Aquatic insects are the dominant invertebrate fauna in most freshwater ecosystems, and figure prominently in the work of a diverse range of researchers, students, and environmental managers. Often employed as indicators of ecosystem health, aquatic insects are also commonly used as model systems to test hypotheses in ecological topics including metapopulation and metacommunity dynamics, recruitment limitation, trophic interactions, and trophic networks. Due to their complex life cycles, aquatic insects must master both terrestrial and aquatic environments, crossing these ecosystem boundaries during different stages of development and reproduction. In this wide-ranging text, life under and on top of the water surface are covered in unusual detail, including the biomechanics of life in water, locomotion underwater and on surface films, gas exchange, physico-chemical stressors, feeding, sensory perception and communication, reproduction, egg-laying and development, and the evolution of aquatic habits. The threatened status of freshwaters around the world, coupled with an expanding population of researchers and managers charged with their well-being, signals the importance of such a book as many individuals seek to understand how insects function in these often challenging physical environments. Interest in freshwaters may never have been higher with ever-increasing conflict between water allocation for human (agricultural) use and conservation. Aquatic Entomology is suitable for graduate students, researchers, and managers interested in the subject from a perspective of either basic or applied ecology. It will also be a valuable supplementary text for courses in limnology or freshwater ecology, entomology, and water resource management.

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.
Marine Biodiversity and Ecosystem Functioning is the first book to address the latest advances in biodiversity-function science using marine examples. It brings together contributions from the leading scientists in the field to provide an in-depth evaluation of the science, before offering a perspective on future research directions for some of the most pressing environmental issues facing society today and in the future.

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.
A combination of low oxygen levels and dense plant canopies present particular challenges for organisms living in this aquatic habitat. This concise textbook discusses the universal environmental and biological features of wetland habitats, with an emphasis on wetland plants and animals and their adaptations. It also describes the functional features of wetlands - primary production, litter decomposition, food webs, and nutrient cycling - and their significance locally and globally. The future of wetlands is examined, including the potential threats of global climate change and invasive species, as well as their restoration and creation.
This new edition maintains the structure and style of the first, but is fully updated throughout with new chapters on invasive species, restoration/creation, global climate change, and the value of wetlands.

Snow and ice environments support significant biological activity, yet the biological importance of some of these habitats, such as glaciers, has only recently gained appreciation. Collectively, these ecosystems form a significant part of the cryosphere, most of which is situated at high latitudes. These ice environments are important sentinels of climate change since the polar regions are presently undergoing the highest rates of climate warming, resulting in very marked changes in the extent of ice caps, glaciers, and the sea ice. Glacial systems are also regarded as an analogue for astrobiology, particularly for Mars and the moons of Jupiter (e.g. Europa), and one of the justifications for research in this area is its potential value in astrobiology. This timely and accessible volume draws together the current knowledge on life in snow and ice environments. It describes these often complex and often productive ecosystems, their physical and chemical conditions, and the nature and activity of the organisms that have colonised them. The cryosphere is the domain of extremophiles, organisms able to adapt to the physiological and biochemical challenges of harsh cold conditions where liquid water may only be present for relatively short periods each year. The majority of extremophiles in ice and snow are microorganisms. The Ecology of Snow and Ice Environments is intended for the non-specialist, enabling environmental scientists to understand the biological functioning of extreme cold environments and for biologists to gain knowledge of the nature of the cryosphere.

The ocean helps moderate climate change thanks to its considerable capacity to store CO2, through the combined actions of ocean physics, chemistry, and biology. This storage capacity limits the amount of human-released CO2 remaining in the atmosphere. As CO2 reacts with seawater, it generates dramatic changes in carbonate chemistry, including decreases in pH and carbonate ions and an increase in bicarbonate ions. The consequences of this overall process, known as "ocean acidification," are raising concerns for the biological, ecological, and biogeochemical health of the world's oceans, as well as for the potential societal implications. This research level text is the first to synthesize the very latest understanding of the consequences of ocean acidification, with the intention of informing both future research agendas and marine management policy. A prestigious list of authors has been assembled, among them the coordinators of major national and international projects on ocean acidification.

Global environmental change (including climate change, biodiversity loss, changes in hydrological and biogeochemical cycles, and intensive exploitation of natural resources) is having significant impacts on the world's oceans. This handbook advances knowledge of the structure and functioning of marine ecosystems, and their past, present, and future responses to physical and anthropogenic forcing. It illustrates how climate and humans impact marine ecosystems, providing a comprehensive review of the physical and ecological processes that structure marine ecosystems as well as the observation, experimentation, and modelling approaches required for their study. Recognizing the interactive roles played by humans in using marine resources and in responding to global changes in marine systems, the book includes chapters on the human dimensions of marine ecosystem changes and on effective management approaches in this era of rapid change. A final section reviews the state of the art in predicting the responses of marine ecosystems to future global change scenarios with the intention of informing both future research agendas and marine management policy.
Marine Ecosystems and Global Change provides a detailed synthesis of the work conducted under the auspices of the Global Ocean Ecosystems Dynamics (GLOBEC) program. This research spans two decades, and represents the largest, multi-disciplinary, international effort focused on understanding the impacts of external forcing on the structure and dynamics of global marine ecosystems.

This practical manual of freshwater ecology and conservation provides a state-of-the-art review of the approaches and techniques used to measure, monitor, and conserve freshwater ecosystems. It offers a single, comprehensive, and accessible synthesis of the vast amount of literature for freshwater ecology and conservation that is currently dispersed in manuals, toolkits, journals, handbooks, 'grey' literature, and websites. Successful conservation outcomes are ultimately built on a sound ecological framework in which every species must be assessed and understood at the individual, community, catchment and landscape level of interaction. For example, freshwater ecologists need to understand hydrochemical storages and fluxes, the physical systems influencing freshwaters at the catchment and landscape scale, and the spatial and temporal processes that maintain species assemblages and their dynamics. A thorough understanding of all these varied processes, and the techniques for studying them, is essential for the effective conservation and management of freshwater ecosystems.

This book is the only manual of its kind with exercises that apply to the diverse marine habitats of North America. The manual meets the needs of any introductory marine biology student, from the non-major to the prospective major with a background in the biological sciences. Each unit includes a broad range of exercises, so that instructors using the manual can select the exercises that best match the needs of their introductory course. The manual is also unique in providing extensively illustrated identification keys for three of the major marine lifeforms, allowing students to identify and classify organisms within the invertebrates, plankton, and fishes.

Our oceans are becoming increasingly inhospitable to life--growing toxicity and rising temperatures coupled with overfishing have led many marine species to the brink of collapse. And yet there is one creature that is thriving in this seasick environment: the beautiful, dangerous, and now incredibly numerous jellyfish. As foremost jellyfish expert Lisa-ann Gershwin describes in "Stung , "the jellyfish population bloom is highly indicative of the tragic state of the world's ocean waters, while also revealing the incredible tenacity of these remarkable creatures. Recent documentaries about swarms of giant jellyfish invading Japanese fishing grounds and summertime headlines about armadas of stinging jellyfish in the Mediterranean and Chesapeake are only the beginning--jellyfish are truly taking over the oceans. Despite their often dazzling appearance, jellyfish are simple creatures with simple needs: namely, fewer predators and competitors, warmer waters to encourage rapid growth, and more places for their larvae to settle and grow. In general, oceans that are less favorable to fish are more favorable to jellyfish, and these are the very conditions that we are creating through mechanized trawling, habitat degradation, coastal construction, pollution, and climate change. Despite their role as harbingers of marine destruction, jellyfish are truly enthralling creatures in their own right, and in "Stung ," Gershwin tells stories of jellyfish both attractive and deadly while illuminating many interesting and unusual facts about their behaviors and environmental adaptations. She takes readers back to the Proterozoic era, when jellyfish were the top predator in the marine ecosystem--at a time when there were no fish, no mammals, and no turtles; and she explores the role jellies have as middlemen of destruction, moving swiftly into vulnerable ecosystems. The story of the jellyfish, as Gershwin makes clear, is also the story of the world's oceans, and "Stung "provides a unique and urgent look at their inseparable histories--and future.

This new edition offers a concise but comprehensive introduction to rocky shore ecology and has been completely revised and updated throughout. It describes the diverse biota (invertebrates, vertebrates, seaweeds, seagrasses and microalgae) that inhabit rocky shores, and the factors that determine their distributions, abundances and interactions. The book discusses the latest research on processes that control community structure, utilizing a global range of examples from a wide range of shore types - both temperate and tropical.
The Biology of Rocky Shores begins by describing the shore environment, including the conditions caused by tidal rise and fall as well as an introduction to the effects of waves. It goes on to describe the biodiversity of the rocky shore environment, from seaweeds and cyanobacteria to starfish and oystercatchers, and some of the adaptations these organisms exhibit on the shore. The book discusses in turn the biology of primary producers, grazers, suspension feeders and predators, and the ways in which these trophic groups interact in various communities. The vertical and horizontal distributions of species in relation to the tidal cycle and wave exposure are also considered. The contributions that species make in determining how rocky-shore communities function, and how they interact with off-shore systems, are explored in detail. Human influences, notably pollution, over-fishing and the introduction of alien species, are discussed in the context of rocky shore conservation and future management strategies. A final chapter offers guidance on methods of study, techniques, and experimental approaches.
New to this Edition:
This second edition adds several dimensions to the first, by incorporating the expertise of two new authors, one based in Hong Kong, the other in USA. Since the original edition in 1996, views of how rocky shore communities are regulated have changed, and the book discusses these changes. It is no longer limited to the north-west Atlantic, but covers rocky shores worldwide. It discusses the diversity of shore organisms in terms of functional groups, and it now gives a detailed account of how organisms have adapted to the physical constraints of living on rocky shores. It provides advice on methods and experimental approaches. Black and white photographs and many new line drawings have been added to the original figures.
This new edition also feature 80% new text and 50% new illustrations.
Each of the books in the Oxford Biology of Habitats Series introduces a different habitat, and gives an integrated overview of the design, physiology, ecology, and behaviour of the organisms found there. The practical aspects of working within each habitat, the sorts of studies that are possible, and habitat biodiversity and conservation status are all explored.

Phycology is the study of algae, the primary photosynthetic organisms in freshwater and marine food chains. Since the publication of the first edition in 1981, this textbook has established itself as a classic resource on this subject. Aimed at upper-level undergraduate and graduate students in phycology, limnology and biological oceanography, this revised edition maintains the format of previous editions, whilst incorporating the recent developments in the field such as: the potential and challenges of producing algae biofuel; the proliferation of algal toxins; and the development of new molecular tools and technologies on ancestry, phylogeny, and taxonomy of algae.

This advanced text focuses on the uses of distance sampling to estimate the density and abundance of biological populations. It addresses new methodologies, new technologies and recent developments in statistical theory and is the follow up companion to Introduction to Distance Sampling (OUP, 2001).
In this text, a general theoretical basis is established for methods of estimating animal abundance from sightings surveys, and a wide range of approaches to analysis of sightings data is explored. These approaches include: modelling animal detectability as a function of covariates, where the effects of habitat, observer, weather, etc. on detectability can be assessed; estimating animal density as a function of location, allowing for example animal density to be related to habitat and other locational covariates; estimating change over time in populations, a necessary aspect of any monitoring program; estimation when detection of animals on the line or at the point is uncertain, as often occurs for marine populations, or when the survey region has dense cover; survey design and automated design algorithms, allowing rapid generation of sound survey designs using geographic information systems; adaptive distance sampling methods, which concentrate survey effort in areas of high animal density; passive distance sampling methods, which extend the application of distance sampling to species that cannot be readily detected in sightings surveys, but can be trapped; and testing of methods by simulation, so that performance of the approach in varying circumstances can be assessed.

Providing a comprehensive account of marine conservation, this book examines human use and abuse of the world's seas and oceans and their marine life, and the various approaches to management and conservation. Healthy marine ecosystems - the goods and services that they provide - are of vital importance to human wellbeing. There is a pressing need for a global synthesis of marine conservation issues and approaches. This book covers conservation issues pertinent to major groups of marine organisms, such as sharks, marine turtles, seabirds and marine mammals; key habitats, from estuaries, wetlands and coral reefs to the deep sea; and from local and regional to international initiatives in marine conservation. An ideal resource for students, researchers and conservation professionals, the book pays appropriate attention to the underlying marine biology and oceanography and how human activities impact marine ecosystems, enabling the reader to fully understand the context of conservation action and its rationale.

Temporary waters are found throughout the world, and include intermittent streams and ponds, episodic rain puddles, seasonal limestone lakes, the water-retaining structures of plants, such as bromeliads and pitcher plants, and a variety of man-made container habitats. They are probably populated by various plant, animal, and microscopic communities ranging from the very simple to the highly complex. Temporary waters therefore represent fascinating and significant arenas in which to study the properties of species, as the latter deal with the rigours of living in highly variable environments. Obligate temporary water species display a remarkable array of adaptations to the periodic loss of their primary medium that largely set them apart from the inhabitants of permanent water bodies. Survival of individuals frequently depends upon exceptional physiological tolerance or effective migrational abilities that are timed to appropriate habitat phases. Quite apart from their inherent biological interest, temporary waters are now in the limelight from a conservation perspective as these habitats come more and more into conflict with human activities. Traditionally, many temporary waters (be they ponds, pools, streams, or wetlands) have been considered to be 'wasted' areas of land, potentially convertible to agriculture once drained. In reality, they are natural features of the global landscape that represent distinct and unique habitats for many species, some that are found nowhere else and others that reach their maximum abundance and/or genetic diversity there. Temporary waters are also very important from a human health perspective since they function as breeding places for the vectors of many disease organisms, including those that spread malaria, schistosomiasis, yellow fever, and dengue. Most of these exact a high toll in terms of global human suffering and reduced regional economies. This book collates and synthesises the highly scattered and diverse global literature on pure and applied aspects of these habitats and their biota. It examines the ecology of temporary waters in both natural and human environments, and seeks to identify common evolutionary themes. It will be of particular interest to aquatic ecologists, invertebrate and vertebrate biologists, environmental biologists, wetland managers and conservationists, those charged with controlling water-associated diseases, entomologists, educators, and natural historians.

Fisheries supply a critically important ecosystem service by providing over three billion people with nearly 20% of their daily animal protein intake. Yet one third of the world's fish stocks are currently harvested at unsustainable levels. Calls for the adoption of more holistic approaches to management that incorporate broader ecosystem principles are now being translated into action worldwide to meet this challenge. The transition from concept to implementation is accompanied by the need to further establish and evaluate the analytical framework for Ecosystem-Based Fishery Management (EBFM). The objectives of this novel textbook are to provide an introduction to this topic for the next generation of scientists who will carry on this work, to illuminate the deep and often underappreciated connections between basic ecology and fishery science, and to explore the implications of these linkages in formulating management strategies for the 21st century. Fishery Ecosystem Dynamics will be of great use to graduate level students as well as academic researchers and professionals (both governmental and NGO) in the fields of fisheries ecology and management.

This volume provides a current synthesis of theoretical and empirical food web research. Whether they are binary systems or weighted networks, food webs are of particular interest to ecologists in providing a macroscopic view of ecosystems. They describe interactions between species and their environment, and subsequent advances in the understanding of their structure, function, and dynamics are of vital importance to ecosystem management and conservation. Aquatic Food Webs provides a synthesis of the current issues in food web theory and its applications, covering issues of structure, function, scaling, complexity, and stability in the contexts of conservation, fisheries, and climate. Although the focus of this volume is upon aquatic food webs (where many of the recent advances have been made), any ecologist with an interest in food web theory and its applications will find the issues addressed in this book of value and use. This advanced textbook is suitable for graduate level students as well as professional researchers in community, ecosystem, and theoretical ecology, in aquatic ecology, and in conservation biology.

Authored by a leading team this text is aimed at professionals in government and environment agencies, statisticians, biologists, wildlife managers, conservation biologists and ecologists, as well as graduate students, studying the density and abundance of biological populations.

This lab manual is designed to give students experience with a wide variety of model systems currently in use by developmental biologists. Experiments range from classic slide or whole animal observations to more modern immunohistochemistry and manipulation of gene expression. All of these experiments can be completed on a relatively small budget.

Cephalopods are fast-moving, voracious predators, and can change colour with breath-taking rapidity. They range from the giant squid, the world's largest marine invertebrate, to species of only 2 cm in length. Inhabitants of most seas of the world, they are found from the surface to great depths. Most cephalopods have short lives yet their efficiency in capturing and consuming prey ensures rapid growth. These animals possess highly-developed nervous systems, large brains, elaborate senses, complex behaviour and are capable of learning. Many of these features are described and illustrated with line drawings and photomicrographs.
