Flexible adaptation of the seasonal krill maturity cycle in the laboratory

Under controlled laboratory conditions, the influence of various light regimes onthe maturation cycle of Antarctic krill (Euphausia superba) was investigated. An acceleratedrate of maturity regression occurred when krill commenced sexualregression under complete darkness. Krill can therefore flexibl...

Description
Summary:Under controlled laboratory conditions, the influence of various light regimes onthe maturation cycle of Antarctic krill (Euphausia superba) was investigated. An acceleratedrate of maturity regression occurred when krill commenced sexualregression under complete darkness. Krill can therefore flexibly adjust their seasonalphysiological cycles to cope with varying environmental conditions.
