Effects of L-Carnitine on Growth of Individually Cultured Cladoceran, Moina micrura
The cladoceran, Moina micrura, is a potential alternative live food for fish larvae. The effects of L-carnitine enrichment on first reproduction age, population density, and growth rate in M. micrura were determined. The cladocerans were enriched at 10 levels of L-carnitine (0, 0.001, 0.01, 0.1, 1, 10, 100, 500, 1000, and 1500 mg/l) dissolved in 30 ml Chlorella vulgaris culture medium for 17 da...
متن کاملEffect of butyl benzyl phthalate on life table-demography of two successive generations of cladoceran Moina macrocopa Straus.
In this study, the acute toxicity of butyl benzyl phthalate (BBP) to freshwater cladoceran Moina macrocopa was tested, and its chronic effects on survival and reproduction of two successive generations of the cladoceran were studied using life-table demographic method. The results showed that the 48-hr LC50 of BBP for M. macrocopa was 3.69 mg l(-1). Compared to the blank controls, BBP at 125, 5...
متن کاملTransgenerational epigenetic inheritance: more questions than answers.
Epigenetic modifications are widely accepted as playing a critical role in the regulation of gene expression and thereby contributing to the determination of the phenotype of multicellular organisms. In general, these marks are cleared and re-established each generation, but there have been reports in a number of model organisms that at some loci in the genome this clearing is incomplete. This ...
متن کاملTwo-step dialogue between the cladoceran Bosmina and invertebrate predators: Induction and natural selection
Aquatic prey species respond to predators with fast (developmental) and slow (selective) feedbacks. Natural selection is assumed to fashion details of induction and to modify baseline morphology, but only rarely do we catch the slower (multi-generation) process in action. Laboratory experiments with Bosmina detected predatormediated induction and estimated spine heritability (h2 5 0.2–0.5). Thi...
متن کاملCan there be more predators than prey?
One of the few general “theorems” of ecology is the statement that in a given habitat there can be no more species present than the number of limiting resources. Our aim is to examine several of the versions of this “theorem” present in the literature, to compare them and to consider the underlying assumptions and definitions so as to decide to what ecological situations the theorem is applicab...
