This volume is the result of a Symposium, held in October, 1985, to celebrate the Silver Jubilee of the De partment of Plant Ecology of the University of Groningen. The Department of Plant Ecology was founded by Professor Dingeman Bakker and has, since its incep tion, been involved with studies of grasslands, and especially with the effects of human interference on grassland communities. It has been especially involved in an almost unique enterprise to convert areas of grassland from intensive agricultural production to nature reserves. With over-production of most food commodities in the EEC, and increasing interest in various types of 'set aside' schemes, this initiative now seems to be remarkably prescient. The Netherlands have a long history of human manipulation of the environment. Indeed, the Dutch en vironment is probably more man-made than that of any other country. In view of this, and the Laborato ry's interest in managed grasslands, it is not surprising that 'Disturbance in Grasslands' was selected as the topic for the Laboratory's Jubilee Symposium. Although both the Symposium and the resulting vo lume, have a strong Dutch component, the organisers invited a number of contributors from Europe and elsewhere to provide key chapters. The result is a volume which covers many aspects of disturbance in a variety of grasslands. Disturbance is considered at both the community and the population level, and the principles and processes underlying those responses are explored.

Grasses and Grassland Ecology provides an ecologically orientated introduction to this influential group of plants, summarizing the most recent scientific research in ecology and agriculture in the context of the older, classic literature. Ten chapters cover the morphology, anatomy, physiology and systematics of grasses, their population, community and ecosystem ecology, their global distribution, and the effects of disturbanceand grassland management.

"Genetic diversity and species diversity are both crucial for ecosystem stability. Analysis of plant diversity aims to understand the organization and the variability of biological populations within ecosystems. This book provides a review on chemotaxonomical criteria helping to understand complex structures of plant diversity. It focuses particularly on the chemotaxonomic usefulness of phenolic compounds in analysis of chemical polymorphisms at different taxonomic levels. The relationship between grazing pressure and grassland vegetation is also examined, using drastically improved information technology such as remote sensing, Geographic Information System (GIS) and Ground Positioning Systems (GPS). Furthermore, an overview of the unique ecosystem of the South Brazilian Campos grasslands are given. The role of disturbance in maintaining Campos biodiversity and dynamics, and the importance of its conservation, is looked at as well. Other chapters in this book discuss the relationship between management and vegetation, and also suggest ways to conserve the species diversity of both plants and butterflies in semi-natural grassland."--Publisher's description.

This practical manual covers habitat management for invertebrates, drawing on the experience of years of work by many specialists. Invertebrates are much more sensitive than plants or vertebrates are to habitat changes, and their needs are not always being met, even on nature reserves. This book provides guidelines on how to take account of the vulnerable and important habitat features, without necessarily knowing what species are present.

Although fires favor herbaceous plants at the expense of woody plants, woody plant dominance on many sites precludes the deliberate application of fire without first using chemical or mechanical treatments. Climate change is perhaps the most critical factor facing the current generation of land managers who are concerned about the future condition of borderlands ecosystems. Rising concentrations of CO2 and other trace gases have the potential to replace grazing and fire suppression as important regulators of vegetation change. Increased atmospheric CO2 concentrations may contribute to increased abundance of woody plants in borderlands grasslands, particularly if these increases are accompanied by shifts in seasonal precipitation or other climatic factors. Much of the knowledge garnered about borderlands plant communities is derived from descriptive research such as comparative studies and "natural" experiments.

There is growing concern over the conservation and management of European wet grasslands. The maintenance of the European wet grassland landscape, including floodplain meadows and coastal grazing marshes or pastures, through traditional low-intensity farming has conserved a habit supporting internationally important plant and animal communities, including many rare species. However,land use changes such as flood defence, land drainage, agricultural intensification and neglect have caused a considerable reduction in the extent and biodiversity of European wet grasslands. The international importance of the habitat for biodiversity conservation has recently been recognised with its inclusion in the European Union Habitats and Species Directive and the Convention on Biological Diversity fostered by the United Nations. This volume thoroughly examines European perspectives of wet grassland ecology in order to encourage an integrated approach to contemporary issues. Important topics covered include the status of wet grasslands in Europe, their biodiversity (plants, invertebrates and birds), hydrology and management (especially for conservation objectives), and the restoration of this threatened habitat. It combines prescriptive, analytical and reviewing contributions, including case studies from across Europe. As such, this book will appeal equally to academic institutions and professional practitioners.

This introductory general ecology text features a strong emphasis on helping students grasp the main concepts of ecology while keeping the presentation more applied than theoretical. An evolutionary perspective forms the foundation of the entire discussion. The book begins with the natural history of the planet, considers portions of the whole in the middle chapters, and ends with another perspective of the entire planet in the concluding chapter. Its unique organization of focusing only on several key concepts in each chapter sets it apart from the competition. .

Ecosystems of Disturbed Ground

As the human population inexorably grows, its cumulative impact on the Earth's resources is hard to ignore. The ability of the Earth to support more humans is dependent on the ability of humans to manage natural resources wisely. Because disturbance alters resource levels, effective management requires understanding of the ecology of disturbance. This book is the first to take a global approach to the description of both natural and anthropogenic disturbance regimes that physically impact the ground. Natural disturbances such as erosion, volcanoes, wind, herbivory, flooding and drought plus anthropogenic disturbances such as foresty, grazing, mining, urbanization and military actions are considered. Both disturbance impacts and the biotic recovery are addressed as well as the interactions of different types of disturbance. Other chapters cover processes that are important to the understanding of disturbance of all types including soil processes, nutrient cycles, primary productivity, succession, animal behaviour and competition. Humans react to disturbances by avoiding, exacerbating, or restoring them or by passing environmental legislation. All of these issues are covered in this book. Managers need better predictive models and robust data-collections that help determine both site-specfic and generalized responses to disturbance. Multiple disturbances have a complex effect on both physical and biotic processes as they interact. This book provides a wealth of detail about the process of disturbance and recovery as well as a synthesis of the current state of knowledge about disturbance theory, with extensive documentation.
