Data from: High genetic diversity in the landscape suggests frequent seedling recruitment by Euphorbia virgata Waldst. & Kit. (leafy spurge) in the northern U.S.A.

Site information and field-collected data from a 1-year 100-site survey of leafy spurge (Euphorbia virgata/esula) populations in the northern U.S. Data include: 1) estimates of leafy spurge density and relative prevalence of ramets versus genets; 2) the abundance and composition of Aphthona species complex biological control agents; 3) presence/absence of two additional biological control agents (Oberea erythrocephala and Hyles euphorbiae).

Intended Use
We conducted a survey of 100 Euphorbia virgata Waldst. & Kit. (leafy spurge) populations across three U.S. states to quantify weed genetic diversity, density, and associated root-feeding biocontrol agent (Aphthona species complex) abundance. Aphthona spp. reduce survivorship and clonal recruitment, and their impacts may indirectly influence the value of seed-based recruitment to weed population increase and persistence. We intended to provide insight into: 1) the frequency of seedling recruitment among populations, which is strongly related to population genetic diversity in clonal plants such as E. virgata; and 2) the degree to which E. virgata density is related to the abundance of Aphthona spp. agents and inferred clonality within local weed populations.
Use Limitations
1. Sites were chosen based on previous history of Aphthona release. Thus, the frequency of Aphthona occurrence does not reflect a probability of randomly detecting Aphthona species in the landscape. Similarly, the composition of the Aphthona species complex at each site will be strongly influenced by introduction history, and does not directly indicate colonization limitations among species. 2. This is a 1-year dataset, so Aphthona abundance should be interpreted as relative rather than absolute differences in insect numbers per site. 3. The timing of sampling was based on the phenology of the Aphthona species complex; thus, other biological control agents with different seasonal patterns are likely under-sampled.
