Scientists use a tool called a phylogenetic tree to show the evolutionary pathways and connections among organisms. Aphylogenetic treeis a diagram used to reflect evolutionary relationships among organisms or groups of organisms. Scientists consider phylogenetic trees to be a hypothesis of the evolutionary...
Previously, we published an analysis of 149 genomes of 78 different species isolated from the female bladder [14]. Several of the taxa found within the bladder microbiota are also inhabitants of the vaginal microbiota [14,21,22]. This led us to posit that the bacterial communities of these t...
Cave organisms occupy a special place in evolutionary biology because convergent morphologies of many species demonstrate repeatability in evolution even a... ML Niemiller,BM Fitzpatrick,BT Miller - 《Molecular Ecology》 被引量: 445发表: 2008年 Towards a new classification of the Arthoniales (Ascomyc...
This notably leaves out incompletely sampled trees and sequentially sampled trees (e.g. trees for fast-evolving organisms or trees including fossil character data). It is understood that the models specific to such trees will not be presented in this paper. When referring to the whole species ...
For site-rate calculations, we provided the consensus of the posterior distribution of trees resulting from the BEAST analyses and the respective mtDNA or nDNA alignments as inputs. In comparison to the consen- sus tree, using a subsample of trees from the posterior distri- bution inferred from...
Sequencing projects have allowed diverse retroviruses and LTR retrotransposons from different eukaryotic organisms to be characterized. It is known that retroviruses and other retro-transcribing viruses evolve from LTR retrotransposons and that this whol
Again, the strong dispersal capacities of microscopic organisms can explain this observation. At the investigated scale, the dispersal rate of diatoms is high enough to obscure any geographical signature of historical colonization or local diversification. Our study offers new insight into the community ...
Consequently, these few examples stress the value in sys- tematics of developing phylogenetic approaches aimed at testing multiple relationships, possible and impossible alike: accounting both for the limited as well as for the conflictual resolutions between multiple gene trees. Epistemological principles...
Genes from more basal organisms (arthropods and nematodes) show a more variable structure in terms of intron number and position; no significant similarities with vertebrate genes were noted at the level of gene structure. Unsurprisingly, we observe similar gene structures also between pairs of ...
Phylogenetic reconstruction of its monogenean parasites belonging to Cichlidogyrus covered nearly all nominal tropheine host species and resulted in a clear pattern of host-specificity and congruence between host and parasite trees. We explore how parasite diversity relates to the biology of the ...
