Nitrite and ammonia are two of the most common toxic nitrogenous pollutants in aquatic ecosystem, which can pose a serious threat to health organisms. Cladocerans, as an important part freshwater will inevitably be harmed by these pollutants. To evaluate combined effects on cladocerans, we simulated 15 combinations five nitrite concentrations (0, 0.5, 2, 4, 8 mg L −1 ) three 0.1, 1 study change...

Daphnia pulex has played an important role in fresh-water ecosystems. In this study, the complete mitochondrial genome of Daphnia pulex from Chaohu, China was sequenced for the first time. It was accomplished using long-PCR methods and a primer-walking sequencing strategy with genus-specific primers. The mitogenome was found to be 15,306 bp in length. It contained 13 protein-coding genes, two r...

The bloom-forming, toxic cyanobacterium Microcystis synthesizes multiple secondary metabolites and has been shown to deter zooplankton grazing. However, the biochemical and/or molecular basis by which Microcystis deters zooplankton remains unclear. This global transcriptomic study explored the response of Microcystis to direct and indirect exposures to multiple densities of two cladoceran graze...

Herbicide pollution is persistent, which not only has a negative impact on individual organisms, but also may alter population dynamics and stability of interspecific relationships. Cladocerans, an important part zooplankton, are often simultaneously exposed to environmental pollutants predation risk in the aquatic environment. To evaluate combined effects atrazine fish traits cladocerans, we D...

The infestation of Rhynchopsyllus pulex on the bat Molossus molossus was observed using mist-nets opened between constructions in the Primatological Center, in Guapimirim, State of Rio de Janeiro, Brazil.

A taxonomic study of the genus Furcilarnaca Gorochov, 2004 is presented. Four new species are described: F. affinis sp. nov., F. hirta sp. nov., F. fractiflexa sp. nov., F. brachyptera sp. nov.. Two new combinations F. fallax (Liu et al., 2010) comb. nov. and F. pulex (Karny, 1928) comb. nov. are given. A key to the species and the distributional data of Furcilarnaca are provided.
