Available in PDF, EPUB and Kindle. Book excerpt: The goal of this study is to provide relevant information on Cook Inlet beluga whales and prey species ecology in the Susitna River and delta with respect to potential changes in the lower river habitat that may result due to construction and operation of the Susitna-Watana Hydroelectric Project. Prey species information for eulachon will be gathered as a part of this study while information for salmon will be coordinated with other fish studies ongoing and proposed for the lower river. The study area (as described in later documents) includes the upper portion of the Cook Inlet, the Susitna River delta, and the river up to river mile 50.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past several years, many investigators interested in the effects of man-made sounds on animals have come to realize that there is much to gain from studying the broader literature on hearing sound and the effects of sound as well as data from the effects on humans. It has also become clear that knowledge of the effects of sound on one group of animals (e.g., birds or frogs) can guide studies on other groups (e.g., marine mammals or fishes) and that a review of all such studies together would be very useful to get a better understanding of the general principles and underlying cochlear and cognitive mechanisms that explain damage, disturbance, and deterrence across taxa. The purpose of this volume, then, is to provide a comprehensive review of the effects of man-made sounds on animals, with the goal of fulfilling two major needs. First, it was thought to be important to bring together data on sound and bioacoustics that have implications across all taxa (including humans) so that such information is generally available to the community of scholars interested in the effects of sound. This is done in Chaps. 2-5. Second, in Chaps. 6-10, the volume brings together what is known about the effects of sound on diverse vertebrate taxa so that investigators with interests in specific groups can learn from the data and experimental approaches from other species. Put another way, having an overview of the similarities and discrepancies among various animal groups and insight into the “how and why” will benefit the overall conceptual understanding, applications in society, and all future research.

Download or read book Sound and Human Impacts on Beluga Whales in Cook Inlet Alaska written by Rachael E. Blevins and published by . This book was released on 2015 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cook Inlet beluga whales (CIBs) are a geographically and genetically isolated population residing in Cook Inlet, Alaska year round. The population declined by approximately 50% between 1994 and 1998 and was listed as endangered under the Endangered Species Act in 2008. The original decline was attributed to overharvest; however, the population has failed to rebound despite the virtual absence of harvest since 1998. This suggests that other factors, such as declining prey availability, increased predation, contaminants, disease, climate change, catastrophic events, habitat loss, unauthorized take, and underwater noise pollution, may be limiting the population's recovery. The goal of this dissertation research was to study the potential impacts of underwater noise on the CIB population. The objective of Chapter 1 was to study CIB acoustic behavior to gain a greater understanding of how CIBs utilize sound. The objective of Chapter 2 was to measure underwater sound levels in Cook Inlet to understand the background noise levels with which CIBs must cope. The objective of Chapter 3 was to document reactions of CIBs to noise disturbance utilizing local ecological knowledge to allow insight into the potential impacts of noise on beluga behavior. The results of Chapter 1 showed that belugas exhibit significant seasonal and spatial variation in calling behavior which suggested differences in habitat usage or differences in the surrounding environment, including background noise levels. The results of Chapter 2 showed that root mean square sound pressure levels exhibited high variation with the highest levels recorded in the 100 Hz frequency band. The seasonal differences in sound levels observed in this study were likely due to greater small vessel traffic and oil and gas development activities in the summer than the winter. In Chapter 3, participants reported observations of CIBs exhibiting avoidance reactions to noise sources including boats, planes, explosions, pile driving, construction, and cars. The results of this chapter showed that noise is perceived to alter beluga behavior and possibly beluga distribution in Cook Inlet. This dissertation research showed that underwater noise has the potential to affect CIBs, however the cost of this impact remains unclear and warrants further study. In light of the lack of support for many of the proposed factors limiting the population and the need for further research for many of these factors, it would be valuable to consider the cumulative effects of these multiple stressors. While their potential impact may be small individually, when combined, these factors may have a synergistic and significant impact on individual whales and, in turn, on the CIB population. Management of cumulative effects may be necessary to ensure the recovery of this endangered population.
