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

North America: lower Great Lakes and Mississippi River basins from Pennsylvania to Minnesota in the USA and south to Gulf; Atlantic and Gulf Slope drainages from Cape Fear River in North Carolina to Colorado River in Texas, USA (absent from most of peninsular Florida).

Biology     Glossary (e.g. epibenthic)

Inhabits long deep pools of small to medium rivers over clay, sand or gravel. Occasionally found in creeks, large rivers and impoundments (Ref. 5723). Feeds on organic detritus, copepods, cladocerans, midge larvae and diatoms (Ref. 10294).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00606 - 0.01727), b=3.00 (2.85 - 3.15), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.47 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (tmax=6).
Vulnerability (Ref. 59153):  High vulnerability (57 of 100) .
