Above- and below-ground nutrient tissue concentration and leaf pigment changes in Patagonian woody seedlings grown under light and soil moisture gradients
(Taylor & Francis, 2011-10-28)To understand the ecophysiology of natural regeneration above- and below-ground nutrient tissue concentration and leaf pigment changes in Nothofagus pumilio (lenga) seedlings grown in three light intensities (4%, 26% and ... -
Biomass, carbon and nutrient storage for dominant grasses of cold temperate steppe grasslands in southern Patagonia, Argentina
(Elsevier, 2010-01)We hypothesized that different dominant grasses species display contrasting nutrient accumulation, allocation and conservation strategies. Also, we expect a distinctive pattern of carbon and biomass partitioning according ... -
Changes in nutrient and fibre tissue contents in Nothofagus pumilio trees growing at site quality and crown class gradients
(Elsevier, 2022-02-01)Estimation of biomass and nutrient contents in tree components are essential for evaluating the impact of harvesting on carbon fixation capacity, bio-element recycling, and long-term effect on the balance that influence ... -
Climatic controls of decomposition drive the global biogeography of forest tree symbioses
(Springer Nature, 2019-05-15)The identity of the dominant root-associated microbial symbionts in a forest determines the ability of trees to access limiting nutrients from atmospheric or soil pools1,2, sequester carbon3,4 and withstand the effects of ... -
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 ... -
Effects of Climate and Atmospheric Nitrogen Deposition on Early to Mid-Term Stage Litter Decomposition Across Biomes
(Frontiers Editorial, 2021-07-14)Litter decomposition is a key process for carbon and nutrient cycling in terrestrial ecosystems and is mainly controlled by environmental conditions, substrate quantity and quality as well as microbial community abundance ... -
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 ... -
Foliar N⁄ P ratio and nutrient limitation to vegetation growth on Keerqin sandy grassland of North-east China.
(Wiley, 2011-02-01)To examine whether the critical leaf N ⁄ P ratios (of 14, 16) are valid to test nutrient limitation in the context of semi-arid sandy grasslands, an experiment was conducted on a Keerqin sandy grassland in North-east China ... -
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 ... -
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 ... -
Litter decomposition and nutrients dynamics in Nothofagus antarctica forests under silvopastoral use in Southern Patagonia.
(Springer, 2012-01-24)The role of environmental variables on litter decomposition and its nutrient release in Nothofagus antarctica forest in Patagonia is poorly understood. Moreover, in these forests under silvopastoral use there are few ... -
Litterfall and nutrients return in Nothofagus antarctica forests growing in a site quality gradient with different management uses in Southern Patagonia
(2015-01)We evaluated the annual litterfall and nutrients return in primary forests of Nothofagus antarctica growing at three different site classes (SC) (III, IV and V) and compared two of these forests with adjacent stands under ... -
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 ... -
Microorganismos del suelo en bosques de ñire en Patagonia Sur: resultados preliminares.
(Instituto Forestal (INFOR), 2017-08)Nothofagus antarctica (ñire) es una especie nativa del bosque andino-patagónico que se extiende desde los 36º 30’ hasta los 56º 00’ LS. Es la segunda especie en importancia de la provincia de Santa Cruz, Argentina. En estos ... -
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 ... -
Opposing community assembly patterns for dominant and non-dominant plant species in herbaceous ecosystems globally
(Wiley Ecology and evolution, 2021-11-22)Biotic and abiotic factors interact with dominant plants—the locally most frequent or with the largest coverage—and nondominant plants differently, partially because dominant plants modify the environment where nondominant ... -
Plasticidad ecofisiológica de plántulas de Nothofagus pumilio frente a combinaciones de niveles de luz y humedad en el suelo
(Asociación Argentina de Ecología, 2011)Las propuestas silvícolas para el manejo de los bosques de Nothofagus pumilio se basan sobre la apertura del canopeo para estimular el crecimiento de la regeneración natural; de esta manera se incrementa la disponibilidad ... -
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 ... -
Sheep faeces decomposition and nutrient release across an environmental gradient in Southern Patagonia
(2017-04)In Southern Patagonia, most of the land ranging from the mountains to the sea in contrasting environmental conditions is devoted to extensive sheep farming. Existing estimations indicate that in ecosystems under livestock ... -
