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.
Conservation interest in moths, by far the predominant components of Lepidoptera, lags far behind that for butterflies, for which conservation practice provides many well-established lessons for extension to their near relatives. The needs of moths are at least as great, but their greater richness and variety, and far poorer documentation of diversity and biology over much of the world contribute to this lack of attention. Australia’s rich moth fauna, largely endemic and of global interest, illustrates many of the problems of developing wider interest and support for moth conservation. Numerous species (perhaps half the total fauna) are undescribed, and many are ecological specialists in restricted and vulnerable environments over small parts of the continent. Establishing their conservation status and needs whilst accepting that foundation knowledge is highly incomplete and much species-focused conservation is impracticable provides complex problems in setting priorities, based largely on wider diversity and effective advocacy. Most Australian vegetation systems, from grassland to forest and from sea-level to alpine zones, have been eroded in extent and quality since European settlement, resulting in massive habitat changes for native insects and to leave fragmented (and commonly degraded) remnants in which moths and others may persist. Recent surveys continue to increase recorded moth richness, reveal local faunal peculiarities, and indicate how assemblage changes may mirror wider environmental changes. This book is an overview of advances in documenting and interpreting moth diversity and ecology, to show how information from better-studied moth faunas can help in planning conservation of Australia’s moths through measures such as understanding the moths themselves by increased surveys and study, the factors influencing their diversity and wellbeing, and how such threats may be countered through increased coordinated conservation interest, commitment and management.
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.
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.
This publication is a celebration of the natural history of Cornwall and the Isles of Scilly, featuring 40 sites where flora and fauna may be seen in a variety of habitats, suggested walks, and some 580 species.
This volume completes the survey of the ca. 400 species of springtails, which can be found in Finland, Sweden, Norway, Denmark, Iceland, the Faroes and the Arctic Islands and includes the sections Entomobryomorpha and Symphypleona. The first volume, published in 1998, covered Poduromorpha. Identification keys and full descriptions of the species are richly illustrated by line drawings. Photos are provided for some species displaying characteristic patterns of pigmentation. New diagnostic characters, including sensillary chaetotaxy and details of the mouth apparatus, are introduced. With the appearence of this book soil scientists and the interested amateur have now a modern tool to identify all species of Nordic springtails. In addition the habitat preferences and geographical distribuition are summarised. The book will be of general interest to everyone working on springtail identification.
