Phylogenomics resolves the timing and pattern of insect evolution
TLDR
The phylogeny of all major insect lineages reveals how and when insects diversified and provides a comprehensive reliable scaffold for future comparative analyses of evolutionary innovations among insects. Expand
Selecting optimal partitioning schemes for phylogenomic datasets
TLDR
These two novel methods for estimating best-fit partitioning schemes on large phylogenomic datasets are developed: strict and relaxed hierarchical clustering, which provide the best current approaches to inferring partitions on very large datasets. Expand
Evolutionary History of the Hymenoptera
TLDR
The results reveal that the extant sawfly diversity is largely the result of a previously unrecognized major radiation of phytophagous Hymenoptera that did not lead to wood-dwelling and parasitoidism. Expand
Structural and Kinetic Analysis of Bacillus subtilis N-Acetylglucosaminidase Reveals a Unique Asp-His Dyad Mechanism*
TLDR
These findings will facilitate the development of mechanism-based inhibitors that selectively target family 3 β-N-acetylglucosaminidases, which are involved in bacterial cell wall turnover, spore germination, and induction of β-lactamase. Expand
Visualizing differences in phylogenetic information content of alignments and distinction of three classes of long-branch effects
TLDR
It is shown that tree topologies and popular support values do not show existing differences in data quality and an exploratory analysis of the signal to noise ratio can be conducted with split decomposition methods. Expand
Pan genome of the phytoplankton Emiliania underpins its global distribution
TLDR
Comparisons across strains demonstrate that E. huxleyi, which has long been considered a single species, harbours extensive genome variability reflected in different metabolic repertoires, and reveals a pan genome (core genes plus genes distributed variably between strains) probably supported by an atypical complement of repetitive sequence in the genome. Expand
Automatic selection of partitioning schemes for phylogenetic analyses using iterative k-means clustering of site rates
TLDR
A new algorithm is presented that automatically selects a partitioning scheme via the iterative division of the alignment into subsets of similar sites based on their rates of evolution, and it consistently leads to large increases in the fit of partitioned models of molecular evolution when measured using AICc and BIC scores. Expand
Cryptic mitochondrial lineages in the widespread pycnogonid Colossendeis megalonyx Hoek, 1881 from Antarctic and Subantarctic waters
TLDR
The data strongly support that nominal Colossendeis megalonyx consists of at least five cryptic and one pseudocryptic mitochondrial lineages, four of which appear to be geographically restricted, thus indicating high levels of gene flow or recent colonization in the Antarctic. Expand
Phylogenomics reveals the evolutionary timing and pattern of butterflies and moths
TLDR
It is demonstrated that the most recent common ancestor of Lepidoptera is considerably older than previously hypothesized, and it is shown that multiple lineages of moths independently evolved hearing organs well before the origin of bats, rejecting the hypothesis that lepidopteran hearing organs arose in response to these predators. Expand
Multiple origins of deep-sea Asellota (Crustacea: Isopoda) from shallow waters revealed by molecular data
TLDR
The molecular data support the monophyly of most deep-sea families and give evidence for a multiple colonization of the deep sea by at least four major lineages of asellote isopods. Expand
