Anchored in 'average thinking' in studies of arid rangeland dynamics - The need for a step forward from traditional measures of variability
(2015-02)There is a wide consensus that arid and semi-arid environments are highly variable in space and time. The most frequent approaches to describe and analyze arid and semi-arid rangelands are based on the usage of averages ... -

(Sociedad de Medicina Veterinaria, 2004)Se realizó una recopilación y análisis de la información técnica disponible sobre Brucelosis Bovina de la Patagonia Argentina. Se confirma la presencia de la enfermedad en dicha región desde la década del 50 y su actual ... -
Antioxidant capacity of frozen Pleurotus ostreatus during convective drying
(Universidad de Puebla, México, 2016-01)The influence of drying conditions on antiradical power, total phenols, flavonoids, and surface color in frozen basidiocarps of Pleurotus ostreatus was studied. Drying was carried out in an experimental rig, air velocity ... -
Apports des typologies d'exploitations aux démarches de conception en agriculture de conservation : une étude de cas dans le nord du Vietnam = Exploiting farm typologies for designing conservation agriculture systems: a case study in northern Vietnam
(2015-03)Dans deux districts montagneux du nord du Vietnam, l’agriculture de conservation (AC) est envisage´e pour re´duire l’impact environnemental de la culture de maı¨s sur pente. Dans ce contexte, notre e´tude vise l’e´laboration ... -
Archetypal temporal dynamics of arid and semi-arid rangelands
(Elsevier, 2021-03)The way in which temporal dynamics structure ecological systems under the influence of a changing environment has long interested ecologists. Tackling the hierarchical structure of complex temporal patterns is a necessary ... -
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 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 ... -
