Effect of polystyrene nanoplastics on its toxicity and reproduction in Philodina roseola [PDF]
Scientific ReportsMicro-nano plastics have emerged as a major ecological concern. The nanoplastics (NPs) pose a huge threat to microscopic animals. Our study aims to decipher the effect of polystyrene nanoplastics (PSNPs) of 50 and 100 nm sizes on a bdelloid rotifer ...

Local Adaptation? Enhanced Fitness Under Regional UVB Intensities in a Rock Pool Bdelloid Rotifer. [PDF]
Ecol EvolBdelloids from the Chihuahuan Desert appear to have adapted to regional UVB intensities in a localized manner. Bdelloids exposed to winter or summer levels of UVB intensity had a longer lifespan and a higher net reproductive rate. ABSTRACT Exposure to ultraviolet radiation (UVR) can decrease lifespan and reduce fecundity in aquatic invertebrates ...

Molecular Characterization of Rotifers and Their Potential Use in the Biological Control of Biomphalaria [PDF]
Frontiers in Cellular and Infection Microbiology, 2021 BackgroundSchistosomiasis is one of the most important tropical parasitic diseases worldwide. Biomphalaria straminea, the intermediate host of Schistosoma mansoni, has invaded and spread to Southern China since 1974 and may pose enormous threats to ...

Contributions of mean temperature and temperature variation to population stability and community diversity. [PDF]
Ecol Evol, 2022 Climatic changes are predicted to alter mean temperatures and fluctuations in temperature. Here, we show that increased mean temperatures are generally associated with negative impacts on biodiversity. However, these negative impacts can be partially reduced if fluctuations in temperature are maintained. Abstract Future climate changes are predicted to

Discordant spatiotemporal dynamics of functional and phylogenetic diversity of rotiferan communities exposed to aquaculture effluent. [PDF]
Ecol Evol, 2023 Effluent from aquaculture is an anthropogenic environmental burden, containing organic matter, nutrients and suspended solids that affect water quality in water bodies of high biodiversity and conservation value. Stepping beyond taxon diversity, we used functional and phylogenetic diversities of rotifera to identify factors affecting their community ...

Evaluation of Yellow Mealworm (<i>Tenebrio molitor</i>) Larvae Meal as a Carbon Source in Biofloc System for Dwarf Crayfish (<i>Cambarellus montezumae</i>) Culture. [PDF]
Aquac NutrThe aim of this study was to evaluate the use of Tenebrio molitor larvae meal as a carbon source in a biofloc system (BFT) to optimize the culture of C. montezumae. A trial was conducted for 24 weeks, 500 T. molitor larvae were reared with wheat bran as substrate, and hydration once a week; at the end, 9000 T.

Rates of Filtration and Ingestion of a Microalga by Philodina roseola (Rotifera: Bdelloidea)
Acta Biológica Colombiana, 2016 Rotifers play an important role in biogeochemical cycles and organic productivity of freshwater ecosystems due to their high metabolic rates. Information on filter feeding, their main process of energy acquisition, are relevant and still scarce for ...

Maternal age effects on offspring lifespan and reproduction vary within a species. [PDF]
Ecol EvolWe compared maternal age effects among four strains of rotifers in the Brachionus plicatilis species complex. For each strain, we measured lifespan, reproductive schedule, and lifetime reproductive output of offspring produced by young, middle‐aged, and old mothers.
