This book highlights key results and lessons learnt from two field sites, La Suerte in Costa Rica and Ometepe Nicaragua. It provides long term data on species abundance and distribution. Primates receive specific attention in this book, as they are flagship species and good indicators for the "health" of an ecosystem, but as well a money maker. Many primate species are sensitive to habitat alteration, and are often hunted out first. But they play an important role as seed dispersal agents for the regeneration of the forest. The book then compares results from the two field sites with regional trends, and explores potential solutions such as REDD+. This book strongly calls for new approaches in conservation, it makes the case for looking beyond the pure species biology and classic conservation angle and to take into account the economic and political realities.

Beginning systematically with the fundamentals, the fully-updated third edition of this popular graduate textbook provides an understanding of all the essential elements of marine optics. It explains the key role of light as a major factor in determining the operation and biological composition of aquatic ecosystems, and its scope ranges from the physics of light transmission within water, through the biochemistry and physiology of aquatic photosynthesis, to the ecological relationships that depend on the underwater light climate. This book also provides a valuable introduction to the remote sensing of the ocean from space, which is now recognized to be of great environmental significance due to its direct relevance to global warming. An important resource for graduate courses on marine optics, aquatic photosynthesis, or ocean remote sensing; and for aquatic scientists, both oceanographers and limnologists.

An up-to-date, comprehensive and brilliantly illustrated book on fungi foraging in Britain and Europe. It covers every known edible species, and all the poisonous groups, as well as a few very common species and a handful of mushrooms included for their interesting or unusual characteristics. Identify edible and poisonous mushrooms. Distinguish between 'lookalike' species. Know when is the best time and place to hunt for each species. Identify edible species which should be left alone because they are threatened Photos show each species in its natural habitat, to aid identification. Perfect for all ability levels - from absolute beginner to the experienced fungi forager who'd like to become an expert. Each edible species is ranked according to its difficulty/danger level, so beginners can start with the easiest ones, while experienced foragers can learn how to safely forage for the trickier species that other mushroom foraging guides leave out.

Carnivorous plants have fascinated botanists, evolutionary biologists, ecologists, physiologists, developmental biologists, anatomists, horticulturalists, and the general public for centuries. Charles Darwin was the first scientist to demonstrate experimentally that some plants could actually attract, kill, digest, and absorb nutrients from insect prey; his book Insectivorous Plants (1875) remains a widely-cited classic. Since then, many movies and plays, short stories, novels, coffee-table picture books, and popular books on the cultivation of carnivorous plants have been produced. However, all of these widely read products depend on accurate scientific information, and most of them have repeated and recycled data from just three comprehensive, but now long out of date, scientific monographs. The field has evolved and changed dramatically in the nearly 30 years since the last of these books was published, and thousands of scientific papers on carnivorous plants have appeared in the academic journal literature. In response, Ellison and Adamec have assembled the world's leading experts to provide a truly modern synthesis. They examine every aspect of physiology, biochemistry, genomics, ecology, and evolution of these remarkable plants, culminating in a description of the serious threats they now face from over-collection, poaching, habitat loss, and climatic change which directly threaten their habitats and continued persistence in them.

Over the course of evolution, several plant lineages have found ways to obtain water, minerals, and carbohydrates from fungi. Some plants are able exploit fungi to such an extent that they lose the need for photosynthesis. The ability of a plant to live on fungal carbon is known as mycoheterotrophy. This intriguing process has fascinated botanists for centuries, yet many aspects of mycoheterotrophy have remained elusive for a long time. Mycoheterotrophy: The Biology of Plants Living on Fungi explores the biology of mycoheterotrophs, offering general insights into their ecology, diversity, and evolution. Written by renowned experts in the field and bolstered with lavish illustrations and photographs, this volume provides a thematic overview of different aspects of mycoheterotrophy. Comprehensive and readily accessible, Mycoheterotrophy: The Biology of Plants Living on Fungi is a valuable resource for researchers and students who are interested in the process of mycoheterotrophy.

Thorp and Covich's Freshwater Invertebrates, Volume 5: Keys to Neotropical and Antarctic Fauna, Fourth Edition, covers inland water invertebrates of the world. It began with Ecology and General Biology, Volume One (Thorp and Rogers, editors, 2015) and was followed by three volumes emphasizing taxonomic keys to general invertebrates of the Nearctic (2016), neotropical hexapods (2018), and general invertebrates of the Palearctic (2019). All volumes are designed for multiple uses and levels of expertise by professionals in universities, government agencies, private companies, and graduate and undergraduate students.

Sex in animals has been known for at least ten thousand years, and this knowledge was put to good use during animal domestication in the Neolithic period. In stark contrast, sex in plants wasn't discovered until the late 17th century, long after the domestication of crop plants. Even after its discovery, the "sexual theory" continued to be hotly debated and lampooned for another 150 years, pitting the "sexualists" against the "asexualists". Why was the notion of sex in plants so contentious for so long? "Flora Unveiled" is a deep history of perceptions about plant gender and sexuality, beginning in the Ice Age and ending in the middle of the nineteenth century, with the elucidation of the complete plant life cycle. Linc and Lee Taiz show that a gender bias that plants are unisexual and female (a "one-sex model") prevented the discovery of plant sex and delayed its acceptance long after the theory was definitively proven. The book explores the various sources of this gender bias, beginning with women's role as gatherers, crop domesticators, and the first farmers. In the myths and religions of the Bronze and Iron Ages, female deities were strongly identified with flowers, trees, and agricultural abundance, and during Middle Ages and Renaissance, this tradition was assimilated into Christianity in the person of Mary. The one-sex model of plants continued into the Early Modern Period, and experienced a resurgence during the eighteenth century Enlightenment and again in the nineteenth century Romantic movement. Not until Wilhelm Hofmeister demonstrated the universality of sex in the plant kingdom was the controversy over plant sex finally laid to rest. Although "Flora Unveiled" focuses on the discovery of sex in plants, the history serves as a cautionary tale of how strongly and persistently cultural biases can impede the discovery and delay the acceptance of scientific advances.

A collection of studies on the ecologies of European cities, including Paris, Zurich, and Amsterdam among others. Discussion includes the natural and historical development of each city, local flora, the environmental impact of city growth, and environmental planning, design, and management.

Asian tropical forests are amongst the most diverse on the planet, a richness that belies the fact that they are dominated by a single family of trees, the Dipterocarpaceae. Many other families contribute to Asia's natural diversity, but few compare to the dipterocarps in terms of the number and variety of species that occupy the forest canopy. Understanding the ecology and dynamics of Asian forests is therefore, to a large extent, a study of the Dipterocarpaceae. This book synthesises our current knowledge concerning dipterocarps, exploring the family through taxonomic, evolutionary, and biogeographic perspectives. Dipterocarp Biology, Ecology, and Conservation describes the rich variety of dipterocarp forest formations in both the ever-wet and seasonal tropics, including the less well known African and South American species. Detailed coverage of dipterocarp reproductive ecology and population genetics reflects the considerable research devoted to this subject, and its particular importance in shaping the ecology of Asian lowland rain forests. Ecophysiological responses to light, water, and nutrients, which underlie mechanisms that maintain dipterocarp species richness, are also addressed. At broader scales, dipterocarp responses to variation in soil, topography, climate, and natural disturbance regimes are explored from both population and community perspectives. The book concludes with a consideration of the crucial economic values of dipterocarps, and their extensive exploitation, discussing future opportunities for conservation and restoration. This will be a useful resource for senior undergraduate and graduate courses in tropical forest ecology and management, as well as professional researchers in tropical plant ecology, forestry, geography, and conservation biology.

In the race to feed the world's seven billion people, we are at a standstill. Over the past century, we have developed increasingly potent and sophisticated pesticides, yet in 2014, the average percentage of U.S. crops lost to agricultural pests was no less than in 1944. To use a metaphor the field of evolutionary biology borrowed from "Alice in Wonderland," farmers must run ever faster to stay in the same place--i.e., produce the same yields.
With "Chasing the Red Queen," Andy Dyer offers the first book to apply the Red Queen Hypothesis to agriculture. He illustrates that when selection pressure increases, species evolve in response, creating a never-ending, perpetually-escalating competition between predator (us) and prey (bugs and weeds). The result is farmers are caught in a vicious cycle of chemical dependence, stuck using increasingly dangerous and expensive toxics to beat back progressively resistant pests.
To break the cycle, we must learn the science behind it. Dyer examines one of the world's most pressing problems as a biological case study. He presents key concepts, from Darwin's principles of natural selection to genetic variation and adaptive phenotypes. Understanding the fundamentals of ecology and biology is the first step to "playing the Red Queen," and escaping her unwinnable race. The book's novel frame will help students, researchers, and policy-makers alike apply that knowledge to the critical task of achieving food security.

This book offers a concise but comprehensive introduction to desert ecology and adopts a strong evolutionary focus. As with other titles in the Biology of Habitats Series, the emphasis in the book is on the organisms that dominate this harsh environment, although theoretical and experimental aspects are also discussed. In this updated second edition, there is a greater focus on the effects of climate change and some of its likely effects on deserts, seeing desertification as among the most serious results of climate change, leading ultimately to the increasing size of arid and semi-arid regions. The Biology of Deserts Second Edition includes a wide range of ecological and evolutionary issues including morphological and physiological adaptations of desert plants and animals, species interactions, the importance of predation and parasitism, food webs, biodiversity, and conservation. It features a balance of plant and animal (both invertebrate and vertebrate) examples, and also emphasizes topical applied issues such as desertification and invasive species. The book concludes by considering the positive aspects of desert conservation. This accessible textbook is intended for senior undergraduate and graduate students, as well as professional ecologists, conservation practitioners, and resource managers working in the field of desert ecology.

Typically, landscape ecologists use empirical observations to conduct research and devise solutions for applied problems in conservation and management. In some instances, they rely on advice and input of experienced professionals in both developing and applying knowledge. Given the wealth of expert knowledge and the risks of its informal and implicit applications in landscape ecology, it is necessary to formally recognize and characterize expert knowledge and bring rigor to methods for its applications. In this context, the broad goal of this book is to introduce the concept of expert knowledge and examine its role in landscape ecological applications. We plan to do so in three steps: First we introduce the topic to landscape ecologists, explore salient characteristics of experts and expert knowledge, and describe methods used in capturing and formalizing that knowledge. Second, we present examples of research in landscape ecology from a variety of ecosystems and geographic locations that formally incorporate expert knowledge. These case studies address a range of topics that will interest landscape ecologists and other resource management and conservation professionals including the specific roles of expert knowledge in developing, testing, parameterizing, and applying models; estimating the uncertainty in expert knowledge; developing methods of formalizing and incorporating expert knowledge; and using expert knowledge as competing models and a source of alternate hypotheses. Third, we synthesize the state of knowledge on this topic and critically examine the advantages and disadvantages of incorporating expert knowledge in landscape ecological applications. The disciplinary subject areas we address are broad and cover much of the scope of contemporary landscape ecology, including broad-scale forest management and conservation, quantifying forest disturbances and succession, conservation of habitats for a range of avian and mammal species, vulnerability and conservation of marine ecosystems, and the spread and impacts of invasive plants. This text incorporates the collective experience and knowledge of over 35 researchers in landscape ecology representing a diverse range of disciplinary subject areas and geographic locations. Through this text, we will catalyze further thought and investigations on expert knowledge among the target readership of researchers, practitioners, and graduate students in landscape ecology.

This work advocates the restoration of the North American tallgrass prairie, which is rapidly disappearing. Historical descriptions of prairie aesthetics are outlined. As we are experiencing a worldwide mixing of plant species, prairie restoration is particularly important. Plants alien to North America do not readily support insect populations, including all animal species higher on the food chain. Prairie restoration methods are described for amateurs, academics, and land managers. Some of the techniques described are growing crops for seed production, times of seed gathering for specific species, facile seed processing for amateurs, land preparation, segregation of seed into its preference for habitat, and required seed treatment for germination. Over 200 species are described that comprise the predominant species found in tallgrass prairie nature preserves, as well as degraded prairies. Some additional plants of especial interest are also described. The appendix tabulates all likely species found on prairies regardless of their scarcity. Safe fire management of prairies is described in detail. Finally, methods of controlling aggressive alien weeds by herbicides are detailed.

Most projects in Landscape Ecology, at some point, define a species-habitat association. These models are inherently spatial, dealing with landscapes and their configurations. Whether coding behavioral rules for dispersal of simulated organisms through simulated landscapes, or designing the sampling extent of field surveys and experiments in real landscapes, landscape ecologists must make assumptions about how organisms experience and utilize the landscape. These convenient working postulates allow modelers to project the model in time and space, yet rarely are they explicitly considered. The early years of landscape ecology necessarily focused on the evolution of effective data sources, metrics, and statistical approaches that could truly capture the spatial and temporal patterns and processes of interest. Now that these tools are well established, we reflect on the ecological theories that underpin the assumptions commonly made during species distribution modeling and mapping. This is crucial for applying models to questions of global sustainability. Due to the inherent use of GIS for much of this kind of research, and as several authors' research involves the production of multicolored map figures, there would be an 8-page color insert. Additional color figures could be made available through a digital archive, or by cost contributions of the chapter authors. Where applicable, would be relevant chapters' GIS data and model code available through a digital archive. The practice of data and code sharing is becoming standard in GIS studies, is an inherent method of this book, and will serve to add additional research value to the book for both academic and practitioner audiences.

Growth in the field of landscape ecology has included the development of methods and results that can be applied to an impressive range of environmental issues. This book addresses a broad spectrum of political, theoretical and applied aspects that often arise in the design and execution of landscape studies. The concepts of geographical scale and hierarchy arising within the confines of landscape ecology are examined, and a series of techniques are presented to address problems in spatial and temporal analysis. This book will provide the reader with a current perspective on this rapidly evolving science.

Harsh environments found around the world harbour unique organisms adapted to extreme ranges in climatic, edaphic, and other environmental variables. Whether they occur in extreme climates such as alpine summits or inland deserts, in habitats frequently disturbed by fire or floods, or on edaphic islands created by unique geologies or anthropogenic contamination, the adaptations demonstrated by organisms found in such environments shed light on basic and applied aspects of ecology and evolution. This volume brings together current research on plants, fungi and microbes from harsh environments to reveal underlying patterns and common themes of these especially challenging habitats. Topics include the role of bedrock geochemistry and soil evolutionary processes in generating extreme habitats; the biology, ecology, and evolution of non-vascular and vascular plants, lichens, herbivores and pathogens, mycorrhizal fungi, and other beneficial microbes found in extreme environments. Habitats discussed in the book include alpine and arctic settings, fire-prone Mediterranean climates, serpentine outcrops, gypsum soils, metal-rich mine tailings, and saline soils. In addition to summarizing current research, we highlight new tools and emerging techniques in high-throughput phenotyping, genomics, and phylogenetics that are being used to develop our understanding of evolution in harsh environments. We also emphasise results gained from classical ecological approaches which have allowed us to examine adaptation to and evolution in harsh environments. In addition to discussing basic research, we cover applied work focusing on the threats posed by climate change and other anthropogenic impacts as well as efforts to restore and protect extreme habitats and the unique organisms they harbour. Finally, we discuss the uses of plant species found in extreme environments for agriculture and biotechnology, including the relatively new fields of phytoremediation and phytomining. The work highlighted in this volume demonstrates what these species and their environments have taught us about ecological and evolutionary theory, conservation, and restoration: knowledge that can be applied well beyond the habitats and species described in this book.

This book presents the latest scientific and management information on multiaged silviculture, an emerging strategy for managing forestry systems worldwide. Over recent decades, forest science and management have tended to emphasize plantation silviculture. Whilst this clearly meets our wood production needs, many of the world's forests need to be managed far less intensively and more flexibly in order to maintain their natural ecosystem functions together with the values inherent in those processes. Developing multiaged management strategies for these complex forest ecosystems represents a global challenge to successfully integrate available science with sustainable management practices. Multiaged Silviculture covers the ecology and dynamics of multiaged stands, the management operations associated with regeneration, tending, and stocking control, and the implications of this strategy on production, genetic diversity, and stand health. It is primarily aimed at graduate level students and researchers in the fields of forestry and silviculture, but will also be of relevance and use to all professional foresters and silviculturists.

While the research and management of wildlife has traditionally emphasised studies at smaller scales, it is now acknowledged that larger, landscape-level patterns strongly influence demographic processes in wild animal species. This book is the first to provide the conceptual basis for learning how larger scale patterns and processes can influence the biology and management of wildlife species. It is divided into three sections: Underlying Concepts, Landscape Metrics and Applications and Large Scale Management.

Towns and villages are sometimes viewed as minor, even quaint, spots, whereas this book boldly reconceptualizes these places as important dynamic environmental 'hotspots'. Multitudes of towns and villages with nearly half the world's population characterize perhaps half the global land surface. The book's pages feature ecological patterns, processes, and change, as well as human dimensions, both within towns and in strong connections and effects on surrounding agricultural land, forest land, and arid land. Towns, small to large, and villages are examined with spatial and cultural lenses. Ecological dimensions - water, soil and air systems, together with habitats, plants, wildlife and biodiversity - are highlighted. A concluding section presents concepts for making better towns and better land. From a pioneer in both landscape ecology and urban ecology, this highly international town ecology book opens an important frontier for researchers, students, professors, and professionals including environmental, town, and conservation planners.

Marine and freshwater systems are being placed under pressure like never before. A bigger and more demanding human population has meant increased utilisation of aquatic systems and, as such, the need for sustainable solutions to allow the development and conservation of these systems has become an international priority. In order to understand the limits of exploitation, an understanding is needed of the ecological principles that constrain levels of productivity and the systems' responses to exploitation pressure. This timely book explores current exploitation practices, and the ecological basis and consequences of that exploitation. From a consideration of the ecological effects of the extraction of non-living resources, including energy and water itself, it progresses to the biology and ecology of aquatic organisms, and how these underpin the harvesting for aquatic resources. A discussion of the ecological consequences for the system of its use as a means of transport and as a repository for wastes follows, along with the increasing importance of aquatic systems for human recreational pursuits. Finally, effective management strategies for natural hazards, the provision of ecological goods and services, and restoration of aquatic systems are considered, as well as the importance of ecological science in exploitation management. The role of science in providing an understanding of the effects of human intervention in aquatic systems is emphasised throughout, along with a consideration of the role of ecology in the sustainable management of the consequences of human activity.

This handbook provides a general introduction to the National Vegetation Classification (NVC). It details the methodology for sampling and describing vegetation in the field, explains how such information can be used to identify plant communities and outlines the character of the classification itself and the accounts of vegetation types it contains. It also discusses the important issues involved in carrying out an NVC survey of a site and gives a brief indication of other applications of the scheme. This is a reprint edition of: ISBN 978-1-86107-574-1 (2006).

This book presents the state-of-the-art of knowledge in assessing, mapping, and modeling mangrove ecosystem services and outlines various scientific tools and techniques, including environmental scenario-building, spatial and econometric modelling to understand the fluctuations and future availability of mangrove ecosystem services. The book also highlights the current gaps and measures in policy planning and outlines the avenues for capacity building. Through case studies and thematic reviews, the book plans to cater to a wide range of audiences, including students, researchers, and decision-makers at various levels involved in mangrove conservation and land use optimization for sustainable and resilient development. This book is particularly useful to researchers and students in the field of landscape and spatial ecology, coastal zone management, ecosystem services, and resilience planning. It is also a must-read for policymakers, conservators, coastal zone managers, foresters, and general administrators in understanding the current and future roles of mangroves in ecosystem-based adaptation through informed decision-making.

Simply put, allelopathy refers to an ecological phenomenon of plant-plant interference through release of organic chemicals (allelochemicals) in the environment. These chemicals can be directly and continuously released by the donor plants in their immediate environment as volatiles in the air or root exudates in soil or they can be the microbial degradation products of plant residues. The chemicals may interfere with survival and growth of neighboring or succeeding plants. Black walnut, eucalyptus, sunflower, sorghum, sesame and alfalfa are common examples of plants with allelopathic property as well as some staple crops such as rice, wheat, barley and sorghum. Plants can emit chemicals that also discourage insects and pathogens. To maintain sustained productivity, knowledge of this form of plant interference on other plants and on disease causing organisms has been used in agriculture since prehistoric time by manipulating cropping pattern and sequence such as mixed cropping and crop rotation. However, use of numerous agrochemicals including a wide range of herbicides, pesticides, fertilizers and genetically modified high yielding crops has become the characteristic feature of modern industrial agriculture. Not only the sustainability of crop yield is called into question in this form of agriculture, the extensive long-term and often irreversible environmental degradation including ground water contamination and food safety associated with industrial agriculture are now of serious concern worldwide.

The objective is to report on the latest advances in allelopathy by inviting leading scientists to contribute in specific fields. The volume is organized under three major subsections: History of allelopathy, Allelochemicals, allelopathic mechanisms, and bioassays, and Application of allelopathy in agriculture and forestry. An emphasis is place on methodology and application, making it a truly practical reference.

Rain forests represent the world's richest repository of terrestrial biodiversity, and play a major role in regulating the global climate. They support the livelihoods of a substantial proportion of the world's population and are the source of many internationally traded commodities. They remain (despite decades of conservation attention) increasingly vulnerable to degradation and clearance, with profound though often uncertain future costs to global society. Understanding the ecology of these diverse biomes, and peoples' dependencies on them, is fundamental to their future management and conservation.
Tropical Rain Forest Ecology, Diversity, and Conservation introduces and explores what rain forests are, how they arose, what they contain, how they function, and how humans use and impact them. The book starts by introducing the variety of rain forest plants, fungi, microorganisms, and animals, emphasising the spectacular diversity that is the motivation for their conservation. The central chapters describe the origins of rain forest communities, the variety of rain forest formations, and their ecology and dynamics. The challenge of explaining the species richness of rain forest communities lies at the heart of ecological theory, and forms a common theme throughout. The book's final section considers historical and current interactions of humans and rain forests. It explores biodiversity conservation as well as livelihood security for the many communities that are dependent on rain forests - inextricable issues that represent urgent priorities for scientists, conservationists, and policy makers.
