Isotope geochemistry as a natural tag of fish in Patagonian freshwater environments: the invasive Chinook salmon case
(Elsevier, 2023-05-15)Patagonian aquatic environments have been invaded since the end of the last century by different species of salmonids.Knowing the natal origin and homing/straying rate of the salmonids in colonised environments is essential ... -
Silvopastoral use of Nothofagus antarctica forests in Patagonia: impact on soil microorganisms
(Springer, 2022-09-06)Soil microorganisms contribute to soil carbon storage, soil respiration and nutrient cycling. In south Patagonia, there are scarce studies on carbon (C) and nitrogen (N) in soil microbial biomass (MB). The aim of this work ... -
Climate regionalization of Santa Cruz province, Argentina
(Universidad Nacional Autónoma de México (UNAM), 2023-02-17)La regionalización climática es esencial para la caracterización espacial y temporal de la variabilidad del clima, la producción de pronósticos meteorológicos y el análisis de tendencias a diferentes escalas, así como la ... -
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 ... -
Leaf wettability, anatomy and ultra-structure of Nothofagus antarctica and N. betuloides grown under a CO2 enriched atmosphere
(Elsevier, 2023-01)Increasing CO2 air concentration may affect wettability, anatomy and ultra-structure of leaves of Patagonian forest species, evergreen and deciduous plants potentially responding differently to such CO2 increases. In this ... -
Linking changes in species composition and biomass in a globally distributed grassland experiment
(Wiley, 2022-11-24)Global change drivers, such as anthropogenic nutrient inputs, are increasing globally. Nutrient deposition simultaneously alters plant biodiversity, species composition and ecosystem processes like aboveground biomass ... -
Evaluación de la calidad nutricional en pasturas de gramíneas perennes relacionada con el estado fenológico y el ambiente en el Sur de Santa Cruz
(Universidad Nacional de la Patagonia Austral, 2022-09-30)En la Patagonia Austral la introducción de pasturas destinadas al uso estratégico en las áreas de mayor potencial representa una alternativa de manejo que permitiría aumentar la productividadde los sistemas ganaderos ... -
Composition and Spatial Variation of Germinable Seed Bank in Burned Nothofagus pumilio Forests in Patagonia Argentina
(MDPI, 2022-11-12)The availability of soil-stored seed determines initial plant functional types in post-fire landscapes. We evaluated the post-fire regeneration of Nothofagus pumilio forests, in Patagonia, Argentina, analyzing the soil ... -
Nitrogen but not phosphorus addition affects symbiotic N2 fixation by legumes in natural and semi‑natural grasslands located on four continents
(Springer Nature, 2022-09)The amount of nitrogen (N) derived from symbiotic N2 fixation by legumes in grasslands might be affected by anthropogenic N and phosphorus (P) inputs, but the underlying mechanisms are not known. Methods We evaluated ... -
Relación entre índices de sequía usando datos meteorológicos y satelitales, en la estepa magallánica seca (Patagonia)
(Facultad de Ciencias Económicas, Universidad de Buenos Aires, 2022-04)Los efectos de la sequía impactan en el sector productivo de las distintas regiones, incidiendo en la vegetación, la disponibilidad de agua y las consecuencias que ello ocasiona, por lo que resulta de interés el estudio ... -
Co-limitation toward lower latitudes shapes global forest diversity gradients
(Springer Nature, 2022-08-08)The latitudinal diversity gradient (LDG) is one of the most recognized global patterns of species richness exhibited across a wide range of taxa. Numerous hypotheses have been proposed in the past two centuries to explain ... -
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 forest structure modify understory and livestock occurrence along the natural cycle and different management strategies in Nothofagus antarctica forests
(Springer Nature, 2022-08-17)Sustainable forest management is proposed as a solution for many ecological and socioeconomic trade-offs associated with different forest uses. In Patagonia, silvopastoral systems were proposed to balance provisioning ... -
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 ... -
Flowering and seeding patterns in primary, secondary and silvopastoral managed Nothofagus antarctica forests in South Patagonia
(Taylor & Francis, 2010-06-11)The success ofthe reproductive process in trees depends on abiotic and biotic factors that determine the final outcome of natural regeneration. Silviculture alters biotic and abiotic factors and results in secondary forest ... -
Carbon accumulation along a stand development sequence of Nothofagus antarctica forests across a gradient in site quality in Southern Patagonia
(Elsevier, 2010-06-25)Above- and below-ground C pools were measured in pure even-aged stands of Nothofagus antarctica (Forster f.) Oersted at different ages (5–220 years), crown and site classes in the Patagonian region. Mean tissue C concentration ... -
Putting plant resistance traits on the map: a test of the idea that plants are better defended at lower latitudes
(Wiley, 2011-05-03)It has long been believed that plant species from the tropics have higher levels of traits associated with resistance to herbivores than do species from higher latitudes. A meta-analysis recently showed that the published ... -
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 ... -
Do light and alfalfa responses to cloth and slatted shade represent those measured under an agroforestry system?
(Springer Nature, 2011-02)Shade cloth is commonly used in agroforestry research. It produces a continuous, uniform reduced light environment. Shade cloth and a slatted structure were compared in relation to the inability to represent the light ... -
