Her fascinating and wide-ranging work provides clear explanations of the science surrounding keystone predators and considers how this notion can help provide practical solutions for restoring ecosystem health and functioning.Eisenberg examines both general concepts and specific issues, sharing accounts from her own fieldwork to illustrate and bring to life the ideas she presents. She considers how resource managers can use knowledge about trophic cascades to guide recovery efforts, including how this science can be applied to move forward the bold vision of rewilding the North American continent. In the end, the author provides her own recommendations for local and landscape-scale applications of what has been learned about interactive food webs.At their most fundamental level, trophic cascades are powerful stories about ecosystem processes of predators and their prey, of what it takes to survive in a landscape, of the flow of nutrients. The Wolf’s Tooth is the first book to focus on the vital connection between trophic cascades and restoring biodiversity and habitats, and to do so in a way that is accessible to a diverse readership.

    To Lee Goff and his fellow forensic entomologists, each body recovered at a crime scene is an ecosystem, a unique microenvironment colonized in succession by a diverse array of flies, beetles, mites, spiders, and other arthropods: some using the body to provision their young, some feeding directly on the tissues and by-products of decay, and still others preying on the scavengers.Using actual cases on which he has consulted, Goff shows how knowledge of these insects and their habits allows forensic entomologists to furnish investigators with crucial evidence about crimes. Even when a body has been reduced to a skeleton, insect evidence can often provide the only available estimate of the postmortem interval, or time elapsed since death, as well as clues to whether the body has been moved from the original crime scene, and whether drugs have contributed to the death.An experienced forensic investigator who regularly advises law enforcement agencies in the United States and abroad, Goff is uniquely qualified to tell the fascinating if unsettling story of the development and practice of forensic entomology.

    A young man is murdered for his prized pet fish. An Asian tycoon buys a single specimen for $150,000. Meanwhile, a pet detective chases smugglers through the streets of New York. Delving into an outlandish world of obsession, paranoia, and criminality, The Dragon Behind the Glass tells the story of a fish like none other. Treasured as a status symbol believed to bring good luck, the Asian arowana, or “dragon fish,” is a dramatic example of a modern paradox: the mass-produced endangered species. While hundreds of thousands are bred in captivity, the wild fish has become a near-mythical creature. From the South Bronx to Borneo and beyond, journalist Emily Voigt follows the trail of the arowana to learn its fate in nature. With a captivating blend of personal reporting, history, and science, Voigt traces our fascination with aquarium fish back to the era of exploration when intrepid naturalists stood on the cutting edge of modern science, discovering new species around the globe. In an age when freshwater fish now comprise one of the most rapidly vanishing groups of animals, she unearths a surprising truth behind the arowana’s rise to fame—one that calls into question how we protect the world’s rarest species. An elegant examination of the human conquest of nature, The Dragon Behind the Glass revels in the sheer wonder of life’s diversity and lays bare our deepest desire—to hold on to what is wild.

    Now she builds on those insights to show us how to give our animals the best and happiest life—on their terms, not ours.It’s usually easy to pinpoint the cause of physical pain in animals, but to know what is causing them emotional distress is much harder. rawing on the latest research and her own work,Grandin identifies the core emotional needs of animals. Then she explains how to fulfill them for dogs and cats, horses, farm animals, and zoo animals.Whether it’s how to make the healthiest environment for the dog you must leave alone most of the day, how to keep pigs from being bored, or how to know if the lion pacing in the zoo is miserable or just exercising, Grandin teaches us to challenge our assumptions about animal contentment and honor our bond with our fellow creatures.Animals Make Us Human is the culmination of almost thirty years of research, experimentation, and experience.This is essential reading for anyone who’s ever owned, cared for, or simply cared about an animal.
