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.
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
On Thursday we lowered a camera into an ice borehole to get a look at the underside of the ice. 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.
SEE-U Dominican Republic provides students with many enriching opportunities to engage in fieldwork and study biodiversity and ecosystems in their natural environments.
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.
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.
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.
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. It is an evening program in which environmental issues are discussed, debated and examined, where participants develop an in-depth understanding of conservation science and practice through case studies and a focus on Environmental Policy, Management and Finance.
Resilience science has been evolving over the past decade, expanding beyond ecology to reflect systems of thinking in fields such as economics and political science. 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.
