Biology     Glossary (e.g. epibenthic)

Found in lakes, rivers and streams between 0 and 600 m elevation. The young feed on terrestrial and aquatic insects, leaves, fruits and seeds but become mainly herbivorous when adult. Eggs are deposited in nests located in sand bottoms of streams.

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=0.00933 (0.00545 - 0.01597), b=3.03 (2.88 - 3.18), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.3   ±0.27 se; based on food items.
Generation time: 3.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.35; Fec = 701;).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (34 of 100).
