Available in PDF, EPUB and Kindle. Book excerpt: Time-variable exposure profiles of pesticides are more often the rule than exception in the surface waters of agricultural landscapes. There is, therefore, a need to adequately address the uncertainties arising from time-variable exposure profiles in the aquatic risk assessment procedure for pesticides. Linking Aquatic Exposure and Effects: Risk As

Download or read book The Everglades Experiments written by Curtis Richardson and published by Springer Science & Business Media. This book was released on 2008-03-12 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Florida Everglades ecosystem is recognised world-wide as a significant wetland whose natural processes have been altered and remain threatened. State and Federal US agencies face critical decisions about the course of conservation and restoration efforts. Synthesising nearly ten years of laboratory and field research of the Duke University Wetland Center, this book provides the long-term integrated scientific studies needed to understand the functioning of this region. Background information about the current and historical ecological conditions of the region set the context for reports of long-term research projects, while a series of gradient studies determine the effects of hydrology and nutrient changes. Subsequent sections present models for predicting responses to various conditions and analyse the studies and models, focusing on management and restoration of the Everglades.

Download or read book Monitoring Wilderness Stream Ecosystems written by and published by . This book was released on 2001 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: A protocol and methods for monitoring the major physical, chemical, and biological components of stream ecosystems are presented. The monitoring protocol is organized into four stages. At stage 1 information is obtained on a basic set of parameters that describe stream ecosystems. Each following stage builds upon stage 1 by increasing the number of parameters and the detail and frequency of the measurements. Stage 4 supplements analyses of stream biotic structure with measurements of stream function: carbon and nutrient processes. Standard methods are presented that were selected or modified through extensive field application for use in remote settings.

Available in PDF, EPUB and Kindle. Book excerpt: For the first time in limnofaunistic bibliography, the present taxonomic knowledge about the different clades of chelicerata having adapted to an aquatic or amphibious lifestyle along various evolutionary pathways is brought together in an overview for the Central-European fauna. A total number of 746 taxa is covered, over 99 % of these at species level. In Volume 7/2-1 altogether 211 species are treated - 70 species of spiders, 7 species of Astigmata (3 of which to be identified only at family, genus, resp. species group level), 17 species of Oribatida, 27 species and one subspecies of Halacaridae, 45 species of terrestrial Parasitengona (4 of which to be identified only at genus level) and 45 species of Hydrachnidia (4 Stygothrombioidea, 3 Hydrovolzioidea, 16 Hydrachnoidea and 22 Eylaoidea). Volume 7/2-2 deals with 179 species of Hydrachnidia (58 Hydryphantoidea and 121 Lebertioidea). This third volume (Volume 7/2-3) includes taxonomic keys and ecological information for 355 species of the two highly diverse Hydrachnidia superfamilies Hygrobatoidea (241 species and one subspecies) and Arrenuroidea (113 species). The chelicerata volumes of this series are a basic tool for all limnologists interested in diversity and ecology – in particular for biologists investigating the ecotones between ground and surface water, between bottom substrata and open water, and between water and land.
