Book Synopsis Evidence of Bowhead Whale Feeding Behavior from Aerial Photography by : Julie A. Mocklin
Download or read book Evidence of Bowhead Whale Feeding Behavior from Aerial Photography written by Julie A. Mocklin and published by . This book was released on 2009 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerial photographs of the Bering-Chukchi-Beaufort population of bowhead whales (Balaena mysticetus) were analyzed to investigate their feeding habits, particularly epibenthic feeding near Barrow, Alaska. The analysis was based on mud visible on the dorsal surface of whales, resulting from feeding near the seafloor. A new photographic scoring system was developed and tested by bowhead experts, including subsistence whalers, to ensure an acceptable level of agreement on the analytical method. The tests resulted in > 93% agreement when whales were scored as muddy, and 100% when clean. Over 3,600 photographs were analyzed from 1985, 1986, and 2003-2007, including photos from surveys in spring and late summer and in both the Western and Eastern Beaufort Sea. Of all the photographs analyzed, 64% were scored as definitively muddy. In spring, ratios ranged from a low of 27% in 2003 to a high of 76% in 2004. In May of 1986 and when all four May sample sets off Barrow were combined, there was a significant difference (t-test, P
Book Synopsis Conservation Technology by : Serge A. Wich
Download or read book Conservation Technology written by Serge A. Wich and published by Oxford University Press. This book was released on 2021-08-31 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global loss of biodiversity is occurring at an unprecedented pace. Despite the considerable effort devoted to conservation science and management, we still lack even the most basic data on the distribution and density of the majority of plant and animal species, which in turn hampers our efforts to study changes over time. In addition, we often lack behavioural data from the very animals most influenced by environmental changes; this is largely due to the financial and logistical limitations associated with gathering scientific data on species that are cryptic, widely distributed, range over large areas, or negatively influenced by human presence. To overcome these limitations, conservationists are increasingly employing technology to facilitate such data collection. Innovative solutions have been driven by dramatic advances in the conservation-technology interface. The use of camera traps, acoustic sensors, satellite data, drones, and computer algorithms to analyse the large datasets collected are all becoming increasingly widespread. Although specialist books are available on some of these individual technologies, this is the first comprehensive text to describe the breadth of available technology for conservation and to evaluate its varied applications, bringing together a team of international experts using a diverse range of approaches. Conservation Technology is suitable for graduate level students, professional researchers, practitioners and field managers in the fields of ecology and conservation biology.

This book was released on 2011-08-29 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: With coverage on all the marine mammals of the world, authors Jefferson, Webber, and Pitman have created a user-friendly guide to identify marine mammals alive in nature (at sea or on the beach), dead specimens “in hand , and also to identify marine mammals based on features of the skull. This handy guide provides marine biologists and interested lay people with detailed descriptions of diagnostic features, illustrations of external appearance, beautiful photographs, dichotomous keys, and more. Full color illustrations and vivid photographs of every living marine mammal species are incorporated, as well as comprehendible maps showing a range of information. For readers who desire further consultation, authors have included a list of literature references at the end of each species account. For an enhanced understanding of habitation, this guide also includes recognizable geographic forms described separately with colorful paintings and photographs. All of these essential tools provided make Marine Mammals of the World the most detailed and authoritative guide available! * Contains superb photographs of every species of marine mammal for accurate identification * Authors’ collective experience adds up to 80 years, and have seen nearly all of the species and distinctive geographic forms described in the guide * Provides the most detailed and anatomically accurate illustrations currently available * Special emphasis is placed on the identification of species in “problem groups, such as the beaked whales, long-beaked oceanic dolphin, and southern fur seals * Includes a detailed list of sources for more information at the back of the book.
