    • 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 ...

    • 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 ...

    • 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 ...
