This book presents an in-depth discussion of the biological and
ecological geography of the oceans. It synthesizes locally
restricted studies of the ocean to generate a global geography of
the vast marine world.
Fungal pathogens pose an on-going and serious threat for poikilotherms and homeotherms, and can cause a broad spectrum of diseases ranging from innocuous to life-threatening. In addition, long-term exposure to some mycotoxigenic moulds can lead to mycotoxicoses in human and animals. Given the expanding population of immune compromised hosts, the list of fungal opportunists grows longer every year. Moreover, antifungal resistance, drug-related toxicity and our limited arsenal of antifungals have exacerbated the situation. To address these problems, strategies such as the identification of novel targets, use of the structure-activity relationship in rational drug design, development of new formulations, modification of existing antifungals to combat resistance, and bioavailability enhancement are called for. For the reader's convenience, this book has been divided into three sections. The first six chapters of Section I provide a timely review of mycoses, from endemic to cosmopolitan and from generalized to specific, while both chapters of Section II focus on risks associated with mycotoxins. In closing, the two chapters of Section III describe potential antifungal leads and drug candidates based on phytochemicals and coumarin scaffold.
This book covers pot-pollen-the other product, besides honey, stored in cerumen pots by Meliponini. Critical assessment is given of stingless bee and pot-pollen biodiversity in the Americas, Africa, Asia and Oceania. Topics addressed include historical biogeography, cultural knowledge, bee foraging behavior, pollination, ecological interactions, health applications, microbiology, the natural history of bee nests, and chemical, bioactive and individual plant components in stored pollen. Pot-pollen maintains the livelihoods of stingless bees and provides many interesting biological products that are just now beginning to be understood. The Meliponini have developed particular nesting biologies, uses of building materials, and an architecture for pollen storage. Environmental windows provide optimal temperature and availability of pollen sources for success in plant pollination and pollen storage. Palynological composition and pollen taxonomy are used to assess stingless honey bee pollination services. Pollen processing with microorganisms in the nest modifies chemical composition and bioactivity, and confers nutraceutical benefits to the honey and pollen widely relished by native people. Humans have always used stingless bees. Yet, sustainable meliponiculture (stingless bee-keeping) projects have so far lacked a treatise on pot-pollen, which experts provide in this transdisciplinary, groundbreaking volume.
Thorp and Covich's Freshwater Invertebrates: Keys to Nearctic Fauna, Fourth Edition presents a comprehensive revision and expansion of this trusted professional reference manual and educational textbook-from a single North American tome into a developing multivolume series covering inland water invertebrates of the world. Readers familiar with the first three editions will welcome this new volume. The series, now entitled Thorp and Covich's Freshwater Invertebrates, (edited by J.H. Thorp), began with Volume I: Ecology and General Biology, (edited by J.H. Thorp and D.C. Rogers). It now continues in Volume II with taxonomic coverage of inland water invertebrates of the Nearctic zoogeographic region. As in previous editions, all volumes of the fourth edition are designed for multiple uses and levels of expertise by professionals in universities, government agencies, and private companies, as well as by undergraduate and graduate students.
In Loe Bar and the Sandhill Rustic Moth, Adrian Spalding examines the survival of plants and animals on Loe Bar, a shingle beach on the coast of Cornwall, in the context of its history, geomorphology and exposure to the Atlantic environment. He develops these themes within a detailed study of the Sandhill Rustic moth that endures this harsh environment where storm surges, high salinity, high temperatures, strong winds and burial by sand affect the wildlife that occurs there.
The book will cover the entire range of the Painted Stork--beyond its stronghold in India and Sri Lanka to other countries--E Asia as well. For the sake of comparison, relevant information will be included about the other species of storks--both solitary as well as colonial, of Asia, as well as those in other parts of the world. Certainly plenty of references will be made about the work done on the American Wood Stork. Studies are underway in order to better understand the role of the monsoon rains on the nesting pattern of Painted Stork, besides attempting a review of the global status of the species. The former is likely to be of interest in augmenting our understanding about how global climate change is going to affect birds across India and the second is likely to raise interesting points about the distribution of species and their ranges. Both these studies will be carried through 2009 and should hopefully be included in the proposed book. Naturally, the focused interest in field research on the Painted Stork has resulted in accumulation of considerable information on this particular species, which is beyond the information contained on some standard Indian and international works and ornithological texts. The author hopes to include the entire spread of information of this species--from its systematics, evolution, distribution, ecology to its role in human culture as well as its association with mythologies. In other words, topics have not been restricted to the areas of the author s research but have spilled over into areas of anthropology, ecology, conservation, etc. "
Things have changed. In 1969 when the Convention for the Conservation of the Vicuna was drafted, in an attempt to save the vicuna from its tumbling decline towards extinction, both the science and the philosophy of wildlife conservation were radically different. It is thus a tribute to the prescience of those involved at the time that the rescue plan had, even through the harsh lens of hindsight, a d- tinctly Twenty First Century flavour. After all, it was predicated on the expectation that if vicuna could be saved, they would one day become a valued asset, generating revenue for the human communities that fostered their survival. Embodied in this aspiration are the main structures of modern biodiversity conservation - not only is it to be underpinned by science, but that science should be of both the natural and the social genres, woven into inter-disciplinarity, and thereby taking heed of e- nomics, governance, ownership and the like, alongside biology. In addition, it should include, as a major strut, the human dimension, taking account of the affected constituencies with their varied stakes in alternative outcomes. This c- temporary framework for thinking about biodiversity conservation is inseparable from such wider, and inherently political, notions as community-based conser- tion and ultimately sustainable use.
Coral Reef Fishes is the successor of "The Ecology of Fishes on
Coral Reefs." This new edition includes provocative reviews
covering the major areas of reef fish ecology. Concerns about the
future health of coral reefs, and recognition that reefs and their
fishes are economically important components of the coastal oceans
of many tropical nations, have led to enormous growth in research
directed at reef fishes. Coral Reef Fishes is much more than a
simple revision of the earlier volume; it is a companion that
supports and extends the earlier work. The included syntheses
provide readers with the current highlights in this exciting
science.
A summary of much of the experimental work on the spatial ecology of small mammals. This field has entered an exciting stage with such new techniques as GIS and systems modeling becoming available. Leading contributors describe and analyze the most well-known case studies and provide new insights into how landscape patterns and processes have had an impact on small mammals and how small mammals have, in turn, affected landscape structure and composition.
The mighty and majestic European bison is the relictual embodiment of the wildness of prehistoric Europe. Tragically, the millennia since that time have seen so many species driven to extinction by human impacts, and the European bison has only narrowly avoided the same fate. Today, the species represents the symbolic sentinel of successful conservation actions in a world in which such achievements remain few and far between. From an early stage in the restitution of the European bison, husband-and-wife team Ma gorzata Krasi ska and Zbigniew A. Krasi ski have been participating in relevant management initiatives and researching all facets of the bison, from its morphology and diet, to its movements, social life and reproduction, and the conservation management actions that have been taken to save it. Now they have summarised this wealth of knowledge on the species, giving rise to a publication ideal for students, professional biologists and conservationists, but also for all nature enthusiasts. This new edition of the monograph offers extensively updated content taking into account research carried out on the European bison in the last few years. Also featured, a new chapter devoted to knowledge of the genetics of the species drawn up by Ma gorzata Tokarska of the Bia owie a-based Mammal Research Institute PAS.
With its focus on the practical application of the techniques of multivariate statistics, this book shapes the powerful tools of statistics for the specific needs of ecologists and makes statistics more applicable to their course of study. It gives readers a solid conceptual understanding of the role of multivariate statistics in ecological applications and the relationships among various techniques, while avoiding detailed mathematics and the underlying theory. More importantly, the reader will gain insight into the type of research questions best handled by each technique and the important considerations in applying them. Whether used as a textbook for specialised courses or as a supplement to general statistics texts, the book emphasises those techniques that students of ecology and natural resources most need to understand and employ in their research. While targeted for upper-division and graduate students in wildlife biology, forestry, and ecology, and for professional wildlife scientists and natural resource managers, this book will also be valuable to researchers in any of the biological sciences.
This Naturalists' Handbook aims to attract more people to the study of solitary wasps by describing the ecology, distribution and natural history of these insects, including all relevant research in one convenient volume. Contents include an overview of the natural history of the solitary wasp, guidelines on identification, and advice on techniques and approaches to study. Further reading, a systematic checklist of genera and an alphabetical checklist of species and their distributions are included. Detailed keys to the identification of the species form the centre of the book and the text is accompanied by clear illustrations throughout, making this an invaluable practical guide for anyone seeking to broaden their knowledge of these fascinating, diverse creatures. Smaller, gentler and less intimidating than the black and yellow social wasps, the solitary wasps are attractive because of their bright colours and their fascinating behaviour. A female wasp will construct a nest, excavating it from wood or sand or building it from mud. She provisions the nest with prey, hunting down a suitable creature, perhaps a caterpillar or a fly, which she will paralyse before dragging it home to the nest. She lays her egg on the paralysed prey, and the larva when it hatches feeds on the prey. On a sunny day it is easy to observe the apparently purposeful behaviour of female wasps as they prepare their nests and stock them with food for the next generation. This book is a digital reprint of ISBN 0-85546-295-7 (1995). Naturalists' Handbooks encourage and enable those interested in natural history to undertake field study, make accurate identifications and to make original contributions to research.
Most organisms and populations have to cope with hostile environments, threatening their existence. Their ability to respond phenotypically and genetically to these challenges and to evolve adaptive mechanisms is, therefore, crucial. The contributions to this book aim at understanding, from a evolutionary perspective, the impact of stress on biological systems. Scientists, applying different approaches spanning from the molecular and the protein level to individuals, populations and ecosystems, explore how organisms adapt to extreme environments, how stress changes genetic structure and affects life histories, how organisms cope with thermal stress through acclimation, and how environmental and genetic stress induce fluctuating asymmetry, shape selection pressure and cause extinction of populations. Finally, it discusses the role of stress in evolutionary change, from stress induced mutations and selection to speciation and evolution at the geological time scale. The book contains reviews and novel scientific results on the subject. It will be of interest to both researchers and graduate students and may serve as a text for graduate courses.
The assemblage of animals living in sandy shores is richer than it might first appear, and it offers wonderful opportunities for ecological explanation without the need for expensive equipment. This book introduces the natural history of the community and provides keys that will enable readers to name the animals they find. It provides practical approaches for behavioural and ecological studies, including the survey and monitoring of populations. Local investigations of this kind form an essential basis for planning the conservation of sandy shore habitats, which are important both in their own right and as feeding grounds for birds. This is a digital reprint edition of the book originally published in 1994 with ISBNs 0855462949 (hbk) & 0855462930 (pbk).
This book attempts to advance Donald Griffin's vision of the "final, crowning chapter of the Darwinian revolution" by developing a philosophy for the science of animal consciousness. It advocates a Darwinian bottom-up approach that treats consciousness as a complex, evolved, and multi-dimensional phenomenon in nature, rather than a mysterious all-or-nothing property immune to the tools of science and restricted to a single species. The so-called emergence of a science of consciousness in the 1990s has at best been a science of human consciousness. This book aims to advance a true Darwinian science of consciousness in which its evolutionary origin, function, and phylogenetic diversity are moved from the field's periphery to its very centre; thus enabling us to integrate consciousness into an evolutionary view of life. Accordingly, this book has two objectives: (i) to argue for the need and possibility of an evolutionary bottom-up approach that addresses the problem of consciousness in terms of the evolutionary origins of a new ecological lifestyle that made consciousness worth having, and (ii) to articulate a thesis and beginnings of a theory of the place of consciousness as a complex evolved phenomenon in nature that can help us to answer the question of what it is like to be a bat, an octopus, or a crow. A Philosophy for the Science of Animal Consciousness will appeal to researchers and advanced students interested in advancing our understanding of animal minds, as well as anyone with a keen interest in how we can develop a science of animal consciousness.
The present monograph is the fourth of six volumes which review the Hypotricha, a major group of the spirotrichs. The book is about the Gonostomatidae, the Kahliellidae, and some taxa of unknown position in the hypotrichs. Gonostomum was previously misclassified in the Oxytrichidae because its type species Gonostomum affine has basically an 18-cirri pattern, which is dominant in the oxytrichids. A new hypothesis, considering also molecular data, postulates that this 18-cirri pattern evolved in the last common ancestor of the hypotrichs and therefore it appears throughout the Hypotricha tree. The simple dorsal kinety pattern, composed of only three bipolar dorsal kineties, and gene sequence analyses strongly suggest that Gonostomum branches off rather early in the phylogenetic tree. Thus, the Gonostomatidae, previously synonymised with the oxytrichids, are reactivated to include the name-bearing type genus and other genera (e.g., Paragonostomum, Wallackia, Cladotricha) which have the characteristic gonostomatid oral apparatus. The Kahliellidae are a rather vague group mainly defined via the preservation of parts of the parental infraciliature. The kahliellids preliminary comprise, besides the name-bearing type genus Kahliella, genera such as Parakahliella and its African pendant Afrokahliella or the monotypic Engelmanniella. In total 68 species distributed in 21 genera and subgenera are revised. As in the previous volumes almost all morphological, morphogenetic, molecular, faunistic, and ecological data, scattered in almost 700 papers, are compiled so that the four volumes (Oxytrichidae, Urostyloidea, Amphisiellidae and Trachelostylidae, Gonostomatidae and Kahliellida) provide a detailed insight into the biology of almost 500 species of hypotrichs. The series is an up-to-date overview about this highly interesting taxon of spirotrichous ciliates mainly addressed to taxonomists, cell biologists, ecologists, molecular biologists, and practitioners.
In the past two decades, an increasing number of ecologists have started to investigate the importance of biodiversity for ecological processes such as energy flow and nutrient cycling, often referred to as 'ecosystem functioning'. Insects are a dominant component of biodiversity in terrestrial ecosystems and play a key role in mediating the relationship between plants and ecosystem processes. This volume is the first to summarize their effects on ecosystem functioning, focusing mainly, but not exclusively, on herbivorous insects. Renowned authors with extensive experience in the field of plant-insect interactions, contribute to the volume using examples from their own work. In addition to providing concise reviews of the field, this volume discusses in detail the advantages and disadvantages of various techniques of manipulating insect herbivory. Thus, the text provides both a theoretical basis as well as practical advice for future manipulative studies of biodiversity-ecosystem functioning.
Mites are very small animals, characterized by wingless and eyeless bodies, in which sociality has been discovered. This book offers detailed descriptions of the diverse social systems and the social evolution of mites, ranging from genetic to ecological aspects. Through a broad spectrum of studies including traditional natural history, taxonomy, modern evolutionary and behavioral ecology, and theoretical models as well, the book addresses a number of important findings on plant mite evolution and species radiation, with the author succeeding in combining theoretical and practical approaches in behavioral ecology by proposing a new game theory. These findings reflect the complex evolutionary history of these taxa and also help to point out clearly what is known and what is not yet known to date. Mites have been considered a minor animal group, but the author shows that mites actually possess great diversity and therefore make unique materials for evolutionary and behavioral studies.
Many endangered species of wild animals are managed in captivity through studbooks. In this book these data-rich resources are mined in innovative, integrated and statistically tested ways to maximise information gain for conservation practice - whether for captive or released/reintroduced or managed wild populations. This book is thus an important tool for all species managers, and for students and researchers in small population biology and wildlife conservation. The book's studbook analyses are grouped in three interrelated sections: natural history, demography and genetics. Statistical tests to determine the significance of results or to compare results between subgroups are undertaken throughout. Real studbooks of a variety of species, e.g. cranes, wolverines, blesbok, illustrate the practical applications and interpretations of the analyses and statistics. The "natural history" section presents analyses to determine baseline species information such as litter size, inter-birth interval, longevity and seasonality. "Demography" covers census(-style) analyses, age-class based life tables, comparative survival analyses and population projections. Solutions for dealing with small sample sizes are included.Inbreeding depression and unconscious selection form the main focus of the "genetics" section. Survival and life table analyses are used to assess inbreeding effects. Quantitative genetics methods are applied to natural history traits as a tool to monitor genetic variation. A fourth section on "conservation" shows how data from captive populations can be used where natural history data from wild populations are missing. A real example uses studbook data to inform Population Viability Analysis. The final section deals with issues related to incomplete and missing data and statistical topics. The purpose-written open-source software programs "Population Management Library (PML)" and "studbookR" used for analyses in the book, are available at www.princee.com.
Regional intercomparisons between ecosystems on different continents can be a powerful tool to better understand the ways in which ecosystems respond to global change. Large areas are often needed to characterize the causal mechanisms governing interactions between ecozones and their environments. Factors such as weather and climate patterns, land-ocean and land-atmosphere interactions all play important roles. As a result of the strong physical north-south symmetry between the western coasts of North and South America, the similarities in climate, coastal oceanography and physiography between these two regions have been extensively documented. High Latitude Rain Forests and Associated Ecosystems of the West Coast of the Americas presents current research on West Coast forest and river ecology, and compares ecosystems of the Pacific Northwest with those of South America.
The international advanced research workshop funded by NATO and entitled "impact of pollutions on animal and animal products" was organized at Almaty (Kazakhstan) on 27-30 September 2007. Thirty-one scientists from 12 countries (Kazakhstan, Kirgizstan, Azerbaijan, Ukraine, Russia, France, Great Britain, Italy, Belgium, Romania and Morocco) presented conferences at this meeting to share their experience and results. The programme included three main aspects: (i) generality on the pollution situation in Central Asia and former Soviet Union republics, (ii) the pollution area and pollution origin in Central Asia and Western countries in relation with animal health, and (iii) the relationships between soil contamination, plant contamination and animal products status. The present workshop contributed highly to the exchange between scientists giving the opportunity for researchers from Central Asia to access to new scientific approaches and methodologies, and for European scientists to assess the extent of the environmental problems in this part of the world. No doubt that these exchanges were the main success of the workshop marked by very stimulating discussions. Such meeting was also the opportunity to put on the first stone of a scientific network focused on the subject of the workshop. The importance of pollution in Central Asia in general and in Kazakhstan in p- ticular is a well-known feature and several references are available on the source and localization of pollution problems in those countries. The references are also abundant on the impact of the environmental failures on human health.
Homing phenomena must be considered an important aspect of animal behaviour on account of their frequent occurrence, their survival value, and the variety of the mechanisms involved. Many species regularly rely on their ability to home or reach other familiar sites, but how they manage to do this is often uncertain. In many cases the goal is attained in the absence of any sensory contact, by mechanisms of indirect orientation whose complexity and sophistication have for a long time challenged the skill and patience of many researchers. A series of problems of increasing difficulty have to be overcome; researchers have to discover the nature of orienting cues, the sensory windows involved, the role of inherited and acquired information, and, eventually, how the central mechanisms process information and control motory responses. Naturally, this book emphasizes targets achieved rather than areas unexplored and mysteries unsolved. Even so, the reader will quickly realize that our knowledge of phenomena and mechanisms has progressed to different degrees in different animal groups, ranging from the mere description of homing behaviour to a satisfactory insight into some underlying mechanisms. In the last few dacades there have been promising developments in the study of animal homing, since new approaches have been tried out, and new species and groups have been investigated. Despite this, homing phenomena have not recently been the object of exhaustive reviews and there is a tendency for them to be neglected in general treatises on animal behaviour.
This book should be of interest to students of animal ecology; ecology.
This book is an attempt to compile and integrate the information documented by many botanists, both Egyptians and others, about the vegetation of Egypt. The ? rst treatise on the ? ora of Egypt, by Petrus Forsskal, was published in 1775. Records of the Egyptian ? ora made during the Napoleonic expedition to Egypt (1778-1801) were provided by A. R. Delile from 1809 to 1812 (Kassas, 1981). The early beginning of ecological studies of the vegetation of Egypt extended to the mid-nineteenth century. Two traditions may be recognized. The ? rst was general exploration and survey, for which one name is symbolic: Georges-Auguste Schweinfurth (1836-1925), a German scientist and explorer who lived in Egypt from 1863 to 1914. The second tradition was ecophysiological to explain the plant life in the dry desert. The work of G. Volkens (1887) remains a classic on xeroph- ism. These two traditions were maintained and expanded in further phases of e- logical development associated with the establishment of the Egyptian University in 1925 (now the University of Cairo). The ? rst professor of botany was the Swedish Gunnar Tackholm (1925-1929). He died young, and his wife Vivi Tackholm devoted her life to studying the ? ora of Egypt and gave leadership and inspiration to plant taxonomists and plant ecologists in Egypt for some 50 years. She died in 1978. The second professor of botany in Egypt was F. W. |
