Anchiornis huxleyi, which is a member of the Middle–Late Jurassic Yanliao Biota, is the
smallest feathered dinosaur ever known. It has been described as a critical link between feathered
dinosaurs a...
Complete Mitochondrial Genome Sequences of Chinese Indigenous Sheep with Different Tail Types and an Analysis of Phylogenetic Evolution in Domestic Sheep
Mitochondrial DNA Mitogenome Sheep Phylogenetic Mitochondrial Control Region

Phylogenetic Analysis Chikso Haplotype mtDNA Cytochrome
2016/5/11
In order to analyze the genetic diversity and phylogenetic status of the Korean Chikso breed, we determined sequences of mtDNA cytochrome b (cyt b) gene and performed phylogenetic analysis using 239 i...
Phylogenetic Analysis of a Privately-owned Korean Native Chicken Population Using mtDNA D-loop Variations
D-loop Variation Haplotype Korean Native Chicken mtDNA
2016/5/11
The use of Korean native chicken is increasing, and the discovery of new genetic resources is very important from both economic and genetic conservation points of view. In this study, mtDNA D-loop seq...
Low-parameter phylogenetic estimation under the general Markov model
Markov invariants phylogenetic invariants base-composition rate-variation quartets supertrees
2012/5/2
In their 2008 and 2009 papers, Sumner and colleagues introduced the "squangles" - a small set of Markov invariants for phylogenetic quartets. The squangles are consistent with the general Markov model...
Distribution of branch lengths and phylogenetic diversity under homogeneous speciation models
phylogenetic tree birth–death process Yule model branch length
2011/9/23
Abstract: The constant rate birth--death process is a popular null model for speciation and extinction. If one removes extinct and non-sampled lineages, this process induces `reconstructed trees' whic...
The disentangling number for phylogenetic mixtures

2011/9/8
Abstract: We provide a logarithmic upper bound for the disentangling number on unordered lists of leaf labeled trees. This results is useful for analyzing phylogenetic mixture models. The proof depend...
What use are Exponential Weights for flexi-Weighted Least Squares Phylogenetic Trees?
Exponential Weights flexi-Weighted Least Squares Phylogenetic Trees
2011/1/5
The method of flexi-Weighted Least Squares on evolutionary trees uses simple polynomial or exponential functions of the evolutionary distance in place of model-based variances. This has the advantage ...
