Understanding how biodiversity affects functioning of ecosystems requires integrating
diversity within trophic levels (horizontal diversity) and across trophic levels (vertical …

Ecosystem productivity commonly increases asymptotically with plant species diversity, and
determining the mechanisms responsible for this well‐known pattern is essential to predict …

Species loss can impact ecosystem functioning, but no general framework for analyzing
these impacts exists. Here I derive a general partitioning of the effects of species loss on any …

General principles from coexistence theory are often invoked to explain how and why
mixtures of species outperform monocultures. However, the complementarity and selection …

Ecologists have long argued that higher functioning in diverse communities arises from the
niche differences stabilizing species coexistence and from the fitness differences driving …

Species' extinctions have spurred debate on whether interactions among few or among
