Jointly representing long-range genetic similarity and spatially heterogeneous isolation-by-distance

This paper introduces a method to identify long-range genetic similarities in genetic data while accounting for spatially heterogeneous isolation-by-distance patterns, validated on human and gray wolf datasets.

Allele ages provide limited information about the strength of negative selection

This paper shows that allele ages provide limited additional information about the distribution of fitness effects beyond what is already captured by allele frequencies.

Model-based genotype and ancestry estimation for potential hybrids with mixed-ploidy

The paper extends a Bayesian model to estimate genotype and ancestry in autopolyploid and mixed-ploidy individuals using low-depth sequencing data.

Dirichlet-multinomial modelling outperforms alternatives for analysis of microbiome and other ecological count data

This study shows that Dirichlet-multinomial modelling outperforms other methods in detecting differences in relative abundances in ecological count data, with HMC providing the most accurate results.
