Biology     Glossary (e.g. epibenthic)

Inhabits flowing pools and gravel runs of creeks and small to medium rivers. Also occurs in rocky margins of lakes (Ref. 86798). Young-of-the-year feed mostly on dipterous larvae; yearlings feed on aquatic insect larvae (mostly Ephemeroptera and Diptera) during the months of June and July switching to terrestrial insects in September; adults more than 2 years also feed on aquatic insect larvae, (Ephemeroptera and Diptera), terrestrial insects, and earthworms (Lumbricus) displaced from the soil (Ref. 1998). Spawning occurs early July (Ref. 1998).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00232 - 0.01084), b=3.13 (2.94 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.7   ±0.26 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
