John Boatwright, Luke Blair, Rufus Catchings, Mark Goldman, Fabio Perosi, Clare Steedman
2004, Open-File Report 2004-1282
Campbell (1983) demonstrated that site amplification correlates with depths to the 1.0, 1.5, and 2.5 km/s S-wave velocity horizons. To estimate these depths for the Bay Area stations in the PEER/NGA database, we compare the depths to the 3.2 and 4.4 km/s P-wave velocities in the Brocher and others (1997)...
The effects of mixotrophy on the stability and dynamics of a simple planktonic food web
Christian Jost, Cathryn A. Lawrence, Francesca Campolongo, van de Bund Wouter, Sheryl Hill, Donald L. DeAngelis
2004, Theoretical Population Biology (66) 37-51
Recognition of the microbial loop as an important part of aquatic ecosystems disrupted the notion of simple linear food chains. However, current research suggests that even the microbial loop paradigm is a gross simplification of microbial interactions due to the presence of mixotrophs—organisms that both photosynthesize and graze. We present...
