Plant litter decomposition in a semi-arid rangeland of Argentina: species and defoliation effects
(Australian Rangeland Society, 2019-09)
Plant litter decomposition is critical for terrestrial ecosystem productivity. Poa ligularis Nees ex Steud and Nassella tenuis (Phil.) Barkworth are native, desirable perennial grasses in central Argentina’s rangelands. ...
Archetypal temporal dynamics of arid and semi-arid rangelands
(Elsevier, 2021-03)
The way in which temporal dynamics structure ecological systems under the influence of a changing environment has long interested ecologists. Tackling the hierarchical structure of complex temporal patterns is a necessary ...
Precipitation is the key determinant of topsoil δ15N values in southern Patagonia's semiarid rangelands
(Soil Science Society of AmericaEstados Unidos, 2022-02-11)
Nitrogen (N) cycling in rangeland soils could potentially be controlled by water supply, stocking rates, or a range of other variables, such as ecosystem N stocks. To gauge the relative importance and elucidate possible ...
Can livestock and fires convert the sub-tropical mountain rangelands of central Argentina into a rocky desert?
(Australian Rangeland Soc, 2013-03)
Soil erosion, as a result of livestock grazing, has been widely reported for arid and semi-arid ecosystems, but information is lacking in more mesic ecosystems where erosion is generally studied in relation to agriculture. ...
An exploration of direct and indirect drivers of herbivore reproductive performance in arid and semi arid rangelands by means of structural equation models
(Elsevier, 2012-06)
Climate variability affects both animal and plant populations. Understanding how this variability is modulated by topography, vegetation and population densities and how this impact on ungulate demography is an important ...
Combined effects of leaf litter and soil microsite on decomposition process in arid rangelands
(Elsevier, 2013-01)
The objective of this study was to analyze the combined effects of leaf litter quality and soil properties on litter decomposition and soil nitrogen (N) mineralization at conserved (C) and disturbed by sheep grazing (D) ...
Monitoring drylands: The MARAS system
(Elsevier, 2018-11-09)
MARAS (Monitoring of Arid and Semiarid Regions) consists of 379 ground monitors in Patagonia, a 624.500 km2 semiarid area of southern Argentina and Chile. The objective of this paper was to describe the system and analyze ...
Production and turnover rates of shallow fine roots in rangelands of the Patagonian Monte, Argentina
(Springer Tokyo, 2012-01)
Selective sheep grazing in arid rangelands induces a decrease in total cover and grass cover and an increase in the dominance of shrubs. Both life forms differ in aboveground and belowground traits. We hypothesized that ...
Foraging behavior of Argentine Criollo and Angus cows grazing semi-desert rangelands in the Arid Gran Chaco region of Argentina
(Elsevier, 2022-11)
We monitored grazing behavior and habitat selection of Argentine Criollo (AC), South American heritage cattle breed, and Angus (AA) cows during summer and winter of 2016 (wetter year) and 2017 (drier year) at a site in La ...
