On the cusp of adulthood, Meeka is about to confront a clash of lifestyles and cultures as she leaves her community in Canada's Far North and begins her education in the South. Being a teenager in Nunavut comes with its own challenges, but as a daughter of an Inuk hunter, Meeka has enjoyed a certain status in her community. Now Meeka goes from being a community leader to a meek student as she is lured into the harsh complexities of navigating a university town. Born in Polar's Den is a coming-of-age novel that unapologetically explores the social, political and demographic issues surrounding Canada's Arctic region and its aboriginal peoples. The author's interest in Inuit culture shines through as he examines the experiences of Nunavut's young people in their transition to adulthood in a modern age....
Ethology and Behavioral Ecology of Sea Otters and Polar Bears by Randall W. Davis,Anthony M. Pagano Pdf
Sea otters and polar bears are carnivorous marine mammals that still resemble their terrestrial ancestors. Compared with Cetacea (whales and dolphins), Sirenia (dugongs and manatees), and Pinnipedia (seals, sea lions, and walrus), they are less adapted for an aquatic life and the most recently evolved among marine mammals. Sea otters are amphibious but seldom come ashore, and polar bears primarily occur on sea ice or along the shore. When at sea, both species spend most of their time swimming at the surface or making short, shallow dives when foraging or pursuing prey. Indeed, polar bears rarely pursue seals in water. Nevertheless, polar bears are powerful swimmers and will stalk seals from the water. As with many other large carnivores, they are solitary hunters. Although sea otters are gregarious and form aggregations at sea called rafts, they are primarily asocial. Except during mating, the principal interaction among sea otters occurs between a female and offspring during the six-month dependency period. In large carnivores (e.g., wolves and lions) that feed on ungulates, sociality and cooperation are favored because of the need to capture large prey and defend carcasses. Polar bears, which are the largest terrestrial carnivore, are solitary hunters of seals and are neither gregarious nor social. Males and females briefly associate during courtship and mating. During this time, males aggressively compete for females. At other times, males generally avoid each other except for aggregations of males that form while summering on land, and females with cubs avoid males, which are known for infanticide. As with sea otters, the interaction of polar bears outside of mating occurs between a female and her offspring during the 2-3 year dependency period. This interaction is critically important when altricial cubs are born in the winter den. This book provides new insight into the ethology and behavioral ecology of sea otters and polar bears. Each chapter reviews the discoveries of previous studies and integrates recent research using new techniques and technology. The authors also address historic and current anthropogenic challenges for their survival as climate change alters entire marine ecosystems.

Do you like polar bears? Do you want polar bears to be around in 50 years? Do you think that climate change is the only major threat to polar bear survival? Do you believe that polar bears are adequately protected today? Would you like to contribute to saving polar bears today and in the future? If your answer to any of those questions is yes, you need to read this book. "This book is an eye-opener and should kick off extensive debates."Dr. Thor S. Larsen, professor emeritus, Member of the IUCN Polar Bear Specialist Group 1968-1985. "In this impassioned book Morten raises very important, provocative questions that are not being addressed by the international environmental groups." Art Wolfe, Award-winning conservation photographer. In this book, the author analyses the current status of the polar bear. And he punctures the myth that polar bears are well protected and managed today. While most people think that global warming is the overhanging threat to polar bear survival, the author documents that it is actually the continuation of an unsustainable hunting pressure that is driving the species towards extinction. Across 228 pages, interspersed with beautiful photographs, Morten Joergensen demonstrates how there are probably fewer polar bears than most authorities claim, how hunting is the greatest manageable threat to the species, how current protection measures are insufficient, how the animal has been commercialized and how lack of courage and honesty is allowing this scenario to continue. The book also contains a long string of realistic and very urgent recommendations for action - to save polar bears before they are gone forever.
Screening the Single Euploid Embryo by E Scott Sills Pdf
Intended for readers with a background in fertility medicine as well as those less familiar with IVF, this comprehensive work presents an update on preimplantation genetic testing to enable single embryo transfer (SET). An international cast of contributors explains the treatment sequence—from ovulation induction to luteal support—aiming to transfer only one euploid embryo. Applications of molecular techniques for gamete and embryo assessment are fully detailed, with a focus on the strengths and limitations of each. In addition, expert commentary is shared across a range of regulatory challenges associated with embryo screening and cryopreservation. As access to advanced reproductive technology increases against a sharper background of healthcare reform, clinicians, economists, bioethicists and legislators alike will find this new volume relevant and highly accessible.

Polar Bears by IUCN/SSC Polar Bear Specialist Group. Working Meeting Pdf
These proceedings provide an overview of the ongoing research and management activities on polar bears in the circumpolar arctic. Together with the previous 13 proceedings, they provide an historic record of international efforts in protecting, studying and managing polar bears. With recent documentation of how warmer arctic climate might affect the sea ice habitat of polar bears, the predictions of even warmer climate in the next decades, and documentation of effects on polar bears subpopulations, an evaluation of the red list status of polar bear subpopulations was followed by an increased conservation designation of vulnerable. In the complexity of possible interactions between climate change, local harvest, and in some areas high levels of pollutants, an increased level of international cooperation was advocated.
