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.

Fast-slow traits predict competition network structure and its response to resources and enemies.

The paper shows that fast-slow growth strategies influence competition network structure and how it responds to nutrients and pathogens.

Climate, host and geography shape insect and fungal communities of trees

This study identifies climate, host-related, and geographic factors shaping insect and fungal communities on trees, showing climate change could impact these communities through host range shifts and human-mediated transport.

Loss of species richness with land use intensity is explained by a reduction in niche differences.

The paper shows that land use intensity reduces species richness by decreasing niche differences, not competitive inequalities, and highlights the importance of stabilizing interactions for biodiversity.

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.

Improved biodiversity detection using a large-volume environmental DNA sampler with in situ filtration and implications for marine eDNA sampling strategies

This study compares large-volume eDNA sampling with in situ filtration to small-volume conventional sampling, finding that larger samples detect more taxa and are better for deep ocean biodiversity detection.

Intraspecific trait changes have large impacts on community functional composition but do not affect ecosystem function

The paper quantifies how intraspecific trait shifts affect community functional traits and biomass production, finding they influence trait means but not ecosystem function.

Nitrogen availability and plant functional composition modify biodiversity-multifunctionality relationships

This study shows that plant species richness and functional diversity increase multifunctionality, but their effects depend on nitrogen availability and functional composition.

Assessing the impact of grassland management on landscape multifunctionality

This paper identifies optimal grassland compositions for ecosystem services using simulation and an online tool, showing that mixed intensity landscapes can maximize multifunctionality when services trade-off.

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.

A mechanistic path to maximize biomass productivity while maintaining diversity.

This study links coexistence mechanisms to biodiversity functioning by showing that stable coexisting plant communities produce more biomass, particularly under drought.

Decomposition disentangled: a test of the multiple mechanisms by which nitrogen enrichment alters litter decomposition

This study investigates how nitrogen enrichment affects litter decomposition by testing the relative roles of litter and soil quality, finding that litter quality is the main driver.

Domestication of Campylobacter jejuni NCTC 11168

This study compares genetic and phenotypic variation in 23 isolates of the reference Campylobacter jejuni strain NCTC 11168, showing significant genomic and phenotypic differences despite being considered identical.
