Journal ArticleDOI
Global assessment of nitrogen deposition effects on terrestrial plant diversity: a synthesis.
Roland Bobbink,Kevin Hicks,James N. Galloway,Till Spranger,Rob Alkemade,Mike Ashmore,Mercedes M. C. Bustamante,Steve Cinderby,Eric A. Davidson,Frank Dentener,Bridget A. Emmett,Jan Willem Erisman,Mark E. Fenn,Frank S. Gilliam,Annika Nordin,Linda H. Pardo,W. de Vries +16 more
TL;DR: Ecosystems thought of as not N limited, such as tropical and subtropical systems, may be more vulnerable in the regeneration phase, in situations where heterogeneity in N availability is reduced by atmospheric N deposition, on sandy soils, or in montane areas.
Journal ArticleDOI
Nitrogen excess in North American ecosystems: Predisposing factors, ecosystem responses, and management strategies
Mark E. Fenn,Mark A. Poth,John D. Aber,Jill S. Baron,Bernard T. Bormann,Dale W. Johnson,A. Dennis Lemly,Steven G. McNulty,Douglas F. Ryan,Robert Stottlemyer +9 more
TL;DR: In this article, the authors identified forested areas that exhibit symptoms of N excess, analogous to overfertilization of arable land, and showed that some forests receiving chronic N inputs may decline in productivity and experience greate...
Journal ArticleDOI
Ecological Effects of Nitrogen Deposition in the Western United States
Mark E. Fenn,Jill S. Baron,Edith B. Allen,Heather M. Rueth,Koren R. Nydick,Linda H. Geiser,William D. Bowman,James O. Sickman,James O. Sickman,Thomas Meixner,Dale W. Johnson,Peter Neitlich +11 more
TL;DR: In the western United States vast acreages of land are exposed to low levels of atmospheric nitrogen (N) deposition, with interspersed hotspots of elevated N deposition downwind of large, expanding metropolitan centers or large agricultural operations.
Journal ArticleDOI
Nitrogen Emissions, Deposition, and Monitoring in the Western United States
Mark E. Fenn,Richard Haeuber,Gail S. Tonnesen,Jill S. Baron,Susanne Grossman-Clarke,Diane Hope,Daniel A. Jaffe,S. Copeland,Linda H. Geiser,Heather M. Rueth,James O. Sickman +10 more
TL;DR: Nitrogen deposition in the western United States ranges from 1 to 4 kilograms (kg) per hectare (ha) per year over much of the region to as high as 30 to 90 kg per ha per year downwind of major urban and agricultural areas.
BookDOI
Microbial ecology of leaves
TL;DR: A number of critical reviews by internationally recognized experts on the microbial ecology of leaves are presented in this paper, including methods of assessment of microbial populations on leaf surfaces, leaves as reservoirs of ice nucleation phenomenon, and leaves as microbial habitats in both aquatic and terrestrial environments.
