The capacity of mixed forests to mitigate climate change effects by increasing resilience and lowering risks is pinpointed as an opportunity to highlight the role of tree species rich forests as part of complex socio-ecological systems. This book updates and presents the state-of-the-art of mixed forest performance in terms of regeneration, growth, yield and delivery of ecosystem services. Examples from more than 20 countries in Europe, North Africa and South America provide insights on the interplay between structure and functionining, stability, silviculture and optimization of management of this type of forests. The book also analyses the role of natural mixed forests and mixed plantations in the delivery of ecosystem services and the best modelling strategy to study mixed forest dynamics. The book is intended to serve as a reference tool for students, researchers and professionals concerned about the management of mixed forests in a context of social and environmental change.
We don't know what we've got until it's gone... This brief, lucid book by the Director of Science at Royal Botanical Gardens takes you on an unforgettable tour of the natural world, showing how biodiversity - the rich variety of life in the world and in our own backyards - provides both the source and the salvation of our existence. Combining inspiration stories and the latest scientific research, Alex Antonelli reveals the wonders of biodiversity at a genetic, species and ecosystem level - what it is, how it works, and why it's the most important tool in our battle against climate change. A deeper understanding of biodiversity has never been more important, as the slow violence of habitat loss has put the fate of almost one-fifth of all species on Earth at risk of extinction in the coming decades. These building blocks of life form a network that underpins almost every aspect of our lives, providing invaluable sources of food, medicine, fibre, clothing, building material and more. With simplicity and clarity, The Hidden Universe shows you not only what's at stake, but what can be done (and is already being done) to protect and restore biodiversity around the world. It marks the arrival of a bold new voice in popular science.
Winner of the 2022 Marsh Book of the Year Award A long-awaited volume in the New Naturalist series examining the trees of Britain. Trees are immensely valuable. They give shape to our lives with wood, the material that makes our homes, our books, our belongings; they nourish us with the air we breathe and the fruits we eat; and they sustain us, with their shade and the comfort of their presence. They are also fascinating - they are the biggest and oldest living organisms on the planet and are essential components of many of the landscapes of Britain. Trees have been vital in determining the ecology of our planet as well as the development of human cultures and communities, yet how much do we really understand about them? How do trees live? How do they fit into their environments? Why are they so important to ecosystems on earth, and to us? And what does the future hold for trees? Can they solve the problems of climate change by absorbing enough carbon dioxide, and would we run out of oxygen if all the world's trees disappeared? Do trees really talk to each other? There is much to learn about these silent giants. Ecologist Peter Thomas explores all these questions and many more, delving into the often hidden life of trees, using examples from around the world, from common trees to the unusual and bizarre. This comprehensive introduction to all aspects of tree biology and ecology presents the latest scientific and botanical discoveries and explores the wonders and mysteries of trees.
Using more than 30 years research from the author team at the Wildlife Conservation Research Unit (WildCRU), this volume reveals how agricultural systems and wildlife interact, presenting examples from scales varying from landscape to microcosm, from populations to individuals, covering plants, invertebrates, birds, and mammals. It demonstrates the essential ecosystem services provided by agricultural land, and discusses the implications of agricultural development for natural habitats and biodiversity.
Mutualisms, interactions between two species that benefit both of them, have long captured the public imagination. Their influence transcends levels of biological organization from cells to populations, communities, and ecosystems. Mutualistic symbioses were crucial to the origin of eukaryotic cells, and perhaps to the invasion of land. Mutualisms occur in every terrestrial and aquatic habitat; indeed, ecologists now believe that almost every species on Earth is involved directly or indirectly in one or more of these interactions. Mutualisms are essential to the reproduction and survival of virtually all organisms, as well as to nutrient cycles in ecosystems. Furthermore, the key ecosystem services that mutualists provide mean that they are increasingly being considered as conservation priorities, ironically at the same time as the acute risks to their ecological and evolutionary persistence are increasingly being identified. This volume, the first general work on mutualism to appear in almost thirty years, provides a detailed and conceptually-oriented overview of the subject. Focusing on a range of ecological and evolutionary aspects over different scales (from individual to ecosystem), the chapters in this book provide expert coverage of our current understanding of mutualism whilst highlighting the most important questions that remain to be answered. In bringing together a diverse team of expert contributors, this novel text captures the excitement of a dynamic field that will help to define its future research agenda.
"If you're looking for a dose of wonder in your reading life, I recommend this beautiful book about the magic of fig trees."-Book Riot Over millions of years, fig trees have shaped our world, influenced our evolution, nourished our bodies and fed our imaginations. And as author and ecologist Mike Shanahan proclaims, "The best could be yet to come." Gods, Wasps and Stranglers weaves together the mythology, history and ecology of one of the world's most fascinating-and diverse-groups of plants, from their starring role in every major religion to their potential to restore rainforests, halt the loss of rare and endangered species and even limit climate change. In this lively and joyous book, Shanahan recounts the epic journeys of tiny fig wasps, whose eighty-million-year-old relationship with fig trees has helped them sustain more species of birds and mammals than any other trees; the curious habits of fig-dependent rhinoceros hornbills; figs' connection to Krishna and Buddha, Jesus and Muhammad; and even their importance to Kenya's struggle for independence. Ultimately, Gods, Wasps and Stranglers is a story about humanity's relationship with nature, one that is as relevant to our future as it is to our past.
South Africa's fynbos region has intrigued biologists for centuries. It has achieved iconic status as a locus of megadiversity and therefore a place to study the ecological underpinnings of massive evolutionary radiations. Researchers have made great advances over the past two decades in unravelling the complexities of fynbos ecology and evolution, and the region has contributed significant insights into the adaptive radiations of large lineages, conservation science, pollination biology, invasive plant biology, and palaeoanthropology. Lessons from the fynbos offer much of value for understanding the origin, maintenance, and conservation of diversity anywhere in the world. This book provides the first synthesis of the field for 20 years, bringing together the latest ecological and evolutionary research on the South African global biodiversity hotspots of the Greater Cape Floristic Region - the iconic fynbos and succulent karoo. It explores the historical and modern physical and biological environment of this region, the circumstances and processes which have fostered its remarkable biodiversity, and the role this diversity has played in the emergence of modern humans. It also discusses the challenges of contemporary management and conservation of the region's biodiversity in the face of accelerating global change.
The biological composition and richness of most of the Earth's
major ecosystems are being dramatically and irreversibly
transformed by anthropogenic activity. Yet, despite the vast areal
extent of our oceans, the mainstay of research to-date in the
biodiversity-ecosystem functioning arena has been weighted towards
ecological observations and experimentation in terrestrial plant
and soil systems. This book provides a framework for examining the
mechanistic processes transferable to marine systems.

Ecologists, land managers and policymakers continue to search for the most effective ways to manage biological invasions. An emerging lesson is that proactive management can limit negative impacts, reduce risks and save money. This book explores how to detect and respond to alien plant incursions, summarising the most current literature, providing practical recommendations and reviewing the conditions and processes necessary to achieve prevention, eradication and containment. Chapter topics include assessing invasiveness and the impact of alien plants, how to improve surveillance efforts, how to make timely management decisions, and how legislation and strategic planning can support management. Each chapter includes text boxes written by international experts that discuss topical issues such as spatial predictive modelling, costing invasions, biosecurity, biofuels, and dealing with conflict species.
This second part of Volume 48 of the Flora of Pan-Himalaya is devoted to the single genus, Saussurea of the Asteraceae family, which has wide medicinal applications. This is the largest family in the Pan-Himalaya, with 235 species, 149 of which are endemic to the Pan-Himalaya. Saussurea is a notoriously difficult, largely Asiatic, genus with often indistinct species boundaries. Many new species of Saussurea were described in the course of preparing this account. The nomenclatural novelties in this volume include five changes in status, and 17 new synonyms. 27 lectotypes are newly designated. During the research for this volume, the author and his team described 40 new species of Saussurea, and these, along with numerous new designations and classifications, are recorded here for the first time.
This open access book is an original contribution to the knowledge on fishing and research associated with one of the most enigmatic fish of our seas: bluefin tuna, Thunnus thynnus (L.). Based on available evidence, it reconstructs the possible methods used to catch large spawners in the Strait of Gibraltar thousands of years ago and describes the much more recent overfishing that led to a great reduction in the catches of the trap fishery on the area and the disappearance of the northern European fisheries. It is the first book to relate the overfishing of juvenile fishes in certain areas to the decline of large spawners in other very distant areas, revealing one of the main underlying causes of this decline, which has remained a mystery to the fishing sector and scientists alike for over 50 years. This finding should serve to prevent similar cases from arising in the future.
Biological Diversity provides an up to date, authoritative review of the methods of measuring and assessing biological diversity, together with their application. The book's emphasis is on quantifying the variety, abundance, and occurrence of taxa, and on providing objective and clear guidance for both scientists and managers. This is a fast-moving field and one that is the focus of intense research interest. However the rapid development of new methods, the inconsistent and sometimes confusing application of old ones, and the lack of consensus in the literature about the best approach, means that there is a real need for a current synthesis. Biological Diversity covers fundamental measurement issues such as sampling, re-examines familiar diversity metrics (including species richness, diversity statistics, and estimates of spatial and temporal turnover), discusses species abundance distributions and how best to fit them, explores species occurrence and the spatial structure of biodiversity, and investigates alternative approaches used to assess trait, phylogenetic, and genetic diversity. The final section of the book turns to a selection of contemporary challenges such as measuring microbial diversity, evaluating the impact of disturbance, assessing biodiversity in managed landscapes, measuring diversity in the imperfect fossil record, and using species density estimates in management and conservation.
Comprising a substantial part of living biomass on earth, ants are
integral to the functioning of terrestrial ecosystems. More than
12,500 species have been described to date, and it is estimated
that perhaps as many still await classification.
Caribbean coral reefs have unique species, are the world’s second largest coral reef community, and the most threatened. This book will be of major interest to all concerned with saving coral reefs from extinction. No other book available shows Caribbean coral reefs when they were at their best. It is only by comparing the images in this book with what they see now that people can recognize what we have lost. It is far more than they can imagine! Those who did not see it themselves can only do so through this book. Jim Porter’s insightful commentary in the Foreword adds crucial scientific perspective. Other books do not provide a one volume summary of all the major species on the Caribbean reef. This book is also more accurate in important systematic organization than other books in this field. The author’s excellent photographs convey clear concepts of processes and key aspects of species for identification. The book is written in an engaging story-telling style, yet clearly and concisely communicating the essential scientific concepts. Whereas most books have chapters dividing up one topic, this book is divided into different kinds of information which are essential to understanding coral reefs: how reefs are structured, corals, invertebrates, fishes, cryptic or hidden organisms, the community at night and others. One review states "After 52 years of researching coral reefs, I find this is the best book to present what reefs should be like, and were like 50 years ago. It is also written in a style accessible to recreational divers who wish to know the organisms, processes, and structures they are seeing." Another says "The first thing that will strikes the reader is the exquisite photography. There are many great underwater photographers, but the author is in a class by himself. Once the first impact of the astounding photography is accepted, the reader will be struck by what might be called the scientific integrity of the book." While this book is 'a time machine' taking the reader back to when these reefs thrived, there is optimism that we may see these reefs again as they appear in this book.

How will biodiversity loss affect ecosystem functioning, ecosystem
services, and human well-being?
Published in three other languages and growing, "Managing Biodiversity in Agricultural Ecosystems" takes a look at how farmers manage, maintain, and benefit from biodiversity in agricultural production systems. The volume includes the most recent research and developments in the maintenance of local diversity at the genetic, species, and ecosystem levels. Chapters cover the assessment and farmer management practices for crop, livestock, aquatic, and associated diversity (such as pollinators and soil microorganisms) in agricultural ecosystems; examine the potential role of diversity in minimizing pest and disease pressures; and present studies that exemplify the potential nutritional, ecosystem service, and financial values of this diversity under changing economic and environmental conditions. The volume contains perspectives that combine the thinking of social and biological scientists. Inappropriate or excessive use of inputs can cause damage to biodiversity within agricultural ecosystems and compromise future productivity. This book features numerous case studies that show how farmers have used alternative approaches to manage biodiversity to enhance the stability, resilience, and productivity of their farms, pointing the way toward improved biodiversity on a global scale. As custodians of the world's agricultural biodiversity, farmers are fully invested in ways to create, sustain, and assist in the evolution and adaptation of a variety of plant and animal species. Thus this text is mandatory reading for conservationists, environmentalists, botanists, zoologists, geneticists, and anyone interested in the health of our ecosystem.
Over the last decade, molecular studies carried out on the Australasian biota have revealed a new world of organic structure that exists from submicroscopic to continental scale. Furthermore, in studies of global biogeography and evolution, DNA sequencing has shown that many large groups, such as flowering plants, passerine birds and squamates, have their basal components in this area. Using examples ranging from kangaroos and platypuses to kiwis and birds of paradise, the book examines the patterns of distribution and evolution of Australasian biodiversity and explains them with reference to tectonic and climatic change in the region. The surprising results from molecular biogeography demonstrate that an understanding of evolution in Australasia is essential for understanding the development of modern life on Earth. A milestone in the literature on this subject, this book will be a valuable source of reference for students and researchers in biogeography, biodiversity, ecology and conservation.
There are fewer grey seals in the world than endangered African elephants, but the British Isles host almost half of this global population. Every year these charismatic animals, with their expressive eyes and whiskers more sensitive than our fingertips, haul out on our shores to breed and raise their pups. Susan Richardson has always been entranced by seals; they seem to have surfaced at key junctions throughout her life, comforting her as an anxious child, bringing joy as she began to spread her wings as a writer and helping her to find her way after the loss of her mother. Now she sets out to trace the rhythm of their lives, travelling the coasts clockwise from Cornwall to Norfolk, in line with the autumn pupping season. Along the way she explores the myths surrounding seals, from their shapeshifting selkie skins to the claims that they decimate fish populations, and she discovers that the greatest dangers they face come from co-existing with us. Brimming with vivid descriptions of the natural world, Where the Seals Sing is a lyrical tale of memory, rescue and rehabilitation. While loss, both personal and ecological, is a recurring theme, the human-seal connection that flows through the story is stirring and uplifting.
A balanced review of differing approaches based on remote sensing tools and methods to assess and monitor biodiversity, carbon and water cycles, and the energy balance of terrestrial ecosystem. Earth Observation of Ecosystem Services highlights the advantages Earth observation technologies offer for quantifying and monitoring multiple ecosystem functions and services. It provides a multidisciplinary reference that expressly covers the use of remote sensing for quantifying and monitoring multiple ecosystem services. Rather than exhaustively cover all possible ecosystem services, this book takes a global look at the most relevant remote sensing approaches to estimate key ecosystem services from satellite data. Structured in four main sections, it covers carbon cycle, biodiversity, water cycle, and energy balance. Each section contains a review of conceptual and empirical methods, techniques, and case studies linking remotely sensed data to the biophysical variables and ecosystem functions associated with key ecosystem services. The book identifies relevant issues and challenges of assessment, presents cutting-edge sensing techniques, uses globally implemented tools to quantify ecosystem functions, and presents examples of successful monitoring programs. Covering recent developments undertaken on the global and national stage from Earth observation satellite data, it includes valuable lessons and recommendations and novel ways to improve current global monitoring systems. The book delineates the use of Earth observation data so that it can be used to quantify, map, value, and manage the valuable goods and services that ecosystems provide to societies around the world.
"Wild Profusion" tells the fascinating story of biodiversity conservation in Indonesia in the decade culminating in the great fires of 1997-98--a time when the country's environment became a point of concern for social and environmental activists, scientists, and the many fishermen and farmers nationwide who suffered from degraded environments and faced accusations that they were destroying nature. Celia Lowe argues that biodiversity, in 1990s Indonesia, implied a particular convergence of nature, nation, science, and identity that made Indonesians' mapping of the concept distinct within transnational practices of nature conservation at the time. Lowe recounts the efforts of Indonesian biologists to document the species of the Togean Islands, to "develop" Togean people, and to turn this archipelago off the coast of Sulawesi into a national park. Indonesian scientists aspired to a conservation biology that was both internationally recognizable and politically effective in the Indonesian context. Simultaneously, Lowe describes the experiences of Togean Sama people who had their own understandings of nature and nation. To place Sama and scientist into the same conceptual frame, Lowe studies Sama ideas in the context of transnational thought rather than local knowledge. In tracking the practice of conservation biology in a postcolonial setting, "Wild Profusion" explores what in nature can count as important and for whom.
This book sets out the building blocks of an economic approach to biodiversity, and in particular brings together conceptual and empirical work on valuation, international agreements, the policy instruments, and the institutions. The objective is to provide a comprehensive overview of the issues and evidence, and to suggest how this very urgent problem should be addressed. Whilst there has been an enormous growth and research focus on climate change, less attention has been paid to biodiversity. This collection of high-quality chapters addresses the economic issues involved in biodiversity protection. This book focuses on the economics, but incorporates the underpinning science and philosophy, combining the application of a number of theoretical ideas with a series of policy cases. The authors are drawn from leading scholars in their specific areas of economics, philosophy, and conservation biology.

With practical advice on everything from messages and metaphors to metrics and ethics, you will learn what the public think about science and why, and how to shape scientific research into a story that will influence beliefs, behaviours and policies.
With more than 500 species distributed all around the Northern Hemisphere, the genus Quercus L. is a dominant element of a wide variety of habitats including temperate, tropical, subtropical and mediterranean forests and woodlands. As the fossil record reflects, oaks were usual from the Oligocene onwards, showing the high ability of the genus to colonize new and different habitats. Such diversity and ecological amplitude makes genus Quercus an excellent framework for comparative ecophysiological studies, allowing the analysis of many mechanisms that are found in different oaks at different level (leaf or stem). The combination of several morphological and physiological attributes defines the existence of different functional types within the genus, which are characteristic of specific phytoclimates. From a landscape perspective, oak forests and woodlands are threatened by many factors that can compromise their future: a limited regeneration, massive decline processes, mostly triggered by adverse climatic events or the competence with other broad-leaved trees and conifer species. The knowledge of all these facts can allow for a better management of the oak forests in the future. |
