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.

Report of rotifer-ciliate-gastropod hyperepibiosis found on snail (Mollusca) from Goa, India
Acta Biologica, 2021 Here we report a rotifer-ciliate-gastropod hyperepibiosis in freshwater canal, Goa, India. A rotifer Philodina cf. megalotrocha Ehrenberg, 1832 was found attached on the colony of Epistylis plicatilis Ehrenberg, 1838 which was epibiont on gastropod ...

Influence of environmental and morphological parameters on the microfauna community present in phytotelmata of a bromeliad in a fragment of Atlantic Forest, southern Brazil [PDF]
Neotropical Biology and Conservation, 2021 Bromeliads are important epiphytes due to their abundance in the Neotropical region and morphological complexity. Their compact and imbricated leaf bases form water storage cisterns that promote important resources for colonization by several prokaryotic

New and rare taxa of freshwater zooplankton in the fauna of Yugoslavia [PDF]
Archives of Biological Sciences, 2002 Analysis of the faunistic composition of Zooplankton in two reservoirs for watersupply nearby Kragujevac indicated a relatively great diversity. Qualitative analysis of Zooplankton composition in the Grošnica reservoir demonstrated the presence of 105 ...

Molecular Ecology, Volume 32, Issue 13, Page 3497-3512, July 2023., 2023 Abstract Despite being the most important source of liquid freshwater on the planet, groundwater is severely threatened by climate change, agriculture, or industrial mining. It is thus extensively monitored for pollutants and declines in quantity. The organisms living in groundwater, however, are rarely the target of surveillance programmes and little ...

Fine structure of the retrocerebral organ in the rotifer Trichocerca similis (Monogononta)
Invertebrate Biology, Volume 142, Issue 1, March 2023., 2023 Abstract The retrocerebral organ (RCO) is a complex glandular system that is widely distributed across species of phylum Rotifera (sensu stricto). This system is hypothesized to secrete mucus that aids in benthic locomotion, adhesion, and/or reproduction.

Reduced ageing in the frozen state in the tardigrade Milnesium inceptum (Eutardigrada: Apochela)
Journal of Zoology, Volume 318, Issue 4, Page 253-259, December 2022., 2022 Tardigrades were subjected to subzero temperature treatment by cooling on agar plates from room temperature down to ‐30°C. The specimens were kept for seven days at ‐30°C without temperature fluctuations, after which the animals were allowed to slowly warm. Live and dead animals were recorded after thawing.

Food niches of planktonic rotifers: Diversification and implications
Limnology and Oceanography, Volume 67, Issue 10, Page 2218-2251, October 2022., 2022 Abstract The diverse diets of common planktonic rotifers are described in detail from field and laboratory observations and experiments. Also considered are methodological approaches, rotifer feeding mechanisms, and the availability in natural waters of less well‐known food items (detritus, picoplankton, protozoans).
