It is commonly used as a model organism in toxicology, ecology and evolutionary biology. Its advantages include the small size and short generation time (average generation time of B. calyciflorus is around 2.2 days at 24 °C). ReproductionB. calyciflorus normally reproduces by cyclical parthenogenesis.[1] Transitions to obligate parthenogenesis have been described. Obligate parthenogens were homozygous for a recessive allele, which caused inability to respond to the chemical signals that normally induce sexual reproduction in this species.[2] Species complexLike the Brachionus plicatilis cryptic species complex Brachionus calyciflorus seems also to be a species complex consisting of more than one species.[3][4] References1. ^http://rotifera.lifedesks.org/pages/324{{dead link|date=November 2016 |bot=InternetArchiveBot |fix-attempted=yes }} {{Taxonbar|from=Q2547210}}{{rotifer-stub}}2. ^C.-P.
