Effects of biological control agents and exotic plant invasion on deer mouse populations

Publications Posted on: April 21, 2015
Exotic insects are commonly introduced as biological control agents to reduce densities of invasive exotic plants. Although current biocontrol programs for weeds take precautions to minimize ecological risks, little attention is paid to the potential nontarget effects of introduced food subsidies on native consumers. Previous research demonstrated that two gall flies (Urophora affinis and U.

Mitigating exotic impacts: restoring native deer mouse populations elevated by an exotic food subsidy

Publications Posted on: September 02, 2008
The threat posed by exotic organisms to native systems has led to extensive research on exotic invaders, yet management of invasives has progressed relatively slowly. This is partly due to poor understanding of how exotic species management influences native organisms.

Weed biocontrol insects reduce native plant recruitment through second-order apparent competition

Small-mammal seed predation is an important force structuring native-plant communities that may also influence exotic-plant invasions. In the intermountain West, deer mice (Peromyscus maniculatus) are prominent predators of native-plant seeds, but they avoid consuming seeds of certain widespread invasives like spotted knapweed (Centaurea maculosa). These mice also consume the biological-control insects Urophora spp.
