Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805)
PD₅₀ = 0.5000 many relatives (e.g. carps) 0.5 - 2.0 few relatives (e.g. lungfishes)

Trophic Level (Ref. 69278)
3.8 ±0.7 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278)
Very Low, minimum population doubling time more than 14 years (K=0.09(?); tm=5.1-8.4; tmax=105; Fec=19,815)

Vulnerability (Ref. 59153)
High to very high vulnerability (69 of 100)
