Dragonflies at a Biogeographical Crossroads
Author: Brenda D. SmithPublisher: CRC Press
ISBN: 1000056333
Category : Nature
Languages : en
Pages : 724
Book Description
This lavishly illustrated book examines the distribution, ecology, conservation status, and biogeography of 176 species of dragonflies in the southern plains of the United States, where twelve ecoregions converge. The topics discussed, such as phenotypic variation and ecology, are applicable and of interest across the United States and much of north America, and will appeal to researchers and dragonfly enthusiasts alike. A series of maps, including a distributional map by specific locality of occurrence, indicate level of documentation and allow the reader to visualize the biogeographical associations of a given species. These maps also encourage citizen scientists to contribute documentation wherever they spend time in the field. Context-driven chapters, including one on the region’s rich paleontological history, blend environmental history and biogeography, giving the book a fresh perspective on the natural world while providing a rich summary of the odonates. Dragonflies at a Biographical Crossroads: The Odonata of Oklahoma and Complexities Beyond Its Borders will be sought out by dragonfly researchers and enthusiasts, entomologists, amateur naturalists, paleontologists, conservation biologists, educators, regional historians, and those seeking to meld the disciplines of cultural and environmental history with biology. It will also be readily accessible to the lay public. Dragonflies combine the visually stunning with acrobatic fireworks in ways no other insect can hope to combine.
Dragonflies and Damselflies of South Africa

Book Description
Dragonflies are a beautiful, important and conspicuous component of freshwater, whether still or flowing. South Africa's dragonflies are particularly interesting as many are special or endemic to the area, making it a part of the world of great conservation significance. This book discusses this exciting dragonfly fauna. Dragonflies are a beautiful, important and conspicuous component of freshwater, whether still or flowing. They are also important indicators of freshwater quality and condition, which is significant for current and future conservation initiatives in South Africa. The country's dragonflies are particularly interesting as many are special or endemic to the area, making it a part of the world of great conservation significance. Sadly however, many of these endemic species are highly threatened, especially by invasive alien trees which shade out their habitat. This book is about this exciting dragonfly fauna. Besides aiming at increasing awareness of these lovely and sensitive insects, it enables their identification, using several approaches, from simple flick-through to the use of comprehensive identification keys. Each species is also given a Dragonfly Biotic Index, covering a spectrum from the most common, widespread and tolerant species through to the most threatened, rare and sensitive ones. Michael Samways is Professor and Chair of the Department of Conservation Ecology and Entomology, Stellenbosch University. He is a Fellow of the Royal Society of South Africa and a Fellow of the University of KwaZulu-Natal. He has published 260 scientific papers and written several books on insect biology and conservation, the most recent of which is Insect Diversity Conservation, Cambridge University Press. He has won several awards, and in the last two years, these include the Stellenbosch University Rector's Award for Research Excellence, the John Herschel Medal from the Royal Society of South Africa, and the Senior Captain Scott Medal from the South African Academy for Science and Art. Michael is on several international editorial boards and involved with various international committees devoted to invertebrate conservation. Indeed, his research team is dedicated to the conservation of invertebrates and other biodiversity, which so enrich our planet.

The Status and Distribution of Dragonflies of the Mediterranean Basin

Author: Fred SibleyPublisher: Lulu.com
ISBN: 1609621611
Category : Science
Languages : en
Pages : 102
Book Description
The Nebraska odonate list has 109 species in two suborders, damselflies (Zygoptera) with 47 species and dragonflies (Anisoptera) with 62 species. Nebraska had been very poorly surveyed prior to 2005 and 63 counties had fewer than 10 records. By 2017 the number of county records had nearly quadrupled, to over 3000 records, the average county total had increased from 9 to 33 and all counties had at least 21 records. An effort was made to collect data more or less uniformly from all 93 Nebraska counties. The areas with intense corn and soybean farming, eastern and southcentral areas, are low in diversity (21-30 species per county), the southeast and western half of the state are higher (31-40 species) and the northwestern and northern Sandhill counties are the richest with more than 50 species per county. The present state list of 109 species represents 12 additions since 1998. Eleven additional species have been reported from the state, but are considered invalid or have been re-identified. This paper presents a short history of odonate study in Nebraska and an analysis of the data for the 109 species recorded in Nebraska to date. Distribution maps by county are included for each identified
