Book Description
Shipping is increasing in Arctic regions, exposing previously naïve marine mammal populations to underwater shipping-related noise. I assessed the impact of shipping on the acoustic habitat of narwhal (Monodon monoceros) and other local marine fauna. Broadband sound pressure levels (SPL; 10 Hz-25 kHz) under auditory weighing functions were compared between times of ship presence and absence using noise levels from passive acoustic recorders. Effects of ship presence and noise on narwhal behaviour were also analyzed. Broadband SPL were significantly reduced under narwhal hearing scenarios relative to unweighted levels. Narwhal perceived shipping noise at low levels and did not perceive increases until ships were within 5 km. No significant changes in narwhal behaviour were observed when only ships were present. Behavioural changes caused by other stressors were observed. Ship presence frequently occurred along with other stressors, limiting observations of behavior in the presence of ships. Continued monitoring is recommended.
A Little Less Arctic

Pages : 313
Book Description
In Arctic Canada, Hudson Bay is a site of great exploration history, aboriginal culture, and a vast marine wilderness supporting large populations of marine mammals and birds. These include some of the most iconic Arctic animals like beluga, narwhal, bowhead whales, and polar bears. Due to the challenges of conducting field research in this region, some of the mysteries of where these animals move, and how they are able to survive in such seemingly inhospitable, ice-choked habitats are just now being unlocked. For example, are polar bears being replaced by killer whales? This new information could not be more salient, as the Hudson Bay Region is undergoing rapid environmental change due to global warming, as well as increased pressures from industrial development interests. A Little Less Arctic brings together some of the world’s leading Arctic scientists to present the current state of knowledge on the physical and biological characteristics of Hudson Bay.
Addis Ababa Principles and Guidelines for the Sustainable Use of Biodiversity
Author: Publisher:
ISBN: 9789292250034
Category : Biodiversity
Languages : en
Pages : 21
Book Description
The Addis Ababa principles and guidelines for the sustainable use of biodiversity provide a framework for assisting governments, indigenous and local communities, resource managers, the private sector and other stakeholders, about how to ensure that their uses of biological diversity will not lead to its long-term decline. The practical principles in most instances apply to both consumptive and non-consumptive uses of biodiversity components. They take into account requirements related to policies, laws, and regulations; management of biological diversity; socio-economic conditions; and information, research, and education.
