: Dynamics of Large Herbivore Populations in Changing Environments: Towards Appropriate Models (): Owen-Smith, Norman: BooksCited by: About this book.

This book aims to reconcile theoretical models of population dynamics with what is currently known about the population dynamics of large mammalian herbivores.

It arose from a working group Dynamics of large herbivore populations in changing environments book at the National Center for Ecological Analysis and Synthesis at the University of California, Santa Barbara, to address the need for models that better accommodate environmental variability, especially for herbivores dependent on changing.

The contents provide a foundation for resolving problems of diminishing large mammal populations in Africa, over-abundant ungulate populations elsewhere, and general consequences of global change for biodiversity conservation. This book will serve as a definitive outline of what is currently known about the population dynamics of large herbivores.

[Norman Owen-Smith; National Center for Ecological Analysis and Synthesis.;] -- This book aims to reconcile theoretical models of population dynamics with what is currently known about the population dynamics of large mammalian herbivores.

Vera () and Olff et al. () also mention that a prerequisite for the (re-)establishment of thorny shrubs in the created grasslands is a temporary reduction of the large herbivore populations.

Whether self-regulating large herbivores do indeed play a key role in wood-pasture landscapes, however, remains an unanswered question (Vera, Dynamics of large herbivore populations in changing environments: towards appropriate models.

[R Norman Owen-Smith; National Center for Ecological Analysis and Synthesis.;] -- This text aims to reconcile theoretical models of population dynamics with what is currently known about the population dynamics of large mammalian herbivores.

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.

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.

Book description. The adaptation of herbivore behaviour to seasonal and locational variations in vegetation quantity and quality is inadequately modelled by conventional methods. Norman Owen-Smith innovatively links the principles of adaptive behaviour to their consequences for population dynamics and community ecology, through the application of a metaphysiological modelling approach.

Abstract This paper considers the conceptual basis of large herbivore population dynamics. Carrying capacity is discussed in its many meanings, and K -carrying capacity, the maximum number of animals an area will support based on resources, is suggested as the basic meaning of the term.

The world's populations of large herbivores have shown dramatically different dynamics during the last two decades. The abundance and distribution of some ungulate species has declined abruptly, while other species have become excessively abundant, and still others have shown complex, oscillatory dynamics.

These shortcomings do not greatly distract from the value of this book. Overall, Large Herbivore Ecology, Ecosystem Dynamics and Conservation provides a very good overview of large mammal impacts on ecological processes and species in terrestrial systems, particularly for northern temperate and boreal systems.

From an operational point of view, his research is based on long-term monitoring of large herbivore populations to explore how human induced environmental change (e.g.

landscape modification, phenology, climate warming, hunting) influences their population dynamics. Plants are attacked by many different consumers. A critical question is how often, and under what conditions, common reductions in growth, fecundity or even survival that occur due to herbivory translate to meaningful impacts on abundance, distribution or dynamics of plant populations.

understanding the population dynamics of large herbivores and their impacts on natural resources. Density-dependent and density-independent drivers of large herbivore population dynamics An understanding of what factors cause animal popula-tions to increase, decrease or remain stable is fundamental to the provision of advice on how to manage them.

The main focus is on large mammalian herbivores occupying seasonally variable environments such as those characterized by African savannas, but applications to temperate zone ungulates are also included.

Issues of habitat suitability, species coexistence, and population stability or instability are similarly : R. Norman Owen-Smith. Changes in the Environment The carrying capacity can change when the environment changes.

For example, after a rainy season, plants may produce a large crop of leaves and seeds. This large amount of food may allow an herbivore population to grow. But what if important resources are destroyed. A population crash occurs when the carrying capacity.

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.

This method for studying natural populations became widely adopted, and was a force which developed enormous research energy in the s.

Insect population dynamics became a major focus in ecology, and a flush of books soon reflected this interest (e.g., Referen 38, and ). This book presents, for the first time, a collection of studies on the ecology of the rich and diverse large herbivore assemblages of South and Southeast Asia.

Written by experts on herbivores of the region, it covers a comprehensive range of topics, including their evolutionary history, behaviour. In several ungulate species, the effects of climate on population dynamics occur only at high population densities (e.g., Grenfell et al.Jacobson et al.

This is unsurprising, given that resource stress is the primary source of negative climatic effect on populations, and larger populations are more likely to confront resource.

Large Herbivore Ecology, Ecosystem Dynamics and Conservation is a very readable book for beginners and specialists alike who wish to broaden their knowledge of the effects of large herbivores on ecosystem dynamics.' Basic and Applied Ecology Book Description. Some large herbivore species are rare, others are s: 1.

Abstract. Large-mammal herbivore populations are subject to the interaction of internal density-dependent processes and external environmental stochasticity. We disentangle these processes by linking consumer population dynamics, in a highly stochastic environment, to the.

One hump dynamics indicate an optimal population. A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding.

Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant. Large herbivore population dynamics are generally influenced by a combination of stochastic environmental variation and population density (Saether, ).

Unmanaged or minimally managed populations should be expected to fluctuate about some mean tendency in quasiequilibrium, and the degree of fluctuation will depend on the degree of climatic.

For 30 years, Owen‐Smith has made significant. -The heavy pant growth stimulated large increases in herbivores The great increase in land plant biomass and insect abundance are indicative of an important change in the dynamics of this system.

Previously most material flowing through the food webs of the islands originated directly or. Introduction. How to manage species and environments for the benefits of conservation, economic, and human well-being objectives is a central challenge facing management can often involve population control where humans intervene to reduce population size in a range of species, for example to eradicate invasive species and limit the population of agricultural pests.Global Trophic Cascades Program is a research and educational program with the purpose of investigating the role of predators in structuring ecological communities.

This program puts special emphasis on the role of potential keystone species in top-down community regulation, with linkages to biodiversity via trophic cascades. This loss has been attributed to the increase in human population, dumping of waste water, soil erosion and subsequent sediment input by rivers, eutrophication, imbalance of food chains, proliferation of macroalgae [65,], diseases and climate change [, ], as well as the removal or decimation of top predators and large herbivores.
