Does “form follow function” in the rotiferan genus Keratella?
Most species of Keratella possess dome-shaped, dorsal plates comprising a network of polyhedral units (facets), delineated by slightly raised ridges. The arrangement of facets define a species’ facet pattern (FP)...

The undiscovered country: ten grand challenges in rotifer biology
Authors have attributed the statement “All science is either physics or stamp collecting” to the Physicist, Ernest Rutherford. Putting this sarcastic quip aside, we know that scientific disciplines come of age...

Motility and size of rotifers as risk factors for being consumed by the passive protistan predator Actinosphaerium sp.
Predation is a well-known factor that structures rotifer communities. However, the role of protists as predators is relatively understudied. Here, we investigated predatory behavior of Actinosphaerium sp., a fres...

Systematic distribution of birefringent bodies in Rotifera and first evidence of their ultrastructure in Acyclus inquietus (Gnesiotrocha: Collothecaceae)
Small birefringent concretions have been reported in rotifers for over a century and often hypothesized as energy sources. Here, we provide an update on their distribution in superorder Gnesiotrocha and the fi...

An examination of long-term ecological studies of rotifers: comparability of methods and results, insights into drivers of change and future research challenges
Long-term research (LTR) can provide insights into rotifer ecology that are not possible from short-term studies or experiments. However, such studies have become rarer in recent years due to budgetary constra...

When heads are not homologous: the coronae of larval and adult collothecid rotifers (Rotifera: Monogononta: Collothecaceae)
Rotifers are diverse and abundant aquatic micrometazoans that rely on their ciliated apical end (corona) for locomotion and feeding. In order Collothecaceae, which includes mostly sessile species, larval rotif...

Modeling the life history of sessile rotifers: larval substratum selection through reproduction
Although the theoretical underpinnings of habitat selection by marine invertebrate larvae have been well studied, this theory has been neglected for freshwater sessile rotifers. To study how substratum selecti...

Demography of the sessile rotifers, Limnias ceratophylli and Limnias melicerta (Rotifera: Gnesiotrocha), in relation to food (Chlorella vulgaris Beijerinck, 1890) density
We developed a simple method to culture two sessile rotifers, Limnias ceratophylli and Limnias melicerta, which should be applicable to other sessile species, and examined effect of the concentration of Chlorella...

Fifteen species in one: deciphering the Brachionus plicatilis species complex (Rotifera, Monogononta) through DNA taxonomy
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 under consideration are import...

A metadata approach to documenting sex in phylum Rotifera: diapausing embryos, males, and hatchlings from sediments
We present a survey of the literature documenting sexuality in monogonont rotifers, including reports of diapausing embryos (DEs), males, and/or hatchlings from dry sediments. Of 30 families, 27 possess specie...

Using the guild ratio to characterize pelagic rotifer communities
Ecological research is moving from a species-based to a functional-based approach to better understand the underlying principles that govern community dynamics. Studies of functional-based ecology, however, ha...

Open AccessRotifers from selected inland saline waters in the Chihuahuan Desert of México
In 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 an extensive survey of th...

Toward a Better Understanding of the Phylogeny of the Asplanchnidae (Rotifera)
We investigated the phylogenetic relationships of Family Asplanchnidae using both morphological and molecular data. The morphological database, comprising 23 characters from 19 taxa (15 Asplanchnidae and 4 out...

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) of Big Bend Nat...
