Is there a basis for preferring characteristic earthquakes over a Gutenberg–Richter distribution in probabilistic earthquake forecasting?
Thomas E. Parsons, Eric L. Geist
2009, Bulletin of the Seismological Society of America (99) 2012-2019
The idea that faults rupture in repeated, characteristic earthquakes is central to most probabilistic earthquake forecasts. The concept is elegant in its simplicity, and if the same event has repeated itself multiple times in the past, we might anticipate the next. In practice however, assembling a fault-segmented characteristic earthquake rupture...

Parasites reduce food web robustness because they are sensitive to secondary extinction as illustrated by an invasive estuarine snail
Kevin D. Lafferty, Armand M. Kuris
2009, Philosophical Transactions of the Royal Society B: Biological Sciences (364) 1659-1663
A robust food web is one in which few secondary extinctions occur after removing species. We investigated how parasites affected the robustness of the Carpinteria Salt Marsh food web by conducting random species removals and a hypothetical, but plausible, species invasion. Parasites were much more likely than free-living species to...
