Available in PDF, EPUB and Kindle. Book excerpt: "A small group of gray whales, known as the Pacific Coast Feeding Group, or PCFG spends the summer and autumn along the Pacific coast of North America, where they overlap with the Makah Tribe's Usual and Accus tomed (U&A) fishing grounds off the coast of Washington. In 2005, the Makah requested that NOAA/NMFS waive the MMPA take moratorium and adopt regulations that would authorize the tribe to hunt ENP gray whales within their U&A. As part of its review of this proposed hunt, NMFS continues to evaluate information relevant to ENP stock structure a nd status, including the population dynamics of the PCFG. Assessing whether the PCFG is currently at Optimum Sustainable Population (OSP) (i.e., not depleted) was the objective of the analysis described in this report 1. The assessment is based on modifications to an existing population dynamics model used by the International Whaling Commission (IWC) to conduct projections of gray whale abundance. The model is deterministic, age- and sex-structured, and consists of two groups (the 'north' group and the PCFG) , which are assumed to be separate for purposes of the analysis, but with possible immigration between them. Parameter estimation is based on Bayesian methods"--Summary
Book Synopsis Identifying and Comparing Important Areas for Marine Sustainable Use and Conservation by : Sofie Van Parijs
Download or read book Identifying and Comparing Important Areas for Marine Sustainable Use and Conservation written by Sofie Van Parijs and published by Frontiers Media SA. This book was released on 2024-05-24 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean is under increasing threat from the expansion of human activities. The combined impacts of these threats as well as the potential impacts of climate change and ocean acidification have placed thousands of species at risk of extinction, and have impaired the structure, function, productivity and resilience of marine ecosystems. Currently, some parts of the world's oceans are significantly impacted, yet are without any form of effective management. Only a small proportion of the oceans are within protected area systems. Globally, measures are being taken to increase protection and sustainable management, but application is uncoordinated and not always effective. In order to support effective policy action by countries and competent international and regional organizations, it is critical to build a sound understanding of the most ecologically and biologically important ocean areas that support healthy marine ecosystems so that the necessary steps to ensure the long-term function and resilience of these systems can be taken.

Book Synopsis The Gray Whale: Eschrichtius Robustus by : Mary Lou Jones
Download or read book The Gray Whale: Eschrichtius Robustus written by Mary Lou Jones and published by Academic Press. This book was released on 2012-12-02 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Gray Whale: Eschrichtius robustus provides an introduction to the understanding of Eschrichtius robustus or the gray whale. This book explores the life processes, reproduction, and growth of large cetacean populations. Organized into four parts encompassing 25 chapters, this book begins with an overview of the gray whale evolution, fossils, and subfossil remains, range, and systematics in historical times. This text then presents the historical of gray whale exploitation and the economic importance of these whales to humans. Other chapters consider the gray whale migration, abundance, and seasonal distribution in the wake of the California population's recovery from depletion. This book discusses as well the methods used in shore-based censuses during migration and in aerial surveys of gray whales taken on their winter grounds. The final chapter deals with some innovative approaches to the study of free-ranging cetaceans. This book is a valuable resource for anthropologists, paleontologists, biologists, and naturalists.

Download or read book Sex in Cetaceans written by Bernd Würsig and published by Springer Nature. This book was released on 2023-09-25 with total page 613 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sex in Cetaceans provides an up-to-date review of multi-faceted aspects related to mating and reproduction in toothed and baleen whales. This open access book begins with discussions of sexual selection and anatomical traits related to mating and diversity between the sexes. The functions of non-conceptive copulations are reviewed as are different research techniques applied to explore sex in cetaceans. Authors and editors build knowledge of female and male social, mating, and parental strategies and tactics for several specific toothed dolphin/porpoise/whale species and baleen whale species. It concludes with a discussion of potential conservation efforts and ways to help especially beleaguered species and populations the world over. The volume is intended as a major primer of cetacean sex for undergraduate and graduate students, new and established researchers in the field, and the public wishing to learn more.

Book Synopsis Migrating Eastern North Pacific Gray Whale Behavior Compared Over Multiple Timescales by : Regina Anne Guazzo
Download or read book Migrating Eastern North Pacific Gray Whale Behavior Compared Over Multiple Timescales written by Regina Anne Guazzo and published by . This book was released on 2018 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mysticetes (baleen whales) often make long, annual migrations from high latitude summer feeding areas to low latitude wintering areas. Eastern North Pacific gray whales (Eschrichtius robustus) migrate within a few kilometers from shore for most of their route from summer feeding areas in the Bering, Chukchi, and Beaufort Seas to wintering areas in the lagoons along the south-western coast of the Baja California Peninsula in Mexico. This dissertation combines passive acoustic recordings, infrared camera video, and visual sightings to investigate gray whale behavior and how it changes across different timescales. I use a four-element hydrophone array in central California to present the first published full-season acoustic monitoring and tracking of migrating gray whales. I describe the characteristics of calls produced by migrating gray whales and analyze how these characteristics change due to propagation. I show that gray whale behavior changes on diel and seasonal timescales. Notably, gray whales increase their vocalizations at night but their mean swimming behavior does not change, contrary to previous assumptions used in population size estimates. Over seasonal timescales, vocalizing gray whale swimming behavior aligns with previous observations. I explore how passive acoustic and infrared camera monitoring can help quantify whales by calculating cue rates or call and blow rates for migrating gray whales. Acoustic calling rates indicate that the gray whale population size is greater than estimated using visual sightings alone and that calling rate increases over the southbound migration. Infrared camera blow rates are less affected by whale behavior and are useful for daytime and nighttime monitoring, but are limited by visibility and distance. To understand gray whale behavior over seven migration seasons, I use visual daily counts at two sites and single-hydrophone call detections which indicate that migratory behavior seems to be driven more by intrinsic than the tested environmental factors. I find that the proportion of the population using a coastal route through the Southern California Bight, especially past Los Angeles, increased over these years. Understanding the behavior of migrating gray whales will help improve abundance estimates and determine how these whales may be impacted by nearshore anthropogenic activities and climate change.

Book Synopsis Social Strategies of Carnivorous Mammalian Predators by : Mridula Srinivasan
Download or read book Social Strategies of Carnivorous Mammalian Predators written by Mridula Srinivasan and published by Springer Nature. This book was released on 2023-09-18 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book offers a comparative look at the social strategies of five carnivorous social predators (four terrestrial and one marine) that make them successful hunting units. The focus is on mammalian predators hunting (largely) mammalian prey. Each chapter (with separate authors) devoted to a particular species, explores the versatile hunting techniques and social dynamics of these top predators as they attempt to survive, defend, and reproduce in challenging habitats. Each chapter also delves into how the social fabric and ecology of each species influence their ability to deal with natural and man-made threats and shifting baselines.
