This monograph is the first of its kind devoted entirely to the dragonfly nymphs of North America north of Mexico, the focus being accurate identification of the 330 species of Anisoptera that occur in the region. Nymphal external morphology is described and illustrated in detail, and all terms needed to navigate the dichotomous keys are defined. Species are tabulated with references that provide the most detailed, accurate descriptions for each; species that are inadequately described are so indicated. The key separating the seven families in the region contains several new characters. The families are then covered separately: Aeshnidae (13 genera), Gomphidae (17 genera), Petaluridae (2 genera), Cordulegastridae (2 genera), Macromiidae (2 genera), Corduliidae (7 genera), and Libellulidae (29 genera). Each family is further characterized, followed by a generic key. A drawing of the habitus and diagnostic details for each genus are provided, along with additional diagnostic remarks and notes on habitat and life cycle; for each genus, a map shows its geographic distribution in North America. Full-grown nymphs of all known species of each genus are keyed and diagnosed; characters that apply to earlier instars are noted. Morphological variation in character states was analyzed in order to assess the reliability of previously utilized characters and to discover new characters. Most of the characters used to distinguish all levels of taxa are illustrated; a total of 702 figures, comprising 1,800 original drawings, along with selected photographs where necessary for clarity, accompany the keys. Measurements of total length, head width, and other variables for each species are provided in tables. Difficulties with past keys and descriptions, including errors, omissions and other shortcomings, are addressed. The importance of nymph characters in helping solve generic and specific distinctions and their role in phylogenetic studies is emphasized. Methods for collecting, rearing, and preserving dragonfly nymphs and exuviae are presented. The final chapter discusses research opportunities on North American Anisoptera nymphs, including taxonomic needs, studies on structure and function, life history and microhabitat, water quality indices and conservation efforts. The habitus drawings of all genera are arranged according to family in five plates (Appendix I); although the book is intended as a lab manual, these plates conveniently allow for comparison based on nymph shape making field identification to genus possible in many cases. Appendix II contains a brief history of dragonfly nymph studies in North America. A glossary and an index to scientific names are included.

A self-obsessed Calcutta detective who goes by his last name `Kar’, an enigmatic internet cafe hostess in Seoul, and a hotshot geneticist labouring away on a top-secret corporate project. These are just a few pieces in the puzzle that need to be put together to explain a world sucked into the whirlpool of the `butterfly effect’. In the decaying capital city of a near-future Darkland, which covers large swathes of Asia, Captain Old – an off-duty policeman – receives news that might help to unravel the roots of a scourge that has ravaged the continent. As stories coalesce into stories – welding past, present and future together – will a macabre death in a small English town or the disappearance of Indian tourists in Korea, help to blow away the dusts of time? From utopian communities of Asia to the prison camps of Pyongyang and from the gene labs of Europe to the violent streets of Darkland – riven by civil war, infested by genetically engineered fighters – this time-travelling novel crosses continents, weaving mystery, adventure and romance, gradually fixing its gaze on the sway of the unpredictable over our lives.

Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Although the majority of consumed insects are gathered in forest habitats, mass-rearing systems are being developed in many countries. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. It shows the many traditional and potential new uses of insects for direct human consumption and the opportunities for and constraints to farming them for food and feed. It examines the body of research on issues such as insect nutrition and food safety, the use of insects as animal feed, and the processing and preservation of insects and their products. It highlights the need to develop a regulatory framework to govern the use of insects for food security. And it presents case studies and examples from around the world. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. To fully realise this potential, much work needs to be done by a wide range of stakeholders. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.

The first broad overview of conservation needs of Australia’s largely endemic freshwater insects, drawing on examples and information from many parts of the world to illustrate and develop needs and practical prospects for conservation in inland water environments. The wide variety of those environments in Australia and their diverse insect inhabitants – many of them highly localised and ecologically specialised and vulnerable - and threats to them is illustrated. Case histories demonstrate the different aspects of practical conservation management that may be possible in different contexts, and numerous references facilitate understanding by non-specialist readers and non-entomologist conservation managers and practitioners.

For fans of Erin Entrada Kelly and Ali Benjamin comes a poignant yet hopeful novel about a girl navigating grief, trauma, and friendship, from Ashley Herring Blake, the award-winning author of Ivy Aberdeen's Letter to the World. Hazel Bly used to live in the perfect house with the perfect family in sunny California. But when a kayaking trip goes horribly wrong, Mum is suddenly gone forever and Hazel is left with crippling anxiety and a jagged scar on her face. After Mum's death, Hazel, her other mother, Mama, and her little sister, Peach, needed a fresh start. So for the last two years, the Bly girls have lived all over the country, never settling anywhere for more than a few months. When the family arrives in Rose Harbor, Maine, there's a wildness to the small town that feels like magic. But when Mama runs into an old childhood friend—Claire—suddenly Hazel's tight-knit world is infiltrated. To make it worse, she has a daughter Hazel's age, Lemon, who can't stop rambling on and on about the Rose Maid, a local 150-year-old mermaid myth. Soon, Hazel finds herself just as obsessed with the Rose Maid as Lemon is—because what if magic were real? What if grief really could change you so much, you weren't even yourself anymore? And what if instead you emerged from the darkness stronger than before?

Genetic algorithms are playing an increasingly important role in studies of complex adaptive systems, ranging from adaptive agents in economic theory to the use of machine learning techniques in the design of complex devices such as aircraft turbines and integrated circuits. Adaptation in Natural and Artificial Systems is the book that initiated this field of study, presenting the theoretical foundations and exploring applications. In its most familiar form, adaptation is a biological process, whereby organisms evolve by rearranging genetic material to survive in environments confronting them. In this now classic work, Holland presents a mathematical model that allows for the nonlinearity of such complex interactions. He demonstrates the model's universality by applying it to economics, physiological psychology, game theory, and artificial intelligence and then outlines the way in which this approach modifies the traditional views of mathematical genetics. Initially applying his concepts to simply defined artificial systems with limited numbers of parameters, Holland goes on to explore their use in the study of a wide range of complex, naturally occuring processes, concentrating on systems having multiple factors that interact in nonlinear ways. Along the way he accounts for major effects of coadaptation and coevolution: the emergence of building blocks, or schemata, that are recombined and passed on to succeeding generations to provide, innovations and improvements.

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.
