Book Description
Winner of the Marsh Book of the Year Award 2012 by theBritish Ecological Society. In A Resource-Based Habitat View for Conservation RogerDennis introduces a novel approach to the understanding of habitatsbased on resources and conditions required by organisms and theiraccess to them, a quantum shift from simplistic andineffectual notions of habitats as vegetation units or biotopes. Indrawing attention to what organisms actually use and need inlandscapes, it focuses on resource composition, structure andconnectedness, all of which describe habitat quality and underpinlandscape heterogeneity. This contrasts with the current bipolarview of landscapes made up of habitat patches and empty matrix butillustrates how such a metapopulation approach of isolatedpatchworks can grow by adopting the new habitat viewpoint. The book explores principles underlying this newdefinition of habitat, and the impact of habitat components onpopulations, species’ distributions, geographical ranges andrange changes, with a view to conserving resources in landscapesfor whole communities. It does this using the example ofbutterflies - the most alluring of insects, flagship organisms andkey indicators of environmental health - in the British Isles,where they have been studied most intensively. The book formsessential reading for students, researchers and practitioners inecology and conservation, particularly those concerned withmanaging sites and landscapes for wildlife.

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.

Book Description
Insects display a staggering diversity of behaviors. Studying these systems provides insights into a wide range of ecological, evolutionary, and behavioral questions including the genetics of behavior, phenotypic plasticity, chemical communication, and the evolution of life-history traits. This accessible text offers a new approach that provides the reader with the necessary theoretical and conceptual foundations, at different hierarchical levels, to understand insect behavior. The book is divided into three main sections: mechanisms, ecological and evolutionary consequences, and applied issues. The final section places the preceding chapters within a framework of current threats to human survival - climate change, disease, and food security - before providing suggestions and insights as to how we can utilize an understanding of insect behavior to control and/or ameliorate them. Each chapter provides a concise, authoritative review of the conceptual, theoretical, and methodological foundations of each topic.

Book Description
In Loe Bar and the Sandhill Rustic Moth, Adrian Spalding examines the survival of plants and animals on Loe Bar, a shingle beach on the coast of Cornwall, in the context of its history, geomorphology and exposure to the Atlantic environment. He develops these themes within a detailed study of the Sandhill Rustic moth that endures this harsh environment where storm surges, high salinity, high temperatures, strong winds and burial by sand affect the wildlife that occurs there.

Book Description
Some European lands have been progressively alleviated of human pressures, particularly traditional agriculture in remote areas. This book proposes that this land abandonment can be seen as an opportunity to restore natural ecosystems via rewilding. We define rewilding as the passive management of ecological successions having in mind the long-term goal of restoring natural ecosystem processes. The book aims at introducing the concept of rewilding to scientists, students and practitioners. The first part presents the theory of rewilding in the European context. The second part of the book directly addresses the link between rewilding, biodiversity, and habitats. The third and last part is dedicated to practical aspects of the implementation of rewilding as a land management option. We believe that this book will both set the basis for future research on rewilding and help practitioners think about how rewilding can take place in areas under their management.

Book Description
Hedges and field margins are important wildlife habitats and deliver a range of ecosystem services, and their value is increasingly recognised by ecologists. This book reviews and assesses the current state of research on hedgerows and associated field margins. With the intensification of agriculture in the second half of the last century, field sizes were increased by amalgamation and the rooting out of hedges, synthetic pesticide and inorganic fertiliser use increased, and traditional methods of hedge management were largely abandoned. The book is split into two main sections. The first deals with definitions, current and historic management, the impact of pesticides, the decline in hedge stock and condition, and new approaches to hedge evaluation using remote sensing techniques. The second section explores the pollination and biological pest control benefits provided by hedges and field margins and examines the ecology of some of the major groups that are found in hedgerows and field margins: butterflies and moths, carabid beetles, mammals, and birds. A case study on birds and invertebrates from a research farm managed as a commercial enterprise, but which attempts to farm with wildlife in mind, brings these themes together. A final chapter introduces the neglected area of hedges in the urban environment. The book will be of great interest to advanced students, researchers and professionals in ecology, agriculture, wildlife conservation, natural history, landscape, environmental and land management.

Book Description
In Butterfly Biology Systems Roger Dennis explores key topics and contentious issues in butterfly biology, specifically those in life history and behaviour. Uniquely, using a systems approach, the book focuses on the degree of integration and feedback between components and elements affecting each issue, as well as the links between different issues. The book comprises four sections. The first two sections introduce the reader to principles and approaches for investigating complex relationships, and provide a platform of knowledge on butterfly biology. The final two sections deal in turn with life history and behaviour, covering key issues affecting different stages of development from eggs to adults.

Book Description
This book summarises decades of research and collation of distributional data. From the tiny Freyeria trochylus (Grass Jewel), Europe's smallest butterfly, to the magnificent, newly arrived Papilio demoleus (Lime Swallowtail), this comprehensively illustrated reference book and field guide includes all butterfly species known in Cyprus over the past 100 years. Where applicable, reference is made to subspecies of related taxa present in nearby countries of the eastern Mediterranean. The images on the cover represent the island's seven endemics, discussed in depth. Included, too, are detailed distribution maps representing records garnered from almost 300 recorders/sources (particularly members of the Cyprus Butterfly Study Group), over a period of more than 20 years.

Book Description
Inchworms, tiger moths, underwings, owlet moths, silkworms,sphinx moths, grass moths, and butterflies. Collectively, these and many others are the Lepidoptera, one of the most diverse groups of animals on the planet. Lepidoptera can be found in the highest tropical canopies,the driest deserts, and at the leading edge of science. The adults include some of the most beautiful insects that have inspired artists and have sailed through the dreams of human cultures for millennia. The immature stages (“caterpillars”), like the underwing depicted on the cover, link together vital processes in diverse terrestrial ecosystems that are only barely documented let alone understood. The people that study these animals are lepidopterists, and the goal of this book is to introduce them with their own words. In twenty chapters, lepidopterists tell their stories, and these tales mirror the diversity of nature in their range and depth. You will find individuals that wrestle with the challenges of scientific careers, stories of far flung travel sand close calls, and historical perspectives on recent decades of scientific break throughs.

Book Description
The book introduces basic entomology, emphasising perspectives on insect diversity important in conservation assessment and setting priorities for management, as a foundation for managers and others without entomological training or background. It bridges the gap between photographic essays on insect identification and more technical texts, to illustrate and discuss many aspects of taxonomic, ecological and evolutionary diversity in the Australian insect fauna, and its impacts in human life, through outlines of many aspects of insect natural history.
