Disentangling the mechanisms by which nitrogen enrichment affects consumer damage at different organisational levels

This study investigates how nitrogen enrichment affects consumer damage across different organisational levels in grasslands, finding that community characteristics are more influential than nitrogen enrichment.

Plant attributes interact with fungal pathogens and nitrogen addition to drive soil enzymatic activities and their temporal variation

The paper measures soil enzyme activities across seasons and years to assess how nitrogen enrichment, plant attributes, and fungal pathogens influence their temporal dynamics and stability.

Plant-invertebrate interactions across a forested retrogressive chronosequence

The paper examines how nutrient availability and predator abundance influence invertebrate herbivore biomass across a retrogressive forest chronosequence, revealing a shift from bottom-up to top-down control.

Sick plants in grassland communities: a growth-defense trade-off is the main driver of fungal pathogen abundance and impact

The paper shows that a growth-defense trade-off drives fungal pathogen abundance and impact in grasslands, with nitrogen addition and fungicide use altering these dynamics.

Rare species perform worse than common species under changed climate

This study transplants rare and common plant species to different climates and finds rare species have lower survival and biomass under novel conditions, especially when precipitation differs from their natural range.

Context dependency of biotic interactions and its relation to plant rarity

The paper examines how biotic interactions influence plant rarity and commonness, finding that widespread species from resource-rich habitats are less defended against herbivores than those from resource-poor habitats, while rare species lack this tradeoff.
