Population response of the estuarine copepod Eurytemora affinis to its bioaccumulation of trace metals

Chemosphere, 2019
We evaluated the acute toxicities of metals cadmium (Cd), copper (Cu) and nickel (Ni) to a widely-distributed copepod Eurytemora affinis isolated from the Seine estuary. Both sexes of adult E. affinis were exposed separately to the three metals at concentration gradients to determine its 50% lethal concentration (LC50).

Variation in cadmium uptake by estuarine phytoplankton and transfer to the copepod Eurytemora affinis

Marine Biology, 1999
The pathways of cadmium (Cd) uptake and transfer within an estuarine planktonic community from the Patuxent River, Maryland, USA, were investigated using an assemblage of natural phytoplankton and the copepod Eurytemora affinis Poppe. The experiment was carried out in October 1992 in replicated 500-liter, flow-through, fiberglass tanks.

Combined effects of temperature and salinity on the development of the copepod Eurytemora affinis

Aquaculture, 1992
Abstract Eurytemora affinis was cultured in 18 treatment combinations involving three temperatures (10, 15 and 20 °C) and six salinities (5, 10, 15, 20, 25 and 30 ppt). Differences in response to different combinations were not marked between naupliar and copepodite stages of development.

The Occurrence of the Calanoid Copepod Eurytemora affinis (Poppe) in the Upper Ohio River

Northeastern Naturalist, 2005
Abstract A complete record of the range of most species of zooplankton within river systems is rare. The calanoid copepod Eurytemora affinis has a relatively detailed description of its range in fresh waters, mostly because of its recent invasion into freshwater. Within the Ohio River, E.

Food uptake and growth efficiency of Eurytemora affinis (Copepoda: Calanoida)

Marine Biology, 1983
Eurytemora affinis was collected on two occasions in February and March 1981 in the Schlei Fjord, FRG, and subsequently kept in the laboratory for experiments which were conducted through April. Ingestion, assimilation and respiration of E. affinis fed with the green alga Nannochloris sp.
