Where communities already occupy lahar hazard zones or where transient populations move in and out, a lahar warning system can be an option that would allow an at-risk population to safely evacuate prior to lahar arrival, whether or not used in conjunction with engineered protection structures.
For years, no one gave much of a damn about the people of Skid Row or what they did, as the population was safely segregated far away from rich neighborhoods in Santa Monica and Beverly Hills.
As a result, the fishing mortality that a population can safely sustain can be lower than what would be predicted if the elevated mortality among spawners was not accounted for.

Consequently, inferences to larger populations cannot be safely made.
Finally, we will highlight the general challenges that must be overcome and the strategies being developed to generate highly-purified hESC-derived cell populations that can safely be used for clinical applications.
