Nitrogen fluxes from large watershed to coastal ecosystems controlled by net anthropogenic nitrogen inputs and climate
Howarth, R. W.; Swaney, D. P.; Billen, G.; Garnier, J.; Hong, B.; Humborg, C.; Johnes, P.; Morth, C.; Marino, R. M. (Wiley, 2011-07-15)The flux of nitrogen (N) to coastal marine ecosystems is strongly correlated with the net anthropogenic nitrogen inputs (NANI) to the landscape across 154 watersheds, ranging in size from 16 km 2 to 279 000 km 2, in the ... -
A bridge to nowhere: Methane emissions and the greenhouse gas footprint of natural gas
Howarth, R. W. (Wiley, 2014-05-14)In April 2011, we published the first peer-reviewed analysis of the greenhouse gas footprint (GHG) of shale gas, concluding that the climate impact of shale gas may be worse than that of other fossil fuels such as coal and ... -
Linking environmental nutrient enrichment and disease emergence in humans and wildlife
Johnson, P. T.; Townsend, A. R.; Cleveland, C. C.; Glibert, P. M.; Howarth, R. W.; McKenzie, V. J.; Rejmankova, E.; Ward, M. H. (Wiley, 2010-01-10)Worldwide increases in human and wildlife diseases have challenged ecologists to understand how large-scale environmental changes affect host-parasite interactions. One of the most profound changes to Earth's ecosystems ... -
Inputs of sediment and carbon to an estuarine ecosystem: Influence of land use
Howarth, R. W.; Fruci, J.R.; Sherman, D.M. (Wiley, 1991-02-01)Estuaries and coastal marine ecosystems receive large inputs of nutrients, organic carbon, and sediments from non—point—source runoff from terrestrial ecosystems. In the tidal, freshwater Hudson River estuary, such inputs ... -
Changes in anthropogenic nitrogen and phosphorus inputs to the St. Lawrence Basin over 110 years: Impacts on riverine export
Goyette, J.O.; Bennett, E.; Howarth, R. W.; Maranger, R. (Wiley, 2016-07-06)Human activities have increased the flow of nitrogen (N) and phosphorus (P) over much of the Earth, leading to increased agricultural production, but also the degradation of air, soil, and water quality. Here we quantify ... -
The role of technology and policy in mitigating regional nitrogen pollution
Gu, Baojing; Zhu, Yimei; Chang, Jie; Peng, Chanhui; Liu, Dong; Min, Yong; Luo, Weidong; Howarth, R. W.; Ge, Y. (Institute of Physics Publishing, 2011-03-01)Human activity greatly influences nitrogen (N) pollution in urbanized and adjacent areas. We comprehensively studied the N cycling in an urban-rural complex system, the Greater Hangzhou Area (GHA) in southeastern China. ... -
Effects of varying salinity on phytoplankton growth in a low-salinity coastal pond under two nutrient conditions
Barron, S.; Weber, C. F.; Marino, R. M.; Davidson, E. A.; Tomasky, G.; Howarth, R. W. (University of Chicago Press, 2002-10)Human activities have clearly caused dramatic alterations of the terrestrial nitrogen cycle, and analyses of the extent and effects of such changes are now common in the scientific literature. However, any attempt to ... -
Estimating net anthropogenic nitrogen inputs (NANI) in the Lake Dianchi basin of China
Gao, W.; Howarth, R. W.; Hong, B.; Swaney, D. P.; Guo, H.C. (Copernicus, 2014-08-28)Net anthropogenic nitrogen inputs (NANI) with components of atmospheric N deposition, synthetic N fertilizer, agricultural N fixation and N in net food and feed imports from 15 catchments in the Lake Dianchi basin were ... -
Coastal marine eutrophication: Control of both nitrogen and phosphorus is necessary
Howarth, R. W.; Paerl, H. (PNAS, 2008-12-09)Human activities have clearly caused dramatic alterations of the terrestrial nitrogen cycle, and analyses of the extent and effects of such changes are now common in the scientific literature. However, any attempt to ... -
Global patterns of terrestrial biological nitrogen (N2) fixation in natural systems
Cleveland, C. C.; Townsend, A. R.; Schimel, D. S.; Fisher, H.; Howarth, R. W.; Hedin, L. O.; Perakis, S. S.; Latty, E. F.; von Fischer, J. C.; Elseroad, A.; Wasson, M. F. (Wiley, 1999-06-01)Human activities have clearly caused dramatic alterations of the terrestrial nitrogen cycle, and analyses of the extent and effects of such changes are now common in the scientific literature. However, any attempt to ...
