Download or read book Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-05-04 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine mammals face a large array of stressors, including loss of habitat, chemical and noise pollution, and bycatch in fishing, which alone kills hundreds of thousands of marine mammals per year globally. To discern the factors contributing to population trends, scientists must consider the full complement of threats faced by marine mammals. Once populations or ecosystems are found to be at risk of adverse impacts, it is critical to decide which combination of stressors to reduce to bring the population or ecosystem into a more favorable state. Assessing all stressors facing a marine mammal population also provides the environmental context for evaluating whether an additional activity could threaten it. Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals builds upon previous reports to assess current methodologies used for evaluating cumulative effects and identify new approaches that could improve these assessments. This review focuses on ways to quantify exposure-related changes in the behavior, health, or body condition of individual marine mammals and makes recommendations for future research initiatives.

This book was released on 2016 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The National Marine Fisheries Service (NMFS) is responsible for gathering the information needed to support its stock assessments of marine mammals. The distribution and abundance of each stock is the core of those assessments. Data to support stock assessments are traditionally gathered by conducting visual observations during shipboard and/or aerial surveys. Increasingly, however, the agency is having difficulty provide abundance estimates and other data needed for marine mammal stock assessments. These challenges have spurred NMFS to increase its investment in alternative monitoring methods that may fill some critical data gaps more effectively and efficiently than large-scale ship and aerial surveys alone"--Introduction

This book was released on 1972 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper reports the second phase of an effort to use instrumented marine mammals to measure selected environmental parameters and to relay data on these parameters to tracking aircraft and ultimately to orbiting satellites. A Pacific common dolphin, Delphinus delphis, was fitted with an instrument package and tracked from shipboard and from specially equipped Navy S-2D aircraft. The preferability of smaller odontocetes over larger mystictes as environmental survey platforms was demonstrated. Data collected compared favorably with data from previous radio tracks and with on-site measurements using conventional sampling techniques. Maximum transmitter range and optimum tracking and data collection altitudes were demonstrated for present systems. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Interest in marine mammals has increased dramatically in the last few decades, as evidenced by the number of books, scientific papers, and conferences devoted to these animals. Nowadays, a conference on marine mammals can attract between one and two thousand scientists from around the world. This upsurge of interest has resulted in a body of knowledge which, in many cases, has identified major conservation problems facing particular species. At the same time, this knowledge and the associated activities of environmental organisations have served to introduce marine mammals to a receptive public, to the extent that they are now perceived by many as the living icons of biodiversity conservation. Much of the impetus for the current interest in marine mammal conservation comes from "Save the Whale" campaigns started in the 1960s by environmental groups around the world, in response to declining whale populations after over-exploitation by humans. This public pressure led to an international moratorium on whaling recommended in 1972 by the United Nations Conference on the Human Environment in Stockholm, Sweden, and eventually adopted by the International Whaling Commission ten years later. This moratorium largely holds sway to this day, and further protective measures have included the delimitation of extensive areas of the Indian Ocean (1979) and Southern Ocean (1994) as whale sanctuaries.
