Evidence on the response of Patagonian forage grasses to the mulching effect of recent tephra deposits in Argentina Edwards, Priscila; Varela, Santiago Agustin; Lopez, Dardo Ruben; Willems, Priscila Mabel; Lopez, Aldana; Gyenge, Javier (Taylor & Francis, 2017-08-31)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 ...
Germination response to water availability in populations of Festuca pallescens along a Patagonian rainfall gradient based on hydrotime model parameters Lopez, Aldana Soledad; Lopez, Dardo Ruben; Arana, María Veronica; Battla, Diego; Marchelli, Paula (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 ...
Local adaptation along a sharp rainfall gradient occurs in a native Patagonian grass, Festuca pallescens, regardless of extensive gene flow Lopez, Aldana Soledad; Lopez, Dardo Ruben; Caballe, Gonzalo; Siffredi, Guillermo Lorenzo; Marchelli, Paula (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 ...
Phylogenetic relationships and intraspecific diversity of a North Patagonian Fescue: evidence of differentiation and interspecific introgression at peripheral populations Lopez, Aldana; Azpilicueta, Maria Marta; Lopez, Dardo Ruben; Siffredi, Guillermo Lorenzo; Marchelli, Paula (2018-03)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 ...
Population genetic structure and historical dispersal patterns in the subterranean rodent Ctenomys “chasiquensis” from the southeastern Pampas region, Argentina Mora, Matias Sebastian; Mapelli, Fernando Javier; Lopez, Aldana; Gomez Fernandez, Maria Jimena; Mirol, Patricia Monica; Kittlein, Marcelo Javier (Elsevier, 2016-05)Gene flow plays an essential role in the evolutionary history of the organisms and helps to identify those historical landscape features that most likely had affected the dispersal patterns. In this work, we assess, using ...
Seed responses to temperature indicate different germination strategies among Festuca pallescens populations from semi-arid environments in North Patagonia Lopez, Aldana; Marchelli, Paula; Batlla, Diego; Lopez, Dardo Ruben; Arana, María Veronica (Elsevier, 2019-04)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 ...
