Microbiology is the basis of sustainable agriculture: an opinion (2011, background): “The balance between symbiotrophic and combined N nutrition may be improved by a rapid removal of N-compounds from the actively N2-fixing symbioses, as has been suggested for tropical forest ecosystems (Hedin et al., 2009).”
Biological nitrogen fixation by alternative nitrogenases in terrestrial ecosystems: a review (2020, background): “Overall, studies that performed both ARA and (15)N incubations on the same samples in the field (Bellenger et al. 2014; Hedin et al. 2009; Vile et al. 2014) suggest that variations in the R ratio due to nitrogenase isozyme diversity have been underestimated.”
Multi-element regulation of the tropical forest carbon cycle (2011, background): “Hedin et al. (2009) also argued that spatial and temporal differences in N and P availability can contribute to shifting patterns of nutrient limitation within different portions of a single ecosystem.”
Global assessment of limitation to symbiotic nitrogen fixation by phosphorus availability in terrestrial ecosystems using a meta‐analysis approach (2013, background): “Because N is not present in the original Earth’s crust, one major challenge for organisms is to access a sufficient supply of N [e.g., Hedin et al., 2009].”
Tropical tree seedling growth responses to nitrogen, phosphorus and potassium addition (2012, background): “We expected a growth response to P addition because P is widely hypothesized to be limiting in lowland tropical forests (Vitousek 1984; Hedin et al. 2009).”
Patterns and Mechanisms of Nutrient Resorption in Plants (2015, background): “Between tropical and temperate forests, N limitation is comparable (LeBauer and Treseder, 2008); however, the relatively higher abundance of N fixers in the tropics than temperate forests has made this limitation more complex (Hedin et al., 2009).”
Nitrogen fixation in legumes and actinorhizal plants in natural ecosystems: values obtained using 15N natural abundance (2011, background): “Also, there was evidence that growth of N2-fixing Acacia spp. was limited by grass competition for P. Hedin et al. (2009) argued, on the basis of theory and available data, that N availability to plants is not homogeneously distributed within tropical forest ecosystems, and 138 M. Andrews et…”
Evolutionary Legacy Effects on Ecosystems: Biogeographic Origins, Plant Traits, and Implications for Management in the Era of Global Change (2016, background): “These lineages would include species from lower latitudes that have high phosphorus use efficiency (Hedin et al. 2009), low nitrogen use efficiency (Kerkhoff et al. 2006), and high nitrogen:phosphorus ratios (McGroddy et al. 2004, Reich & Oleksyn 2004).”
Priming and microbial nutrient limitation in lowland tropical forest soils of contrasting fertility (2012, background): “Priming resulting from nutrient limitation in tropical forest soils, which can contain abundant organic N (Hedin et al. 2005) and organic P (Turner and Engelbrecht 2011; Dieter et al. 2010), would have large consequences for the tropical forest C balance under elevated CO2 by increasing the pool…”
Nitrogen and phosphorus interact to control tropical symbiotic N2 fixation: a test in Inga punctata (2013, background): “…of Ecology 2013, 101, 1400–1408 doi: 10.1111/1365-2745.12138 fixation’) as these fixers are abundant in many tropical forests, have access to substantial reducing power (light) and can catalyse high rates of ecosystem N2 input (Hedin et al. 2009; Sprent 2009; Barron, Purves & Hedin 2011).”
Relationships among phosphorus, molybdenum and free-living nitrogen fixation in tropical rain forests: results from observational and experimental analyses (2013, background): “As a result, identifying the factors that control this important process is critical for predicting a suite of ecosystem processes—including net primary productivity (NPP), decomposition and community composition—both now and into the future (Vitousek and Howarth 1991; Vitousek et al. 2002; Hungate ”
