Böcker av Lee Alan Dugatkin

An engaging exploration of the wondrous social webs that permeate life in animal societies around the world. It's all about who you know. Whether vampire bats sharing blood meals for survival, field crickets remembering champion fighters, macaque monkeys forming grooming pacts after a deadly hurricane, or great tit birds learning the best way to steal milk--it pays to be well connected. In this tour of the animal kingdom, evolutionary biologist Lee Alan Dugatkin reveals a new field of study, uncovering social networks that existed long before the dawn of human social media. He accessibly describes the latest findings from animal behavior, evolution, computer science, psychology, anthropology, genetics, and neurobiology, and incorporates interviews and insights from researchers that he finds swimming with manta rays, avoiding pigeon poop, and stopping monkeys from stealing iPads. With Dugatkin as our guide, we investigate social networks in giraffes, elephants, kangaroos, Tasmanian devils, whales, bats, and more. From animal networks in Australia and Asia to Africa, Europe, and the Americas, The Well-Connected Animal is an eye-opening expose of wild friends, enemies, and everything in between.

"Hermit crabs might not be the first example that comes to mind when thinking about power in animal relationships, but they are representative of the costs, benefits, assessment, and struggles that animal behaviorist Lee Dugatkin explains in Power in the Wild. Besides learning that researchers can evict all crabs from their shells by tickling their abdomens with paintbrushes, readers discover that attacker crabs can assess both the quality of shells and the ability of competitors to hold onto them- and both attacker and attacked make decisions about how much energy to expend holding onto a good shell. If the attacker looks tough, a target might just give up and flee. That the models for these behaviors mirror game theory for nuclear deterrence is all the more interesting. Dugatkin makes clear that this is not a book about what non-human animal power dynamics can teach us about ourselves, but it is an overview of power in the animal world generally- from the costs of pursuing power, to the role of gender (including a description of a species of fish that changes gender depending on its rank), to new findings on observer animals that watch and assess greater community power relationships without participating in power struggles themselves"--

Since the last edition of this definitive textbook was published in 2013, much has happened in the field of animal behavior. In this fourth edition, Lee Alan Dugatkin draws on cutting-edge new work not only to update and expand on the studies presented, but also to reinforce the previous editions' focus on ultimate and proximate causation, as well as the book's unique emphasis on natural selection, learning, and cultural transmission. The result is a state-of-the-art textbook on animal behavior that explains underlying concepts in a way that is both scientifically rigorous and accessible to students. Each chapter in the book provides a sound theoretical and conceptual basis upon which the empirical studies rest. A completely new feature in this edition are the Cognitive Connection boxes in Chapters 2-17, designed to dig deep into the importance of the cognitive underpinnings to many types of behaviors. Each box focuses on a specific issue related to cognition and the particular topic covered in that chapter. As Principles of Animal Behavior makes clear, the tapestry of animal behavior is created from weaving all of these components into a beautiful whole. With Dugatkin's exquisitely illustrated, comprehensive, and up-to-date fourth edition, we are able to admire that beauty anew.

In the years after the Revolutionary War, the fledging republic of America was viewed by many Europeans as a degenerate backwater, populated by subspecies weak and feeble. This book recreates the origin and evolution of the debates about natural history in America.

In a world supposedly governed by ruthless survival of the fittest, why do we see acts of goodness in both animals and humans? This problem plagued Charles Darwin in the 1850s as he developed his theory of evolution through natural selection. Indeed, Darwin worried that the goodness he observed in nature could be the Achilles heel of his theory. Ever since then, scientists and other thinkers have engaged in a fierce debate about the origins of goodness that has dragged politics, philosophy, and religion into what remains a major question for evolutionary biology. The Altruism Equation traces the history of this debate from Darwin to the present through an extraordinary cast of characters-from the Russian prince Petr Kropotkin, who wanted to base society on altruism, to the brilliant biologist George Price, who fell into poverty and succumbed to suicide as he obsessed over the problem. In a final surprising turn, William Hamilton, the scientist who came up with the equation that reduced altruism to the cold language of natural selection, desperately hoped that his theory did not apply to humans. Hamilton's Rule, which states that relatives are worth helping in direct proportion to their blood relatedness, is as fundamental to evolutionary biology as Newton's laws of motion are to physics. But even today, decades after its formulation, Hamilton's Rule is still hotly debated among those who cannot accept that goodness can be explained by a simple mathematical formula. For the first time, Lee Alan Dugatkin brings to life the people, the issues, and the passions that have surrounded the altruism debate. Readers will be swept along by this fast-paced tale of history, biography, and scientific discovery.
