Available in PDF, EPUB and Kindle. Book excerpt: It is not possible to survey the entire harp seal (Pagophilus groenlandicus) population, but the number of pups born in a year can be estimated via aerial surveys conducted in the spring, when the seals gather on the ice to have their pups. This information is incorporated in a population model that also integrates information on age specific reproductive rates and total removals from the population, including animals that have been killed but not recovered. This report presents an estimate of total population of northwest Atlantic harp seals based on aerial surveys carried out in 2004.

Available in PDF, EPUB and Kindle. Book excerpt: When I first proposed a series entitled Current Mammalogy to the pub lishers, they were reluctant to undertake such a project because they viewed the field of mammology as overly fragmented. At first I found this idea to be difficult to accept; however, upon reflection, I came near to agreeing with it. Although many of us work on mammals, we gen erally feel more allegiance to our specialties, such as systematics, ge netics, cytogenetics, ecology, behavior, pest control, paleontology, wildlife management, primatology, and marine mammalogy, than we do to the general field of mammalogy. However, rather than becoming discour aged from pursuing this project, I became more certain than ever that a series such as Current Mammalogy was needed. We hope to make this series a place where specialists can present their ideas not only to other members of their specialty, but to those outside the area as well. Hopefully, this exchange of ideas will be a mutually beneficial exercise. The Editorial Board of Current Mammalogy has decided to keep the range of subjects in each volume as broad as possible rather than concentrating on one or two topics, in the hope that this will keep the series as useful as possible to the broadest range of readers.

This book was released on 2013 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: A population model was used to examine changes in the size of the Northwest Atlantic harp seal population between 1952 and 2012. The model incorporated information on reproductive rates, reported removals, estimates of non-reported removals and losses through bycatch in other fisheries to determine the population trajectory. The model was fit to eleven periodic estimates of pup production from 1952 to 2008, and to annual pregnancy rate data collected between 1954 and 2012. The harp seal (Pagophilus groenlandicus) assessment incorporates information on annual age specific reproductive rates, reported harvests, struck and loss, and ice-related mortality of young of the year (YOY), into an age-structured model to estimate total population size. The model is fitted to estimates of pup production obtained from aerial surveys and mark-recapture studies by adjusting the initial population size in 1952 and adult mortality rates.--Document.
