Mineral fertilization impacts microbial activity and endophytic fungi but not microbial biomass in semiarid grasslands
(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 ... -
Value of Biodiversity on Patagonian Rangeland: Estimation via a Hedonic Price Index
(Elsevier, 2024-01)Plant diversity has long been linked to an increase in ecosystem productivity and function, but concrete examples in which ecosystem services are linked to diversity at the scale at which management decisions are taken are ... -
Producción de lechuga (Lactuca sativa) en hidroponía en sistema Indoor con luces artificiales = Lettuce (Lactuca sativa) production in hydroponics indoor system with artificial lights
(Universidad Nacional de la Patagonia Austral, 2023-12-21)En la localidad de Río Gallegos, el fotoperiodo disminuye en época invernal y lo torna limitante para la producción de hortícolas. Motivo por el cual, para obtener cultivos todo el año en esta zona, es necesario realizar ... -
Nuevo registro del gato del pajonal grupo Leopardus colocola para el Chaco Seco de Argentina
(Sociedad Argentina para el Estudio de los Mamíferos (SAREM), 2023-08-04)La distribución real del grupo Leopardus colocola en el Chaco argentino es poco conocida. Este registro surgió como parte de un monitoreo con trampas cámara de mamíferos nativos en el Chaco Seco Argentino en áreas con ... -
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 ... -
Potential biodiversity map of bird species (Passeriformes): Analyses of ecological niche, environmental characterization and identification of priority conservation areas in southern Patagonia
(Elsevier, 2023-06)Different methodologies try to identify priority conservation areas (PCA) to improve habitat conservation and decrease human pressures over bird species at coarse-scale. Map of potential biodiversity (PB) can identify PCA ... -
Integrated global assessment of the natural forest carbon potential
(Springer Nature, 2023-12-07)Forests are a substantial terrestrial carbon sink, but anthropogenic changes in land use and climate have considerably reduced the scale of this system1. Remote-sensing estimates to quantify carbon losses from global ... -
The global biogeography of tree leaf form and habit
(Springer Nature, 2023-11)Understanding what controls global leaf type variation in trees is crucial for comprehending their role in terrestrial ecosystems, including carbon, water and nutrient dynamics. Yet our understanding of the factors influencing ... -
Nothing lasts forever: Dominant species decline under rapid environmental change in global grasslands
(British Ecological Society, 2023-11)1. Dominance often indicates one or a few species being best suited for resource capture and retention in a given environment. Press perturbations that change availability of limiting resources can restructure competitive ... -
The positive effect of plant diversity on soil carbon depends on climate
(Springer Nature, 2023-10-19)Little is currently known about how climate modulates the relationship between plant diversity and soil organic carbon and the mechanisms involved. Yet, this knowledge is of crucial importance in times of climate change ... -
Native diversity buffers against severity of non-native tree invasions
(Springer Nature, 2023-09)Determining the drivers of non-native plant invasions is critical for managing native ecosystems and limiting the spread of invasive species1,2. Tree invasions in particular have been relatively overlooked, even though ... -
Forest carbon management strategies influence storage compartmentalization in Nothofagus antarctica forest landscapes
(Canadian Science Publishing, 2023-10)Silvopastoral systems are one of the strategies proposed to manage natural forests in southern Patagonia for livestock and timber purposes. In the context of climate change, it is necessary to design new management proposals ... -
Restauración por recolonización de especies nativas en pasturas sembradas en ambientes semiáridos en Patagonia
(Facultad de Agronomía, Universidad Nacional de La Pampa, 2023-06-05)En Patagonia austral el sobrepastoreo provoca cambios irreversibles en los pastizales. La sucesión secundaria en pasturas comerciales podría promover parcialmente la recuperación de especies nativas. Se estudiaron lotes ... -
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 ... -
Microclimatic conditions restrict the radial growth of Nothofagus antarctica regeneration based on the type of forest environment in Tierra del Fuego
(MDPI, 2023-05-27)Regeneration is crucial for forest continuity in natural and managed stands. Analyzing intra-annual dynamics can improve the understanding between growth and climate, identifying regeneration survival thresholds. The ... -
Climate change-related growth improvements in a wide niche-breadth tree species across contrasting environments
(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 ... -
