Carbon moves through the atmosphere, through the oceans, onto land, and into ecosystems. This cycling has a large effect on climate - changing geographic patterns of rainfall and the frequency of extreme weather - and is altered as the use of fossil fuels adds carbon to the cycle. The dynamics of this global carbon cycling are largely predicted over broad spatial scales and long periods of time by Earth system models. This book addresses the crucial question of how to assess, evaluate, and estimate the potential impact of the additional carbon to the land carbon cycle. The contributors describe a set of new approaches to land carbon cycle modeling for better exploring ecological questions regarding changes in carbon cycling; employing data assimilation techniques for model improvement; and doing real- or near-time ecological forecasting for decision support. This book strives to balance theoretical considerations, technical details, and applications of ecosystem modeling for research, assessment, and crucial decision making. Key Features Helps readers understand, implement, and criticize land carbon cycle models Offers a new theoretical framework to understand transient dynamics of land carbon cycle Describes a suite of modeling skills - matrix approach to represent land carbon, nitrogen, and phosphorus cycles; data assimilation and machine learning to improve parameterization; and workflow systems to facilitate ecological forecasting Introduces a new set of techniques, such as semi-analytic spin-up (SASU), unified diagnostic system with a 1-3-5 scheme, traceability analysis, and benchmark analysis, for model evaluation and improvement Related Titles Isabel Ferrera, ed.

Ranunculus offers advice on how to care for and propagate these colourful cultivated members of the buttercup family. Naomi Slade explores a wide range of ranunculus species and cultivars, all beautifully photographed by Georgianna Lane in their technicolour glory from palest pink to deep burgundy via white, orange, red and yellow. Pert as a rosebud and blousy as a dahlia, Ranunculus asiaticus is the flower of the moment. From ancestors that grew wild in the eastern Mediterranean, these Persian buttercups have been bred and selected to create fully double blooms; with layers of delicate, tissue-paper petals sculpted to perfection and available in a range of colours to suit any occasion. The buttercup family is a huge and diverse one, however, and the genus Ranunculus contains not just these exotic florists' darlings, but a whole range of their close relatives too. Some are familiar: when fields and lawns are sprinkled with golden meadow buttercups, we can be sure that spring has arrived. Yet there are also rare mountain blooms, perched on crags and fed by the melting snow, and forms of Ranunculus that thrive in pond margins or flourish in fast-flowing streams. Naomi Slade explores the world of buttercups, from their wild origins to their most successfully cultivated and most popular forms. Some are easy to grow, some less so, and this book offers tips and advice to help the reader embrace not just those near-wild forms that lend themselves to naturalistic planting schemes, and the exquisite, collectible alpines, but also the brilliant, desirable, Persian buttercups that are so perfect for cutting and arranging.

About seventy-one per cent of the Earth's surface is water, and even on dry land we remain closely connected to aquatic life. It provides us with oxygen, food, medicine and materials. Wild waterlife infiltrates our lives in many surprising ways. Every other breath we take is filled with oxygen provided by ocean-dwelling microscopic plants. A type of seaweed provides a means to directly test whether people are infected with viruses, including Covid-19. Robotics design takes inspiration from a pike's ability to accelerate with greater g-force than a Porsche. Wild Waters by Susanne Masters is a celebration of the breadth of wildlife that can be found in and around our varied waterways, from oceans and rivers to rock pools and ponds. Armchair explorers can read a fascinating account of how aquatic plants and animals enrich human life. Swimmers, paddleboarders, dog walkers, families and anyone with a passion for the great outdoors can learn about local wildlife, including when and where to look for different species without causing any harm. With stunning illustrations by Alice Goodridge, Wild Waters provides a tantalising insight into the world beneath the surface.
Say 'algae' and most people think of pond scum. What they don't know is that without algae, none of us would exist.; There are as many algae on earth as stars in the universe, and they have been essential to life on our planet for aeons. Algae created our oxygen-rich atmosphere, abundant oceans and coral reefs. Crude oil is made of dead algae, and algae are the ancestors of all plants.; Today, seaweed production is a multi-billion-dollar industry, with algae hard at work to make your sushi, beer, paint, toothpaste, shampoo and so much more. Delving into science and history, in this revelatory book Ruth Kassinger takes readers on an around-the-world, behind-the-scenes, and into-the-kitchen tour. We'll meet the algae innovators working towards a sustainable future: from seaweed farmers in South Korea, to scientists using it to clean the dead zones in our waterways, to the entrepreneurs fighting to bring algae fuel and plastics to market.; Bloom will overturn everything you thought you knew about algae and the immense power that they hold. This could be the future of our rapidly changing world.
This three-book set is devoted to the prominent bays of the Western North America. The first volume describes San Francisco Bay - a shallow estuary surrounded by a large population center. The forces that built it began with plate tectonics and involved the collision of the Pacific and North American plates and the subduction of the Juan de Fuka plate. Gold mining during the California gold rush sent masses of slit into the Bay. The second volume is devoted to San Diego Bay, which is also a shallow estuary surrounded by a large human population center that influenced the Bay. The third volume describes Puget Sound - a different sort of bay - a complex fjord-estuary system, but also surrounded by several large population centers. The watershed is enormous, covering nearly 43,000 square kilometers with thousands of rivers and streams. Geological forces, volcanos, Ice Ages, and changes in sea levels make the Sound a biologically dynamic and fascinating environment, as well as a productive ecosystem. Key Features Summarizes a complex geological, geographical, and ecological history Reviews how the San Diego Bay has changed and will likely change in the future Examines the different roles of various drivers of Bay ecosystem function Includes the role of humans-both first people and modern populations-on the Bay Explores San Diego Bay as an example of general bay ecological and environmental issues

The threat of climate displacement looms large over a growing number of countries. Based on the more than six years of work by Displacement Solutions in ten climate-affected countries, academic work on displacement and climate adaptation, and the country-level efforts of civil society groups in several frontline countries, this report explores the key contention that land will be at the core of any major strategy aimed at preventing and resolving climate displacement. This innovative and timely volume coordinated and edited by the Founder of Displacement Solutions, Scott Leckie, examines a range of legal, policy and practical issues relating to the role of land in actively addressing the displacement consequences of climate change. It reveals the inevitable truth that climate displacement is already underway and being tackled in countries such as Bangladesh, Kiribati, Papua New Guinea, Solomon Islands, Tuvalu and the United States, and proposes a series of possible land solution tools that can be employed to protect the rights of people and communities everywhere should they be forced to flee the places they call home.
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.

Southern Africa has a rich variety of tree species, with an estimated 2 100 indigenous species and more than 100 naturalised aliens. Field Guide to Trees of Southern Africa describes and illustrates more than 1 000 of these, focusing on trees that are the most common and most likely to be encountered. Species are logically arranged in 43 groups based on easy-to-observe leaf and stem features, and each account is illustrated by full-colour photographs of the plant’s diagnostic parts. The text also touches on the practical uses of the plants.
Gavin Hardy and Laurence Totelin have brought together their botanical and historical knowledge to produce this unique overview of ancient botany. It examines all the founding texts of botanical science, such as Theophrastus' Enquiry into Plants, Dioscorides' Materia Medica, Pliny the Elder's Natural History, Nicolaus of Damascus' On Plants, and Galen' On Simple Remedies, but also includes lesser known texts ranging from the sixth century BCE to the seventh century CE, as well as some material evidence. The authors adopt a thematic approach rather than a chronological one, considering important issues such as the definition of a plant, nomenclature, classifications, physiology, the link between plants and their environment, and the numerous usages of plants in the ancient world. The book also takes care to place ancient botany in its historical, social and economic context. The authors have explained all technical botanical terms and ancient history notions, and as a result, this work will appeal to historians of ancient science, medicine and technology; classicists; and botanists interested in the history of their discipline.

Forest Microbiology: Tree Diseases and Pests, Volume Three in the Forest Microbiology series, provides an overview of major disease agents of trees, including viruses, phytoplasma, bacteria, fungi, nematodes and major insect pests. With a strong emphasis on genetics, biochemistry, physiology, evolutionary biology and population dynamics of the organisms involved, this book provides a comprehensive understanding on the health of forests. Sections cover important pest threats such as bark beetles, emerald ash borer, coffee borers, leaf cutting ants, cocoa mirids, and more. This volume highlights a range of emerging diseases of forest trees in temperate and tropic regions as well as information on habitats. Forest trees play crucial roles not only for mitigating effects of the climate change but also for their considerable economic and ecological value. Forest trees are equally vital as an alternative bioenergy source and play important roles in pollution abatement and the maintenance of biodiversity. Timber and its associated products from forest trees contribute substantially to the revenue generation of many countries of the world.
The Sunday Times Bestseller A new, fully updated narrative edition of David Attenborough's seminal biography of our world, The Living Planet. Nowhere on our planet is devoid of life. Plants and animals thrive or survive within every extreme of climate and habitat that it offers. Single species, and often whole communities adapt to make the most of ice cap and tundra, forest and plain, desert, ocean and volcano. These adaptations can be truly extraordinary: fish that walk or lay eggs on leaves in mid-air; snakes that fly; flightless birds that graze like deer; and bears that grow hair on the soles of their feet. In The Living Planet, David Attenborough's searching eye, unfailing curiosity and infectious enthusiasm explain and illuminate the intricate lives of the these colonies, from the lonely heights of the Himalayas to the wild creatures that have established themselves in the most recent of environments, the city. By the end of this book it is difficult to say which is the more astonishing - the ingenuity with which individual species contrive a living, or the complexity of their interdependence on each other and on the habitations provided by our planet. In this new edition, the author, with the help of zoologist Matthew Cobb, has added all the most up-to-date discoveries of ecology and biology, as well as a full-colour 64-page photography section. He also addresses the urgent issues facing our living planet: climate change, pollution and mass extinction of species.
