Degradation and recovery processes in semi-arid patchy rangelands of northern Patagonia, Argentina
(Wiley, 2013-08)
Vegetation in many arid and semiarid shrublands is frequently arranged in patches with high plant-cover (shrub patches) interspersed in a low-cover herbaceous matrix (inter-shrub areas). We hypothesized that (a) livestock ...
Diet selection by goats on a semi-arid shrubland in central Argentina
(Asociación Argentina de Ecología, 2000-06)
The objective of this study was to determine diet selection by goats on a semi-arid shrubland in the central part of Argentina. Ten goats grazed on a pasture for 10-days periods in winter, spring, and summer. The botanical ...
Fire effects on the soil seed bank and post-fire resilience of a semi-arid shrubland in central Argentina
(Wiley Blackwell Publishing, Inc, 2018-02)
Soil seed bank is an important source of resilience of plant communities who suffered disturbances. We analysed the effect of an intense fire in the soil seed bank of a semi-arid shrubland of Córdoba Argentina. We asked ...
Goat preference for Prosopis caldenia and Prosopis flexuosa
(Elsevier, 2001-02)
Prosopis caldenia and P. flexuosa are native woody plants in central Argentina. Circumstantial observations have shown that goats consistently select the first species and avoid the latter. The present study was designed ...
Spatial and temporal patterns of herbaceous primary production in semi-arid shrublands: a remote sensing approach
(Wiley Blackwell Publishing, Inc, 2016-07)
Questions: Can herbaceous above-ground net primary production (ANPP) be estimated from remote sensing when woody and herbaceous plants are intermingled? How does herbaceous ANPP change in space and time in an ecosystem ...
Plant cover as an estimator of above-ground biomass in semi-arid woody vegetation in Northeast Patagonia, Argentina
(Science Press, 2021-09)
The quantification of carbon storage in vegetation biomass is a crucial factor in the estimation and mitigation of CO2 emissions. Globally, arid and semi-arid regions are considered an important carbon sink. However, they ...
Plant community resilience in the face of fire: experimental evidence from a semi‐arid shrubland
(Wiley Blackwell Publishing, Inc, 2016-02)
The ability of communities or ecosystems to recover their structure and function after a disturbance is known as resilience. According to different views, resilience can be influenced by the resource-use strategies of the ...
Rainfall, microhabitat, and small mammals influence the abundance and distribution of soil microorganisms in a Chilean semi-arid shrubland
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2016)
Patterns in rainfall and soil water availability are considered to be the main drivers governing arid and semiarid ecosystems. While the mechanisms by which water limits aboveground net primary production has been widely ...
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 ...
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 ...
