Wildfire communication and climate risk mitigation

Publications Posted on: September 27, 2017
Throughout the late 19th century and most of the 20th century, risks associated with wildfire were addressed by suppressing fires as quickly as possible. However, by the 1960s, it became clear that fire exclusion policies were having adverse effects on ecological health, as well as contributing to larger and more damaging wildfires over time.

Costs of induced defenses for the invasive plant houndstongue (Cynoglossum officinale L.) and the potential importance for weed biocontrol

Publications Posted on: September 28, 2016
Inducible plant defenses - those produced in response to herbivore feeding - are thought to have evolved as a cost-saving tactic that allows plants to enact defenses only when needed. The costs of defense can be significant, and loss of plant fitness due to commitment of resources to induced defenses could affect plant populations and play a role in determining the success or failure of weed biocontrol.

Indirect nontarget effects of host-specific biological control agents: Implications for biological control

Publications Posted on: December 14, 2015
Classical biological control of weeds currently operates under the assumption that biological control agents are safe (i.e., low risk) if they do not directly attack nontarget species. However, recent studies indicate that even highly host-specific biological control agents can impact nontarget species through indirect effects. This finding has profound implications for biological control.

Long-term field evaluation of Mecinus janthinus releases against Dalmatian toadflax in Montana (USA)

Publications Posted on: October 03, 2011
The toadflax stem mining weevil, Mecinus janthinus Germar, was first released in the United States in Montana, in 1996. This agent has now become established to varying degrees after subsequent releases made at sites throughout the state. Multiple releases of M. janthinus have presented researchers with a unique opportunity to evaluate the efficacy of this agent in diverse habitats and under a variety of environmental conditions.
