Self‐regeneration of hairy vetch (Vicia villosa Roth) as affected by seedling density and soil tillage method in a semi‐arid agroecosystem
(2017-09)Vicia villosa Roth is a forage legume with the capability for biological N fixation and natural reseeding, which could contribute to sustainability in semi‐arid regions. This study aimed to determine (i) the relationship ... -
Soil respiration in Patagonian semiarid grasslands under contrasting environmental and use conditions
(Elsevier, 2015-08)Grasslands comprise 85% of Southern Patagonia land area and play a critical role in the global carbon cycle. We evaluated seasonal dynamics to identify differences in soil respiration rates between contrasting grasslands ... -
Spatial and temporal patterns of herbaceous primary production in semi‐arid shrublands: a remote sensing approach
(2016-07)Questions: Can herbaceous above‐ground net primary production (ANPP) be estimated from remote sensing when woody and herbaceous plants are intermingled? How does herbaceous ANPP change in space and time in an ecosystem ... -
Sustainable livelihoods approach through the lens of the State-ans-Transition Model in semi-arid pastoral systems
(2016)Enfrentar desafíos complejos a nivel mundial en relación con el desarrollo sostenible y la gestión ambiental requiere marcos aplicados para comprender y gestionar el cambio en sistemas sociales y ecológicos complejos. A ... -
Sustentabilidad de sistemas ganaderos extensivos ovinos en zonas áridas y semiáridas en Patagonia
(Universidad Nacional del Sur, 2015)Desde hace más de un siglo la Patagonia es un lugar donde cobija los sistemas ganaderos extensivos ovinos explotados mediante los pastizales naturales que escasamente posee la región, sobre todo en las zonas con bajas ... -
Tips ganaderos
(Estación Experimental Agropecuaria La Rioja, INTA, 2019-11)Lo que hoy debe saber el productor ganadero en regiones áridas y semiáridas. -
Use and management of biodiversity by smallholder farmers in semi-arid West Africa
(Elsevier, 2018-09)Strategies that strengthen and use biodiversity are crucial for sustained food production and livelihoods in semiarid West Africa. The objective of this paper was to examine the role of biodiversity in sustaining diverse ... -
Using APAR to Predict Aboveground Plant Productivity in Semi-Arid Rangelands: Spatial and Temporal Relationships Differ
(2018)Monitoring of aboveground net primary production (ANPP) is critical for effective management of rangeland ecosystems but is problematic due to the vast extent of rangelands globally, and the high costs of ground-based ... -
Valeriana gaimanensis (Valerianaceae nom. conserv.), a New Species from the Patagonian Semi-Arid Desert, Argentina
(American Society of Plant Taxonomists, 2016-02)Valeriana gaimanensis, a new species from Argentinean Patagonia, is described and illustrated. The new species belongs to the subgenus Valeriana and is apparently endemic to the Extra-Andean Patagonia region, where it grows ... -
Valores umbrales de algunos indicadores de calidad de suelos en molisoles de la región semiárida pampeana = Threshold values of some soil quality indicators in the semiarid pampas
(Asociación Argentina de la Ciencia del Suelo, 2016)Los objetivos del trabajo fueron evaluar los efectos de variaciones en los contenidos de materia orgánica sobre propiedades edáficas e identificar indicadores simples y de fácil determinación que sirvan para caracterizar ... -
Vegetative growth, yield, and crop water productivity response to different irrigation regimes in high density walnut orchards (Juglans regia L.) in a semi-arid environment in Argentina
(Elsevier, 2022-12)The area dedicated to walnut orchards has recently expanded in central-western Argentina. Nevertheless, studies on crop water demand are scarce and fundamental in semi-arid environments. This work aims to evaluate the ... -
Vicia villosa ssp. villosa Roth field emergence model in a semiarid agroecosystem
(2018-03)Hairy vetch (Vicia villosa Roth) is a winter annual legume cultivated for pasture and hay with the capability for natural reseeding. Vicia villosa increases N concentrations in the soil, thus contributing to the sustainability ...
