They found that levels of the whales&rsquo; stress levels fell when ship traffic was reduced as a security measure and ocean noise to fall by half.</p> <p> <br /> &quot;What this study has shown is that they are having a measurable physiological stress response to the noise in their environment,&rdquo; Rolland <a href="http://www.livescience.com/18367-ship-noise-stresses-whales.html">told LiveScience.</a></p> <p> <br /> The researchers believe that these high stress levels may cause behavioral changes in the whales, as well as impacting their immune and reproductive systems, <a href="http://www.livescience.com/18367-ship-noise-stresses-whales.html">LiveScience says.</a></p> <p> <a href="http://www.telegraph.co.uk/science/science-news/9068202/Shipping-noise-causes-major-stress-in-whales.html"><br /> <em>The Telegraph </em>explains</a> that ships&rsquo; propellers emit sound in the same frequency range that some whales use for communicating. It cites previous studies which have shown the whales change their calling patterns in noisy places.</p> <p> <br /> &quot;We knew whales changed the frequency of their calls to adapt to the ship noise, but these work shows it is not merely an annoyance - it is having a physical effect,&quot; the newspaper quotes Rolland as saying.</p> <p><a href="http://www.globalpost.com/dispatches/globalpost-blogs/weird-wide-web/scientists-find-link-between-whale-stress-and-ocean-noise" target="_blank">read more</a></p> 9/11 Canada shipping noise United States whales Canada United States Weird Wide Web Thu, 09 Feb 2012 01:22:00 +0000 Hélène Hofman 5691015 at http://www.globalpost.com Paul Watson, Sea Shepherd founder, skips bail in Germany http://www.globalpost.com/dispatch/news/regions/europe/germany/120726/paul-watson-sea-shepherd-founder-skips-bail Watson has previously dismissed the charges against him as an "inconvenience," and said his ships would soon "stop the illegal activities of whale-hunting fleets once again."<p><a href="http://www.globalpost.com/dispatch/news/regions/europe/germany/120726/paul-watson-sea-shepherd-founder-skips-bail" target="_blank">read more</a></p> whales Wildlife News Germany Costa Rica Japan Thu, 26 Jul 2012 14:46:00 +0000 Jessica Phelan 5713513 at http://www.globalpost.com Japanese whaling ships have left the Southern Ocean, says Sea Shepherd http://www.globalpost.com/dispatch/news/science/wildlife-news/130302/japanese-whaling-ships-have-left-the-southern-ocean-says- Anti-whaling group Sea Shepherd claims that Japanese whaling vessels have left the Southern Ocean whale sanctuary and are heading north, likely towards Indonesia and than to home.<p><a href="http://www.globalpost.com/dispatch/news/science/wildlife-news/130302/japanese-whaling-ships-have-left-the-southern-ocean-says-" target="_blank">read more</a></p> whales Green Want to Know Asia-Pacific Wildlife News Japan Science Sat, 02 Mar 2013 07:01:00 +0000 Faine Greenwood 5771563 at http://www.globalpost.com
