- n. One of the Cladocera.
For example, in the freshwater cladoceran Daphnia spp., growth rates are correlated with the concentration of eicosapentaenoic acid in the water column .
Likewise, diatom and cladoceran evidence suggest dry warm summers during the period dominated by pine (~7,000 – 3,500 years BP).
Functional ecology and palaeolimnology: using cladoceran remains to reconstruct anthropogenic impact.
In the European Arctic, combined evidence from oxygen isotope and pollen-inferred precipitation records, cladoceran-inferred lake levels, diatom-inferred lake-water ionic strength, and elemental flux records of erosion intensity into lakes, all suggest more oceanic conditions in the region during the early part of the Holocene than today, with a shift towards drier conditions between approximately 6,000 and 4,500 years BP .
The very dry period corresponding to shifts from birch to pine corresponds to increasing frequency of diatom and cladoceran taxa indicating lake-level reduction and vegetation overgrowth of numerous lakes .
Daphnia retrocurva, a common cladoceran in the Great Lakes of North America, has a rounded head from fall to early spring.
One of the most obvious features of a cladoceran is its single, large compound eye.
Under high P: Si ratios, the increased time between phytoplankton and cladoceran peaks opened a loophole for filamentous cyanobacteria (Oscillatoriales) in warm years to establish dominance after the diatoms, which are silicate limited.
Overall, the cladoceran, D. pulex has a wide range of CYPs with the same clans as insects and nematodes, but with distinct changes in the size and composition of each clan.
Chydorus - Chydorus is a cladoceran, a group of tiny crustaceans, most of which live in fresh water.
