Habitat Characteristics Of Eurytemora Lacustris (Poppe, 1887) (Copepoda, Calanoida): The Role Of Lake Depth, Temperature, Oxygen Concentration And Light Intensity

Field observations, laboratory experiments and a literature survey were conducted to evaluate the habitat characteristics of Eurytemora lacustris (POPPE 1887), a freshwater calanoid copepod species. Combined effects of temperature and oxygen concentration in the deep water of thermally stratifying lakes seem to be the ultimate factors governing the occurrence of the species throughout its home-territory. E. lacustris is largely restricted to relatively deep lakes (> 30 m) providing a hypolimnetic refuge characterised by low temperatures (更多
