Are Weevils Picky Eaters? Community Structure and Host Specificity of Neotropical Saproxylic Beetles (Coleoptera: Curculionidae)
… on the Osa Peninsula, Costa Rica. The subfamily Scolytinae was expected to be the most species-rich and abundant. Ambrosia beetles were expected to have more generalist species than other curculionids. Old growth forest was expected to yield more diversity and specialized curculionids, showing …

Forest Mortality in Lake Tahoe Basin from 1985-2010: Influences of Forest Type, Stand Density, Topography and Climate
… is mediated by native bark beetles (Coleoptera: Scolytinae), more proximal exogenous factors such as drought, and endogenous factors such as stand density and environmental setting have also been implicated (Allen et al. 2010). This study utilizes remote sensing imagery from the 1985-2010 Landsat …
