Biology     Glossary (e.g. epibenthic)

An ubiquitous species which inhabits small to medium-sized streams. May be confined to very small pools during summer. Breeding occurs in shallow riffle habitats with fast-flowing water (Ref. 59043). Migration pattern is inferred from the behavior of other species in the same genus (Ref. 138297).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00402 - 0.01570), b=3.13 (2.97 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
