Download or read book The semi aquatic freshwater earthworms of the genus Glyphidrilus Horst 1889 from Thailand Oligochaeta Almidae with re descriptions of several species written by Ratmanee Chanabun and published by PenSoft Publishers LTD. This book was released on 2012-02-06 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten new species of semi-aquatic earthworm genus Glyphidrilus Horst, 1889 are described from several river systems in Thailand. The earthworms were all found at a depth of 5?15 cm from the surface in wet top soil and usually near casts. The worms excrete casts on the soil surface by locating the tails up to the soil surface while the heads go down to deeper soils. They have the peculiar expanded epidermis at about clitellum position called ?wings? which function is still unknown. They produce long cocoons wich locate vertically in the soil in the same places as the worms. One cocoon produces 7-10 juveniles. All the ten new described species appear to be highly endemic to particular watershed with very little range overlap between them, and most are confined to a small region. The lowland paddy systems in Thailand have been colonized by some species of Glyphidrilus, where they occur in the rice paddy throughout the propagation period (wet season) from planting of the seedlings to post harvest (dry season). The worms did well in areas of organic farming and so are likely to be sensitive to modern agrochemical contamination of the environment.

Download or read book Earthworm Ecology and Biogeography in North America written by Paul F. Hendrix and published by CRC Press. This book was released on 1995-02-22 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is generally recognized that where earthworms are abundant they can exert significant influence on the structure and function of soils. Compared to other biogeographic regions of Earth, however, surprisingly little is known about the earthworm fauna of the western hemisphere and their role in soil processes. This book is the first comprehensive review and analysis of the state of understanding of earthworm biogeography and ecology in North America. Topics of in-depth discussion include earthworm systematics, biogeography and ecology, influences on soil structure and ecosystem nutrient dynamics, and implications for ecosystem management. Each chapter provides a general review and statement of current understanding, an assessment of current research problems, recent developments and advances, and priorities for future research and applications. This book is a must for researchers and students studying the soil-related facets of terrestrial ecology.

Download or read book Earthworm Ecology written by J. Satchell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Darwin cleared: official' This 1982 Times (7 January) head line of a first leader, reporting the astonishing case brought in Arkansas against compulsory teaching of a biblical account of creation, hopefully set at rest doubts about Darwin in the minds of a public confused by media presentations of such unfamiliar concepts as punctuated equilibria, cladism and phenetics. Mud sticks, but Darwin's perturbed ghost may have found some consolation in the concurrent celebrations at Grange-over-Sands, a modest township in Cumbria, UK, of the centenary of the publication of his less controversial book The Formation of Vegetable Mould through the Action of Worms. In the form of a symposium on earthworm ecology, this attracted some 150 participants, predominantly adrenalin-charged research workers in the full heat of peer-group interaction. This book comprises a selection of the more ecologically oriented papers contributed to the symposium, brutally edited in the interests of brevity and thematic continuity. The book opens with an appraisal of Darwin's earthworm work in its historical and philosophical context and relates his views on 'vegetable mould' to current concepts of humus formation. Thereafter, quotations from Darwin made out of piety have been rigorously excluded. Subsequent sections each comprise a review chapter and two or three 'case studies' presenting new data on a related topic.
