Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805)
PD₅₀ = 1.5000 many relatives (e.g. carps) 0.5 - 2.0 few relatives (e.g. lungfishes)

Trophic Level (Ref. 69278)
3.6 ±0.5 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278)
Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100)

Vulnerability (Ref. 59153)
Very high vulnerability (76 of 100)

Price category (Ref. 80766)
