Grazing and ecosystem service delivery in global drylands.
(2022)
Grazing represents the most extensive use of land worldwide. Yet its impacts on ecosystem services remain uncertain because pervasive interactions between grazing pressure, climate, soil properties, and biodiversity may ...
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 ...
Grazing dynamics on a Caribbean reef-building coral
Corals in certain Caribbean coral reef habitats are constantly grazed-on due to the territorial marking behavior of the stoplight parrotfish Sparisoma viride. We studied the grazing dynamics on the Caribbean reefbuilding ...
Grazing pressure interacts with aridity to determine the development and diversity of biological soil crusts in Patagonian rangelands
(John Wiley & Sons Ltd, 2019-10)
Grazing is directly related to land degradation and desertification in global drylands. Grazing impacts on vascular plants, reasonably well-known, depend on its intensity and are modulated by local aridity conditions. ...
Sheep grazing differentially affects the canopy attributes and functional diversity of shrubs and perennial grasses in arid rangelands
(Springer, 2021-01)
We analysed how changes in community attributes promoted by domestic grazing are reflected on functional traits in canopies of shrubs and perennial grasses in rangelands of the Patagonian Monte. We selected four sites ...
Plant interactions balance under biotic and abiotic stressors: The importance of herbivory in semi-arid ecosystems
(Springer, 2020-10)
Biotic and abiotic stressors commonly co-occur in plant communities and influence interactions between plants. However, their combined effects on plant interactions have not been widely studied and are still unclear. Here, ...
Changes in plant cover induced by grazing affect the soluble fraction of soil organic carbon – but not the total pool size in the arid rangelands of Patagonian Monte, Argentina
(10th International Rangeland Congress, 2016)
Soilis the largest organic C (SOC) pool in the biosphere. The size ofthis pool depends on the primary production and SOC residence time which arecontrolled by biome type, climatic conditions and land management.In arid ...
Aquatic plant composition and environmental relationships in grazed Northwest Patagonian wetlands, Argentina
(Elsevier Science Inc, 2014)
Aquatic macrophyte assemblages and environmental features were assessed in 30 wetlands from North- west Patagonia subjected to different intensity of grazing pressure. Species richness was surveyed in wetlands from three ...
