Available in PDF, EPUB and Kindle. Book excerpt: Hymenoptera, the bees, wasps and ant, are one of the largest insect orders, and have massive ecological importance as pollinators and as predators or parasitoids of other insects. These roles have brought them forcefully to human notice , as governors of some key ecological services that strongly influence human food supply. Recent declines of pollinators and introductions of alien pests or biological control agents are only part of the current concerns for conservation of Hymenoptera, and of the interactions in which they participate in almost all terrestrial ecosystems. Both pests and beneficial species abound within the order, sometimes closely related within the same families. Many taxa are both difficult to identify, and very poorly known. This global overview, the first such account for the whole of the Hymenoptera, discusses a broad range of themes to introduce the insects and their conservation roles and needs, and how their wellbeing may be approached. The book is intended as a source of information for research workers, students, conservation managers and naturalists as an introduction to the importance of this dominant insect order.

Book excerpt: This book brings together scientific evidence and experience relevant to the practical conservation of wild bees. The authors worked with an international group of bee experts and conservationists to develop a global list of interventions that could benefit wild bees. They range from protecting natural habitat to controlling disease in commercial bumblebee colonies. For each intervention, the book summarises studies captured by the Conservation Evidence project, where that intervention has been tested and its effects on bees quantified. The result is a thorough guide to what is known, or not known, about the effectiveness of bee conservation actions throughout the world. Bee Conservation is the first in a series of synopses that will cover different species groups and habitats, gradually building into a comprehensive summary of evidence on the effects of conservation interventions for all biodiversity throughout the world. By making evidence accessible in this way, we hope to enable a change in the practice of conservation, so it can become more evidence-based. We also aim to highlight where there are gaps in knowledge. Evidence from all around the world is included. If there appears to be a bias towards evidence from northern European or North American temperate environments, this reflects a current bias in the published research that is available to us. Conservation interventions are grouped primarily according to the relevant direct threats, as defined in the International Union for the Conservation of Nature (IUCN)’s Unified Classification of Direct Threats.

Available in PDF, EPUB and Kindle. Book excerpt: The third in a trilogy of global overviews of conservation of diverse and ecologically important insect groups. The first two were Beetles in Conservation (2010) and Hymenoptera and Conservation (2012). Each has different priorities and emphases that collectively summarise much of the progress and purpose of invertebrate conservation. Much of the foundation of insect conservation has been built on concerns for Lepidoptera, particularly butterflies as the most popular and best studied of all insect groups. The long-accepted worth of butterflies for conservation has led to elucidation of much of the current rationale of insect species conservation, and to definition and management of their critical resources, with attention to the intensively documented British fauna ‘leading the world’ in this endeavour. In Lepidoptera and Conservation, various themes are treated through relevant examples and case histories, and sufficient background given to enable non-specialist access. Intended for not only entomologists but conservation managers and naturalists due to its readable approach to the subject.

Download or read book Hymenoptera and Biodiversity written by John LaSalle and published by Oxford University Press, USA. This book was released on 1993 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing attention has been focused on biodiversity in recent years, based on a number of arguments to justify the conservation of the world's flora and fauna. Such arguments may be economic - that species may have potential for food or medicine - or ecological - that the extinction of any species affects the overall ecological balance. Little attention, however, has been focused on which groups have the greatest impact on maintaining diversity. Hymenoptera is one of these groups. It not only forms a major component of diversity itself, but is vital in sustaining diversity in other groups. Hymenoptera species (bees, wasps, ants and sawflies) are major plant pollinators, seed dispersers and parasitoids and predators of other arthropods (and hence important in biological control). This volume therefore tackles an important subject and concentrates on three key issues: how species of Hymenoptera affect diversity in other organisms; whether Hymenoptera is a group prone to extinction; and the consequences if Hymenoptera species are differentially removed from terrestrial ecosystems. The book is essential reading for entomologists and those concerned with biodiversity and conservation.

Available in PDF, EPUB and Kindle. Book excerpt: The Conservation of Insects and their Habitats is a compilation of papers presented in the 15th Symposium of the Royal Entomological Society of London held at the Department of Physics Lecture Theatre Imperial College, London, on September 14-15, 1989. The papers cover topics on the diversity of entomological habitats and ecologicalroles around the world, and highlight the value of insects to humanity. Some practical proposals for conservation, especially in tropical forests and on islands, where their diversity is greatest, are also given. This book will add to the continuing force for the conservation and protection of biological diversity of the Earth.

This book was released on 1993 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is the result of a course on identification of Hymenoptera given three times since 1985 at the Centre for Land and Biological Resources Research. The considerable interest in these courses indicated the need for a comprehensive identification guide to all extant families of Hymenoptera. The main emphasis is on family identification using the keys, which are complemented by family sketches. The sketches include a taxonomic diagnosis to supplement the keys, a summary of the biology, the size and distribution, and important literature references.
Download or read book Insects Fire and Conservation written by Tim R. New and published by Springer. This book was released on 2014-09-03 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: A global synthesis of the impacts of wildfires and controlled burning on insects, bringing together much hitherto scattered information to provide a guide to improved conservation management practice. The great variety of responses by insect species and assemblages demonstrates the often subtle balance between fire being a severe threat and a vital management component. Examples from many parts of the world and from diverse biotopes and production systems display the increasingly detailed appreciation of fire impacts on insects in terrestrial and freshwater environments and the ways in which prescribed burning may be tailored to reduce harmful ecological impacts and incorporated into protocols for threatened species and wider insect conservation benefits.
Download or read book Insect Conservation and Urban Environments written by Tim R. New and published by Springer. This book was released on 2015-09-18 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Includes chapters on assessing changes among assemblages and in individual species, the variety of general threats (notably habitat changes and impacts of alien species) and more particularly urban threats. The first global overview and synthesis of the impacts of urbanisation on insects and their relatives and the needs and theoretical and practical background to conserving them in urban environments. Insect dependence on open spaces in built-up areas suggests a wide range of management options for conservation, from individual site (including novel habitats such as green roofs) to landscape-level connectivity. These measures, all discussed with specific examples, involve all sectors of humanity, from government agencies to individual householders and ‘citizen scientist’ groups. Each chapter includes pertinent and recent.

Download or read book Saproxylic Insects written by Michael D. Ulyshen and published by Springer. This book was released on 2018-05-21 with total page 904 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers extensive information on insect life in dying and dead wood. Written and reviewed by leading experts from around the world, the twenty-five chapters included here provide the most global coverage possible and specifically address less-studied taxa and topics. An overarching goal of this work is to unite literature that has become fragmented along taxonomic and geographic lines. A particular effort was made to recognize the dominant roles that social insects (e.g., termites, ants and passalid beetles) play in saproxylic assemblages in many parts of the world without overlooking the non-social members of these communities. The book is divided into four parts: · Part I “Diversity” includes chapters addressing the major orders of saproxylic insects (Coleoptera, Diptera, Hymenoptera, Hemiptera, Lepidoptera and Blattodea), broadly organized in decreasing order of estimated global saproxylic diversity. In addition to order-level treatments, some chapters in this part discuss groups of particular interest, including pollinators, hymenopteran parasitoids, ants, stag and passalid beetles, and wood-feeding termites. · Part II “Ecology” discusses insect-fungal and insect-insect interactions, nutritional ecology, dispersal, seasonality, and vertical stratification. · Part III “Conservation” focuses on the importance of primary forests for saproxylic insects, offers recommendations for conserving these organisms in managed forests, discusses the relationships between saproxylic insects and fire, and addresses the value of tree hollows and highly-decomposed wood for saproxylic insects. Utilization of non-native wood by saproxylic insects and the suitability of urban environments for these organisms are also covered. · Lastly, Part IV “Methodological Advancements” highlights molecular tools for assessing saproxylic diversity. The book offers an accessible and insightful resource for natural historians of all kinds and will especially appeal to entomologists, ecologists, conservationists and foresters.
