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.

Systematists, comparative biologists, taxonomists and evolutionary biologists all concern themselves with the evolutionary relationships between animals and plants. Homology is the principle underlying these disciplines. When looking at groups of organisms, shared positional similarities (homologues) provide the raw data from which hypotheses of common ancestry (homology) may be suggested. In order to explore the relationship between homologues (characters) and particular hypotheses of common ancestry, complex matrices are devised, where homologues are coded, allowing theories of homology to be developed and tested. Practically nothing has been written about this matrix-building process and yet it is of fundamental importance to our understanding of diversity and evolutionary history.
This book fills the gap by discussing the different ways observations are coded and the consequences for the resulting hypotheses. It takes a pragmatic approach and uses real case studies as well as theoretical examples to offer practical solutions and stimulate thinking.

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.

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 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.

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.

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.

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.

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.

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.

This book examines the relationship between classification and evolutionary theory, with reference to the competing schools of taxonomic thinking. Emphasis is placed on one of these schools, the transformed cladists, who have attempted to reject all evolutionary thinking in classification and to cast doubt on evolution in general. The author examines the limits to this line of thought from a philosophical and methodological perspective rather than from a biological viewpoint. He concludes that transformed cladistics does not achieve what it claims and that it either implicity assumes a Platonic World View, or is unintelligible without taking into account evolutionary processes - the very processes it claims to reject. Through this analysis the author attempts to formulate criteria, of an objective and consistent nature, that can be used to judge competing methodologies and theories without resorting to any particular theoretical standpoint for justification. Philosophers of science, zoologists interested in taxonomy and evolutionary biologists will find this a compelling study of an area of biological thought that has been attracting a great deal of attention.

The question of whether biologists should continue to use the Linnaean hierarchy has been a hotly debated issue. Invented before the introduction of evolutionary theory, Linnaeus's system of classifying organisms is based on outdated theoretical assumptions, and is thought to be unable to provide accurate biological classifications. Marc Ereshefsky argues that biologists should abandon the Linnaean system and adopt an alternative that is more in line with evolutionary theory. He traces the evolution of the Linnaean hierarchy from its introduction to the present. 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. Accessible to a wide range of readers by providing introductory chapters to the philosophy of classification and the taxonomy of biology, the book will interest both scholars and students of biology and the philosophy of science.

Until now, individuals wishing to identify British insects have found it difficult to track down the specialist keys published in obscure literature, whereas the popular guides are often misleadingly simplistic, covering only a fraction of the species. This book bridges the gap, providing expert guidance through the taxonomic maze. It contains an introduction to each group of organisms, and over 2000 references selected as being the most useful and up-to-date for accurate identification, together with notes on their relevance and coverage. A further chapter covers the understanding and retrieval of scientific references, with advice on using libraries and other information services. This will be an essential reference book for anyone involved in insect and arachnid identification, from interested amateurs to professionals dealing with unfamiliar groups.

Research conducted over the last fifteen years has placed in question many of the traditional conclusions about the evolution of human female sexuality. Women have not lost estrus, as earlier researchers thought, but it is simply concealed, resulting in two functionally distinct sexualities with markedly different ends in each phase. At the fertile phase of the cycle, women prefer male traits that may mark superior genetic quality, and at infertile phases, they prefer men willing to invest resources in a mate. Thus, women's peri-ovulatory sexuality functions to obtain a sire of superior genetic quality, and is homologous with estrus in other vertebrates. This model sheds light on male human sexuality as well: men perceive and respond to women's estrus, including by increased mate guarding. Men's response is limited, compared to other vertebrate males, implying coevolutionary history of selection on females to conceal estrus from men and selection on men to detect it. Research indicates that women's concealed estrus is an adaptation to copulate conditionally with men other than the pair-bond partner. Women's sexual ornaments-the estrogen-facilitated features of face and body-are honest signals of individual quality pertaining to future reproductive value.

To document the world's diversity of species and reconstruct the tree of life we need to undertake some simple but mountainous tasks. Most importantly, we need to tackle species rich groups. We need to collect, name, and classify them, and then position them on the tree of life. We need to do this systematically across all groups of organisms and because of the biodiversity crisis we need to do it quickly. With contributions from key systematic and taxonomic researchers, Reconstructing the Tree of Life: Taxonomy and Systematics of Species Rich Taxa outlines the core of the problem and explores strategies that bring us closer to its solution. The editors split the book into three parts: introduction and general concepts, reconstructing and using the tree of life, and taxonomy and systematics of species rich groups (case studies). They introduce, with examples, the concept of species rich groups and discuss their importance in reconstructing the tree of life as well as their conservation and sustainable utilization in general. The book highlights how phylogenetic trees are becoming "supersized" to handle species rich groups and the methods that are being developed to deal with the computational complexity of such trees. It discusses factors that have lead some groups to speciate to a staggering degree and also provides case studies that highlight the problems and prospects of dealing with species rich groups in taxonomy. To understand species rich taxa, evolution has set scientists a difficult, but not unattainable, challenge that requires the meshing together of phylogenetics and taxonomy, considerable advances in informatics, improved and increased collecting, training of taxonomists, and significant financial support. This book provides the tools and methods needed to meet that challenge.

The automated identification of biological objects or groups has been a dream among taxonomists and systematists for centuries. However, progress in designing and implementing practical systems for fully automated taxon identification has been frustratingly slow. Regardless, the dream has never died. Recent developments in computer architectures and innovations in software design have placed the tools needed to realize this vision in the hands of the systematics community, not several years hence, but now. And not just for DNA barcodes or other molecular data, but for digital images of organisms, digital sounds, digitized chemical data - essentially any type of digital data. Based on evidence accumulated over the last decade and written by applied researchers, Automated Taxon Identification in Systematics explores contemporary applications of quantitative approaches to the problem of taxon recognition. The book begins by reviewing the current state of systematics and placing automated taxon identification in the context of contemporary trends, needs, and opportunities. The chapters present and evaluate different aspects of current automated system designs. They then provide descriptions of case studies in which different theoretical and practical aspects of the overall group-identification problem are identified, analyzed, and discussed. A recurring theme through the chapters is the relationship between taxonomic identification, automated group identification, and morphometrics. This collection provides a bridge between these communities and between them and the wider world of applied taxonomy. The only book-length treatment that explores automated group identification in systematic context, this text also includes introductions to basic aspects of the fields of contemporary artificial intelligence and mathematical group recognition for the entire biological community.

This volume provides a comprehensive review of the family, Gentianaceae, covering phylogeny, classification, biogeography, palynology, phytochemistry, and morphology, and also presents the first classification of the entire family to be published for over 100 years, generated using modern molecular- and morphology-based phylogenetic data. The volume places the Gentianaceae in context with its relatives in the order Gentianales and subclass Asteridae; presents an updated, phylogenetic classification of tribes, subtribes, and genera; investigates the corroborative value of morphological features in phylogenetic diagnoses; and comprehensively summarizes palynology, seed morphology, and phytochemistry.

Parsimony analysis (cladistics) has long been one of the most widely used methods of phylogenetic inference, in the fields of systematic and evolutionary biology. Moreover it has mathematical attributes that lend itself for use with complex, genomic-scale data sets. This book demonstrates the potential that this powerful hierarchical data summarization method, also has for both structural and functional comparative genomic research.
