Abundance and spatial patterning of coexisting perennial grasses in grazed shrublands of the Patagonian Monte
(Academic Press Ltd - Elsevier Science Ltd, 2007-07)
We analysed the density, bunch size, and spatial patterning in relation to the shrubby matrix of the three dominant perennial grasses of the Patagonian Monte with different functional traits related to resource ...
Livestock Effects on Genetic Variation of Creosote Bushes in Patagonian Rangelands
(Cambridge University Press, 2019-03)
Genetic diversity is the raw material for species' persistence over time, providing the potential to survive stochastic events, as well as climate and/or human-induced environmental changes. Biodiversity in dry rangelands ...
Sheep spatial grazing strategies at the arid Patagonian Monte, Argentina
(Society for Range Management, 2008)
Relationship between plant nitrogen conservation strategies and the dynamics of soil nitrogen in the arid Patagonian Monte, Argentina
(Springer, 2003-08)
During three consecutive years with contrasting precipitation, we analysed the relationship between strategies of N conservation in the dominant plant functional groups (perennial grasses and evergreen shrubs) of the ...
Neotropical austral migrant landbirds: Population trends and habitat use in the Central Monte Desert, Argentina
(Oxford University Press, 2008-12)
We studied density changes of two groups of Neotropical austral migrant landbirds - the South American temperate-tropical (SATT) and cold-temperate (SACT) migratory systems - in the main habitat types of the central Monte ...
Radiation use efficiency of the herbaceous layer of dry Chaco shrublands and woodlands: Spatial and temporal patterns
(Wiley, 2022-03)
Aims: Monitoring rangeland above-ground net primary production (ANPP) requires information on the variation of radiation use efficiency (RUE). We studied the spatial and temporal variations of RUE of the herbaceous layer ...
Does sheep selectivity along grazing paths negatively affect biological crusts and soil seed banks in arid shrublands? A case study in the Patagonian Monte, Argentina
(Academic Press Ltd - Elsevier Science Ltd, 2011-08)
Domestic animals potentially affect the reproductive output of plants by direct removal of aboveground plant parts but also could alter the structure and fertility of the upper soil and the integrity of biological crusts ...
Carbon storage, community structure and canopy cover: A comparison along a precipitation gradient
(Elsevier Science, 2011-10)
Protected areas play a significant role in carbon storage in arid and semi-arid land. In the central region of Argentina, there are three nature reserves located along a West to East rainfall gradient between two different ...
