Biología     Glosario (por ej. epibenthic)

Adults occur in rubble and gravel riffles, less often in sand-gravel runs of headwaters, creeks and small rivers. Also found in springs and their effluents and rocky shores of lakes (Ref. 1998, 10294). Feed mainly on aquatic insect larvae, but also on crustaceans, annelids, fishes, fish eggs, and plant material (Ref. 1998, 10294). Spawn in the spring (Ref. 1998). A male guards the cluster of eggs laid by different females (Ref. 1998). Neither anterolateral glandular groove nor venom gland is present (Ref. 57406).

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

Male selects a nesting site under a rock of ledge. Male entices a female to enter the nest. Female deposits eggs on the upper surface of the rock and leaves or is driven out of the nest. Eggs are deposited by different females. The male guards the eggs from predators and maintains a natural current flow (Ref. 1998). Also Ref. 53335.

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00309 - 0.01700), b=3.13 (2.92 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.3   ±0.46 se; based on food items.
Resiliencia (Ref. 120179):  Alto, población duplicada en un tiempo mínimo inferior a 15 meses (tmax=2).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (34 of 100) .
