The size–grain hypothesis and interspecific scaling in ants
1. The size–grain hypothesis maintains that as terrestrial walking organisms decrease in size, their environment becomes less planar and more rugose. The benefits of long legs (efficient, speedyExpand

Ecological morphospace of New World ants
Abstract.  1. Here the quantitative relationships between ecology, taxonomy, and morphology of ant workers are explored. The morphospace for worker ants taken from 112 genera and 12 subfamilies ofExpand

Empirical evaluation of neutral theory.
We describe a general framework for testing neutral theory. We summarize similarities and differences between ten different versions of neutral theory. Two central predictions of neutral theory areExpand

Extreme genetic differences between queens and workers in hybridizing Pogonomyrmex harvester ants
The process of reproductive caste determination in eusocial insect colonies is generally understood to be mediated by environmental, rather than genetic factors. We present data demonstratingExpand

Functional beta‐diversity patterns reveal deterministic community assembly processes in eastern North American trees
Aim Determining the relative influence of niche-based and neutral processes in driving the spatial turnover of community composition is a central challenge in community ecology. Spatial patternsExpand

Variation in above-ground forest biomass across broad climatic gradients
AimAn understanding of the relationship between forest biomass and climate is needed to predict the impacts of climate change on carbon stores.Biomass patterns have been characterized atExpand

Temperature mediates continental-scale diversity of microbes in forest soils
Climate warming is increasingly leading to marked changes in plant and animal biodiversity, but it remains unclear how temperatures affect microbial biodiversity, particularly in terrestrial soils.Expand

The latitudinal species richness gradient in New World woody angiosperms is consistent with the tropical conservatism hypothesis
Significance The diversity of living things generally peaks in the tropics and declines toward the poles. This “latitudinal gradient” is Earth’s most prevalent biogeographic pattern, but biologistsExpand

Tree height–diameter allometry across the United States
The relationship between tree height and diameter is fundamental in determining community and ecosystem structure as well as estimates of biomass and carbon storage. Yet our understanding of how treeExpand

Climatic drivers of hemispheric asymmetry in global patterns of ant species richness.
Although many taxa show a latitudinal gradient in richness, the relationship between latitude and species richness is often asymmetrical between the northern and southern hemispheres. Here we examineExpand
