Pages : 98
Book Description
This book focuses on transient killer whales. Enigmatic and elusive, these mammal-hunting whales are difficult animals to study. They travel in small groups, often moving unpredictably, which makes them less conspicuous than the larger resident pods. For these and other reasons, our understanding of the life history and ecology of transient killer whales has lagged behind that of residents. Transients contains the latest information on the natural history of transient killer whales, including their feeding habits, social lives, and distribution patterns. The catalogue section contains photographs of and notes on over 200 individual whales. Numerous sidebars contain interesting observations on encounters with transients as well as information on how and where to best watch them.
Hotspots and Behavioral Patterns of Southern Alaska Resident Killer Whales (Orcinus Orca)

Book Description
The resident killer whale (Orcinus orca) is a genetically and behaviorally distinct ecotype of killer whale that feeds primarily on Pacific salmon (Oncorhynchus spp.). Long-term monitoring over 30 years of study has enabled detailed investigation into pod-specific, seasonal, and compositional differences in space use and behavior. To investigate use of habitat, 33 resident killer whales representing 14 pods in the northern Gulf of Alaska were tagged with satellite transmitters during all years from 2006 to 2014, and transmissions were received during the months of June to January. Core use areas were identified through utilization distributions using a biased Brownian Bridge movement model. Tagging results indicate different core use areas between pods, which could be due to cultural transmission within matrilineal groups. To investigate differences in behavior, 1337 hours of behavioral data were collected from 2006 to 2015. For these observations, chi squared tests were used to determine significant differences in behavior budgets between seasons, regions, haplotypes, and numbers of pods. The presence of 'rarely sighted' pods (sighted in less than 5% of encounters) had a large influence on the frequency of social behavior, which increased from 18.5% without their presence to 31.4% with it (X2 = 17.3, df = 1, P

Into Great Silence
Author: Eva SaulitisPublisher: Beacon Press
ISBN: 0807014362
Category : Nature
Languages : en
Pages : 274
Book Description
Science entwines with matters of the human heart as a whale researcher chronicles the lives of an endangered family of orcas Ever since Eva Saulitis began her whale research in Alaska in the 1980s, she has been drawn deeply into the lives of a single extended family of endangered orcas struggling to survive in Prince William Sound. Over the course of a decades-long career spent observing and studying these whales, and eventually coming to know them as individuals, she has, sadly, witnessed the devastation wrought by the Exxon Valdez oil spill of 1989—after which not a single calf has been born to the group. With the intellectual rigor of a scientist and the heart of a poet, Saulitis gives voice to these vital yet vanishing survivors and the place they are so loyal to. Both an elegy for one orca family and a celebration of the entire species, Into Great Silence is a moving portrait of the interconnectedness of humans with animals and place—and of the responsibility we have to protect them.
