Most projects in Landscape Ecology, at some point, define a species-habitat association. These models are inherently spatial, dealing with landscapes and their configurations. Whether coding behavioral rules for dispersal of simulated organisms through simulated landscapes, or designing the sampling extent of field surveys and experiments in real landscapes, landscape ecologists must make assumptions about how organisms experience and utilize the landscape. These convenient working postulates allow modelers to project the model in time and space, yet rarely are they explicitly considered. The early years of landscape ecology necessarily focused on the evolution of effective data sources, metrics, and statistical approaches that could truly capture the spatial and temporal patterns and processes of interest. Now that these tools are well established, we reflect on the ecological theories that underpin the assumptions commonly made during species distribution modeling and mapping. This is crucial for applying models to questions of global sustainability. Due to the inherent use of GIS for much of this kind of research, and as several authors’ research involves the production of multicolored map figures, there would be an 8-page color insert. Additional color figures could be made available through a digital archive, or by cost contributions of the chapter authors. Where applicable, would be relevant chapters’ GIS data and model code available through a digital archive. The practice of data and code sharing is becoming standard in GIS studies, is an inherent method of this book, and will serve to add additional research value to the book for both academic and practitioner audiences.

Describing Species

Practical Taxonomic Procedure for Biologists

New species are discovered every day—and cataloguing all of them has grown into a nearly insurmountable task worldwide. Now, this definitive reference manual acts as a style guide for writing and filing species descriptions. New collecting techniques and new technology have led to a dramatic increase in the number of species that are discovered. Explorations of unstudied regions and new habitats for almost any group of organisms can result in a large number of new species discoveries—and hence the need to be described. Yet there is no one source a student or researcher can readily consult to learn the basic practical aspects of taxonomic procedures. Species description can present a variety of difficulties: Problems arise when new species are not given names because their discoverers do not know how to write a formal species description or when these species are poorly described. Biologists may also have to deal with nomenclatural problems created by previous workers or resulting from new information generated by their own research. This practical resource for scientists and students contains instructions and examples showing how to describe newly discovered species in both the animal and plant kingdoms. With special chapters on publishing taxonomic papers and on ecology in species description, as well as sections covering subspecies, genus-level, and higher taxa descriptions, Describing Species enhances any writer's taxonomic projects, reports, checklists, floras, faunal surveys, revisions, monographs, or guides. The volume is based on current versions of the International Codes of Zoological and Botanical Nomenclature and recognizes that systematics is a global and multicultural exercise. Though Describing Species has been written for an English-speaking audience, it is useful anywhere Taxonomy is spoken and will be a valuable tool for professionals and students in zoology, botany, ecology, paleontology, and other fields of biology.

Species Concepts and Phylogenetic Theory

A Debate

No question in theoretical biology has been more perennially controversial or perplexing than "What is a species?" Recent advances in phylogenetic theory have called into question traditional views of species and spawned many concepts that are currently competing for general acceptance. Once the subject of esoteric intellectual exercises, the "species problem" has emerged as a critically important aspect of global environmental concerns. Completion of an inventory of biodiversity, success in conservation, predictive knowledge about life on earth, management of material resources, formulation of scientifically credible public policy and law, and more depend upon our adoption of the "right" species concept. Quentin D. Wheeler and Rudolf Meier present a debate among top systematic biology theorists to consider the strengths and weaknesses of five competing concepts. Debaters include (1) Ernst Mayr (Biological Species Concept), (2) Rudolf Meier and Rainer Willmann (Hennigian species concept), (3) Brent Mishler and Edward Theriot (one version of the Phylogenetic Species Concept), (4) Quentin Wheeler and Norman Platnick (a competing version of the Phylogenetic Species Concept), and (5) E. O. Wiley and Richard Mayden (the Evolutionary Species Concept). Each author or pair of authors contributes three essays to the debate: first, a position paper with an opening argument for their respective concept of species; second, a counterpoint view of the weakness of competing concepts; and, finally, a rebuttal of the attacks made by other authors. This unique and lively debate format makes the comparative advantages and disadvantages of competing species concepts clear and accessible in a single book for the first time, bringing to light numerous controversies in phylogenetic theory, taxonomy, and philosophy of science that are important to a wide audience. Species Concepts and Phylogenetic Theory will meet a need among scientists, conservationists, policy-makers, and students of biology for an explicit, critical evaluation of a large and complex literature on species. An important reference for professionals, the book will prove especially useful in classrooms and discussion groups where students may find a concise, lucid entrée to one of the most complex questions facing science and society.

Molecular approaches have opened new windows on a host of ecological and evolutionary disciplines, ranging from population genetics and behavioral ecology to conservation biology and systematics. Molecular Markers, Natural History and Evolution summarizes the multi-faceted discoveries about organisms in nature that have stemmed from analyses of genetic markers provided by polymorphic proteins and DNAs. The first part of the book introduces rationales for the use of molecular markers, provides a history of molecular phylogenetics, and describes a wide variety of laboratory methods and interpretative tools in the field. The second and major portion of the book provides a cornucopia of biological applications for molecular markers, organized along a scale from micro-evolutionary topics (such as forensics, parentage, kinship, population structure, and intra-specific phylogeny) to macro-evolutionary themes (including species relationships and the deeper phylogenetic structure in the tree of life). Unlike most prior books in molecular evolution, the focus is on organismal natural history and evolution, with the macromolecules being the means rather than the ends of scientific inquiry. Written as an intellectual stimulus for the advanced undergraduate, graduate student, or the practicing biologist desiring a wellspring of research ideas at the interface of molecular and organismal biology, this book presents material in a manner that is both technically straightforward, yet rich with concepts and with empirical examples from the world of nature.

This important collection focuses on the nature and importance of biodiversity. The concept is clarified and its intrinsic and instrumental value are discussed. Even though the term biodiversity was invented in the 1980s to promote the cause of species conservation, discussions on biological diversity go back to Plato. There are many controversies surrounding biodiversity and a few of them are examined here: What is worthy of protection or restoration and what is the acceptable level of costs? Is it permissible to kill sentient animals to promote native populations? Can species be reintroduced if they have disappeared a long time ago? How should the responsibilities for biodiversity be shared? This book will be of interest to philosophers of science and biologists, but also to anyone interested in conservation and the environment.

This book began life as a series of lectures given to second andthird year undergraduates at Oxford University. Theselectures were designed to give students insights as to how marineecosystems functioned, how they were being affected by natural andhuman interventions, and how we might be able to conserve them andmanage them sustainably for the good of people, both recreationallyand economically. This book presents 10 chapters, beginningwith principles of oceanography important to ecology, throughdiscussions of the magnitude of marine biodiversity and the factorsinfluencing it, the functioning of marine ecosystems at withintrophic levels such as primary production, competition anddispersal, to different trophic level interactions such asherbivory, predation and parasitism. The final three chapterslook at the more applied aspects of marine ecology, discussionfisheries, human impacts, and management and conservation. Other textbooks covering similar topics tend to treat the topicsfrom the point of view of separate ecosystems, with chapters onreefs, rocks and deep sea. This book however is topic drivenas described above, and each chapter makes full use of examplesfrom all appropriate marine ecosystems. The book is illustratedthroughout with many full colour diagrams and high qualityphotographs. The book is aimed at undergraduate and graduate students atcolleges and universities, and it is hoped that the many examplesfrom all over the world will provide global relevance andinterest. Both authors have long experience of research and teaching inmarine ecology. Martin Speight’s first degree was inmarine zoology at UCNW Bangor, and he has taught marine ecology andconservation at Oxford for 25 years. His research studentsstudy tropical marine ecology from the Caribbean through EastAfrica to the Far East. Peter Henderson is a Senior ResearchAssociate at the University of Oxford, and is Director of PiscesConservation in the UK. He has worked on marine andfreshwater fisheries, as well as ecological and economic impactsand exploitation of the sea in North and South America as well asEurope.

We live in a well-engineered universe. This engineering is present in every system and organism in existence, including in the actions and interactions of plants and animals. In fact, one could say that the function and movement of plants and animals is just as much a part of their makeup as chlorophyll and fiber or bone and blood. Consequently, if we want to understand the ecology of animals and plants especially in an integrated ecosystem, it follows that great insight can be gained by taking an approach that studies function and integration of parts rather than the individual parts themselves. Ecology and Biomechanics: A Mechanical Approach to the Ecology of Animals and Plants offers a collection of state-of-the-art papers that ingeniously demonstrates how biomechanics can provide novel insights into long standing ecological and evolutionary questions. The majority of the book's chapters were originally presented at a symposium held at the annual meeting of the Society for Experimental Biology in Edinburgh, U.K., in 2004. Combining approaches from various disciplines, this volume covers subjects that encompass theoretical concepts and practical approaches involving research on both plants and animals, as well as interactions between the two. Although most of the examples emphasize distinct organism-environment relationships such as the grazing of ruminants, the book also includes a few examples that span larger temporal and spatial scales, achieving wider application across ecosystems. This can be seen in the chapter Implications of Microbial Motility on the Water Column Ecosystems, which highlights how microbial ecosystems can be understood from the mechanics, morphology, and motile responses of the individual organisms. Designed to serve as a reference for students and researchers, Ecology and Biomechanics: A Mechanical Approach to the Ecology of Animals and Plants paves the way for further research by demonstrating what can happen when the approaches from two seemingly disparate subdisciplines within the field of biology are creatively combined.

Floral Mimicry

Mimicry is a classic example of adaptation through natural selection. The traditional focus of mimicry research has been on defence in animals, but there is now also a highly-developed and rapidly-growing body of research on floral mimicry in plants. This has coincided with a revolution in genomic tools, making it possible to explore which genetic and developmental processes underlie the sometimes astonishing changes that give rise to floral mimicry. Being literally rooted to one spot, plants have to cajole animals into acting as couriers for their pollen. Floral mimicry encompasses a set of evolutionary strategies whereby plants imitate the food sources, oviposition sites, or mating partners of animals in order to exploit them as pollinators. This first definitive book on floral mimicry discusses the functions of visual, olfactory, and tactile signals, integrating them into a broader theory of organismal mimicry that will help guide future research in the field. It addresses the fundamental question of whether the evolutionary and ecological principles that were developed for protective mimicry in animals can also be applied to floral mimicry in plants. The book also deals with the functions of floral rewardlessness, a condition which often serves as a precursor to the evolution of mimicry in plant lineages. The authors pay particular attention to the increasing body of research on chemical cues: their molecular basis, their role in cognitive misclassification of flowers by pollinators, and their implications for plant speciation. Comprehensive in scope and conceptual in focus, Floral Mimicry is primarily aimed at senior undergraduates, graduate students, and researchers in plant science and evolutionary biology.

Consciously or not, wildlife managers generally act from a theoretical basis, although they may not be fully versed in the details or ramifications of that theory. In practice, the predictions of the practitioners sometimes prove more accurate than those of the theoreticians. Practitioners and theoreticians need to work together, but this proves difficult when new management ideas and cutting-edge ecological theory are often published in separate scientific outlets with distinctly different readerships. A compilation of the scientific papers presented at the Caesar Kleberg Wildlife Research Institute's 25th Anniversary Conference of April 2006, Wildlife Science: Linking Ecological Theory and Management Applications brings together these two often separate approaches to elucidate the theoretical underpinnings of wildlife management and to apply evolving ecological concepts to changes and adaptations in management practices. Gathering many of the best and greatest minds in wildlife science, this volume addresses the critically important theme of linking ecological theory and management applications. Divided into five parts, the first two parts deal with the landscape ecology of birds and mammals respectively, demonstrating the need for applied theory in gamebird management and the preservation of the cougar. Part three highlights the role of climate when applying ecological theory to habitat management and discusses the emergence of ecosystem management in managing wildlife at the ecosystem scale. Part four considers the management of wildlife disease and reveals the increasing importance of genetics in conservation and ecology. Finally, the economic and social issues affecting wildlife science round out the coverage in part five. Applying emerging ecological theory for the advancement of wildlife management, Wildlife Science: Linking Ecological Theory and Management Applications provides a long awaited cooperative look at the future of ecosystem management.

Invasion ecology is the study of the causes and consequences of the introduction of organisms to areas outside their native range. Interest in this field has exploded in the past few decades. Explaining why and how organisms are moved around the world, how and why some become established and invade, and how best to manage invasive species in the face of global change are all crucial issues that interest biogeographers, ecologists and environmental managers in all parts of the world. This book brings together the insights of more than 50 authors to examine the origins, foundations, current dimensions and potential trajectories of invasion ecology. It revisits key tenets of the foundations of invasion ecology, including contributions of pioneering naturalists of the 19th century, including Charles Darwin and British ecologist Charles Elton, whose 1958 monograph on invasive species is widely acknowledged as having focussed scientific attention on biological invasions.
