Biology     Glossary (e.g. epibenthic)

Occurs among cobbles and rocks in swiftly flowing water. Active at night, feeding on benthic stream invertebrates such as mayfly and midge larvae. Breeds in summer. Iteroparous, with asynchronous ovarian development (Ref. 51405). Preyed upon by trout and is now scarce in certain streams (Ref. 7248).

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=0.00447 (0.00174 - 0.01147), b=3.09 (2.86 - 3.32), in cm Total Length, based on LWR estimates for this (Sub)family-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 (Fec=600).
Vulnerability (Ref. 59153):  Moderate vulnerability (38 of 100) .
