Download or read book Monograph of the Gonostomatidae and Kahliellidae Ciliophora Hypotricha written by Helmut Berger and published by Springer Science & Business Media. This book was released on 2011-01-06 with total page 755 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present monograph is the fourth of six volumes which review the Hypotricha, a major group of the spirotrichs. The book is about the Gonostomatidae, the Kahliellidae, and some taxa of unknown position in the hypotrichs. Gonostomum was previously misclassified in the Oxytrichidae because its type species Gonostomum affine has basically an 18-cirri pattern, which is dominant in the oxytrichids. A new hypothesis, considering also molecular data, postulates that this 18-cirri pattern evolved in the last common ancestor of the hypotrichs and therefore it appears throughout the Hypotricha tree. The simple dorsal kinety pattern, composed of only three bipolar dorsal kineties, and gene sequence analyses strongly suggest that Gonostomum branches off rather early in the phylogenetic tree. Thus, the Gonostomatidae, previously synonymised with the oxytrichids, are reactivated to include the name-bearing type genus and other genera (e.g., Paragonostomum, Wallackia, Cladotricha) which have the characteristic gonostomatid oral apparatus. The Kahliellidae are a rather vague group mainly defined via the preservation of parts of the parental infraciliature. The kahliellids preliminary comprise, besides the name-bearing type genus Kahliella, genera such as Parakahliella and its African pendant Afrokahliella or the monotypic Engelmanniella. In total 68 species distributed in 21 genera and subgenera are revised. As in the previous volumes almost all morphological, morphogenetic, molecular, faunistic, and ecological data, scattered in almost 700 papers, are compiled so that the four volumes (Oxytrichidae, Urostyloidea, Amphisiellidae and Trachelostylidae, Gonostomatidae and Kahliellida) provide a detailed insight into the biology of almost 500 species of hypotrichs. The series is an up-to-date overview about this highly interesting taxon of spirotrichous ciliates mainly addressed to taxonomists, cell biologists, ecologists, molecular biologists, and practitioners.
Download or read book Soil Biology Guide written by Daniel L. Dindal and published by John Wiley & Sons. This book was released on 1991-01-16 with total page 1381 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive study of the biology, taxonomy, and ecology of each of the soil biotic groups. The first chapter presents an ecological approach to soil studies. The remaining 42 chapters provide specific information on each of the taxonomic groupings. Contains illustrated identification keys to each group. Some keys go by functional morphological delineations; others lead the reader to classical identification at family, genus, or species levels. Some incorporate descriptions of new genera and species. Especially useful for the study of mesic, xeric, and hydric terrestrial sites. Includes an extensive bibliography.
Download or read book Monograph of the Oxytrichidae Ciliophora Hypotrichia written by Helmut Berger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1091 pages. Available in PDF, EPUB and Kindle. Book excerpt: The monophylum Oxytrichidae (Ciliophora, Hypotrichia) contains freshwater-, marine-, and soil-dwelling species. Some taxa are extremely widespread in freshwater (e.g. Oxytricha, Stylonychia) or in terrestrial habitats (e.g. Gonostomum). Oxytricha and Stylonychia have been used for many molecular, ultrastructural, and genetic investigations. This is the first book since Ehrenberg's (1838) monumental work to summarize the morphological, morphogenetic, faunistic, and ecological data from the past 220 years, scattered in more than 2500 references from all over the world. One central dichotomous key leads directly to 32 genera comprising about 169 species, which are illustrated by more than 2400 figures, including original ones. Taxonomists, ecologists, limnologists, soil biologists, and cell biologists will find a list of synonyms, a discussion of nomenclatural and taxonomic problems, and a detailed morphological and ecological description, including almost all published faunistic records. This enables both the specialist and the practitioner to determine species without referring back to the original literature. The book offers the interested scientist a thorough and up-to-date revision of the oxytrichids.

Available in PDF, EPUB and Kindle. Book excerpt: In language that is scientifically sound but accessible to the layperson, Kathleen Woida explains how Iowa's soils formed and have changed over centuries and millennia. Its soils are what make Iowa a premier agricultural state, both in terms of acres planted and bushels harvested. But in the last hundred years, large-scale intensive agriculture and urban development have severely degraded most of our soils. However, as Woida documents, some innovative Iowans are beginning to repair and regenerate their soils by treating them as the living ecosystem and vast carbon store that they are.
