The diversity of social behavior among birds and primates is surpassed only by members of the Hymenopteran insects, including bees, ants, and the genus Polistes, or paper-wasps. This volume combines incisive reviews and new, unpublished data in studies of paper-wasps, a large and varied group whose life patterns are often studied by biologists interested in social evolution. While this research is significant to the natural history of paper-wasps, it also applies to topics of general interest such as the evolution of cooperation, social parasitism, kin recognition, and the division of labor.

The deep sea covers more than half the surface of the Earth, but until the circumnavigation made by the HMS Challenger almost nothing was known about the animals that live there. Full Fathom 5000 gives an account of the remarkable discoveries that were made during the voyage and describes the strange and bizarre creatures that live in perpetual darkness a kilometer or more below the surface of the sea. Until the early 1870s, very little was known about the creatures lurking in the depths of our oceans. People had found a few things trapped in fishing gear or caught on the anchors of ships, but those who tried to venture to the bottom of the seafloor often died before they made it there. The first systematic investigation into life in our oceans was made during the circumnavigation of the HMS Challenger. Scientists credit this voyage as the beginning of modern oceanography, and the story of it is full of twists and turns. It led to the discovery of a whole new fauna previously unknown, which Full Fathom 5000 describes for the first time in one place for readers. In this book, Graham Bell takes readers through the voyage station by station, following the progress of the expedition and introducing some of the new and strange animals that were hauled up from the depths of the ocean and seen by human eyes for the first time. You will meet, among others, the ugliest fish in the world, flesh-eating clams, dwarf males, sea devils, and an octopus that wears lipstick. The book begins with a description of the first attempts scientists made to explore the deep sea, leading up to the plan for a voyage around the world on the HMS Challenger. The chapters take readers from station to station, though all of the world's oceans, visiting every continent and crossing the Equator five times. Bell details what was discovered during hundreds of stops to take samples, and he describes around a hundred stations where remarkable animals were hauled from the sea. The book ends with a description of what came after the end of this journey, explaining what they did with the animals that were collected and what became of the scientists and sailors who planned the voyage and traveled together around the world.

Leaf beetles are one of the largest groups of beetles, with tens of thousands of species worldwide and around 280 in Britain. They belong mainly to the family Chrysomelidae, but also to two small closely related families, the Megalopodidae and Orsodacnidae. This book provides a comprehensive overview with detailed and accessible coverage of the natural history, ecology and biology of leaf beetles. Topics cover the life history of leaf beetles, biology, their environment, natural enemies and interactions with humans. There is a thorough discussion about identification of British species, including detail on the juvenile stages (eggs, larvae, pupae) and a concise key to adults. A chapter is dedicated to study techniques and materials. The book is illustrated throughout with colour photographs and line drawings. Leaf beetles is a vital resource for entomology students and educators, naturalists, nature conservationists, those involved in agriculture, horticulture and the management of stored produce.

Biologists and laypeople alike have repeatedly claimed victory over life. A thousand years ago we thought we knew almost everything, a hundred years ago, too. But even today, Rob Dunn argues, discoveries we can't yet imagine still await us. More is unknown than known, whether about our bodies or the bottom of the sea.

In a series of vivid portraits of scientists as interesting as the mysteries they chase, Dunn introduces the reader to breakthroughs that have changed the world and others that might still. With poetry and humor, Dunn reminds readers how tough and exhilarating it is to study the natural world, and why it matters.

Written in an accessible style by internationally renowned authors in the field, readers are straightforwardly guided through fundamental principles and terminology. Simple worked examples and easy-to-understand diagrams also help readers navigate complex problems that have perplexed scientists for centuries. This practical guide is an essential addition for advanced undergraduates, postgraduates and researchers in taxonomy, systematics, comparative biology, evolutionary biology and molecular biology.

This Tiny Folio presents, in modern taxonomic order, all 277 of the hand-coloured plates from François-André Michaux’s classic North American Sylva, as well as the supplemental volumes by Thomas Nuttall. These masterworks of 19th-century botanical illustration - by such artists as Pierre-Joseph Redouté and Pancrace Bessa - represent the leaves, fruit, and flowers of American trees with wonderful grace and clarity. Published in cooperation with the New York Botanical Garden, The Trees of North America includes a preface and introduction describing how Michaux and Nuttall’s pioneering work came to be.

Cryptic species are organisms which look identical, but which represent distinct evolutionary lineages. They are an emerging trend in organismal biology across all groups, from flatworms, insects, amphibians, primates, to vascular plants. This book critically evaluates the phenomenon of cryptic species and demonstrates how they can play a valuable role in improving our understanding of evolution, in particular of morphological stasis. It also explores how the recognition of cryptic species is intrinsically linked to the so-called 'species problem', the lack of a unifying species concept in biology, and suggests alternative approaches. Bringing together a range of perspectives from practicing taxonomists, the book presents case studies of cryptic species across a range of animal and plant groups. It will be an invaluable text for all biologists interested in species and their delimitation, definition, and purpose, including undergraduate and graduate students and researchers.

The advent of relational databasing and data storage capacity, coupled with revolutionary advances in molecular sequencing technology and specimen imaging, have led to a taxonomic renaissance. Systema Naturae 250 - The Linnaean Ark maps the origins of this renaissance, beginning with Linnaeus, through his "apostles," via the great unsung hero Charles Davies Sherbon arguably the father of biodiversity informatics up to the present day with the Planetary Biodiversity Inventories and into the future with the Encyclopedia of Life and web-based taxonomy.

The book provides scientific, historical, and cultural documentation of the evolution of taxonomy and the successful adaptation of the Linnaean nomenclature system to that evolution. It underscores the importance of taxonomic accuracy, not only for the classification of living organisms, but for a more complete understanding of the living world and its biodiversity. The book also examines the role of technologies such as DNA sequencing, specimen imaging, and electronic data storage.

A celebration of 250 years of the scientific naming of animals, Systema Naturae 250 - The Linnaean Ark records and explores the history of zoological nomenclature and taxonomy, detailing current and future activity in these fields. Descriptive taxonomy has been in decline, despite the fact that the classification of organisms through taxonomic studies provides the foundation of our understanding of life forms. Packed with illustrations and tables, this book establishes a vision for the future of descriptive taxonomy and marks the beginning of a period of rapid growth of taxonomic knowledge.

The focus of the present edition has been to further consolidate the information on the principles of plant systematic, include detailed discussion on all major systems of classification, and significantly, also include discussion on the selected families of vascular plants, without sacrificing the discussion on basic principles. The families included for discussion are largely those which have wide representation, as also those that are less known but significant in evaluating the phylogeny of angiosperms. The discussion of the families also has a considerable focus on their phylogenetic relationships, as evidenced by recent cladistic studies, with liberal citation of molecular data. Several additional families have been included for detailed discussion in the present volume.

This book provides a conceptually organized framework to understand the phenomenon of biological invasions at the Anthropocene global scale. Most advances toward that aim have been provided from North American and European researchers, with fewer contributions from Australia and South Africa. Here we fill the void from the Neotropics, focusing on the research experience in South American countries, with a strong emphasis on Argentina and Chile. The text is divided into two parts: The first half comprises self-contained chapters, providing a conceptual, bibliographic and empirical foundation in the field of invasion biology, from an Anthropocene perspective. The second half reviews the ecology, biogeography, and local impacts in South America of exotic species groups (European rabbit, Eurasian wild boar, Canadian beaver, North American mink, and Holarctic freshwater fishes), which are shown to be useful models for case studies of global relevance.

Natural resources and associated biological diversity provide the basis of livelihood for human population, particularly in the rural areas and mountain regions across the globe. Asia is home to the world's highest mountain regions including the Himalayas, Karakorum and Hindukush. These regions are renowned around the globe because of their unique beauty, climate, and biocultural diversity. Because of geoclimatic conditions, the mountains of Asia are medicinal and food plant diversity hot spots. The indigenous communities residing in the valleys of these mountains have their own culture and traditions, and have a long history of interaction with the surrounding plant diversity. Local inhabitants of these mountains areas possess significant traditional knowledge of plant species used as food, medicine, and for cultural purposes. So far, many workers have reported traditional uses of plant species from different regions of Asia including some mountain areas; however, there is not one inclusive document on the ethnobotany of mountains in Asia. This book provides a comprehensive overview on ethno-ecological knowledge and cross cultural variation in the application of plant species among various communities residing in the mountains of Asia; cross cultural variation in traditional uses of plant species by the mountain communities; high value medicinal and food plant species; and threats and conservation status of plant species and traditional knowledge. This book should be useful to researchers of biodiversity and conservation, ethnobiologists, ethnoecologists, naturalists, phytochemists, pharmacists, policy makers, and all who have a devotion to nature.

A unique collection of concise but detailed information on 10,000 animals, plants, fungi and algae of the British Isles. Every species with an English common name is included. The compendium is in two parts. The first, smaller part, looks at various terms that people interested in natural history may come across. The second provides information on individual species or species groups, with entries on those with English (common) names, as well as selected families, orders, classes, etc. In the case of marine organisms, entries are given for intertidal and subtidal invertebrate species, and generally speaking for fish species that might be observed inshore. Indication is often given on distribution as well as whether a species is common, scarce or something in between. For some species a note is made of population size and trends. Comments are made where appropriate on etymology, both of the English name and the binomial. No other natural history dictionary or cognate publication relating to the British Isles is as comprehensive in taxonomic cover.

Microbes are ubiquitous in nature. Among microbes, fungal communities play an important role in agriculture, the environment, and medicine. Vast fungal diversity has been associated with plant systems, namely epiphytic fungi, endophytic fungi, and rhizospheric fungi. These fungi associated with plant systems play an important role in plant growth, crop yield, and soil health. Rhizospheric fungi, present in rhizospheric zones, get their nutrients from root exudates released by plant root systems, which help with their growth, development, and microbe activity. Endophytic fungi typically enter plant hosts through naturally occurring wounds that are the result of plant growth, through root hairs, or at epidermal conjunctions. Phyllospheric fungi may survive or proliferate on leaves depending on material influences in leaf diffuseness or exudates. The diverse nature of these fungal communities is a key component of soil-plant systems, where they are engaged in a network of interactions endophytically, phyllospherically, as well as in the rhizosphere, and thus have emerged as a promising tool for sustainable agriculture. These fungal communities promote plant growth directly and indirectly by using plant growth promoting (PGP) attributes. These PGP fungi can be used as biofertilizers and biocontrol agents in place of chemical fertilizers and pesticides for a more eco-friendly method of promoting sustainable agriculture and environments. This first volume of a two-volume set covers the biodiversity of plant-associated fungal communities and their role in plant growth promotion, the mitigation of abiotic stress, and soil fertility for sustainable agriculture. This book should be useful to those working in the biological sciences, especially for microbiologists, microbial biotechnologists, biochemists, and researchers and scientists of fungal biotechnology.

Chaetomium genus was established by Gustav Kunze in 1817. According to Index Fungorum Partnership, there are 273 Chaetomium species accepted till now. Members of the genus Chaetomium are capable of colonizing various substrates and are well-known for their ability to degrade cellulose and to produce a variety of bioactive metabolites. More than 200 compounds have been reported from this genus. A huge number of new and bioactive secondary metabolites associated with unique and diverse structural types, such as chaetoglobosins, epipolythiodioxopiperazines, azaphilones, depsidones, xanthones, anthraquinones, chromones, and steroids, have been isolated and identified. Many of the compounds have been reported to possess significant biological activities, such as antitumor, antimalarial, cytotoxic, enzyme inhibitory, antimicrobial, phytotoxic, antirheumatoid and other activities. Chaetomium taxa are frequently reported to be cellulase and ligninase producers with the ability to degrade cellulosic and woody materials. This is the first, comprehensive volume covering Chaetomium genus in detail. It includes the latest research, methods, and applications, and was written by scholars working directly in the field. The book also contains informative illustrations and is fully referenced for further reading.

This book provides a knowledge-based view to the dynamic capabilities in an organization. The author integrates two existing views on gaining competitive advantage: the Knowledge View which suggests that the capability of organizations to learn faster than competitors is the only source of competitiveness; and the Dynamic Capability View which speculates that a fi rm's competitive advantage rests on it's ability to adapt to changes in the business environment. Using the IT sector in India as a case study, this book provides and tests a new framework-Knowledge-Based Dynamic Capabilities-in the prediction of competitive advantage in organizations.

This is the second of three volumes of "Keys to the Trematoda," a series on the systematics and identification of the Class Trematoda. The book presents the taxa in the Order "Echinostomida" and some of those in the Order "Plagiorchiida," with keys for their identification at the superfamily, family, subfamily and generic levels. The keys are based on critical examination of specimens by subject experts, and generic diagnoses are accompanied by illustrations of important morphological characters. This volume includes seven echinostomidan superfamilies (the echinostomatoids, haploporoids, haplosplanchnoids, heronimoids, microscaphidioids, paramphistomatoids and pronocephaloids) and two plagiorchiidan superfamilies (the allocreadioids and lepocreadioids). The first volume covered the Subclass "Aspidogastrea" and Order "Strigeida," while the third volume, due to be published in early 2006, will cover the remaining members of the Plagiorchiida.

Nematodes that are parasites of insects are no longer a laboratory curiosity. They have begun to be accepted as environmentally benign alternatives to the use of chemical insecticides, for the control of insect pests. Nematode worms are now applied as biological control agents against insect pests of numerous horticultural and agricultural crops.This book provides a comprehensive review of entomopathogenic nematology. It begins by reviewing fundamental biology and setting a taxonomic foundation for nematodes and their bacterial symbionts. Several chapters are devoted to functional processes involved in parasitism and to nematode ecology. Later chapters describe technological advances and control methodologies.

For centuries, botanists have been drawn to the rarest species, sometimes with dire consequences for the species' survival. In this book, Great Britain's rarest flowering plants are discussed in turn, including the stories behind their discovery, the reasons for their rarity, and the work being done to save them from dying out. It is hoped that it will help to throw light on some of the species that normally gain little attention, and foster an appreciation of our most threatened plants. This guide describes 66 native species of plants that have the most narrowly restricted ranges in Great Britain. These range from continental, warmth-loving species in the south of England to those found only on the highest Scottish mountains. Each species is shown together with its habitat to allow the reader to better understand the ecological context. Other scarce plants in the same area are indicated.

Modern biological classification is based on the system developed by Linnaeus, and interpreted by Darwin as representing the tree of life. But despite its widespread acceptance, the evolutionary interpretation has some problems and limitations. This comprehensive book provides a single resource for understanding all the main philosophical issues and controversies about biological classification. It surveys the history of biological classification from Aristotle to contemporary phylogenetics and shows how modern biological classification has developed and changed over time. Readers will also be able to see how biological classification is in part a consequence of human psychology, language development and culture. The book will be valuable for student readers and others interested in a range of topics in philosophy and biology.

There is long-standing disagreement among systematists about how to divide biodiversity into species. Over twenty different species concepts are used to group organisms, according to criteria as diverse as morphological or molecular similarity, interbreeding and genealogical relationships. This, combined with the implications of evolutionary biology, raises the worry that either there is no single kind of species, or that species are not real. This book surveys the history of thinking about species from Aristotle to modern systematics in order to understand the origin of the problem, and advocates a solution based on the idea of the division of conceptual labor, whereby species concepts function in different ways - theoretically and operationally. It also considers related topics such as individuality and the metaphysics of evolution, and how scientific terms get their meaning. This important addition to the current debate will be essential for philosophers and historians of science, and for biologists.

In an age when biodiversity is being lost at an unprecedented rate, it is vital that floristic and faunistic information is up to date, reliable and easily accessible for the formulation of effective conservation strategies. Electronic data management and communication are transforming descriptive taxonomy radically, enhancing both the collection and dissemination of crucial data on biodiversity. This volume is written by scientists at the forefront of current developments of floras and faunas, along with specialists from applied user groups. The chapters review novel methods of research, development and dissemination, which aim to maximise the relevance and impact of data. Regional case studies are used to illustrate the outputs and impacts of taxonomic research. Integrated approaches are presented which have the capacity to accelerate the production of floras and faunas and to better serve the needs of a widening audience.

Frederick Orpen Bower (1855-1948) was a renowned botanist best known for his research on the origins and evolution of ferns. Appointed Regius Professor of Botany at the University of Glasgow in 1885, he became a leading figure in the development of modern botany and the emerging field of paleobotany, devising the interpolation theory of the life cycle in land plants. First published between 1923 and 1928 as part of the Cambridge Botanical Handbook series, The Ferns was the first systematic classification of ferns according to anatomical, morphological and developmental features. In this three-volume work Bower analyses the major areas of comparison between different species, describes primitive and fossil ferns and compares these species to present-day fern species, providing a comprehensive description of the order. Volume 1 describes and analyses the features of ferns which Bower uses in his system of classification.
