The value of planet Earth's biodiversity has been estimated at US
$16-54 trillion per year. Trillions of dollars of food, raw
materials, pharmaceuticals, oxygen production, soil nutrient
enrichment, climate regulation and sheer aesthetic delight and
wonder. We are reliant on biodiversity to keep the plant healthy
and resilient.
Islands are special because they promote unique forms of life, and large proportions of the species they hold are found nowhere else on Earth. The mammals of the South-west Pacific are no exception, with many distributed only across single islands or archipelagos. Mammals of the South-west Pacific details the natural history for more than 180 species of marsupials, bats and rodents from 24 Pacific nations and territories. Species profiles are accompanied by distribution maps, illustrations and photographs – many being the first images ever captured for the species. By combining available knowledge with unpublished data collected over years of field work, Mammals of the South-west Pacific forms a definitive guide to the mammals from this region.
This volume investigates the challenges facing the Egyptian Northern coastal lakes, focusing on the impact of climate change, their biodiversity and sustainable management. Presenting up-to-date research, it covers the following topics: climate change and water quality modeling and their impacts on the sustainability of the lakes; the economic role of the lakes; the use of remote sensing in monitoring; and the biodiversity of the lakes with detailed discussions. Further, management strategies for the sustainable development of these valuable resources are proposed to maintain the lakes sustainability. The book closes with a concise summary of the conclusions and recommendations presented in the preceding chapters. As such, it offers an invaluable resource for the academic community and postgraduate students, as well as for environmental managers and policymakers.
Animals are a major link between the water column (pelagic) and the bottom (benthic) habitats in most shallow systems. This coupling is dominated by active processes such as suspension-feeding in which the organism actively uses energy to pump water that is then filtered to remove suspended particles that are consumed while undigested remains are deposited on the bottom. As a result of this feeding on and metabolism of particles, the animals excrete dissolved inorganic and organic waste back into the water column, and thus, become major components in the cycling and feedback of essential elements. With relatively high weight specific filtration rates of 1a" 10 liters/hour/gram dry tissue and a propensity to form large aggregated populations (beds, reefs, schools and swarms), these organisms can play an important role in regulating water column processes. Although estuarine bivalve molluscs such as oysters and mussels dominate the suspension-feeder literature, other groups including plankton and nekton that are found in estuarine as well as other aquatic systems are also potentially important removers of suspended particles. Thus, a significant part of the NATO Advanced Research Workshop focused on suspension-feeders as controllers of plankton abundance, biomass and diversity, system metabolism, nutrient cycling and scale dependency. Systems dominated by suspension-feeders are typically impacted by human activities including recreation, aquaculture, human and industrial pollution, and bilge water from shipping. Suspension-feeders are often impacted by fisheries and over-exploitation. These impacts commonly result in changes in ecosystem structure either through the food chainconcentration of harmful substances or diseases, the introduction of alien species of suspension-feeders, or the instability of suspension-feeders systems through species displacement or phase shifts in the dominance between different suspension-feeding components such as nekton or zooplankton. These issues were addressed near the close of the workshop along with conclusions and syntheses developed by the working groups.
An important prerequisite for successful conservation is a good understanding of what we seek to conserve. Nowhere is this more the case than in the fight to protect plant biodiversity, which is threatened by human activity in many regions worldwide. This book is written in the belief that tools that enable more people to understand biodiversity can not only aid protection efforts but also contribute to rural livelihoods. Among the most important of those tools is the field guide.Plant Identification provides potential authors of field guides with practical advice about all aspects of producing user-friendly guides which help to identify plants for the purposes of conservation, sustainable use, participatory monitoring or greater appreciation of biodiversity. The book draws on both scientific and participatory processes, supported by the experience of contributors from across the tropics. It presents a core process for producing a field guide, setting out key steps, options and techniques available to the authors of a guide and, through illustration, helps authors choose methods and media appropriate to their context.
The book collects a selection of the papers presented at the meeting held in the context of the Joint Programme on the Links between Biological and Cultural Diversity (JP-BiCuD). Recognizing the inextricable link between biological and cultural diversity, the United Nations Educational Scientific and Cultural Organization (UNESCO) and the Secretariat of the Convention on Biological Diversity (SCBD) joined forces, and in 2010 launched the Joint Programme on the Links between Biological and Cultural Diversity (JP-BiCuD). The first meeting for the implementation of the JP-BiCuD was held in Florence (Italy) in April 2014 and produced the UNESCO-sCBD Florence Declaration, which highlights the concept of biocultural diversity. The European rural territory is predominantly a biocultural, multi-functional landscape, providing a crucial and effective space for integration of biological and cultural diversity, suggesting the need to revise some of the current strategies for the assessment and management of biodiversity.
The species-area relationship (SAR) describes a range of related phenomena that are fundamental to the study of biogeography, macroecology and community ecology. While the subject of ongoing debate for a century, surprisingly, no previous book has focused specifically on the SAR. This volume addresses this shortfall by providing a synthesis of the development of SAR typologies and theory, as well as empirical research and application to biodiversity conservation problems. It also includes a compilation of recent advances in SAR research, comprising novel SAR-related theories and findings from the leading authors in the field. The chapters feature specific knowledge relating to terrestrial, marine and freshwater realms, ensuring a comprehensive volume relevant to a wide range of fields, with a mix of review and novel material and with clear recommendations for further research and application.
This book is a celebration of the humble gudgeon, the angler's favourite 'tiddler'. This much-loved little fish is long overdue a little book all of its own. Scientist, author and broadcaster Dr Mark Everard tells tales about the biology of the gudgeon, gudgeon fishing, and the diverse social quirks and values of this most popular of little fishes.
There is a rapidly growing interest in, and demand for, non-timber forest products (NTFPs). They provide critical resources across the globe fulfilling nutritional, medicinal, financial and cultural needs. However, they have been largely overlooked in mainstream conservation and forestry politics. This volume explains the use and importance of certification and eco-labelling for guaranteeing best management practices of non-timber forest products in the field. Using extensive case studies and global profiles of non-timber forest products, this work not only seeks to further our comprehension of certification processes but also broaden understanding of non-timber forest product management, harvesting and marketing. It should be useful to forest managers, policy-makers and conservation organizations as well as for academics in these areas.
This edited volume addresses a rising concern among natural resource scientists and management professionals about decline of the many plant and animal species associated with early-successional habitats, especially within the Central Hardwood Region of the USA. These open habitats, with herbaceous, shrub, or young forest cover, are disappearing as abandoned farmland, pastures, and cleared forest patches return to forest. There are many questions about "why, what, where, and how" to manage for early successional habitats. In this book, expert scientists and experienced land managers synthesize knowledge and original scientific work to address questions on such topics as wildlife, water, carbon sequestration, natural versus managed disturbance, future scenarios, and sustainable creation and management of early successional habitat in a landscape context.
This volume presents technical papers devoted to development and practical use of computer methods in geotechnical and geoenviromental engineering. It covers issues on space use and construction, soil and rock mechanics, and mining applications amongst other topics.
This book deals with the economic potentials of biodiversity and its capacity to support its own conservation aiming to provide livelihood for millions engaged in conservation, both now and for future generations. The book highlights the potentials of natural resources which are characterized as capital wealth (as defined in Convention on Biological Diversity (CBD)), to finance its own conservation and to provide livelihood means to people who conserve it. The book is divided into five Parts. PART I explains about the Premise of Access and Benefit Sharing (ABS), PART II describes about the Technology Transfer, PART III will provide details about the Access to Genetic Resources and Access to Associated Traditional Knowledge & Benefit Sharing, PART IV is the Implementation of ABS mechanisms and PART V is about ABS and its Economics. This book will be of interest to biodiversity policy makers, administrators, university and college students, researchers, biodiversity conservationists.
Environmental DNA (eDNA) refers to DNA that can be extracted from environmental samples (such as soil, water, feces, or air) without the prior isolation of any target organism. The analysis of environmental DNA has the potential of providing high-throughput information on taxa and functional genes in a given environment, and is easily amenable to the study of both aquatic and terrestrial ecosystems. It can provide an understanding of past or present biological communities as well as their trophic relationships, and can thus offer useful insights into ecosystem functioning. There is now a rapidly-growing interest amongst biologists in applying analysis of environmental DNA to their own research. However, good practices and protocols dealing with environmental DNA are currently widely dispersed across numerous papers, with many of them presenting only preliminary results and using a diversity of methods. In this context, the principal objective of this practical handbook is to provide biologists (both students and researchers) with the scientific background necessary to assist with the understanding and implementation of best practices and analyses based on environmental DNA.
The goal of this transdisciplinary book is to identify the problems and challenges facing implementation of the Convention on Biological Diversity (CBD) - from the global, regional and local points of view. The valuation and conservation of biodiversity are critical first steps necessary for the adequate protection of the environment. The authors give insights into the the influences the CBD exerts, and current trends in the field.
This book brings together a selection of original studies submitted to Biodiversity and Conservation that address the conservation and biodiversity of vertebrates - particularly those in terrestrial habitats. Vertebrates are, along with plants, the best-known and most intensively studied components of biological diversity on Earth. While studies on vertebrates can be expected to provide models for other groups, they can also pose their own particular problems due to their relative mobility as in some migratory birds. In addition, many mammals & fish are also subject to extensive human exploitation for food or sport. The contributions in this volume are drawn from a wide range of countries - from Australasia, East Africa, Europe, and North, Central and South America. Collectively they provide a snap-shot of the types of studies and actions being taken in vertebrate conservation.
This book provides the first collection of chapters written by scientists who have contributed to the understanding of disease ecology in the Galapagos Islands, an iconic and historic natural site. The Galapagos Archipelago straddles the equator in the eastern Pacific Ocean, almost 1000 km off the coast of Ecuador, and includes 13 major islands, numerous smaller satellite islands, and many more even smaller islets. The wildlife on the Galapagos Islands today represents one of the best-preserved wild communities of plants and animals in the world, owing to the location of the islands at the intersection of major ocean currents, the commitment by Ecuador for the vast majority of the area to be left undeveloped, and the protection provided by the Galapagos National Park. Most of the animal species in Galapagos are endemic, occurring nowhere else. But they are descendants of ancestors that colonized earlier, and then, isolated from their mainland origins, evolved into forms that are recognized as distinct today. Since 2001, many of the authors of this book have been part of a four-institution partnership investigating the threats posed by pathogens to Galapagos avifauna. They approach the topic of disease ecology in a novel manner, starting with the history of arrival of both the birds themselves and the pathogens. This synthetic approach requires the integration of themes from veterinary medicine, epidemiology, population genetics, and phylogenetics.
Animal welfare has long been recognised as central to the role of the veterinary professional, but this is increasingly aligned with the welfare of humans and the broader environment in which we co-exist. This is the first book dedicated to the role of the veterinarian in One Welfare, a concept that recognises the interconnections between animal welfare, human wellbeing, and the environment. The book demonstrates, through a wide range of international case studies, why professional ethics and the use of good evidence is integral to this role. Contributors bring a rich variety of writings, each with their own perception of the role of the veterinarian in improving animal welfare and human wellbeing. One Welfare in Practice: The Role of the Veterinarian emphasises the importance of interdisciplinary collaboration and solutions: it is essential that veterinary practitioners recognise when other professionals or disciplines need to be consulted to benefit both animals and humans. With its multiple, fascinating approaches to One Welfare, this book will inform and inspire the veterinarian to find areas where collaborative action reaps the greatest rewards. This unique book shows how veterinarians can and are contributing to improving animal and human welfare, offering practical advice as to how the profession can further engage in One Welfare in a range of settings.
Wheat (Triticum L.), an annual herbaceous plant in Poacae (Gramineae) family, settles in the Triticeae (Hordeae) subfamily. The grasses (Poaceae Barnhart) are the fifth largest (monocotyledonous flowering) plant family and of great importance for human civilization and life. Cereal crops such as maize, wheat, rice, barley, and millet are the domesticated ones in the family. It is still the most vital economical plant family in modern times, providing food, forage, building materials (bamboo, thatch), and fuel (ethanol). Wheat has many accessions in national and international gene banks. The estimated number of wheats by FAO in 2010 is 856,000, and, followed by rice (774,000), and barley (467,000). However, the recent consumer's (misdirected) focus on gluten content and nutritional value urges scientists to reexamine their knowledge about wheat (i.e., origin, evolution, and general and special quality characteristics), as well as their wild relatives and landraces for newer possible genetic resources. Cultured or non-cultured ancestral wheats: einkorn, emmer, wild emmer, spelt, macha, and vavilovii are still limitedly grown on the higher areas in Turkey, Italy, Germany, Morocco, Israel, and Balkan countries. They are exploited mostly for their desired agronomic, and specific quality. In some cultures, wheat species are believed to be therapeutic, with bioactive compounds that reduce and inhibit stubborn illnesses such as diabetes, cancer, Alzheimer, and cardiovascular diseases. In this book, we summarize the importance of ancestral wheat species, and provide a prospect for their future with special considerations in terms of species conservation and improvement.

The last chapter is specifically designed to help you get started.
The book provides a comprehensive account of a tropical lake, Alchichica, considering that tropical limnology is by far less known and well-understood than temperate. Many of the well-known temperate limnology paradigms do not apply in tropical limnology, such as the 1C/m thermocline concept, or the role of phosphorous as a limiting nutrient. Lake Alchichica is - most likely - the best limnologically known Mexican lake up to date. Twenty years of continuous monitoring has led us to understand this deep, warm monomictic lake. The peculiar chemical composition of this saline lake - sodium-alkaline with a high concentration in magnesium waters, and groundwater-fed - led to the formation of its unique stromatolite ring that has become world-famous, studied by scientists from various countries. From a biological point of view, this relatively small maar lake displays a comparatively low species richness but surprisingly is plentiful in microendemic species for a recently-formed lake (13,000-6,300 years old, at the Late Pleistocene/Holocene Epoch), eleven of which already described, with more to come. Researchers and students interested in tropical limnology, extreme ecosystems, evolutionary biology, astrobiology, and microbiology will find this book a must-read.
This volume considers current and future challenges for nature law and policy in Europe. Following the Fitness Check evaluation of the Birds and Habitats Directives, in 2017 the EU adopted an Action Plan for nature, people and the economy to rapidly improve the Directives' implementation and accelerate progress towards the EU's biodiversity targets for 2020. More recently, the EU has adopted a Biodiversity Strategy for 2030 and proposed an EU Nature Restoration Law. This book makes a timely contribution by examining the current state of play in light of recent and historical developments, as well as the post-2020 nature law and policy landscape. While evidence suggests that Natura 2000 and the Habitats and Birds Directives have delivered conservation benefits for wildlife in Europe, biodiversity loss continues apace. The book reviews the requirements for an effective international nature conservation system, with reference to the Birds and Habitats Directives. It examines regulatory regimes, current legal issues in the fields of site protection and species protection, the protection of areas outside Natura 2000, recent developments in the EU and the UK, including the implications of Brexit, agriculture and nature conservation, litigation, science and access to justice. Written by leading experts in the field, from a range of stakeholder groups, the volume draws on diverse experiences as well as providing interdisciplinary perspectives. This volume will be essential reading for students and scholars interested in European environmental policy and law, including lawyers, ecologists, environmental scientists, political scientists, natural resource managers, and planners. It will also be of interest to conservation practitioners, policy-makers and NGOs.
The seventh volume in the series "Ethology and Behavioral Ecology of Marine Mammals" describes aspects of the often-complex relationship between humans and marine mammals. From a primeval condition of occasional predators, during the last century humans have become a major factor negatively affecting the status of most marine mammals through over-hunting, habitat encroachment and environmental degradation. This has led to the extirpation of many marine mammal populations and even to the extinction of species. However, in parallel to this destructive drive, since antiquity humanity has been influenced by a strong fascination for marine mammals, which contributes today to an increased human appreciation of the natural world admixed with widespread concern for its degrading condition. The special status occupied by marine mammals in human imagination and affection stands in stark contrast with the current predicament of many populations still threatened by the doings of Homo sapiens: a condition emblematic of the relationship of humanity with nature, and key to understanding where humanity is heading.
