Climate influence seed production in managed and unmanaged Nothofagus pumilio forests of Southern Patagonia
(SCION, 2024-07-24)Background: Annual seed production is key to understand natural forest dynamics and to apply sustainable forest management. This process is subjected to variations according to annual and seasonal climatic conditions, ... -
Sistemas silvopastoriles en bosques de Nothofagus antárctica: Revisión del conocimiento actual en Patagonia Sur, Argentina.
(INFOR (Chile), 2011-08)Los sistemas silvopastoriles, que combinan en una misma unidad de superficie árboles con pasturas o pastizales bajo pastoreo con ganado, son una alternativa productiva en la región Patagónica, y podrían constituir una ... -
Photosynthetic response to water stress of the main grass species of southern patagonian steppe, Argentina
(Elsevier, 2024-10)Comparative studies of basic physiological performance are needed to give insight of how grass species survive and grow under current and more severe drought predicted in the framework of climate change in arid steppe ... -
Shelterwood cut intensity determines recovery pathways of managed Nothofagus pumilio forests
(SCION, 2024-05-31)Background: Forest harvesting is the main driver of change in forest structure and natural regeneration dynamics during management. Forest recovery after disturbances is important for economic values and ecological processes ... -
Positive feedbacks and alternative stable states in forest leaf types
(Springer Nature, 2024-05-31)The emergence of alternative stable states in forest systems has significant implications for the functioning and structure of the terrestrial biosphere, yet empirical evidence remains scarce. Here, we combine global forest ... -
Different Approaches of Forest Type Classifications for Argentina Based on Functional Forests and Canopy Cover Composition by Tree Species
(MDPI, 2024-04-24)Modern forestry systems rely on typologies of forest types (FTs). In Argentina, several proposals have been developed, but they lack unified criteria. The objective was to compare different approaches, specifically focusing ... -
Vegetation type mapping in Southern Patagonia and its relationship with ecosystem services, soil carbon stock, and biodiversity
(MDPI, 2024-02-29)Vegetation Type (VT) mapping using Optical Earth observation data is essential for the management and conservation of natural resources, as well as for the evaluation of the supply of provisioning ecosystem services (ESs), ... -
In vivo oral toxicity and antioxidant capacity of Nothofagus antarctica (G.Forst.) oerst (ñire) leaves
(Taylor & Francis Group, 2024-01-04)Nothofagus antarctica (NA) is a native tree of Patagonia. Since ancient times, NA leaves were used in infusions for medical and food purposes, but there are no deep insights on its toxicity. The aim of this work was to ... -
Global patterns and environmental drivers of forest functional composition
(Wiley, 2024-02)To determine the relationships between the functional trait composition of forest communities and environmental gradients across scales and biomes and the role of species relative abundances in these relationships. Location: ... -
Quality evaluation of Nothofagus pumilio seeds linked to forest management and climatic events
(Springer Nature, 2024-01-23)Forest ecosystems undergo significant transformations due to harvesting and climate fluctuations, emphasizing the critical role of seeding in natural regeneration and long‑term structural preservation. Climate change further ... -
Anthropogenic Impacts Allowed for the Invasion of Understory Species, Affecting the Sustainability of Management Practices in Southern Patagonia
(MDPI, 2024-01-16)Forest management aims to preserve integrity and ecosystem resilience. Conservation and species invasion patterns must be determined in managed landscapes. The objectives of this study were to identify proxies that allowed ... -
Extreme drought impacts have been underestimated in grasslands and shrublands globally
(National Academy of Sciences (Estados Unidos), 2024-01-08)Climate change is increasing the frequency and severity of short-term (~1 y) drought events—the most common duration of drought—globally. Yet the impact of this intensification of drought on ecosystem functioning remains ... -
Soil organic carbon stocks in native forest of Argentina: a useful surrogate for mitigation and conservation planning under climate variability
(Springer Nature, 2024-01-05)Background The nationally determined contribution (NDC) presented by Argentina within the framework of the Paris Agreement is aligned with the decisions made in the context of the United Nations Framework Convention on ... -
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 ... -
