Download or read book Photoperiod and the Timing of Pupping in the Pacific Harbor Seal Phoca Vitulina Richardsi with Notes on Reproduction in Northern Fur Seals and Dall Porpoises written by Jonathan L. Temte and published by . This book was released on 1985 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birth and pupping season records of Pacific harbor seals (Phoca vitulina richardsi) were used in an analysis of photoperiod effect on the timing of birth in this species. Dates and latitudes of births were converted into photoperiods using a photoperiod equation. Sequential dates from parturition were converted into photoperiods and plotted as a function of latitude. The resulting functions of latitude vs. photoperiod were regressed to determine the point during the reproductive cycle at which latitude did not have an effect on photoperiod. The Pacific harbor seal can be divided into two geographic subgroups by their respective pupping seasons. Seals inhabiting the Puget Sound / Strait of Georgia (PS/SG) System give birth to pups an average of 88 days (P

This book was released on 2012-12-06 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thougtit that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 31 (thesis year 1986) a total of 11 ,480 theses titles trom 24 Canadian and 182 United States universities. We are sure that this broader base tor these titles reported will greatly enhance the value ot this important annual reterence work. While Volume 31 reports theses submitted in 1986, on occasion, certain univer sities do re port theses submitted in previousyears but not reported at the time.

This book was released on 2013-09-13 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacific harbor seals (Phoca vitulina richardsi) are the dominant and only year-round resident pinniped in the San Francisco Bay Area, California. Long-term monitoring studies have been conducted at the largest harbor seal colonies in Point Reyes National Seashore since the mid 1970's. The objectives of monitoring each site and the population as a whole are to i) detect changes in population size, ii) detect changes in reproductive success by way of pup production, and iii) identify anthropogenic or environmental factors that may affect the condition of the population (Adams et al. In Prep).
