Effect of defoliation frequency on Rytidosperma virescens plants and arbuscular mycorrhizal fungi colonization
(Elsevier, 2022-06-09)
Rangelands provide different ecosystem services to satisfy human needs. Although grazing management in southern Patagonia is mostly characterized by extensive continuous grazing, rotational grazing management may improve ...
Rangeland grazing management in Argentine Patagonia
(IJAB. Friends science publishers, 2020-08-31)
Stocking rate adjustment in grazing management is recommended as a management tool to sustain productivity and improve soil health of permanent grassland ecosystems. The aim of this project was to assess the effect of ...
Long-term grazing negatively affects nitrogen dynamics in Northern Patagonian wet meadows
(Elsevier, 2014-10)
Wet meadows are seasonally saturated wetlands that can develop in arid and semi-arid areas. In the semi-arid region of North Patagonia, Argentina wet meadows are islands of high net primary productivity surrounded by low ...
The role of grazing intensity and preference on grass-fungal endophyte symbiosis in a Patagonian steppe
(Academic Press Ltd - Elsevier Science Ltd, 2016-11)
The symbiosis between cool-season grasses and fungi of the genus Epichloë is widespread, but highly variable in natural ecosystems. Biotic and abiotic controls underlying its distribution patterns have been difficult to ...
Grazing time and milk production of crossbred cows in a rotational area of Elephant grass and Tanzania grass
(2004-11-01)
This study was carried out in January of two consecutive years. The objective was to evaluate the grazing time, the grazing rate and the milk production of crossbred cows, managed in two rotational grazing areas, one with ...
Long-term impact of domestic ungulates versus the local controls of the litter decomposition process in arid steppes
(Springer, 2021-08)
Aims: Soil processes in arid ecosystems are strongly controlled by resource scarcity. Grazing intensification can induce changes in ecosystem processes through multiple pathways, adding new constraints to those of local ...
