Book Description

Following the publication of C. S. Holling's seminal work on the relationship between animal body mass patterns and scale-specific landscape structure, ecologists began to explore the theoretical and applied consequences of discontinuities in ecosystems and other complex systems. Are ecosystems and their components continuously distributed and do they adhere to scaling laws, or are they discontinuous and more complex than early models would have us believe? The resulting propositions over the structure of complex systems sparked an ongoing debate regarding the mechanisms generating discontinuities and the statistical methods used for their detection. This volume takes the view that ecosystems and other complex systems are inherently discontinuous and that such fields as ecology, economics, and urban studies greatly benefit from this paradigm shift. Contributors present evidence of the ubiquity of discontinuous distributions in ecological and social systems and how their analysis provides insight into complex phenomena. The book is divided into three sections. The first focuses on background material and contrasting views concerning the discontinuous organization of complex systems. The second discusses discontinuous patterns detected in a number of different systems and methods for detecting them, and the third touches on the potential significance of discontinuities in complex systems. Science is still dominated by a focus on power laws, but the contributors to this volume are convinced power laws often mask the interesting dynamics of systems and that those dynamics are best revealed by investigating deviations from assumed power law distributions. In 2008, a grand conference on resilience was held in Stockholm, hosting 600 participants from around the world. There are now three big centers established with resilience, the most recent one being the Stockholm Resilience Center, with others in Australia (an international coral reef center), Arizona State University's new sustainability center focusing on anthropology, and Canada's emerging social sciences and resilience center. Activity continues to flourish in Alaska, South Africa, and the Untied Kingdom, and a new center is forming in Uruguay.

Book Description

Walking a forest trail in Costa Rica, a visitor might be struck by the sight of an iridescent blue morpho butterfly fluttering ahead in the filtered daylight, or an enormous silk moth, as magnificently patterned and subtly colored as a Persian carpet, only emerging to fly at night. Elsewhere, vivid yellow and orange sulphur butterflies flock to puddles to sip the concentrated minerals. Such is the dazzling variety of the butterflies and moths unique to this region. Gathered by biologists Daniel Janzen and Winifred Hallwachs in the forests of northwestern Costa Rica, 100 tropical butterflies and moths represent the diversity in large-format photographs by Jeffrey Miller that document the dizzying variety of shapes, colors, and markings. The photographs are accompanied by species accounts and images of the corresponding caterpillar. The authors recount these insects' feats of mimicry and migration, lift the veil on their courtship, and show how the new technology of DNA barcoding is changing the picture of Lepidopteran biodiversity. The authors also tell the success story of Area de Conservacion Guanacaste, where the long-term work of Janzen and Hallwachs, a team of caterpillar collectors, and the participation of neighboring farming communities has deepened understanding of Costa Rica's Lepidoptera and has brought about advances in restoration ecology of tropical habitats, biodiversity prospecting, biotechnology, and ecotourism development.

Book Description

Certificate of Commendation Winner at the 2001 Whitley Awards - Best Zoological Reference Section This very detailed compendium of data on taxonomy and nomenclature of Australian butterflies is another in the Catalogue series produced by the Australian Biological Resources Study, a sub-program of Environment Australia. Expanding on the butterfly section of the earlier Checklist of the Lepidoptera of Australia by Nielsen, Edwards & Rangsi (1996) This Catalogue contains the fine details of naming and status of types of Australian butterflies, and information critical for fixing the scientific names of the species. This volume is the 'Who's Who' for the Australian butterfly fauna, the very basic information we all need, but find so difficult to access and evaluate for ourselves. It is introduced by a comprehensive historical and explanatory account of work on Australian butterflies. Details are given of all genus and species synonymies applicable to the Australian fauna. There are details of the type designations of all 507 available generic names, of type data for the 1,004 available species group names and of nomenclatural changes and changes in taxonomic status for most of the 136 valid genera, 400 species, and 371 subspecies. The butterflies have an enormous literature and this catalogue provides a guide to the significant literature of each taxon. An extensive list of larval food plants is also included, as well as succinct information on ecology and distribution and a comprehensive bibliography. Features

Book Description

A short hike through an Indiana forest reveals layers of living things: the overstories and understories of trees, the shadow of a mammal, colorful fungi. But what would it mean to methodically document the communities of plants and animals harboring in Indiana's public forests, at humid midnight or coldest dawn? What is the impact of this wondrous knowledge? Ecoblitz describes the findings of, and the dogged scientists behind, the Indiana Forest Alliance's multiyear forest wildlife census. Scientists' journeys in pursuit of elusive bats, lavish lichen, and spider species paint a breathtaking picture of Indiana's biodiversity and its value to Indiana's policy, polity, and poetics. This book will amaze readers with a dazzling portrait of local biodiversity, deepen appreciation for Indiana's eastern hardwood forest system, and inspire a desire to advocate for it. Ecoblitz is a book for lovers of nature, for those who appreciate science but are not scientists themselves, and for those who want to learn something new.

Book Description

Through its geographical position, varied topography, particular climate and complex cultural history, Romania has managed to sustain enormously rich biodiversity. Traditional practices, which have survived longer than in most other parts of Europe, have allowed the preservation of large areas of natural habitat, little altered by human activity. All this is reflected in the breadth of lepidoptera encountered in the country – from the dazzling Freyer’s Purple Emperor to the elusive Moorland Clouded Yellow, from the almost bird-like Great Banded Grayling to the diminutive Osiris Blue. This book considers all the species (and subspecies) of butterflies known to occur in Romania. This identification guide to the butterflies of Romania is set out in a format easy to understand not only by specialists but also for the more general naturalist or butterfly enthusiast. An expansive introduction covers the various life stages (ovum, larva, pupa and imago), biology and ecology, as well as protection and conservation, and butterfly research. The next section identifies the 14 most important habitat types frequented by butterflies in Romania. For each of the more than 200 species covered, information on taxonomy, identification, habitat, biology, conservation and distribution is presented. Each is illustrated with photographs from nature, primarily adult males and females, but also numerous images of the developmental stages. There follows a complete set of plates of prepared butterflies, displaying dorsal and ventral positions (upper and undersides) for both males and females. Finally, the male genital armature of several species are illustrated, primarily those difficult or impossible to identify using visual determination. The result is an attractive, practical and portable guide that not only helps identify the butterfly species of Romania, but also encourages the reader to more fully appreciate and protect them.

Book Description

Islands are special places; they can be havens for unique plants and animals and refuges for wildlife. This book investigates the biogeography of butterfly species over the British islands, particularly the factors that influence their presence on the islands and that have made each island's butterfly fauna distinctive. The book contains a full log of records of species on the islands and much supporting information. The first three chapters set the scene, illustrating the basics of island biogeography theory, their changing circumstances during the current Holocene interglacial, and studies of natural history of British butterflies that mark the islands as the most intensively studied region for wildlife in the world. The book advances by increasing resolution downscale from a European continental perspective, through patterns and changes on the British mainland, a comparison of the two dominant islands of Britain and Ireland, to a close inspection of the dynamics of species on the multitude of offshore islands. Detailed investigations include contrasts in species' richness on the islands and then of the incidences of each species. Case studies highlight the continual turnover of species on islands. Attention is then given to evolutionary changes since the time that glaciers enveloped Europe. A powerful message is conveyed for the maintenance of butterfly species on the smaller British islands now experiencing population losses at a rate unprecedented since the spread of the last ice sheets: the incontrovertible importance of maintaining populations of species on nearby mainland sources for islands as pools for future migrants.
