Classification of plants and animals is of basic interest to biologists in all fields because correct formulation and generalization are based on sound taxonomy. This book by a world authority relates traditional taxonomic studies to recent developments in biochemical and other fields. It provides guidelines for the integration of modern and traditional methods and explains the underlying principles and philosophy of systematics. The problems of zoological, botanical, and paleontological classification are dealt with in great detail and microbial systematics briefly. Science may be defined as the rational and objective study of the external universe by human beings. Whether the study of man himself is included, as part of science will depend on how we interpret 'human beings' in this definition. If we regard humanity as in essence an assemblage of isolated individuals, then anyone of them may regard the rest as part of the external universe and thus as 'material' for scientific study; on the other hand, if, humanity is regarded as essentially one body and science as a collective rather than an individual function, we can hardly avoid maintaining in some form or other the traditional distinction between the sciences and the humanities. The problems of classifying human beings will not be considered in detail in this book, though it will appear that if the criteria developed for other animals were applied to our own case, the chimpanzee, the gorilla and perhaps the orangutan would join us in the genus Homo. This book deals with questions that are of direct relevance to the work of all biologists as well as of all specialists in taxonomy. In addition, the clarity of the author's exposition and his felicitous style make it challenging reading for all undergraduate and graduate students in the biological sciences. R.A. Crowson (1914-1999) was lecturer in Zoological Taxonomy at the University of Glasgow. His Antipodean expedition to Australia and New Zealand was made possible by the Leverhume research fellowship, and he was able to explore America when the Museum of Comparative Zoology at Harvard University appointed him to the Alexander Agassiz visiting lectureship in 1969. The 1968 Congress of Entomology in Moscow enabled him to meet many Russian scientists with whom he had corresponded for several years. His wide-ranging interests and travels allowed Dr. Crowson to bring a truly international outlook to bear upon his subject.

The border between the United States of America and Mexico is the busiest in the world. This area is also the meeting place of the two great cultures of the Western Hemisphere, Spanish-speaking Latin America and English-speaking North America. Recent demographic migrations coupled with increasing globalization have necessitated closer cooperation and communication between these groups.

The area of communication of this dictionary centers around the vernacular or common names of plants. Many recent immigrants from Mexico and further south have gained employment in areas of agriculture, landscaping, and commercial plant nurseries. The new residents also bring with them a rich history of herbal medicines that are becoming increasingly popular in the United States. Both groups share interests in each other's cuisines with respect to food plants and spices.

This dictionary contains the Latin, English, and Spanish names for over 7,000 species of the most important plants found mainly in the southwestern United States and northern Mexico. Included are native and naturalized plants as well as plants of economic value. The main section of the book is organized alphabetically by the scientific Latin genus and species of each plant. The book is also fully indexed by common names primarily in American-English and Mexican-Spanish.

Confusion about the genera Geranium and Pelargonium existed even before Linnaeus' binomial system of classification bundled both into the former category in 1753. Despite later evaluations that separated the two, many practitioners of alternative medicine and aromatherapists, among others, remain unaware of the distinction. Laymen and plant sales personnel are often equally in the dark - the majority of garden centre 'geraniums' are Pelargonium species and cultivars. This work aims to dispel myths and peel away layers of incorrect and muddled information which contribute to the unclear image of the genera.
Geranium and Pelargonium: History of Nomenclature, Usage and Cultivation features discussion and new information on some of the following areas:
* taxonomy and history of usage and nomenclature
* cultivation for essential oil production and retail purposes in different countries
* phytochemistry of the genera
* chemistry of Geranium and Pelargonium oils
* theory and practice of distillation of Geranium and Pelargonium oils
* pharmacology an therapeutic properties of Geranium and Pelargonium oils and extracts
* use of Geranium and Pelargonium products in aromatherapy, perfumery, cosmetics, food processing and medicine
* new research into Geranium and Pelargonium
This book will be of interest to graduate students, scientists and professionals in the Geranium and Pelargonium growing and retail industry, the perfumery, food and cosmetics industries, and to those interested in Geranium and Pelargonium for alternative and conventional medical use.
* Theory and practice of distillation

This series of books is a translation of Flora Evropeiskoi Chasti SSR, which provides information on the wild and most important cultivated plants growing in the European portion of Russia and its bordering regions. The text describes plant systematics, habitat conditions, range, and chromosome numbers. The series serves as a manual for botanists, agronomists, teachers, students and naturalists. Volume 5 includes descriptions of 608 species from 133 genera and 23 families belonging to the orders Salicales, Erocales, Diapensiales, Ebenales, Primulares (, Polemoniales, and Scrophulariales.

Many species of penicillium and aspergillus are important in biotechnology, food, medicine, biodeterioration and other applied fields, so a practical and stable taxonomy is of vital importance. Recent developments in science and technology mean that taxonomic classification is no longer confined to classical morphological concepts, and the integration of molecular, physiological and biochemical methods now plays an important role in understanding the classification of these fungi. Integration of Modern Taxonomic Methods for Penicillium and Aspergillus Classification brings together a collection of chapters from international experts in this field. It will be of value to researchers and professionals in mycology, biotechnology, medicine and regulatory agencies interested in the identification of these fungi.

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.

The relationship between systematics and ecology has recently been invigorated, and developed a long way from the "old" field of comparative biology. This change has been two-fold. Advances in phylogenetic research have allowed explicit phylogenetic hypotheses to be constructed for a range of different groups of organisms, and ecologists are now more aware that organism traits are influenced by the interaction of past and present. This volume discusses the impact of these modern phylogenetic methods on ecology, especially those using comparative methods.
Although unification of these areas has proved difficult, a number of conclusions can be drawn from the text. These include the need for a "working" bridge between evolutionary biologists using logic-based cladistic methods and those using probability-based statistical methods, for care in the selection of tree types for comparative studies and for systematists to attempt to analyse ecologically important groups.
Comparative ecologists and systematists need to come together to develop these ideas further, but this volume presents a very useful starting point for all those interested in systematics and ecology.

An engaging history of the surprising, poignant, and occasionally scandalous stories behind scientific names and their cultural significance, "More fun than you've ever had with taxonomy in your whole entire life!" (Diana Gabaldon, author of the Outlander series and PhD in Quantitative Behavioral Ecology) Ever since Carl Linnaeus's binomial system of scientific names was adopted in the eighteenth century, scientists have been eponymously naming organisms in ways that both honor and vilify their namesakes. This charming, informative, and accessible history examines the fascinating stories behind taxonomic nomenclature, from Linnaeus himself naming a small and unpleasant weed after a rival botanist to the recent influx of scientific names based on pop-culture icons-including David Bowie's spider, Frank Zappa's jellyfish, and Beyonce's fly. Exploring the naming process as an opportunity for scientists to express themselves in creative ways, Stephen B. Heard's fresh approach shows how scientific names function as a window into both the passions and foibles of the scientific community and as a more general indicator of the ways in which humans relate to, and impose order on, the natural world.

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.

'Species' are central to understanding the origin and dynamics of biological diversity; explaining why lineages split into multiple distinct species is one of the main goals of evolutionary biology. However the existence of species is often taken for granted, and precisely what is meant by species and whether they really exist as a pattern of nature has rarely been modelled or critically tested. This novel book presents a synthetic overview of the evolutionary biology of species, describing what species are, how they form, the consequences of species boundaries and diversity for evolution, and patterns of species accumulation over time. The central thesis is that species represent more than just a unit of taxonomy; they are a model of how diversity is structured as well as how groups of related organisms evolve. The author adopts an intentionally broad approach, stepping back from the details to consider what species constitute, both theoretically and empirically, and how we detect them, drawing on a wealth of examples from microbes to multicellular organisms.

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.

Designed as an introduction to the intriguing world of insect biology, this book examines familiar entomological topics in nontraditional ways. Author David B. Rivers gives important concepts relatable context through a pop culture lens, and he covers subjects that are not typical for entomology textbooks, including the impact of insects on the human condition, the sex lives of insects, why insects are phat but not fat, forensic entomology, and the threats that some insects pose to humanity. Each chapter presents clear and concise key concepts, chapter reviews, review questions following Bloom's taxonomy of learning, web links to videos and other resources, and breakout boxes (called Fly Spots) that capture student interest with unique and entertaining facts related to entomology. Focusing on both traditional and cutting-edge aspects of insect biology and packed with extensive learning resources, Insects covers a wide range of topics suitable for life science majors, as well as non-science students, including: * the positive and negative influences of insects on everyday human life* insect abundance* insect classification (here presented in the context of social media)* insect feeding, communication, defense, and sex* how insects are responding to climate change* forensic entomology* how insects can be used as weapons of war* how insects relate to national security* why insects have wings* how to read pesticide labels

This book is the third volume in the Handbook of Zoology series which treats the systematics and biology of Coleoptera. With approximately 350,000 described species, Coleoptera are by far the most species-rich order of insects and the largest group of animals of comparable geological age. This third Coleoptera volume completes the Morphology and Systematics volumes with 43 chapters and covers one of the largest radiations of beetles, the mainly plant-feeding Phytophaga, with information on world distribution, biology, morphology of all life stages (including anatomy), phylogeny and comments on taxonomy.

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.

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.

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.

This volume of the series Handbook of Zoology deals with the anatomy of the gastrointestinal digestive tract - stomach, small intestine, caecum and colon - in all eutherian orders and suborders. It presents compilations of anatomical studies, as well as an extensive list of references, which makes widely dispersed literature accessible. Introductory sections to orders and suborders give notice to biology, taxonomy, biogeography and food of the respective taxon. It is a characteristic of this book that different sections of the post-oesophageal tract are discussed separately from each other. Informations on form and function of organs of digestion in eutherians are discussed under comparative-anatomical aspects. The variability and diversity of anatomical structures represents the basis of functional differentiations.

This is an essential reference for describing, measuring and classifying the foliage of flowering plants. The presented system provides long-needed guidelines for characterizing the organization, shape, venation, and surface features of angiosperm leaves. In contrast to systems focusing on reproductive characters for identification, the emphasis is on macroscopic features of the leaf blade including leaf characters, venation, and tooth characters. The advantage of this system is that it allows for the classification of plants independently of their flowers, which is especially useful for fossil leaves (usually found in isolation) and tropical plants (whose flowering cycles are brief and irregular, and whose fruits and flowers may be difficult to access). An illustrated terminology including detailed definitions and annotated illustrations is the focus of the classification system, the aim of which is to provide a framework with comparative examples to allow both modern and fossil leaves to be described and classified consistently.

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.

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.

This revised edition of Bats of Southern and Central Africa builds on the solid foundation of the first edition and supplements the original account of bat species then known to be found in Southern and Central Africa with an additional eight newly described species, bringing the total to 124. The chapters on evolution, biogeography, ecology and echolocation have been updated, citing dozens of recently published papers. The book covers the latest systematic and taxonomic studies, ensuring that the names and relationships of bats in this new edition reflect current scientific knowledge. The species accounts provide descriptions, measurements and diagnostic characters as well as detailed information about the distribution, habitat, roosting habits, foraging ecology and reproduction of each species. The updated species distribution maps are based on 6 100 recorded localities. A special feature of the 2010 publication was the mode of identification of families, genera and species by way of character matrices rather than the more generally used dichotomous keys. Since then these matrices have been tested in the field and, where necessary, slightly altered for this edition. New photographs fill in gaps and updated sonograms aid with bat identification in acoustic surveys. The bibliography, which now contains more than 700 entries, will be an invaluable aid to students and scientists wishing to consult original research.

The Insects has been the standard textbook in the field since the first edition published over forty years ago. Building on the strengths of Chapman's original text, this long-awaited 5th edition has been revised and expanded by a team of eminent insect physiologists, bringing it fully up-to-date for the molecular era. The chapters retain the successful structure of the earlier editions, focusing on particular functional systems rather than taxonomic groups and making it easy for students to delve into topics without extensive knowledge of taxonomy. The focus is on form and function, bringing together basic anatomy and physiology and examining how these relate to behaviour. This, combined with nearly 600 clear illustrations, provides a comprehensive understanding of how insects work. Now also featuring a richly illustrated prologue by George McGavin, this is an essential text for students, researchers and applied entomologists alike.

Historical biogeography-the study of the history of species through both time and place-first convinced Charles Darwin of evolution. This field was so important to Darwin's initial theories and line of thinking that he said as much in the very first paragraph of On the Origin of Species (1859) and later in his autobiography. His methods included collecting mammalian fossils in South America clearly related to living forms, tracing the geographical distributions of living species across South America, and sampling peculiar fauna of the geologically young Galapagos Archipelago that showed evident affinities to South American forms. Over the years, Darwin collected other evidence in support of evolution, but his historical biogeographical arguments remained paramount, so much so that he devotes three full chapters to this topic in On the Origin of Species. Discussions of Darwin's landmark book too often give scant attention to this wealth of evidence, and we still do not fully appreciate its significance in Darwin's thinking. In Origins of Darwin's Evolution, J. David Archibald explores this lapse, showing how Darwin first came to the conclusion that, instead of various centers of creation, species had evolved in different regions throughout the world. He also shows that Darwin's other early passion-geology-proved a more elusive corroboration of evolution. On the Origin of Species has only one chapter dedicated to the rock and fossil record, as it then appeared too incomplete for Darwin's evidentiary standards. Carefully retracing Darwin's gathering of evidence and the evolution of his thinking, Origins of Darwin's Evolution achieves a new understanding of how Darwin crafted his transformative theory.
