Crayfish Species Distribution by 1km Grid: Distribution of crayfish species by 1 kilometer grid throughout the Appalachian LCC region.

Aseillid Isopod Species Distribution by 1km Grid: Distribution of asellid isopods by 1 kilometer grid throughout the Appalachian LCC region.

Amphipod Species Distribution by 1 km Grid: Distribution of the amphipod species group by 1 kilometer grids throughout the Appalachian LCC region.

Human Population Change by County from 2001-2010: Human population change at the county level from 2001- 2010.

Probability of Presence - Aquatic Species: As a first step toward a predictive model of hotspots of species richness based on the predictive variables outlined above, the probabilities of each group within each grid cell were summed (excluding fish which do not occur at all in the Central Appalachians, making predictions impossible). The probabilities were summed to indicate locations that have one or more of the species groupings. Higher values indicate that more species are likely to be found. The map of predicted aquatic species richness has broader swaths of species richness, especially in the Interior Low Plateau.

Probability of Presence - Terrestrial Species: As a first step toward a predictive model of hotspots of species richness based on the predictive variables outlined above, the probabilities of each group within each grid cell were summed (excluding fish which do not occur at all in the Central Appalachians, making predictions impossible). The probabilities were summed to indicate locations that have one or more of the species groupings. Higher values indicate that more species are likely to be found. For the five terrestrial groups, the major hotspot is in northeast Alabama and south central Tennessee, mimicking the observed data. However, there are also hotspots in southwest Virginia, and central West Virginia that do not appear on the map of species richness.

Mean Annual Temperature: Mean annual temperature at 1 kilometer resolution throughout the Appalachian LCC region.

Precipitation Seasonality: Precipitation seasonality using coefficient of variation at 1 kilometer resolution throughout the Appalachian LCC region.

Mean Annual Precipitation: Mean annual precipitation (mm/year) at a 1 kilometer resolution throughout the Appalachian LCC region.

Forest Biomass: Forest biomass at the 1 kilometer scale throughout the Appalachian LCC region.

Stream Baseflow Index: Average annual stream baseflow index at 1 kilometer resolution throughout the Appalachian LCC region.

Terrestrial Species Richness by County: Distribution of terrestrial species richness at the county scale throughout the Appalachian LCC region.

Terrestrial Species Richness: Distribution of terrestrial species richness in 20 kilometer grids throughout the Appalachian LCC region.

Aquatic Species Richness by County: Distribution of aquatic species at the county scale throughout the Appalachian LCC region.

Aquatic Species Richness: Distribution of aquatic species richness by 20 kilometers grids throughout the Appalachian LCC region. At this scale, the hotspots of aquatic species richness are in southern Indiana (the Mitchell Plain) and central Kentucky (Mammoth Cave).

NatureServe Regions and Karst: Three basic regions are identified by NatureServe; Interior Low Plateaus,Central Appalachians, and Cumberland Southern Blue Ridge. These ares are displayed along with karst resources within the Appalachian LCC region.

Single County Endemic Species: Number of endemic species at the county level throughout the Appalachian LCC region.

Single Grid Cell Endemics: Many aquatic and terrestrial species are geographically rare, often found in a single cave. This map dis[;ays the geographic distribution of endemics scattered throughout the Appalachian LCC region.

Stygobiont and Troglobiont Endemics by Cave: Total number of stygobiont and troglobiont endemic species within a cave.
