There has been a recent surge of interest in remote sensing and its use in ecology and conservation but this is the first book to focus explicitly on the NDVI (Normalised Difference Vegetation Index), a simple numerical indicator and powerful tool that can be used to assess spatio-temporal changes in green vegetation. The NDVI opens the possibility of addressing questions on scales inaccessible to ground-based methods alone; it is mostly freely available with global coverage over several decades. This novel text provides an authoritative overview of the principles and possible applications of the NDVI in ecology, environmental and wildlife management, and conservation. NDVI data can provide valuable information about temporal and spatial changes in vegetation distribution, productivity, and dynamics; allowing monitoring of habitat degradation and fragmentation, or assessment of the ecological effects of climatic disasters such as drought or fire. The NDVI has also provided ecologists with a promising way to couple vegetation with animal distribution, abundance, movement, survival and reproductive parameters. Over the last few decades, numerous studies have highlighted the potential key role of satellite data and the NDVI in macroecology, plant ecology, animal population dynamics, environmental monitoring, habitat selection and habitat use studies, and paleoecology. The chapters are organised around two sections: the first detailing vegetation indices and the NDVI, the principles behind the NDVI, its correlation with climate, the available NDVI datasets, and the possible complications and errors associated with the use of this satellite-based vegetation index. The second section discusses the possible applications of the NDVI in ecology, environmental and wildlife management, and conservation. This practical handbook is suitable for terrestrial ecologists and conservation biologists working with remote sensing tools. It will also be of relevance and use to both graduate students in the biological and ecological sciences and specialists in the fields of conservation biology, biodiversity monitoring, and natural resource management.
One of the most interesting and vexing problems in ecology is how
distinctly different communities of plants and animals can occur in
the same ecosystem. The theory of these systems, known as multiple
stable states, is well understood, but whether multiple stable
states actually exist in nature has remained a hotly debated
subject.
This book addresses an important problem in ecology: how are communities assembled from species pools? This pressing question underlies a broad array of practical problems in ecology and environmental science, including restoration of damaged landscapes, management of protected areas, and protection of threatened species. This book presents a simple logical structure for ecological assembly and addresses key areas including species pools, traits, environmental filters, and functional groups. It demonstrates the use of two predictive models (CATS and Traitspace) and consists of many wide-ranging examples including plants in deserts, wetlands, and forests, and communities of fish, amphibians, birds, mammals, and fungi. Global in scope, this volume ranges from the arid lands of North Africa, to forests in the Himalayas, to Amazonian floodplains. There is a strong focus on applications, particularly the twin challenges of conserving biodiversity and understanding community responses to climate change.
The origin of biological diversity, via the formation of new species, can be inextricably linked to adaptation to the ecological environment. Specifically, ecological processes are central to the formation of new species when barriers to gene flow (reproductive isolation) evolve between populations as a result of ecologically-based divergent natural selection. This process of 'ecological speciation' has seen a large body of particularly focused research in the last 10-15 years, and a review and synthesis of the theoretical and empirical literature is now timely. The book begins by clarifying what ecological speciation is, its alternatives, and the predictions that can be used to test for it. It then reviews the three components of ecological speciation and discusses the geography and genomic basis of the process. A final chapter highlights future research directions, describing the approaches and experiments which might be used to conduct that future work. The ecological and genetic literature is integrated throughout the text with the goal of shedding new insight into the speciation process, particularly when the empirical data is then further integrated with theory.

In recent years it has become increasingly clear that chemical interactions play a fundamental role in aquatic habitats and have far-reaching evolutionary and ecological consequences. A plethora of studies have shown that aquatic organisms from most taxa and functional groups respond to minute concentrations of chemical substances released by other organisms. However, our knowledge of this "chemical network" is still negligible. Chemical interactions can be divided into two larger sub-areas based on the function of the chemical substance. First, there are interactions where chemical substances are toxic to other organisms and are used as a defence against consumers (including both herbivores and predators) or a weapon against competitors (allelopathy). Second, chemical substances may be used as a source for information of the environment; for example: how can I find the optimal habitat, the best food, the nicest partner, and avoid being eaten? Aquatic organisms are able to detect and respond to extremely low concentrations of chemical cues to answer all these questions. The book aims at connecting these intriguing chemical interactions with traditional knowledge of organism interactions. Chemical Ecology of Aquatic Systems covers a wide range of studies, both plant and animal, from different geographic regions and habitats - pelagic as well as benthic. Most of the chemical interactions are similar in freshwater and marine habitats and this book therefore strives at integrating work on both systems.
Global wetlands exhibit significant differences in both hydrology
and species composition and range from moss-dominated arctic
peatlands to seasonally-flooded tropical floodplains. They are
increasingly recognized for the important services that they
provide to both the environment and human society such as wildlife
and fish production, nutrient filtering, and carbon sequestration.
This book provides the first global synthesis of the biology of disturbed habitats and offers readers both the conceptual underpinnings and practical advice required to comprehend and address the unprecedented environmental challenges facing humans. Every habitat on earth has been impacted by natural disturbances such as volcanoes, earthquakes, landslides, fires, floods, and droughts. Humans have contributed many additional disturbances such as mining, urbanization, forestry, agriculture, fishing, and recreation. These anthropogenic disturbances modify and often exacerbate the effects of the natural disturbances. Together, they result in the abrupt loss of biomass or ecosystem structure and function to create denuded surfaces where novel mixtures of native and non-native microbes, plants, and animals establish, grow, and die. The Biology of Disturbed Habitats examines both natural and anthropogenic disturbances in aquatic and terrestrial habitats. It explores how nutrients and productivity are altered in the disturbed habitats, the effects of disturbance on biodiversity, and the spatial and temporal dynamics of organisms that colonize disturbed habitats. This book also addresses how to manage disturbances through appropriate conservation and restoration measures, and discusses how climate change and overpopulation now represent the most challenging disturbances at a global scale.
The genomics revolution has expanded from its origins in molecular biology to impact upon every discipline in the life sciences, including ecology. Several lines of ecological research can now be profitably addressed using genomics technology, including issues of nutrient cycling, population structure, life-history variation, trophic interaction, stress responses, and adaptation to environmental change. This new edition addresses a series of fundamental ecological questions: the relationship between community structure and ecological function in ecosystems; how variation in life-history patterns among species can be explained from interaction between the genome and the environment; the molecular responses to changing and toxic environmental conditions; adaptive phenotypes and their relationship to genetic variation. Each of these questions is evaluated in the light of recent advances in genomics research, paying particular attention to data obtained from sequencing and screening of environmental genomes (metagenomics), microarray-based transcription profiling, gene expression directed by signal-transduction pathways, and the analysis of genomic polymorphisms. The chapters covering these key areas are preceded by discussions of genomics methodology (including an overview of next-generation sequencing technologies) and comparative genomics, and the book concludes with a chapter on integrative approaches such as ecological control analysis. The authors also provide a comparative survey of the properties of genomes (genome size, gene families, synteny, and polymorphism) for prokaryotes as well as the main eukaryotic models. An Introduction to Ecological Genomics incorporates a balance of plant, animal, and microbial examples, and continues to define the new and exciting field of ecological genomics.
Communication is an essential factor underpinning the interactions
between species and the structure of their communities.
Plant-animal interactions are particularly diverse due to the
complex nature of their mutualistic and antagonistic relationships.
However the evolution of communication and the underlying
mechanisms responsible remain poorly understood.
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.
Theoretical Ecology: concepts and applications continues the authoritative and established sequence of theoretical ecology books initiated by Robert M. May which helped pave the way for ecology to become a more robust theoretical science, encouraging the modern biologist to better understand the mathematics behind their theories. This latest instalment builds on the legacy of its predecessors with a completely new set of contributions. Rather than placing emphasis on the historical ideas in theoretical ecology, the Editors have encouraged each contribution to: synthesize historical theoretical ideas within modern frameworks that have emerged in the last 10-20 years (e.g. bridging population interactions to whole food webs); describe novel theory that has emerged in the last 20 years from historical empirical areas (e.g. macro-ecology); and finally to cover the rapidly expanding area of theoretical ecological applications (e.g. disease theory and global change theory). The result is a forward-looking synthesis that will help guide the field through a further decade of discovery and development. It is written for upper level undergraduate students, graduate students, and researchers seeking synthesis and the state of the art in growing areas of interest in theoretical ecology, genetics, evolutionary ecology, and mathematical biology.
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.
Bioinvasions and Globalization synthesises our current knowledge of
the ecology and economics of biological invasions, providing an
in-depth evaluation of the science and its implications for
managing the causes and consequences of one of the most pressing
environmental issues facing humanity today.
Community ecology is the study of the interactions between
populations of co-existing species. Co-edited by two prominent
community ecologists and featuring contributions from top
researchers in the field, this book provides a survey of the
state-of-the-art in both the theory and applications of the
discipline. It pays special attention to topology, dynamics, and
the importance of spatial and temporal scale while also looking at
applications to emerging problems in human-dominated ecosystems
(including the restoration and reconstruction of viable
communities).
Mycorrhizal symbioses are widespread and fundamental components of terrestrial ecosystems and have shaped plant evolution. Research in this field is rapidly evolving and recent findings have done much to improve our understanding of how these complex plant/fungal associations function. This volume, which is aimed at the scientific community, comprises 14 chapters written by more than 30 international experts for different fields of mycorrhizal research. The chapters provide either in-depth reviews or the results of previously unpublished scientific studies, and certain are illustrated with photos and line drawings. The topics covered are of global interest and include plant-fungal communication, the interaction of mycorrhizal fungi and other soil microorganisms, the use of mycorrhizal fungi in plant-production systems, and the commercial harvesting of edible mycorrhizal forest mushrooms.
How will biodiversity loss affect ecosystem functioning, ecosystem
services, and human well-being?

Grasslands, in particular managed pastures and rangelands, are
widespread, covering approximately 40% (52 million km2) of the
Earth's land surface. They are dominated by members of the Poaceae
- the fourth largest plant family with over 7,500 species, and also
the most widespread. Grasslands constitute a major biome on all
continents except Antarctica and also represent the most important
food crop on Earth with corn, wheat, maize, rice and millet
accounting for the majority of our agricultural output.
This advanced textbook is the first to explore the consequences of plant dispersal for population and community dynamics, spatial patterns, and evolution. It successfully integrates a rapidly expanding body of theoretical and empirical research. The first comprehensive treatment of plant dispersal set within a population framework Examines both the processes and consequence of dispersal Spans the entire range of research, from natural history and collection of empirical data to modeling and evolutionary theory Provides a clear and simple explanation of mathematical concepts Dispersal in Plants is aimed principally at graduates interested in plant ecology, although given the strong current interests in invasive species and global change it will also be of interest and use to a broad audience of plant scientists and ecologists seeking an authoritative overview of this rapidly expanding field.
Robert May's seminal book has played a central role in the
development of ecological science. Originally published in 1976,
this influential text has overseen the transition of ecology from
an observational and descriptive subject to one with a solid
conceptual core. Indeed, it is a testament to its influence that a
great deal of the novel material presented in the earlier editions
has now been incorporated into standard undergraduate textbooks. It
is now a quarter of a century since the publication of the second
edition, and a thorough revision is timely.
The reproductive organs and mating biology of angiosperms exhibit
greater variety than those of any other group of organisms. Flowers
and inflorescences are also the most diverse structures produced by
angiosperms, and floral traits provide some of the most compelling
examples of evolution by natural selection. Given that flowering
plants include roughly 250,000 species, their reproductive
diversity will not be explained easily by continued accumulation of
case studies of individual species. Instead a more strategic
approach is now required, which seeks to identify general
principles concerning the role of ecological function in the
evolution of reproductive diversity.
Why are some kinds of organism species-rich and others species-poor? How do new species arise and why do some go extinct? Why do organisms grow and behave the way they do? This book provides an introduction to evolutionary ecology, the science that brings ecology and evolution together to help understand biological diversity. In a concise, readable format, Peter Mayhew covers the entire breadth of the subject, from life histories and the evolution of sex, to speciation and macroecology. Many emerging fields are also introduced, such as metabolic ecology, the evolution of population dynamics, and the evolution of global ecology. Discovering Evolutionary Ecology highlights the connections between these different subject areas, and for the first time paints a picture of a truly integrated field. It illustrates the research tools utilized, and demonstrates how advances in one area can spur on developments elsewhere when scientists combine evolutionary and ecological knowledge. To maximize accessibility, the book assumes only a basic knowledge of biology, includes a comprehensive glossary, and contains almost no maths. Each chapter provides suggestions for further reading, and there is also an extensive reference list. Ideal as an introduction to evolutionary ecology for undergraduates, this book will also interest established researchers, providing a broad and up-to-date context for their work.
Tropical forests represent the world's most biodiverse ecosystems and play a key role in hydrology, carbon storage and exchange. Many of the human-induced pressures these regions are facing, e.g. fragmentation and deforestation, have been widely reported and well documented. However, there have been surprisingly few efforts to synthesize cutting-edge science in the area of tropical forest interaction with atmospheric change. At a time when our global atmosphere is undergoing a period of rapid change, both in terms of climate and in the cycling of essential elements such as carbon and nitrogen, a thorough and up-to-date analysis is now timely. This research level text, suitable for graduate level students as well as professional researchers in plant ecology, tropical forestry, climate change science, and conservation biology, explores the vigorous contemporary debate as to how rapidly tropical forests may be affected by atmospheric change, and what this may mean for their future. |
