Natural hazards on alluvial fans: the debris flow and flash flood disaster of December 1999, Vargas state, Venezuela Natural hazards on alluvial fans: the debris flow and flash flood disaster of December 1999, Vargas state, Venezuela
Large populations live on or near alluvial fans in locations such as Los Angeles, California, Salt Lake City, Utah, Denver, Colorado, and lesser known areas such as Sarno, Italy, and Vargas, Venezuela. Debris flows and flash floods occur episodically in these alluvial fan environments, and place many communities at high risk during intense and prolonged rainfall. In December 1999...

The U.S. National Amphibian Research and Monitoring Initiative and the role of protected areas The U.S. National Amphibian Research and Monitoring Initiative and the role of protected areas
In response to concerns about the worldwide status of amphibians (Alford and Richards 1999; Bury 1999; Daszak et al. 1999; Houlahan et al. 2000), Congress in Fiscal Year 2000 provided initial support to agencies of the U.S. Department of the Interior for research and monitoring of amphibians. Most funds came to the U.S. Geological Survey (USGS), but additional funds for the U.S. Fish and...

Population dynamics and the ecological stability of obligate pollination mutualisms Population dynamics and the ecological stability of obligate pollination mutualisms
Mutualistic interactions almost always produce both costs and benefits for each of the interacting species. It is the difference between gross benefits and costs that determines the net benefit and the per-capita effect on each of the interacting populations. For example, the net benefit of obligate pollinators, such as yucca and senita moths, to plants is determined by the difference...
