They’ll continue to collect data and samples in a race against deteriorating Arctic sea ice conditions as the onset of summer causes the ice to thin and break up. Even [...]]]> http://blogs.ei.columbia.edu/2013/05/29/a-tale-of-ice-algae-and-the-arctic/feed/ 0 http://blogs.ei.columbia.edu/2013/05/23/ctene-sensations-of-the-arctic-ocean/ http://blogs.ei.columbia.edu/2013/05/23/ctene-sensations-of-the-arctic-ocean/#comments Thu, 23 May 2013 05:40:49 +0000 Rebecca Fowler http://blogs.ei.columbia.edu/?p=36929 One of the goals of Andy Juhl’s and Craig Aumack’s Arctic research is to determine the role of ice algae as a source of nutrition for food webs existing in the water column and at the bottom of the Arctic ocean. During their fieldwork these Lamont-Doherty Earth Observatory scientists are deploying a plankton net, a [...]]]> http://blogs.ei.columbia.edu/2013/05/23/ctene-sensations-of-the-arctic-ocean/feed/ 0 http://blogs.ei.columbia.edu/2013/05/20/collecting-core-data-about-arctic-ecosystems/ http://blogs.ei.columbia.edu/2013/05/20/collecting-core-data-about-arctic-ecosystems/#comments Mon, 20 May 2013 17:53:40 +0000 Rebecca Fowler http://blogs.ei.columbia.edu/?p=36868 Our team spent most of Friday on the Arctic sea ice, drilling and sampling ice cores at our main field site. For each core collected, Lamont-Doherty Earth Observatory scientists Andy Juhl and Craig Aumack take a number of different physical, chemical and biological measurements that characterize the ice and the organisms living inside it.

In the following video, you can clearly see the algae living in the bottom of the ice due to their pigments, which they use to harvest light. These organisms are not frozen into the ice; [...]]]> http://blogs.ei.columbia.edu/2013/05/19/what-lies-beneath-arctic-ice/feed/ 1 http://blogs.ei.columbia.edu/2012/03/21/experience-ecosystems-of-the-dominican-republic/ http://blogs.ei.columbia.edu/2012/03/21/experience-ecosystems-of-the-dominican-republic/#comments Wed, 21 Mar 2012 16:48:19 +0000 Brian Kateman http://blogs.ei.columbia.edu/?p=24267 SEE-U Dominican Republic provides students with many enriching opportunities to engage in fieldwork and study biodiversity and ecosystems in their natural environments.]]> http://blogs.ei.columbia.edu/2012/03/21/experience-ecosystems-of-the-dominican-republic/feed/ 1 http://blogs.ei.columbia.edu/2012/03/13/study-rainforest-ecology-in-puerto-rico-with-see-u/ http://blogs.ei.columbia.edu/2012/03/13/study-rainforest-ecology-in-puerto-rico-with-see-u/#comments Tue, 13 Mar 2012 18:33:24 +0000 Brian Kateman http://blogs.ei.columbia.edu/?p=23881 The SEE-U Puerto Rico course provides students with a total immersion experience into the ecology and dynamics of a fragile and threatened environmental system. ]]> http://blogs.ei.columbia.edu/2012/03/13/study-rainforest-ecology-in-puerto-rico-with-see-u/feed/ 0 http://blogs.ei.columbia.edu/2011/11/07/two-wren-brains-are-better-than-one/ http://blogs.ei.columbia.edu/2011/11/07/two-wren-brains-are-better-than-one/#comments Mon, 07 Nov 2011 19:34:08 +0000 Brian Kateman http://blogs.ei.columbia.edu/?p=19790 When researchers observed activity in the brains of plain-tailed wrens while singing, they discovered something striking: In both sexes, the neurons reacted more strongly to the duet song than individual contributions — they are seemingly wired to enhance cooperation.]]> http://blogs.ei.columbia.edu/2011/11/07/two-wren-brains-are-better-than-one/feed/ 0 http://blogs.ei.columbia.edu/2011/10/27/white-nose-syndrome-is-driving-conservation-batty/ http://blogs.ei.columbia.edu/2011/10/27/white-nose-syndrome-is-driving-conservation-batty/#comments Thu, 27 Oct 2011 19:36:51 +0000 Brian Kateman http://blogs.ei.columbia.edu/?p=19556 Scientists report in a recently published article in Nature that the fungus Geomyces destructans found on bats afflicted with White Nose Syndrome is the primary cause of the disease. However, amidst all the muck of doom and gloom, researchers report in the July issue of the Journal of Wildlife Diseases that affected bats can be nursed back to health with constant medical attention, food, warmth, and water. With no signs of the infection slowing and more than one million bats succumbing to white nose syndrome in the past five years, the conservation community should be on high alert. ]]> http://blogs.ei.columbia.edu/2011/10/27/white-nose-syndrome-is-driving-conservation-batty/feed/ 0 http://blogs.ei.columbia.edu/2011/10/21/executive-courses-in-sustainable-coastal-economies-urban-resilience-and-diversity-and-conservation/ http://blogs.ei.columbia.edu/2011/10/21/executive-courses-in-sustainable-coastal-economies-urban-resilience-and-diversity-and-conservation/#comments Fri, 21 Oct 2011 15:17:18 +0000 Brian Kateman http://blogs.ei.columbia.edu/?p=19308 The Center for Environmental Research and Conservation at Columbia University provides professionals with the knowledge and tools to be effective environmental leaders and decision makers in the 21st century.

And, as more and more people move into densely populated cities, using massive amounts of water, energy, and other resources, the need to combine these disciplines to consider the resilience of urban ecosystems and cities is of paramount importance.]]> http://blogs.ei.columbia.edu/2011/10/12/ecological-and-urban-resilience/feed/ 0
