Ipomoea arborescens
3 equations apply to this species, 1 fitted on it directly. Each output lists them most specific first: fitted on this species, then on a variety of it, then pooled fits that included it, then its genus and its family. Within each step, equations the authors advised against go last, then those read from compilations; more trees come first.

Fitted on this species · 8 trees · DBH 8–32.4 cm · Read from the original paper

Pooled fit on 5 species, this one included · Number of trees not stated · DBH 3.5–32.9 cm · Read from the original paper
- Five-species pooled AGB from dbh (Table 4)DBHMexico
Its authors advise against it: “Comparison of the regression parameter homogeneity of the five species determined rejection of the null hypothesis, and thus, a single model cannot be fit satisfactorily to the database of the species involved in the present study” (Results, p. 8)

- Lower wood density subgroup (CEI) AGB from dbh (Table 4)DBHMexico
Its authors advise against it: “Thus, it is only possible to use a single equation for the species of the first subgroup, but not for those of the second or all species together (Table 4).” (Results, p. 8)

General equations that may apply (18)
Fitted on many species across the tropics or the world, so not ranked against the ones above. Pantropical ones show only when this species's own fits come from the tropics, for the same tree type. Check that your trees fall inside each one's range before using it.
