Ecosystem Disturbance

An ecosystem consists of the organisms in an area linked together with their physical and chemical environment. Climate change influences the productivity, distribution, diversity, and seasonality of ecosystems.

VIDEO: Climate Change - Wildlife & Wildlands Last Updated on 2013-07-11 15:42:39 EPA partnered with National Oceanic and Atmospheric Administration, National Aeronautics and Space Administration, National Park Service,U.S. Fish and Wildlife Service, U.S. Forest Service, and Bureau of Land Management to produce a new educational kit, Climate Change, Wildlife, and Wildlands Toolkit for Formal and Informal Educators.The kit contains case studies, activities, and a video based on the highest quality climate science, environmental education and stewardship information, and is designed to educate, inspire, and engage students everywhere to become stewards of our nations wildlife and ecosystems. This video will help people understand the importance of Wildlife and Wildland and how it is affected by recent changes in climate. This 13-minute, high definition, engaging and highly informative video on climate change science and impacts on wildlife and... More »

Predators: influence over habitats Last Updated on 2012-06-14 00:00:00 Study of grasshoppers' diets shows that animals are an important part of organic matter decomposition. While being hunted, prey animal diets may affect how soil releases carbon dioxide. Predators Have Outsized Influence Over Habitats A grasshopper's change in diet to high-energy carbohydrates while being hunted by spiders may affect the way soil releases carbon dioxide into the atmosphere, according to research results published in the journal Science. Grasshoppers like to munch on nitrogen-rich grass because it stimulates their growth and reproduction. But when spiders enter the picture, grasshoppers cope with the stress from fear of predation by shifting to carbohydrate-rich plants, setting in motion dynamic changes to the ecosystem they inhabit, scientists have found. "Under stressful conditions they go to different parts of the 'grocery store'... More »
Climate Change Escape Routes Last Updated on 2011-11-04 00:00:00 One if by Land, Two if by Sea? Climate Change "Escape Routes" Similar movement rates needed for animals and plants on land and in the oceans One if by land, two if by sea? Results of a study published in the Science [Science Magazine, 4 November 2011] show how fast animal and plant populations would need to move to keep up with recent climate change effects in the ocean and on land. The answer: at similar rates. The study was supported by the National Science Foundation (NSF), and performed in part through the National Center for Ecological Analysis and Synthesis. "That average rates of environmental change in the oceans and on land are similar is not such a surprise," says Henry Gholz, program director in NSF's Division of Environmental Biology. "But averages deceive," Gholz says, "and this study shows that rates of change are at times ... More »
Invasive Plant Abundance Last Updated on 2011-02-01 00:00:00 Home and Away: Are Invasive Plant Species Really That Special? Invasive plants are a major environmental problem--but how abundant are they? Invasive plant species are a serious environmental, economic and social problem worldwide. Their abundance can lead to lost native biodiversity and such ecosystem functions as nutrient cycling.   Despite substantial research, however, little is known about why some species dominate new habitats over native plants that technically should have the advantage. A common but rarely tested assumption, say biologists, is that these plants behave in a special way, making them more abundant when introduced into communities versus native plants that are already there. If true, it would mean that biosecurity screening procedures need to address how species will behave once introduced to nonnative communities--very... More »
