Australia's varied grasslands have suffered massive losses and changes since European settlement, and those changes continue under increasingly intensive human pressures for development and agricultural production. The values of native grasslands for conservation of endemic native biodiversity, both flora and fauna, have led to strong interests in the protection of remaining fragments, especially near urban centres, and documentation of the insects and other inhabitants of grasslands spanning tropical to cool temperate parts of the country. Attention to conservation of grassland insects in Australia is relatively recent, but it is increasingly apparent that grasslands harbour many localised and ecologically specialised endemic species. Their conservation necessarily advances from very incomplete documentation, and draws heavily on lessons from the far better-documented grasslands elsewhere, most notably in the northern hemisphere, and undertaken over far longer periods. From those cases, and the extensive background to grassland management to harmonise conservation with production and amenity values through honing use of processes such as grazing, mowing and fire, the needs and priorities for Australia can become clearer, together with needs for grassland restoration at a variety of scales. This book is a broad overview of conservation needs of grassland insects in Australia, drawing on the background provided elsewhere in the world on the responses to disturbances, and the ecological importance, of some key insect groups (notably Orthoptera, Hemiptera and Lepidoptera) to suggest how insect conservation in native, pastoral and urban grasslands may be advanced. The substantial references given for each chapter facilitate entry for non-entomologist grassland managers and stewards to appreciate the diversity and importance of Australia's grassland insects, their vulnerabilities to changes, and the possibilities for conserving them and the wider ecological roles in which they participate.
Professor Linda M. Fedigan, Member of the Order of Canada and a Fellow of the Royal Society of Canada, has made major contributions to our understanding of the behavioural ecology of primates. Furthermore, Linda Fedigan pioneered and continues to advance scholarship on the role of women in science, as well as actively promoting the inclusion of women in the academy. A symposium in honour of her career was held in Banff (Alberta, Canada) in December 2016, during which former and current students and collaborators, as well as scientists with similar research interests, presented and discussed their work and their connections to Linda Fedigan. These presentations and discussions are here presented as chapters in this festschrift. The original works presented in this book are organized around four major research areas that have been greatly advanced and influenced by Linda Fedigan: Primate life histories Sex roles, gender, and science Primate-environment interactions Primate adaptation to changing environments
Butterflies and moths hold an enduring fascination for their unusual life cycle, as they change from one creature into another. Butterflies is an outstanding collection of photographs showcasing nature's most beautiful and often elusive butterflies and moths - members of the Lepidoptera order - in the variety of their natural habitats. With 17,500 species of butterfly and 160,000 species of moth in the world today, they can be found on every continent apart from Antarctica, and in every nation. Arranged in chapters covering some of the most beautiful and interesting types of butterfly and moth, their habitats, their transition from egg to caterpillar and from chrysalid to adult, as well as their behaviour, the book reveals little-known facts about their life cycle, anatomy, self-defence mechanisms, feeding and migration. For example, did you know that while caterpillars chew their solid food, adult butterflies can only consume liquid, and some moths do not even have mouths? Or that many species can taste with their feet? With full captions explaining how the species breeds, feeds, and changes from caterpillar to the animal kingdom's most stunning member, Butterflies is a brilliant examination in more than 200 outstanding colour photographs of these fascinating insects.
The lake charr Salvelinus namaycush is a ubiquitous member of cold-water lake ecosystems in previously glaciated regions of northern continental U.S., Alaska, and Canada that often support important commercial, recreational, and subsistence fisheries. The lake charr differs from other charrs by its large size, longevity, iteroparity, top-predator specialization, reduced sexual dimorphism, prevalence of lacustrine spawning, and use of deepwater habitat. The species is remarkably variable in phenotype, physiology, and life history, some of which is reflected in its ecology and genetics, with as many as four morphs or ecotypes co-occurring in a single lake. The lake charr is often the top predator in these systems, but is highly adaptable trophically, and is frequently planktivorous in small lakes. The lake charr by their name highlights their common habitat, lakes both large and small, but often frequents rivers and occasionally moves into the Arctic Ocean. Movement and behaviour of lake charr are motivated by access to cool, well-oxygenated water, foraging opportunities, predator avoidance, and reproduction. Owing to their broad distribution and trophic level, the lake charr serves as a sentinel of anthropogenic change. This volume will provide an up-to-date summary of what is currently known about lake charr from distribution to genetics to physiology to ecology. The book provides a compilation and synthesis of available information on the lake charr, beginning with an updated distribution and a revised treatment of the paleoecology of the species. Understanding of ecological and genetic diversity and movement and behaviour of the species has advanced remarkably since the last major synthesis on the species over 40 years ago. Mid-sections of the book provide detailed accounts of the biology and life history of the species, and later sections are devoted to threats to conservation and fishery management practices used to ensure sustainability. A new standard lake charr-specific terminology is also presented. The book will be a valuable reference text for biologists around the world, ecologists, and fishery managers, and of interest to the angling public.
From the Texas Blackland Prairies to the Middle Atlantic Coastal Plain of the Carolinas, this volume provides a snapshot of the most spectacular and important natural places in the southern United States. America's Natural Places: South and Southeast examines over 50 of the most spectacular and important areas of this region, with each entry describing the importance of the area, the flora and fauna that it supports, threats to the survival of the region, and what is being done to protect it. Organized by state within the volume, this book informs readers about the wide variety of natural areas across the south and southeast and identifies places near them that demonstrate the importance of preserving such regions.
Cheetahs: Biology and Conservation reports on the science and conservation of the cheetah. This volume demonstrates the interdisciplinary nature of research and conservation efforts to study and protect the cheetah. The book begins with chapters on the evolution, genetics, physiology, ecology and behavior of the species, as well as distribution reports from range countries. These introductory chapters lead into discussions of the challenges facing cheetah survival, including habitat loss, declining prey base, human-wildlife conflict, illegal trade, and newly-emerging threats, notably climate change. This book also focuses on conservation strategies and solutions, including environmental education and alternative livelihoods. Chapters on the role of captive cheetahs to conservation and the long-term research of the species are included, as are a brief discussion of the methods and analyses used to study the cheetah. The book concludes with the conservation status and future outlook of the species. Cheetahs: Biology and Conservation is a valuable resource for the regional and global communities of cheetah conservationists, researchers, and academics. Although cheetah focussed the book provides information relevant to the study of broader topics such as wildlife conservation, captive breeding, habitat management, conservation biology and animal behaviour.

Nearshore hardbottom reefs of Florida's east coast are used by over 1100 species of fishes, invertebrates, algae, and sea turtles. These rocky reefs support reproduction, settlement, and habitat use, and are energy sources and sinks. They are also buried by beach renourishment projects in which artificial reefs are used for mitigation. This comprehensive book is for research scientists and agency personnel, yet accessible to interested laypersons including beachfront residents and water-users. An unprecedented collection of research information and often stunning color photographs are assembled including over 1250 technical citations and 127 figures. These shallow reefs are part of a mosaic of coastal shelf habitats including estuarine seagrasses and mangroves, and offshore coral reefs. These hardbottom habitats are federally designated as Essential Fish Habitats - Habitats of Particular Concern and are important feeding areas for federally-protected sea turtles. Organismal and assemblage responses to natural and man-made disturbances, including climate change, are examined in the context of new research and management opportunities for east Florida's islands in the sand.
"The Game of Conservation" is a brilliantly crafted and highly
readable examination of nature protection around the world.
Habitat management is commonly used to maintain and enhance the
biological interest of many areas of semi-natural habitat where
natural processes no longer create suitable conditions for desired
species. Habitat restoration and creation is increasingly being
used to increase the extent of ecologically important habitats in
order to mitigate the impacts of human development. The
modification of past management techniques and the introduction of
new ones can provide additional benefits.
This book encompasses the body of available scientific information on the notothenioid fish Pleuragramma antarctica commonly known as Antarctic silverfish. This plankton-feeder of the intermediate trophic level is the most abundant fish in the coastal regions of high Antarctica, and plays a pivotal ecological role as the main prey of top predators like seals, penguins, whales and Antarctic toothfish. Broad circum-polar distribution, a key role in the Antarctic shelf pelagic ecosystem, and adaptations makes understanding the species' likely response to environmental change relevant to foresee the potential responses at the local ecosystem level. Additionally, a detailed understanding of the abundance and trophic interactions of such a dominant keystone species is a vital element of informing the development of marine spatial planning and marine protected areas in the Antarctic continental shelf region. Experts in the field provide here unique insights into the evolutionary adaptation, eco-physiology, trophic ecology, reproductive and population ecology of the Antarctic silverfish and provide new clues about its vulnerability in facing the challenges of the ongoing environmental changes.
Austere and immense, the Arctic region is a fascinating topic for
intrepid travelers and stay at home students alike. This new guide
in the Pocket Naturalist series covers the variety of flora and
fauna that have adapted to this incredible, remote environment with
trademark beauty and accuracy.
Winner of the Marsh Book of the Year Award (2015) Throughout British history rivers have been of profound economic, social and cultural importance - yet as we see with increasing frequency they have the potential to wreak great destruction. This book describes the natural and not-so-natural changes that have affected British rivers since the last ice age and looks at the many plants and animals that live along, above and within them. Detailed case studies of the Meon, Dee and Endrick illustrate the incredibly varied nature of our river ecosystems, and the natural and human factors that make each one different. Written by two widely respected river ecologists, the book looks not only at rivers as they were and are but also at how they can be managed and cared for. Full of interesting facts and stunning images, Rivers is essential reading for anyone professionally involved in rivers and for the naturalist, conservationist and layman alike. It is the one book you need to understand this singularly important and often contentious feature of the British landscape.
Meso and Microplastic Risk Assessment in Marine Environment: New Threat and Challenges in Marine Environment presents an interdisciplinary approach, offering key techniques and management of microplastic contamination in the disciplines of environmental science, fisheries, oceanography, geology, chemistry, biology and ocean science. Sections cover an overview of microplastic in the marine environment, deal with the origin, occurrences, distribution and various methodologies (for dealing with microplastics) available for microplastics, address the global case study of microplastic separation using recent techniques, and discuss the impact of microplastics on human health and the surrounding environment. This book is an important step in the field of microplastic pollution mitigation in environmental science as it offers a thorough accounting of the effects of pollutants on the environment, marine organisms, and the public health implications, as such it is relevant for aquatic ecologists, oceanographers, toxicologists, and marine biologists.
This book summarizes current advances in our understanding of how infectious disease represents an ecological interaction between a pathogenic microorganism and the host species in which that microbe causes illness. The contributing authors explain that pathogenic microorganisms often also have broader ecological connections, which can include a natural environmental presence; possible transmission by vehicles such as air, water, and food; and interactions with other host species, including vectors for which the microbe either may or may not be pathogenic. This field of science has been dubbed disease ecology, and the chapters that examine it have been grouped into three sections. The first section introduces both the role of biological community interactions and the impact of biodiversity on infectious disease. In turn, the second section considers those diseases directly affecting humans, with a focus on waterborne and foodborne illnesses, while also examining the critical aspect of microbial biofilms. Lastly, the third section presents the ecology of infectious diseases from the perspective of their impact on mammalian livestock and wildlife as well as on humans. Given its breadth of coverage, the volume offers a valuable resource for microbial ecologists and biomedical scientists alike.
This book explores how NGOs have been influential in shaping global biodiversity, conservation policy, and practice. It encapsulates a growing body of literature that has questioned the mandates, roles, and effectiveness of these organizations-and the critique of these critics. This volume seeks to nurture an open conversation about contemporary NGO practices through analysis and engagement.
Veld is a natural resource vital to our survival on earth. About 80% of our beautiful country consists of veld. Most of this area is used for livestock and game ranching as well as for biodiversity conservation and recreation. Good veld management is needed to prevent land degradation and to ensure sustainable food production and biodiversity conservation. But good veld management relies on a good knowledge of ecological principles and veld management practices, something many land users did not have the privilege to acquire. This book aims to provide the necessary knowledge to assist land users to effectively manage the land under their care, a huge responsibility indeed.
A burning mix of diesel fuel and gasoline drips from handheld canisters onto the ground. Slowly a line of fire begins to creep downhill. The flames are well behaved, almost hesitant. This is a backing fire, unlikely to attract media attention unless it escapes, like the disastrous Los Alamos Cerro Grande fire did in 2000. This book explores a century of controversy over prescribed burning--using fire as a tool--and fire suppression. For more than 100 years, America waged an all-out war against wildland fire. Decades of fire suppression caused fuels to build up at alarming levels in our forests, culminating in the increasingly severe, uncontrollable fires of the late 20th century--the fires in Yellowstone, the Oakland Hills, and Los Alamos and the fires in summers of 2000 (the second worst fire season in the nation's history) and 2001. Looking at these and earlier fires, Carle uses the voices of those who were involved, of those who were early advocates, and of today's proponents to examine the role of controlled burning. Early in the century, Harold Biswell, a pioneer in prescribed burning, dared to commit the heresy of questioning the dogma of fire suppression, despite professional controversy and opprobrium, he and a few other pioneers led the way. Their roles play an integral part in the story told here. In Biswell's words, fire is a natural part of the environment, about as important as rain and sunshine... . We must work more in harmony with nature, not so much against it. Can humanity, this book asks, learn to become a fire-adapted species?
In the endless light of summer days, and the magical gloaming of the wee small hours, nature in Jim's beloved Highlands, Perthshire and Trossachs heartlands is burgeoning freely, as though there is one long midsummer's eve, nothing reserved. For our flora and fauna, for the very land itself, this is the time of extravagant growth, flowering and the promise of fruit and the harvest to come. But despite the abundance, as Jim Crumley attests, summer in the Northlands is no Wordsworthian idyll. Climate chaos and its attendant unpredictable weather brings high drama to the lives of the animals and birds he observes. There is also a wild, elemental beauty to the land, mountains, lochs, coasts and skies, a sense of nature at its very apex during this, the most beautiful and lush of seasons. Jim chronicles it all: the wonder, the tumult, the spectacle of summer - and what is at stake as our seasons are pushed beyond nature's limits.
