Drought-exposed leaves adversely affect soil nutrients, study shows
ScienceDaily (Apr. 5, 2011) — Chemical changes in tree leaves subjected to warmer, drier conditions that could result from climate change may reduce the availability of soil nutrients, according to a Purdue University study.Jeff Dukes, an associate professor of forestry and natural resources, found that red maple leaves accumulate about twice as much tannin when … Continue reading
Adding nutrients to oceans could enhance transfer of carbon dioxide from atmosphere to deep ocean
ScienceDaily (June 30, 2010) Adding nutrients to the sea could decrease viral infection rates among phytoplankton and enhance the efficiency of the biological pump, a means by which carbon is transferred from the atmosphere to the deep ocean, according to a new mathematical modelling study. The findings, published in the Journal of Theoretical Biology, … Continue reading
Source of essential nutrients for mid-ocean algae discovered
ScienceDaily (June 23, 2010) For almost three decades, oceanographers have been puzzled by the ability of microscopic algae to grow in mid-ocean areas where there is very little nitrate, an essential algal nutrient. In a study appearing in Nature, MBARI chemical oceanographer Ken Johnson, along with coauthors Stephen Riser at the University of Washington … Continue reading
