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

North America: Great Lakes-St. Lawrence River, Hudson Bay and Mississippi River basins from Quebec to Alberta in Canada and south to northern Alabama and Oklahoma in the USA; Atlantic Slope drainages from Hudson River in New York to Santee River in South Carolina, USA.

Biology     Glossary (e.g. epibenthic)

Inhabit rocky pools, runs and riffles in small to large rivers. Also occur in lakes (Ref. 5723, 10294). Adults feed on benthic insect larvae; juveniles consume microcrustacea and midge larvae (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=0.01148 (0.00624 - 0.02112), b=2.97 (2.80 - 3.14), based on LWR estimates for species & Genus-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.1   ±0.41 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (tmax=9).
Vulnerability (Ref. 59153):  High to very high vulnerability (65 of 100) .
Price category (Ref. 80766):   Unknown.
