An analysis of eight categories of goods and services associated with native and restored lands in the lower 48 states finds that restored lands offer 31 percent to 93 percent of native land benefits within a decade of restoration, depending on the biome and the goods and services of interest. The results indicate conservation should be the first priority in planning, but that restoration can have substantial value across broad regions.
Synergies between Agricultural Intensification and Climate Change Could Create Surprising Vulnerabilities for Crops.
Brenda B. Lin, Ivette Perfecto, and John Vandermeer.
The intensification of coffee production that has occurred in recent decades has made that crop--and the millions of people who depend on income from it--more vulnerable to predicted temperature increases and changes in precipitation patterns. Sustainable farming that employs shade trees may improve crops' resistance to temperature and precipitation extremes, according to the article. The authors write that their conclusions could apply to other economically important crops, including cocoa and tea. Note: this article is the subject of a separate BioScience press release dated 9/25/08 entitled "Shade Trees Can Protect Coffee Crops."
The Cambrian Explosion: How Do We Use the Evidence?
Jeffrey S. Levinton.
This article, derived from a talk given to educators, summarizes the state of play in the long-running debate about the apparently very rapid radiation of animal forms around 530 million years ago. Molecular and fossil evidence do not agree precisely about the sequence of events, but indications now are that the "explosion" may have been less sudden than was once thought.
