Download or read book Aquatic Oligochaetes written by Brenda M. Healy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book contains papers on the biology of aquatic oligochaetes and some related groups. They cover a wide range of topics including phylogeny, taxonomy, geographic distribution, freshwater and marine ecology, population dynamics, histology and ultrastructure, physiology and behaviour. The wide scope is in line with recent trends in annelid research with less emphasis on pollution studies and faunistics and a renewed interest in experimental biology using new techniques.

Download or read book Agricultural Ecology and Environment written by B.R. Stinner and published by Elsevier. This book was released on 2012-12-02 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increased use of chemical fertilizers and pesticides in crop production has adversely affected both the environment and the agricultural economy. Not only has it led to environmental pollution, but also the increasing costs of chemical inputs and the low prices received for agricultural products have contributed to economic unprofitability and instability.The International Symposium on Agricultural Ecology and Environment was organised in order to discuss ways of achieving the goals of economically and environmentally sustainable agriculture. It is apparent that a truly multidisciplinary effort is required and for this reason the meeting was attended by authors from many different disciplines and geographical locations. Although their papers reflect a wide diversity of agroecosystem types and examples, several common themes emerge: the increased importance of biotic control of ecosystem processes in lower input systems; the key role of soil organic matter in stabilizing nutrient cycling; the importance of agricultural landscape diversity and complexity; the importance of studying ecological processes in natural and agricultural ecosystems; the critical need to integrate socio-economic and ecological approaches.
Download or read book Treatise on Zoology Anatomy Taxonomy Biology The Gregarines 2 vols written by Isabelle Desportes and published by BRILL. This book was released on 2013-05-23 with total page 793 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phylum Apicomplexa is characterized by the unique cell organisation of the zoites, the infective stages of unicellular parasites previously designated as Sporozoa. Apicomplexa includes Coccidian and Hematozoa well known for human and veterinary diseases they cause, such as malaria, toxoplasmosis, babesiosis, coccidiosis, and the large group of Gregarines, the early branching Apicomplexa. Gregarines are parasite of invertebrates and urochordates and they performed an extraordinary radiation from the marine and terrestrial hosts known from the Cambrian biodiversity explosion. After the basic publication in the Traité de Zoologie by Grassé in 1953, this second edition updates the knowledge with information provided by new technologies such as electron microscopy, biochemistry and molecular biology and to enlighten their high diversity of adaptation to invertebrate hosts living in a diversity of biotopes. The extracellular development of Gregarines, the considerable diversification of their cell cortex, their wide distribution in Annelids, Crustaceans, Echinoderms, Myriapods or Insects with about hundred thousands of species contribute to the understanding of many biological aspects of the pathogenic Apicomplexa. Since 1953, taxonomical reviews on Gregarines were published in the Illustrated Guide of Protozoa. In this supplement, there is a special emphasis on the hosts. Contributors include: Stuart Goldstein, Ryoko Kuriyama, Gérard Prensier, Jiri Vavra, Lawrence Howard Bannister, Jean François Dubremetz. Without the financial support of academic and non-profit organisations the edition of this volume would not have been possible.
