The terrestrial biosphere sequesters up to a
third of annual anthropogenic carbon dioxide emissions,
offsetting a substantial portion of greenhouse
gas forcing of the climate system. Although a number
of factors are responsible for this terrestrial carbon
sink, atmospheric nitrogen deposition contributes by
enhancing tree productivity and promoting carbon
storage...

Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species’ threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that...

Background: We present a model for reporting accelerometer paradata (process-related data produced from survey administration) collected in the International Study of Childhood Obesity Lifestyle and the Environment (ISCOLE), a multi-national investigation of >7000 children (averaging 10.5 years of age) sampled from 12 different developed and developing countries and five continents....

BACKGROUND: We compared 24-hour waist-worn accelerometer wear time characteristics of 9-11 year old children
in the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE) to similarly aged U.S. children
providing waking-hours waist-worn accelerometer data in the 2003-2006 National Health and Nutrition Examination
Survey (NHANES).
METHODS: Valid cases were...

The 1994 Northwest Forest Plan (NWFP) shifted federal lands management from a focus on timber production to ecosystem management and biodiversity conservation. The plan established a network of conservation reserves and an ecosystem management strategy on ~10 million hectares from northern California to Washington State, USA, within the range of...

Convergent evolution is common throughout the tree of life, but the molecular mechanisms
causing similar phenotypes to appear repeatedly are obscure. Yeasts have arisen in multiple
fungal clades, but the genetic causes and consequences of their evolutionary origins are
unknown. Here we show that the potential to develop yeast forms...

Convergent evolution is common throughout the tree of life, but
Non-structural carbohydrates (NSC) in plant tissue are frequently quantified to make inferences about plant responses to environmental conditions. Laboratories publishing estimates of NSC of woody plants use many different methods to evaluate NSC. We asked whether NSC estimates in the recent literature could be quantitatively compared among studies. We also...
