This volume provides a comprehensive account of the systematic vegatative anatomy of the plant family Iridaceae. The iris family includes several horticulturally important genera, such as Iris Crocus, Gladiolus and Freesia, and many others of potential horticultural value. The book contains much original information, and places it in the context of the taxonomy and relationships of the plants concerned. It also summarizes the relevant literature. Like its predecessors in the Anatomy of the Monocotyledons series, Volume VIII: Iridaceae will be an essential reference work for students and professionals in botany and horticulture.

Latin is one of two acceptable languages for describing new plants, and taxonomists must be able to translate earlier texts in Latin. Providing a simple explanation of Latin grammar along with an in-depth vocabulary, this is an indispensable guide for systematic botanists worldwide. All relevant parts of speech are discussed, with accompanying examples as well as worked exercises for translating diagnoses and descriptions to and from Latin. Guidelines for forming specific epithets are also included. The authors cross-reference their grammar to Stearn's Botanical Latin and to articles in the International Code of Nomenclature for Algae, Fungi and Plants. The comprehensive vocabulary is enhanced with terms from recent glossaries for non-flowering plants - lichens, mosses, algae, fungi and ferns - making this an ideal resource for anyone looking to hone their understanding of Latin grammar and to translate botanical texts from the past 300 years.

Systematics has developed rapidly during the past two decades. A multitude of new methods and contributions from a diversity of biological fields including molecular genetics and developmental biology have provided a wealth of phylogenetic hypotheses, some confirming traditional views others contradicting them. Despite such inconsistencies, it is now possible to recognize robust regions of a 'tree of life' and also to identify problematic areas which have yet to be resolved. This is the first book to apply the current state of phylogeny to an evolutionary interpretation of animal organ systems and body architecture, providing alternative theories in those cases of continuing controversy.
Organs do not appear suddenly during evolution; instead they are composed of far simpler structures. In some cases it is even possible to trace particular molecules or physiological pathways as far back as pre-animal history. What emerges is a fascinating picture, showing how animals have combined ancestral and new elements in novel ways to form constantly changing responses to environmental requirements.
The Evolution of Organ Systems starts with a general overview of current animal phylogeny, followed by review of general body organization including symmetry, anteroposterior axis, dorsoventral axis, germ layers, segmentation, and skeletons. Subsequent chapters then provide a detailed description of the individual organ systems themselves - integument, musculature, nervous system, sensory organs, body cavities, excretory system, circulatory system, respiratory system, intestinal system, gonads and gametes. Generously illustrated throughout, this accessible text is suitable for both upper levelundergraduate and graduate students taking courses in animal evolution, organogenesis, animal anatomy, zoology and systematics. It will also be a valuable reference tool for those professional researchers in these fields requiring an authoritative, balanced and up-to-date overview of the topic.

This book illustrates the key role played by taxonomy in the conservation and sustainable utilisation of plant biodiversity. It is a tribute to the work of Professor Vernon Heywood who has done so much to highlight the importance of sound scholarship, training and collaboration for plant conservation. Divided into four parts, the book opens with an overview of the place of taxonomy in science and in implementing the Convention on Biological Diversity. Part 2 outlines the theoretical basis of taxonomy, how it is done and how it contributes to measuring diversity. The third part explains how taxonomy is used to establish conservation priorities and actions and the concluding part illustrates taxonomy in the practice and measurement of effective conservation action. With contributions from taxonomists and also the users of taxonomy, the volume will provide a balanced treatment, suitable for advanced students, researchers and conservation professionals.

This text can be read at many levels. Not least it is an extraordinary inventory - an illustrated summary of all the Earthly creatures that have ever lived. Whatever living thing you come across, from E-coli to an oak tree or an elephant, this book will show you what kind of creature it is, and how it relates to all others. Yet there are far too many creatures to present merely as a catalogue. The list of species already described is vast enough - nearly two million - but there could in reality be as many as 30 million different animals, plants, fungi and protists - and perhaps another 400 million different bacteria and archaea. In the 4000 million years or so since life first began on Earth, there could have been several thousand billion different species. The only way to keep track of so many is to classify - placing similar creatures into categories, which nest within larger categories, and so on. As the centuries have passed, so it has become clear that the different groups are far more diverse than had ever been appreciated. Thus Linneus in the 18th century placed all living things in just two kingdoms, Animals and Plants.

The question of whether biologists should continue to use the Linnaean hierarchy is a hotly debated issue. Invented before the introduction of evolutionary theory, Linnaeus' system of classifying organisms is based on outdated theoretical assumptions, and is thought to be unable to provide accurate biological classifications. Ereshefsky argues that biologists should abandon the Linnaean system and adopt an alternative that is more in line with evolutionary theory. He illustrates how the continued use of this system hampers our ability to classify the organic world, and then goes on to make specific recommendations for a post-Linnaean method of classification.

Scaling relationships are a persistent theme in biology. Examples include branching patterns of blood vessels, structural and functional correlates of body size, distribution of body size and abundance among species, and variations in populations within an area or over time. This book, based on a conference at the Santa Fe Institute, brings together many of the most prominent workers in the area to assess our current understanding of scaling relationships at the physiological, biomechanical, and ecological levels.

HONG De-Yuan's three-volume monograph of the popular genus Paeonia is a comprehensive taxonomic revision, based on extensive field observations, population sampling, examination of more than 5,000 specimens, and multidisciplinary study. This final volume in the series focusses on the biology, phylogeny and evolution of Paeonia, illustrated with over 200 photographs, line drawings and maps. This is an essential reference for taxonomists, growers, breeders, horticulturalists and general biologists.

A revised and fully updated edition encourages the reader to view existing classification systems objectively as it reflects upon the rapid advances that have occurred since the first edition's publication.

Human Population Biology is a careful integration of the social and biological sciences, drawing on anthropology, biology, human ecology and medicine to provide a comprehensive understanding of how our species adapts to natural and man-made environments. The book's chapters fall into five parts. In Part I, techniques to adapt and apply large-scale demographic methods to smaller populations, particularly important for studying non-Western populations, are presented. In Part II, the relationship of medical genetics to human adaptability and patterns of disease epidemiology in small, non-Western populations are discussed. In Part III work capacity, climatic stress and nutrition are covered. In Part IV methods for growth assessment and prediction are presented and ageing is addressed. The final section, Part V, presents integrated case studies of human adaptation to high altitude, and patterns of modernization and stress resulting from cultural change.

While there have been controversial attempts to link conclusions from sociobiological studies of animal populations to humans, few behavioral scientists or anthropologists have made serious progress. In this work, Austin Hughes presents a unique and well-defined theoretical approach to human social behavior that is rooted in evolutionary biology and sociobiology, and which is additionally viewed as a direct continuation of the structural-functional tradition in anthropological research. Using mathematical and statistical techniques, Hughes applies the principles of kin selection theory--which states that natural selection can favor social acts that increase the fitness of both individuals and their relatives--to anthropological data. Among the topics covered are the subdivision of kin groups, selection of leaders in traditional societies, patronage systems, and the correspondence between social and biological kinship. The author concludes that patterns of concentration of relatedness are more important than average relatedness for predicting social behavior. He also shows that social interactions can often be predicted on the basis of common genetic interest in dependent offspring. The result is a major contribution to the field of behavioral biology.

Although the species is one of the fundamental units of biological classification, there is remarkably little consensus among biologists about what defines a species, even within distinct sub-disciplines. The literature of paleobiology, in particular, is littered with qualifiers and cautions about applying the term to the fossil record or equating such species with those recognized among living organisms. In Species and Speciation in the Fossil Record, experts in the field examine how they conceive of species of fossil animals and consider the implications these different approaches have for thinking about species in the context of macroevolution. After outlining views of the Modern Synthesis of evolutionary disciplines and detailing the development within paleobiology of quantitative methods for documenting and analyzing variation within fossil assemblages, contributors explore the challenges of recognizing and defining species from fossil specimens and offer potential solutions. Addressing both the tempo and mode of speciation over time, they show how with careful interpretation and a clear species concept, fossil species may be sufficiently robust for meaningful paleobiological analyses. Indeed, they demonstrate that the species concept, if more refined, could unearth a wealth of information about the interplay between species origins and extinctions, between local and global climate change, and greatly deepen our understanding of the evolution of life.

Over the past hundred years, gulls have been brought ashore by modernity. They now live not only on the coasts but in our slipstream following trawlers, barges, and garbage trucks. They are more our contemporaries than most birds, living their wild lives among us in towns and cities. In many ways they live as we do, walking the built-up world and grabbing a bite where they can. Yet this disturbs us. We've started fearing gulls for getting good at being among us. We see them as scavengers, not entrepreneurs; ocean-going aliens, not refugees. They are too big for the world they have entered. Their story is our story too. Landfill is the original and compelling story of how in the Anthropocene we have learned about the natural world, named and catalogued it, and then colonized it, planted it, or filled it with our junk. While most other birds have gone in the opposite direction, hiding away from us, some vanishing forever, gulls continue to tell us how the wild can share our world. For these reasons Landfill is the nature book for our times, groundbreaking and genre-bending. Without nostalgia or eulogy, it kicks beneath the littered surface of the things to discover stranger truths.

Understanding the history and philosophy of biological systematics (phylogenetics, taxonomy and classification of living things) is key to successful practice of the discipline. In this thoroughly revised Third Edition of the classic Biological Systematics, Andrew V. Z. Brower and Randall T. Schuh provide an updated account of cladistic principles and techniques, emphasizing their empirical and epistemological clarity. Brower and Schuh cover: -the history and philosophy of systematics -the mechanics and methods of character analysis, phylogenetic inference, and evaluation of results -the practical application of systematic results to: -biological classification -adaptation and coevolution -biodiversity,and conservation -new chapters on species and molecular clocks Biological Systematics is both a textbook for students studying systematic biology and a desk reference for practicing systematists. Part explication of concepts and methods, part exploration of the underlying epistemology of systematics, This third edition addresses why some methods are more empirically sound than others.

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.

This 2-volume set is written by the grandfather of Charles Darwin. The purpose of the books is to reduce the facts belonging to animal life into classes, orders, genera, and species; and, by comparing them with each other, to unravel the theory of diseases.

An authoritative guide to the identification, systematics, distribution, and biology of the thirty-eight species of the Order Beloniformes in the western North Atlantic Ocean The final volume in the Fishes of the Western North Atlantic series covers the Beloniformes, a diverse order of fishes containing six families and at least two hundred and thirty extant species found worldwide in marine and freshwater environments. This excellently illustrated, authoritative book describes the thirty-eight species of beloniform fishes-needlefishes, sauries, halfbeaks, and flyingfishes-that live in the western Atlantic Ocean. Compiled from new revisions, original research, and critical reviews of existing information, this tenth book in the series completes a major reference work in taxonomy and ichthyology for both amateurs and professionals, and all students of the sea.

The Fishes of the Western North Atlantic series, which began publication in the 1940s by Yale University's Sears Foundation for Marine Research, was from its beginnings conceived to synthesize and make accessible the wealth of information in widely scattered published accounts of the fish fauna of the region for both the layman and the specialist, presenting critical reviews rather than compilations. These reference works are still considered valuable and of interest today to both general audiences and the academic community. As described in the Preface to the first volume, the series was "written on the premise that it should be useful to those in many walks of life-to those casually ... interested ..., to the sportsman ..., to the fisherman ..., as well as to the amateur ichthyologist and the professional scientist." These books remain authoritative studies of the anadromous, estuarine, and marine fishes of the waters of the western North Atlantic from Hudson Bay southward to the Amazon, ranking as primary references for both amateurs and professionals interested in fishes, and as significant working tools for students of the sea.
