Mimicry is a classic example of adaptation through natural selection. The traditional focus of mimicry research has been on defence in animals, but there is now also a highly-developed and rapidly-growing body of research on floral mimicry in plants. This has coincided with a revolution in genomic tools, making it possible to explore which genetic and developmental processes underlie the sometimes astonishing changes that give rise to floral mimicry. Beingliterally rooted to one spot, plants have to cajole animals into acting as couriers for their pollen. Floral mimicry encompasses a set of evolutionary strategies whereby plants imitate the food sources,oviposition sites, or mating partners of animals in order to exploit them as pollinators. This first definitive book on floral mimicry discusses the functions of visual, olfactory, and tactile signals, integrating them into a broader theory of organismal mimicry that will help guide future research in the field. It addresses the fundamental question of whether the evolutionary and ecological principles that were developed for protective mimicry in animals can also beapplied to floral mimicry in plants. The book also deals with the functions of floral rewardlessness, a condition which often serves as a precursor to the evolution of mimicry in plant lineages. The authorspay particular attention to the increasing body of research on chemical cues: their molecular basis, their role in cognitive misclassification of flowers by pollinators, and their implications for plant speciation. Comprehensive in scope and conceptual in focus, Floral Mimicry is primarily aimed at senior undergraduates, graduate students, and researchers in plant science and evolutionary biology.

Bio-mimicry is fundamental idea ""How to mimic the Nature"" by various methodologies as well as new ideas or suggestions on the creation of novel materials and functions. This book comprises seven sections on various perspectives of bio-mimicry in our life; Section 1 gives an overview of modeling of biomimetic materials; Section 2 presents a processing and design of biomaterials; Section 3 presents various aspects of design and application of biomimetic polymers and composites are discussed; Section 4 presents a general characterization of biomaterials; Section 5 proposes new examples for biomimetic systems; Section 6 summarizes chapters, concerning cells behavior through mimicry; Section 7 presents various applications of biomimetic materials are presented. Aimed at physicists, chemists and biologists interested in biomineralization, biochemistry, kinetics, solution chemistry. This book is also relevant to engineers and doctors interested in research and construction of biomimetic systems.

Le 18 mai 2021, la sculpture Io sono («Je suis»), de l'Italien Salvatore Garau, s'est vendue 15000 euros. Particularité de l'œuvre? Elle est invisible et n'existe que parce que son créateur, revendiqué artiste du vide, l'a décrété. Son Bouddha en contemplation, fait du même «matériau», avait été exposé sur la place de la Scala, à Milan. Quel est le message? Selon l'artiste, ses sculptures invisibles sont une «parfaite métaphore de l'époque pleine de vide où nous vivons».À l'opposé du vide ainsi mis en lumière, l'invisible est un sujet cette fois très concret, et actif, qui traverse les sciences contemporaines, de la biologie à la physique quantique en passant par la sociologie et l'informatique, et les articles de ce Hors-Série en sont la preuve. «Le fléau n'est pas à la mesure de l'homme, on se dit donc que le fléau est irréel, c'est un mauvais rêve qui va passer.» Le fléau en question est la peste, dans le roman éponyme d'Albert Camus paru en 1947.

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.
