Low‐Molecular Weight Compounds that Extend the Chronological Lifespan of Yeasts, Saccharomyces cerevisiae, and Schizosaccharomyces pombe

open access: yesAdvanced Biology, Volume 8, Issue 5, May 2024.
Budding and fission yeasts are excellent model organisms for research on aging and lifespan regulation. Chronological lifespan, a definition of yeast lifespan, refers to the survival period of a cell population under nondividing conditions. In this review, the low‐molecular weight compounds are summarized that extend the chronological lifespan of ...

EST based phylogenomics of Syndermata questions monophyly of Eurotatoria

open access: yesBMC Evolutionary Biology, 2008
Background The metazoan taxon Syndermata comprising Rotifera (in the classical sense of Monogononta+Bdelloidea+Seisonidea) and Acanthocephala has raised several hypotheses connected to the phylogeny of these animal groups and the included subtaxa.

Maternal age effects on offspring lifespan and reproduction vary within a species

open access: yesEcology and Evolution, Volume 14, Issue 5, May 2024.
We compared maternal age effects among four strains of rotifers in the Brachionus plicatilis species complex. For each strain, we measured lifespan, reproductive schedule, and lifetime reproductive output of offspring produced by young, middle‐aged, and old mothers.

Individual and population variation in invertebrates revealed by Inter-simple Sequence Repeats (ISSRs)

open access: yesJournal of Insect Science, 2001
PCR-based molecular markers are well suited for questions requiring large scale surveys of plant and animal populations. Inter-simple Sequence Repeats or ISSRs are analyzed by a recently developed technique based on the amplification of the regions ...

Effects of Different Carbon Sources on the Growth and Production of Rotifer (Brachionus plicatilis) in a Zero‐Water Exchange Biofloc Culture System

open access: yesAquaculture Research, Volume 2024, Issue 1, 2024.
Brachionus plicatilis is considered an indispensable first live feed for many fish and crustacean larvae; the demand for the species has increased globally. The mass production of the rotifer involves quality microalga and a standard diet; this culture is expensive and needs a skilled workforce.
