Bayes factors were calculated with marginal likelihood estimated with stepping-stone sampling.

We found striking differences in age estimates and diversification dynamics depending on prior choice.

With recent advances in Bayesian clock dating methodology and the explosive accumulation of genetic sequence data, molecular clock dating has found widespread applications, from tracking virus pandemics and studying the macroevolutionary process of speciation and extinction to estimating a timescale for life on Earth.

Asterophryinae is a large monophyletic subfamily of Anurans containing over 300 species distributed across one of the world's most geologically active areas – New Guinea and its satellite islands, Australia and the Philippines.

Here we set to review the diversity, biodiversity patterns and biogeography of karst endemic plants of a number of families (Elatostema, Orchidea, Urticaceae, Gesneriaceae) across China and surrounding regions and understand specific aspects of their adaptive ecology.

From this we move to reviewing relative threats, and regional prioritorisation for karst flora and discuss mechanisms for the development and implementation appropriate conservation initiatives to secure a better future for China’s karst flora.

Therefore, dating phylogenies has become a standard practice in phylogenetic, biogeographic, ecological, and other evolutionary studies (Pisani et al., 2004; Benton and Donoghue, 2007; Donoghue and Benton, 2007; Laurin, 2012). dating ancestors in phylogenetic trees in R. This software is now a part of ape package available at cran. The tremendous ecological and morphological diversity of this clade, with apparent specializations for burrowing, terrestrial, semi-aquatic, and arboreal lifestyle, suggests an evolutionary process of adaptive radiation.Despite this spectacular diversity, this and many other questions of evolutionary processes have received little formal study because until now the phylogeny of this spececies-rich clade has remained uncertain.We investigated the effect of branching priors using the iconic cycads.
