Book excerpt: Emlen takes us outside the lab and deep into the forests and jungles where he's been studying animal weapons in nature for years, to explain the processes behind the most intriguing and curious examples of extreme animal weapons. As singular and strange as some of the weapons we encounter on these pages are, we learn that similar factors set their evolution in motion. Emlen uses these patterns to draw parallels to the way we humans develop and employ our own weapons, and have since battle began.

Download or read book Deer Antlers written by Richard J. Goss and published by Academic Press. This book was released on 2012-12-02 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a book about one of nature's most remarkable accomplishments. When deer grow antlers they are actually regenerating anatomically complex appendages - something that no other mammal can do. The rate at which antler elongate makes them the fastest growing structures in the animal kingdom. Profoundly affected by male hormones, these secondary sex characters grow into massive tumors if the deer possessing them is castrated. These and other unique characteristics have made antlers the focus of extensive scientific research that addresses some provocative questions: From what tissues do antlers develop? By what morphogenetic mechanisms are they regenerated every year? What social functions prompted their initial evolution? How are they influenced by hormones, and by the seasonal daylength fluctuations that regulate their annual replacement cycles? These and many other questions are considered in this comprehensive account of antlerology.Students of development, evolution, and behavior will find much to appreciate in this volume, as will ecologists, wildlife biologists, and zookeepers. It is a rich source of information for endocrinologists and physiologists interested in the relationship of antlers to the reproductive cycle. The orthopedists will find the study of antlers a valuable model of skeletal growth and bone disease, and the purported medicinal properties of velvet antlers will be a subject of interest to the pharmacologist.Deer Antlers: Regeneration, Function, and Evolution is as scientifically accurate as it is readable. It does not answer all questions about these unique appendages, but it is certain to arouse curiosity about the many unsolved problems of how antlers grow, die, and are shed in the course of a single year.

Download or read book Poached written by Rachel Love Nuwer and published by Hachette UK. This book was released on 2018-09-25 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: An intrepid investigation of the criminal world of wildlife trafficking--the poachers, the traders, and the customers--and of those fighting against it Journalist Rachel Nuwer plunges the reader into the underground of global wildlife trafficking, a topic she has been investigating for nearly a decade. Our insatiable demand for animals -- for jewelry, pets, medicine, meat, trophies, and fur -- is driving a worldwide poaching epidemic, threatening the continued existence of countless species. Illegal wildlife trade now ranks among the largest contraband industries in the world, yet compared to drug, arms, or human trafficking, the wildlife crisis has received scant attention and support, leaving it up to passionate individuals fighting on the ground to try to ensure that elephants, tigers, rhinos, and more are still around for future generations. As Reefer Madness (Schlosser) took us into the drug market, or Susan Orlean descended into the swampy obsessions of TheOrchid Thief, Nuwer--an award-winning science journalist with a background in ecology--takes readers on a narrative journey to the front lines of the trade: to killing fields in Africa, traditional medicine black markets in China, and wild meat restaurants in Vietnam. Through exhaustive first-hand reporting that took her to ten countries, Nuwer explores the forces currently driving demand for animals and their parts; the toll that demand is extracting on species across the planet; and the conservationists, rangers, and activists who believe it is not too late to stop the impending extinctions. More than a depressing list of statistics, Poached is the story of the people who believe this is a battle that can be won, that our animals are not beyond salvation.
