Résumé :
|
Most large herbivores require some type of management within their habitats. Some populations of large herbivores are at the brink of extinction, some are under discussion for reintroduction, whilst others already occur in dense populations causing conflicts with other land use. Large herbivores are the major drivers for forming the shape and function of terrestrial ecosystems. This book addresses the scientifically based action plans to manage both the large herbivore populations and their habitats worldwide. It covers the processes by which large herbivores not only affect their environment (e.g. grazing) but are affected by it (e.g. nutrient cycling) and the management strategies required. Also discussed are new modeling techniques, which help assess integration processes in a landscape context, as well as assessing the consequences of new developments in the processes of conservation. This book will be essential reading for all involved in the management of both large herbivores and natural resources. - Provides an updated review of existing knowledge on the impact of large mammalian herbivores on species richness, ecosystem structure and function in major habitats of the world. - Gives a broad scientific and ecological background to problems related to large herbivores in different parts of the world. - Examines the conservation of herbivores themselves, and also the conservation of their habitats. The book presents the following chapters : 1. Large herbivores across biomes; 2. Living in a seasonal environment; 3. Linking functional responses and foraging behaviour to population dynamics ; 4. Impacts of large herbivores on plant community structure and dynamics ; 5. Long-term effects of herbivory on plant diversity and functional types in arid ecosystems ; 6. The influence of large herbivores on tree recruitment and forest dynamics ; 7. Large herbivores: missing partners of western-European light-demanding tree and shrub species? ; 8. Frugivory in large mammalian herbivores ; 9. Large herbivores as sources of disturbance in ecosystems ; 10. The roles of large herbivores in ecosystem nutrient cycles ; 11. Large herbivores in heterogeneous grassland ecosystems; 12. Modelling of large herbivore - vegetation interactions in a landscape context; 13. Effects of large herbivores on other fauna ; 14. The future role of large carnivores on terrestrial trophic interactions: the northern temperate view ; 15. Restoring the functions of grazed ecosystems ; 16. Themes and future directions in herbivore-ecosystem interactions and conservation.
