Additionally, by applying a semi-analytic galaxy formation model to the augmented trees we have shown that galaxy properties converge as tree resolution is increased, and that we can successfully augment trees from a low resolution simulation to match the resolution of a higher resolution simulation and that the resulting galaxy properties are in excellent agreement between the two cases.
West Harlem has a low tree canopy.
The user can change the tree resolution by modifying the parameters of the tree condensation protocol.
More generally, our results suggest that the low support at the base of the rodent tree cannot be attributed only to the presence of conflicting non-phylogenetic signal, since removing such non-phylogenetic signal failed to significantly increase the tree resolution.
Remove brush and low tree branches.
In this case, sequence identity at the nucleotide level is very high, which gives rise to gene trees with low resolution, a fact that further complicates the task of inferring the strain tree.
Although the NTI for all species showed almost the same trend as the NRI in this study, this should be interpreted carefully for the NTI calculated from low resolution trees such as in our study (Swenson 2009).
The Acc1 gene sequence divergence was also generally relatively low, ranging from 0.2% in many cases to 3.3% (subclade A, 0.3%-1.9%; subclade D, 0.2%-2.0%; subclade E, 0.3%-1.3%), which resulted in low branching resolution in the phylogenetic trees.
However, both trees showed polytomy (low resolution) between the Thailand (Southern Lineage I) and Korean/Japanese/Taiwanese (Northern Lineage) populations and between the Thailand and Indian populations (Figure 4).
Moreover, some previous studies have reported phylogenetic trees with a low resolution, especially in the deep lineages, due to a lack of suitable nucleotide and amino acid substitution rates and other factors.
