Download or read book Ethology and Behavioral Ecology of Phocids written by Daniel P. Costa and published by Springer Nature. This book was released on 2022-03-17 with total page 651 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phocid (or earless or true) seals are ecologically diverse, occupying habitats from the tropics to the poles in marine and freshwater and feeding on anything from tiny zooplankton to other marine mammals. There are 18 species of phocid seals, the smallest species (ringed seal) is more than 20 times smaller than the largest (southern elephant seal), with marked sexual dimorphism present in some species. This book examines the behavior, ecology, and physiology that allow phocid seals to inhabit such a wide range of habitats. The book is composed of 16 chapters written by 37 authors from 8 countries. The book first describes the general patterns of phocid behavior, followed by descriptions of what is known about well-studied species. We have taken a holistic approach, focusing not only on the behaviors themselves but also on the factors that constrain the expression of behavior and the proximate mechanisms driving behavior. In many cases, the chapters represent collaborations between well-established researchers and early-mid career individuals who bring new perspectives to help carry the field of phocid behavioral ecology well into the future.

This book was released on 2000 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Marine Fisheries Service (l\rNßS) conducted an aerial survey of the beluga whale population in Cook Inlet, Alaska, during 8-14 June 1999. The 41.5 hr surveywas flown in a twin-engine, high-wing aircraft at an altitude of 244 m (800 ft) and speed of 185 km/hr (100 kt) along a trackline 1.4 km from shore, consistent with annual surveys flown each year since 1993. The flights in 1999 included one or more surveys of coastal areas around nearly the entire Inlet and 1,790 km oftransects across the Inlet. Paired, independent observers searched on the coastal (left) side of the plane, where virtually all sightings occur, while a single observer and a computer operatorldatarecorder were on the right side. In addition, each day a different visitor observed from the left side. After finding beluga groups, a series of aerial passes were made to allow at least two pairs of primary observers to make four or more counts of each group. Inter-day counts ranged from 75 to160 belugas near the Susitna River (between the Beluga and Little Susitna Rivers), 13 to 43 in Knik Arm, and 17 to 30 in Chickaloon Bay, but no belugas were found in lower Cook Inlet. The sum of the aerial estimates (using median counts from each site, not corrected for missed whales) ranged from 197 to 221 whales, depending on observer. The index count for 1999 is 217 , which is slightly higher than the index counts for 1998 (193) but lower than all index counts by NMFS observers between 1993-97

Available in PDF, EPUB and Kindle. Book excerpt: In recent years an increasing number of studies have been published reporting observations of adapted behaviour and shifting species ranges of plant and animal species due to recent climate warming. Are these `fingerprints' of climate change? An international conference was organised to bring together scientists from different continents with different expertise but sharing the same issue of climate change impact studies. Ecologists, zoologists, and botanists exchanged and discussed the findings from their individual field of research. The present book is an international collection of biological signs of recent climate warming, neither based only on computer models nor on prediction for the future, but mainly on actually occurring changes in the biosphere such as adapted behaviour or shifts in the ranges of species. `Fingerprints' of Climate Change presents ecological evidence that organisms are responding to recent global warming. The observed changes may foreshadow the types of impacts likely to become more frequent and widespread with continued warming.

Download or read book The Pacific Arctic Region written by Jacqueline M. Grebmeier and published by Springer. This book was released on 2014-06-10 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Pacific Arctic region is experiencing rapid sea ice retreat, seawater warming, ocean acidification and biological response. Physical and biogeochemical modeling indicates the potential for step-function changes to the overall marine ecosystem. This synthesis book was coordinated within the Pacific Arctic Group, a network of international partners working in the Pacific Arctic. Chapter topics range from atmospheric and physical sciences to chemical processing and biological response to changing environmental conditions. Physical and biogeochemical modeling results highlight the need for data collection and interdisciplinary modeling activities to track and forecast the changing ecosystem of the Pacific Arctic with climate change.
