Co-limitation toward lower latitudes shapes global forest diversity gradients
(Springer Nature, 2022-08-08)The latitudinal diversity gradient (LDG) is one of the most recognized global patterns of species richness exhibited across a wide range of taxa. Numerous hypotheses have been proposed in the past two centuries to explain ... -
Compositional shifts of alpine plant communities across the high Andes.
(Wiley, 2023-09)Aim: Climate change is transforming mountain summit plant communities worldwide, but we know little about such changes in the High Andes. Understanding large-scale patterns of vegetation changes across the Andes, and the ... -
Diversity patterns in the steppe of Argentinean Southern Patagonia: Environmental drivers and impact of grazing
(NOVA Science Publishers, 2013)The steppe ecosystem, mainly characterised by the presence of tussock, short grasses and shrubs, covers 85% of the total area in Santa Cruz Province and 25% in Tierra del Fuego Island. Most of the land in the Patagonian ... -
Efecto de las características forestales y del ambiente sobre el sotobosque de bosques de Nothofagus antarctica en Tierra del Fuego
(Red Argentina de Ciencia y Tecnología Forestal, 2023-03-27)La vegetación del sotobosque es parte integral de los bosques, cumpliendo un rol fundamental para el reciclado de nutrientes y energía, el soporte de la biodiversidad y sus interacciones, y la estabilidad/resiliencia del ... -
Environmental heterogeneity modulates the effect of plant diversity on the spatial variability of grassland biomass
(Springer Nature, 2023-03-31)Plant productivity varies due to environmental heterogeneity, and theory suggests that plant diversity can reduce this variation. While there is strong evidence of diversity effects on temporal variability of productivity, ... -
Evenness mediates the global relationship between forest productivity and richness
(British Ecological Society, 2023-06-07)1. Biodiversity is an important component of natural ecosystems, with higher species richness often correlating with an increase in ecosystem productivity. Yet, this relationship varies substantially across environments, ... -
General destabilizing effects of eutrophication on grassland productivity at multiple spatial scales
(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, ... -
Herbivory and nutrients shape grassland soil seed banks
(Springer Nature, 2023-07-04)Anthropogenic nutrient enrichment and shifts in herbivory can lead to dramatic changes in the composition and diversity of aboveground plant communities. In turn, this can alter seed banks in the soil, which are cryptic ... -
Linking changes in species composition and biomass in a globally distributed grassland experiment
(Wiley, 2022-11-24)Global change drivers, such as anthropogenic nutrient inputs, are increasing globally. Nutrient deposition simultaneously alters plant biodiversity, species composition and ecosystem processes like aboveground biomass ... -
Monitoreo de indicadores de degradación en mallines bajo pastoreo ovino en el Sur de Santa Cruz
(EEA Santa Cruz, INTA, 2014-04)Los principales disturbios que afectan los mallines en Patagonia están vinculados con alteraciones en su dinámica hídrica y el pastoreo intensivo y continuo durante períodos prolongados (Raffaele, 1999). Estos disturbios ...
