The Nitrogen Paradox in Tropical Forest Ecosystems (2009, background): “This condition is characteristic of unpolluted temperate forests that are subject to strong N limitation (e.g., Hedin et al. 1995, 2003; Perakis & Hedin 2002; McGroddy et al. 2008).”
Biological nitrogen fixation: rates, patterns and ecological controls in terrestrial ecosystems (2013, background): “However, we suspect that pre-industrial systems probably lost a smaller fraction of N to denitrification along flowpaths, in large part because nitrate was a smaller fraction of total losses [30]; for this reason, our BNF estimate may err on the high side.”
Epiphyte diversity and biomass loads of canopy emergent trees in Chilean temperate rain forests: A neglected functional component (2010, background): “Chilean coastal rain forest, characterized by unpolluted, preindustrial atmospheric conditions (Hedin et al., 1995; Perakis and Hedin, 2002), and low pre-historic and current human impacts (Gutiérrez et al.”
Nitrogen addition stimulates forest litter decomposition and disrupts species interactions in Patagonia, Argentina (2011, background): “…into the biogeochemical conditions that constrain ecosystem functioning before human domination of natural systems and provide an opportunity to evaluate biogeochemical theories that have been developed in areas subject to strong human influences (e.g. Hedin et al., 1995; Perakis & Hedin, 2002).”
Spatial patterns of leaf nutrient traits of the plants in the Loess Plateau of China (2007, background): “In contrast, temperate and boreal forests tend to be highly N deficient due to a relative lack of symbiotic N fixer (Cleveland et al. 1999), significant N losses in dissolved organic N (Hedin et al. 1995; Perakis and Hedin 2002 ), or episodic N losses associated with fires and other local disturban”
The Nitrogen Cascade (2003, background): “In undisturbed areas in the temperate zone, the major terrestrial flux of Nr into surface waters may be organic Nr in the form of detritus or dissolved organic matter washed into lakes and streams (Lewis 2002, Perakis and Hedin 2002).”
Mechanisms of plant species impacts on ecosystem nitrogen cycling (2002, background): “Recent evidence shows that nitrogen losses from unpolluted, undisturbed forest are much lower and mainly in the form of dissolved organic compounds (Perakis & Hedin 2002).”
Dissolved organic nitrogen: a dynamic participant in aquatic ecosystems (2003, background): “A study by Perakis & Hedin (2002) found that 70% of the TDN in streams and rivers of temperate South American forest regions that were pristine and free of human intervention consisted of DON.”
