Exploratory visualization of HFRS niche in two-dimensional environmental space. Gray indicates available environmental conditions, and black the modeled ecological niche of hantavirus: (a) annual precipitation and annual temperature; (b) precipitation seasonality and temperature seasonality; (c) compound topographic index and elevation; (d) land use. Solid line depicts variation in mean monthly NDVI values of (e) predicted absent, and (f) predicted present.
