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
This timely book revisits cryptic female choice in arthropods, gathering detailed contributions from around the world to address key behavioral, ecological and evolutionary questions. The reader will find a critical summary of major breakthroughs in taxon-oriented chapters that offer many new perspectives and cases to explore and in many cases unpublished data. Many groups of arthropods such as spiders, harvestmen, flies, moths, crickets, earwigs, beetles, eusocial insects, shrimp and crabs are discussed. Sexual selection is currently the focus of numerous and controversial theoretical and experimental studies. Selection in mating and post-mating patterns can be shaped by several different mechanisms, including sperm competition, extreme sexual conflict and cryptic female choice. Discrimination among males during or after copulation is called cryptic female choice because it occurs after intromission, the event that was formerly used as the definitive criterion of male reproductive success and is therefore usually difficult to detect and confirm. Because it sequentially follows intra- and intersexual interactions that occur before copulation, cryptic female choice has the power to alter or negate precopulatory sexual selection. However, though female roles in biasing male paternity after copulation have been proposed for a number of species distributed in many animal groups, cryptic female choice continues to be often underestimated. Furthermore, in recent years the concept of sexual conflict has been frequently misused, linking sexual selection by female choice irrevocably and exclusively with sexually antagonistic co-evolution, without exploring other alternatives. The book offers an essential source of information on how two fields, selective cooperation and individual sex interests, work together in the context of cryptic female choice in nature, using arthropods as model organisms. It is bound to spark valuable discussions among scientists working in evolutionary biology across the world, motivating new generations to unveil the astonishing secrets of sexual biology throughout the animal kingdom.

Book Description
A major new look at the evolution of mating decisions in organisms from protozoans to humans The popular consensus on mate choice has long been that females select mates likely to pass good genes to offspring. In Mate Choice, Gil Rosenthal overturns much of this conventional wisdom. Providing the first synthesis of the topic in more than three decades, and drawing from a wide range of fields, including animal behavior, evolutionary biology, social psychology, neuroscience, and economics, Rosenthal argues that "good genes" play a relatively minor role in shaping mate choice decisions and demonstrates how mate choice is influenced by genetic factors, environmental effects, and social interactions. Looking at diverse organisms, from protozoans to humans, Rosenthal explores how factors beyond the hunt for good genes combine to produce an endless array of preferences among species and individuals. He explains how mating decisions originate from structural constraints on perception and from nonsexual functions, and how single organisms benefit or lose from their choices. Both the origin of species and their fusion through hybridization are strongly influenced by direct selection on preferences in sexual and nonsexual contexts. Rosenthal broadens the traditional scope of mate choice research to encompass not just animal behavior and behavioral ecology but also neurobiology, the social sciences, and other areas. Focusing on mate choice mechanisms, rather than the traits they target, Mate Choice offers a groundbreaking perspective on the proximate and ultimate forces determining the evolutionary fate of species and populations.

Book Description
Longlisted for the PEN/E.O. Wilson Literary Science Writing Award A leading neuroscientist offers a history of the evolution of the brain from unicellular organisms to the complexity of animals and human beings today Renowned neuroscientist Joseph LeDoux digs into the natural history of life on earth to provide a new perspective on the similarities between us and our ancestors in deep time. This page-turning survey of the whole of terrestrial evolution sheds new light on how nervous systems evolved in animals, how the brain developed, and what it means to be human. In The Deep History of Ourselves, LeDoux argues that the key to understanding human behavior lies in viewing evolution through the prism of the first living organisms. By tracking the chain of the evolutionary timeline he shows how even the earliest single-cell organisms had to solve the same problems we and our cells have to solve each day. Along the way, LeDoux explores our place in nature, how the evolution of nervous systems enhanced the ability of organisms to survive and thrive, and how the emergence of what we humans understand as consciousness made our greatest and most horrendous achievements as a species possible.

Book Description
Nearly twenty-five hundred years ago the Greek thinker Heraclitus supposedly uttered the cryptic words "Phusis kruptesthai philei." How the aphorism, usually translated as "Nature loves to hide," has haunted Western culture ever since is the subject of this engaging study by Pierre Hadot. Taking the allegorical figure of the veiled goddess Isis as a guide, and drawing on the work of both the ancients and later thinkers such as Goethe, Rilke, Wittgenstein, and Heidegger, Hadot traces successive interpretations of Heraclitus' words. Over time, Hadot finds, "Nature loves to hide" has meant that all that lives tends to die; that Nature wraps herself in myths; and (for Heidegger) that Being unveils as it veils itself. Meanwhile the pronouncement has been used to explain everything from the opacity of the natural world to our modern angst. From these kaleidoscopic exegeses and usages emerge two contradictory approaches to nature: the Promethean, or experimental-questing, approach, which embraces technology as a means of tearing the veil from Nature and revealing her secrets; and the Orphic, or contemplative-poetic, approach, according to which such a denuding of Nature is a grave trespass. In place of these two attitudes Hadot proposes one suggested by the Romantic vision of Rousseau, Goethe, and Schelling, who saw in the veiled Isis an allegorical expression of the sublime. "Nature is art and art is nature," Hadot writes, inviting us to embrace Isis and all she represents: art makes us intensely aware of how completely we ourselves are not merely surrounded by nature but also part of nature.

Book Description
INVESTIGATIVE REPORTERS & EDITORS Book Award, Finalist 2014 "A fascinating discussion of a multifaceted issue and a passionate call to action" --Kirkus From the acclaimed author of Four Fish and The Omega Principle, Paul Greenberg uncovers the tragic unraveling of the nation’s seafood supply—telling the surprising story of why Americans stopped eating from their own waters in American Catch In 2005, the United States imported five billion pounds of seafood, nearly double what we imported twenty years earlier. Bizarrely, during that same period, our seafood exports quadrupled. American Catch examines New York oysters, Gulf shrimp, and Alaskan salmon to reveal how it came to be that 91 percent of the seafood Americans eat is foreign. In the 1920s, the average New Yorker ate six hundred local oysters a year. Today, the only edible oysters lie outside city limits. Following the trail of environmental desecration, Greenberg comes to view the New York City oyster as a reminder of what is lost when local waters are not valued as a food source. Farther south, a different catastrophe threatens another seafood-rich environment. When Greenberg visits the Gulf of Mexico, he arrives expecting to learn of the Deepwater Horizon oil spill’s lingering effects on shrimpers, but instead finds that the more immediate threat to business comes from overseas. Asian-farmed shrimp—cheap, abundant, and a perfect vehicle for the frying and sauces Americans love—have flooded the American market. Finally, Greenberg visits Bristol Bay, Alaska, home to the biggest wild sockeye salmon run left in the world. A pristine, productive fishery, Bristol Bay is now at great risk: The proposed Pebble Mine project could under¬mine the very spawning grounds that make this great run possible. In his search to discover why this pre¬cious renewable resource isn’t better protected, Green¬berg encounters a shocking truth: the great majority of Alaskan salmon is sent out of the country, much of it to Asia. Sockeye salmon is one of the most nutritionally dense animal proteins on the planet, yet Americans are shipping it abroad. Despite the challenges, hope abounds. In New York, Greenberg connects an oyster restoration project with a vision for how the bivalves might save the city from rising tides. In the Gulf, shrimpers band together to offer local catch direct to consumers. And in Bristol Bay, fishermen, environmentalists, and local Alaskans gather to roadblock Pebble Mine. With American Catch, Paul Greenberg proposes a way to break the current destructive patterns of consumption and return American catch back to American eaters.
