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.
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.
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.
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.
"The Game of Conservation" is a brilliantly crafted and highly
readable examination of nature protection around the world.
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.
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.
Fish and shellfish comprise annually nearly 70-million tons of the
world's edible animal protein. However, because of this demand,
previously vast stocks have often been exhausted to the point of
near extinction. The first book of its kind in the area of
freshwater/marine biodiversity, this extensive work reviews the
present status of genetic resource management, its needs and
constraints, various intervening human factors such as pollution
and overfishing, and problems posed by different species and
life-styles. This discussion of the conservation of fish and
shellfish resources is illustrated by four diverse groups: Atlantic
salmon, cupped oysters, common and Chinese carp, and Nile tilapia.
These results, produced by the collaboration of nine leading
population and production geneticists, aquaculturists, and
behavioral and developmental ecologists should become a fundamental
resource useful to biologists, scientists and advisors exploring
current issues in the fishery sciences.
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.
Spring is nature's season of rebirth and rejuvenation. Earth's northern hemisphere tilts towards the sun, winter yields to intensifying light and warmth, and a wild, elemental beauty transforms the Highland landscape and a repertoire of islands from Colonsay to Lindisfarne. Jim Crumley chronicles the wonder, tumult and spectacle of that transformation, but he shows too that it is no Wordsworthian idyll that unfolds. Climate chaos brings unwanted drama to the lives of badger and fox, seal and seabird and raptor, pine marten and sand martin. Jim lays bare the impact of global warming and urges us all towards a more daring conservation vision that embraces everything from the mountain treeline to a second spring for the wolf.

The latest innovations are also included to provide insights into the unlimited potentials of microorganisms in these areas.Individual chapters explore topics such as probiotics in poultry, biopurification of wastewater, converting agrowastes into value-added applications and products, rice cultivation, surfactants and bacteriocin as biopreservatives, bioplastics, crop productivity, biofloc, and the production of natural antibiotics. This volume will be of particular interest to scientists, policymakers and industrial practitioners working in the fields of agriculture, aquaculture and public health.
This book provides a snapshot of representative modeling analyses of coastal hypoxia and its effects. Hypoxia refers to conditions in the water column where dissolved oxygen falls below levels that can support most metazoan marine life (i.e., 2 mg O2 l-1). The number of hypoxic zones has been increasing at an exponential rate since the 1960s; there are currently more than 600 documented hypoxic zones in the estuarine and coastal waters worldwide. Hypoxia develops as a synergistic product of many physical and biological factors that affect the balance of dissolved oxygen in seawater, including temperature, solar radiation, wind, freshwater discharge, nutrient supply, and the production and decay of organic matter. A number of modeling approaches have been increasingly used in hypoxia research, along with the more traditional observational and experimental studies. Modeling is necessary because of rapidly changing coastal circulation and stratification patterns that affect hypoxia, the large spatial extent over which hypoxia develops, and limitations on our capabilities to directly measure hypoxia over large spatial and temporal scales. This book consists of 15 chapters that are broadly organized around three main topics: (1) Modeling of the physical controls on hypoxia, (2) Modeling of biogeochemical controls and feedbacks, and, (3) Modeling of the ecological effects of hypoxia. The final chapter is a synthesis chapter that draws generalities from the earlier chapters, highlights strengths and weaknesses of the current state-of-the-art modeling, and offers recommendations on future directions.
"Diagnosing Wild Species Harvest" bridges gaps of knowledge fragmented among scientific disciplines as it addresses this multifaceted phenomenon that is simultaneously global and local. The authors emphasize the interwoven nature of issues specific to the ecological, economic, and socio-cultural realms of wild species harvest. The book presents the diagnosing wild species harvest procedure as a universal approach that integrates seven thematic perspectives to harvest systems: resource dynamics, costs and benefits, management, governance, knowledge, spatiality, and legacies. When analyzed, these themes help to build a holistic understanding of this globally important phenomenon. Scholars, professionals and students in various fields related to natural resources will find the book a valuable resource. Wild species form important resources for people worldwide, and
their harvest is a major driver of ecosystem change. Tropical
forests regions, including Amazonia, are among those parts of the
world where wild species are particularly important for people's
livelihoods and larger economies. This book draws on tangible
experiences from Amazonia, presented in lively narratives
intermingling scientific information with stories of the people
engaged in harvest and management of wild species. These stories
are linked to relevant theory of wild species harvest and wider
discussions on conservation, development, and the global quest of
sustainability.
Today, the East African state of Tanzania is renowned for wildlife preserves such as the Serengeti National Park, the Ngorongoro Conservation Area, and the Selous Game Reserve. Yet few know that most of these initiatives emerged from decades of German colonial rule. This book gives the first full account of Tanzanian wildlife conservation up until World War I, focusing upon elephant hunting and the ivory trade as vital factors in a shift from exploitation to preservation that increasingly excluded indigenous Africans. Analyzing the formative interactions between colonial governance and the natural world, The Nature of German Imperialism situates East African wildlife policies within the global emergence of conservationist sensibilities around 1900.
Adaptive management is an approach to managing social-ecological systems that fosters learning about the systems being managed and remains at the forefront of environmental management nearly 40 years after its original conception. Adaptive management persists because it allows action despite uncertainty, and uncertainty is reduced when learning occurs during the management process. Often termed "learning by doing", the allure of this management approach has entrenched the concept widely in agency direction and statutory mandates across the globe. This exceptional volume is a collection of essays on the past, present and future of adaptive management written by prominent authors with long experience in developing, implementing, and assessing adaptive management. Moving forward, the book provides policymakers, managers and scientists a powerful tool for managing for resilience in the face of uncertainty.
This book addresses the impacts of current and future reproductive technologies on our world food production and provides a significant contribution to the importance of research in the area of reproductive physiology that has never been compiled before. It would provide a unique opportunity to separate the impacts of how reproductive technologies have affected different species and their contributions to food production. Lastly, no publication has been compiled that demonstrates the relationship between developments in reproductive management tools and food production that may be used a reference for scientists in addressing future research areas. During the past 50 years assisted reproductive technologies have been developed and refined to increase the number and quality of offspring from genetically superior farm animal livestock species. Artificial insemination (AI), estrous synchronization and fixed-time AI, semen and embryo cryopreservation, multiple ovulation and embryo transfer (MOET), in vitro fertilization, sex determination of sperm or embryos, and nuclear transfer are technologies that are used to enhance the production efficiency of livestock species. |
