This video describes how scientists are studying freshwater wetlands on the North Island of New Zealand and how nutrients from pasture runoff may alter the vegetation and peat formation in these important ecosystems. Much of what is known about wetlands comes from research conducted in the Northern Hemisphere.

"The Heat is On: Desert Tortoises and Survival" is a thirty minute television program exploring the world of the Mojave Desert Tortoise. It highlights the USGS research program on the Desert Tortoise and the role of that research in managing desert environments to allow the species to recover and escape the threat of extinction.
