diapause in the marine copepod, Calanus finmarchicus — A review
An attempt was made to classify patterns of overwintering physiology according to insect diapause phases of Calanus Jinmarchicus, and a short comparison was also made with the diAPause of freshwater cyclopoids.
Overwintering of Calanus finmarchicus and Calanus helgolandicus
It is concluded that overwintering copepodids do not feed and Mortality during moulting and time span between capture and onset of moults decreased during autumn and winter, suggesting internal development during overwwintering.
Reproductive cycles of dominant calanoid copepods in the North Sea
It is concluded that for Helgoland waters temperature controlled egg production by its effect on prosome length, and that food conditions were not limiting.
A high frequency time series at weathership M, Norwegian Sea, during the 1997 spring bloom: feeding of adult female Calanus finmarchicus
Body carbon and carbon/nitrogen ratio decreased significantly before the bloom indicating a deficit in carbon ingestion and the use of storage lipid during this period, and the feeding ecology of Calanus finmarchicus was investigated.
A high-frequency time series at Ocean Weather Ship Station M (Norwegian Sea): population dynamics of Calanus finmarchicus
Between the end of March and mid-June 1997, net samples in the upper 100 m were taken almost daily on Weathership M (Norwegian Sea) to determine the abundance and stage com- position of Calanus
Life cycle of Pseudocalanus acuspes Giesbrecht (Copepoda, Calanoida) in the Central Baltic Sea: II. Reproduction, growth and secondary production
The population dynamics of Pseudocalanus acuspes in the Central Baltic Sea were studied from March 2002 to May 2003 on a monthly basis and stage durations determined from moulting experiments turned out to be extremely long.
