Ultraviolet Radiation Effects On Rotifers [PDF]
The purpose of this investigation was to study ultraviolet radiation effects on rotifers. The rotifer studied was Philodina acuticornis odiosa Milne. Isolation cultures were used to grow the rotifers individually in separate U-plate depressions.

Blooms of Microcystis aeruginosa frequently occur in many eutrophic lakes in China, however, there is very little experimental study on the relationship between Microcystis and rotifers from Chinese waters.

Permafrost thaw lakes and ponds as habitats for abundant rotifer populations
Thermokarst lakes and ponds were sampled across a range of permafrost landscapes in subarctic Québec (Nunavik, Canada) to compare their rotifer and other zooplankton characteristics with a set of rock-basin lakes and ponds in the region.

A planície de inundação do alto rio Paraná possui grande diversidade de rotíferos, com 288 táxons planctônicos registrados. Estudos realizados, nesse ecossistema, desde 1992, mostram que Lecanidae é a família mais especiosa, com 45 táxons registrados ...

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Functional Identity Drives Directional Shifts in Freshwater Plankton Biomass–Size Relationships
Normalized biomass size spectra (NBSS) for four plankton functional groups across 588 Canadian lakes. Colours correspond to each functional group; points represent the mean normalized biomass for each size bin aggregated across all lakes, ranging from 0.1 to 3.5 μm.

1. The long-term changes (1956-1998) in density and species composition of planktonic rotifers were studied at two sampling stations (I, II) of Lake Donghu, a shallow eutrophic Chinese Lake densely stocked with filter-feeding fishes.

Rotifers colonising sediments with shallow gas hydrates
Rotifers, one of the smallest metazoans, are only seldom found in marine environments. Surprisingly, we discovered high abundances of at least two new species of rotifers settling in anoxic and highly sulphidic sediments associated with shallow gas ...

ABSTRACT In temporary waterbodies such as ponds, pools and small lakes, the diversity of smaller invertebrates, such as rotifers, remains understudied, despite their ecological importance as prey and decomposers of organic matter. Especially in regions such as Israel, where natural lakes are scarce, temporary waterbodies become even more important as ...

Acanthocephalans are a small group of obligate endoparasites. They and rotifers are recently placed in a group called Syndermata. However, phylogenetic relationships within classes of acanthocephalans, and between them and rotifers, have not been well ...
