Selecting among competing statistical models is a core challenge in science. However, the
many possible approaches and techniques for model selection, and the conflicting …

The global biodiversity crisis has stimulated decades of research on three themes: species
coexistence, biodiversity–ecosystem functioning relationships (BEF), and biodiversity …

Globally increasing nitrogen (N) deposition is recognized as an important regulator of soil
microbial communities. However, how N enrichment affects soil microbial diversity, richness …

Nitrogen (N) and phosphorus (P) limitation constrains the magnitude of terrestrial carbon
uptake in response to elevated carbon dioxide and climate change. However, global maps …

Soil carbon transformation and sequestration have received significant interest in recent
years due to a growing need for quantitating its role in mitigating climate change. Even …

Ecosystems across the globe receive elevated inputs of nutrients, but the consequences of
this for soil fungal guilds that mediate key ecosystem functions remain unclear. We find that …

Plants invest a considerable amount of leaf nitrogen in the photosynthetic enzyme ribulose-
1, 5-bisphosphate carboxylase-oxygenase (RuBisCO), forming a strong coupling of nitrogen …

Niche dimensionality provides a general theoretical explanation for biodiversity—more
niches, defined by more limiting factors, allow for more ways that species can coexist …

Potassium (K+) is the most abundant inorganic cation in plant cells, playing a critical role in
various plant functions. However, the impacts of K on natural terrestrial ecosystems have …

Because the capability of terrestrial ecosystems to fix carbon is constrained by nutrient
availability, understanding how nutrients limit plant growth is a key contemporary question …
