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.

Available in PDF, EPUB and Kindle. Book excerpt: Bering Glacier is the largest surging glacier in the world, having surged at least six times in the last 150 years. With the glacier advancing and retreating as much as 10 km over a surge cycle, it is one of the most physically and biologically dynamic places on Earth. This monograph presents the results of a comprehensive and diverse series of field studies and science investigations at Bering Glacier. The results reported are from a wide range of disciplines, including glaciology, geology, paleogeology, hydrology, limnology, oceanography, tectonics, geomorphology, geophysics, meteorology, remote sensing, climate change, anthropology, and ecological studies pertaining to vegetation, fish, and marine mammals. The compilation of these individual studies into a single publication allows for a more complete understanding of how the approximately 5,000 km2 Bering Glacier system plays a major role in the greater southeastern coastal region of Alaska and through its wastage, its impact on the circulation of the northeast Pacific Ocean and on the global sea level.

This book was released on 2011 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The diet of harbor seals (Phoca vitulina richardii) in San Francisco Bay (SFB) in California was examined from July 2007 to July 2008 via scat analysis. Scats were collected from five major haul-out sites; 22 species of fish and one species of crustacean were identified from 422 scats. The reliance of a non-native invasive species, Yellowfin Goby (Acanthogobius flavimanus), increased in importance in the diet. Additionally, another non-native invasive fish species, Chameleon Goby (Tridentiger trigonocephalus), was found for the first time in the diet of harbor seals in SFB. Harbor seal diet was compared between seasons, locations, and years using Spearman's rank correlations; diet was statistically different between years (1991-1992 and 2007-2008), between the pupping and non-pupping seasons, and between North SFB and South SFB haul-out locations. California Department of Fish and Game (CDFG) trawl data were also compared to harbor seal diet data and were found to be significantly correlated.
