Regional productivity mediates the effects of grazing disturbance on plant cover and patch-size distribution in arid and semi-arid communities
(Wiley Blackwell Publishing, Inc, 2018-08)
Patch‐size distribution and plant cover are strongly associated to arid ecosystem functioning and may be a warning signal for the onset of desertification under changes in disturbance regimes. However, the interaction ...
Nutritive value and physical characteristics of Xaraes palisadegrass as affected by grazing strategy
(SOUTH AFRICAN JOURNAL OF ANIMAL SCIENCES, 2010)
The aim of this study was to ascertain whether the defoliation frequency based on a fixed rest period would generate variable sward structural and physiological conditions at each subsequent grazing event. The relative ...
Aridity and grazing as convergent selective forces: an experiment with an Arid Chaco bunchgrass
(Wiley, 2010-10)
It has been proposed that aridity and grazing are convergent selective forces: each one selects for traits conferring resistance to both. However, this conceptual model has not yet been experimentally validated. The aim ...
Anthelmintic resistance in grazing beef cattle in central and northeastern areas of Argentina — An update
(Elsevier Science, 2017-08)
The presence of anthelmintic resistance in Argentina has experienced a marked increase in cattle, with numerous reports showing levels of resistance of different parasite genera to different chemical groups. The aim of ...
Grass recruitment constraints along a grazing gradient in Patagonia: N-limitation x adult competition trade-off: Grass recruitment and grazing in Patagonia
(Academic Press Ltd - Elsevier Science Ltd, 2021-06)
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 ...
Changes in plant cover and functional traits induced by grazing in the arid Patagonian Monte
(Elsevier Masson, 2013-06)
Grazing disturbance may affect the structure and functioning of arid rangelands. We analyzed the changes in plant cover and plant functional traits (plant height, SLA, N in green leaves) at the community, morphotype and ...
Topsoil compaction and recovery in integrated no-tilled crop–livestock systems of Argentina
(Elsevier Science, 2015-11)
Cattle trampling during grazing of crop residue may cause physical soil damage that may be repaired when animals are excluded. Understanding the interplay between soil deterioration and natural recovery of the soil physical ...
Can grazing response of herbaceous plants be predicted from simple vegetative traits?
(Wiley Blackwell Publishing, Inc, 2001-07)
Range manafement is based on the response of plant species and communities to grazing intensity. The identification of easily measured plant functional traits that consistently predict grazin response in a wide spectrum ...
Aridity and grazing as convergent selective forces: An experiment with an Arid Chaco bunchgrass
(Ecological Society of America, 2010-10)
It has been proposed that aridity and grazing are convergent selective forces: each one selects for traits conferring resistance to both. However, this conceptual model has not yet been experimentally validated. The aim ...
