A phylogenetic tree (commonly known as an evolutionary tree or a phylogeny) is a diagram with branches that displays the evolutionary relationships between different biological species. Source: khanacademy.org History of Phylogenetic Trees Since a phylogenetic tree is known as the "tree of life," ...
or accessed through an accompanying webserver that can be installed locally. Here, we demonstrate PhaME’s ability to construct robust genus and species phylogenies using examples that span the tree of life, with up to thousands of genomes as input in the form of raw sequencing reads...
In this study, however, the indices of the two matrices are mapped to the same tree, the species tree. The justification and effect of using the species tree is explained in the text. Full size image Specifically, we use the species tree (reconstructed by neighbor-joining from a distance ...
Our results show that most of the variation in genome size could be explained by changes in the content of repetitive elements, contrary to non-repetitive regions. Moreover, DNA elements and short interspersed nuclear elements (SINEs) appear as the orders with the most significant differences in ...
The infection decreases with increasing age and the reasons are explained with the low level of exposure to HPV, limited nature of infection and the resistance resulted from the repeated infection. In their study conducted to detect HPV DNA positivity of women diagnosed with normal and abnormal ...
The obligate intracellular bacterium Chlamydia pneumoniae is a common respiratory pathogen, which has been found in a range of hosts including humans, marsupials and amphibians. Whole genome comparisons of human C. pneumoniae have previously highlighted
(SES.FD and NFRI) metrics, representing evolutionary histories and trait-related ecological processes. PC1, derived from phylogenetic metrics, explained 89.2% of the variation for SES.PD and NRI in Gyirong and 88.1% in Lebu. Both SES.PD and NRI exhibited strong correlations with PC1 (G...
(Supplementary Fig. S2)33, the low photosynthetic rate,Ks and Ψtlpof shrubs could only be explained by the intrinsic differences between shrubs and trees. For example, more branch junctions in shrubs might cause greater hydraulic constrictions42, higher WD, narrower vessels and greater LDMC in ...
The ancestral state reconstruction infers the evolutionary history of a trait along a phylogeny given the character states of species in the tree and provides estimates of the probable character state of each node in the phylogeny. This approach is based on a Markov model of evolution for discrete...
The tree of life is fundamental to understanding processes in evolutionary biology. Reconstructing different parts of the tree is therefore a major goal in this research area [1]. Today, evolutionary trees are most commonly reconstructed using DNA data from living representatives of the group of int...
