Nutrient enrichment and herbivore exclusion disrupt the climate-driven balance between C3 and C4 plants in grasslands

The paper shows that nutrient enrichment, especially with nitrogen and phosphorus, reduces C4 plant cover in grasslands, disrupting climate-driven C3-C4 balance globally.

Acoustic detection of a rarely vocalising invasive mammal from sparse data

The paper develops a lightweight acoustic classifier for detecting rare vocalisations of the invasive small Indian mongoose using sparse data, but finds limited utility due to small training datasets.

Quantifying the net effect of biodiversity on stability

The paper quantifies how biodiversity affects ecosystem stability using simulations and experiments, finding stability often exceeds expectations due to diversity.
