Book Description
Our Landscape Heritage provides an overview of the history and ecological makeup of the landscapes of New Brunswick to help ecological seekers starting out with basic knowledge about geology, soils, climate, and vegetation, to better understand why plants and animals are today distributed as they are. Part I outlines the rationale and history of ecological land classification (ELC) in New Brunswick, and presents basic scientific concepts and facts that help the reader to interpret the information that follows. Part II, Portrait of New Brunswick Ecoregions and Ecodistricts presents a detailed look at the variety and distribution of ecosystems across the geographic expanse of New Brunswick. Each of the seven chapters of Part II provides a high level description of the ecoregion, followed by detailed descriptions of each ecodistrict within the ecoregion.--Includes text from document.

Book Description
The general interest and attention paid to the use of the renewable natural resources of the world have increased greatly during the last decades. This is due to the environmental dilemma into which mankind has got itself by the total disregard of ecological facts and laws, the underprizing of natural resources and the overemphasis on economic develop ment, coupled with unimpeded rapid population growth and the preponderance of material istic consumption-oriented attitudes. The management and use of natural resources such as forests, grasslands, rivers and lakes were formerly considered purely in a financial context, whereas latterly, a consciousness of their social function and the indirect economic benefits which can be derived from them has developed. Thus, as regards these traditional resources, multi-use concepts comprising eco nomically oriented utilisation as well as recreational, educational and social use have be come widely accepted. Conservation of natural resources for sustainable consumptive as well as non-consumptive uses has been recognised as a key element for maintaining eco nomic development all over the world. Fortunately, the industrialised countries have started to apply this principle themselves and in their technical and financial aid to the developing Third World countries. This is manifest from policy documents such as the World Bank Policy on Development of Wild Lands, issued in 1987.

Book Description
Carrion, or dead animal matter, is an inherent component of aquatic and terrestrial ecosystems worldwide, and is exploited by a wide diversity of organisms from different trophic levels, including microbes, arthropods and vertebrates. Further, carrion consumption by scavengers, i.e. scavenging, supports key ecosystem functions and services such as recycling nutrients and energy, disposing of carcasses and regulating disease spread. Yet, unlike dead plant matter, dead animal decomposition has received little attention in the fields of ecology, wildlife conservation and environmental management, and as a result the management of carrion for maintaining biodiversity and functional ecosystems has been limited. This book addresses the main ecological patterns and processes relating to the generation and consumption of carrion both in terrestrial and aquatic ecosystems. It also discusses a number of conservation concerns and associated management issues, particularly regarding the increasing role of human-mediated carrion in ecosystems. Lastly, the book outlines future research lines in carrion ecology and management, and identifies the major challenges for scavengers and scavenging processes in the Anthropocene.

Book Description
The Himalaya, a global biodiversity hotspot, sustains about one-fifth of the humankind. Nestled within the north-western mountain ranges of the Himalaya, the Jammu and Kashmir (J&K) State harbours more than half of the biodiversity found in the Indian Himalaya. The wide expanse of State, spread across the subtropical Jammu, through the temperate Kashmir valley, to the cold arid Ladakh, is typical representative of the extensive elevational and topographical diversity encountered in the entire Himalaya. This book, the most comprehensive and updated synthesis ever made available on biodiversity of the J&K State, is a valuable addition to the biodiversity literature with global and regional relevance. The book, arranged into 7 parts, comprises of 42 chapters contributed by 87 researchers, each of whom is an expert in his/her own field of research. The precious baseline data contained in the book would form the foundation for assessing current status of knowledge about the bioresources, identify the knowledge gaps, and help prioritization of conservation strategies to steer the sustainable use of biodiversity in this Himalayan region. Given the breadth of topics covered under the banner of biodiversity in this book, it can surely serve as a model for documentation of biodiversity in other regions of the world. The book will be of immense value to all those who, directly or indirectly, have to deal with biodiversity, including students, teachers, researchers, naturalists, environmentalists, resource managers, planners, government agencies, NGOs and the general public at large.

Book Description
Remote photography and infrared sensors are widely used in the sampling of wildlife populations worldwide, especially for cryptic or elusive species. Guiding the practitioner through the entire process of using camera traps, this book is the first to compile state-of-the-art sampling techniques for the purpose of conducting high-quality science or effective management. Chapters on the evaluation of equipment, field sampling designs, and data analysis methods provide a coherent framework for making inferences about the abundance, species richness, and occupancy of sampled animals. The volume introduces new models that will revolutionize use of camera data to estimate population density, such as the newly developed spatial capture–recapture models. It also includes richly detailed case studies of camera trap work on some of the world’s most charismatic, elusive, and endangered wildlife species. Indispensible to wildlife conservationists, ecologists, biologists, and conservation agencies around the world, the text provides a thorough review of the subject as well as a forecast for the use of remote photography in natural resource conservation over the next few decades.

Book Description
Ecologists and natural resource managers are charged with making complex management decisions in the face of a rapidly changing environment resulting from climate change, energy development, urban sprawl, invasive species and globalization. Advances in Geographic Information System (GIS) technology, digitization, online data availability, historic legacy datasets, remote sensors and the ability to collect data on animal movements via satellite and GPS have given rise to large, highly complex datasets. These datasets could be utilized for making critical management decisions, but are often “messy” and difficult to interpret. Basic artificial intelligence algorithms (i.e., machine learning) are powerful tools that are shaping the world and must be taken advantage of in the life sciences. In ecology, machine learning algorithms are critical to helping resource managers synthesize information to better understand complex ecological systems. Machine Learning has a wide variety of powerful applications, with three general uses that are of particular interest to ecologists: (1) data exploration to gain system knowledge and generate new hypotheses, (2) predicting ecological patterns in space and time, and (3) pattern recognition for ecological sampling. Machine learning can be used to make predictive assessments even when relationships between variables are poorly understood. When traditional techniques fail to capture the relationship between variables, effective use of machine learning can unearth and capture previously unattainable insights into an ecosystem's complexity. Currently, many ecologists do not utilize machine learning as a part of the scientific process. This volume highlights how machine learning techniques can complement the traditional methodologies currently applied in this field.

Book Description
Global warming and human-driven impacts are changing the World’s ecological zones. This book applies the principles described in Bailey’s Ecosystem Geography: From Ecoregions to Sites, 2nd ed. (Springer 2009, 1st ed. 1996) to describe and characterize the major terrestrial and aquatic ecological zones of the Earth. Bailey’s system for classifying these zones has been adopted by major organizations such as the U.S. Forest Service and The Nature Conservancy and this book is a significant contribution to a long tradition of classifying and studying the world’s ecological regions or ecoregions. It includes two color maps that show the major ecoregions of the continents and oceans. Also included are: - 106 illustrations with 55 in full color - A new chapter on mountains is included. - There are new sections that address concerns about how eco regions are changing under the relentless influence of humans and climate change - Another new feature is the discussion of using eco regional patterns to transfer research results and select sites for detecting climate change effects on ecosystem distribution - Use of ecoregional patterns to design monitoring networks and sustainable landscapes - Fire regimes in different regional ecosystems and their management implications.
