Phylogenetic relationships and intraspecific diversity of a North Patagonian Fescue: evidence of differentiation and interspecific introgression at peripheral populations
(Springer, 2018-03-16)
Peripheral sites usually offer suboptimal conditions for species with wide distributions, where expression of phenotypic variability and potential interspecific hybridization might be enhanced. The Patagonian steppe, the ...
Diferencias fenológicas en poblaciones seleccionadas de Festuca pallescens, pastura nativa PatagónicaPhenological differences among selected populations of Festuca pallescens, native Patagonian pasture
(Asociación Argentina de Producción Animal, 2022-11)
En la Patagonia, los pastizales naturales son utilizados como fuente de alimento en la producción extensiva de animales domésticos. Ampliar el conocimiento sobre el comportamiento estacional de las pasturas de especies ...
Seed responses to temperature indicate different germination strategies among Festuca pallescens populations from semi-arid environments in North Patagonia
(Elsevier Science, 2019-07)
Seed germination is one of the earliest phenotypes expressed by plants, and the accuracy to germinate in the correct time and place is essential for plant population fitness. Cues that regulate germination have been ...

¿Puede el peletizado y el uso de hidrogel mejorar la implantación de Festuca pallescens en condiciones naturales? Comunicación
(Asociación Argentina de Producción Animal, 2022-11)
La alta presión de pastoreo, junto con el cambio climático, están provocando el retroceso de algunos pastizales en zonas productivas de la Patagonia. Esto es lo que ocurre con los pastizales dominados por Festuca pallescens ...
Local adaptation along a sharp rainfall gradient occurs in a native Patagonian grass, Festuca pallescens, regardless of extensive gene flow
(Elsevier, 2020-03)
Increasing global aridity combined with changing environmental conditions might cause irreparable alterations in arid and semiarid ecosystems. Knowledge of within-species genetic diversity and adaptive responses, especially ...
Germination response to water availability in populations of Festuca pallescens along a Patagonian rainfall gradient based on hydrotime model parameters
(Springer Nature, 2021-05)
Sensitivity to water availability is a key physiological trait for grassland species located in arid and semiarid environments, where successful germination is closely related to rainfall dynamics. Festuca pallescens ...
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 ...
