Application of COI Primers 30F/885R in Rotifers to Regional Species Diversity in (Sub)Tropical China
Diversity, 2021 Rotifers are the most diverse group in freshwater zooplankton and play an important role in food webs and ecosystems. DNA barcoding has become a useful approach to investigate species diversity at local and regional scales, but its application is still ...

Dietary Value of Waste-Fed Rotifer Brachionus rotundiformis on the Larval Rearing of Japanese Whiting Sillago japonica [PDF]
E3S Web of Conferences, 2020 Live food resources are useful for larval fish rearing. However, production of sufficient live food resources is expensive. This study employed a cost-effective rotifer culture technique using fish waste diet (FWD) and investigate the effect of the FWD ...

Environmental science and pollution research international, 2017 Lecane inermis rotifers were shown to diminish sludge bulking due to their ability to ingest the filamentous bacteria in activated sludge. To determine if rotifers are also able to control branched actinomycetes, we investigated three other Lecane ...

Effect of large- and small- bodied zooplankton on phytoplankton in a eutrophic oxbow [PDF]
, 2005 Macrozooplankton and microzooplankton effects on the phytoplankton were measured in situ in a eutrophic lake. Indigenous phytoplankton were incubated for 5 days in 301 mesocosms with either the macro- and microzooplankton (complete), microzooplankton ...

Under-ice environmental conditions, planktonic communities and ichthyofauna in dystrophic lakes
The European Zoological Journal, 2021 High content of humic substances and low pH values are factors limiting the species richness and abundance of some organisms in dystrophic lakes. Unfavourable winter conditions (i.e.

Developmental Dynamics, EarlyView.Abstract Background To understand cellular morphology, biologists have relied on traditional optical microscopy of tissues combined with tissue clearing protocols to image structures deep within tissues. Unfortunately, these protocols often struggle to retain cell boundary markers, especially at high enough resolutions necessary for precise cell ...

Improvements on Live Feed Enrichments for Pikeperch (Sander lucioperca) Larval Culture
Animals, 2020 This study focused on supplementing pikeperch (Sander lucioperca) larvae with rotifers fed with Chlorella vulgaris during the first 15 days post hatching (dph).

Improved COI taxonomic assignment workflow enhances detection of invertebrates in environmental DNA
Limnology and Oceanography: Methods, EarlyView.Abstract Environmental DNA (eDNA) metabarcoding is an increasingly popular and powerful tool in ecology, offering a non‐invasive method to assess biodiversity and monitor ecosystem health across diverse environments. While the mitochondrial cytochrome c oxidase subunit I (COI) gene is one of the most widely used markers for studying eukaryotic ...
