Metapopulation Dynamics: Empirical and Theoretical Investigations by Michael Gilpin Pdf

Metapopulation Dynamics: Empirical and Theoretical Investigations covers the 1989 proceedings of a metapopulation dynamics workshop held at Lammi Biological Station, Helsinki, Finland. It is divided into 18 chapters that cover various approaches to spatially structured population and community dynamics. After briefly discussing the history of metapopulation ideas and the major conceptual links, the book covers types of studies that have been conducted on single-species and multispecies metapopulations. Then, it examines the relationships between metapopulation dynamics, the equilibrium theory of island biogeography, and the dynamics of populations living in patchy environments. It further tackles practical issues and the links between metapopulation dynamics and landscape ecology, and between metapopulation dynamics and conservation biology. Chapters 4 and 5 present structured models describing changes in the number of individuals within patches and an empirical evaluation of local extinction in metapopulation studies. The subsequent chapters discuss several aspects of metapopulation, including dispersal and connectivity, colonization, conspecific attraction, extinction and isolation, and forest fragmentation. The latter chapters describe the concept of habitat fragmentation, the diversity and competition in metapopulations, the community collapse, and the effects of metapopulation studies in predator-prey systems.

Connectivity Conservation by Kevin R. Crooks,M. Sanjayan Pdf

One of the biggest threats to the survival of many plant and animal species is the destruction or fragmentation of their natural habitats. The conservation of landscape connections, where animals, plants, and ecological processes can move freely from one habitat to another, is therefore an essential part of any new conservation or environmental protection plan. In practice, however, maintaining, creating, and protecting connectivity in our increasingly dissected world is a daunting challenge. This fascinating volume provides a synthesis on the current status and literature of connectivity conservation research and implementation. It shows the challenges involved in applying existing knowledge to real-world examples and highlights areas in need of further study. Containing contributions from leading scientists and practitioners, this topical and thought-provoking volume will be essential reading for graduate students, researchers, and practitioners working in conservation biology and natural resource management.

Species Survival in Fragmented Landscapes by J. Settele,Chris Margules,Peter Poschlod,Klaus Henle Pdf

The effects of isolation, area size, and habitat quality on the survival of animal and plant populations in the cultural landscape are central aspects of a research project started in Germany in 1993 (,Forschungsverbund, Isolation, FHichengroBe und BiotopquaIiHit', abbreviated to 'FIFB'). After a long period of preparation, scientists from seven univer sities and one research institution started to work within the frame of this project. Fund ing for four years was provided by the former German Federal Ministry of Research and Technology (BMFT), now the Ministry of Education and Research (BMBF). A strong focus of the project has been the improvement of the methodology for environmental impact assessments and the implementation of results into environmental planning. As there is a certain risk that national projects develop some kind of 'mental in breeding', it was decided to discuss concepts, methods, and first results with scientists of international reputation at a rather early stage of the project. For this purpose, an inter national workshop was held in the small village of Lubast, north of Leipzig (state of Saxony) in March 1995. 130 scientists from 10 nations met to discuss and debate issues surrounding habitat fragmentation for three days. Papers presented there formed the basis for this book. As discussions included general reviews as well as particular case studies, we decided to structure this book in a similar way. Consequently, a combination of broad and more general, review-like papers as well as original papers are presented.

Entomology at the Land Grant University by Kevin M. Heinz,Raymond E. Frisbie,Carlos E. Bográn Pdf

Insects affect the health and well-being of humans every day, everywhere, so the entomology departments that study them make a crucial contribution to many aspects of life. Indeed, agricultural success in the United States and other countries depends upon the work of entomology departments within the land grant system at universities across the nation. Entomology at the Land Grant University is a thorough look at how entomology departments have adapted to shifting demographics, changes in land use patterns, environmental issues, and advances in the life sciences. It also highlights the leadership of entomologists in their multifaceted roles as researchers, teachers, and consultants. With world-renowned contributors from both academia and industry, this volume is the culmination of a series of mini-symposia celebrating the 100th anniversary of the Department of Entomology at Texas A&M University. The centenary was a time to reflect on past accomplishments and to plan for future challenges, spotlighting the academic, scientific, economic, and social importance of entomology. The result is a broad-brushed picture of a discipline that at its best represents the highest virtues of fundamental and applied science, with topics such as: - fulfilling the land grant university mission - roles of entomology departments - the function of the extension service - the global reach of entomological research - civic education in insect management - genetic engineering - future innovations in pest management and insecticide design Not just for entomologists, this insightful look into the workings of a university department within the context of a rapidly changing scientific, social, and economic climate will appeal to anyone associated with a land grant university, extension or regulatory agency, or related industry.

Theoretical Approaches to Biological Control by Bradford A. Hawkins,Howard V. Cornell Pdf

Biological control is the suppression of pest populations using predators, parasitoids and pathogens. Historically, biological control has largely been on a trial-and-error basis, and has failed more often than it has succeeded. However by developing theories based upon fundamental population principles and the biological characteristics of the pest and agent, we can gain a much better understanding of when and how to use biological control. This book gathers together recent theoretical developments and provides a balanced guide to the important issues that need to be considered in applying ecological theory to biological control. It will be a source of productive and stimulating thought for all those interested in pest management, theoretical ecology and population biology.

Reintroduction of Top-Order Predators by Matt W. Hayward,Michael Somers Pdf

Large predators are among the most threatened species on the planet and ways of conserving them in the face of increasing human populations and associated resource requirements are becoming critical. This book draws upon the experiences of some of the world’s foremost large carnivore specialists to discuss the numerous issues associated reintroducing large predators back into their natural habitats. Reviews of internationally renowned reintroduction programs for wolves, European lynx and African wild dog reveal the successes and failures of these actions. Experts on tigers, snow leopards and jaguars contend that there are other conservation options of higher priority that will ensure their security in the long-term. Other experts discuss more theoretical aspects such as whether we know enough about these species to be able to predict their behavioural or ecological response to the reintroduction process. Social, economic, political and genetic considerations are also addressed.

Consumer-Resource Dynamics (MPB-36) by William W. Murdoch,Cheryl J. Briggs,Roger M. Nisbet Pdf

Despite often violent fluctuations in nature, species extinction is rare. California red scale, a potentially devastating pest of citrus, has been suppressed for fifty years in California to extremely low yet stable densities by its controlling parasitoid. Some larch budmoth populations undergo extreme cycles; others never cycle. In Consumer-Resource Dynamics, William Murdoch, Cherie Briggs, and Roger Nisbet use these and numerous other biological examples to lay the groundwork for a unifying theory applicable to predator-prey, parasitoid-host, and other consumer-resource interactions. Throughout, the focus is on how the properties of real organisms affect population dynamics. The core of the book synthesizes and extends the authors' own models involving insect parasitoids and their hosts, and explores in depth how consumer species compete for a dynamic resource. The emerging general consumer-resource theory accounts for how consumers respond to differences among individuals in the resource population. From here the authors move to other models of consumer-resource dynamics and population dynamics in general. Consideration of empirical examples, key concepts, and a necessary review of simple models is followed by examination of spatial processes affecting dynamics, and of implications for biological control of pest organisms. The book establishes the coherence and broad applicability of consumer-resource theory and connects it to single-species dynamics. It closes by stressing the theory's value as a hierarchy of models that allows both generality and testability in the field.

The Spatial and Temporal Dynamics of Host-Parasitoid Interactions by Michael Hassell Pdf

This book examines our current understanding of the population dynamics of one kind of interaction - that between insect parasitoids and their hosts. Parasitoids are amongst the most abundant of all animals, and make up about 10% or more of metazoan species. Almost no insect species escape their attack. Host-parasitoid interactions were first modelled over fifty years ago, but for many years there was little good empirical information on the important factors that affect host and parasitoid populations. The models were very simple, and their predictions rather divorced from the complexity of what was visible in the field. Now, better data is available on many components of host-parasitoid systems, from field observations and laboratory and field experiments, and this allows a much closer correspondence between models and data. In particular, the past twenty years have seen major advances in our understanding of how host-parasitoid interactions are influenced by spatial processes, by age-structure effects, and by competition from additional host and parasitoid species. The result is a body of theory that makes direct contact with real systems in the field, and provides us with a detailed understanding of what underpins a whole area of population dynamics. In this book, Michael P Hassell pulls the theory and field data together to present an elegant illustration of the way in which ecological studies advance.

Principles and Methods in Landscape Ecology by Almo Farina Pdf

This third, thoroughly updated edition of a well received book, presents the most complete collection of theories, paradigms and methods utilized by the landscape sciences. With the introduction of new ecosemiotic concepts and innovative managing procedures, it offers a broad list of ecological, ecosemiotical and cultural tools to investigate, interpret and manage the environmental complexity according to a species-specific individual-based approach. Readers will discover the importance of a landscape perspective to create strategic bridges between science and humanities favored by the holistic sight of sensorial (visual, acoustic, olfactory, tactile, and thermal) “scapes”. Distributed in 10 chapters, the content covers many aspects of the landscape sciences ranging from the description of fundamental theories, principles and models originated by ecological approaches like source-sink models, island biogeography, hierarchical theory and scale. The ecosemiotical approaches like the eco-field model, the ecoscape paradigm, and the general theory of resources are widely described and discussed. A cultural approach to landscape is utilized to focus on the heritage values of territories and their environmental identity. This book, written in an accessible and didactic style, is particularly dedicated to undergraduate and graduate students but also scholars in ecology, agroforestry, urban planning, nature design, conservation and remediation. Land practitioners, farmers and policymakers can use this book as an authoritative guide to better understand the function and role of environmental systems according to a social-economic integrated perspective.
