Are Patagonia grasslands being overgrazed? A response to Marino et al. (2020)
(Wiley, 2020-09)Based upon primary productivity estimates, Oliva et al. (2019) concluded that, at the end of last century and after long periods of overgrazing, Patagonia's domestic stocks adjusted to regional‐scale herbivore carrying ... -
The MARAS dataset, vegetation and soil characteristics of dryland rangelands across Patagonia
(2020)We present the MARAS (Environmental Monitoring of Arid and Semiarid Regions) dataset, which stores vegetation and soil data of 426 rangeland monitoring plots installed throughout Patagonia, a 624.500 km2 area of southern ... -
Conservation values of understory vascular plants in even- and uneven-aged Nothofagus antarctica forests
(Springer, 2020-09)Usually, stands with aging trees are considered forests with higher conservation values, regardless their structural diversity and other functional attributes. Natural stands present a wide range of age structures, from ... -
Soil microbial communities respond to an environmental gradient of grazing intensity in south Patagonia Argentina
(Elsevier, 2020)Soil microorganisms communities regulate key functions in terrestrial ecosystems and contributes to the formation of stable organic matter and hence climate change mitigation. The structure, diversity and activity of soil ... -
Allometric relations for biomass partitioning of Nothofagus antarctica trees of different crown classes over a site quality gradient
(Elsevier, 2010-03)Data on tree biomass are essential for understanding the forest carbon cycle and plant adaptations to the environment. We determined biomass accumulation and allometric relationships in the partitioning of biomass between ... -
Ojos que no ven… ¿Qué podemos hacer para incluir más a la fracción subterránea en estudios de vegetación?
(Asociación Argentina de Ecología, 2020-06)Conocer la estructura y el funcionamiento de la fracción subterránea de la vegetación es fundamental para comprender numerosos procesos que ocurren en distintos niveles de organización. Sin embargo, dicha fracción fue menos ... -
Desarrollo de la regeneración a lo largo del ciclo del manejo forestal de un bosque de Nothofagus pumilio: 2. Incidencia del ramoneo de Lama guanicoe
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 1999)Los Nothofagus presentan inconvenientes para regenerarse cuando son sometidos a disturbios sistemáticos y permanentes, como lo es el sobrepastoreo. Los bosques de Tierra del Fuego, libres de ganado vacuno, son afectados ... -
Desarrollo de la regeneración a lo largo del ciclo del manejo forestal de un bosque de Nothofagus pumilio: 1. Incidencia de la cobertura y el aprovechamiento o cosecha
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 1999)La Lenga es la especie forestal de mayor impacto económico en la Patagonia. Dentro del bosque es posible encontrar una población importante de renovales, cuya supervivencia depende de la cantidad de luz que el dosel arbóreo ... -
Turno de corta y posibilidad de los bosques de lenga (Nothofagus pumilio) en Tierra del Fuego (Argentina) = Rotation length and sustainable use of lenga (Nothofagus pumilio) forests in Tierra del Fuego (Argentina)
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2004)La ordenación forestal regional es una herramienta indispensable para desarrollar políticas forestales que protejan los bosques naturales, en el marco del manejo sustentable y del uso múltiple. Para ello se debe contar con ... -
Microbial processing of plant remains is co‐limited by multiple nutrients in global grasslands
(Wiley, 2020-06)Microbial processing of aggregate‐unprotected organic matter inputs is key for soil fertility, long‐term ecosystem carbon and nutrient sequestration and sustainable agriculture. We investigated the effects of adding multiple ... -
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 ... -
Nutrient availability controls the impact of mammalian herbivores on soil carbon and nitrogen pools in grasslands
(Wiley, 2020-02)Grasslands are subject to considerable alteration due to human activities globally, including widespread changes in populations and composition of large mammalian herbivores and elevated supply of nutrients. Grassland soils ... -
Hepatitis parasitaria por Lamanema chavezi en guanacos (Lama guanicoe) faenados en la Provincia de Santa Cruz, Argentina
(Sociedad de Medicina Veterinaria, 2020-01)Durante la zafra 2017-18 en un frigorífico de la localidad de Río Gallegos, Argentina, se detectaron lesiones en hígados de guanacos (Lama guanicoe) a la faena. Con el fin de caracterizar y determinar la causa de las ... -
Essential Nutrient and Trace Element Foliar Resorption of Two Co-Existing Nothofagus Species Grown Under Different Environmental Conditions in Southern Patagonia
(Frontiers Media, 2019-11)Nutrient resorption is crucial for mineral element conservation and efficiency of forest species, but knowledge on its significance and the mechanisms involved is still limited for most species and habitats. Focusing on ... -
Institutional challenges in putting ecosystem service knowledge in practice
(Elsevier, 2018-02)The promise that ecosystem service assessments will contribute to better decision-making is not yet proven. We analyse how knowledge on ecosystem services is actually used to inform land and water management in 22 case ... -
Isotopic evidence for oligotrophication of terrestrial ecosystems
(Springer Nature, 2018)Human societies depend on an Earth system that operates within a constrained range of nutrient availability, yet the recent trajectory of terrestrial nitrogen (N) availability is uncertain. Examining patterns of foliar N ... -
Spatial heterogeneity in species composition constrains plant community responses to herbivory and fertilisation
(Wiley, 2018-09)Environmental change can result in substantial shifts in community composition. The associated immigration and extinction events are likely constrained by the spatial distribution of species. Still, studies on environmental ... -
Leaf nutrients, not specific leaf area, are consistent indicators of elevated nutrient inputs
(Nature Research, 2019)Leaf traits are frequently measured in ecology to provide a ‘common currency’ for predicting how anthropogenic pressures impact ecosystem function. Here, we test whether leaf traits consistently respond to experimental ... -
Sensitivity of global soil carbon stocks to combined nutrient enrichment
(Wiley, 2019-06)Soil stores approximately twice as much carbon as the atmosphere and fluctuations in the size of the soil carbon pool directly influence climate conditions. We used the Nutrient Network global change experiment to examine ... -
Raspberries and gooseberries in south Patagonia: Production, fruit quality, morphology and phenology in two environmental conditions
(Elsevier, 2019)Fine fruits as raspberry and gooseberries represent the second production with the largest area cultivated in Santa Cruz province (Argentina), and this activity is usually carried out by family farmers in outdoor conditions. ...
