Animals Mate

"Where do babies come from?" It's a question every child asks eventually, and Animals Mate is the simple, straightforward, and developmentally appropriate guide every parent needs to normalize sexual reproduction via adorable animal partners. With a modern design and beautiful illustrations, Animals Mate introduces facts about mating, including tactful discussion of the mechanics of the process, anatomy, and sperm and eggs. Bypass the awkwardness that often accompanies "the talk" about how babies are made and help your child understand sex and reproduction as the natural and wonderful process that results in the world's greatest treasure: babies!

Birds do it, bees do it, penguins do it, and orangutans do it. By having sex and giving birth to offspring, animals ensure that their species will survive into the next generation. And in this quest for survival, animals go to great lengths. Some animal mating techniques may strike you as strange or gross, but to the animals themselves, these practices are essential. Animals with the best strategies for choosing mates and making babies ensure that their species live on. Without animal sex, there would be no animal life.

Sperm Competition and the Evolution of Animal Mating Systems describes the role of sperm competition in selection on a range of attributes from gamete morphology to species mating systems. This book is organized into 19 chapters and begins with the conceptualization of sperm competition as a subset of sexual selection and its implications for the insects. The following chapter describes the relationship between multiple mating and female fitness, with an emphasis on determining the conditions under which selection on females is likely to counteract selection on males for avoiding sperm competition. Other chapters consider the female perspective on sperm competition; the evolutionary causation at the level of the individual male gamete; and the correlation of high paternal investment and sperm precedence in the insects. The remaining chapters are arranged phylogenetically and explore the sperm competition in diverse animal taxa, such as the Drosophila, Lepidoptera, spiders, amphibians, and reptiles. These chapters also cover the evolution of direct versus indirect sperm transfer among the arachnids or the problem for kinship theory presented by multiple mating and sperm competition in the Hymenoptera. This book further discusses the remarkable potential for sperm competition among certain temperate bat species whose females store sperm through winter hibernation and the mixed strategies and male-caused female genital trauma as possible sperm competition adaptations in poeciliid fishes. The concluding chapter examines the predictions concerning testes size and mating systems in the primates and the possible role of sperm competition in human selection. This book is of great value to reproductive biologists and researchers.

The Barnacle Goose, a distinctive, handsome black-and-white bird, gets its name from a mediaeval myth that the birds hatched from barnacles – how else to explain their sudden appearance each autumn in northern Britain? We now know, of course, that the birds migrate from Arctic Russia, Norway and Svalbard to winter throughout northern Europe. This book represents a culmination of more than 25 years of Barnacle Goose research. It represents the story of one of Europe's most celebrated long-term behavioral studies, detailing the lives of these social and sociable birds. Chapters include sections on pair formation and bonding, family and population dynamics, brood parasitism, food and feeding, size and shape in different populations, life cycle, survivorship, dispersal, migration, and conservation, with particular regard to climate change. It is a rigorous and thorough examination of the lives of these birds, in fine Poyser tradition.

No philosophical idea, no matter how small, can live alone. Ideas always gain their force, power, and life from their surroundings - their ecosystem. The ecosystem of ideas defended in this book comes from the ancient Greek philosopher Aristotle and his medieval interpreter, Thomas Aquinas. The ongoing relevance of their philosophical thought to twenty-first century issues is opened up in fascinating ways in this book. Life, the Universe, and Everything is the product of thirty years of teaching introductory courses in philosophy. Assuming no prior background, it only requires of readers an enquiring mind and a willingness to think carefully. An ideal guide to the big questions we face.

Wild Kingdom meets Sex and the City in this scientific perspective on dating and relationships. A specialist in animal behavior compares the courtship rituals and mating behaviors of animals to their human equivalents, revealing the many and often surprising ways we are both similar to and different from other species. What makes an individual attractive to the opposite sex? Does size matter? Why do we tend to "keep score" in our relationships? From perfume and cosmetics to online dating and therapy, our ultimate goal is to successfully connect with someone. So why is romance such an effort for humans, while animals have little trouble getting it right? Wild Connection is full of fascinating and suggestive observations about animal behavior. For example, in most species smell is an important component of determining compatibility. So are we humans doing the right thing by masking our natural scents with soaps and colognes? Royal albatrosses have a lengthy courtship period lasting several years. These birds instinctively know that casual hook-ups are not the way to find a reliable mate. And older female chimpanzees often mate with younger males. Is this the evolutionary basis of the human "cougar" phenomenon? Fun to read as well as educational, this unique take on the perennial human quest to find the ideal mate shows that we have much to learn from our cousins in the wild.

One of the main problems and aims of nature conservation in Europe is to protect semi-open landscapes. The development during the past decades is characterized by an ongoing intensivation of land use on the one hand, and an increasing number of former meadows and pastures lying fallow caused by changing economic conditions on the other hand. In several countries the estabishment of larger "pasture landscapes" with a mixed character of open grassland combined with shrubs and forests has been recognized as one solution to this problem. The book gives an overview of the European projects concerning to this topic - nature conservation policy and strategies, scientific results and practical experiences creating large scale grazing systems.
