Leaf beetles are one of the largest groups of beetles, with tens of thousands of species worldwide and around 280 in Britain. They belong mainly to the family Chrysomelidae, but also to two small closely related families, the Megalopodidae and Orsodacnidae. This book provides a comprehensive overview with detailed and accessible coverage of the natural history, ecology and biology of leaf beetles. Topics cover the life history of leaf beetles, biology, their environment, natural enemies and interactions with humans. There is a thorough discussion about identification of British species, including detail on the juvenile stages (eggs, larvae, pupae) and a concise key to adults. A chapter is dedicated to study techniques and materials. The book is illustrated throughout with colour photographs and line drawings. Leaf beetles is a vital resource for entomology students and educators, naturalists, nature conservationists, those involved in agriculture, horticulture and the management of stored produce.

Offers a comprehensive, accessible introduction to experimental design, field monitoring skills for plants and animals, data analysis, interpretation and reporting This user-friendly book presents field monitoring skills for both plants and animals, within the context of a research project. This text provides a single resource to take the reader all the way through from the planning stage, into the field, guiding through sampling, organism identification, computer-based data analysis and interpretation, and finally how to present the results to maximise the impact of the work. Logically structured throughout, and revised extensively in the second edition, the book concentrates on the techniques required to design a field-based ecological survey and shows how to execute an appropriate sampling regime. It evaluates appropriate sampling and analytical methods, identifying potential problems associated with various techniques and how to mitigate these. The second edition of this popular text has updated reference material and weblinks, increased the number of case studies by 50% to illustrate the use of specific techniques in the field, added over 20% more figures (including 8 colour plates), and made more extensive use of footnotes to provide extra details. Extensions to topics covered in the first edition include additional discussion of: ethical issues; statistical methods (sample size estimation, use of the statistical package R, mixed models); bioindicators, especially for freshwater pollution; seeds, fecundity and population dynamics including static and dynamic life tables; forestry techniques including tree coring and tree mortality calculations; the use of data repositories; writing for a journal and producing poster and oral presentations. In addition, the use of new and emerging technologies has been a particular focus, including mobile apps for environmental monitoring and identification; land cover and GIS; the use of drones including legal frameworks and codes of practice; molecular field techniques including DNA analysis in the field (including eDNA); photo-matching for identifying individuals; camera trapping; modern techniques for detecting and analysing bat echolocation calls; and data storage using the cloud. Divided into six distinct chapters, Practical Field Ecology, 2nd Edition begins at project inception with a chapter on planning—covering health and safety, along with guidance on how to ensure that the sampling and experimental design is suitable for subsequent statistical analysis. Following a chapter dealing with site characterisation and general aspects of species identification, subsequent chapters describe the techniques used to survey and census particular groups of organisms. The final chapters cover analysing, interpreting and presenting data, and writing up the research. Offers a readable and approachable integrated guide devoted to field-based research projects Takes students from the planning stage, into the field, and clearly guides them through organism identification in the laboratory and computer-based data analysis, interpretation and data presentation Includes a chapter on how to write project reports and present findings in a variety of formats to differing audiences Aimed at undergraduates taking courses in Ecology, Biology, Geography, and Environmental Science, Practical Field Ecology, 2nd Edition will also benefit postgraduates seeking to support their projects.

In the early Middle Ages, a network of maritime trading towns – emporia – emerged along the northern coasts of Europe. These early urban sites are among archaeology’s most notable contributions to our knowledge of the period between the disintegration of the Western Roman Empire and the growth of a maritime-oriented world in the Viking Age. Ribe, on the western coast of Denmark, is one of these sites. In 2017-18 the Northern Emporium research project conducted seminal research excavations, which provided new foundations for the study of this nodal point between Western Europe, Scandinavia, and the world beyond. This first volume presents the results of these excavations and analyses to piece together the history of the emporium and its social fabric. The research employs novel, high-definition methods to explore the networks of the site, integrating an extensive use of geoarchaeology and 3D stratigraphic recording with intensive environmental sampling and artefact recovery, resulting in more than 100,000 artefact finds. The results transform our understanding of key points of the early history of the North Sea region. Through the remains of dwellings and workshops – the traces left by traders, sailors, weavers, tailors, comb makers, and skilled producers of glass beads and metal ornaments – we follow the creation of Viking Age social networks, along with some of the most iconic artistic products of this world and the daily lives of some of its notable inhabitants.

Adults of the Orsodacnidae and Chrysomelidae, including Bruchinae, from South Carolina are keyed and described. These leaf beetles and seed weevils total 498 species in 139 genera that have been reported from or are likely to occur in the state. Included are diagnostic keys and diagrams to aid in identification, a photograph of one species from each genus, data on range both in South Carolina and in North America, months of collection of adults in South Carolina, and host plants. Fifty-one new state records are noted. - from the National History Book Service.

This volume contains richly illustrated keys and descriptions of the 157 species of predaceous diving beetles (Dytiscidae) found in Fennoscandia, Denmark and the Baltic States. Information about biology and distribution is included, as is a catalogue of provincial records.
