Species and genetic diversity promote tree community productivity by increasing functional diversity and reducing herbivore damage and soil fungal diversity.

Genetic effects on body weight in mice are highly heterogeneous, dynamic, and nonlinear with respect to genomic background, age, and diet.

Hawaiian Caenorhabditis elegans harbor high levels of genetic diversity that might represent the complex patterns of ancestral diversity in the species prior to human influence.

Characterisation of within-host diversity of SARS-CoV-2 provides insights into the mutational and selective mechanisms driving its evolution and has important implications for using within-host variation to inform transmission inference efforts.

Phenotypic diversity and cell state transition (i.e., acquisition of a CD44+/CD24- cell state or exposure to TGF-beta) can spur intra-tumor genetic heterogeneity and contribute to acquired resistance.

Application of museomics facilitates characterization of the contribution of historical factors to genetic diversity declines in Numenius shorebirds and highlights that extinction of ecosystem-engineering megafauna may have been detrimental for open-landscape species.

Quantifying the relationship between census sizes and genetic diversity estimates provides insights into whether natural selection can explain the narrow range of diversity between species.

Genetic diversity is strongly associated with ecosystem functions across natural trophic chains, showing that it can be as important as species diversity.

Genetics of a canine transmissible tumour show how the world’s oldest cancer “metastasised” through the global dog population – and captured, maintained and rearranged its mitochondrial DNA along the way.

A genomic, climatic, agronomic, and participatory characterization of teff agrobiodiversity shows opportunities and challenges of teff improvement in the face of climate change.
