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

Fifteen species in one: deciphering the Brachionus plicatilis species complex (Rotifera, Monogononta) through DNA taxonomy
Abstract Understanding patterns and processes in biological diversity is a critical task given current and rapid environmental change. Such knowledge is even more essential when the taxa underExpand

Cryptic speciation in the cosmopolitan Epiphanes senta complex (Monogononta, Rotifera) with the description of new species
Many rotifers are considered to be cosmopolitan species including Epiphanes senta, which has been reported from all continents including Antarctica. To determine the potential for cryptic speciationExpand

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

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

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

How well do single samples reflect rotifer species diversity? A test based on interannual variation of rotifer communities in Big Bend National Park (Texas, USA)
Studies of rotifer community composition and dynamics often rely on limited sampling regimes. To determine how well species richness is reflected in these studies, we examined interannual variationExpand

Assessment of arsenic and heavy metal concentrations in water and sediments of the Rio Grande at El Paso-Juarez metroplex region.
The Rio Grande located along the US-Mexico border is affected by anthropogenic activities along its geographical course. Runoff and wind deposition of smelting residues may contribute to theExpand

Rotifers from selected inland saline waters in the Chihuahuan Desert of México
BackgroundIn spite of considerable efforts over past decades we still know relatively little regarding the biogeography of rotifers of inland waters in México. To help rectify this we undertook anExpand
