Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

North America: Green, Cumberland and Tennessee River drainages in central Kentucky to northern Alabama, USA; upper Mississippi River basin from southern Wisconsin and southern Minnesota to Ozark and Ouachita Highlands of Arkansas, Kansas and Oklahoma in USA.

Biology     Glossary (e.g. epibenthic)

Inhabits rocky riffles, runs, and flowing pools of clear creeks and small rivers. Rarely found in springs and along wave-swept margins of large impoundments (Ref. 5723, 10294). Feeds on aquatic insect immatures (midges, mayflies, caddisflies) and small crustacea (isopods, amphipods, copepods) (Ref. 10294).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates for this BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (tmax=4).
Vulnerability (Ref. 59153):  Low vulnerability (24 of 100) .
Price category (Ref. 80766):   Unknown.
