Better estimates of soil carbon from geographical data: a revised global approach
Duarte Guardia, Sandra; Peri, Pablo Luis; Amelung, Wulf; Sheil, Douglas; Laffan, Shawn W.; Borchard, Nils; Bird, Michael I.; Dieleman, Wouter; Pepper, David A.; Zutta, Brian; Jobbagy Gampel, Esteban Gabriel; Silva, Lucas C. R.; Bonser, Stephen P.; Berhongaray, Gonzalo; Piñeiro, Gervasio; Martinez, Maria Jose; Cowie, Annette L.; Ladd, Brenton (2018-05)Soils hold the largest pool of organic carbon (C) on Earth; yet, soil organic carbon (SOC) reservoirs are not well represented in climate change mitigation strategies because our database for ecosystems where human impacts ... -
Biophysical and socioeconomic factors influencing soil carbon stocks: a global assessment
Duarte Guardia, Sandra; Peri, Pablo Luis; Amelung, Wulf; Thomas, Evert; Borchard, Nils; Baldi, Germán; Cowie, Annette L.; Ladd, Brenton (Springer, 2020-07-24)Soil is the most important terrestrial carbon (C) reservoir but is greatly impacted by land use change (LUC). Previous analyses of LUC impacts on soil C have focused on biophysical variables, leaving aside the influence ... -
Biophysical and socioeconomic factors influencing soil carbon stocks: a global assessment. Appendix S1: Raw Dataset [Conjunto de datos]
Duarte Guardia, Sandra; Peri, Pablo Luis; Amelung, Wulf; Thomas, Evert; Borchard, Nils; Baldi, Germán; Cowie, Annette L.; Ladd, Brenton (Grupo de Investigación Forestal-Silvopastoril. Instituto Nacional de Tecnología Agropecuaria (INTA), EEA Santa Cruz; Universidad Nacional de la Patagonia Austral (UNPA); Centro Austral de Investigaciones Científicas (CADIC-CONICET)., 2020)Supplementary information of the: Duarte-Guardia, S., Peri, P., Amelung, W. et al.

Carbon (δ13C) and nitrogen (δ15N) stable isotope composition in plant and soil in Southern Patagonia’s native forests.
Peri, Pablo Luis; Ladd, Brenton; Pepper, David A.; Bonser, Stephen P.; Laffan, Shawn W.; Amelung, Wulf (Wiley, 2012-01)Stable isotope natural abundance measurements integrate across several biogeochemical processes in ecosystem N and C dynamics. Here, we report trends in natural isotope abundance (d13C and d15N in plant and soil) along a ... -
Carbon isotopic signatures of soil organic matter correlate with leaf area index across woody biomes
Ladd, Brenton; Peri, Pablo Luis; Pepper, David A.; Silva, Lucas C.R.; Sheil, Douglas; Bonser, Stephen P.; Laffan, Shawn W.; Amelung, Wulf; Ekblad, Alf; Eliasson, Peter; Bahamonde, Héctor Alejandro; Duarte Guardia, Sandra; Bird, Michael I. (Wiley, 2014-11)Leaf area index (LAI), a measure of canopy density, is a key variable for modelling and understanding primary productivity, and also water use and energy exchange in forest ecosystems. However, LAI varies considerably with ... -
Co-benefits of soil carbon protection for invertebrate conservation
Flores-Rios, Angelli; Thomas, Evert; Peri, Pablo Luis; Amelung, Wulf; Duarte Guardia, Sandra; Borchard, Nils; Lizárraga Travaglini, Alfonso; Vélez Azañero, Armando; Sheil, Douglas; Tscharntke, Teja; Steffan-Dewenter, Ingolf; Ladd, Brenton (Elsevier, 2020-12)The global decline in invertebrate diversity requires urgent conservation interventions. However, identifying priority conservation areas for invertebrates remains a significant challenge. We hypothesized that aligning the ... -
Estimates of soil carbon concentration in tropical and temperate forest and woodland from available GIS data on three continents
Ladd, Brenton; Laffan, Shawn W.; Amelung, Wulf; Peri, Pablo Luis; Silva, Lucas C. R.; Gervassi, Pina; Bonser, Stephen P.; Sheil, Douglas; Navall, Jorge Marcelo (2013-04)Aim: Concern about climate change, with the subsequent emergence of carbonmarkets and policy initiatives such as REDD (reducing carbon emissions bydecreasing deforestation and forest degradation), have focused attention ... -
Precipitation is the key determinant of topsoil δ15N values in southern Patagonia’s semiarid rangelands
Peri, Pablo Luis; Duarte Guardia, Sandra; Amelung, Wulf; Ladd, Brenton (American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2022-02-11)Nitrogen (N) cycling in rangeland soils could potentially be controlled by water supply, stocking rates, or a range of other variables, such as ecosystem N stocks. To gauge the relative importance and elucidate possible ...
