The phrase "a tree divided" is correct and usable in written English.
It can be used in contexts discussing division, separation, or conflict, often metaphorically.
Example: "In the debate over environmental policies, we find ourselves like a tree divided, with factions pulling in different directions."
Alternatives: "a split tree" or "a divided tree".
Possibly the earliest recorded index is the available growing space index (German: Wachsraumzahl) applied by (Seebach [1846])a, which is expressed by the observed crown diameter of a tree divided by its breast height diameter (dbh).
The proximity between two samples is calculated as the number of times the two samples end up in the same terminal node of a tree, divided by the number of trees in the forest.
The phylogenetic analyses of the CR sequences yielded a tree divided into three clades: Clade 1 has a high genetic distance to the other clades and contains the individuals of three populations which are separated by a watershed from all the others.
Different coding schemes have been suggested to decompose the gene trees into an MR: In the Baum-Ragan (BR) coding scheme, every gene tree topology is coded as follows [ 18, 19, 42]: An interior edge in a tree divides the taxa into two disjoint sets.
The CI of a character is the mimimum number of steps for that character on a given tree divided by the total number of steps reconstructed for that character on the same tree.
The other 47 complete putative cohesin sequences were aligned with cohesins from A. cellulolyticus and C. thermocellum (Additional file 1: Figure S1) and are presented on a phylogenetic tree, divided into type I and type II cohesins by sequence.
The phylogenetic tree divided StNACs into 18 distinct subgroups (NAC-a to NAC-r) along with their Arabidopsis and rice orthologs (Fig. 4).
The ancestry value is equal to the number of nodes from a given fold to the root of the tree divided by the number of nodes from the most recent fold to the root of the tree.
We define the DF of a topologically correct branch as the branch's length in the read tree divided by its length in the source tree.
To estimate plot level biomass, we estimated a biomass density at the plot centroid by summing the biomass estimates for each tree, divided by the 'plot area' of that tree.
Mean Rate: number of substitutions per site across the tree divided by the tree length.
