A Bird’s Eye View of Changing Landscapes: Using Google Earth to Explore Changing Landscapes
Students use Google Earth and satellite imagery from the United Nations Environmental Programme’s Atlas of our Changing Environment to discover ways in which landscapes change over time due to human actions and natural forces. By analyzing patterns in current and historical satellite images from locations around the world, students explore various types of landscape change and predict potentia...

Climate, Weather and Anthropogenic Activity
This module presents a science-based story to demonstrate how climate determines the global, long-term, large-scale distribution of living organisms; whereas, weather determines the local, short-term, small-scale ecology of living organisms. Life thrives within specific, often narrow ranges of temperature and precipitation – two main players in climate and weather. Using a systems-based approach,...

Landscape Ecology of Large, Infrequent Fires in Yellowstone Park
This Issue focuses on a research article by Turner et al. (2003) that was published in Frontiers in Ecology and the Environment. The article discusses the ecological causes and effects of intense, infrequent fires such as the large fire that occurred during 1988 in Yellowstone National Park. Turner et al. synthesize 15 years of research on vegetation and ecological processes at Yellowstone and...
