Host Range and Impact of , the First Potential Biological Control Agent for in North America and Australia.

We evaluated the potential of the European root-feeding moth as a biological control agent for the invasive weed (oxeye daisy) in North America and Australia. The taxonomic proximity of the ornamental Shasta daisy () to and its popularity in North America made finding sufficiently host-specific biological control agents a challenge. No-choice tests conducted with 74 non-target species revealed partial or complete larval development on 11 species.

Projecting future expansion of invasive species: comparing and improving methodologies for species distribution modeling.

Modeling the distributions of species, especially of invasive species in non-native ranges, involves multiple challenges. Here, we developed some novel approaches to species distribution modeling aimed at reducing the influences of such challenges and improving the realism of projections. We estimated species-environment relationships for Parthenium hysterophorus L.
