This paper evaluates robust Random Forests for genomic prediction under contamination, finding data transformation as the most effective strategy for improving performance in contaminated datasets.

This study sequenced impala genomes to investigate evolutionary stasis, finding genetic structure and reduced natural selection in eastern populations compared to southern African ones.

This paper compares machine learning methods for genomic prediction using synthetic and empirical data, finding that no single method outperforms others consistently and that classical methods remain competitive.

The paper evaluates robust and classical methods for estimating heritability and predictive accuracy in plant breeding using simulations and empirical data, finding robust methods more reliable in contaminated data.

The paper assesses the status and threats to wildebeest migration in East Africa, finding that land use changes and human activities have severely disrupted migration patterns in most ecosystems.
