The First Principal Component (FPC) scores derived from the molds in Cluster 3 (Aspergillus fumigatus, Paecilomyces variotii, Penicillium brevicompactum, P. corylophilum, and P. variabile) 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.
