Fitness and adaptation are fundamental characteristics of plant and animal species, enabling them to survive in their environment and to adapt to the inevitable changes in this environment. This is true for both the genetic resources of natural ecosystems as well as those used in agricultural production. Extensive genetic variation exists between varieties/breeds in a species and amongst individuals within breeds. This variation has developed over very long periods of time. A major ongoing challenge is how to best utilize this variation to meet short-term demands whilst also conserving it for longer-term possible use. Many animal breeding programs have led to increased performance for production traits but this has often been accompanied by reduced fitness. In addition, the global use of genetic resources prompts the question whether introduced genotypes are adapted to local production systems. Understanding the genetic nature of fitness and adaptation will enable us to better manage genetic resources allowing us to make efficient and sustainable decisions for the improvement or breeding of these resources. This book had an ambitious goal in bringing together a sample of the world’s leading scientists in animal breeding and evolutionary genetics to exchange knowledge to advance our understanding of these vital issues.

*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.
Biological evolution is a fact—but the many conflicting theories of evolution remain controversial even today. When Adaptation and Natural Selection was first published in 1966, it struck a powerful blow against those who argued for the concept of group selection—the idea that evolution acts to select entire species rather than individuals. Williams’s famous work in favor of simple Darwinism over group selection has become a classic of science literature, valued for its thorough and convincing argument and its relevance to many fields outside of biology. Now with a new foreword by Richard Dawkins, Adaptation and Natural Selection is an essential text for understanding the nature of scientific debate.
A fish that walks on land, a frog that makes its own sunscreen, and an insect that can become invisible? These are just a few examples of how Earth's creatures have evolved some outrageous features and tricks to ensure survival.
Primate Adaptation and Evolutionis the only recent text published in this rapidly progressing field. It provides you with an extensive, current survey of the order Primates, both living and fossil. By combining information on primate anatomy, ecology, and behavior with the primate fossil record, this book enables students to study primates from all epochs as a single, viable group. It surveys major primate radiations throughout 65 million years, and provides equal treatment of both living and extinct species.ï Presents a summary of the primate fossilsï Reviews primate evolutionï Provides an introduction to the primate anatomyï Discusses the features that distinguish the living groups of primatesï Summarizes recent work on primate ecology
Early readers investigate various animal adaptations.
The Dusky Dolphin: Master Acrobat Off Different Shores covers various topics about the dusky dolphin, including its taxonomy, history and demography, ecology, and behavior. After introducing the dusky dolphin as a member of the genus Lagenorhynchus under the family Delphinidae, the book continues by describing its life history, its demographic patterns, and its role in the food web considering predation, parasitism, and competition. The book also includes chapters that discuss the interaction of the dusky dolphin with its habitats, such as the dusky dolphin's sound production, its foraging at night and in daylight, its survival strategies in response to predator threats, the mating habits of New Zealand duskies, calf rearing, sexual segregation, and genetic relationships. Other chapters address the interaction of dusky dolphins with humans. This book offers information about dusky dolphins off Southern Africa and discussions about the patterns of sympatry in Lagenorhynchus and Cephalorhynchus. Finally, comparisons between dusky dolphins and great apes as large-brained mammals are also reviewed in this book. - Only book fully devoted to the southern hemisphere "dusky" dolphin - Heavily illustrated with charts, figures, tables, and all color photos - Written by a cadre of experts intimately familiar with dolphin field work - Written in an accurate yet accessible style for the scientist and natural historian alike
Winner of the 2022 Rachel Carson Environment Book Award * Winner of the 2022 Science in Society Journalism Award (Books) * Finalist for the Los Angeles Times Book Prize “Thoughtful, insightful, and wise, Wild Souls is a landmark work.”--Ed Yong, author of An Immense World "Fascinating . . . hands-on philosophy, put to test in the real world . . . Marris believes that our idea of wildness--our obsession with purity--is misguided. No animal remains untouched by human hands . . . the science isn't the hard part. The real challenge is the ethics, the act of imagining our appropriate place in that world." --Outside Magazine From an acclaimed environmental writer, a groundbreaking and provocative new vision for our relationships with--and responsibilities toward--the planet's wild animals. Protecting wild animals and preserving the environment are two ideals so seemingly compatible as to be almost inseparable. But in fact, between animal welfare and conservation science there exists a space of underexamined and unresolved tension: wildness itself. When is it right to capture or feed wild animals for the good of their species? How do we balance the rights of introduced species with those already established within an ecosystem? Can hunting be ecological? Are any animals truly wild on a planet that humans have so thoroughly changed? No clear guidelines yet exist to help us resolve such questions. Transporting readers into the field with scientists tackling these profound challenges, Emma Marris tells the affecting and inspiring stories of animals around the globe--from Peruvian monkeys to Australian bilbies, rare Hawai'ian birds to majestic Oregon wolves. And she offers a companionable tour of the philosophical ideas that may steer our search for sustainability and justice in the non-human world. Revealing just how intertwined animal life and human life really are, Wild Souls will change the way we think about nature-and our place within it.
*A New York Times Editor's Choice pick *Shortlisted for the 2022 Pacific Northwest Book Awards A beloved natural historian explores how climate change is driving evolution In Hurricane Lizards and Plastic Squid, biologist Thor Hanson tells the remarkable story of how plants and animals are responding to climate change: adjusting, evolving, and sometimes dying out. Anole lizards have grown larger toe pads, to grip more tightly in frequent hurricanes. Warm waters cause the development of Humboldt squid to alter so dramatically that fishermen mistake them for different species. Brown pelicans move north, and long-spined sea urchins south, to find cooler homes. And when coral reefs sicken, they leave no territory worth fighting for, so aggressive butterfly fish transform instantly into pacifists. A story of hope, resilience, and risk, Hurricane Lizards and Plastic Squid is natural history for readers of Bernd Heinrich, Robin Wall Kimmerer, and David Haskell. It is also a reminder of how unpredictable climate change is as it interacts with the messy lattice of life.
