From 1991 to 1996, Jeffrey pine beetles (Dendroctonus jeffreyi Hopkins) (JPB) caused tree mortality throughout the Lake Tahoe Basin during a severe drought. Census data were collected annually on 10,721 trees to assess patterns of JPB-caused mortality. This represents the most extensive tree-level, spatiotemporal dataset collected to-date documenting bark… (More)
PROJECT OBJECTIVES: To monitor changes in tree population health, fuel loadings, and fire hazard on a high elevation landscape using an extensive gridded plot network JUSTIFICATION: a. Linkage: Monitoring from FHM (aerial surveys), FIA, and FHP-ground surveys have indicated increases in mountain pine beetle-caused lodgepole pine mortality throughout Region… (More)
We compared, under laboratory conditions, the resistance to cutting out of the AO dynamic hip screw and the Pugh sliding nail. The mean load at cut out, adjusted for bone strength, was 70% greater for the Pugh sliding nail. The reasons for this difference are discussed.
