Evolutionary Relationships of Wild Hominids Recapitulated by Gut Microbial Communities
Although bacteria are continually acquired over the lifetime of an individual, the phylogenetic relationships of great ape species is mirrored in the compositions of their gut microbial communities.
bottlesim: a bottleneck simulation program for long-lived species with overlapping generations
Population bottlenecks reduce genetic diversity and thus cause great concern in conservation biology. Previous theoretical studies often assume discrete generations in projecting declines in geneticExpand
VgrG C terminus confers the type VI effector transport specificity and is required for binding with PAAR and adaptor–effector complex
Significance The type VI secretion system involves multiple strategies for effector delivery via fusion or interaction of effectors to structural components of the phage tail-like structure, the tubeExpand
The consequences of genetic drift for bacterial genome complexity.
Genetic drift, which is particularly effective within small populations, can shape the size and complexity of genomes by affecting the fixation of deleterious mutations. In Bacteria, assessing theExpand
The Apicomplexan Whole-Genome Phylogeny: An Analysis of Incongruence among Gene Trees
The protistan phylum Apicomplexa contains many important pathogens and is the subject of intense genome sequencing efforts. Based upon the genome sequences from seven apicomplexan species and aExpand
Genetic Effects of a Persistent Bottleneck on a Natural Population of Ornate Box Turtles (Terrapene ornata)
Human activities in the past few hundred years have caused enormous impacts on many ecosystems, greatly accelerating the rate of population decline and extinction. In addition to habitat alterationExpand
The Extinction Dynamics of Bacterial Pseudogenes
Pseudogenes are usually considered to be completely neutral sequences whose evolution is shaped by random mutations and chance events. It is possible, however, for disrupted genes to generateExpand
The Alveolate Perkinsus marinus: Biological Insights from EST Gene Discovery
BackgroundPerkinsus marinus, a protozoan parasite of the eastern oyster Crassostrea virginica, has devastated natural and farmed oyster populations along the Atlantic and Gulf coasts of the UnitedExpand
Inferring clocks when lacking rocks: the variable rates of molecular evolution in bacteria
BackgroundBecause bacteria do not have a robust fossil record, attempts to infer the timing of events in their evolutionary history requires comparisons of molecular sequences. This use of molecularExpand
Comparative Analysis of the Peanut Witches'-Broom Phytoplasma Genome Reveals Horizontal Transfer of Potential Mobile Units and Effectors
Phytoplasmas are a group of bacteria that are associated with hundreds of plant diseases. Due to their economical importance and the difficulties involved in the experimental study of these obligateExpand
