Marco conceptual y propuesta metodológica para el desarrollo de observatorios de sustentabilidad rural
(EEA Bariloche, 2015)La preocupación del INTA por los procesos de desarrollo territorial sustentable, las demandas recogidas en diversos territorios, y la complejidad implícita en la sustentabilidad, ha llevado a trabajar en el desarrollo de ... -
What can possibly go wrong? The risks of introducing soil microorganisms from Antarctica into South America = ¿Qué puede salir mal? : Los riesgos de introducir microorganismos del suelo de la Antártida en América del Sur
(2015)Endophytic fungi form mutualistic associations with plant roots which can increase plant survival and resistance to stress. Recently, it has been proposed that endophytic fungi from Antarctica should be used to facilitate ... -
Weak trophic links between a crab-spider and the effective pollinators of a rewardless orchid
(2015-01)Sit and wait predators hunting on flowers are considered to be exploiters of plant–pollinator mutualisms. Several studies have shown that plant–pollinator interactions can be highly susceptible to the impact of a third ... -
Behavioural response of the woodwasp Sirex noctilio to volatile emissions of its fungal symbiont
(2015-01)The wood-boring wasp, Sirex noctilio, is a global invasive pest that infects and kills pine trees by inoculating spores of a symbiotic fungus (Amylostereum areolatum) at oviposition. Wasp larvae depend on fungal growth to ... -
Dendrogeomorphic reconstruction of flash floods in the Patagonian Andes
(Elsevier, 2015-01-01)Flash floods represent a significant natural hazard in small mountainous catchments of the Patagonian Andes and have repeatedly caused loss to life and infrastructure. At the same time, however, documentary records of past ... -
Point of no return? Rehabilitating desgraded soils for increased crop productivity on samllholder farmas in eastern Zimbabwe
(2015-02)Soil degradation is a major threat to Southern Africa's agricultural production. Crops show generally weak responses to mineral fertilizers on degraded soils. A three-year study was conducted between 2009 and 2012 on ... -
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 ... -
Classical biological control of an invasive forest pest : a world perspective of the management of Sirex noctilio using the parasitoid Ibalia leucospoides (Hymenoptera: Ibaliidae)
(2015-02)Classical biological control is a key method for managing populations of pests in long-lived crops such as plantation forestry. The execution of biological control programmes in general, as the evaluation of potential ... -
Relevamiento sanitario en bovinos de una comunidad indígena de la provincia del Neuquén, Argentina = Health survey in cattle from an indigenous community from Neuquén province, Argentina
(2015-02)Debido al escaso conocimiento que se posee sobre el estado sanitario del ganado perteneciente a comunidades indígenas de la Patagonia, se realizó un estudio que involucró a 47 crianceros de la Comunidad Millaín Currical, ... -
Tradeoffs around crop residue biomass in smallholder crop-livestock systems - Whatïs next?
(2015-03)Much has been written on the tradeoffs that smallholder farmers face when having to allocate their biomass resources among competing objectives such as feed, fuel, mulch, compost or the market. This paper summarises yet a ... -
Biomass use trade-off in cereal cropping systems in the developing world : overview
(2015-03)Agricultural systems variously produce food, feed, fiber, fuel, and environmental goods. The relative emphasis varies over space and time – associated inter alia to inter-related developments in demand, technology and ... -
From farm scale to village scale trade-offs : cereal crop residues use in an agro-pastoral system of the Sudanian zone of Burkina Faso
(2015-03)Traditionally, cereal crop harvest residues are communally grazed by the ruminant herds of villagers and transhumant pastoralists in the agro-pastoral systems which predominate in the savannah zone of West Africa. We ... -
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 ... -
Estimating soil organic carbon through loss on ignition: effects of ignition conditions and structural water loss
(John Wiley & Sons Ltd, 2015-03)Loss on ignition (LOI) is one of the most widely used methods for measuring organic matter content in soils but does not have a universal standard protocol. A large number of factors may influence its accuracy, such as ... -
Rehydration of Rosa rubiginosa Fruits Dried with Hot Air
(Taylor & Francis, 2015-03)The effect of perforation, drying temperature, and rehydration temperature on the rehydration kinetics of Rosa rubiginosa fruits was investigated. Before drying, half of the fruit sample was perforated three times at ... -
Preferencias de hospedador y hábitat de insectos fitófagos asociados a Nothofagus spp.
(Centro Regional Universitario Bariloche, Universidad Nacional del Comahue, 2015-03)El bosque nativo Andino- Patagónico se caracteriza por la presencia de diversas especies de Nothofagus (Fagales: Nothofagaceae). Estas especies leñosas no sólo representan una pieza del patrimonio natural, sino que además ... -
No evidence of enemy release in pathogen and microbial communities of comnon wasps [Vespula vulgaris] in their native and introduced range
(2015-03-23)When invasive species move to new environments they typically experience population bottlenecks that limit the probability that pathogens and parasites are also moved. The invasive species may thus be released from biotic ... -
Halfway encounters: Meeting points of colonization routes among the southern beeches Nothofagus pumilio and N. antarctica
(2015-04)The Patagonian region is characterized by a complex biogeographic history, with evidence of deep phylogeographic breaks shared among species. Of particular interest to conservation is the nature of colonization and settlement ... -
