Brachionus calyciflorus is a species complex: Mating behavior and genetic differentiation among four geographically isolated strains
Four geographic strains of B. calyciflorus are investigated regarding their genetic similarity and ability to cross-mate. DNA sequence analysis of the mitochondrial cox1 gene (694 bp) and the nuclearExpand

Rotifers Ingest Oocysts of Cryptosporidium parvum
Abstract Six genera of rotifers including Philodina, Monostyla, Epiphanes, Euchlanis, Brachionus, and Asplanchna were exposed to oocysts of Cryptosporidium parvum cleaned of fecal debris. UnstainedExpand

Life on the Edge: Rotifers From Springs and Ephemeral Waters in the Chihuahuan Desert, Big Bend National Park (Texas, USA)
Here we describe an on-going study of the rotifers inhabiting a sampling of springs (seeps), streams, ponds, tanks (diked ephemeral streams), and huecos and tinajas (small and large rock pools) ofExpand

Sexual reproduction and diapause of Hexarthra sp. (Rotifera) in short‐lived ponds in the Chihuahuan Desert
SUMMARY 1. In the life cycle of monogonont rotifers it is generally assumed that diapausing eggs invariably hatch into amictic stem females which produce female offspring parthenogenetically.Expand

Interaction effects of multi-metal solutions (As, Cr, Cu, Ni, Pb and Zn) on life history traits in the rotifer Plationus patulus
While many studies have determined toxicity of single heavy metals, few have addressed the combined effects of multiple elements at different concentrations. In order to estimate how metal mixturesExpand
