| diagram of a sea otter: The Ecology of Place Ian Billick, Mary V. Price, 2012-08-01 Ecologists can spend a lifetime researching a small patch of the earth, studying the interactions between organisms and the environment, and exploring the roles those interactions play in determining distribution, abundance, and evolutionary change. With so few ecologists and so many systems to study, generalizations are essential. But how do you extrapolate knowledge about a well-studied area and apply it elsewhere? Through a range of original essays written by eminent ecologists and naturalists, The Ecology of Place explores how place-focused research yields exportable general knowledge as well as practical local knowledge, and how society can facilitate ecological understanding by investing in field sites, place-centered databases, interdisciplinary collaborations, and field-oriented education programs that emphasize natural history. This unique patchwork of case-study narratives, philosophical musings, and historical analyses is tied together with commentaries from editors Ian Billick and Mary Price that develop and synthesize common threads. The result is a unique volume rich with all-too-rare insights into how science is actually done, as told by scientists themselves. |
| diagram of a sea otter: Sea Otter Conservation Shawn Larson, James L. Bodkin, Glenn R VanBlaricom, 2014-12-23 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 |

| diagram of a sea otter: Human Impacts on Ancient Marine Ecosystems Torben C. Rick, Jon M. Erlandson, 2008-04-29 Archaeological data now show that relatively intense human adaptations to coastal environments developed much earlier than once believed—more than 125,000 years ago. With our oceans and marine fisheries currently in a state of crisis, coastal archaeological sites contain a wealth of data that can shed light on the history of human exploitation of marine ecosystems. In eleven case studies from the Americas, Pacific Islands, North Sea, Caribbean, Europe, and Africa, leading researchers working in coastal areas around the world cover diverse marine ecosystems, reaching into deep history to discover how humans interacted with and impacted these aquatic environments and shedding new light on our understanding of contemporary environmental problems. |

| diagram of a sea otter: Morphology of the Auditory and Vestibular Organs in Mammals, with Emphasis on Marine Species Galina Nikolaevna Solnt︠s︡eva, 2007 This monograph describes the directions of the structural evolution of the peripheral part of the auditory system in representatives of different ecological groups of mammals. Special attention is paid to the least studied orders of marine mammals (pinnipeds, cetaceans), being of great interest both with regards to the echolocating abilities in dolphins and the influence of the aquatic environment on the development of morphological adaptations in the structure of the outer, middle and inner ears. Undertaken for the first time, a comparative embryological study of the peripheral part of the auditory system in marine mammals allowed the author to reveal the developmental pattern of the auditory and equilibrium organs in animals with a different auditory specialization. The influence of ecological factors on the adaptive trait development in the structural organization of the outer, middle and inner ears in semi-aquatic and aquatic species is discussed. The book is illustrated with a large number of high-quality micro-photos.--Jacket |

| diagram of a sea otter: Dinghy Drop Tom Docherty, 2007-03-29 September 1941 approval was given for the formation of two long-range Air-Sea Rescue squadrons. No 279 Squadron was formed at Bircham Newton in Norfolk. In the period leading up to the formation of the squadron there had been much work done in relation to air-dropped survival equipment such as the Lindholme Dinghy Dropping Gear, the Bircham Barrel and the Thornaby Bag. These contained such items as water, food, first-aid kits and distress signals. 279 was the first squadron to employ the airborne lifeboat, which was carried beneath the bellies of the portly Hudson. In January 1942 a practical boat, fitted with oars, sails and engines was put into production with the intention of slinging it under the bomb bay of the Hudson and to drop it by parachute. In October 1944 the Squadron re-equipped with Warwick Mk I aircraft moved to Thornaby in the NE of England. By now its ASR net was cast wide and there were detachments at Tain, Fraserburgh, Wick and Banff (all in northern Scotland) and Reykjavik. |

| diagram of a sea otter: Biology of Marine Mammals John E. Reynolds, 2013-08-06 Taking an integrated approach to the biology of marine carnivores, cetaceans, and sirenians, twenty-two prominent researchers compare marine mammals with one another and with terrestrial mammals, providing a framework for fundamental biological and ecological concepts. They describe functional morphology, sensory systems, energetics, reproduction, communication and cognition, behavior, distribution, population biology, and feeding ecology. They also detail the physiological adaptations—for such activities and processes as diving, thermo-regulation, osmoregulation, and orientation—that enable marine mammals to exploit their aquatic environment. |
| diagram of a sea otter: Food Webs and the Dynamics of Marine Reefs Tim McClanahan, George Branch, 2008-04-16 Biologists have made significant advances in our understanding of the Earth's shallow subtidal marine ecosystems, but the findings on these disparate regions have never before been documented and gathered in a single volume. Now, in Food Webs and the Dynamics of Marine Reefs, Tim R. McClanahan and George M. Branch fill this lacuna with a comparative and comprehensive collection of nine essays written by experts on specific aquatic regions. Each essay focuses on the food webs of a respective ecosystem and the factors affecting these communities, from the intense and direct pressure of human influence on fisheries to the multi-vector contributors to climate change. The book covers nine shallow water marine ecosystems from selected areas throughout the world: four coral reef systems, three hard bottom systems, and two kelp systems. In summarizing their organization, human influence on them, and recent developments in these ecosystems, the authors contribute to our understanding of their ecological organization and management. Food Webs and the Dynamics of Marine Reefs will be a useful tool for all benthic marine investigators, providing an expert, comparative view of these aquatic regions. |

| diagram of a sea otter: Modeling Life Alan Garfinkel, Jane Shevtsov, Yina Guo, 2017-09-06 This book develops the mathematical tools essential for students in the life sciences to describe interacting systems and predict their behavior. From predator-prey populations in an ecosystem, to hormone regulation within the body, the natural world abounds in dynamical systems that affect us profoundly. Complex feedback relations and counter-intuitive responses are common in nature; this book develops the quantitative skills needed to explore these interactions. Differential equations are the natural mathematical tool for quantifying change, and are the driving force throughout this book. The use of Euler’s method makes nonlinear examples tractable and accessible to a broad spectrum of early-stage undergraduates, thus providing a practical alternative to the procedural approach of a traditional Calculus curriculum. Tools are developed within numerous, relevant examples, with an emphasis on the construction, evaluation, and interpretation of mathematical models throughout. Encountering these concepts in context, students learn not only quantitative techniques, but how to bridge between biological and mathematical ways of thinking. Examples range broadly, exploring the dynamics of neurons and the immune system, through to population dynamics and the Google PageRank algorithm. Each scenario relies only on an interest in the natural world; no biological expertise is assumed of student or instructor. Building on a single prerequisite of Precalculus, the book suits a two-quarter sequence for first or second year undergraduates, and meets the mathematical requirements of medical school entry. The later material provides opportunities for more advanced students in both mathematics and life sciences to revisit theoretical knowledge in a rich, real-world framework. In all cases, the focus is clear: how does the math help us understand the science? |

| diagram of a sea otter: Biodiversity and Environmental Conservation Justice Ross & Roberto Adkins, 2018-10-09 Biodiversity is the variety of all the genes, species and ecosystems which are found on our planet. It provides humanity with the cornucopia of goods and services, from food, energy and materials to the genes which protect our crops and cure our diseases. The loss of the earth's biological diversity is one of the most pressing environmental and development issues. Sustainability highlights the idea that the current use of natural resources should not diminish the options of future generations, and maintaining biodiversity is clearly one of the requirements for meeting this goal. Biodiversity conservation addresses the remarkable growth in concern at all levels for living things and the environment, and increased appreciation of the links between the state of ecosystems and the state of humankind. Building on a wealth of research and analysis by the conservation community worldwide, this book provides a comprehensive and accessible view of key global issues in biodiversity. It outlines some of the broad ecological relationships between humans and the rest of the material world and summaries information on the health of the planet. Biodiversity is beneficial to the local environment, and can also be a natural form of crop protection. In conventional agriculture, biodiversity is often eliminated by planting large tracts of fields with a single crop, and killing other species with herbicides, insecticides, pesticides, and fungicides. In the absence of biodiversity, the arrival of a single species can significantly affect crop production, and conventional farmers counter this with chemical killing agents that damage the environmental health of the area. Conservation is the protection, preservation, management, or restoration of wildlife and natural resources such as forests and water. Through the conservation of biodiversity and the survival of many species and habitats which are threatened due to human activities can be ensured. There is an urgent need, not only to manage and conserve the biotic wealth, but also restore the degraded ecosystems. This book will definitely serve as an excellent reference material and practical guide for teachers, research workers, students and environmentalists. |
| diagram of a sea otter: Conservation of Wildlife Populations L. Scott Mills, 2012-12-17 Population ecology has matured to a sophisticated science with astonishing potential for contributing solutions to wildlife conservation and management challenges. And yet, much of the applied power of wildlife population ecology remains untapped because its broad sweep across disparate subfields has been isolated in specialized texts. In this book, L. Scott Mills covers the full spectrum of applied wildlife population ecology, including genomic tools for non-invasive genetic sampling, predation, population projections, climate change and invasive species, harvest modeling, viability analysis, focal species concepts, and analyses of connectivity in fragmented landscapes. With a readable style, analytical rigor, and hundreds of examples drawn from around the world, Conservation of Wildlife Populations (2nd ed) provides the conceptual basis for applying population ecology to wildlife conservation decision-making. Although targeting primarily undergraduates and beginning graduate students with some basic training in basic ecology and statistics (in majors that could include wildlife biology, conservation biology, ecology, environmental studies, and biology), the book will also be useful for practitioners in the field who want to find - in one place and with plenty of applied examples - the latest advances in the genetic and demographic aspects of population ecology. Additional resources for this book can be found at: www.wiley.com/go/mills/wildlifepopulations. |

| diagram of a sea otter: The Secret Life of Sharks A. Peter Klimley, 2008-06-17 Marine biologist Pete Klimley swims with the sharks. He was one of the first scientists to free-dive among sharks, and he has spent nearly thirty years studying shark behavior, sometimes swimming in schools of several hundred sharks. From his firsthand observations he has learned that sharks are not the vicious man-eaters that we imagine, but fascinating animals with complex behaviors. Most people who think of sharks at all think immediately of great white sharks. But there are more than four hundred species of shark. Dr. Klimley has studied several species, most notably the great white and the hammerhead. (He describes the great white as the athlete among sharks, and the hammerhead as the Ph.D. of the shark world.) In The Secret Life of Sharks Dr. Klimley reveals the significant discoveries he made about hammerhead navigation and great white eating habits. By studying hammerheads gathered around underwater seamounts, Dr. Klimley learned that hammerheads rely on sophisticated tracking of ocean-floor magnetism to navigate. His long-term study of great white sharks off the California coast demonstrated that these huge sharks prefer to eat seals and sea lions because of the energy contained in their fatty bodies. They are selective eaters, not the man-eaters we expect, and they sometimes go weeks between meals. But Dr. Klimley did observe a ritualized behavior that great whites practice in order to avoid deadly disputes over prey that one shark has captured and another wants. Although we have learned a great deal about shark behavior, says Dr. Klimley, there is much that we do not know. Unfortunately we are destroying these magnificent creatures of the deep through overfishing and degradation of the oceans. Already some populations of sharks have declined steeply. Vividly written by one of the foremost authorities on sharks, The Secret Life of Sharks is a fascinating account of some of the world's most magnificent animals. |
