Available in PDF, EPUB and Kindle. Book excerpt: This area includes a portion from the Saguenay Fjord to Baie Sainte-Marguerite, the entire upper estuary between Ile-aux-Coudres and the mouth of the Saguenay Fjord, and the southern waters of the lower estuary extending to the east off the coast of Saint-Fabien-sur-Mer. [...] Distribution and use of habitat by the SLE Beluga The distribution range of the SLE Beluga is about 65% of what it was historically, and it is one of the smallest reported for this species. [...] Existing data outside of the summer period, though sparse, suggest that the Beluga abandons the upper estuary in the fall and concentrates in the lower estuary and the northwestern portion of the Gulf. [...] Indices of vocal activity obtained from a continuous listening station off the coast of Cacouna, which covered a large portion of the RCIV area, show the presence of Belugas in that area both during the day and at night, for the whole period of the study, from June to October 2014 (Roy and Simard 2015). [...] Work done by Auger and Powles (1980); Bio-Conseil (1982) and Fortier and Gagné (1990) documenting the emergence of large quantities of herring larvae in the upper estuary highlight the importance of this species in the region in the spring.

Available in PDF, EPUB and Kindle. Book excerpt: This document reviews the current state of knowledge about St. Lawrence belugas, recommends a series of actions for ensuring their survival and proposes an implementation schedule. The goal of the Recovery Plan is to bring population numbers and conditions to a state where natural event and human activities will not threaten the survival of the St. Lawrence beluga whale population. A subsidiary goal is to improve the status from endangered to vulnerable, as defined by COSEWIC.

Download or read book Marine Environmental Assessment of the Estuary and Gulf of St Lawrence written by Louise White and published by Dartmouth, N.S. : Fisheries and Oceans Canada, Toxic Chemicals Program. This book was released on 1997 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This assessment is a summary of the accumulated scientific understanding of the estuary and Gulf of St. Lawrence. It discusses the extent of anthropogenic modifications to this marine environment, points out principal uncertainties that hinder our understanding, and identifies important regional environmental issues. Many assessments attempt to provide easy-to-understand information to a wide, non-specialist audience. Others are directed more specifically to scientists, but include a conclusions section written for non-scientists. This document offers something of a middle approach: it is intended to be understood by a non-specialist audience, albeit one with a general knowledge of contemporary science. At the same time, it gives the professional scientist a broad-scale synthesis of current information.

Available in PDF, EPUB and Kindle. Book excerpt: Scientific documentation on sediment chemistry and the contamination potential of open-water disposal of dredged material are criticallly reviewed and summarized in this report. Analyses, comparisons and recommendations are made on techniques for possible use in dredging projects. The most important limitations of these techniques are described. Recommendations are made for the establishment of priorities for future research on dredging projects, particularly those on the St. Lawrence River.

Available in PDF, EPUB and Kindle. Book excerpt: This report is an evaluation of the sediment quality of the St. Lawrence River. Where possible, trends in changes that may have occurred between 1976 and 1989 have been determined. Seven metals were focused on: cadmium, chromium, copper, mercury, nickel, lead and zinc. Sites at which heavy metals were the highest are identified and, whenever possible, related to toxic inflows from the River's international section, priority industries, tributaries and riverside municipalies.

Download or read book Effects of Anthropogenic Noise on Animals written by Hans Slabbekoorn and published by Springer. This book was released on 2018-08-20 with total page 322 pages. 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.
