Image from: BBC News, USFWS/S. Agius </div> <p>Scientists in Maine have converted two Cold War bunkers at Loring Air Force Base into winter havens for bats in an effort to protect the animals from the fungus that causes white nose syndrome. What is nice about using a man-made space is that they can actually clean up the area as opposed to trying to kill the fungus in a cave where multiple species of fungi may be affected, thereby disrupting the micro-ecosystem. The winter survival rate is not very high so far, only 9 out of 30 of the animals survived the stress of capture, transport, and captivity. The researchers have added roosts and closed captioning televisions to the bunkers to help study the animals. I hope their efforts at creating man-made safe havens for these bats works as this fungus has killed up to 6.7 million bats to date, and is continuing to spread.</p> <p><strong>For more information on these bunkers, visit <a href="http://www.bbc.co.uk/news/science-environment-22354517">BBC News</a>.</strong></p> <p><strong>For prior posts on white nose syndrome and bats:</strong></p> <p><a href="http://scienceblogs.com/lifelines/2011/01/05/north-american-bats-face-possi/">North American Bats Face Possible Endangerment</a></p> <p><a href="http://scienceblogs.com/lifelines/2011/06/16/white-nose-syndrome-revisite/">White Nose Syndrome - Revisited</a></p> <p><a href="http://scienceblogs.com/lifelines/2011/09/09/evaporative-water-loss-and-whi/">White Nose Syndrome and Evaporative Water Loss</a></p> <p><a href="http://scienceblogs.com/lifelines/2011/10/04/ask-the-experts-does-ketosis-o/">Does Ketosis Occur During Hibernation?</a></p> <p> </p> <p> </p> </div> <span><a title="View user profile." href="/author/dr-dolittle" lang="" about="/author/dr-dolittle" typeof="schema:Person" property="schema:name" datatype="">dr. dolittle</a></span> <span>Thu, 05/09/2013 - 12:15</span> <div class="field field--name-field-blog-tags field--type-entity-reference field--label-inline"> <div class="field--label">Tags</div> <div class="field--items"> <div class="field--item"><a href="/tag/life-science-0" hreflang="en">Life Science</a></div> <div class="field--item"><a href="/tag/bat" hreflang="en">bat</a></div> <div class="field--item"><a href="/tag/bunker" hreflang="en">bunker</a></div> <div class="field--item"><a href="/tag/cold-war" hreflang="en">cold war</a></div> <div class="field--item"><a href="/tag/hibernate" hreflang="en">hibernate</a></div> <div class="field--item"><a href="/tag/roost" hreflang="en">roost</a></div> <div class="field--item"><a href="/tag/white-nose-fungus" hreflang="en">white nose fungus</a></div> </div> </div> <div class="field field--name-field-blog-categories field--type-entity-reference field--label-inline"> <div class="field--label">Categories</div> <div class="field--items"> <div class="field--item"><a href="/channel/life-sciences" hreflang="en">Life Sciences</a></div> </div> </div> <section> <article data-comment-user-id="0" id="comment-2509056" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1368126323"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Bats are famous for their sensitive hearing - so why do they need closed-caption tv?</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2509056&amp;1=default&amp;2=en&amp;3=" token="kje1htyJDqRUMdYFVVRl5QmeAVwnv50nThffZFLGJCk"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Pierce R.
