(Universidad de Chile, 2020-04)Las histonas, proteínas conocidas por compactar el ADN y formar la cromatina en células eucariontes, tienen además la función de regular procesos de expresión génica, debido a que son susceptibles a modificaciones ...
-
(American Geophysical Union, 2020)Understanding and characterizing the spatial distribution of snow are critical to represent the energy balance and runoff production in mountain environments. In this study, we investigate the interannual and seasonal ...
-
(2001-06-15)Altiplano, a semiarid, high-level plateau entrenched in the central Andes. On the interannual timescale, Altiplano rainfall exhibits pronounced fluctuations between drought and very wet conditions, with subsequent impacts ...
