Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.00525 (0.00238 - 0.01156), b=3.15 (2.96 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
3.4 ±0.5 se; based on size and trophs of closest relatives |
|
Resilience (Ref. 120179) |
High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.). |
