Evidence on the response of Patagonian forage grasses to the mulching effect of recent tephra deposits in Argentina
(Taylor & Francis, 2017-10)
In Patagonia, arid and semiarid lands are being affected both by inappropriate management practices, which are leading to degradation, and by volcanic activity, whose effects are still unclear. This study aimed to test ...
Micorrización y fertilización de plantines de vivero de Pappostipa speciosa (Trin. y Rupr.) Romasch destinados a proyectos de rehabilitación ecológica
La calidad de las plantas de vivero destinadas a restauración ecológica ha sido reconocida como clave para la supervivencia en campo y consecuentemente la recuperación de sitios degradados. En este trabajo se evaluó el ...

Effect of fire on recruitment of two dominant perennial grasses with different palatability from semi-arid grasslands of NW Patagonia (Argentina)
(Springer, 2012-03)
Fire is a non-selective disturbance that impacts equally plant species that could be selected differentially by livestock. Post-fire recruitment dynamics is an important ecological process that has been barely studied in ...
Effect of drought on morphological and functional traits of Poa ligularis and Pappostipa speciosa, native perennial grasses with wide distribution in Patagonian rangelands, Argentina
(Csiro Publishing, 2013-07)
Poa ligularis Nees. Ap. Steudel and Pappostipa speciosa (Trin. et Rupr.) Romaschenko are dominant perennial grasses in the arid Patagonian rangelands of Argentina. Both species are exposed to periods of water shortage ...
Early competition between the exotic herb Rumex acetosella and two native tussock grasses with different palatability and water stress tolerance
(Elsevier, 2014-07)
Semiarid grasslands in NW Patagonia (Argentina) are dominated by Festuca pallescens and Pappostipa speciosa, two native tussock grasses that differ in water stress tolerance and in palatability to livestock. Both species ...
Comprehensive and quantitative profiling of lipid molecular species by LC-ESI-MS/MS of four native species from semiarid Patagonian Monte
(Elsevier Masson, 2019-11)
The maintenance of lipid and fatty acids unsaturated composition has been described as one of the mechanisms associated to drought tolerance, but research about the lipid profile in native plants of semiarid environment ...
Phenotypic plasticity as an index of drought tolerance in three Patagonian steppe grasses
(Oxford University Press, 2012-09)
Background and AimsDespite general agreement regarding the adaptive importance of plasticity, evidence for the role of environmental resource availability in plants is scarce. In arid and semi-arid environments, the ...
Abscisic acid and its metabolites are involved in drought tolerance in four native species of Patagonian semiarid shrublands (Argentina)
(Csiro Publishing, 2018-12)
Drought is the main stress that affects growth of native species of Patagonian Monte. Physiological and biochemical traits with functional roles in adaptation to drought are still scarce in native species. The aim of this ...
