Trait evolution with jumps: illusionary normality

The paper investigates evolutionary models with jumps on phylogenetic trees, introduces an extinction component, and demonstrates the mvSLOUCH package's simulation and visualization capabilities.

Phylogenetic effective sample size

The paper defines and compares phylogenetic effective sample sizes for Brownian motion and Ornstein-Uhlenbeck processes and evaluates the robustness of AICc with corrections for species number.

Phylogenetic confidence intervals for the optimal trait value

The paper develops confidence intervals for the optimal trait value under a stochastic evolutionary model with unknown phylogeny.

A Consistent Estimator of the Evolutionary Rate

The paper proposes an unbiased estimator for the evolutionary rate rho^2 = sigma^2/lambda using a branching particle system and derives an approximate standard error formula.

Quantifying the effects of anagenetic and cladogenetic evolution

The paper quantifies anagenetic and cladogenetic evolutionary effects using a framework that estimates speciational change and applies it to Hominoid body size.
