Agroforestry landscapes and global change: landscape ecology tools for management and conservation
(Springer, 2012-07)Forest ecosystems are impacted by multiple uses under the influence of global drivers, and where landscape ecology tools may substantially facilitate the management and conservation of the agroforestry ecosystems. The use ... -
Biodiversity and ecological long-term plots in Southern Patagonia to support sustainable land management: The case of PEBANPA network
(2016-12)Historically, interactions and trends between biodiversity, ecosystem function (EF) and land use practices in southern Patagonia (Argentina) have been largely undocumented and poorly understood. Since 2002, 1214 permanent ... -
Biodiversity potential of Nothofagus forests in Tierra del Fuego (Argentina): tool proposal for regional conservation planning
(2016-09)It is difficult to map and quantify biodiversity at landscape level in areas with low data availability, despite demand from decision-makers. We propose a methodology to determine potential biodiversity pattern using habitat ... -
Carbon pool dynamics after variable retention harvesting in Nothofagus pumilio forests of Tierra del Fuego
(Springer Nature, 2023-01-23)Background It is necessary to determine the implications for managing forest stands using variable retention harvesting for maintaining carbon and for calculating the effects of different harvesting practices on above‑ and ... -
Cartografía de un nuevo Modelo de Estados y Transiciones de la Estepa Magallánica Seca en la Patagonia argentina
(Asociación Argentina de Ecología, 2021-08)Analizamos 103 censos de vegetación de la Estepa Magallánica Seca, un área de 12000 km2 de estepas graminosas semiáridas en el SE de la Patagonia. Los objetivos del presente trabajo fueron ampliar el relevamiento de ... -
Change in functional trait diversity mediates the effects of nutrient addition on grassland stability
(British Ecological Society, 2024-09-02)1. Nutrient enrichment impacts grassland plant diversity such as species richness, functional trait composition and diversity, but whether and how these changes affect ecosystem stability in the face of increasing climate ... -
Changes derived by the silvopastoral management in Nothofagus antarctica forests of Tierra del Fuego compared to other productive environments
(Springer Nature, 2024-07-05)Silvopastoral systems (SPS) are suggested to promote a balance between productive alternatives and ecological values. The aim of this study was to determine the changes generated by SPS (thinning + livestock) in Nothofagus ... -
Conceptual framework to define management strategies for silvopastoral systems in native forests
(Asociación Argentina de Ecología., 2022-08-25)Most of the native forests in Argentina are used for livestock production with little sustainable silvopastoral management. Our objective here is to discuss different management strategies where natural and human capital ... -
Conservation value and ecosystem service provision of Nothofagus antarctica forests based on phenocluster categories
(Springer Nature, 2025-01-20)Traditional approaches of forest classifications were based on tree species composition, but recently combine phenology and climate to characterise functional (cyclic and seasonal greenness) rather than structural or ... -
Current trends in silvopastoral systems
(Springer Nature, 2024-10-26)In Latin America, SPS are practiced in various ecosystems in humid and dry broadleaved forests, temperate forests, tropical and subtropical coniferous forests, and savannas. These ecosystems range from sea level up to> ... -
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 ... -
Diversidad de plantas vasculares en bosques continuos y relictuales de Nothofagus antárctica (Nothofagaceae) en Patagonia austral
(Universidad de Magallanes, Chile, 2019)La historia de los bosques de Nothofagus antarctica (ñire, ñirre) está asociada a profundos disturbios geológicos y climáticos. A éstos se le suman los disturbios más recientes, que junto a los usos culturales de la tierra ... -
Dominant native and non‐native graminoids differ in key leaf traits irrespective of nutrient availability
(Wiley, 2020-03-12)Nutrient enrichment is associated with plant invasions and biodiversity loss. Functional trait advantages may predict the ascendancy of invasive plants following nutrient enrichment but this is rarely tested. Here, we ... -
Experimental Exclusion of Guanaco Grazing Increases Cover, Diversity, Land Function and Plant Recruitment in Patagonia
(Tech Science Press, 2024-07-30)Semiarid Patagonia represents 25% of the rangeland area in Argentina, and sheep overgrazing has degraded about a third of it in the past. In this century, depleted domestic stocks have mostly stabilized, but Guanaco ... -
Herbivores safeguard plant diversity by reducing variability in dominance
(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 ... -
Holistic versus continuous grazing in Patagonia: A station-scale case study of plant and animal production
(Elsevier, 2021-01)We compared animal and vegetation responses of a 13 600-ha area under holistic grazing management (HGM) with a similar area under continuous grazing (CGM) in a Patagonian station. Limitations were a dry 2012 −2016 experimental ... -
Human appropriation of net primary production related to livestock provisioning ecosystem services in Southern Patagonia
(MDPI, 2022-06-22)Human appropriation of net primary productivity (HANPP) integrates ecological and socioeconomic perspectives on land use by quantifying the amount of net primary production (NPP) appropriated by society through biomass ... -
Improving the knowledge of plant potential biodiversity-ecosystem services links using maps at the regional level in Southern Patagonia.
(Springer, 2021-07-22)Background: Biodiversity supports multiple ecosystem services, whereas species loss endangers the provision of many services and affects ecosystem resilience and resistance capacity. The increase of remote sensing techniques ... -
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 ... -
Interactive and unimodal relationships between plant biomass, abiotic factors, and plant diversity in global grasslands.
(Springer Nature, 2025-01-21)Grasslands cover approximately a third of the Earth’s land surface and account for about a third of terrestrial carbon storage. Yet, we lack strong predictive models of grassland plant biomass, the primary source of carbon ...
