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 ...
Responses of vegetation to different land-use histories involving grazing and fire in the North-east Patagonian Monte, Argentina
(Australian Rangeland Society, 2013-06)
In arid and semiarid lands around the world, vegetation is distributed in patches within a bare soil matrix. Vegetation in the North-east Patagonian Monte, Argentina is a shrubland steppe, and patches are dominated by ...
Sustainable grazing management in rangelands: Over a century searching for a silver bullet
(Elsevier Science, 2019-11-01)
Rangelands represent 91% of the surface devoted to livestock production and a high proportion of them are exposed to some sort of degradation. Considerable research interest has been centered in the effect of grazing ...
SNP discovery for QTL associated with grazing distribution in Angus cattle using RNA-Seq.
(Amer Soc Animal Science, 2017-08-01)
Grazing increases below-ground biomass and net primary production in a temperate grassland
(Springer, 2015-07)
Background and aims: Grazing can affect the stock and flow of C between above and below-ground vegetation layers. Components of below-ground stratum are one of the less studied. The goals of this research were: 1) to ...
The impact of livestock grazing on the spatial pattern of vegetation in north-eastern Patagonia, Argentina
(Taylor & Francis Ltd, 2018-05)
Background: The occurrence of shrub patches, alternating with either bare soil or low herbaceous cover, is a common feature in arid and semi-arid shrublands throughout the world. This patchy pattern of vegetation may result ...
Changes in vegetation and in the organic fraction soil related with grazing and fire histories in the Patagonian Monte, Argentina
(Nova Science Publishers, 2015)
In terrestrial ecosystems the vegetation and soil co-evoluted in response to some disturbance. In arid and semi-arid lands around the world vegetation is distributed in patches within a bare-soil matrix. Such vegetation ...
Effect of grazing and drought on seed bank in semiarid patchy rangelands of northern patagonia, Argentina
(University of Chicago Press, 2019-03-28)
Premise of research. The soil seed bank (SSB) plays a critical role in vegetation regeneration after stress and/or disturbance events. Here, we analyzed how drought and grazing influence the SSB of shrub patches and ...
Grazing increases evapotranspiration without the cost of lowering soil water storages in arid ecosystems
(John Wiley & Sons Inc, 2017-09)
Grazing is the predominant land use practice in arid environments; however, there are relatively few studies of grazing effects on ecosystem functioning. We assessed the impact of grazing on soil moisture, evapotranspiration ...
