Reassessing the role of grazing lands in carbon-balance estimations: Meta-analysis and review
(Elsevier, 2019-01)
Assuming a steady state between carbon (C) gains and losses, greenhouse gases (GHG) inventories that follow a widely used simplified procedure (IPCC Tier 1) tend to underestimate the capacity of soils in grazing-land to ...
Quantitative assessment of shrub-grass mosaic development in grazed shrublands: An example in the Patagonian Monte (Argentina)
(Academic Press Ltd - Elsevier Science Ltd, 2010-08)
Grazing alters the spatial structure of shrubs and perennial grasses in desert shrub communities. The resulting spatial distribution of shrub-grass patches constitutes a sensitive indicator of the integrated result of ...
Shrub-dwelling arthropod assemblages respond differently to grazing disturbance in the southern Monte, Argentina
(Elsevier Ltd., 2021-05)
Grazing disturbance affects an extensive area of the Monte desert (Argentina). Arthropods are the main faunistic component of the Monte and play key roles in ecosystem processes. The aim of this study was to analyse the ...
Growth, encystment and survival of Acanthamoeba castellanii grazing on different bacteria
(WILEY-BLACKWELL, 2008)
Free-living amoebae of the genus Acanthamoeba are widely distributed in soil and water collections, where trophozoites (vegetative, multiplicative stages) feed mainly by phagocytosis and thus control bacterial populations ...
Effects of differential grazing on decomposition rate and nitrogen availability in a productive mountain grassland
(Springer, 2013-08)
Background and Aims Grazing may influence nutrient cycling in several ways. In productive mountain grasslands of central Argentina cattle grazing maintain a mosaic of different vegetation patches: lawns, grazed intensively ...
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. ...
The effect of grazing on granivory patterns in the temperate Monte Desert, Argentina
(Gauthier-Villars/Editions Elsevier, 2006-06)
Structural variations result in a marked heterogeneity of processes in arid environments. Disturbances have noticeable impacts on ecosystems, and a solid way of assessing their effect is to analyze how ecological processes ...
Presence, abundance and bacterivory of the mixotrophic algae Pseudopedinella (Dictyochophyceae) in freshwater environments
(Inter-Research, 2016-02)
The genus Pseudopedinella has been described as mixotrophic; however, ecological information about this algal stramenopile (Heterokonta) is unclear. We investigate the environmental conditions that determine the presence, ...
