Data from: Climatic forcing of Quaternary deep-sea benthic communities in the North Pacific Ocean

Moriaki Yasuhara, Gene Hunt, Thomas M. Cronin, Natsumi Hokanishi, Hodaka Kawahata, Akira Tsujimoto & Miho Ishitake
There is a growing evidence that changes in deep-sea benthic ecosystems are modulated by climate changes, but most evidence to date comes from the North Atlantic Ocean. Here we analyze new ostracod and published foraminiferal records for the last 250,000 years on Shatsky Rise in the North Pacific Ocean. Using linear models, we evaluate statistically the ability of environmental drivers (temperature, productivity, and seasonality of productivity) to predict changes in faunal diversity, abundance and composition....

Data from: Associated evolution of bipedality and cursoriality among Triassic archosaurs: a phylogenetically controlled evaluation.

Tai Kubo & Mugino O. Kubo
Bipedalism evolved more than twice among archosaurs, and it is a characteristic of basal dinosaurs and a prerequisite for avian flight. Nevertheless, the reasons for the evolution of bipedalism among archosaurs have barely been investigated. Comparative analysis using phylogenetically independent contrasts showed a significant correlation between bipedality (relative length of forelimb) and cursoriality (relative length of metatarsal III) among Triassic archosaurs. This result indicates that, among Triassic archosaurs, bipeds could run faster than quadrupeds. Bipedalism...

Smith, Jessica M. Theodor, Rachel C. M. Warnock, Michael J. Benton … & Louis Jacobs
Our ability to correlate biological evolution with climate change, geological evolution, and other historical patterns is essential to understanding the processes that shape biodiversity. Combining data from the fossil record with molecular phylogenetics represents an exciting synthetic approach to this challenge. The first molecular divergence dating analysis (Zuckerkandl and Pauling 1962) was based on a measure of the amino acid differences in the hemoglobin molecule; with replacement rates established (calibrated) using inaccurate paleontological age estimates...

Data from: Taxon Influence Index: assessing taxon-induced incongruities in phylogenetic inference

Mahendra Mariadassou, Avner Bar-Hen & Hirohisa Kishino
Understanding the evolutionary history of species is at the core of molecular evolution and is done using several inference methods. The critical issue is to quantify the uncertainty of the inference. The posterior probabilities in Bayesian phylogenetic inference and the bootstrap values in frequentist approaches measure the variability of the estimates due to the sampling of sites from genes and the sampling of genes from genomes. However, they do not measure the uncertainty due to...
