A surrogate function for one-dimensional phylogenetic likelihoods
, 2017 Phylogenetics has seen an steady increase in substitution model complexity, which requires increasing amounts of computational power to compute likelihoods.

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1989 A new statistical method called the phylogenetic regression is proposed that applies multiple regression techniques to cross-species data. It allows continuous and categorical variables to be tested for and controlled for. The new method is valid despite the problem that phylogenetically close species tend to be similar, and is designed to be used when

Encyclopedia of Bioinformatics and Computational Biology, 2019 We report here the discovery of a remarkable new monotypic mygalomorph spider genus, known only from one geographical location along the central coast of California. The single relict species comprising Cryptocteniza kawtak n. gen. n. sp.

Phylogenetics of Allopolyploids [PDF]
Annual Review of Ecology, Evolution, and Systematics, 2017 We give an overview of recently developed methods to reconstruct phylog-enies of taxa that include allopolyploids that have originated in relatively recent times—in other words, taxa for which at least some of the parental lineages of lower ploidy levels are not extinct and for which ploidy information is clearly shown by variation in chromosome counts.

BMC Ecology and EvolutionBackground The evolution of differences in gamete size and number between sexes is a cornerstone of sexual selection theories. The green macroalga Ulva, with incipient anisogamy and parthenogenetic gametes, provides a unique system to investigate ...

Marginal Likelihoods in Phylogenetics: A Review of Methods and Applications [PDF]
Systematic Biology, 2018 By providing a framework of accounting for the shared ancestry inherent to all life, phylogenetics is becoming the statistical foundation of biology.

Population Ecology, EarlyView.Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size

An Annealed Sequential Monte Carlo Method for Bayesian Phylogenetics. [PDF]
Systematic Biology, 2018 We describe an "embarrassingly parallel" method for Bayesian phylogenetic inference, annealed Sequential Monte Carlo (SMC), based on recent advances in the SMC literature such as adaptive determination of annealing parameters.

FEBS Letters, EarlyView.The Arabidopsis mutants hls1 hlh1 and amp1 lamp1 exhibit pleiotropic developmental phenotypes. Although the functions of the causative genes remain unclear, they act in the same genetic pathway and are thought to generate non‐cell‐autonomous signals.
