Distribution of examined mammalian species in Ecuador across ecological regions.
Panel A represents the sampling magnitude of mammal specimens across the Amazon rainforest, Andean highlands, and Coast lowlands. Panel B illustrates the frequency of Histoplasma capsulatum detected in mammalian tissues within these regions. Ecuador, located on the equatorial line northwest of South America, provides this study’s unique geographic and ecological context.

Fig 2.
Potential distribution of Histoplasma capsulatum based on environmental clustering.
Environmental suitability was modeled using one-class support vector machine (OC-SVM) hypervolumes to identify clusters in environmental space (A), represented by principal components (PC1, PC2, and PC3), and later projected onto the geographic landscape of Ecuador (B). The geographic projection highlights suitability categories (low, medium, and high) across regions, with high suitability areas primarily concentrated in northern Ecuador, spanning the Coast and Andean regions. Pink dots indicate locations where H. capsulatum was detected. Figure was developed using the packages alphahull and ggplot2 in R programming language and the official shapefile of Ecuador developed by the Technical Secretary of the National Committee on Internal Limits (CONALI in Spanish), available at: https://www.gob.ec/conali”.
