A major Calanus finmarchicus overwintering population inside a deep fjord in northern Norway: implications for cod larvae recruitment success

High Calanus finmarchicus abundances were recorded in wintertime in Vestfjorden, close to the main cod breeding grounds off Lofoten and Vesterålen, northern Norway. The mean abundance for locations with water depth >500 m was ∼37000 ind. m-2 (range: 26700-49000 ind. m-2). To our knowledge, this is the first report of massive overwintering of C. finmarchicus on the Norwegian shelf. Because of th...

Spatial Modeling of Calanus finmarchicus and Calanus helgolandicus: Parameter Differences Explain Differences in Biogeography

The North Atlantic copepods Calanus finmarchicus and C. helgolandicus are moving north in response to rising temperatures. Understanding the drivers of their relative geographic distributions is required in order to anticipate future changes. To explore this, we created a new spatially explicit stage-structured model of their populations throughout the North Atlantic. Recent advances in underst...

The adaptive timing of diapause – a search for evolutionarily robust strategies in Calanus finmarchicus

In environments with strong and variable seasonal fluctuations, organisms are selected on the basis of their phenology, such as the timing of diapause, reproduction, or assembling of storage products. A simulation model of the dynamic balance of various phenologies within a population facing density-dependence and varying annual, environmentally determined growth opportunities is presented. The...
