Soil salinization in Patagonian meadows with different grassland condition
(2018-08)Patagonian meadows (locally named “mallines”) are wetlands that develop in the lower parts of the landscape, were runoff water accumulates, and organic and humid soils appear, contrasting with the surrounding steppe. An ... -
Soil variability and crop yield gaps in two village landscapes of Burkina Faso
(Springer, 2016-07)Low crop yields in the savannah zones of West Africa are commonly attributed to rainfall deficits and poor soil fertility. In this study, an assessment was made on how the position of fields belonging to different farm ... -

(EEA Bariloche, INTA, 2021-08)La Meseta de Somuncura es un Área Natural Protegida. Las condiciones ambientales favorecen la diversificación de especies vegetales e incluso posee especies endémicas. En particular, los coirones son especies de esta región ... -
Sondeo estratificado de demandas y su validación consultiva
(Ediciones INTA, 2013)El Sondeo Estratificado de Demandas (SED) permite rescatar, a través de entrevistas semi-estructuradas y observación situacional, las demandas explícitas de los productores y hacer inferencias sobre demandas implícitas, ... -
Sorption characteristics of rosehip, apple and tomato pulp formulations as determined by gravimetric and hygrometric methods
(Elsevier, 2013-06)The sorption characteristics of three formulations based on rosehip, apple and tomato pulp, added with saccharides, and aimed at preparing fruit leathers, were studied. Desorption isotherms were determined at 20 and 40 °C, ... -
Spatial density‐dependent parasitism and specificity in the robber fly Mallophora ruficauda (Diptera: Asilidae)
(Wiley, 2010-02)The density‐dependence in parasitism by the robber fly Mallophora ruficauda (Diptera: Asilidae) on scarab beetle larvae (Coleoptera: Scarabaeidae) populations was studied in the present research. Mallophora ruficauda is a ... -
Spatial distribution of volcanic ash deposits of 2011 Puyehue-Cordón Caulle eruption in Patagonia as measured by a perturbation in NDVI temporal dynamics
(2018-03)Volcanic ash fallout is a recurrent environmental disturbance in forests, arid and semi-arid rangelands of Patagonia, South America. The ash deposits over large areas are responsible for several impacts on ecological ... -
Spatial dynamics of a Sirex noctilio woodwasp population within a pine plantation in Patagonia, Argentina
(Wiley, 2007-12)The woodwasp Sirex noctilio F. (Hymenoptera: Siricidae) is probably the most important pest of pine tree plantations of the southern hemisphere. We studied the spatial arrangement of an endemic population of the woodwasp ... -
Spatial pattern of attacks of the invasive woodwasp Sirex noctilio, at landscape and Stand Scale
(2015-05-18)Invasive insect pests are responsible for important damage to native and plantation forests, when population outbreaks occur. Understanding the spatial pattern of attacks by forest pest populations is essential to improve ... -
Spatiotemporal outbreak dynamics of bark and wood-boring insects
(Elsevier, 2023-02)Bark and wood-boring insects (BWI) can cause important disturbances in forest ecosystems, and their impact depends on their spatiotemporal dynamics. Populations are usually at stable, low densities but can be disrupted by ... -
