Water status of plants under strips management in shrub-grass steppe of Southern Patagonia
(IRC, 2011-04-02)In the province of Santa Cruz Junellia tridens shrublands cover 2,8 million ha. These cummunities grow on site with coarser textured soil are dominated by 60-70 cm tall shrubs. Water is the most important factor regulating ... -
Water table contribution to alfalfa water use in different environments of the Argentine Pampas
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2002)In the Argentine Pampas, although the water table is considered an important source of water supply for the alfalfa crop, it has not been previously quantified.The goal of this study was to estimate ... -
Water table depth affects persistence and productivity of alfalfa in Central Argentina
(Elsevier, 2019-04)Alfalfa (Medicago sativa L.) is one of the most sown perennial legumes in the world. Water table depth can be both an opportunity and a threat for this crop. In this study we analyzed 20 years of field experimental data ... -
Water temperature and microenvironmental factors predict the presence and detection of the snail host of Fasciola hepatica in Andean Patagonia
(Elsevier, 2024-07)The transmission of Fasciola hepatica occurs only where there are -or recently were- aquatic or amphibious snails of the Lymnaeidae family, the intermediate host of this parasite. Direct detection of these snails is ... -
Water use of wheat, corn and sunflower in the semiarid pampas = Uso del agua por trigo, maíz y girasol en la región semiárida pampeana
(Asociación Argentina de la Ciencia del Suelo, 2017)Crop water use in semiarid environments allows designing management strategies to improve water use efficiency. Our objective was to estimate wheat (Triticum aestivum L.), maize (Zea mays L.) and sunflower (Helianthus ... -
Water use, root activity and deep drainage within a perennial legume-grass pasture: a case study in southern inland Queensland, Australia = Uso de agua, actividad radicular y drenaje profundo en una pastura leguminosa-gramínea perenne: Un estudio de caso en el sur de Queensland, Australia
(CIAT, 2016-09)Water use and depth of water extraction of leucaena (Leucaena leucocephala) and Rhodes grass (Chloris gayana) pasture, irrigated with desalinated coal seam water (a by-product of the coal seam gas industry), were monitored ... -
Water-mediated changes in plant–plant and biological soil crust–plant interactions in a temperate forest ecosystem
(Copernicus Publications, 2019-04-09)In the quest to understand how biotic interactions respond to climate change, one area that remains poorly explored is how interactions involving organisms other than vascular plants will respond. However the interactions ... -
Water: tools and functions to estimate actual evapotranspiración using Land Surface Energy Balance Models in R
(2016-12)The crop water requirement is a key factor in the agricultural process. It is usually estimated throughout actual evapotranspiration (ETa). This parameter is the key to develop irrigation strategies, to improve water use ... -
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 ... -
Web-Based System for the Remote Monitoring and Management of Precision Irrigation: A Case Study in an Arid Region of Argentina
(MDPI, 2018-11-09)This article presents a description of the design, development, and implementation of web-based software and dedicated hardware which allows for the remote monitoring and control of a drip irrigation system. The hardware ... -
Weed Communities in Semiarid Rainfed Croplands of Central Argentina: Comparison between Corn (Zea mays) and Soybean (Glycine max) Crops
(2018-05)The semiarid Espinal in central Argentina, being recently transformed from natural semiarid grasslands into agriculture, represents an interesting scenario to understand the early stages of weed community assembly and its ... -
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 ... -
What do domestic livestock eat in northern Patagonian rangelands?
(CSIRO Publishing, 2013-02)The Patagonian rangelands are dominated by steppes interspersed with meadows (locally called mallines), which are small but permanently humid areas, characterised by high spring–summer quality and productivity of grasses ... -
What do we talk about when we talk about Social-Ecological Systems? A Literature Review
(2018-08-20)In the last decade, probably in response to global changes and the environmental crisis, the use of the term “social-ecological system” (SES) in scientific literature has grown. This is certainly a sign that the need and ... -
What Factors Control the Crude Protein Content Variation of a Basaltic “Campos” Native Grassland of South America?
(MDPI, 2022-08)Native grasslands are the main source of food for livestock in the Campos region of South America. These forage resources are heterogeneous in species composition, grazing management, and soil fertility within a context ... -
What is hot in tree rings? The wood density of surviving Douglas-firs to the 2003 drought and heat wave
(Elsevier, 2008-08)In a global warming scenario, drought and heat waves like the one that occurred in 2003 in Europe are expected to become more intense and frequent. This extreme climate event strongly affected the hydraulic balance in many ... -
What is meat in Argentina?
(2017-10)Due to its strong cultural significance, the term “meat” in Argentina has been historically associated with beef, despite its wider definition in the Argentine Food Code. Only by the end of the last century did other meats ... -
