Geyser basins with documented negative effects of tourism

Impacts to geyser basins from human activities. At least half of the major geyser basins of the world have been altered by geothermal energy development or tourism. Steingisser 2008.

Yellowstone in a Global Context

n this issue of ellowstone Science, Alethea Steingisser and Andrew Marcus in Human Impacts on Geyser Basins document the global distribution of geysers, the destruc- tion of geysers at the hands of humans, and the tremendous importance of Yellowstone National Park in preserving these rare and ephemeral features. We hope this article will promote further documentation, research, and protection efforts for geyser basins around the world. Documentation of their exis- tence is essential to their protection in the future. I

In her article, Sarah McMenamin describes some unusual salamanders living in the park. The discovery of their trans- lucent color sparked excitement about physiological—rather than genetic—differences caused by environmental factors. Their manifestation is made possible by the environmental diversity Yellowstone provides.

claimed they had been extirpated from the park. As they have since the park’s establishment, jackrabbits continue to persist in the park in a small range characterized by arid, lower eleva- tion sagebrush-grassland habitats. With so many species in the world on the edge of survival, the confirmation of the jackrab- bit’s persistence is welcome.

The Nature Note continues to consider Yellowstone with a broader perspective. Shannon Barber-Meyer, who did her PhD work in Yellowstone on elk calf mortality (see issue 13:3), describes her new experiences as the Tiger Conservation Pro- gram Officer for the World Wildlife Fund. She considers the similarities and differences between Yellowstone and India’s Corbett National Park as well as wolves and tigers.

We hope you enjoy the issue.

We also report on the status and distribution of white- tailed jackrabbits in Yellowstone in response to a study that
