Pastizales urbanos de la Región Metropolitana de Buenos Aires: Un debate sobre la importancia y desafíos de su conservación
Molina, Cecilia Denisse; Campana, María Sofía; Ciavattini, Mariana Belen; Aradvari Horvat, Sara; Silvoso, María Celeste; Caffaro, María Marta; Jeroham, Mora; Graff, Barbara Pamela (Asociación Argentina de Ecología, 2024-12)La conservación de la vegetación en ambientes urbanos, especialmente de los pastizales, es una problemática poco abordada, pero de gran relevancia ecológica y social. En este artículo proponemos un debate abierto sobre la ... -
Regional and local factors control of beetles’ community composition in arid steppes Patagonia
García, Andrés; Graff, Barbara Pamela; Loydi, Alejandro; Aguiar, Martín (Springer Nature, 2025-10)Understanding how environmental changes impact arthropod communities requires multi-scale studies. Despite their importance, research exploring arthropod diversity across regional gradients while accounting for local ... -
Reserva Municipal de San Vicente (Argentina): caracterización y propuestas de conservación del pastizal
Molina, Cecilia Denisse; Campana, María Sofía; Jeroham, Mora; Graff, Barbara Pamela (Facultad de Agronomía, Universidad de Buenos Aires, 2025-08)Los remanentes de pastizal en áreas protegidas urbanas podrían funcionar como refugios para la biodiversidad frente al crecimiento de la urbanización. A pesar de su potencial valor ecológico, es aún escasa o inexistente ... -
Shrunk coexistence: cattle exclusion and nutrient addition intensify competition between native and exotic grasses with low phenological overlap
Silvoso, María Celeste; Tognetti, Pedro Maximiliano; Armas, Cristina; Casanoves, Fernando; Graff, Barbara Pamela (Wiley, 2025-06)Exotic plants are becoming increasingly common worldwide, often driven by ecological factors such as domestic livestock grazing and soil fertilization. In temperate grasslands, native C4 and exotic C3 grasses are generally ... -
The Bug-Network (BugNet): A Global Experimental Network Testing the Effects of Invertebrate Herbivores and Fungal Pathogens on Plant Communities and Ecosystem Function in Open Ecosystems
Kempel, Anne; Adamidis, George C.; Anadón, José D.; Atkinson, Joe; Auge, Harald; Avtzis, Dimitrios; Bachelot, Benedicte; Bashirzadeh, Maral; Bota, Julien L.; Classen, Aimee; Graff, Barbara Pamela; Oyarzabal, Mariano; Allan, Eric (Wiley, 2025-10)Plants are consumed by a variety of organisms, including herbivores and pathogens, which significantly impact plant biomass, diversity, community composition, and ecosystem functioning. While the impacts of vertebrate ... -
The spatiotemporal stability of plant diversity is disconnected from biomass stability in response to human activities in a South American temperate grassland
Campana, Sofía; Tognetti, Pedro Maximiliano; Alberti, Juan; Graff, Barbara Pamela; Molina, Cecilia D.; Silvoso, María Celeste; Yahdjian, Laura (Elsevier, 2024-12)Human activities alter biomass, nutrient availability, and species dominance in grasslands, impacting their richness, composition, and biomass production. Stability (invariability in time or space) can inform the predictability ...
