Journal ArticleDOI
Variation in photoreactivity of iron hydroxides taken from an acidic mountain stream
TL;DR: In this paper, the variation in reactivity of iron hydroxides taken from a stream receiving acid mine drainage (AMD) was studied using laboratory and in-stream measurements, and the importance of ligand coordination to the enhancement of photoreduction in natural waters was further demonstrated in experiments using two types of fulvic acids.
Journal ArticleDOI
Hydrodynamic control of benthic mats of Didymosphenia geminata at the reach scale
TL;DR: In this article, site-specific geomorphic controls on Didymosphenia geminata were evaluated for the habitat structure and functioning of stream ecosystems, and the results showed that the control of D. gemina blooms caused by the stalk-forming diatom did not significantly affect the habitat of streams.
Journal ArticleDOI
The Mcmurdo Dry Valleys Long‐Term Ecological Rsearch Program: New understanding of the biogeochemistry of the Dry Valley Lakes: A review 1
W. Berry Lyons,Kathleen A. Welch,John C. Priscu,Johanna Labourn‐Parry,Daryl L. Moorhead,Diane M. McKnight,Peter T. Doran,Martyn Tranter +7 more
TL;DR: A review of recent findings on the biogeochemistry and food chain dynamics of these lakes is summarized within this article, and the importance of collecting long-term data is imperative if an understanding of how sensitive systems respond to climate change is to be gained.
Journal ArticleDOI
Response of the Phytoplankton Community in an Alpine Lake to Drought Conditions: Colorado Rocky Mountain Front Range, U.S.A
Colleen M. Flanagan,Colleen M. Flanagan,Diane M. McKnight,Daniel Liptzin,Mark W. Williams,Matthew P. Miller +5 more
TL;DR: In this article, the authors examined the summer phytoplankton community in Green Lake 4 for a 6-year period that included the summer of 2002 and found that the response of the phyto-ankton communities to the extreme drought was most strongly correlated with water quality changes that occurred, rather than temperature and hydraulic residence time.
Journal ArticleDOI
Biogeochemical processes controlling midday ferrous iron maxima in stream waters affected by acid rock drainage
Diane M. McKnight,Sabre M. Duren +1 more
TL;DR: In this paper, the potential for Fe(II)-oxidizing reactions, including the Fenton and microbial oxidation reactions, to constrain the mid-day Fe (II) maxima concentration in acid rock drainage (ARD) streams has been assessed.
