Extensive grazing and browsing by domestic and wild herbivores shape the vegetation composition, structure and dynamics of many terrestrial ecosystems. ...
The combination of environmental stress and disturbance due to habitat instability and the possibility of periods of intense grazing impose a particularly testing blend of adverse conditions for plant survival. ...
This volume provides an overview of recent advances in the ecology of various kinds of non-forested ecosystems (grasslands, deserts, and wetlands) on a variety of topics, including species diversity and the factors that control species diversity, impacts of disturbances (grazing, mowing, fire, flooding), establishment and reproduction ecology, and plant-plant interactions. ...
During the Pleistocene, equids were the most abundant, medium-sized grazing animals of the grasslands and steppes of Africa, Asia, and the Americas. ...
Culturally the people are mostly nomadic, having been sustained for centuries by an economy based on domestic livestock grazing. There is a saying that, 'As the noses ...
One of the main objectives of nature conservation in Europe is to protect valuable cultural landscapes characterized by a mixture of open habitats and hedges, trees and patchy woodland (semi-open landscapes).The development of these landscapes during the past decades has been characterized by an ongoing intensification of land use on the one hand, and an increasing number of former meadows and ...
One of the most important distinctions to be made in relation to land degradation is between cultivated land used for annual crop production and 'rangelands'. Grazing by free-roaming livestock is the ...
They affect the livelihoods of many communities providing water, peat, timber, grazing, crops and, locally, aesthetic, cultural, recreational, nature conservation and educational benefits. ...

This book gives a comprehensive account of the methodologies for measuring methane from in vitro fermentation systems, and from stall-fed and grazing animals. The chapters have been contributed by experts in the field and methods and protocols have been presented in simple format for direct practical use. ...
The PELAG 1996 Symposium Proceedings provides the reader with the latest advances in the study of planktonic cycling of matter and energy, placing a strong emphasis on the effects of eutrophication on these processes. This book covers a wide range of topics in the field, including: Nutrient limitation of phytoplankton growth Nutrient cycles in the planktonic food web DOM sources, ...
During a forum held at the Vth IUCN World Parks Congress in South Africa in 2003, the Wildlife Conservation Society (WCS) and the IUCN SSC Veterinary and Southern Africa Sustainable Use Specialist Groups (VSG and SASUSG) brought together nearly 80 experts from Africa and beyond to develop ways to tackle the immense health-related conservation and development challenges at the wildlife/domestic ...
A little more than forty years has past since the concept of bioerosion was formally recognised as the biological erosion of hard materials. In that time, it has become apparent from the literature that bioerosional processes affect a wide range of biological and geological systems that cross many disciplines among the sciences. This book is dedicated to crossing those traditional disciplinary ...
It is a well-known fact that eutrophication of coastal waters causes significant changes in the species composition of the primary producers. Usually a shift from an ecosystem dominated by sea grasses or large brown algae to an ecosystem dominated by fast-growing green algae or phytoplankton is observed. While this shift has been documented in a number of research papers and books, the ...
Coastal habitats provide the link between the land and the sea. They are dynamic, combine to form ecosystems of great complexity and provide significant areas for wildlife. Their landscapes are treasured by visitors, painters and musicians. They also provide locations for significant economic activity and are intimately bound up with fisheries, providing food and shelter for some species of ...
This work presents the state of the art of aquatic and semi-aquatic ecological restoration projects in The Netherlands. Starting from the conceptual basis of restoration ecology, the successes and failures of hundreds of restoration projects are described. Numerous successful projects are mentioned. In general ecological restoration endeavours greatly benefit from the progressive experience ...
This book brings together a selection of original studies submitted to Biodiversity and Conservation addressing aspects of the conservation and biodiversity of plants. Plants are, along with terrestrial vertebrates, the best known organisms on Earth, and and so work on them can be a model for that on less known organism groups. Further, plants are crucial to ecosystem processes, and provide ...
The ubiquitous marine microalgal species Phaeocystis plays an important role in biogeochemical cycles. Phaeocystis has a complicated life cycle, which makes it hard to decipher the role of this organism in ecosystem dynamics and hence its role in elemental cycles. This volume offers a selection of papers that have been presented at the final meeting of Working Group # 120 "Phaeocystis, major link ...
The successful long-term sustainable management of forests is dependent on our knowledge of their history, present state, and responses to changing environmental conditions. In this light, the text evaluates the Nordic mountain birch ecosystem with examples from different sites in the Nordic countries and Scotland. The authors analyse vegetation and soils, and investigate the influence of climate ...
