Avian Urban Ecology (Hardcover): Diego Gil, Henrik Brumm Avian Urban Ecology (Hardcover)
Diego Gil, Henrik Brumm
R5,254 Discovery Miles 52 540 Ships in 12 - 19 working days

As natural habitat continues to be lost and the world steadily becomes more urbanized, biologists are increasingly studying the effect this has on wildlife. Birds are particularly good model systems since their life history, behaviour, and physiology are especially influenced by directly measurable environmental factors such as light and sound pollution. It is therefore relatively easy to compare urban individuals and populations with their rural counterparts. This accessible text focuses on the behavioural and physiological mechanisms which facilitate adaptation and on the evolutionary process that ensues. It discusses topics such as acoustics, reproductive cues, disease, and artificial feeding, and includes a series of case studies illustrating cutting edge research on these areas. Avian Urban Ecology is suitable for professional avian biologists and ornithologists as well as graduate students of avian ecology, evolution, and conservation. It will also be of relevance and use to a more general audience of urban ecologists and conservation biologists.

Coastal Water Bodies - Nature and Culture Conflicts in the Mediterranean (Hardcover, Edition.): Felicita Scapini, Gabriele... Coastal Water Bodies - Nature and Culture Conflicts in the Mediterranean (Hardcover, Edition.)
Felicita Scapini, Gabriele Ciampi
R3,026 Discovery Miles 30 260 Ships in 10 - 15 working days

Addressing the links between science and the real world with a sound scientific baseline, "Coastal Water Bodies" targets researchers of various disciplines whose interest lies in the integrated sustainable management of coastal water bodies. The main topic of this book is not the ecology according to its accepted meaning, but rather the places and people concerned the coastal zones of the Mediterranean that are rich in ecological value and the local people who survive thanks to these environmental resources.

Integration is the joint consideration of different aspects of water uses and values, and new ways of understanding and managing conflicts around water use are needed if people are to benefit from integration. Sustainability of the ecological and socioeconomic environments requires a climate in which conflicts, if they need to exist, are properly managed in a non-destructive manner.

R3,185 Discovery Miles 31 850 Ships in 10 - 15 working days

Wetlands are very sensitive ecosystems, functioning as habitat for many organisms. Protection and regeneration of wetlands are of great importance in ecological research and in nature conservation. A great amount of research has been done on the hydrology, plants and animals in wetlands. Knowledge on soil organisms and soil ecological processes of wetlands is still lacking. This knowledge is highly needed for landscape planning purposes or climate change predictions. For climate change, trace gas emissions from wetlands are of great interest. The authors provide an overview of state-of-the-art on soil ecology of wetlands. The book is divided in the following main chapters: "Wetlands as habitats for soil organisms", "Soil ecological processes in fens and floodplains", "Carbon and nitrogen dynamics in soils with different water regimes" and "Trace gas emissions".

Olav Giere
R5,975 Discovery Miles 59 750 Ships in 10 - 15 working days

Meiobenthology is the science of the tiny animals that live in huge numbers in all aquatic sediments. This fully revised and enlarged second edition emphasizes new discoveries and developments in this field. Major progress has been made in three general areas: - Systematics, diversity and distribution, - Ecology, food webs, and energy flow, - Environmental aspects, including studies of anthropogenic impacts.

The meiobenthos of polar and tropical regions, deep-sea bottoms and hydrothermal vents are now studied in more detail. The high number of species found to survive under such extreme conditions puts them at the forefront of biodiversity studies. Molecular screening methods enable large numbers to be analyzed upon applying reasonable effort. The aim of this book is to synthesize these modern scientific achievements such that meiobenthology can play a key role in aquatic research and in assessing the health of our environment.

Health in Ecological Perspectives in the Anthropocene (Hardcover, 1st ed. 2019): Toru Watanabe, Chiho Watanabe Health in Ecological Perspectives in the Anthropocene (Hardcover, 1st ed. 2019)
Toru Watanabe, Chiho Watanabe
R3,020 Discovery Miles 30 200 Ships in 10 - 15 working days

This book focuses on the emerging health issues due to climate change, particularly emphasizing the situation in developing countries. Thanks to recent development in the areas of remote sensing, GIS technology, and downscale modeling of climate, it has now become possible to depict and predict the relationship between environmental factors and health-related event data with a meaningful spatial and temporal scale. The chapters address new aspects of environment-health relationship relevant to this smaller scale analyses, including how considering people's mobility changes the exposure profile to certain environmental factors, how considering behavioral characteristics is important in predicting diarrhea risks after urban flood, and how small-scale land use patterns will affect the risk of infection by certain parasites, and subtle topography of the land profile. Through the combination of reviews and case studies, the reader would be able to learn how the issues of health and climate/social changes can be addressed using available technology and datasets. The post-2015 UN agenda has just put forward, and tremendous efforts have been started to develop and establish appropriate indicators to achieve the SDG goals. This book will also serve as a useful guide for creating such an indicator associated with health and planning, in line with the Ecohealth concept, the major tone of this book. With the increasing and pressing needs for adaptation to climate change, as well as societal change, this would be a very timely publication in this trans-disciplinary field.

An Integrated Assessment of China's Ecological Restoration Programs (Hardcover, 2009 ed.): Runsheng Yin An Integrated Assessment of China's Ecological Restoration Programs (Hardcover, 2009 ed.)
Runsheng Yin
R4,615 Discovery Miles 46 150 Ships in 10 - 15 working days

China has been undertaking unprecedented ecological restoration efforts to deal with its problems of soil erosion, flooding, dust storms, and habitat loss. While there have been studies of these efforts, questions remain concerning whether they have been effectively implemented, what their induced socioeconomic and ecological impacts are, and how their performance can be improved.

Tackling these important questions in an integrated manner, An Integrated Assessment of China 's Ecological Restoration Programs is extraordinary for its broad coverage and methodological rigor. It provides a substantial improvement over the conventional approach of simply reporting projects undertaken and accepting uncritically the government assessment, and thus fills an important knowledge gap of the restoration efforts being implemented upon a variety of ecosystems in China.

Moving Water - The Everglades and Big Sugar (Hardcover): Amy Green Moving Water - The Everglades and Big Sugar (Hardcover)
Amy Green
R658 Discovery Miles 6 580 Ships in 12 - 19 working days

A riveting story of environmental disaster and political intrigue, Moving Water exposes how Florida's clean water is threatened by dirty power players and the sugar cane industry. Only a century ago, nearly all of South Florida was under water. The Everglades, one of the largest wetlands in the world, was a watery arc extending over 3 million acres. Today, that wetland ecosystem is half of its former self, supplanted by housing for the region's exploding population and over 700,000 acres of crops, including the nation's largest supply of sugar cane. Countless canals, dams, and pump stations keep the trickle flowing, but rarely address the cascade of environmental consequences, including dangerous threats to a crucial drinking water source for a full third of Florida's residents. In Moving Water, environmental journalist Amy Green explores the story of unlikely conservation heroes George and Mary Barley, wealthy real estate developers and champions of the Everglades, whose complicated legacy spans from fisheries in Florida Bay to the political worlds of Tallahassee and Washington. At the center of their surprising saga is the establishment and evolution of the Comprehensive Everglades Restoration Plan (CERP), a $17 billion taxpayer-funded initiative aimed at reclaiming this vital ecosystem. Green explains that, like the meandering River of Grass, the progress of CERP rarely runs straight, especially when it comes up against the fierce efforts of sugar-growing interests, or "Big Sugar," to obstruct the cleanup of fertilizer runoff wreaking havoc with restoration. This engrossing expose tackles some of the most important issues of our time: Is it possible to save a complex ecosystem such as the Everglades-or, once degraded, are such ecological wonders gone forever? What kind of commitments-economic, scientific, and social-will it take to rescue our vulnerable natural resources? What influences do special interests wield in our everyday lives, and what does it take to push real reform through our democracy? A must-read for anyone fascinated by stories of political intrigue and the work of environmental crusaders like Erin Brockovich, as well as anyone who cares about the future of Florida, this book reveals why the Everglades serve as a model-and a warning-for environmental restoration efforts worldwide.

R5,159 Discovery Miles 51 590 Ships in 12 - 19 working days

The continuously growing human population along the world s coasts will exacerbate the impact of human activities on all coastal environments. Restoration activities will therefore become increasingly important. In particular, sandy shores and coastal dunes will require significant restoration efforts because they are preferred sites for human settlement, industrial and urban development and tourism.

With this book experts in the field present a comprehensive review of restoration studies and activities, where successful and failed studies or approaches from around the world are contrasted and compared. A major asset the book provides is a compendium of studies showing that coastal dune restoration has many definitions and thus leads to many different actions.

This volume addresses those with an interest in conservation ecology and biology, coastal dune dynamics and geomorphology, and coastal management who are seeking information on the different strategies for coastal dune restoration applied in different regions of the world. Finally, it will be a valuable resource for coastal scientists and planners, as well as for local and state officials, residents of coastal communities, environmental advocates and developers.

R4,769 Discovery Miles 47 690 Ships in 12 - 19 working days

Regional intercomparisons between ecosystems on different continents can be a powerful tool to better understand the ways in which ecosystems respond to global change. Large areas are often needed to characterize the causal mechanisms governing interactions between ecozones and their environments. Factors such as weather and climate patterns, land-ocean and land-atmosphere interactions all play important roles. As a result of the strong physical north-south symmetry between the western coasts of North and South America, the similarities in climate, coastal oceanography and physiography between these two regions have been extensively documented. High Latitude Rain Forests and Associated Ecosystems of the West Coast of the Americas presents current research on West Coast forest and river ecology, and compares ecosystems of the Pacific Northwest with those of South America.

R2,089 Discovery Miles 20 890 Ships in 12 - 19 working days

This book presents the results from the Japanese Fisheries Research Agency's 3-year intensive monitoring of radionuclides in a variety of fish, plankton, benthos, and their living environments after the Fukushima Daiichi Nuclear Power Plant (FNPP) accident in March 2011. The book reveals the dynamics of contamination processes in marine and freshwater fish, mediated by the contamination of water, sediments, and food organisms; it also clarifies the mechanisms by which large variations in the level of contamination occurs among individual fish. Most importantly, the book includes a large amount of original measurement data collected in situ and for the first time assesses diffusion of radiocesium across the Pacific using both in situ data and a numerical simulation model. Also introduced are several new approaches to evaluate the impact of the release of radionuclides, including the measurement of radiation emission from an otolith section to identify the main period of contamination in fish. The FNPP accident represents a rare instance where the environmental radioactivity level was elevated steeply through atmospheric fallout and direct discharge of radioactive water into the sea over a short period of time. Replete with precise scientific data, this book will serve as an important resource for research in fields such as fishery science, oceanography, ecology, and environmentology, and also as a solid basis for protecting fisheries from damage resulting from harmful rumors among the general public.

R5,060 Discovery Miles 50 600 Ships in 12 - 19 working days

Stable isotope ratio variation in natural systems reflects the dynamics of Earth systems processes and imparts isotope labels to Earth materials. Carbon isotope ratios of atmospheric CO2 record exchange of carbon between the biosphere and the atmosphere; the incredible journeys of migrating monarchs is documented by hydrogen isotopes in their wings; and water carries an isotopic record of its source and history as it traverses the atmosphere and land surface. Through these and many other examples, improved understanding of spatio-temporal isotopic variation in Earth systems is leading to innovative new approaches to scientific problem-solving. This volume provides a comprehensive overview of the theory, methods, and applications that are enabling new disciplinary and cross-disciplinary advances through the study of "isoscapes": isotopic landscapes.

"This impressive new volume shows scientists deciphering and using the natural isotope landscapes that subtly adorn our spaceship Earth.," Brian Fry, Coastal Ecology Institute, Louisiana State University, USA

"An excellent timely must read and must-have reference book for anybody interested or engaged in applying stable isotope signatures to questions in e.g. Anthropology, Biogeochemistry, Ecology, or Forensic Science regarding chronological and spatial movement, changes, or distribution relating to animals, humans, plants, or water.," Wolfram Meier-Augenstein, Centre for Anatomy & Human Identification, University of Dundee, UK

"Natural resources are being affected by global change, but exactly where, how, and at what pace? Isoscapes provide new and remarkably precise answers.," John Hayes, Woods Hole Oceanographic Institution, USA

"This exciting volume is shaping a new landscape in environmental sciences that is utilizing the remarkable advances in isotope research to enhance and extend the capabilities of the field.," Dan Yakir, Weizmann Institute of Science, Israel

J. Kostkowska
R4,907 Discovery Miles 49 070 Ships in 12 - 19 working days

Virginia Woolf, Jeanette Winterson, and Ali Smith share an ecological philosophy of the world as one highly interconnected entity comprised of multiple and equal, human and non-human participants. This study argues that these writers' ecocentric views find expression through their literary forms and that their texts have an ecological significance in fostering respect for and understanding of difference, human and nonhuman. Beginning with Woolf's work, these writers abandon the hegemonic master narrative and instead practice pluralistic, democratic, and non-authoritarian forms that are consistent with feminist ecology and erode patriarchal domination. Their texts have a world-transforming potential as they offer formal models that overcome dualistic thinking and unsettle traditional binaries. The value transformation they encourage is an indispensible groundwork for the new environmental philosophy and a prerequisite to progressive action and change.

Mahua Mukherjee, Rajib Shaw
R4,706 Discovery Miles 47 060 Ships in 12 - 19 working days

This book provides an introduction to the critical role of ecosystem-based disaster risk resilience (Eco-DRR) for building community resilience to multiple environmental risks such as rising heat, water stress, and pollution. Blue-green infrastructure (BGI) is an Eco-DRR tool that is an under-explored paradigm and can respond as one common strategy to targets set by the Sustainable Development Goals (UNDP), Climate Agreements (UNEP), the Sendai Framework (UNISDR), and the New Urban Agenda (UNCHS). Highlighted here in a systematic way is the importance of blue-green infrastructures in resilience building. The purpose is to introduce readers to the challenging context of development and opportunity creation for Eco-DRR. The roles of policy, scientific research, and implementation are presented cohesively. An attractive proposition of the book is a collection of case studies from different parts of the world where integration of BGI is experimented with at various levels of success. It envisages that shared tacit experiences from the realm of practice will further strengthen explicit knowledge. The focus in this book is on need and context building, policy and science (investigation, analysis, and design), case studies, and a road map for the future in four successive parts. Each part is self-sufficient yet linked to its predecessor, successor, or both, as the case may be.

Emma Orive, M. Elliott, Victor N. de Jonge
R6,067 Discovery Miles 60 670 Ships in 10 - 15 working days

This volume focuses on the nutrient and organic matter inputs in estuaries and other coastal ecosystems, their effects on geochemistry and community structure and possibilities for recovery of the systems to a trophic state that is beneficial for man and nature.
The book provides many examples of the effects of the enhanced supply of nutrients and organic matter on the chemical features of the water and on the structure, metabolism and trophic pathways of the biological communities.
Also included are several case studies providing considerable insight into the response of the different coastal ecosystems to long term changes in the trophic state of the water.
Current knowledge on modeling as a tool to manage the trophic state of the coastal ecosystems is also dealt with, making this book one of interests to scientist and students as well as managers.

Jens Lachmund, Raf De Bont
R5,029 Discovery Miles 50 290 Ships in 12 - 19 working days

Throughout its history, the discipline of ecology has always been profoundly entangled with the history of space and place. On the one hand, ecology is a field science that has thrived on the study of concrete spatial entities, such as islands, forests or rivers. These spaces are the workplaces in which ecological phenomena are identified, observed and experimented on. They provide both epistemic opportunities and constraints that structure the agenda and the analytical sensibilities of ecological researchers. On the other hand, ecological knowledge and practices have become important resources through which spaces and places are classified, delineated, explained, experienced and managed. The impact of these activities reaches far beyond the realms of the ecological discipline. Many ecological concepts such as "biotopes," "ecosystems" and "the biosphere" have become entities that widely resonate in public life and policy making. This book explores the mutual entanglement between space and knowledge-making in the history of ecology. Its first goal is to explore to which extent a spatial perspective can shed new light on the history of ecological science. Second, it uses ecology as a critical site to gain broader insights into the history of the environment in the nineteenth and twentieth centuries. Via a series of case studies - discussing topics that range from ecological field stations in the early-twentieth century Caribbean over wisent breeding in Nazi Germany to computer modelling in North American deserts - the book offers a tour through the changing landscapes of modern ecology.

R5,949 Discovery Miles 59 490 Ships in 10 - 15 working days

This book is an attempt to compile and integrate the information documented by many botanists, both Egyptians and others, about the vegetation of Egypt. The ? rst treatise on the ? ora of Egypt, by Petrus Forsskal, was published in 1775. Records of the Egyptian ? ora made during the Napoleonic expedition to Egypt (1778-1801) were provided by A. R. Delile from 1809 to 1812 (Kassas, 1981). The early beginning of ecological studies of the vegetation of Egypt extended to the mid-nineteenth century. Two traditions may be recognized. The ? rst was general exploration and survey, for which one name is symbolic: Georges-Auguste Schweinfurth (1836-1925), a German scientist and explorer who lived in Egypt from 1863 to 1914. The second tradition was ecophysiological to explain the plant life in the dry desert. The work of G. Volkens (1887) remains a classic on xeroph- ism. These two traditions were maintained and expanded in further phases of e- logical development associated with the establishment of the Egyptian University in 1925 (now the University of Cairo). The ? rst professor of botany was the Swedish Gunnar Tackholm (1925-1929). He died young, and his wife Vivi Tackholm devoted her life to studying the ? ora of Egypt and gave leadership and inspiration to plant taxonomists and plant ecologists in Egypt for some 50 years. She died in 1978. The second professor of botany in Egypt was F. W.
