    • Foliar N⁄ P ratio and nutrient limitation to vegetation growth on Keerqin sandy grassland of North-east China. 

      Li, L.-J.; Zeng, D.-H.; Yu, Z.-Y.; Fan, Z.-P.; Mao, R.; Peri, Pablo Luis (Wiley, 2011-02-01)
      To examine whether the critical leaf N ⁄ P ratios (of 14, 16) are valid to test nutrient limitation in the context of semi-arid sandy grasslands, an experiment was conducted on a Keerqin sandy grassland in North-east China ...

    • General destabilizing effects of eutrophication on grassland productivity at multiple spatial scales 

      Hautier, Yann; Zhang, Pengfei; Loreau, Michel; Wilcox, Kevin R.; Seabloom, Eric William; Borer, Elizabeth T.; Byrnes, Jarrett E.K.; Koerner, Sally E.; Komatsu, Kimberly J.; Lefcheck, Jonathan S.; Hector, Andy; Adler, Peter B.; Alberti, Juan; Arnillas, Carlos Alberto; Bakker, Jonathan D.; Brudvig, Lars A.; Bugalho, Miguel N.; Cadotte, Marc.; Caldeira, Maria C.; Carroll, Oliver; Crawley, Mick; Collins, Scott L.; Daleo, Pedro; Dee, Laura E.; Eisenhauer, Nico; Eskelinen, Anu; Fay, Philip A.; Gilbert, Benjamin; Hansar, Amandine; Isbell, Forest; Knops, Johannes M.H.; MacDougall, Andrew S.; McCulley, Rebecca L.; Moore, Joslin L.; Morgan, John W.; Mori, Akira S.; Peri, Pablo Luis; Pos, Edwin; Power, Sally A.; Price, Jodi N.; Reich, Peter B.; Risch, Anita C.; Roscher, Christiane; Sankaran, Mahesh; Schütz, Martin; Smith, Melinda D.; Stevens, Carly J.; Tognetti, Pedro Maximiliano; Virtanen, Risto; Wardle, Glenda M.; Wilfahrt, Peter A.; Wang, Shaopeng (Springer Nature, 2020-10-23)
      Eutrophication is a widespread environmental change that usually reduces the stabilizing effect of plant diversity on productivity in local communities. Whether this effect is scale dependent remains to be elucidated. Here, ...

    • Litter decomposition and nutrients dynamics in Nothofagus antarctica forests under silvopastoral use in Southern Patagonia. 

      Bahamonde, Héctor Alejandro; Peri, Pablo Luis; Alvarez, Roberto; Barneix, Atilio Jose; Moretto, Alicia Susana; Martínez Pastur, Guillermo José (Springer, 2012-01-24)
      The role of environmental variables on litter decomposition and its nutrient release in Nothofagus antarctica forest in Patagonia is poorly understood. Moreover, in these forests under silvopastoral use there are few ...

    • Mineral fertilization impacts microbial activity and endophytic fungi but not microbial biomass in semiarid grasslands 

      Toledo, Santiago; Gargaglione, Veronica Beatriz; Peri, Pablo Luis (Elsevier, 2024-01)
      Applications of mineral fertilizer to grasslands have become more frequent in recent decades to increase forage production. However, the impacts of mineral fertilizer on the soil microbiome is poorly understood in cold ...

    • Nitrogen but not phosphorus addition affects symbiotic N2 fixation by legumes in natural and semi‑natural grasslands located on four continents 

      Vázquez, Eduardo; Schleuss, Per‑Marten; Borer, Elizabeth T.; Bugalho, Miguel N.; Caldeira, Maria. C.; Eisenhauer, Nico; Eskelinen, Anu; Fay, Philip A.; Haider, Sylvia; Jentsch, Anke; Kirkman, Kevin P.; McCulley, Rebecca L.; Peri, Pablo Luis; Price, Jodi; Richards, Anna E.; Risch, Anita C.; Roscher, Christiane; Schütz, Martin; Seabloom, Eric William; Standish, Rachel J.; Stevens, Carly J.; Tedder, Michelle J.; Virtanen, Risto; Spohn, Marie (Springer Nature, 2022-09)
      The amount of nitrogen (N) derived from symbiotic N2 fixation by legumes in grasslands might be affected by anthropogenic N and phosphorus (P) inputs, but the underlying mechanisms are not known. Methods We evaluated ...

    • Nutrient enrichment increases invertebrate herbivory and pathogen damage in grasslands 

      Ebeling, Anne; Strauss, Alex T.; Adler, Peter B.; Arnillas, Carlos Alberto; Barrio, Isabel C.; Biederman, Lori A.; Borer, Elizabeth T.; Bugalho, Miguel N.; Caldeira, Maria C.; Cadotte, Marc W.; Peri, Pablo Luis; Blumenthal, Dana M. (British Ecological Society, 2022-02)
      1- Plant damage by invertebrate herbivores and pathogens influences the dynamics of grassland ecosystems, but anthropogenic changes in nitrogen and phosphorus availability can modify these relationships. 2- Using a globally ...
