Germination requirements of two sheep-preferred grasses (Hordeum comosum and Koeleria vurilochensis var. patagonica) from semiarid Patagonian steppes
(Elsevier, 2012-03)Grazing by domestic exotic herbivores on native vegetation in Patagonian steppes has led to the deterioration of forage resources, where grasses are replaced by shrubs, and preferred grasses by non-preferred ones. Therefore, ... -
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 ... -
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. ...
