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 2006 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.

Summary
Some 50 years ago, Nature made the following observation on the issue of management of large game animals, mainly herbivores, in Africa: ‘The presence of enormous herds of game animals is quite incompatible with the economic exploitation of the country…the game must go and there can be no hope of its survival outside the National Parks…As yet, however, there is practically no information available on the biology of these mammals, information that is essential for successfully managing such parks and reserves.’ (reprinted in Nature, 431, 638, 7 October 2004). Twenty‐five years later, the first comprehensive analysis on the interaction of large herbivorous mammals and ecosystems was published (Sinclair & Norton‐Griffiths 1979). This seminal volume summarized over a decade of research by Sinclair, Norton‐Griffiths, Bell, McNaughton and their colleagues on the ecology of large mammals in the Serengeti, initiated partly in response to the situation developing in Africa that prompted Nature to make the earlier observation.
As the papers in the present volume show, current research on how large mammalian herbivores affect ecosystem properties and on the problems of their conservation extends far beyond Africa to every biome and on every continent except Antarctica. In the past 25 years since the publication of the Serengeti volume, new effects of herbivores, and new mechanisms of response of plants and ecosystems have been discovered. New mathematical theories of functional responses and herbivore‐ecosystem interactions have also been developed. The study of large mammal‐ecosystem interactions has come a long way in the past 50 years.

Summary
Large herbivores are, and have for a long time been, among the major drivers for forming the shape and function of terrestrial ecosystems. These animals may modify primary production, nutrient cycles, soil properties, fire regimes as well as other biota. Some large herbivore species/populations are at the edge of extinction and great effort is being made to save them. Other species/populations are under discussion for reintroduction. Still other species occur in dense populations and cause conflicts with other land use interests. Overall, most large herbivores need some type of management and, according to our view, these operations should be scientifically based.
There is a great amount of scientific information on large herbivores in different regions of the world. We felt that there was an urgent need to bring this knowledge together and to make it available for a larger public outside the group of specialists. We also felt that synthesis of results from one region may be valuable for scientists working in other regions and with other species.
To initiate a first synthesis of the knowledge on large herbivores we held a workshop on ‘The impact of large mammalian herbivores on biodiversity, ecosystem structure and function’ 22–26 May 2002 at Kronlund outside Umeå in northern Sweden. The event brought together scientists from different disciplines and with experience of large herbivore research in different biomes. During the workshop the idea of a book was developed over time and some more specialists were invited to the synthesis.

Summary
Biodiversity and productivity vary strongly among ecosystems: understanding the causes of these variations is a primary objective of ecology. To date a few overarching principles have been established. One is the species‐area relationship: the species diversity of a system depends principally on its area, and some major mechanisms underlying this principle have been identified (Rosenzweig 1995). The structure and dynamics of plant communities also affect biodiversity profoundly. Edaphic conditions set the bounds for plant communities, and fire can be a key determinant of their structure and diversity. In addition, at least in some ecosystems, large herbivores are ‘keystone’ species, so the systems have very different structures according to whether large herbivores are present or absent. There is also some evidence that large herbivores affect plant productivity, from modelling (de Mazancourt et al. 1998) as well as empirical work (McNaughton 1985).
Understanding the role of large herbivores is therefore important for ecology, and also because the abundance of these animals can have profound effects on the conservation status of other species, through their impact on plant communities. However, the literature on these questions is rather difficult to access especially for people who are not academic ecologists. Reviewing the impact of large herbivores on ecosystems was identified as a priority in the Action Plan for the Large Herbivore Initiative for Europe and Central Asia (see http://www.largeherbivore.org). In some areas the ungulate populations are ‘overabundant’ and have serious negative impacts on forestry, agriculture and biodiversity.

Summary
INTRODUCTION
The question of how herbivores control various ecosystem processes has had a long history in modern ecology. In a now much‐cited paper, Hairston et al. (1960) proposed that in the absence of predators, herbivore populations increase to the limit set by their food supply and thus control net or actual productivity and energy flow. With the addition of predators, herbivore populations become controlled from above; plant productivity is then released from direct control by herbivores and instead is limited by abiotic processes such as climate. These ideas have been developed further by Oksanen and colleagues (Oksanen et al. 1981, Oksanen 1983, 1988). In order to simplify the concepts and models, these studies have ignored the way that the cycling of nutrients between decomposers and higher trophic levels limits net primary productivity in most ecosystems, and the many mechanisms by which herbivores alter nutrient flows through decomposers and soils.
Early recognition of the roles of herbivores in regulating nutrient cycles focused on phytophagous insects (Mattson & Addy 1975) or phytoplanktivorous zooplankton (Kitchell et al. 1979). Perhaps this was because of their ubiquity, rapid population growth rates, high turnover rates and because (at least in the case of zooplankton) they consume most of the primary production (Macfadyen 1964). With the exception of large herds in grasslands (Sinclair & Norton‐Griffiths 1979) and microtine populations in tundra (Schultz 1964), the possibility that mammals could also regulate nutrient cycles was generally ignored for quite some time.

From the emission line map in Hα over the full face of the spiral galaxy NGC 3359, we analyze the internal velocity structure of the H ii region population. The emission line profiles show central peaks, with turbulent velocity widths of ≤20 km s–1, and also broad shallow wings, with typical velocities of ~50 km s–1, with respect to the rest velocity of the H ii region. We verify the identification of these wings as due to expanding gas, quantify the energy involved, and suggest physical models for their interpretation, as the effects of mechanical and radiative outflows from the central OB stellar cluster.

Summary
Introduction
In this chapter we will examine the nature of the southern boreal forest, explicitly its transition with the cool temperate deciduous forest that occurs to its south. Although this mixed deciduous and conifer forest occurs on portions of several continents in the northern hemisphere, it is most intact and most studied in North America as the northern hardwood and conifer biome (Braun 1950; Curtis 1959). Therefore, although we will describe this zone in other regions, we will concentrate on the North American expression of it. For convenience, we will also adopt the shortened common name ‘northern hardwoods’ for the cool temperate and largely deciduous forest to the south while recognizing that certain conifers are also important components of this forest.
The southern boreal forest contains extreme contrasts in ecosystem properties corresponding to the locations of different species within a mosaic landscape. These properties are accentuated at its boundary with the northern hardwoods and conifers, which are transitional to the deciduous forests to the south. Within these two biomes, each genus, and in some cases different species within each genus, affects ecosystem properties in different ways. Such properties include nutrient cycling and productivity, disturbance type and frequency, and suitability as an animal habitat. Consequently, there are strong feedbacks between succession, species dominance, resource limitation, disturbance regimes, and trophic structure (Fig. 8.1). These feedbacks may be stabilizing or destabilizing, the latter often causing cycles at various times and in various places.
