Scaling use of the rust fungus Puccinia punctiformis for biological control of Canada thistle (Cirsium arvense (L.) Scop.): First report on a U.S. statewide effort

This study reports on an 8-year monitoring effort of a biological control program using the rust fungus Puccinia punctiformis to reduce Canada thistle stem densities in Colorado, finding declines linked to environmental factors and inoculum deployment.

Adaptation at the edge: Patterns of local adaptation and genetic variation during a contemporary range expansion

The paper examines how genetic variation and adaptation differ between core and expanding edge populations during a range expansion, finding that core populations are better adapted to local environments than edge populations.

Hybridization and range expansion in tamarisk beetles (Diorhabda spp.) introduced to North America for classical biological control

This study examines the genomic consequences of hybridization and range expansion in tamarisk beetles introduced to North America for biocontrol, finding increased genetic diversity in hybridized populations.
