We present the first faunistic report on the Laotian Cladocera from diverse habitats in Vientiane province, Central Laos. We counted a total of 70 species, belonging to 37 genera, which isExpand
Karualona n.gen. (Anomopoda: Chydoridae), with a description of two new species, and a key to all known species
The species group of Alona karua is raised to generic rank and named Karualona, and two new species are described, one from the island of Socotra and one from Mexico. Expand
Cladocerans of genus Alona Baird, 1843 (Cladocera: Anomopoda: Chydoridae) and related genera from Aguascalientes State, Mexico
Eight cladoceran species of Alona s. lato and related genera were found in Aguascalientes state, Mexico, after extensivesampling efforts. Two of them are new for science. Both new species belong toExpand
A reclassification of the anomopod families Macrothricidae and Chydoridae, with the creation of a new suborder, the Radopoda (Crustacea: Branchiopoda)
A cascade of trunk-limb based characters are derived to derive a hypothesis on the evolution of the Radopoda, and a number of unifying characters are named for all macrothricid and chydorid-like anomopods, which are united in the new suborderRadopoda. Expand
The copepod Balaenophilus manatorum (Ortíz, Lalana and Torres, 1992) (Harpacticoida), an epibiont of the Caribbean manatee
During a long-term survey on the biology and ecology of the manatee Trichechus manatus manatus L. in Mexican waters of the western Caribbean, epibionts were collected from 54 individuals, including males, females and juveniles; a comparison is made with specimens from turtles of the Mexican Pacific.

Sexual reproductive biology of twelve species of rotifers in the genera: Brachionus, Cephalodella, Collotheca, Epiphanes, Filinia, Lecane, and Trichocerca
This study challenges the common perception that mating behavior consists of five steps, and provides the first documentation of sexual cannibalism in C. catellina, and the first description of the sexual reproductive behaviors of F. ornata, F. novaezealandiae, L. nana, and T. stylata. Expand
A note on El Niagara, a polluted reservoir in Aguascalientes, Mexico
Plankton, physical, chemical, and microbiological data, were taken from the polluted reservoir El Niagara during 1990. Chlorella spp and Euglena spp were the dominant phytoplankters. ZooplanktonExpand
Ultrastructural analysis and identification of membrane proteins in the free-living amoeba Difflugia corona.
The free-living amoeba Difflugia corona was studied in relation to ultrastructure, structural membrane proteins, and proteins such as Syntaxin-1 and SNAP-25, which showed many membrane projections and several pore-like structures. Expand
Two species of Mastigodiaptomus (Copepoda: Diaptomidae), hosts of the epibiotic ciliate Trichodina diaptomi (Peritricha) in North America
The peritrich epibiotic ciliate Trichodina diaptomi Basson and Van As, 1991 was recorded on the body surface of two Neotropical species of the calanoid copepod genus Mastigodiaptomus in north-central Mexico, and recently for the first time in the Americas. Expand
First record of the temperate species Daphnia curvirostris Eylmann, 1887 emend. Johnson, 1952 (Cladocera: Daphniidae) in Mexico and its demographic characteristics in relation to algal food density
When cultured on the green alga Scenedesmus acutus at three food levels, D. curvirostris had an average lifespan that ranged from 13.5 to 17.6 days and a generation time of between 11.8 and 16.8 days, which is a new record for Mexico. Expand
