Are the rhizosphere fungal communities of Nothofagus alpina established in two different environments influenced by plant genetic diversity?
(Elsevier, 2020-10)Fungi are one of the most important soil microorganisms due to their abundance and the importance of the ecosystem processes they carry out, like decomposition, nutrient cycling, and the establishment of biological ... -
Are winter rangelands enough to satisfy the nutritional requirements of late‑gestation transhumant goats in Patagonia?
(Springer, 2022-08-03)Transhumant herds graze across two different rangeland types according to the season. Winter rangelands differ from summer rangelands in the amount and quality of available fodder, with the former being the less productive. ... -
Arid and semiarid rangeland responses to non-stationary temporal dynamics of environmental drivers
(Elsevier, 2022-08)Temporal ecology is a growing research field aimed at understanding how temporal dynamics structure ecological systems in a changing environment. Ecosystems are exposed to accelerating environmental changes —mainly driven ... -
Ash resuspension related to the 2011–2012 Cordón Caulle eruption, Chile, in a rural community of Patagonia, Argentina
(2018)The 2011–2012 Cordón Caulle eruption emitted about 1 km3 of rhyodacitic tephra. Dominant westerly winds in the region caused most of the primary tephra to deposit in neighboring Argentina. In addition to the impact of ... -
Ashes in the air : the effects of volcanic ash emissions on plant-pollinator relationship and possible consequences for apiculture
(2013-05)El rendimiento de forrajeo de los polinizadores podría ser alterado por las flores de cenizas volcánicas contaminados, polen y néctar. Se utilizó la abeja melífera (Apis mellifera) como organismo modelo para comprender los ... -
Aspectos teóricos en el diseño de pruebas de progenie
(Ediciones INTA, 2018-11)El concepto de prueba de progenie ha sido aplicado por criadores de ganado doméstico a lo largo de la historia. Hace más de dos mil años el erudito romano Marco Terencio Varrón escribió en su libro De re Rustica Pecuaria: ... -
Assessing farmer perceptions on livestock intensification and associated trade-offs using fuzzy cognitive maps; a study in mixed farming systems in the mid-hills of Nepal
(Wiley, 2023-02)Intensified livestock production is considered as a promising pathway for smallholder farmers. Nevertheless, this pathway may entail prohibitive investment requirements of labour, capital or trade-offs at farm level that ... -
Assessing resilience and adaptability in agroecological transitions
(Elsevier, 2020-09)Guidelines are needed to support research and action on sustainable transitions towards more resilient and adaptable agroecosystems. Here I present an operationable and simple framework with theoretical underpinning to ... -
Assessing soil microbial biodiversity as affected by grazing and woody vegetation cover in a temperate savannah
(Wiley, 2021-04-07)Although it is well established that land use and management affects soil microbial biodiversity, with consequences for soil-mediated ecosystem services, knowledge on human-induced variability in soil bacterial and fungal ... -
Assessing the magnitude of impact of volcanic ash deposits on Merino wool production and fibre traits in the context of a drought in North-west Patagonia, Argentina
(CSIRO Publishing, 2014-02)Environmental variability is a key feature of arid and semiarid rangelands worldwide. Drought is one of the main sources of variation in most extensive livestock production systems in arid environments, with biophysical ... -
Assessing Tn5 and sleeping beauty for transpositional transgenesis by cytoplasmic injection into bovine and ovine zygotes
(2017-03-16)Transgenic domestic animals represent an alternative to bioreactors for large-scale production of biopharmaceuticals and could also provide more accurate biomedical models than rodents. However, their generation remains ... -
Assessment of resistance to xylem cavitation in cordilleran cypress using near-infrared spectroscopy
(Elsevier, 2020-04)Characterizing drought resistance of forest trees is an important aim in the worldwide context of increasing forest decline and dieback. Furthermore, wood demand is increasing all around the world, urging the need for the ... -
Autorraleo: alternativa para determinar la pendiente de la relación lineal tamaño-densidad, mediante su impacto en la estimación del volumen del rodal = Self-thinning: alternative to determine the slope of the relationship size-density, by means of its impact on the estimation of stand volume
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2019)Los índices de densidad de rodal son utilizados para diseñar tablas de producción, diagramas de manejo de la densidad, simuladores de crecimiento y establecer regímenes de raleo, siendo el más difundido el índice de rodal ... -
Avispas exóticas en la Patagonia: la importancia de la ecología de invasiones en el manejo de plagas
