Nitrogen limitation of net primary productivity in terrestrial ecosystems is globally distributed. (2008, background): “Presently, anthropogenic N inputs average 1 g N m 2 yr 1 over terrestrial ecosystems and could level off at 4–6 g N m 2 yr 1 during the next century (Prather et al. 2001, Galloway and Cowling 2002, Lamarque et al. 2005).”
Looking forward through the past: identification of 50 priority research questions in palaeoecology (2014, neutral): “A key question for global change ecologists involves understanding how these two cycles will covary in future, particularly in the context of increasing carbon dioxide concentrations and excess nitrogen deposition (Galloway & Cowling 2002) [Q27].”
Response of soil microbial biomass and community composition to chronic nitrogen additions at Harvard forest (2004, background): “Humans have dramatically altered the supply of nutrients to terrestrial ecosystems (Vitousek et al., 1997; Galloway and Cowling, 2002), yet few studies have examined the widespread effects of increased nutrient supply on microbial biomass, function and community composition.”
The mycorrhizal-associated nutrient economy: a new framework for predicting carbon-nutrient couplings in temperate forests. (2013, background): “Temperate forests receive some of the highest rates of N deposition on earth (Holland et al., 1999; Galloway & Cowling, 2002; Elliott et al., 2007).”
Terrestrial phosphorus limitation: mechanisms, implications, and nitrogen-phosphorus interactions. (2010, background): “Human-enhanced N deposition now is concentrated in Europe, central and eastern North 340 America, east Asia, and peri-urban areas elsewhere (Galloway and Cowling 2002).”
Large-scale changes in the abundance of common higher plant species across Britain between 1978, 1990 and 1998 as a consequence of human activity: Tests of hypothesised changes in trait representation (2005, background): “Over the past 200 years however, the drive for greater global production has seen technological advances that have increased and accelerated the amounts of nitrogen and phosphorus contributed by human activity (Galloway and Cowling, 2002).”
Ecological Predictors of Extinction Risk in the Flora of Lowland England, UK (2006, background): “In Europe, N deposition and accumulation has increased dramatically over recent decades (e.g. NEGTAP 2001; Peñuelas and Filella 2001) causing significant changes to the species composition of a wide range of terrestrial and aquatic ecosystems, particularly grasslands and heathlands associated with ”
The role of the oceans in climate (2003, background): “This pattern of distribution is expected to change substantially in the future, with increased industrial activity in Asia in particular (Galloway and Cowling, 2002).”
Integrating microbial ecology into ecosystem models: challenges and priorities (2012, background): “…in biogeochemical models Nitrogen fertilization, cultivation of N-fixing crops, and fossil fuel burning by humans have approximately doubled the rate at which reactive (i.e., bioavailable) N is deposited on ecosystems globally (Galloway and Cowling 2002; Holland et al. 2005; Vitousek et al. 1997).”
