Interactive Effects of Hypoxia and Temperature on Coastal Pelagic Zooplankton and Fish
Hypoxia, triggered in large part by eutrophication, exerts widespread and expanding stress on coastal ecosystems. Hypoxia is often specifically defined as water having dissolved oxygen (DO) concentrations < 2 mg L-1.

To study the proximal factors inducing diel vertical migration (DVM) in large and small zooplankton species in a plateau lake in China, we investigated the DVM of crustacean zooplankton in lake Erhai bimonthly from November 2009 to September 2010.

A remarkable early sea-ice reduction event was observed in the northern Bering Sea during 2018. In turn, this unusual hydrographic phenomenon affected several marine trophic levels, resulting in delayed phytoplankton blooms, phytoplankton community ...

Cleaner Fish Labroides dimidiatus Presence Does Not Indirectly Affect Demersal Zooplankton
Coral reef mutualisms involve complex trophic ecological relationships that produce indirect effects. Excluding mutualistic cleaner fish Labroides dimidiatus from reefs indirectly increases the abundance of many fishes and reduces demersal stages of ...

Evaluation of marine zooplankton community structure through environmental DNA metabarcoding
Zooplankton dominate the abundance and biomass of multicellular animals in pelagic marine environments; however, traditional methods to characterize zooplankton communities are invasive and laborious. This study compares zooplankton taxonomic composition

Ocean deoxygenation and zooplankton: Very small oxygen differences matter
Novel midwater ocean sampling shows that physiology dictates zooplankton distributions in submesoscale low oxygen features. Oxygen minimum zones (OMZs), large midwater regions of very low oxygen, are expected to expand as a result of climate change ...

Zooplankton and Micronekton Active Flux Across the Tropical and Subtropical Atlantic Ocean
Quantification of the actual amount of carbon export to the mesopelagic layer by both zooplankton and micronekton is at present a gap in the knowledge of the biological pump.

Zooplankton Biomass in Ponds - Determination of Biovolume and Dry Weight
The aim of this study was to evaluate the possibility of using simple screening methods to determine zooplankton biomass in ponds. Among the applicable methods, we selected sedimentation determination of wet biomass and dry biomass determination.
