New molecular sequence data and species trees for North American whipsnakes [PDF]
Data in Brief, 2018 In this data article we present species trees based on coalescent species delimitation results for North American whipsnakes, as well as metadata pertaining to the article ''The effect of missing data on coalescent species delimitation and a taxonomic ...

Computational characterization and analysis of molecular sequence data of Elizabethkingia meningoseptica [PDF]
BMC Research Notes, 2022 Objective Elizabethkingia meningoseptica is a multidrug resistance strain which primarily causes meningitis in neonates and immunocompromised patients. Being a nosocomial infection causing agent, less information is available in literature, specifically,

Diversification of Neoaves: integration of molecular sequence data and fossils [PDF]
Biology Letters, 2006 Patterns of diversification and timing of evolution within Neoaves, which includes almost 95% of all bird species, are virtually unknown. On the other hand, molecular data consistently indicate a Cretaceous origin of many neoavian lineages and the fossil record seems to support an Early Tertiary diversification. Here, we present the first well-resolved

A molecular phylogeny of Hypnales (Bryophyta) inferred from ITS2 sequence-structure data [PDF]
BMC Research Notes, 2010 Background Hypnales comprise over 50% of all pleurocarpous mosses. They provide a young radiation complicating phylogenetic analyses. To resolve the hypnalean phylogeny, it is necessary to use a phylogenetic marker providing highly variable features to ...

Molecular Phylogenetics of Poaceae: An Expanded Analysis ofrbcL Sequence Data
Molecular Phylogenetics and Evolution, 1996 Phylogenetic analyses of rbcL sequence data from grasses are presented, extending the work of an earlier study. Based on molecular evidence that Joinvilleaceae and Restionaceae are closely allied to Poaceae, species from these families and from a ...

Molecular Sequence Data of Hepatitis B Virus and Genetic Diversity After Vaccination [PDF]
American Journal of Epidemiology, 2009 The effect of vaccination programs on transmission of infectious disease is usually assessed by monitoring programs that rely on notifications of symptomatic illness. For monitoring of infectious diseases with a high proportion of asymptomatic cases or a low reporting rate, molecular sequence data combined with modern coalescent-based techniques offer ...

BEAST: Bayesian evolutionary analysis by sampling trees [PDF]
BMC Evolutionary Biology, 2007 Background The evolutionary analysis of molecular sequence variation is a statistical enterprise. This is reflected in the increased use of probabilistic models for phylogenetic inference, multiple sequence alignment, and molecular population genetics ...

Fixed Character States and the Optimization of Molecular Sequence Data [PDF]
Cladistics, 1999 A method is proposed to optimize molecular sequence data that does not employ multiple sequence alignment. This method treats entire homologous contiguous stretches of sequence data as individual characters. This sequence is treated as the homologous unit employed in phylogeny reconstruction.

The detection of linkage disequilibrium in molecular sequence data. [PDF]
Genetics, 1995 Abstract Studies of genetic variation in natural populations at the sequence level usually show that most polymorphic sites are very asymmetrical in allele frequencies, with the rarer allele at a site near fixation. When the rarer allele at a site is present only a few times in the sample, say below five representatives, it becomes very ...
