Download or read book Predictive Species and Habitat Modeling in Landscape Ecology written by C. Ashton Drew and published by Springer Science & Business Media. This book was released on 2010-11-25 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most projects in Landscape Ecology, at some point, define a species-habitat association. These models are inherently spatial, dealing with landscapes and their configurations. Whether coding behavioral rules for dispersal of simulated organisms through simulated landscapes, or designing the sampling extent of field surveys and experiments in real landscapes, landscape ecologists must make assumptions about how organisms experience and utilize the landscape. These convenient working postulates allow modelers to project the model in time and space, yet rarely are they explicitly considered. The early years of landscape ecology necessarily focused on the evolution of effective data sources, metrics, and statistical approaches that could truly capture the spatial and temporal patterns and processes of interest. Now that these tools are well established, we reflect on the ecological theories that underpin the assumptions commonly made during species distribution modeling and mapping. This is crucial for applying models to questions of global sustainability. Due to the inherent use of GIS for much of this kind of research, and as several authors’ research involves the production of multicolored map figures, there would be an 8-page color insert. Additional color figures could be made available through a digital archive, or by cost contributions of the chapter authors. Where applicable, would be relevant chapters’ GIS data and model code available through a digital archive. The practice of data and code sharing is becoming standard in GIS studies, is an inherent method of this book, and will serve to add additional research value to the book for both academic and practitioner audiences.

Download or read book The Butterflies of Canada written by Ross Layberry and published by University of Toronto Press. This book was released on 1998-12-15 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beautifully illustrated and clearly presented, The Butterflies of Canada is an indispensable guide to all aspects of butterfly study. Butterfly collecting has long been a popular summer activity, and as the growing popularity of butterfly watching and conservatories in Ontario and British Columbia shows, butterflies are a continuing source of delight and interest to Canadians. The Butterflies of Canada is the first comprehensive guide to all the butterflies found in Canada. Based on the national butterfly collection maintained by Agriculture and Agri-Food Canada, it contains descriptive individual accounts for the close to three hundred butterfly species recorded in Canada, including descriptions of early stages, subspecies, and key features that help distinguish similar species. Each species of butterfly has an individual distribution map, generated from a database of more than 90,000 location records. More than just a field guide to identifying Canadian butterflies, however, The Butterflies of Canada includes chapters on Canadian geography and butterfly distribution, conservation, gardening, photography, and the history of butterfly study in Canada. It also contains new and unpublished information on the classification of butterflies, their ranges, larval food plants, abundance, flight seasons, and noteworthy habits. Thirty two colour plates provide diagnostic details for each species, and also feature butterflies in their natural habitats. There is an extensive bibliography.

Download or read book Accidental Wilderness written by Walter H. Kehm and published by University of Toronto Press. This book was released on 2020-11-30 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fortuitous urban miracle, Tommy Thompson Park is an oasis of "accidental wilderness" on Toronto’s lakeshore. Initially created as a landfill site on the city’s rapidly developing waterfront, the Leslie Street Spit, as the park is affectionately known, has seen its physical and ecological footprint grow dramatically over recent decades. Forests, grasslands, and wildlife now thrive – all within a stone’s throw of some of the most densely populated areas of North America’s fourth-largest city/ Accidental Wilderness is a rich and lyrical collection of essays curated by internationally recognized landscape architect and original designer of Tommy Thompson Park, Walter H. Kehm. A stunning collection of photographs by renowned landscape photographer Robert Burley complements these essays, which explore the city’s port origins; the principles and design of the park’s master plan; the native-plant succession process; the park’s unique flora and fauna; public advocacy efforts; and public recreation in the park and its effect on mental, physical, and spiritual health. In an era when the dangers of climate change have begun to affect daily life, Tommy Thompson Park offers a hopeful narrative about how nature can flourish in, and contribute to, the well-being of twenty-first-century cities.

Book excerpt: "Highly compelling...page-turning read" — TNC's Cool Green Science We love our pets. Dogs, cats, birds, reptiles, and other species have become an essential part of more families than ever before—in North America today, pets outnumber people. Pet owners are drawn to their animal companions through an innate desire to connect with other species. But there is a dark side to our domestic connection with animal life: the pet industry is contributing to a global conservation crisis for wildlife—often without the knowledge of pet owners. In Unnatural Companions, journalist Peter Christie issues a call to action for pet owners. If we hope to reverse the alarming trend of wildlife decline, pet owners must acknowledge the pets-versus-conservation dilemma and concede that our well-fed and sheltered cats too often prey on small backyard wildlife and seemingly harmless reptiles released into the wild might be the next destructive invasive species. We want our pets to eat nutritionally healthy food, but how does the designer food we feed them impact the environment? Christie's book is a cautionary tale to responsible pet owners about why we must change the ways we love and care for our pets. It concludes with the positive message that the small changes we make at home can foster better practices within the pet industry that will ultimately benefit our pets’ wild brethren.

Available in PDF, EPUB and Kindle. Book excerpt: Winner of the IENE Project Award 2016. This authoritative volume brings together some of the world’s leading researchers, academics, practitioners and transportation agency personnel to present the current status of the ecological sustainability of the linear infrastructure – primarily road, rail and utility easements – that dissect and fragment landscapes globally. It outlines the potential impacts, demonstrates how this infrastructure is being improved, and how broad ecological principles are applied to mitigate the impact of road networks on wildlife. Research and monitoring is an important aspect of road ecology, encompassing all phases of a transportation project. This book covers research and monitoring to span the entire project continuum – starting with planning and design, through construction and into maintenance and management. It focuses on impacts and solutions for species groups and specific regions, with particular emphasis on the unique challenges facing Asia, South America and Africa. Other key features: Contributions from authors originating from over 25 countries, including from all continents Each chapter summarizes important lessons, and includes lists of further reading and thoroughly up to date references Highlights principles that address key points relevant to all phases in all road projects Explains best-practices based on a number of successful international case studies Chapters are "stand-alone", but they also build upon and complement each other; extensive cross-referencing directs the reader to relevant material elsewhere in the book Handbook of Road Ecology offers a comprehensive summary of approximately 30 years of global efforts to quantify the impacts of roads and traffic and implement effective mitigation. As such, it is essential reading for those involved in the planning, design, assessment and construction of new roads; the management and maintenance of existing roads; and the modifying or retrofitting of existing roads and problem locations. This handbook is an accessible resource for both developed and developing countries, including government transportation agencies, Government environmental/conservation agencies, NGOs, and road funding and donor organisations.
