Cryptic diversification in ancient asexuals: evidence from the bdelloid rotifer Philodina flaviceps [PDF]

Journal of Evolutionary Biology, 2007
AbstractBdelloid rotifers, darwinulid ostracods and some oribatid mites have been called ‘ancient asexuals’ as they speciated and survived over long‐term evolutionary timescale without sexual recombination. Data on their genetic diversification are contrasting: within‐species diversification is present mostly at a continental scale in a parthenogenetic

Naturally Occurring Microbiota Associated with Mosquito Breeding Habitats and Their Effects on Mosquito Larvae

BioMed Research International, Volume 2020, Issue 1, 2020., 2020
Immature mosquitoes are aquatic, and their distribution, abundance, and individual fitness in a particular breeding habitat are known to be dependent on mainly three factors: biotic factors, abiotic factors, and their interaction between each other and with other associated taxa.

Evidence Supporting the Uptake and Genomic Incorporation of Environmental DNA in the “Ancient Asexual” Bdelloid Rotifer Philodina roseola

Life, 2016
Increasing evidence suggests that bdelloid rotifers regularly undergo horizontal gene transfer, apparently as a surrogate mechanism of genetic exchange in the absence of true sexual reproduction, in part because of their ability to withstand desiccation.

Antarctic bdelloid rotifers: diversity, endemism and evolution [PDF]

, 2015
Antarctica is an isolated continent whose conditions challenge the survival of living organisms. High levels of endemism are now known in many Antarctic organisms, including algae, tardigrades, nematodes and microarthropods.

How does the "ancient" asexual Philodina roseola (Rotifera: Bdelloidea) handle potential UVB-induced mutations? [PDF]

Journal of Experimental Biology, 2013
Summary Like other obligate asexuals, bdelloid rotifers are expected to suffer from degradation of their genomes through processes including the accumulation of deleterious mutations. However, sequence-based analyses in this regard remain inconclusive.

Effect of increasing salinity on the acute toxicity of a commercial endosulfan formulation to the bdelloid rotifer Philodina acuticornis odiosa

, 2011
Pesticides, such as endosulfan, can enter surface waters such as lakes and rivers, potentially posing an ecological risk. Rotifers are a dominant zooplankton species in many inland freshwater lakes in Australia; such lakes can also experience increased ...

Climatic vulnerabilities and ecological preferences of soil invertebrates across biomes. [PDF]

, 2020
Unlike plants and vertebrates, the ecological preferences, and potential vulnerabilities of soil invertebrates to environmental change, remain poorly understood in terrestrial ecosystems globally.

Zooplankton Community Composition in the White and Blue Niles Near Khartoum: Combining Molecular and Morphological Approaches

Environmental DNA, Volume 7, Issue 6, November–December 2025.
Environmental DNA (eDNA) metabarcoding of bulk zooplankton from the White and Blue Nile near Khartoum recovered 40 genus/species‐level taxa belonging to Cladocera, Copepoda, and Rotifera, representing 53%–72% of ASVs. Rotifers were the most diverse group, and low Cladocera read counts likely reflect primer mismatch despite similar morphological ...
