Biology     Glossary (e.g. epibenthic)

This species could be considered as critically endangered following IUCN criteria (Ref. 57144). Excessive ground water withdrawal for agricultural purposes, the drying of wetlands, and water pollution are, along with the introduced Gambusia, the major threats to the survival of this species (Ref. 57144).

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=0.00933 (0.00412 - 0.02112), b=3.23 (3.05 - 3.41), based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
Price category (Ref. 80766):   Unknown.
