Glaciers and Icebergs at Cape York edit 4.jpg Management and Conservation of Wildlife in a Changing Arctic Environment Last Updated on 2014-07-07 18:45:12 This is Chapter 11 of the Arctic Climate Impact Assessment Lead Author: David R. Klein; Contributing Authors: Leonid M. Baskin, Lyudmila S. Bogoslovskaya, Kjell Danell, Anne Gunn, David B. Irons, Gary P. Kofinas, Kit M. Kovacs, Margarita Magomedova, Rosa H. Meehan, Don E. Russell, Patrick Valkenburg Climate changes in the Arctic in the past have had major influences on the ebb and flow in availability of wildlife to indigenous peoples and thus have influenced their distribution and the development of their cultures.Trade in animal parts, especially skins and ivory of marine mammals, and trapping and sale of fur-bearing animals go far back in time. Responsibility for management and conservation of wildlife in the Arctic falls heavily on the residents of the Arctic, but also on the global community that shares in the use of arctic resources. A sense of global stewardship toward the... More »
10 01 02aaa.jpg Pfiesteria (Ecological Risk Assessment) Last Updated on 2014-06-15 18:34:27 This article was researched and written by a student at Mount Holyoke College participating in the Encyclopedia of Earth's (EoE) Student Science Communication Project. The project encourages students in undergraduate and graduate programs to write about timely scientific issues under close faculty guidance. All articles have been reviewed by internal EoE editors, and by independent experts on each topic. Algal blooms were once considered solely a natural phenomenon in coastal ecosystems. But, in recent years, the frequency and severity of algal blooms have increased dramatically, due primarily to anthropogenic activities that create agricultural and sewage runoff resulting in nutrient loading in coastal ecosystems. This runoff and nutrient loading stimulates the growth of many algal species. Algal blooms that have harmful implications to the surrounding environment and to human... More »
Cells3-smH1287009539.jpg Complex Systems (Ecological Risk Assessment) Last Updated on 2013-10-24 15:13:11 As Science has begun to ask where the enduring features of nature come from and how they work, the answer seems to be “complex systems”. Every kind of thing and event seems to require them. As the science has advanced, and as the modern problems of economies and environmental conflicts emerge, a new kind of science is emerging that requires being very openly exploratory, using all the tools and combining all the related perspectives of others, to develop complex knowledge systems matching the variety of the complex system problems they respond to. Systems are storms or “like storms” in many respects, complex distributed phenomena that may be either unexpectedly eventful or highly predictable. There’s still a rather wide range of opinion within science as to what complex systems are, even whether they are made of information or... More »
ContentImg.jpg Toxicity testing- new dimensions Last Updated on 2013-09-13 23:25:02 This article, written by Charles W. Schmidt[1], appeared first in Environmental Health Perspectives—the peer-reviewed, open access journal of the National Institute of Environmental Health Sciences. The article is a verbatim version of the original and is not available for edits or additions by Encyclopedia of Earth editors or authors. Companion articles on the same topic that are editable may exist within the Encyclopedia of Earth. On the ground floor of the National Institutes of Health Chemical Genomics Center (NCGC) in Rockville, Maryland, a $10-million automated laboratory spends all day and night screening chemicals at speeds no team of human researchers could ever match. In a week, depending on the nature of the assay, it can yield up to 2.2 million molecular data points derived from thousands of chemicals tested at 15 concentrations each. Is this the new face...
