What are the ecological attributes of weeds that confer the ability to interfere with human activities? Roger Cousens and Martin Mortimer place weed management within an ecological context, with the focus on the manipulation of population size. The dynamics of abundance and spatial distribution are considered at both geographic and local scales. The basic processes of dispersal, reproduction and mortality are described, together with the factors that influence them. Management is shown to modify patterns of behaviour that are intrinsic to populations. Attention is given to the evolution and management of resistance to herbicides. This book provides weed science with the conceptual basis that has previously been lacking. It also gives ecologists access to the extensive database on the population ecology of weeds.

A great many terrestrial plants live in close association with fungi. The features of this association known as mycorrhiza, are those of a mutualistic symbiosis. Almost all plants form mycorrhizae whereby the fungus provides soil resources to the plant in exchange for energy manufactured by the plant. The symbiosis means greater productivity under stress for the plant and a steady energy supply for the fungus. This book addresses the diverse and complex ways in which mycorrhizae affect the mechanisms for plant survival as individuals and populations, for community structure, and for ecosystem functioning. It integrates information on organisms interacting with mycorrhizae from bacteria to mammals. The author takes a unique evolutionary/ecological approach to describe how and under what conditions mycorrhizae influence basic ecological processes. The applications of mycorrhizal symbioses range from managing natural and agricultural lands to biotechnological processes that enhance agricultural productivity and sustainability.

There is a growing concern that many important ecosystems, such as coral reefs and tropical rain forests, might be at risk of sudden collapse as a result of human disturbance. At the same time, efforts to support the recovery of degraded ecosystems are increasing, through approaches such as ecological restoration and rewilding. Given the dependence of human livelihoods on the multiple benefits provided by ecosystems, there is an urgent need to understand the situations under which ecosystem collapse can occur, and how ecosystem recovery can best be supported. To help develop this understanding, this volume provides the first scientific account of the ecological mechanisms associated with the collapse of ecosystems and their subsequent recovery. After providing an overview of relevant theory, the text evaluates these ideas in the light of available empirical evidence, by profiling case studies drawn from both contemporary and prehistoric ecosystems. Implications for conservation policy and practice are then examined.

Correlation between plant distribution and climate is examined over different time and space scales to determine the mechanisms of control in physiological and biochemical terms.

The modern ecologist usually works in both the field and laboratory, uses statistics and computers, and often works with ecological concepts that are model-based, if not model-driven. How do we make the field and laboratory coherent? How do we link models and data? How do we use statistics to help experimentation? How do we integrate modeling and statistics? How do we confront multiple hypotheses with data and assign degrees of belief to different hypotheses? How do we deal with time series (in which data are linked from one measurement to the next) or put multiple sources of data into one inferential framework? These are the kinds of questions asked and answered by "The Ecological Detective."

Ray Hilborn and Marc Mangel investigate ecological data much as a detective would investigate a crime scene by trying different hypotheses until a coherent picture emerges. The book is not a set of pat statistical procedures but rather an approach. The Ecological Detective makes liberal use of computer programming for the generation of hypotheses, exploration of data, and the comparison of different models. The authors' attitude is one of exploration, both statistical and graphical. The background required is minimal, so that students with an undergraduate course in statistics and ecology can profitably add this work to their tool-kit for solving ecological problems.

Does biodiversity influence how ecosystems function? Might diversity loss affect the ability of ecosystems to deliver services of benefit to humankind? Ecosystems provide food, fuel, fiber, and drinkable water, regulate local and regional climate, and recycle needed nutrients, among other things. An ecosyste's ability to sustain functioning may depend on the number of species residing in the ecosystem--its biological diversity--but this has been a controversial hypothesis. There are many unanswered questions about how and why changes in biodiversity could alter ecosystem functioning. This volume, written by top researchers, synthesizes empirical studies on the relationship between biodiversity and ecosystem functioning and extends that knowledge using a novel and coordinated set of models and theoretical approaches.

These experimental and theoretical analyses demonstrate that functioning usually increases with biodiversity, but also reveals when and under what circumstances other relationships between biodiversity and ecosystem functioning might occur. It also accounts for apparent changes in diversity-functioning relationships that emerge over time in disturbed ecosystems, thereby addressing a major controversy in the field. The volume concludes with a blueprint for moving beyond small-scale studies to regional ones--a move of enormous significance for policy and conservation but one that will entail tackling some of the most fundamental challenges in ecology.

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.

In coastal seas, from the tropics to the poles, seaweeds supply the energy required to support diverse coastal marine life and provide habitat for invertebrates and fish. Retaining the highly successful approach and structure of the first edition, this is a synthesis of the role of seaweeds in underpinning the functioning of coastal ecosystems worldwide. It has been fully updated to cover the major developments of the past twenty years, including current research on the endosymbiotic origin of algae, molecular biology including 'omics', chemical ecology, invasive seaweeds, photobiology and stress physiology. In addition to exploring the processes by which seaweeds, as individuals and communities, interact with their biotic and abiotic environment, the book presents exciting new research on how seaweeds respond to local and global environmental change. It remains an invaluable resource for students and provides an entry into the scientific literature of a wide range of topics.

Ecology is capturing the popular imagination like never before, with issues such as climate change, species extinctions, and habitat destruction becoming ever more prominent. At the same time, the science of ecology has advanced dramatically, growing in mathematical and theoretical sophistication. Here, two leading experts present the fundamental quantitative principles of ecology in an accessible yet rigorous way, introducing students to the most basic of all ecological subjects, the structure and dynamics of populations.

John Vandermeer and Deborah Goldberg show that populations are more than simply collections of individuals. Complex variables such as distribution and territory for expanding groups come into play when mathematical models are applied. Vandermeer and Goldberg build these models from the ground up, from first principles, using a broad range of empirical examples, from animals and viruses to plants and humans. They address a host of exciting topics along the way, including age-structured populations, spatially distributed populations, and metapopulations.

This second edition of "Population Ecology" is fully updated and expanded, with additional exercises in virtually every chapter, making it the most up-to-date and comprehensive textbook of its kind.Provides an accessible mathematical foundation for the latest advances in ecologyFeatures numerous exercises and examples throughoutIntroduces students to the key literature in the fieldThe essential textbook for advanced undergraduates and graduate studentsAn online illustration package is available to professors

Researchers and advanced students in environmental sciences, plant ecophysiology, biochemistry, molecular biology, nano-pollution climate change, and soil pollution will find this an important foundational resource.

Ecophysiology of Pesticides: Interface between Pesticide Chemistry and Plant Physiology is the first comprehensive overview of the physical impact of this increasingly complex environmental challenge. Designed to offer state-of-the-art knowledge, the book covers pesticide usage and its consequences on the ecophysiology of plants. It includes the challenge of policymaking in pesticide consumption and a risk analysis of conventional and modern approaches on standard usage. In addition, it summarizes research reports pertaining to the physio-ecological effects of pesticides, discusses the environmental risks associated with the over-utilization of pesticides, and covers pesticide usage on the micro-flora and rhizosphere. This book is a valuable reference for plant ecologists, plant biochemists and chemists who want to study pesticide consumption and its biochemical and physiological evaluation effects on plants. It will also be of immense help to university and college teachers and students of environmental biotechnology, environmental botany and plant ecophysiology.

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.

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.

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.

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 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.

Allelopathy refers to the beneficial or harmful effects of one plant on another, including both crop and weed species. Mushrooms is one such example which provides various effects to their curcumjacent plants by releasing allelochemicals. The authors' of this book examine the allelopathy of mushrooms and showed that all mushrooms have allelopathic activity without exception. Furthermore, rice, barley, wheat, rye, sorghum and sunflower are known to be allelopathic crops. The authors focus on buckwheat in particular, to determine whether or not it is allelopathic as well. Other chapters examine the allelopathic effects of macrophytes in subtropical shallow lakes; and the invasive potential of parthenium weed, a herbaceous plant, and one that has now invaded over 44 countries worldwide, having an impact upon both crop and pasture production, natural community biodiversity and human and animal health.

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.

'A bold, ambitious and truly wonderful history of the world' Peter Wohlleben, author of The Hidden Life of Trees 'A fascinating story and a crucial revision of the momentous importance of tropical forests to human history' Lewis Dartnell, author of Origins _________________________ Jungle tells the remarkable story of the world's tropical forests, from the arrival of the first plants millions of years ago to the role of tropical forests in the evolution of the world's atmosphere, the dinosaurs, the first mammals and even our own species and ancestors. Highlighting provocative new evidence garnered from cutting-edge research, Dr Roberts shows, for example, that our view of humans as 'savannah specialists' is wildly wrong, and that the 'Anthropocene' began not with the Industrial Revolution, but potentially as early as 6,000 years ago in the tropics. We see that the relationship between humankind and 'jungles' is deep-rooted, that we are all connected to their destruction, and that we must all act to save them. Urgent, clear-sighted and original, Jungle challenges the way we think about the world - and ourselves. _________________________ 'Welcome to the "Jungle" - a breathtaking book' Mark Maslin, author of How to Save Our Planet 'Timely, readable and highly relevant' Steve Brusatte, author of The Rise and Fall of the Dinosaurs 'Its revelations and stories will stir, rearrange and populate your mind for years to come' Paul Hawken, editor of Drawdown 'Brilliant ... it delivers a timely warning about our abuse of the environment' David Abulafia, author of The Great Sea 'Finally, a book on rainforests that does justice to their majesty and importance' Simon Lewis, co-author of The Human Planet

Despite its small size, Belize is one of the most ecologically and culturally diverse nations in Central America. Over 3,400 species of plants can be found here, within a diversity of ecological habitats. Because of this, Belize is paradise for ecotourists, hosting over 900,000 visitors annually, who enjoy the natural habitat and friendly people of this nation. Many of the plants of Belize have a long history of being "useful," with properties that have served traditional herbal healers of the region as well as those who use plants as food, forage, fiber, ornament, in construction and ritual, along with many other purposes. With Messages from the Gods: A Guide to the Useful Plants of Belize, Drs. Michael Balick and Rosita Arvigo give us the definitive resource on the many species of plants in Belize and their folklore, as well as the natural history of the region and a detailed discussion of "bush" uses of plants, including for traditional healing and life in the forest, past and present. Both Balick and Arvigo bring important perspectives to the project, Balick as ethnobotanical scientist from The New York Botanical Garden, and Arvigo as a former apprentice to a Belizean healer and an experienced physician. The book has been decades in the making, a culmination of a biodiversity research project that The New York Botanical Garden and international and local collaborators have had in motion since 1987. Drs. Balick, Arvigo and their colleagues have collected and identified thousands of plants from the region, and have worked extensively with hundreds of Belizean people, many of them herbal healers and bushmasters, to record uses for many of the species. This collaboration with local plant experts has produced a fascinating discussion of the intersection of herbal medicine and spiritual belief in the area, and these interviews are used to compliment and contextualize the numerous species accounts presented. The book is both a cultural study and a specialized field guide; information is provided on many different native and introduced plants in Belize and their traditional and contemporary uses including as food, medicine, fiber, in spiritual practices and many other purposes. Richly illustrated with over 600 images and photographs, Messages from the Gods: A Guide to The Useful Plants of Belize will serve as the primary reference and guide to the ethnobotany of Belize for many years to come.
