Altered gene expression and DNA damage in peripheral blood cells from Friedreich's ataxia patients: cellular model of pathology.
(PLoS Genet, 2010-01-15)The neurodegenerative disease Friedreich's ataxia (FRDA) is the most common autosomal-recessively inherited ataxia and is caused by a GAA triplet repeat expansion in the first intron of the frataxin gene. In this disease, ... -
An assessment of high carbon stock and high conservation value approaches to sustainable oil palm cultivation in Gabon
(Environmental Research Letters, 2017-01-01)© 2017 IOP Publishing Ltd. Industrial-scale oil palm cultivation is rapidly expanding in Gabon, where it has the potential to drive economic growth, but also threatens forest, biodiversity and carbon resources. The Gabonese ... -
An evaluation of the statistics of rainfall extremes in rain gauge observations, and satellite-based and reanalysis products using universal multifractals
(Journal of Hydrometeorology, 2010-04-01)Confidence in the estimation of variations in the frequency of extreme events, and specifically extreme precipitation, in response to climate variability and change is key to the development of adaptation strategies. One ... -
Analysis of soil carbon transit times and age distributions using network theories
(Journal of Geophysical Research: Biogeosciences, 2009-01-01)The long-term soil carbon dynamics may be approximated by networks of linear compartments, permitting theoretical analysis of transit time (i.e., the total time spent by a molecule in the system) and age (the time elapsed ... -
Antagonistic Growth Effects of Mercury and Selenium in Caenorhabditis elegans Are Chemical-Species-Dependent and Do Not Depend on Internal Hg/Se Ratios.
(Environ Sci Technol, 2016-03-15)The relationship between mercury (Hg) and selenium (Se) toxicity is complex, with coexposure reported to reduce, increase, and have no effect on toxicity. Different interactions may be related to chemical compound, but this ... -
Assessing variability and long-term trends in burned area by merging multiple satellite fire products
(Biogeosciences, 2010-04-12)Long term, high quality estimates of burned area are needed for improving both prognostic and diagnostic fire emissions models and for assessing feedbacks between fire and the climate system. We developed global, monthly ... -

(Oceanography, 2013-09-01)The Moorea Coral Reef Long Term Ecological Research project funded by the US National Science Foundation includes multidisciplinary studies of physical processes driving ecological dynamics across the fringing reef, back ... -
Boom and bust carbon-nitrogen dynamics during reforestation
(Ecological Modelling, 2017-09-24)© 2017 Elsevier B.V. Legacies of historical land use strongly shape contemporary ecosystem dynamics. In old-field secondary forests, tree growth embodies a legacy of soil changes affected by previous cultivation. Three patterns ... -
Boron and strontium isotopic characterization of coal combustion residuals: validation of new environmental tracers.
(Environ Sci Technol, 2014-12-16)In the U.S., coal fired power plants produce over 136 million tons of coal combustion residuals (CCRs) annually. CCRs are enriched in toxic elements, and their leachates can have significant impacts on water quality. Here ... -

Chemical composition and aerosol size distribution of the middle mountain range in the Nepal Himalayas during the 2009 pre-monsoon season
(Atmospheric Chemistry and Physics, 2010-12-15)Aerosol particle number size distribution and chemical composition were measured at two low altitude sites, one urban and one relatively pristine valley, in Central Nepal during the 2009 pre-monsoon season (May-June). This ... -
Chronic microfiber exposure in adult Japanese medaka (Oryzias latipes).
(PloS one, 2020-01)Microplastic fibers (MFs) pollute aquatic habitats globally via sewage release, stormwater runoff, or atmospheric deposition. Of the synthetic MFs, polyester (PES) and polypropylene (PP) are the most common. Field studies ... -
Climate change, water resources, and the politics of adaptation in the Middle East and North Africa
(Climatic Change, 2011-02-01)Through an examination of global climate change models combined with hydrological data on deteriorating water quality in the Middle East and North Africa (MENA), we elucidate the ways in which the MENA countries are vulnerable ... -
