Abstract Brachionus calyciflorus is a recently described monogonont rotifer species complex that comprises four species. The observation of hybridisation between two these challenges this delimitation. mechanisms reproductive isolation essential to the maintenance integrity remain unclear. Here, we conducted upscaled experiments obtain large numbers hybrid and non‐hybrid dormant propagules. Thr...

We examined population growth rate, reproduction and phosphatase activity in digestive tracts of individual Brachionus calyciflorus fed by P-replete (molar C:P 1⁄4 107) or P-depleted (C:P 1⁄4 920) algal food supplied at three carbon (C) concentrations (1, 2, and 4 mg C L). Rotifer growth rate was significantly influenced by P content, whereas the effect of algal C concentration was not signific...
