Inland Drift Sand Landscapes

Origin and History; Relief, Forest and Soil Development; Dynamics and Management

By: Josef Fanta,Henk Siepel

Man has had a complex relationship with inland drift sands through the ages. For some centuries these landscapes were seen as a threat, especially to agriculture and housing. This book considers the processes, origin, conservation and restoration of this very special but harsh biotope, one that is characterised by fields of lichens with sparse grasses and heather alongside a range of special animal, fungi and plant species. • Part 1 - Drift sand landscapes of NW Europe • Part 2 - Microclimate and soil development • Part 3 - Ecosystem succession on drift sands • Part 4 - Forestation of drift sands • Part 5 - Practical implications

Chironomidae Larvae, Vol. 3: Orthocladiinae

Biology and Ecology of the Aquatic Orthocladiinae

By: Henk K.M. Moller Pillot

Chironomidae Larvae of the Netherlands and Adjacent Lowlands Chironomids are a group of non-biting midges, the larvae of which are important in aquatic ecosystems. The subfamily Orthocladiinae is well represented in flowing water. This books contains information about their life cycle, feeding behaviour and their response to environmental factors. Chironomidae Larvae, Vol. 3: Orthocladiinae presents a wealth of information for scientific and practical purpose. The subfamily Orthocladiinae is especially well represented in flowing water. Most of the species need a good supply of oxygen and few larvae are bottom dwellers. Many species emerge early in spring and may be scarce in summer. Other species live in stagnant and even temporary water bodies. • information about the life cycle and feeding behaviour of the larvae and their response to environmental factors such as oxygen conditions, current velocity and saprobity • special attention to the interrelations between these factors • general and specific aspects of the systematics, biology and ecology the genera and species • nomenclature and identification An invaluable tool for aquatic ecologists and water quality management. Volume 1: Chironomidae Larvae - General ecology and Tanypodinae Volume 2: Chironomidae Larvae - Biology and ecology of the Chironomini Volume 3: Chironomidae Larvae - Biology and Ecology of the Aquatic Orthocladiinae

Trust in Electronic Commerce:The Role of Trust from a Legal, an Organizational, and a Technical Point of View

By: J. E. J. Prins,P. M. A. Ribbers,Henk C. A. Van Tilborg

Electronic commerce is here to stay. No matter how big the dot-com crisis was or how far the e-entrepreneurs' shares fell in the market, the fact remains that there is still confidence in electronic trading. At least it would appear that investors are confident in e-companies again. However, not only trust of venture capitalists is of importance -- consumers also have to have faith in on-line business. After all, without consumers there is no e-business. Interacting lawyers, technicians and economists are needed to create a trustworthy electronic commerce environment. To achieve this environment, thorough and inter-disciplinary research is required and that is exactly what this book is about. Researchers of the project Enabling Electronic Commerce from the Dutch universities of Tilburg and Eindhoven have chosen a number of e-topics to elaborate on trust from their point of view. This volume makes clear that the various disciplines can and will play a role in developing conditions for trust and thus contribute to a successful electronic market.
