The First Principal Component (FPC) scores derived from the molds in Cluster 7 (Aureobasidium pullulans, Eurotium amstelodami, Scopulariopsis brevicaulis, Stachybotrys chartarum, Mucor racemosus, and Rhizopus stolonifer) plotted by latitude and longitude as an 𝑥, 𝑦 event layer using the software program ArcGIS Desktop 9.3.1 (ESRI Inc., Redlands, CA). The values were classified using a five-category natural break classification. The five categories are indicated by combined grey scale and graduated symbol size, with the smallest size and lightest color representing the category with the smallest values.
