Butterfly Conservation in North America

Butterfly Conservation in North America PDF Author: Jaret C Daniels
Publisher: Springer
ISBN: 9401798524
Category : Nature
Languages : en
Pages : 195

Book Description
The book addresses this critical need by providing a straightforward and easy to read primer to key elements of at-risk butterfly conservation programs including captive husbandry, organism reintroduction, habitat restoration, population monitoring, recovery planning and cooperative programs. Impacts from habitat loss and fragmentation, invasive species, and climate change continue to accelerate the rate of imperilment and necessitate increased conservation action. Zoos, natural history museums, botanical gardens and wildlife agencies are progressively focusing on insects, particularly charismatic groups such as butterflies and native pollinators, to help advance local conservation efforts and foster increased community interest and engagement. Today, many institutions and their partners have successfully initiated at-risk butterfly conservation programs, and numerous others are exploring ways to become involved. However, insufficient experience and familiarity with insects is a critical constraint preventing staff and institutions from adequately planning, implementing and evaluating organism-targeted activities. The information provided is intended to improve staff practices, learn from existing programs, promote broader information exchange, and strengthen institutional ability to develop new or improve existing butterfly conservation initiatives. The information provided is intended to improve staff practices, learn from existing programs, promote broader information exchange, and strengthen institutional ability to develop new or improve existing butterfly conservation initiatives. This book will be useful to professionals from zoos, natural history museums, botanical gardens, wildlife agencies, conservation organizations, land managers, students, and scientist in conservation biology, ecology, entomology, biology, and zoology.

Dispersal Ecology and Evolution

Dispersal Ecology and Evolution PDF Author: Jean Clobert
Publisher: OUP Oxford
ISBN: 0191640360
Category : Science
Languages : en
Pages : 496

Book Description
Now that so many ecosystems face rapid and major environmental change, the ability of species to respond to these changes by dispersing or moving between different patches of habitat can be crucial to ensuring their survival. Understanding dispersal has become key to understanding how populations may persist. Dispersal Ecology and Evolution provides a timely and wide-ranging overview of the fast expanding field of dispersal ecology, incorporating the very latest research. The causes, mechanisms, and consequences of dispersal at the individual, population, species, and community levels are considered. Perspectives and insights are offered from the fields of evolution, behavioural ecology, conservation biology, and genetics. Throughout the book theoretical approaches are combined with empirical data, and care has been taken to include examples from as wide a range of species as possible - both plant and animal.

A Resource-Based Habitat View for Conservation

A Resource-Based Habitat View for Conservation PDF Author: Roger L. H. Dennis
Publisher: John Wiley & Sons
ISBN: 1444315269
Category : Science
Languages : en
Pages : 420

Book Description
Winner of the Marsh Book of the Year Award 2012 by theBritish Ecological Society. In A Resource-Based Habitat View for Conservation RogerDennis introduces a novel approach to the understanding of habitatsbased on resources and conditions required by organisms and theiraccess to them, a quantum shift from simplistic andineffectual notions of habitats as vegetation units or biotopes. Indrawing attention to what organisms actually use and need inlandscapes, it focuses on resource composition, structure andconnectedness, all of which describe habitat quality and underpinlandscape heterogeneity. This contrasts with the current bipolarview of landscapes made up of habitat patches and empty matrix butillustrates how such a metapopulation approach of isolatedpatchworks can grow by adopting the new habitat viewpoint. The book explores principles underlying this newdefinition of habitat, and the impact of habitat components onpopulations, species’ distributions, geographical ranges andrange changes, with a view to conserving resources in landscapesfor whole communities. It does this using the example ofbutterflies - the most alluring of insects, flagship organisms andkey indicators of environmental health - in the British Isles,where they have been studied most intensively. The book formsessential reading for students, researchers and practitioners inecology and conservation, particularly those concerned withmanaging sites and landscapes for wildlife.

From the Corn Belt to the Gulf PDF Author: Joan I Nassauer
Publisher: Taylor & Francis
ISBN: 1136525351
Category : Law
Languages : en
Pages : 274

Book Description
Nutrients from farms in the Mississippi River Basin are the leading cause of the Gulf of Mexico‘s 'Dead Zone,' a 5,000 to 7,000 square mile region where declining oxygen levels are threatening the survival of marine life. From the Corn Belt to the Gulf explores how new agricultural policy can help alleviate this problem, and at the same time improve water quality overall, enhance biodiversity, improve the quality of life for the people who live and work in Corn Belt communities, and relieve downstream flooding. The themes of the book are the far-reaching environmental impacts of Corn Belt agriculture, including associated economic and social effects at multiple spatial scales - and the potential for future agricultural policy to address those impacts through changes in agricultural landscapes and practices. We know that the environmental 'footprint' of Corn Belt agriculture extends beyond farmland and adjacent lakes and streams to groundwater, rivers, cities downstream, into the Gulf of Mexico, and, ultimately, to global oceanic and atmospheric systems. And we acknowledge that agricultural policies, including commodity support payments, have economic impacts at the national and international levels. Pressing negotiations with America‘s trade partners, along with increasing societal attention to both the costs and environmental effects of current agricultural policy, are creating momentum for policy change. From the Corn Belt to the Gulf presents innovative, integrated assessments of the agriculture and ecological systems in the Mississippi River Basin along with studies of local Iowa agricultural watersheds. Contributors from multiple academic and professional disciplines discuss how agricultural policies have contributed to current environmental conditions, and, in what the authors term 'alternative futures' for agricultural landscapes, envision how new policy can help achieve more beneficial patterns.

Models for Ecological Data

Models for Ecological Data PDF Author: James S. Clark
Publisher: Princeton University Press
ISBN: 0691220123
Category : Science
Languages : en
Pages : 634

Book Description
The environmental sciences are undergoing a revolution in the use of models and data. Facing ecological data sets of unprecedented size and complexity, environmental scientists are struggling to understand and exploit powerful new statistical tools for making sense of ecological processes. In Models for Ecological Data, James Clark introduces ecologists to these modern methods in modeling and computation. Assuming only basic courses in calculus and statistics, the text introduces readers to basic maximum likelihood and then works up to more advanced topics in Bayesian modeling and computation. Clark covers both classical statistical approaches and powerful new computational tools and describes how complexity can motivate a shift from classical to Bayesian methods. Through an available lab manual, the book introduces readers to the practical work of data modeling and computation in the language R. Based on a successful course at Duke University and National Science Foundation-funded institutes on hierarchical modeling, Models for Ecological Data will enable ecologists and other environmental scientists to develop useful models that make sense of ecological data. Consistent treatment from classical to modern Bayes Underlying distribution theory to algorithm development Many examples and applications Does not assume statistical background Extensive supporting appendixes Lab manual in R is available separately
