North America: Mississippi River basin from Ohio and West Virginia to eastern Illinois and south to Louisiana in the USA; Gulf drainages from Black Warrior River in Alabama to Guadalupe River in Texas, USA.

Biology     Glossary (e.g. epibenthic)

Inhabit fast gravel runs, sometimes riffles, of creeks and small to medium rivers. Often found near brush (Ref. 5723, 10294). Young are found in shallower gravel riffles (Ref. 7043). Juveniles feed on midge and blackfly larvae; adults consume caddisfly and mayfly larvae (Ref. 10294). Males are larger and darker in color during breeding (Ref. 69400).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.40 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (tmax=4; tm=1; Fec=80-196).
Vulnerability (Ref. 59153):  Low vulnerability (16 of 100) .
Price category (Ref. 80766):   Unknown.
