Book Description
Research in whale origins is now in an explosive phase, with a cascade of discoveries adding to our understanding of the evolutionary pattern and a suite of new techniques being applied to address new questions. The objective of this volume is to provide a snapshot of this explosion. The volume paints the scene with a broad brush. Taken together the chapters clearly indicate that cetacean origins is a field that is dynamic, multidisciplinary, and that the end of the explosive phase is not in sight.

Book Description
"A ... first-person account of the discoveries that brought to light the early fossil record of whales. As evidenced in the record, whales evolved from herbivorous forest-dwelling ancestors that resembled tiny deer to carnivorous monsters stalking lakes and rivers and to serpentlike denizens of the coast. Thewissen reports on his discoveries in the wilds of India and Pakistan, weaving a narrative that reveals the day-to-day adventures of fossil collection, enriching it with local flavors from South Asian culture and society"--Dust jacket flap.

Book Description
Based on actual data of Soviet whaling, and reliable methodologies that existed at the time when this monograph was written, it examines the distribution and migration patterns of whales of the Southern Ocean. It defines distinct populations on the basis of phenes, as well as whale breeding zones, which are located in the adjacent to the Southern Ocean waters at lower latitudes. The book records the presence of a new species of killer whale in the Southern Ocean - Orcinus nana. Prenatal growth patterns, pregnancy and lactation duration, mean sizes of new-born whales are determined. Methods for the graphic recording of registering structures are described, and an original method for their decoding is proposed to determine animal age. The age of sexual and physical maturity, life expectancy is determined. Earlier unknown “pair formations” on the lower jaw of baleen whales and sperm whales are described, together with their macro, histological and electronic microscopic structure. The impact of the extermination of whales on the Southern Ocean ecosystem is examined, recommendations for control of the current state of whale populations are given, and perspectives of whale population recovery are estimated. Regions that could be used as testing areas for whale registration method are defined. The book is intended for biologist-cytologists, ecologists and other specialists interested in cetaceans, and for biology students.

Book Description
With their haunting ocean "songs" and gushing spouts, whales great or small inspire awe. Though their impressive size and might protect them from most natural dangers, intensive hunting by humans has put them right at the top of the conservation agenda. This wonderfully illustrated guide covers classification of all the whale families: blue whales (the world's largest mammals), magnificent humpbacks, sperm whales, and right whales, as well as dolphins and other cetaceans. A uniquely informed text written by a world expert accompanies a wide range of photographs and illustrations of whales leaping, blowing, and swimming. Realistically examine the implications of the commercial exploitation of whales and dolphins. Dramatic stories of whale hunts from the past give the history behind the present-day problems. Information on the dolphin's high intelligence and gentleness make these playful beings all the more endearing. You'll see clearly why they deserve our protection and respect!

Book Description
“A palaeontological howdunnit…[Spying on Whales] captures the excitement of…seeking answers to deep questions in cetacean science.” —Nature Called “the best of science writing” (Edward O. Wilson) and named a best book by Popular Science, a dive into the secret lives of whales, from their four-legged past to their perilous present. Whales are among the largest, most intelligent, deepest diving species to have ever lived on our planet. They evolved from land-roaming, dog-sized creatures into animals that move like fish, breathe like us, can grow to 300,000 pounds, live 200 years and travel entire ocean basins. Whales fill us with terror, awe, and affection--yet there is still so much we don't know about them. Why did it take whales over 50 million years to evolve to such big sizes, and how do they eat enough to stay that big? How did their ancestors return from land to the sea--and what can their lives tell us about evolution as a whole? Importantly, in the sweepstakes of human-driven habitat and climate change, will whales survive? Nick Pyenson's research has given us the answers to some of our biggest questions about whales. He takes us deep inside the Smithsonian's unparalleled fossil collections, to frigid Antarctic waters, and to the arid desert in Chile, where scientists race against time to document the largest fossil whale site ever found. Full of rich storytelling and scientific discovery, Spying on Whales spans the ancient past to an uncertain future--all to better understand the most enigmatic creatures on Earth.

Book Description
From the bestselling author of the The House of God comes an ambitious novel about the complicated relationships between mothers and sons, doctors and patients, the past and the present, and love and death... Settled into a relationship with an Italian yoga instructor and working in Europe, Dr. Orville Rose's peace is shaken by his mother's death. On his return to Columbia, a Hudson River town of quirky people and “plagued by breakage,” he learns that his mother has willed him a large sum of money, her 1981 Chrysler, and her Victorian house in the center of town. There's one odd catch: he must live in her house for one year and thirteen days. As he struggles with his decision—to stay and meet the terms of the will or return to his life in Italy—Orville reconnects with family, reunites with former friends, and comes to terms with old rivals and bitter memories. In the process he’ll discover his own history, as well as his mother’s, and finally learn what it really means to be a healer, and to be healed.
