Daphnia lumholtzi
Daphnia lumholtzi
(a waterflea)

Impact ID8388
Impact TypeCompetition
Study TypeExperimental
Study LocationLaboratory
Impact DescriptionIn competitive experiments between Daphnia lumholtzi and Great Lakes native D. pulex, tanks with mixed populations, D. lumholtzi productivity dropped to 55% of its control value, while D. pulex productivity dropped to just 17% of its control value. Combined productivity of the daphnids dropped by over 50%, indicating that D. lumholtzi could facilitate competitive exploitation and adversely impact the overall productivity of the zooplankton community.
Great Lakes RegionNo
