Cyclops strenuus (Fisher) is a common species of copepod in small water bodies in central Europe.[2]
The life-cycle of C. strenuus varies depending on habitat type and climate. In some habitat year round reproduction occurs. While in others one or two distinct generations exist with summer diapause.[3][4] During diapause copepodid IV resting stages are produced that are largely inactive. These resting stages can survive in mud, to survive dry summer periods. During autumn, with a change in environmental conditions, resting stages become more active again and develop further into adult copepods.[3]
Ecology[edit]
Cyclops strenuus occurs in temperate habitats. Normal activity occurs between 3 and 21 °C and temperatures above 26 °C are actively avoided.[5]
It is also a common intermediate host of cestode parasites, such as Schistocephalus solidus. When infected with this parasite reproduction of female C. strenuus is significantly reduced [6]
