Download or read book Wild Blue written by Dan Bortolotti and published by Macmillan. This book was released on 2008-10-14 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: The blue whale holds the title of largest creature that has ever lived, and it may also be the most mysterious. The biggest blue whales can outweigh every player in Major League Baseball and the National Hockey League combined. Their mouths can gulp more than thirteen thousand gallons of seawater. A newborn can be over twenty feet long and gain nearly twenty tons in seven months—about eight pounds per hour. Blue whales emit more powerful sounds than any other animal on earth, though many of their vocalizations are beyond the range of human hearing. Yet nearly everything that we have learned about blue whales has come after humans almost wiped them out from the oceans. A century ago, some three hundred thousand roamed the seas. But in the first decades of the twentieth century, humans hunted and killed 99.9% of them. Their numbers decimated, the species seemed destined for extinction. Only in recent years has the number slowly begun to increase, along with hope for the blue whale's future. Equal parts history and science, Wild Blue is the first comprehensive portrait of the blue whale. It draws upon new findings from scientists who have begun to identify individual blue whales and understand how they dive, how they feed, where they migrate, and why they emit their haunting, low-frequency calls. With deft, poignant writing, Dan Bortolotti gives us the most vibrant, breathtaking view to date of these magnificent creatures.

Available in PDF, EPUB and Kindle. Book excerpt: "The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) assessed the Atlantic blue whale (Balaenoptera musculus) population as Endangered in 2002, and reaffirmed this status in 2012. The Species at Risk Program has requested Science advice on available information and the current state of knowledge about the habitat of blue whales in the northwest Atlantic. Specifically, the best available information on the habitat requirements of the population was requested, including a description of the habitat properties needed for successful completion of the life cycle processes necessary for survival and recovery of blue whales, a description of the functions, features and attributes of this habitat, the spatial extent of the areas likely to have these habitat properties, and the activities likely to destroy these habitat properties in the areas identified"--Context, p.

Download or read book A Primer of Life Histories written by Jeffrey A. Hutchings and published by Oxford University Press. This book was released on 2021-09-15 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life histories can be defined as the means by which individuals (or more precisely genotypes) vary their age- or stage-specific expenditures of reproductive effort in response to genetic, phenotypic, and environmental correlates of survival and fecundity. Life histories reflect the expression of traits most closely related to individual fitness, such as age and size at maturity, number and size of offspring, and the timing of the expression of those traits throughout an individual's life. In addition to addressing questions of fundamental importance to ecology and evolution, life-history research plays an integral role in species conservation and management. This accessible primer encompasses the basic concepts, theories, and applied elements of life history evolution, including patterns of trait variability, underlying mechanisms of plastic/evolutionary change, and the practical utility of life-history traits as metrics of species/population recovery, sustainable exploitation, and risk of extinction. Empirical examples are drawn from the entire spectrum of life. A Primer of Life Histories is designed for readers from a broad range of academic backgrounds and experience including graduate students and researchers of ecology and evolutionary biology. It will also be useful to a more applied audience of academic/government researchers in fields such as wildlife biology, conservation biology, fisheries science, and the environmental sciences.
