Abstract:
We
summarize the results of our study on the status of the southern cavefish
(Typhlichthys subterraneus) in Arkansas. Its presence in the state
represents the western-southern limits of its distribution. Four localities
have been confirmed that contain individuals of this species: Richardson
Cave (Fulton County), Alexander Cave/Clark Spring (Stone County),
Ennis Cave (Stone County), and Lake Norfork (Baxter County). A fifth
locality has been cited as a well in Randolph County, but because the
exact location is unknown, its presence has not been confirmed. A
number of unconfirmed localities for "cavefishes" in the region has not
been included in this report. Populations of this species in Arkansas seem
to be small (less than 100 individuals) which is common among
populations of hypogean amblyopsids elsewhere. All the confirmed
localities are in areas either under controlled access by the private owners
or by the federal government. No immediate threat to these populations
was found by either overcollecting or other anthropogenic causes. Yet
long-term monitoring of the recharge zones is recommended
