Remotely‐sensed primary productivity shows that domestic and native herbivores combined are overgrazing Patagonia
(Wiley; British Ecological Society, 2019-04)1.Carrying capacity is the maximum animal density an area can sustain without deterioration of its resources. Overgrazing has degraded Patagonia, but sheep stocks decreased and gave way to mixed systems with cattle, goats ... -
Soil erodibility and quality of volcanic soils as affected by pine plantations in degraded rangelands of NW Patagonia
(2016-08)NW Patagonia in Argentina has high potential for planting fast-growing exotic conifers, supported by its volcanic soils. Nonetheless, many aspects related to the effects of pine plantations on soil are still unknown. We ... -
Soil physical changes after conversion of woodlands to pastures in dry Chaco rangelands (Argentina)
(2017-03)The conversion of dry woody rangelands into pastures can alter key soil physical properties that regulate ecosystem water circulation and storage. Based on three paired stands of native woodlands and pastures established ... -
South American Dry Chaco rangelands: Positive effects of cattle trampling and transit on ecohydrological functioning
(Wiley, 2022-12)Livestock production in drylands requires consideration of the ecological applications of ecohydrological redistribution of water. Intensive cattle trampling and the associated increase of surface runoff are common concerns ... -
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 ... -
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 ... -
Vegetation type mapping in Southern Patagonia and its relationship with ecosystem services, soil carbon stock, and biodiversity
(MDPI, 2024-02-29)Vegetation Type (VT) mapping using Optical Earth observation data is essential for the management and conservation of natural resources, as well as for the evaluation of the supply of provisioning ecosystem services (ESs), ... -
Wild halophytic species as forage sources: key aspects for plant breeding
(Wiley; British Grassland Society; European Grassland Federation, 2019-02-20)The use of wild halophytic species as forage resources in saline environments has gained increasing attention. Argentina ranks third in area of saline soils in the world, with a third of its territory showing various degrees ...
