Book Description
Dragonflies are among the most familiar and popular of all insects, deeply embedded in human cultural history. They are iconic and tell us much about the environments in which we and they live. Their conservation is an important part of biodiversity conservation. One modern dragonfly species is listed as extinct, with many others currently threatened. It is now essential to increase conservation efforts towards saving these threatened species, with strategies now available for doing this. Recovery of dragonfly populations goes hand in hand with improvements to both freshwater conditions and bank vegetation quality. In contrast, some other dragonfly species have benefitted greatly from human transformation of the landscape, with artificial ponds in particular, increasing the population levels of many species. In turn, climate change is seeing many geographical range shifts. Conservation of Dragonflies: Sentinels for Freshwater Conservation is for naturalists, citizen scientists, entomologists and conservation scientists, as well as practitioners and policy makers around the world.

Book Description
The Yungas are highly biodiverse cloud forests extending from Venezuela south through NW Argentina, and are considered one of the biodiversity 'hot spots' in South America. This bilingual (Spanish/English) pocket field guide, the first of its kind for any region in South America, is accompanied by 280 illustrations including detailed diagnostic drawings and numerous color photos of live dragonflies. It covers all 102 species in 45 genera and 9 families found in the Argentine Yungas, representing over a third of all species known from the country. This guide provides a reliable and original means of identifying adult odonates for limnologists, ecologists, biologists, naturalists, amateurs and to anyone interested in the aquatic ecosystems of the cloud forests of the South American Andes, their biota and conservation. Natalia von Ellenrieder is a researcher for the CONICET (Consejo de Investigaciones Cientificas y Tecnicas) at the Instituto de Bio y Geociencias in Salta, Argentina, and Rosser W. Garrison is an Insect biosystematist at the California Department of Food and Agriculture in the US.

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.

Book Description
Ecologists have long struggled to predict features of ecological systems, such as the numbers and diversity of organisms. The wide range of body sizes in ecological communities, from tiny microbes to large animals and plants, is emerging as the key to prediction. Based on the relationship between body size and features such as biological rates, the physics of water and the amount of habitat available, we may be able to understand patterns of abundance and diversity, biogeography, interactions in food webs and the impact of fishing, adding up to a potential 'periodic table' for ecology. Remarkable progress on the unravelling, describing and modelling of aquatic food webs, revealing the fundamental role of body size, makes a book emphasising marine and freshwater ecosystems particularly apt. In this 2007 book, the importance of body size is examined at a range of scales that will be of interest to professional ecologists, from students to senior researchers.

Book Description
Climate change has been a central concern over recent years, with visible and highly publicized consequences such as melting Arctic ice and mountain glaciers, rising sea levels, and the submersion of low-lying coastal areas during mid-latitude and tropical cyclones. This book presents a review of the spatial impacts of contemporary climate change, with a focus on a systematic, multi-scalar approach. Beyond the facts – rises in temperature, changes in the spatial distribution of precipitation, melting of the marine and terrestrial cryosphere, changes in hydrological regimes at high and medium latitudes, etc. – it also analyzes the geopolitical consequences in the Arctic and Central Asia, changes to Mediterranean culture and to viticulture on a global scale, as well as impacts on the distribution of life, for example, in the Amazon rainforest, in large biomes on a global scale, and for birds.

Book Description
Methods in Stream Ecology, Second Edition, provides a complete series of field and laboratory protocols in stream ecology that are ideal for teaching or conducting research. This updated edition reflects recent advances in the technology associated with ecological assessment of streams, including remote sensing. In addition, the relationship between stream flow and alluviation has been added, and a new chapter on riparian zones is also included. The book features exercises in each chapter; detailed instructions, illustrations, formulae, and data sheets for in-field research for students; and taxanomic keys to common stream invertebrates and algae. With a student-friendly price, this book is key for all students and researchers in stream and freshwater ecology, freshwater biology, marine ecology, and river ecology. This text is also supportive as a supplementary text for courses in watershed ecology/science, hydrology, fluvial geomorphology, and landscape ecology. - Exercises in each chapter - Detailed instructions, illustrations, formulae, and data sheets for in-field research for students - Taxanomic keys to common stream invertebrates and algae - Link from Chapter 22: FISH COMMUNITY COMPOSITION to an interactive program for assessing and modeling fish numbers

Book Description
The family Bulimulidae is a dominant land snail family in the Neotropics, with more than 1000 nominal taxa described. Revisionary work has only partially been done, but many genera need further revisionary work for which a sound taxonomic basis is needed. Type specimens for more than 400 taxa of this family are present in the Natural History Museum, London, U.K., and are documented in this paper. For each taxon the relevant literature is cited, type locality, label, the provenance of the specimens, and the current systematic position; photographs of nearly all type specimens and labels are also provided.
