Trans-Generational Morphological Trait Plasticity in Parthenogenetic Offspring of Two <i>Brachionus dorcas</i> Morphotypes Induced by <i>Asplanchna</i> Kairomones. [PDF]

open access: yesEcol Evol
We compared life‐table parameters and trans‐generation (F0–F12) morphological developmental plasticity induced by Asplanchna kairomones between two Brachionus dorcas morphotypes (long‐posterior spines, LS; short‐posterior spines, SS). The results revealed that the SS offspring employed a synergistic defense combining increased body size and spine ...

Effect of Brachionus rubens on the growth characteristics of various species of microalgae

open access: yesElectronic Journal of Biotechnology, 2016
Background: Cultivation of algae for conversion to biofuels has gained global interest. Outdoor raceway cultivation is preferred because of its lower capital and operating costs.

The significance of phosphorus in algae growth and the subsequent ecological response of consumers

open access: yesJournal of Freshwater Ecology, 2022
Human activities have substantially disrupted phosphorus (P) cycles in the ecosystem, affecting producers and consumers along the food chain. To assess the ecological effects of imbalanced P on producers as well as consumer reactions to changes in food ...

Free Amino Acid Enriched Rotifer for Larval Grouper Cromileptes altivelis (Pengkayaan Rotifer dengan Asam Amino Bebas Untuk Larva Kerapu Bebek Cromileptes altivelis)

open access: yesIlmu Kelautan, 2015
Pembenihan ikan kerapu dihadapkan pada rendahnya sintasan, terutama fase awal hidupnya. Rendahnya sintasan diduga berhubungan dengan belum berkembangnya organ pencernaan larva dan tidak tersedianya pakan yang siap diserap tubuh.

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 ...

The importance of environmental differences in the structuring of rotifer functional diversity

open access: yesJournal of Limnology, 2019
A dynamic change in environmental conditions among floodplain habitats with different geomorphology might be a significant trigger in determining rotifer functional diversity.

Rotifers: Exquisite Metazoans [PDF]

open access: yesIntegrative and Comparative Biology, 2002
Rotifers comprise a modestly sized phylum (≈1,850 species) of tiny (ca. 50-2,000 μm), bilaterally symmetrical, eutelic metazoans, traditionally grouped within the pseudocoelomates or Aschelminthes. These saccate to cylindrically shaped protostomes possess three prominent regions (corona, trunk, foot).

A Preliminary Study on the Effects of Taurine-Enriched Rotifers on the Growth and Survival of the Small Yellow Croaker Larimichthys polyactis Larvae

open access: yesAnimals, 2022
The effect of feeding with taurine-enriched rotifers on larval growth and survival in the small yellow croaker Larimichthys polyactis was investigated. Rotifers, control (without taurine enrichment) or enriched with a commercial taurine supplement at two

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.
