TL;DR: This article conducted a standardized sampling in 48 herbaceous-dominated plant communities on five continents and found no clear relationship between productivity and fine-scale (meters−2) richness within sites, within regions, or across the globe.

TL;DR: In this paper, the authors show that plant species diversity decreased when a greater number of limiting nutrients were added across 45 grassland sites from a multi-continent experimental network, even after controlling for effects of plant biomass, and even where biomass production was not nutrient-limited.

TL;DR: It is suggested that species origin has functional significance, and that eutrophication will lead to increased exotic dominance in grasslands.

TL;DR: This work presents a framework that describes how different forms of stochasticity combine to provide underlying and predictable structure in diverse communities, and proposes next steps that ecologists might use to explore the role of stoChasticity for structuring communities in theoretical and empirical systems, and thereby enhance the understanding of community dynamics.

TL;DR: This work applied a population model representing a freshwater amphipod feeding on leaf litter in forested streams to simulate impacts of hypothetical stressors, individually and in pairwise combinations that target the individuals' feeding, maintenance, growth and reproduction.
