Book Description
Management of cetacean populations is a global conservation concern. The North Pacific humpback whale (Megaptera novaeangliae) in Canada is listed as threatened under the Species At Risk Act, and prey reduction has been identified as a threat to this population. I used focal follows of humpback whales and underwater video of herring schools to estimate Pacific herring (Clupea pallasi) consumption by humpback whales in eastern Queen Charlotte Strait, British Columbia. I combined these results with a bioenergetic model to estimate sex- and age-specific annual energetic requirements of humpback whales to determine the proportion of these requirements that are met by herring. Non-reproductive female, pregnant female, and juvenile and adult male humpbacks met over 50% of their estimated energetic requirements by feeding on herring, while juvenile and lactating females met between 25 and 50% of their requirements. These results can lead to improved management decisions for both humpback whales and herring.

Book Description
In Prince William Sound (PWS) in the early 1990s, biomass of an important forage species, Pacific herring (Clupea pallasii), crashed and has since failed to recover. This thesis explores the role that predation by humpback whales (Megaptera novaeangliae) may have in limiting this recovery. This was done by modeling the historic (1980-2009) relationship between these two species using existing data. Mark-recapture estimates of abundance were combined to form the first time series of humpback whale abundance for this area. This time series was then integrated into the age-structured assessment model used by Alaska Department of Fish and Game to manage herring biomass in PWS by adding annual estimates of humpback whale abundance as a covariate to herring mortality. The current (2009) humpback whale population estimate was 191 (SE 32) representing a rate of increase of 4.5% annually. Humpback whale abundance helped to explain variation in mortality of older (ages 5+) herring only, with humpback whales accounting for as much as one-third of all mortality in these ages. However, retrospective analyses of the updated model show that recruitment, and not predation on adult herring, is the most influential factor limiting the recovery of herring in PWS.

Book Description
Study of a population of 461 humpback whales foraging in Prince William Sound, from 2007-2009, whose population was estimated using mark-recapture models. The seasonal movement of these whales into the Sound is largely driven by the movements of adult herring.

Book Description
Set in the background of modern metropolis, the novel delves into the angst and redemption of an international killer who leads an obscure life in the urban hustle and bustle, and who therefore is untouchable by the public discourse. Through the philosophical musings of occupational gains, emotional issues, and logical relations of the world, the book offers a Kafkaesque self-interrogation and a rapidly-pulsating, Dostoevskian reading experience, while its intertextuality of violence and urban glamor allows room for a profusion of vivid characters and various social experiences, turning the book into a kaleidoscopic, contemporary dissection of the daily life of the urban middle class, as well as the social natures of different walks of life. Beneath the dynamic action scenes that quite exhibit a cinematic touch of Takeshi Kitano, the protagonist constantly raises metaphysical questions upon morality and existence, in a brand-new contemporary format.

Book Description
An ode to marine life and the natural world, from the New York Times–bestselling author of The Hidden Life of Owls This “intimate and spirited” essay collection “offers us the whale watch most of us can only dream of” as they reveal the elusive lives of whales in the Pacific Ocean—home to orcas, humpbacks, blue, gray, and sperm whales (Sy Montgomery, author of The Soul of an Octopus). Leigh Calvez has spent a dozen years researching, observing, and probing the lives of the giants of the deep. Here, she relates the stories of nature's most remarkable creatures, including the familial orcas in the waters of Washington State and British Columbia; the migratory humpbacks; the ancient, deep-diving blue whales, the largest animals on the planet. The lives of these whales are conveyed through the work of dedicated researchers who have spent decades tracking them along their secretive routes that extend for thousands of miles, gleaning their habits and sounds and distinguishing peculiarities. Calvez author invites the reader onto a small research catamaran maneuvering among 100-foot long blue whales off the coast of California; or to join the task of monitoring patterns of humpback whale movements at the ocean surface: tail throw, flipper slap, fluke up, or blow. To experience whales is breathtaking. To understand their lives deepens our connection with the natural world.
