Aquatic Records
-
The karst map provides the basic template for analyzing the distribution of cave species. Almost without exception, all caves occur within the karst areas. There were a few records of cave-dwelling species from outside karst areas (mostly springs) but the data was trimmed to fit within the karst areas, with a 1 km buffer to allow for errors in georeferencing). This map displays the aquatic records within karst areas in the Appalachian region.

Percentage of Karst Area within Grid Cell
-
Each cell represents the percent of karst within a 20 x 20 kilometer grid cell, a measure of habitat quantity. This attribute can be used to predict presence/absence of particular ecological groups in caves.

Cave Species Richness Hotspots
-
Caves with the most aquatic and terrestrial species. The number of species is highly dependent on sampling intensity, including the number of sampling trips.

Carbonate/Non-carbonate Contact Linear Sum
-
Cumulative lengths of contacts between karst and non-karst, measuring both patchiness of available habitat and perhaps dispersal corridors if cave passages are differentially developed along these contacts. This information can be used to predict presence/absence of particular ecological groups in caves.
