Book excerpt: The fusion of individualistic community ecology with the Hutchinsonian niche concept enabled a broad integration of ecological theory, spanning all the way from the niche characteristics of individual species, to the composition, structure, and dynamics of ecological communities. Landscape ecology has been variously described as the study of the structure, function, and management of large heterogeneous land areas. Any reading of the published landscape ecology literature shows near uniformity in the adoption of a categorical patch-mosaic paradigm. However, if biological communities are multivariate gradients of species composition, with each species responding individualistically to particular combinations of limiting factors, is a categorical patch-based representation appropriate? We evaluate the sufficiency of several patch-based representations of vegetation at the landscape level to explain the composition of the plant community. Classified vegetation maps all performed poorly in explaining the composition and structure of forest trees among plots. Different categorical vegetation maps provided largely independent explanations of species variability. Individual species models based on spectral, topographic, and climatic variables vastly out-performed those produced using the classified maps. By moving from a landscape ecological paradigm based on categorical patches to one based on quantitative species and environmental responses across continuous space, it will be possible to both produce much more effective predictions of species distributions and ecological processes and remove much of the disjunction between landscape ecology and mainstream community ecology theory.

Available in PDF, EPUB and Kindle. Book excerpt: People are constantly changing the land surface through construction, agriculture, energy production, and other activities. Changes both in how land is used by people (land use) and in the vegetation, rock, buildings, and other physical material that cover the Earth's surface (land cover) can be described and future land change can be projected using land-change models (LCMs). LCMs are a key means for understanding how humans are reshaping the Earth's surface in the past and present, for forecasting future landscape conditions, and for developing policies to manage our use of resources and the environment at scales ranging from an individual parcel of land in a city to vast expanses of forests around the world. Advancing Land Change Modeling: Opportunities and Research Requirements describes various LCM approaches, suggests guidance for their appropriate application, and makes recommendations to improve the integration of observation strategies into the models. This report provides a summary and evaluation of several modeling approaches, and their theoretical and empirical underpinnings, relative to complex land-change dynamics and processes, and identifies several opportunities for further advancing the science, data, and cyberinfrastructure involved in the LCM enterprise. Because of the numerous models available, the report focuses on describing the categories of approaches used along with selected examples, rather than providing a review of specific models. Additionally, because all modeling approaches have relative strengths and weaknesses, the report compares these relative to different purposes. Advancing Land Change Modeling's recommendations for assessment of future data and research needs will enable model outputs to better assist the science, policy, and decisionsupport communities.

Available in PDF, EPUB and Kindle. Book excerpt: Cultural landscapes are usually understood within physical geography as those transformed by human action. As human influence on the earth increases, advances in palaeocological reconstruction have also allowed for new interpretations of the evidence for the earliest human impacts on the environment. It is essential that such evidence is examined in the context of modern trends in social sciences and humanities. This stimulating new book argues that convergence of the two approaches can provide a more holistic understanding of long-term physical and human processes. Split into two major sections, this book attempts to bridge the gap between the sciences and humanities. The first section, provides an analysis of the methodological tools employed in examining processes of environmental change. Empirical research in the fields of palaecology and Quaternary studies is combined with the latest theoretical views of nature and landscape occurring in cultural geography, archaeology and anthropology. The author examines the way in which environmental management decisions are made. The book then moves on to discuss the relevance of this perspective to contemporary issues through a wide variety of international case studies, including World Heritage protection, landscape preservation, indigenous people and cultural tourism.

Available in PDF, EPUB and Kindle. Book excerpt: The first edition of Toward a Unified Ecology was ahead of its time. For the second edition, the authors present a new synthesis of their core ideas on evaluating communities, organisms, populations, biomes, models, and management. The book now places greater emphasis on post-normal critiques, cognizant of ever-present observer values in the system. The problem it addresses is how to work holistically on complex things that cannot be defined, and this book continues to build an approach to the problem of scaling in ecosystems. Provoked by complexity theory, the authors add a whole new chapter on the central role of narrative in science and how models improve them. The book takes data and modeling seriously, with a sophisticated philosophy of science.

Available in PDF, EPUB and Kindle. Book excerpt: This book is intended to provide information to those who wish to interact with the landbase in an ecologically sustainable manner. Practitioners charged with the administration of land-based programs in industry and government will find the information presented useful. It should also be a resource for many community groups involved in land-use decision-making. Humans continue to use forests and make decisions about land use without perfect information. Conservation Biology Principles for Forested Landscapes is intended to enable the improvement of planning and decison-making processes by providing ecological information on issues of forest use. Current approaches are not working. Where information exists on new, ecologically sustainable approaches, practitioners should switch. Where the information on a better approach is not yet available, practitioners should replace the current, inappropriate approach with a variety of flexible ones that offer the opportunity to change with new knowledge.

Book excerpt: This strategy integrates knowledge, research, and management approaches from landscape ecology into conservation management of land over the next 20 years. The strategy considers the operational approaches of database accumulation, field experiments, and management applications. The report provides general recommendations; strategic program recommendations, including Ontario landscape database analysis and landscape protection and reconstitution applied to Ontario; and gives examples of focal projects in landscape reconstitution, including the St. Lawrence lowlands region in Southern Ontario, Great Lakes-St. Lawrence forest region transition zone, and the Canadian Shield region boreal forest.

Book excerpt: Wildlife species across the globe face a dire predicament as their traditional migratory routes are cut off by human encroachment and they are forced into smaller and smaller patches of habitat. As key species populations dwindle, ecosystems lose resilience and face collapse, and along with them, the ecosystem services we depend on. Healthy ecosystems need healthy wildlife populations. One possible answer? Wildlife corridors that connect fragmented landscapes. This second edition of Corridor Ecology: Linking Landscapes for Biodiversity Conservation and Climate Adaptation captures advances in the field over the past ten years. It features a new chapter on marine corridors and the effects of climate change on habitat, as well as a discussion of corridors in the air for migrating flying species. Practitioners, land managers, and scholars of ecology will find it an indispensable resource.
