Biology     Glossary (e.g. epibenthic)

Found in landlocked basins. Usually with T. arcticus, with which it possibly interbreeds (Ref. 593). Omnivore, occasionally predatory. In autumn and winter it forms large shoals at the entrance of rivers and streams into lakes (Ref. 41072).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00358 - 0.02025), b=3.07 (2.87 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.29; tm=5-6).
Vulnerability (Ref. 59153):  Moderate vulnerability (37 of 100) .
