Bdelloid rotifers revisited [PDF]

open access: yesProceedings of the National Academy of Sciences, 2004
Sexual reproduction is one of the most striking features of the biological world. The great majority of the animals and plants with which we are most familiar reproduce at least part of the time by means of sexual reproduction with meiosis, recombination, and fertilization.

Long-term changes in the trophic state of Suwalki lakes – an analysis by means of indices based on abundance and composition of their rotifer fauna

open access: yesLimnological Review, 2016
Rotifer abundance and species composition in lakes of the Suwalki Landscape Park were studied in the years 1983–1985, 2009, 2012 and 2015. Rotifer trophic state indices (TSIROT) were used to assess changes in the trophic state of the studied lakes.

Comparison of invertebrate diversity in lake waters and their resting eggs in sediments, as revealed by high-throughput sequencing (HTS)

open access: yesKnowledge and Management of Aquatic Ecosystems, 2020
Aquatic invertebrate diversity reflects water quality and the health of aquatic ecosystems and should be monitored as an essential feature of freshwater ecosystems. The resting eggs of aquatic invertebrates in sediments populate the overlying water.

Combined effects of temperature and algal density on the life history characteristics in Brachionus angularis and Keratella Valga

open access: yesJournal of Freshwater Ecology, 2022
Temperature and food density are the most important factors influencing the population dynamics of rotifers. In the present study, the effects of temperature and food concentration on the developmental durations, egg ratio, and life-table demography in ...

Modeling the impact of rotifer contamination on microalgal production in open pond, photobioreactor and thin layer cultivation systems

open access: yesAlgal Research, 2019
Contamination of microalgal cultures by rotifers is known to cause large losses in productivity. The factors that control population dynamics of rotifers in microalgal cultures were studied in controlled contamination experiments in laboratory cultures ...

Planktonic Rotifers in a Subtropical Shallow Lake: Succession, Relationship to Environmental Factors, and Use as Bioindicators

open access: yesThe Scientific World Journal, 2013
Changes in the density and species composition of planktonic rotifers as well as their relationship to several environmental variables were studied at Dadian Lake, a shallow subtropical lake, which was completely dredged and reconstructed.

Homogenization of Functional Diversity of Rotifer Communities in Relation to Eutrophication in an Urban River of North China

open access: yesBiology, 2023
Rapid urbanization has triggered nutrient loading, which will inevitably lead to the eutrophication of water bodies and further affect the structure of aquatic populations.
