A comprehensive study of the ecophysiology of the filamentous Meganema perideroedes affiliated to the Alphaproteobacteria, possessing a "Nostocoida limicola Type II" filamentous morphology was conducted. This morphotype often causes serious bulking problems in activated sludge wastewater treatment plants, and hardly anything is known about its physiology. The study was carried out by applying a...

Anthropogenically altered media are characterized by complex pollution, which contains a wide range of organic and inorganic pollutants, including halogen compounds. The influence halides on transformed ecosystems, in particular, their sulfidogenic photosynthetic microbiota its properties, remains insufficiently studied. sodium fluoride potassium bromide at concentrations that equal 0.5–4.0 tim...

Epimetopidae are a small beetle family of the superfamily Hydrophiloidea, comprising 72 described species in three genera: American Epimetopus Lacordaire, 1854 (56 species), Asian Eumetopus Balfour-Browne, 1949 (eight species) and African Eupotemus Ji & Jäch, 1998 species, which six as new here). In this study we illustrate compare adult morphology all genera generate first DNA sequences fo...

Ripley, S. Dillon, and Bruce M. Beehler. Rails of the World, a Compilation of New Information, 1975-1983 (Aves: Rallidae). Smithsonian Contributions to Zoology, number 417, 28 pages, 2 figures, 1985.—The senior author's monographic treatment of the Rallidae, published in 1977, was based on data available to 1975. Corrections and additions to that treatment are presented here in the form of spec...

•Two new species of flightless rails are described from a Pleistocene fauna in Bermuda that also includes an extinct crane (Grus latipes) and an extinct duck (Anas pachyscelus). The medium-sized Rallus ibycus, new species, was possibly derived from North American populations of Virginia Rail (R. limicola), but had a longer bill, much more robust legs, and reduced wings and pectoral girdle. The ...

Strains WB 3.3-2(T), WB 3.2-61(T), WB 4.1-42(T) and WB 2.3-68(T) were isolated from the Westerhöfer Bach hard water rivulet, North Germany. The strains were Gram-staining-negative and catalase-, aminopeptidase- and oxidase-positive. The novel strains lacked flagella and only strain WB3.2-61(T) showed gliding motility. Isolates WB 3.2-61(T), WB 4.1-42(T) and WB 2.3-68(T) produced flexirubin pigm...
