Modern Biogeochemistry : Environmental Risk Assessment

At present, quantitative ecological risk assessment is widely used in different contexts, however very often without an understanding of the natural mechanisms that drive the processes of environmental and human risk. Its application is often accompanied by high uncertainty about risk values. On the other hand, the sustainability of modern technoecosystems is known because of their natural biogeochemical cycling that has been transformed to various extents by anthropogenic studies. Accordingly our understanding of the principal mechanisms that drive the biogeochemical food webs allows us to present a quantitative ecological risk assessment and to propose technological solutions for management of various ERA enterprises. It also enables us to devise a powerful mechanism for ecological insurance, to assign responsibilities and protect rights while managing the control of damage from natural and anthropogenic accidents and catastrophes.

Modelling community structure in freshwater ecosystems

"The book presents approaches and methodologies for predicting the structure and diversity of key aquatic communities (namely diatoms, benthic macroinvertebrates and fish), under natural conditions and under man-made disturbance. Such an approach will make it possible to: 1) set up procedures for robust and sensitive ecosystem evaluation, based on the prediction of the excepted community structure; 2) model community structure in disturbed ecosystems, taking into account all the relevant ecological variables; 3) test ecosystem sensitivity to natural and anthropic disturbance; and 4) explore specific actions to be taken for the restoration of ecosystem integrity."--Jacket.

Micromammals and Macroparasites : From Evolutionary Ecology to Management

Small mammals are among the most ubiquitous and important components of terrestrial ecosystems. They have coevolved, and now coexist, with a diverse array of parasites, such that not only are all aspects of their biology influenced by parasitism but they also play key roles in the transmission and maintenance of parasitic diseases. This book provides a comprehensive survey of the diversity and biology of metazoan parasites affecting small mammals, of their impact on host individuals and populations, and of the management implications of these parasites for conservation biology and human welfare. Designed for a broad, multidisciplinary audience, it will be an essential resource for researchers, students, and practitioners alike in the fields of parasitology, evolutionary ecology, wildlife management, and conservation biology.

Microbiology of Extreme Soils

This volume provides an excellent introduction to the study of extreme soil micro-biology, and a variety of the challenging and fascinating environments that Earth-bound microbes face. Some are natural, and some are the result of human activity, and all of them have lessons to teach us about life’s adaptations within the “extreme” hori-zons of terrestrial soils. What’s more, each of these chapters (including the chapter on the soils of Mars by Ronald L. Crawford and David A. Newcombe) can give us insights into strategies that may make life possible beyond the safe confines of our present-day biosphere, to other worlds in this solar system and beyond

Microbial Root Endophytes

Plant roots may not only be colonized by mycorrhizal fungi, but also by a myriad of bacterial and fungal root endophytes that are usually not considered by the investigators of classic symbioses. This is the first book dedicated to the interactions of non-mycorrhizal microbial endophytes with plant roots. The phenotypes of these interactions can be extremely plastic, depending on environmental factors, nutritional status, genetic disposition and developmental stages of the two partners. The book deals with diversity, life history strategies, interactions, applications in agriculture and forestry, methods for isolation, cultivation, and both conventional and molecular methods for identification and detection of these endophytes. The comprehensive reviews demonstrate the high diversity of interactions and will provoke further studies to better understand the mechanisms which determine whether a plant-microbial interaction remains asymptomatic, leads to disease or to a mutualistic interaction.

Microbial Phosphate Solubilization

Last decade has seen a significantly increased knowledge about phosphate solubilizing microorganisms. Sixty specialists from thirteen countries met in Salamanca to discuss the problems of the high P-unavailability as a soil nutrient for crops, and the hazards of an increasing phosphate input to aquatic habitats from industrial and mining activities, sewage disposal, detergents, and other sources. Updated solutions to enhance P-uptake by plants, bioremediation potential in the rehabilitation of ecosystems, taxonomic characterization interactions with mycorrizae, the physiological and molecular basis of PSM, and possibilities of genetic modifications of rhizospheric microorganisms were among the contributions presented. Challenges in commercializing a phosphate solubilizing microorganism were also outlined by a relevant biotech company.

Mediterranean Island Landscapes : Natural and Cultural Approaches

Mediterranean islands exhibit many similarities in their biotic ecological, physical and environmental characteristics. There are also many differences in terms of their human colonization and current anthropogenic pressures. This book addresses in three sections these characteristics and examines the major environmental changes that the islands experienced during the Quaternary period. The first section provides details on natural and cultural factors which have shaped island landscapes. It describes the environmental and cultural changes of the Holocene and their effects on biota, as well as on the current human pressures that are now threats to the sustainability of the island communities. The second section focuses on the landscapes of the largest islands namely Sicily, Sardinia, Corsica, Cyprus, Crete, Malta and the Balearics. Each island chapter includes a special topic reflecting a particular characteristic of the island. Part three presents strategies for action towards sustainability in Mediterranean islands and concludes with a comparison between the largest islands.

Invasive forest insects, introduced forest trees, and altered ecosystems : Ecological pest management in global forests of a changing world

Demand for timber and fibre continues to grow and is being met by increased reliance on plantation forestry. Many of the plantations that are being grown around the globe are non-native species that have characteristics of rapid growth and good commercial qualities. In some cases, the high rates of production are a result of the absence of native herbivore and diseases. This limited pest status is threatened as pest species move around the globe. At the same time there is concern about threats of these non-native plantation species on native communities and the impact of changing climates on forest productivity. This volume explores many of these issues for the first time.

Integration of Information for Environmental Security : Environmental Security - Information Security - Disaster Forecast and Prevention - Water Resources Management

Currently the necessary information exists in a multitude of forms and formats geographically and physically scattered over different countries, institutes and organisations, and are subject to widely different data policies and management schemes. Moreover, there is no complete and updated overview of the existing information, e.g. in the form of a metadata catalogue. As a result, integration of this information in case of emergencies has proven to be extremely difficult, if not impossible. Although in some cases, interesting and impressive "demonstrations" have been shown of the possibilities of the integration of information, for a number of reasons these have reached the "operational" stage.
