Effects of dietary supplementation on vegetation cover and its defoliation by sheep in extensive husbandry
(Elsevier, 2022-06-06)Dietary supplementation is one of the most used strategies to reduce the effect of environmental fluctuations in arid and semi-arid environments. We evaluated changes in vegetation and in patterns of animal defoliation as ... -
Trends in ANPP response to temperature in wetland meadows across a subcontinental gradient in Patagonia
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-06-17)Due to ongoing global warming, seasonal patterns of aboveground net primary production (ANPP) may be altered by temperature trends. Of particular interest is the seasonal association between ANPP and temperature at the ... -
How does grazing affect soil water availability in the Patagonian steppe?
(Elsevier, 2022-06-01)In the Patagonian steppe, grazing may or may not reduce soil water availability: it may increase evaporative losses, because it reduces plant cover, but may decrease transpiration losses because it decreases plant biomass. ... -
Resilient andisols under silvopastoral systems

Role of abiotic factors in nothofagus pumilio forest mortality: the sensitivity of ecotones
(Elsevier, 2021-04-24)The world's forests are being affected by a changing climate. Recently, patches of dead trees have been found in forests of the Patagonian endemic species Nothofagus pumilio, which could not be related to insects or ... -
Grass recruitment constraints along a grazing gradient in Patagonia: N-limitation x adult competition trade-off
(Elsevier, 2021-03-09)We explored the effect of N addition and adult canopy competition on the recruitment of lost preferred species in the Patagonian steppe, where a decelerated N cycling scenario (sensu Ritchie et al., 1998) had been previously ... -
Phytophthora austrocedri in Argentina and co-Inhabiting phytophthoras: roles of anthropogenic and abiotic factors in species distribution and diversity
(MDPI, 2020-11-20)This work reports the first survey of Phytophthora diversity in the forests soils of Andean Patagonia. It also discusses the role of anthropogenic impact on Phytophthora distribution inferred from the findings on Phytophthora ... -
