Ladybirds are probably the best known predators of aphids and coccids in the world, though this greatly underestimates the diversity of their biology. Maximising their impact on their prey is an important element in modern conservation biological control of indigenous natural enemies in contrast to the classical approach of releasing alien species. Ivo Hodek is one of the most internationally respected experts on coccinellids who has researched these insects for his entire career. He has now brought together 14 scientists of international standing to author 12 chapters, making this book the definitive treatment of coccinellid biology and ecology. This volume covers the rapid scientific developments of recent years in the understanding of coccinellid phylogeny, the semiochemicals influencing their behaviour and of molecular genetics. Recent insights in relation to intraguild predation and the assessment of the predatory impact of coccinellids are also covered. Other special features of the volume are the extensive references covering the literature from both East and West and a taxonomic glossary of the up-to-date nomenclature for species of coccinellids as well as of other organisms mentioned in the text. While aimed at researchers, university teachers and agricultural entomologists, the book is readable and appropriate for others who just have a liking for these interesting and attractive insects.

A beautifully illustrated guide to all the ladybirds of Britain and Ireland. "A ground-breaking identification guide ... the perfect marriage of artistic excellence, deep knowledge and, dare I say it, of scientists' genuine affection." BRETT WESTWOOD This brand new illustrated field guide covers all 47 species of ladybird occurring in the British Isles in a handy and easy-to-use format. Twenty-seven species are colorful and conspicuous and easily recognized as ladybirds; the remaining species are more challenging, but the clear illustrations and up-to-date text in this guide will help to break down the identification barriers. A useful introduction provides an overview of ladybird ecology, tips on studying and recording, and suggested sites for finding ladybirds. The main part of the book comprises detailed species texts, covering field characters, food, habitats, suggested survey methods, ranges, conservation statuses and distribution trends. An illustrated at-a-glance identification guide and helpful pointers for differentiating similar-looking species are also included. With 102 color photographs and 47 distribution maps, combined with Richard Lewington's peerless artwork, this is the definitive guide to one of our most cherished and charismatic insect groups.

Brightly coloured and pleasingly patterned, ladybirds are among some of our most beloved and familiar invertebrates. Their role in helping to protect our crops by devouring huge numbers of pests has firmly established these tiny, flying beetles as the gardeners' friend. Spotlight Ladybirds focuses on the 26 species that are resident in the UK, from the widespread but unusual Orange Ladybird to the rare -- and aptly named -- Scarce 7-spot Ladybird. Ladybird expert, Richard Comont considers the conservation challenges facing these iconic species, whose populations are now at risk thanks to the threat posed by one of their own, the invasive alien Harlequin Ladybird. And he covers all aspects of ladybirds' biology, from tiny larvae emerging from their oval eggs to large aggregations that converge at specific sites around the world. Richard also examines the natural history and cultural significance of this fascinating group of beetles, from Ladybird Books to Thor.

This book addresses the fundamental issues of predator-prey interactions, with an emphasis on predation among arthropods, which have been better studied, and for which the database is more extensive than for the large and rare vertebrate predators. The book should appeal to ecologists interested in the broad issue of predation effects on communities.

Harmonia axyridis has been described as the “most invasive ladybird on Earth”. It has a long history of use as a classical biological control agent in the USA and more recently in Europe. This beetle has been effective at controlling pest insects in a variety of crop systems but it poses unacceptable risks by impacting on non-target species as both an intraguild predator and competitor. Written by renowned scientists, this book is a synthesis of recent research on H. axyridis and provides informative insights into current perspectives and future directions. Biological control is an essential component of sustainable agriculture but the distinction between a successful biological control agent and an invasive species can be narrow. We hope that lessons can be learnt from H. axyridis.

Coccinellids have been very actively studied in the course of the twenty three years since "Biology of Coccinellidae" was published. The great amount of new, and often very important findings have made the previous book outdated and a new synthesis is needed. No other monograph of similar focus and extent has appeared. Iablokoff Khnzorian's "Les Coccinelles" (1982), limited to the tribus Coccinellini, and Gor don's "The Coccinellidae of America North of Mexico" (1985) both concentrate on taxonomy. Majerus' beautiful "Ladybirds" (1994) deal specifically with British coc cinellids and address chiefly amateur naturalists. The focus and the title of the recent book are slightly different from the 1973 vol ume. If a satisfactory comprehensive review of important new findings is attempted, the book would grow too much, due also to References and Indexes. To keep the vol ume at a tolerable extent, the section on larval identification of Palaearctic species has been omitted; not much could be added to the previous version of that part, any way. However, we have kept Kovar's chapter on morphology and anatomy, because of its relation to feeding and other ecological aspects. The chapter on phylogeny was updated also by him. Our Polish friend, Piotr Ceryngier, who has recently specialised in parasites, updated perfectly the parts on parasites and pathogens in Chapter 8. We would be glad if their contribution is quoted by their names. It seems to us that the remarks, contained in the reprinted preface to the previous volume, remain pertinent today.

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.

Plant Ecology & Conservation is an introduction to the world of plant ecology. It includes the main areas of current research including ideas about plant populations, nutrition and plant community ecology and has a particular emphasis on the interactions of plants with animals, fungi and microorganisms whose important is being increasingly demonstrated. With the world’s environmental problems having such a high profile, the book focusses on the human impact on the world’s plant species. Conservation of the terrestrial world starts with plants as they form the basis of all ecosystems on land. We can only understand how best to conserve the world’s biodiversity with an understanding of the central role of plant ecology. This theme runs throughout with numerous examples of the disruption of ecosystems by human activity emphasising the connection between plant ecology and conservation. Key Features: Boxes present case studies, important statistics and interesting asides Full-colour photos depict key species and habitats and superb line drawings illustrate many concepts Important data are presented in Tables and Figures throughout Each chapter has Key Concepts and review questions to test a reader’s grasp of the content Key References and Further Reading are given for each chapter to point the reader towards the most important and influential literature Jargon is kept to a minimum and a full Glossary of all technical terms is presented The book is aimed primarily at undergraduate and graduate students in any aspect of ecology or plant science. It should also appeal to anyone interested in how plants function and are concerned about what is needed for the conservation of the world’s ecosystems.

This overview of the roles of alien species in insect conservation brings together information, evidence and examples from many parts of the world to illustrate their impacts (often severe, but in many cases poorly understood and unpredictable) as one of the primary drivers of species declines, ecological changes and biotic homogenisation. Both accidental and deliberate movements of species are involved, with alien invasive plants and insects the major groups of concern for their influences on native insects and their environments. Risk assessments, stimulated largely through fears of non-target impacts of classical biological control agents introduced for pest management, have provided valuable lessons for wider conservation biology. They emphasise the needs for effective biosecurity, risk avoidance and minimisation, and evaluation and management of alien invasive species as both major components of many insect species conservation programmes and harbingers of change in invaded communities. The spread of highly adaptable ecological generalist invasive species, which are commonly difficult to detect or monitor, can be linked to declines and losses of numerous localised ecologically specialised insects and disruptions to intricate ecological interactions and functions, and create novel interactions with far-reaching consequences for the receiving environments. Understanding invasion processes and predicting impacts of alien species on susceptible native insects is an important theme in practical insect conservation.
