The importance of individuals: intraspecific diversity of mycorrhizal plants and fungi in ecosystemsDavid Johnson
Institute of Biological and Environmental Sciences, University of Aberdeen, Aberdeen, UK
New Phytol 194:614-28. 2012....
Drought alters carbon fluxes in alpine snowbed ecosystems through contrasting impacts on graminoids and forbsDavid Johnson
Institute of Biological and Environmental Sciences, University of Aberdeen, Aberdeen, UK
New Phytol 190:740-9. 2011..Our data show that drought events can have significant impacts on ecosystem carbon fluxes, and that the principal mechanism behind this is probably changes in the relative abundance of forbs and grasses...
Direct and indirect effects of ammonia, ammonium and nitrate on phosphatase activity and carbon fluxes from decomposing litter in peatlandDavid Johnson
Institute of Biological and Environmental Sciences, University of Aberdeen AB24 3UU, UK
Environ Pollut 158:3157-63. 2010..Our results show that the collective impacts on peatlands of the three principal forms of nitrogen in atmospheric deposition are a result of differential effects and mechanisms on individual components...
Resolving uncertainty in the carbon economy of mycorrhizal fungiDavid Johnson
Institute of Biological and Environmental Sciences, University of Aberdeen, Aberdeen AB24 3UU, UK
New Phytol 180:3-5. 2008
Plant community composition, not diversity, regulates soil respiration in grasslandsDavid Johnson
Institute of Biological and Environmental Sciences, University of Aberdeen, Aberdeen, UK
Biol Lett 4:345-8. 2008..This finding is important, because it suggests that loss of particular species will have the greatest impact on soil respiration, rather than changes in biodiversity per se...
Soil invertebrates disrupt carbon flow through fungal networksDavid Johnson
School of Biological Sciences, University of Aberdeen, Aberdeen AB24 3UU, UK
Science 309:1047. 2005..Our findings emphasize the importance of multitrophic interactions in regulating respiration of recent plant photosynthate from soil...
How do plants regulate the function, community structure, and diversity of mycorrhizal fungi?David Johnson
School of Biological Sciences, Cruickshank Building, University of Aberdeen, Aberdeen AB31 5TR, UK
J Exp Bot 56:1751-60. 2005..It concludes by highlighting some of the new methodological advances that promise to unravel the linkages between mycorrhizal diversity and their function in situ...
Intraspecific diversity regulates fungal productivity and respirationAnna Wilkinson
Institute of Biological and Environmental Sciences, University of Aberdeen, Aberdeen, United Kingdom
PLoS ONE 5:e12604. 2010....
Nitrous oxide production by the ectomycorrhizal fungi Paxillus involutus and Tylospora fibrillosaMiranda T Prendergast-Miller
Institute of Biological and Environmental Sciences, University of Aberdeen, Aberdeen, UK
FEMS Microbiol Lett 316:31-5. 2011..Given that these species are abundant in many forest soils, the strength and regulation of fungal N(2)O production should now be verified in situ...
New insights into the mycorrhizal Rhizoscyphus ericae aggregate: spatial structure and co-colonization of ectomycorrhizal and ericoid rootsGwen Aelle Grelet
Institute of Biological and Environmental Sciences, University of Aberdeen, Aberdeen, AB24 3UU, UK
New Phytol 188:210-22. 2010..Our data also suggest significant genotypic overlap between widely separated populations of this ubiquitous root-associated fungus...
Interactions among fungal community structure, litter decomposition and depth of water table in a cutover peatlandClare J Trinder
Institute of Biological and Environmental Sciences, University of Aberdeen, Aberdeen, UK
FEMS Microbiol Ecol 64:433-48. 2008..The results have implications for the ways restoration programmes and global climate change may impact upon nutrient cycling in cutover peatlands...

Assessment of the environmental fate and effects of ivermectin in aquatic mesocosmsHans Sanderson
National Environmental Research Institute, Department of Policy Analysis, Aarhus University, Frederiksborgvej 399, Post Box 358, DK 4000 Roskilde, Denmark
Aquat Toxicol 85:229-40. 2007..This is the first study to demonstrate the potential environmental risk of ivermectin at or below the predicted environmental concentration using a standardized test methodology (mesocosm) with minimal extrapolation uncertainty...
Cardiorespiratory fitness is related to physical inactivity, metabolic risk factors, and atherosclerotic burden in glucose-intolerant renal transplant recipientsKirsten Armstrong
Department of Nephrology, University of Queensland at Princess Alexandra Hospital, Brisbane, Queensland, Australia
Clin J Am Soc Nephrol 1:1275-83. 2006..63; P = 0.04). Reduced CF is associated with physical inactivity, MS, and atherosclerotic burden in glucose-intolerant RTR. Further studies should address whether increasing exercise and modifying MS risk factors improve CF in RTR...
