Effects of NaCl salinity on the population dynamics of freshwater zooplankton (rotifers and cladocerans)
TLDR
Under laboratory conditions, the effect of different salt concentrations (0–4.5 g l−1) on the population dynamics of ten freshwater zooplankton species and the rates of population increase were generally higher for rotifers than for cladocerans.
Lifetable demography of four cladoceran species in relation to algal food (Chlorella vulgaris) density
TLDR
This work studied the life table demography of four cladoceran species in relation to three algal food concentrations and concluded that among the algal concentrations used here, 0.5 × 106 – 1.5× 106 was beneficial not only to the planktonic species but also to the littoral P. aduncus and S. vetulus while 4.
Life history strategies of cladocerans: comparisons of tropical and temperate taxa
TLDR
The possibility of encountering the tropical cladocerans in the northern, temperate hemisphere (bioinvasions) is on the rise, in direct response to changes in the behaviour, distribution, and abundance of cladOCerans.
Phylogenetic Relationships of Acanthocephala Based on Analysis of 18S Ribosomal RNA Gene Sequences
TLDR
Analysis of the nearly complete 18S rRNA genes of nine species from the three classes of Acanthocephala and four species ofRotifera found statistically significant support for the monophyly of Rotifera, represented in the analysis byspecies from the clade Eurotatoria, which includes the classes Bdelloidea and Monogononta.
Population growth of some genera of cladocerans (Cladocera) in relation to algal food (Chlorella vulgaris) levels
TLDR
It became evident that for up to 1300 μm body size, the threshold food level increased with increasing body size; however, beyond this, thereshold level decreased supporting earlier observations on rotifers and large cladocerans.
Review of Recent Ecotoxicological Studies on Cladocerans
TLDR
The effect of different toxic substances on cladocerans based on both the field and the laboratory studies from an ecotoxicology point of view is reviewed.
Demographic parameters of Brachionus patulus Muller (Rotifera) exposed to sublethal DDT concentrations at low and high food levels
TLDR
The average lifespan, life expectancy, net reproductive rate (Ro) and intrinsic rate of increase (r) were significantly greater at the higher food level, but declined with increasing DDT concentration, while a significant DDT food interaction was manifested in the toxicity-mitigating action of theHigher food density at higher DDT levels.
Life history strategies of cladocerans: comparisons of tropical and temperate taxa
We review recent works on different life history variables of cladoceran taxa in tropical and temperate freshwater bodies, comparing the strategies that cladocerans have evolved to adapt to
Comparative Life Table Demography and Population Growth of Brachionus macracanthus DADAY, 1905 and Platyias quadricornis EHRENBERG, 1832 (Rotifera, Brachionidae) in Relation to Algal (Chlorella
TLDR
The observed differences in the life history variables of both the rotifer species in relation to food level have been interpreted in terms of species-specific adaptations, based on a combination of life table demography and population growth parameters.
Seasonal Variations in the Species Diversity of Planktonic Rotifers in Lake Xochimilco, Mexico
ABSTRACT We collected rotifers during one year (2002–2003) from four different sites in Lake Xochimilco and analyzed the species diversity. We found on an average 25–30 species co-existing at any one
