This book was released on 2015 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harbor seals have been listed as a species likely to benefit from new Marine Protected Areas (MPAs) in California as part of the Marine Life Protection Act. Whereas seals may experience direct and indirect effects from these MPAs as a whole, the impacts of individual MPAs remains unclear. To support the analysis of the impacts of one new MPA located in South Humboldt Bay (SHB), California, I conducted two studies to measure the site fidelity of individual harbor seals within SHB and to describe the changes in distribution and abundance of hauled-out seals inside and outside the new MPA there. From June 2011 through May 2012, I used radio telemetry to assess site fidelity of 28 individually tagged seals. Most seals had high fidelity (>75%) for SHB haul-outs, indicating that these seals are present enough to potentially benefit from added protection. However, the use of radio telemetry proved difficult and costly for long-term data collection. Therefore, weekly visual surveys were implemented beginning in July 2012 to track the habitat use of all seals hauled-out in SHB. There were significant seasonal differences in seal abundance (ANOVA, F5 = 4.047, p

This book was released on 2001 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Fourteen harbor seals (Phoca vitulina richardsi) from southcentral Prince William Sound (PWS), Alaska, were outfitted with satellite-linked time depth recorders (SDRs) to monitor their movements and diving behavior. I subsequently examined available information on forage fish abundance, composition and distribution to evaluate whether the distribution and diving behaviors of seals corresponded to the seasonal and temporal distribution of their prey. A wide array of forage fishes were seasonally available to PWS harbor seals. Seasonal differences were apparent in depth of dives and distances moved by seals to foraging areas. It is likely that the two were inter-related, as the distant areas used by seals were also the deepest. Seasonal differences in diving depths and localities were likely due to seasonal changes in prey availability. Seals dove deeper and increased foraging ranges in winter, suggesting prey availability in winter may be greatly reduced compared to spring or summer"--Leaf ii.
