TL;DR: Strong support for monophyly of groups corresponding closely to many previously recognized tribes and subfamilies is found, but no previous classification was entirely supported, and relationships among the strongly supported clades were weakly resolved and/or conflicted between some data sets.

TL;DR: This study estimated the phylogeny for 534 Rubiaceae taxa from 329 genera with up to five different chloroplast regions by Bayesian analysis, resulting in a highly resolved tree with many strongly supported nodes.

TL;DR: Crypteroniaceae are the first plant group for which the out-of-India hypothesis is well corroborated by molecular-based estimates of divergence times and are also the first to be identified as a sister to a clade formed by three small African taxa.

TL;DR: The number of cyanobacterial phylotypes showed a seasonal variation and reached a peak in September, both in the upper and deeper soil fractions, while some cyanob bacterial sequences were only present during the rice growth season, while others were only found after harvest.

TL;DR: A recently developed fossil cross-validation method is expanded on to evaluate whether alternative nodal assignments of multiple fossils produce calibration sets that differ in their internal consistency, finding that a correlation exists between s values, devised to measure the consistency among the calibration points of a calibration set, and nodal distances among calibration points.
