Book Description
Melanism: Evolution in Action describes investigations into a ubiquitous biological phenomenon, the existence of dark, or melanic, forms of many species of mammals, insects, and some plants. Melanism is a particularly exciting phenomenon in terms of our understanding of evolution. Unlike manyother polymorphisms, the rise of a melanic population within a species is a visible alteration. Not only this, but melanism may sometimes occur dramatically quickly compared to other evolutionary change. Examples of melanism include one of the most famous illustrations of Darwinian naturalselection, the peppered moth. This book, the first written on melanism since 1973, gives a lucid and up-to-date appraisal of the subject. The book is divided into ten chapters. The first four chapters place melanism into its historical and scientific context, with illustrations of its occurrence,and physical and genetic properties. Chapters 5-9 look in more detail at melanism in moths and ladybirds, explaining the diversity of evolutionary reasons for melanism, and the complexities underlying this apparently simple phenomenon. The final chapter shows how the study of melanism has contibutedto our understanding of biological evolution as a whole. Written in an engaging and readable style, by an author whose enthusiasm and depth of knowledge is apparent throughout, this book will be welcomed by all students and researchers in the fields of evolution, ecology, entomology, and genetics.It will also be of relevance to professional and amateur entomologists and lepidopterists alike.

Book Description
In this revelatory work, Judith Hooper uncovers the intellectual rivalries, petty jealousies, and flawed science behind one of the most famous experiments in evolutionary biology. Bernard Kettlewell's 1953 experiment on the peppered moths of England made him a media star on the order of Jonas Salk -- but also an unlikely tragic hero. As Hooper recounts in this rollicking scientific detective story, the truth can be subverted when the stakes are very high. Book jacket.

Book Description
*Carrion crows in the Japanese city of Sendai have learned to use passing traffic to crack nuts. *Lizards in Puerto Rico are evolving feet that better grip surfaces like concrete. *Europe’s urban blackbirds sing at a higher pitch than their rural cousins, to be heardover the din of traffic. How is this happening? Menno Schilthuizen is one of a growing number of “urban ecologists” studying how our manmade environments are accelerating and changing the evolution of the animals and plants around us. In Darwin Comes to Town, he takes us around the world for an up-close look at just how stunningly flexible and swift-moving natural selection can be. With human populations growing, we’re having an increasing impact on global ecosystems, and nowhere do these impacts overlap as much as they do in cities. The urban environment is about as extreme as it gets, and the wild animals and plants that live side-by-side with us need to adapt to a whole suite of challenging conditions: they must manage in the city’s hotter climate (the “urban heat island”); they need to be able to live either in the semidesert of the tall, rocky, and cavernous structures we call buildings or in the pocket-like oases of city parks (which pose their own dangers, including smog and free-rangingdogs and cats); traffic causes continuous noise, a mist of fine dust particles, and barriers to movement for any animal that cannot fly or burrow; food sources are mainly human-derived. And yet, as Schilthuizen shows, the wildlife sharing these spaces with us is not just surviving, but evolving ways of thriving. Darwin Comes toTown draws on eye-popping examples of adaptation to share a stunning vision of urban evolution in which humans and wildlife co-exist in a unique harmony. It reveals that evolution can happen far more rapidly than Darwin dreamed, while providing a glimmer of hope that our race toward over population might not take the rest of nature down with us.

Book Description
Although biologists recognize evolutionary ecology by name, many only have a limited understanding of its conceptual roots and historical development. Conceptual Breakthroughs in Evolutionary Ecology fills that knowledge gap in a thought-provoking and readable format. Written by a world-renowned evolutionary ecologist, this book embodies a unique blend of expertise in combining theory and experiment, population genetics and ecology. Following an easily-accessible structure, this book encapsulates and chronologizes the history behind evolutionary ecology. It also focuses on the integration of age-structure and density-dependent selection into an understanding of life-history evolution. - Covers over 60 seminal breakthroughs and paradigm shifts in the field of evolutionary biology and ecology - Modular format permits ready access to each described subject - Historical overview of a field whose concepts are central to all of biology and relevant to a broad audience of biologists, science historians, and philosophers of science
