Predation on microcrustaceans in evidence: the role of chaoborid larvae and fish in two shallow and small Neotropical reservoirs

Nauplius
This study was focused on the predation upon microcrustaceans by an invertebrate predator (chaoborid larvae), and vertebrate predators (fish), in two small reservoirs in southeastern Brazil, with and without macrophytes, in two climatic periods (dry and ...

Scavenging Attraction of a Cyclopoid Copepod to Zooplankton Carcasses

Ecological Research, Volume 41, Issue 5, September 2026.
We experimentally demonstrated that a cyclopoid copepod, Thermocyclops taihokuensis, can function as a planktonic scavenger in freshwater ecosystems. T. taihokuensis actively approached and attacked cladoceran carcasses and was attracted to carcass‐derived chemical cues, indicating that chemical cues are key for detecting carcasses.

Long‐Term Changes in Planktonic Ciliate Beta Diversity Under Contrasting Hydrological Regulation in A River–Floodplain System

Environmental Microbiology, Volume 28, Issue 9, September 2026.
Hydrological regulation by dams reshaped ciliate biodiversity over 14 years, increasing temporal compositional change and ecological uniqueness while accelerating declines in richness and density. These results highlight flood‐pulse dynamics as a fundamental mechanism sustaining biodiversity and ecological integrity in river‐floodplain ecosystems ...

Caught Between Macrophytes and Human Impact: Zooplankton Facing Multiple Stressors in Tropical Waters

Austral Ecology, Volume 51, Issue 9, September 2026.
ABSTRACT Tropical freshwater systems host diverse and functionally important zooplankton communities that are increasingly threatened by multiple stressors. Here, we assessed how land‐use disturbance, local environmental conditions and macrophyte structure influence zooplankton richness, abundance and composition in Amazonian ponds and streams.

Spatial variations in the zooplankton community from the Corumbá Reservoir, Goiás State, in distinct hydrological periods - DOI: 10.4025/actascibiolsci.v31i3.4132

Acta Scientiarum: Biological Sciences, 2009
This study evaluated the spatial variations in species richness and abundance of zooplankton over a hydrological cycle, and also verified the influence of physical and chemical water variables and chlorophyll-α concentrations on the abundance of these ...
