Salinity, turbidity, and chlorophyll drive zooplankton succession in a temperate estuary under anthropogenic pressure

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Estuarine zooplankton are vital primary consumers and essential for estuarine ecosystem functioning and productivity, but they face strong physico‐biochemical gradients and often anthropogenically altered habitats that impact their succession.

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 ...

Regional landscape differences lead to contrasts in the strength of environmental sorting among crustacean zooplankton metacommunities

Oikos, Volume 2026, Issue 8, August 2026.
Processes underlying metacommunity structuring are important for understanding species tracking of environmental change at a landscape scale. Species' functional traits more closely reflect their ecological roles than taxonomy, therefore, adopting a functional approach allows us a better understanding of metacommunity structuring.

Continental accumulation of fads2 copy numbers allows sticklebacks to thrive across a diversity of nutritional landscapes

Oikos, Volume 2026, Issue 8, August 2026.
Nutrients, including vital organic compounds, vary in availability across ecosystems, with the potential to act as a source of selection for traits that increase nutrient acquisition and biosynthesis. Compared to freshwaters, marine ecosystems are richer in the omega‐3 long‐chain polyunsaturated fatty acid (n‐3 LC‐PUFA) docosahexaenoic acid (DHA ...

Disentangling the Drivers of a Piscivorous Intra‐Annual Cohort and the Contributions of Three Cohorts to Early‐Year Class Strength in Pikeperch (Sander lucioperca)

Fisheries Management and Ecology, Volume 33, Issue 4, Page 784-798, August 2026.
ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

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 ...
