Nowadays, habitat loss is one of the main threats to terrestrial vertebrates' survival. Due to the decreasing of continuous natural areas, and consequent habitat loss, how animals use these remaining patches, is becoming a central question for the conservation of these species. The loss of the original land covers can promote a change in the composition, diversity and behaviour of the native fauna, as well as constrain the community structures. The outcome of these processes of habitat fragmentation due to human agro-forestry management is a landscape where patches of autochthonous/native vegetation are immersed in a matrix of human shaped landscapes. Although some carnivores are sensitive to fragmentation, some species can benefit with the expansion of agriculture. This book discusses the importance and role of those agricultural matrix for species conservation.

The state of São Paulo, Brazil, is one of the most densely populated and developed areas in South America. Such development is evident both in terms of industrialization and urbanization, as well as in agriculture, which is heavily based on sugar cane, Eucalyptus plantations and livestock. This intense land use has resulted in great alteration of the original land cover and fragmentation of natural ecosystems. For these reasons, it is almost a paradox that jaguar, a species that requires large areas of pristine forest to exist, is still found in some parts of the state of São Paulo. It is possible that wild animals could leave in coexistence with intense land use, or is it the case that such rare encounters with large wild animals in São Paulo will disappear in the near future? All ecologists are aware of the problems of habitat changes caused by humans, but it was not until recent years that researchers started to consider that the land used for production could also serve as an important habitat for many different kinds of wild species. This book is about this new approach to conservation. It also highlights the important role that sciences could and should have in this discussion in order to better understand the problems and propose possible solutions.

This book provides both the conceptual basis and technological tools that are necessary to identify and solve problems related to biodiversity governance. The authors discuss intriguing evolutionary questions, which involve the sometimes surprising adaptive capacity of certain organisms to dwell in altered and/or changing environments that apparently lost most of their structure and functionality. Space and time heterogeneities are considered in order to understand the patterns of distribution and abundance of species and the various processes that mold them. The book also discusses at which level—from genes to the landscape, including individuals, populations, communities, and ecosystems—men should intervene in nature in order to prevent the loss of biodiversity.

Habitat loss and fragmentation arguably pose the greatest threats to biological diversity. Agriculture is a dominant land use that, along with urban sprawl and residential development, can reduce the amount and connectedness of natural areas required by many native species. Unfortunately, progress has been slow in integrating nature and biodiversity protection into community planning in intensively farmed regions, especially in America's heartland. Seldom do issues related to species conservation receive consideration during local planning activities. Lack of progress stems partly from scientific inadequacies in understanding the dynamics of complex landscapes, and from a lack of engagement of non-scientific stakeholders by scientists and modelers. The result of these shortcomings is a critical disconnect of conservation issues from the planning infrastructure. This book provides a blueprint for advancing conceptual understanding of conservation in agricultural regions. It accomplishes this with a two-pronged approach: first, by developing spatially structured models that acknowledge the link between socio-economic drivers of land-use change and the dynamics of species occupying agricultural landscapes with abrupt changes in land cover (i.e., sharp edges); and second, by providing guidelines and examples to enable scientists to effectively engage stakeholders in participatory learning and planning activities that integrate biodiversity with other, more traditional, considerations. The structure of the book is truly interdisciplinary, linking the efforts of ecologists, economists, statisticians, mathematicians, and land-use specialists.

The Tasmanian devil is threatened by Devil Facial Tumour Disease (DFTD), a transmissible form of cancer that has reduced the population by over 80%. Persecution, extreme climate events, vehicle collision and habitat destruction also put pressure on this endangered species. The recovery effort to save the Tasmanian devil commenced over 15 years ago as a collaborative initiative between the Tasmanian government, the Australian government, the Zoo and Aquarium Association Australasia, and many research institutions. Saving the Tasmanian Devil documents the journey taken by partner organisations in discovering what DFTD is, the effect it has on wild devil populations, and the outcomes achieved through research and management actions. Chapters describe all aspects of devil conservation, including the captive devil populations, applied pathology, immunology and genetic research findings, adaptive management, and the importance of advocacy and partnerships. This book will provide management practitioners and conservation scientists with insight into the complexities of undertaking a program of this scale, and will also be of value to researchers, students and others interested in conservation.

The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.

Thorough, detailed, and scientifically up-to-date, Prairies: A Natural History provides a comprehensive nontechnical guide to the biology and ecology of the prairies, or the Great Plains grasslands of North America, offering a view of the past, a vision for the future, and a clear focus on the present. With a total area of more than 3.5 million square kilometers (500,000 in Canada and the remainder in the United States), the prairies occupy the heartland of the continent, a vast, windswept plain that flows from Alberta south to Texas and from the Rockies east to the Mississippi River. This is big sky country—the largest ecosystem in North America and, until recently, one of the richest and most magnificent natural grasslands in the world. Today, however, the North American prairies are among the most altered environments on Earth.
