Book Description
This book discusses the evolution of the mechanisms by which prey avoid attack by their potential predators and questions how such defences are maintained through natural selection. Topics covered include camouflage, warning signals and mimicry.

Book Description
The present book analyses critically the tripartite mimicry model (consisting of the mimic, model and receiver species) and develops semiotic tools for comparative analysis. It is proposed that mimicry has a double structure where sign relations in communication are in constant interplay with ecological relations between species. Multi-constructivism and toolbox-like conceptual methods are advocated for, as these allow taking into account both the participants’ Umwelten as well as cultural meanings related to specific mimicry cases. From biosemiotic viewpoint, mimicry is a sign relation, where deceptively similar messages are perceived, interpreted and acted upon. Focusing on living subjects and their communication opens up new ways to understand mimicry. Such view helps to explain the diversity of mimicry as well as mimicry studies and treat these in a single framework. On a meta-level, a semiotic view allows critical reflection on the use of mimicry concept in modern biology. The author further discusses interpretations of mimicry in contemporary semiotics, analyses mimicry as communicative interaction, relates mimicry to iconic signs and focuses on abstract resemblances in mimicry. Theoretical discussions are illustrated with detailed excursions into practical mimicry cases in nature (brood parasitism, eyespots, myrmecomorphy, etc.). The book concludes with a conviction that mimicry should be treated in a broader semiotic-ecological context as it presumes the existence of ecological codes and other sign conventions in the ecosystem.

Book Description
Revealing the web of mutual influences between nineteenth-century scientific and cultural discourses of appearance, Mimicry and Display in Victorian Literary Culture argues that Victorian science and culture biologized appearance, reimagining imitation, concealment and self-presentation as evolutionary adaptations. Exploring how studies of animal crypsis and visibility drew on artistic theory and techniques to reconceptualise nature as a realm of signs and interpretation, Abberley shows that in turn, this science complicated religious views of nature as a text of divine meanings, inspiring literary authors to rethink human appearances and perceptions through a Darwinian lens. Providing fresh insights into writers from Alfred Russel Wallace and Thomas Hardy to Oscar Wilde and Charlotte Perkins Gilman, Abberley reveals how the biology of appearance generated new understandings of deception, identity and creativity; reacted upon narrative forms such as crime fiction and the pastoral; and infused the rhetoric of cultural criticism and political activism.

Book Description
Insects provide excellent model systems for understanding evolutionary ecology. They are abundant, small, and relatively easy to rear, and these traits facilitate both field and laboratory experiments. This book has been developed from the Royal Entomological Society's 22nd international symposium, held in Reading in 2003. Topics include speciation and adaptation; life history, phenotype plasticity and genetics; sexual selection and reproductive biology; insect-plant interactions; insect-natural enemy interactions; and social insects.

Book Description
In recent years there has been an unprecedented expansion of knowledge about anthocyanins pigments. Indeed, the molecular genetic control of anthocyanins biosynthesis is now one of the best understood of all secondary metabolic pathways. There have also been substantial improvements in analytical technology that have led to the discovery of novel anthocyanin compounds. Armed with this knowledge and the tools for genetic engineering, plant breeders are now introducing vibrant new colors into horticultural crops. The food industry has also benefited from the resurgence of interest in anthocyanins. A greater understanding of the chemistry of these pigments has led to improved methods for stabilizing the color of anthocyanins extracts, so that they are more useful as food colorings. Methods for the bulk production of anthocyanins from cell cultures have been optimized for this purpose. Possible benefits to human health from the ingestion of anthocyanin-rich foods have also been a major feature of the recent scientific literature. Anthocyanins are remarkably potent antioxidants, and their ingestion has been postulated to stave off the effects of oxidative stress. These pigments, especially in conjunction with other flavonoids, have been associated with reductions in the incidence and severity of many other non-infectious diseases, including diabetes, cardiovascular disease and certain cancers. An industry is developing around anthocyanins as nutritional supplements. Finally, there has been significant progress in our understanding of the benefits of anthocyanins to plants themselves. Originally considered an extravagance without a purpose, anthocyanins are now implicated in multifarious vital functions. These include the attraction of pollinators and frugivores, aposematic defense from herbivores, and protection from environmental stressors such as strong light, UVB, drought, and free radical attacks. Anthocyanins are evidently highly versatile, and enormously useful to plants. This book covers all aspects of the biosynthesis and function of anthocyanins (and related compounds such as proanthocyanidins) in plants, and their applications in agriculture, food products, and human health. Featured areas include their relevance to: * Plant stress * Flower and fruit color * Human health * Wine quality and health attributes * Food colorants and ingredients * Cell culture production systems * The pastoral sector

Book Description
Nature has perfected the art of deception. Thousands of creatures all over the world - including butterflies, moths, fish, birds, insects and snakes - have honed and practised camouflage over hundreds of millions of years. Imitating other animals or their surroundings, nature's fakers use mimicry to protect themselves, to attract and repel, to bluff and warn, to forage and to hide. The advantages of mimicry are obvious - but how does 'blind' nature do it? And how has humanity learnt to profit from nature's ploys? "Dazzled and Deceived" tells the unique and fascinating story of mimicry and camouflage in science, art, warfare and the natural world. Discovered in the 1850s by the young English naturalists Henry Walter Bates and Alfred Russel Wallace in the Amazonian rainforest, the phenomenon of mimicry was seized upon as the first independent validation of Darwin's theory of natural selection. But mimicry and camouflage also created a huge impact outside the laboratory walls. Peter Forbes' cultural history links mimicry and camouflage to art, literature, military tactics and medical cures across the twentieth century, and charts its intricate involvement with the dispute between evolution and creationism.
