"In this thesis I present observations and analyses addressed to understand the individual evolution\r\nof dwarf galaxies and the interdependency with their local environment. My study focuses\r\non the Fornax dwarf spheroidal galaxy, which is the most massive galaxy of its type in the Local\r\nGroup, hosting stars with a broad range in age and metallicity. Additionally, it is the only intact\r\ndwarf spheroidal with an own globular cluster system. Therefore, it provides a superb laboratory to\r\ngain insights about the formation and chemical enrichment processes of baryonic matter in Galactic\r\nhalos. In particular, I have used individual alpha-element abundances obtained from high-resolution\r\nspectra to characterize, for the first time, the chemical evolution of Fornax over its entire age and\r\nfind a surprisingly low early chemical enrichment efficiency with respect to other dwarf galaxies.\r\nComparison with chemical evolution models show that Fornax must have experienced a systematically\r\nincreasing star formation efficiency with time in order to bring the observations in agreement\r\nwith the model predictions. One emerging evolutionary scenario is that Fornax experienced major\r\naccretion events in the past, so that its current properties are not indicative of the chemical enrichment\r\nenvironment at ancient times. A similar chemical analysis for the globular cluster H4 and\r\nnearby field stars in Fornax reveals, that H4 is depleted in all analyzed alpha-elements and falls on\r\ntop of the observed field star [alpha/Fe] sequence, while its abundance pattern disagrees with the properties\r\nof Milky Way halo field stars and clusters. Thus, I propose a chemical enrichment coupling\r\nof the globular cluster population and field stars in Fornax. This finding provides tight constraints\r\non the origin of alpha-depleted globular clusters in the Milky Way and will enable the chemical enrichment\r\ncharacterization of distant galaxies from integrated-light cluster analysis where field stars\r\nare too faint for detailed chemical analysis."^^ .
