Crayfish Species Distribution by 1km Grid by Jessica Rhodes, last updated: Mar 11, 2016 09:48 AM: Distribution of crayfish species by 1 kilometer grid throughout the Appalachian LCC region.

Aseillid Isopod Species Distribution by 1km Grid by Jessica Rhodes, last updated: Mar 11, 2016 09:48 AM: Distribution of asellid isopods by 1 kilometer grid throughout the Appalachian LCC region.

Amphipod Species Distribution by 1 km Grid by Jessica Rhodes, last updated: Mar 11, 2016 09:48 AM: Distribution of the amphipod species group by 1 kilometer grids throughout the Appalachian LCC region.

Protected Lands by Jessica Rhodes, last updated: Mar 11, 2016 09:48 AM: Protected lands within the Appalachian LCC region.

Human Population Change by County from 2001-2010 by Jessica Rhodes, last updated: Mar 11, 2016 09:48 AM: Human population change at the county level from 2001- 2010.

Probability of Presence - Aquatic Species by Jessica Rhodes, last updated: Mar 11, 2016 09:48 AM: 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 by Jessica Rhodes, last updated: Mar 11, 2016 09:48 AM: 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 by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Mean annual temperature at 1 kilometer resolution throughout the Appalachian LCC region.

Precipitation Seasonality by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Precipitation seasonality using coefficient of variation at 1 kilometer resolution throughout the Appalachian LCC region.

Mean Annual Precipitation by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Mean annual precipitation (mm/year) at a 1 kilometer resolution throughout the Appalachian LCC region.

Forest Biomass by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Forest biomass at the 1 kilometer scale throughout the Appalachian LCC region.

Terrestrial Species Richness by County by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Distribution of terrestrial species richness at the county scale throughout the Appalachian LCC region.

Terrestrial Species Richness by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Distribution of terrestrial species richness in 20 kilometer grids throughout the Appalachian LCC region.

NatureServe Regions and Karst by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: 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 by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Number of endemic species at the county level throughout the Appalachian LCC region.

Single Grid Cell Endemics by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: 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 by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Total number of stygobiont and troglobiont endemic species within a cave.

Carbonate/Non-carbonate Contact Linear Sum by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: 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.

Cave Species Richness Hotspots by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Caves with the most aquatic and terrestrial species. The number of species is highly dependent on sampling intensity, including the number of sampling trips.
