Evidence pointing to a decline in the European Otter population (Lutra lutra) is causing concern among ecologists and conservationists. This important new book written from direct observation of otter populations in Scotland, is the first attempt at a scientific description of populations and behaviour of this species. This essential research offers a fascinating insight into the ecology of mammals living in a hostile environment and provides a much needed basis for active conservation management.
These booklets give the general reader facts and information about fur-bearing mammals from a more conservation-oriented perspective than information generally available from other sources. Each is based on the relevant SSC Action Plan, and is well-illustrated with color photographs and a center spread of sketches showing the animals in action.
Sea Otter Conservation by Shawn E. Larson,James L. Bodkin,Glenn R VanBlaricom Pdf
Sea otters are good indicators of ocean health. In addition, they are a keystone species, offering a stabilizing effect on ecosystem, controlling sea urchin populations that would otherwise inflict damage to kelp forest ecosystems. The kelp forest ecosystem is crucial for marine organisms and contains coastal erosion. With the concerns about the imperiled status of sea otter populations in California, Aleutian Archipelago and coastal areas of Russia and Japan, the last several years have shown growth of interest culturally and politically in the status and preservation of sea otter populations. Sea Otter Conservation brings together the vast knowledge of well-respected leaders in the field, offering insight into the more than 100 years of conservation and research that have resulted in recovery from near extinction. This publication assesses the issues influencing prospects for continued conservation and recovery of the sea otter populations and provides insight into how to handle future global changes. Covers scientific, cultural, economic and political components of sea otter conservation Provides guidance on how to manage threats to the sea otter populations in the face of future global changes Highlights the effects that interactions of coastal animals have with the marine ecosystem

Otters by Nicola Chester is an accessible and lively account of an intriguing and much-loved animal that, surprisingly, is still endangered and rarely seen despite a recent resurgence that has seen it expand from the remote countryside into our cities. Nicola's charming, informed text brings this elusive and exciting mammal into sharper focus revealing what an otter is, and how they live, feed, play and breed. Nicola reflects on how otters exist in our imaginations culturally and how that has changed over the years. She also examines the many challenges otters have faced, exposing what brought them to the brink of extinction, and explores the challenges we face in trying to find and watch otters in the wild. Each Spotlight title is carefully designed to introduce readers to the lives and behaviour of our favourite birds and mammals.

Sea otters once ruled the Pacific Ocean, but the fur trade of the eighteenth and nineteenth centuries brought this predator to near extinction. Today they’re slowly coming back from the brink, and scientists are learning more about their pivotal role as one of nature’s keystone species. This book looks at the history, biology, behavior and uncertain future of sea otters. Author and photojournalist Isabelle Groc takes us into the field: watching sea otter rafts off the British Columbia coast from a kayak, exploring what makes their fur coats so special, understanding how their voracious appetites are helping kelp forests thrive and, ultimately, learning how sea otters are leaving their mark (or paws) on every part of the ecosystem. They might be one of the most adorable creatures in the ocean, but kids will discover how their survival is key to a rich, complex and connected ecosystem.
Ethology and Behavioral Ecology of Sea Otters and Polar Bears by Randall W. Davis,Anthony M. Pagano Pdf
Sea otters and polar bears are carnivorous marine mammals that still resemble their terrestrial ancestors. Compared with Cetacea (whales and dolphins), Sirenia (dugongs and manatees), and Pinnipedia (seals, sea lions, and walrus), they are less adapted for an aquatic life and the most recently evolved among marine mammals. Sea otters are amphibious but seldom come ashore, and polar bears primarily occur on sea ice or along the shore. When at sea, both species spend most of their time swimming at the surface or making short, shallow dives when foraging or pursuing prey. Indeed, polar bears rarely pursue seals in water. Nevertheless, polar bears are powerful swimmers and will stalk seals from the water. As with many other large carnivores, they are solitary hunters. Although sea otters are gregarious and form aggregations at sea called rafts, they are primarily asocial. Except during mating, the principal interaction among sea otters occurs between a female and offspring during the six-month dependency period. In large carnivores (e.g., wolves and lions) that feed on ungulates, sociality and cooperation are favored because of the need to capture large prey and defend carcasses. Polar bears, which are the largest terrestrial carnivore, are solitary hunters of seals and are neither gregarious nor social. Males and females briefly associate during courtship and mating. During this time, males aggressively compete for females. At other times, males generally avoid each other except for aggregations of males that form while summering on land, and females with cubs avoid males, which are known for infanticide. As with sea otters, the interaction of polar bears outside of mating occurs between a female and her offspring during the 2-3 year dependency period. This interaction is critically important when altricial cubs are born in the winter den. This book provides new insight into the ethology and behavioral ecology of sea otters and polar bears. Each chapter reviews the discoveries of previous studies and integrates recent research using new techniques and technology. The authors also address historic and current anthropogenic challenges for their survival as climate change alters entire marine ecosystems.
