    • A fungal endophyte of a palatable grass affects preference of large herbivores 

      Hernández Agramonte, Ignacio M.; Semmartin, María Gisela; Omacini, Marina; Durante, Martin; Gundel, Pedro Emilio; De Battista, Jose Pedro (2018-04)
      Temperate grasses frequently acquire resistance to herbivores through a symbiosis with epichloid fungi that produces alkaloids of variable deterrent effects. However, in those cases without apparent endophyte negative ...

    • Correlations between physical and chemical defences in plants: tradeoffs, syndromes, or just many different ways to skin a herbivorous cat? 

      Moles, Angela; Peco, Begoña; Wallis, Ian R.; Foley, William J.; Poore, Alistair G.B.; Seabloom, Eric William; Vesk, Peter A.; Bisigato, Alejandro Jorge; Cella Pizarro, Lucrecia; Clark, Connie J.; Cohen, Philippe S.; Cornwell, William K.; Edwards, Will; Ejrnæs, Rasmus; Gonzales‐Ojeda, Therany; Graae, Bente J.; Hay, Gregory; Lumbwe, Fainess C.; Magaña‐Rodríguez, Benjamín; Moore, Ben D.; Peri, Pablo Luis; Poulsen, John R.; Stegen, James C.; Veldtman, Ruan; Zeipel, Hugo von; Andrew, Nigel R.; Boulter, Sarah L.; Borer, Elizabeth T.; Cornelissen, Johannes H.C.; Farji Brener, Alejandro Gustavo; DeGabriel, Jane L.; Jurado, Enrique; Kyhn, Line A.; Low, Bill; Mulder, Christa P.H.; Reardon Smith, Kathryn; Rodrıguez Velazquez, Jorge; De Fortier, An; Zheng, Zheng; Blendinger, Pedro Gerardo; Enquist, Brian J.; Facelli, Jose M.; Knight, Tiffany; Majer, Jonathan D.; Martinez Ramos, Miguel; McQuillan, Peter; Hui, Francis K.C. (Wiley, 2013-04)
      Most plant species have a range of traits that deter herbivores. However, understanding of how different defences are related to one another is surprisingly weak. Many authors argue that defence traits trade off against ...

    • Efectos del pastoreo de animales silvestres y domésticos sobre la regeneración de pastizales de la estepa patagónica 

      Pecile, Maria Valeria (Facultad de Agronomía, Universidad de Buenos Aires, 2019)
      El pastoreo representa un factor clave de la estructura y el funcionamiento de las comunidades de pastizal. Los pastizales naturales de zonas áridas y semiáridas son la fuente principal de forraje que sostiene a los ...

    • Effect of population density on diet composition and dietary niche breadth of guanaco (Lama guanicoe, Müller 1776) in northeastern Patagonian steppes 

      Rodriguez, María Victoria; Marino, Andrea Ivana; Borrelli, Laura Beatriz; Bay Gavuzzo, Alhue; Pazos, Gustavo Enrique (Elsevier, 2019-11)
      The optimal foraging theory postulates that as animal population density increases, the progressive decline in preferred forage availability results in changes in diet composition and widening of dietary niche breadth. For ...

    • Herbivores safeguard plant diversity by reducing variability in dominance 

      Mortensen, Brent; Danielson, Brent; Harpole, William Stanley; Alberti, Juan; Arnillas, Carlos Alberto; Biederman, Lori; Borer, Elizabeth T.; Cadotte, Marc William; Dwyer, John Matthew; Hagenah, Nicole; Hautier, Yann; Peri, Pablo Luis; Seabloom, Eric William (2018-01)
      Reductions in community evenness can lead to local extinctions as dominant species exclude subordinate species; however, herbivores can prevent competitive exclusion by consuming otherwise dominant plant species, thus ...

    • Nutrient availability controls the impact of mammalian herbivores on soil carbon and nitrogen pools in grasslands 

      Sitters, Judith; Wubs, E.R. Jasper; Bakker, Elisabeth S.; Crowther, Thomas W.; Adler, Peter B.; Bagchi, Sumanta; Bakker, Jonathan D.; Biederman, Lori; Borer, Elizabeth T.; Cleland, Elsa E.; Eisenhauer, Nico; Firn, Jennifer L.; Gherardi, Laureano A.; Hagenah, Nicole; Hautier, Yann; Hobbie, Sarah E.; Knops, Johannes M.H.; MacDougall, Andrew S.; McCulley, Rebecca L.; Moore, Joslin L.; Mortensen, Brent; Peri, Pablo Luis; Prober, Suzanne M.; Riggs, Charlotte E.; Risch, Anita C.; Schütz, Martin; Seabloom, Eric William; Siebert, Julia; Stevens, Carly J.; Veen, G.F. (Ciska) (Wiley, 2020-02)
      Grasslands are subject to considerable alteration due to human activities globally, including widespread changes in populations and composition of large mammalian herbivores and elevated supply of nutrients. Grassland soils ...

    • Spatial heterogeneity in species composition constrains plant community responses to herbivory and fertilisation 

      Hodapp, Dorothee; Borer, Elizabeth T.; Harpole, William Stanley; Lind, Eric M.; Seabloom, Eric William; Adler, Peter B.; Alberti, Juan; Arnillas, Carlos Alberto; Bakker, Jonathan D.; Biederman, Lori; Cadotte, Marc; Cleland, Elsa E.; Collins, Scott; Fay, Philip A.; Firn, Jennifer L.; Hagenah, Nicole; Hautier, Yann; Iribarne, Oscar; Knops, Johannes M.H.; McCulley, Rebecca L.; MacDougall, Andrew S.; Moore, Joslin L.; Morgan, John W.; Mortensen, Brent; La Pierre, Kimberly J.; Risch, Anita C.; Schütz, Martin; Peri, Pablo Luis; Stevens, Carly J.; Wright, Justin P.; Hillebrand, Helmut (Wiley, 2018-09)
      Environmental change can result in substantial shifts in community composition. The associated immigration and extinction events are likely constrained by the spatial distribution of species. Still, studies on environmental ...
