Biologia     Glossário (p.ex. epibenthic)

Facultative air-breathing (Ref. 126274); Occur in swift-flowing, tea-colored streams coursing through karri forests. Also found in swamps, ponds and roadside ditches. Usually lives in small flowing streams near submerged vegetation. Water inhabited is darkly tannin-stained and acidic (pH 3.0-6.0) (Ref. 44894). Feed on insects and their larvae in water; also on micro-crustaceans. Spawning has been recorded from July to October, peaking between August and September when water temperatures and day length are on the rise. Multiple-spawning females deposit several clutches of eggs over a protracted period of a few weeks in flooded vegetation. Sexual maturity is attained in the first year. Spent adults usually die a few months after spawning (Ref. 44894).

Estimates based on models

Índice de diversidade filogenética (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00205 - 0.01170), b=3.12 (2.91 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  3.2   ±0.36 se; based on food items.
Resiliência (Ref. 120179):  médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (K=3.70; tm=1; tmax=1; mean Fec=65).
