Methods

Data Editing- All museum data were obtained from FishNet 2. Points were mapped using ArcGIS 10.6.1 to create a geodatabase of species records. These files were analyzed using R (ggplot package) to flag erroneous points across the species’ range and were corrected. We then preformed a detailed visual examination of locality information in the target watersheds (Mobile Basin and the Tennessee and Cumberland River drainages), flagging erroneous points. Erroneous plots included incorrect geo-referencing of localities and likely mis-identifications of specimens (plotted outside of know range for a species). Data were also updated based on taxonomic changes (different genus, new species, or elevation of former subspecies to species status).  Corrections were made and recorded and shapefiles were updated. Corrections were reported back to the specific sources of these data (i.e. fish museums).

 

Public- Locality data and photo vouchers received from FIN Living Museum are stored on the servers. All photo vouchers and locality data are verified by experts. Once verified, data are uploaded to the appropriate species’ page. Uploads include new distribution/locality information and photo vouchers associated with these data.

 

Scientists- Scientists can apply to be an approved user of the back end scientific reporting portal. There they can view threatened and endangered species in more detail (including photo vouchers and locality information for the Living Museum). Scientists can also share data in this portal as well. Scientists choosing to contributing data may choose to not share this information with the public webpage (www.tnacifin.com), then only scientists with approved credentials will have access to these data.
