While studies have demonstrated that higher tree species richness can increase forest productivity, the relationships between tree species richness, tree growth and herbivore damage remain insufficiently explored. Here we investigate these linkages using data from 8,790 trees across 80 species in 9 biodiversity experiments, spanning temperate and subtropical biomes. Despite considerable geographic variation, we reveal an overall positive relationship between tree species richness and insect herbivory, as well as between tree growth and herbivory, at individual, species and community levels.

- Exotic plants generally show lower herbivore abundance and leaf damage compared to native species, but the reasons behind this are complex and may depend on community context.
- A comparison of European and North American tree species in both their native and exotic ranges showed consistent patterns of lower herbivory on exotic species across different conditions and locations.
- The findings suggest that while some lower herbivory is due to "enemy release," it is also influenced by the vulnerability of native plants to herbivores that have not co-evolved with them.
Genomic drift affects the functional properties of cell lines, and the reproducibility of data from in vitro studies. While chromosomal aberrations and mutations in single pivotal genes are well explored, little is known about effects of minor, possibly pleiotropic, genome changes. We addressed this question for the human dopaminergic neuronal precursor cell line LUHMES by comparing two subpopulations (SP) maintained either at the American-Type-Culture-Collection (ATCC) or by the original provider (UKN).
