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 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=0.00871 (0.00383 - 0.01980), b=3.06 (2.85 - 3.27), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.3   ±0.27 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.35).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (34 of 100) .
Price category (Ref. 80766):   Unknown.
