How to Develop and Organize a Classification Essay.
A minority of rare species were of pelagic origin, especially rotifers of the family Brachionidae, e.g., Brachionus falcatus, B. polyacanthus, B. leydigi, or Keratella paludosa, while littoral-associated taxa prevailed. This also confirms the major role of vegetated zones in even very small water bodies in increasing the overall biodiversity, and particularly supporting the occurrence of.
Rotifer (Brachionus calyciflorus) One of the most beautiful microscopic organisms, rotifers are little princesses with magic crowns. FACTS: Rotifers are beautiful microscopic creatures most commonly found in freshwater environments. They are among the smallest members of the animal kingdom, and have delighted amateur microbiologists since their.
Experiments with two strains of the facultative epibiont, Brachionus rubens, tested the ability of this rotifer to avoid predation by the rotifer Asplanchna, and its propensity for sexual reproduction and consequent diapause at different population densities. Unlike some congeners, B. rubens did not have a morphological response to Asplanchna by developing longer spines or a larger body.

Abstract. A review of temperature and salinity effects on rotifer population dynamics is presented together with original data of these effects for three clones of Brachionus plicatilis.There is a clear relationship between temperature and the intrinsic rate of increase, r: an increase of temperature — within the natural environmental range — produces an exponential increase of r, and the.
Antonyms for classification include disorganisation, disorganization, keeping, retention, disorder, disarrangement, disorderliness, chaos, unemployment and imbalance.
Monogononta is the most speciose class of rotifers, with more than 2,000 species. The monogonont genus Brachionus is widely distributed at a global scale, and a few of its species are commonly used as ecological and evolutionary models to address questions related to aquatic ecology, cryptic speciation, evolutionary ecology, the evolution of sex and ecotoxicology.
