A general model of ecosystem respiration based on the kinetics of metabolic reactions and the scaling of resource use by individual organisms is derived, predicting that fluxes of CO2 and energy are invariant of ecosystem biomass, but are strongly influenced by temperature, variation in cellular metabolism and rates of supply of limiting resources.

Light at the end of the tunnel: Integrative taxonom y delimits cryptic species in the Tetramorium caespitum complex (Hymenoptera: Formicidae)

It is highlighted that no single data was sufficient to disentangle the final species boundaries, which underlines the importance of integrating mu ltiple data sources.
The Ascent of the Abundant: How Mutational Networks Constrain Evolution

It is found that phenotype abundance—the number of genotypes producing a particular phenotype—varies in a predictable manner and critically influences evolutionary dynamics, which supports an “ascent of the abundant” hypothesis, in which evolution yields abundant phenotypes even when they are not the most fit.
Species diversity in neutral metacommunities: a network approach.
- E. Economo, T. Keitt
- Environmental ScienceEcology Letters
- 16 November 2007
This work advances the spatially explicit neutral model by representing the metacommunity as a network of smaller communities, and finds spatial structure can increase gamma-diversity relative to a well-mixed model, even when theta is held constant.
An updated checklist of the ants of India with their specific distributions in Indian states (Hymenoptera, Formicidae)

The present exhaustive listing of Indian ants will provide a holistic view about diversity and distribution and will also help to identify major undersampled areas where future sampling and taxonomic efforts should be directed.
The Global Ant Biodiversity Informatics (GABI) database: synthesizing data on the geographic distribution of ant species (Hymenoptera: Formicidae)

The first comprehensi ve global database of ant species distributions, the Global Ant B iodiversity Informatics (GABI) database, based on the compilatio n of 1.72 million records extracted from over 8811 publicatio ns and 25 existing databases is introduced.
Network isolation and local diversity in neutral metacommunities
- E. Economo, T. Keitt
- Environmental Science
- 1 August 2010
This work represents the metacommunity as a network of local communities, and uses network centrality measures to quantify the isolation of a local community, and examines how node position predicts variation in alpha diversity across a metacomunity to find that diversity increases with node centrality in the network.
Global hotspots and correlates of alien species richness across taxonomic groups
Analysis of eight taxonomic groups across 186 islands and 423 mainland regions reveals that those with the greatest gross domestic product per capita, human population density and area have the highest established alien species richness, with the strongest effects on islands.
Adaptive differences in plant physiology and ecosystem paradoxes: insights from metabolic scaling theory
- B. Enquist, A. Kerkhoff, T. Huxman, E. Economo
- Environmental Science
- 1 March 2007
The model provides a baseline for understanding how potentially adaptive variation in plant size and traits associated with metabolism and biomass production in differing biomes can influence whole-ecosystem processes and test one key implication of this model ‐ that directional and adaptive changes in metabolic and stoichiometric traits of autotrophs may mediate patterns of plant growth across broad temperature gradients.
