    • 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 ...

    • Climate change-related growth improvements in a wide niche-breadth tree species across contrasting environments 

      Fajardo, Alex; Gazol, Antonio; Moreno Meynard, Paulo; Mayr, Christoph; Martínez Pastur, Guillermo José; Peri, Pablo Luis; Camarero, Julio (Oxford University Press, 2023-05-09)
      Background and Aims The vulnerability and responsiveness of forests to drought are immensely variable across biomes. Intraspecific tree responses to drought in species with wide niche breadths that grow across contrasting ...

    • Convergence of soil nitrogen isotopes across global climate gradients 

      Craine, Joseph M.; Elmore, Andrew J.; Wang, Lixing; Augusto, Laurent; Baisden, Troy; Brookshire, E.N.J.; Cramer, Michael D.; Hasselquist, Niles; Hobbie, Erik A.; Kahmen, Ansgar; Kaba, Keisuke; Kranabetter, M.; Mack, M.; Marin-Spiotta, E.; Mayor, J.R.; McLauchlan, K.K.; Michelsen, A.; Nardoto, G.B.; Oliveira, R.S.; Perakis, S.S.; Peri, Pablo Luis; Quesada, C.; Richter, A.; Schipper, L.A.; Stevenson, B.A.; Turner, B.L.; Viani, R.A.G.; Wanek, W.; Zeller, B. (2015-02-06)
      Quantifying global patterns of terrestrial nitrogen (N) cycling is central to predicting future patterns of primary productivity, carbon sequestration, nutrient fluxes to aquatic systems, and climate forcing. With limited ...

    • Isotopic evidence for oligotrophication of terrestrial ecosystems 

      Craine, Joseph M.; Elmore, Andrew J.; Wang, Lixing; Aranibar, Julieta; Bauters, Marijn; Boeckx, Pascal; Crowley, Brooke E.; Dawes, Melissa A.; Delzon, Sylvain; Fajardo, Alex; Fang, Yunting; Fujiyoshi, Lei; Gray, Alan; Guerrieri, Rossella; Gundale, Michel J.; Hawke, David J.; Hietz, Peter; Jonard, Mathieu; Kearsley, Elizabeth; Kenzo, Tanaka; Makarov, Mikhail; Marañón Jiménez, Sara; McGlynn, Terrence P.; McNeil, Brenden E.; Mosher, Stella G.; Nelson, David M.; Peri, Pablo Luis; Roggy, Jean Christophe; Sanders-DeMott, Rebecca; Song, Minghua; Szpak, Paul; Templer, Pamela H.; Colff, Dewidine van der; Werner, Christiane; Xu, Xingliang; Yang, Yang; Yu, Guirui; Zmudczyńska-Skarbek, Katarzyna (Springer Nature, 2018)
      Human societies depend on an Earth system that operates within a constrained range of nutrient availability, yet the recent trajectory of terrestrial nitrogen (N) availability is uncertain. Examining patterns of foliar N ...

    • Reply to: Data do not support large-scale oligotrophication of terrestrial ecosystems. 

      Craine,  Joseph M.; Elmore, Andrew J.; Wang, Lixin  ; Boeckx, Pascal; Delzon, Sylvain; Fang, Yunting  ; Gray, Alan  ; Guerrieri , Rossella; Gundale, Michael J.; Hietz , Peter; Nelson, David M.  ; Peri, Pablo Luis; Templer, Pamela H; Werner, Christiane (Springer Nature, 2019-07-22)
      Hiltbrunner et al. apply a reductionist approach to argue that the evidence for widespread terrestrial oligotrophication2 should be replaced with a two-factor explanation (growth dilution and depositional signatures) that ...
