Phylogenetic trees support the coevolution of parasites and their hosts.
Visible in the distance are ruins and palm trees.
Experiments were conducted in a turfgrass area on a 0.5-ha residential property, with scattered trees and adjacent woodlots.
All other components have size n2/3 and are either trees or unicyclic.
In this paper, we will focus on recursive trees and binary search trees as underlying classes of trees.
Our refined approaches will also exhibit some universality; we will demonstrate this by showing that they straightforwardly apply to random binary search trees as well.
Moreover, for some cases involving trees we estimate the smallest quantifier depth of a defining formula up to a factor of 1 + o(1).
Parse trees for those matroids were introduced by the author in [4].
