Top: [Mg/Fe] vs. [Fe/H]. Middle: [Ca/Fe] vs. [Fe/H]. Bottom: [Ti/Fe] vs. [Fe/H]. Legend: red triangles show the alpha abundances estimated for NGC 1313-379 (this work); red squares display the measurements for NGC 1705-1; red crosses and black exes present MW disc abundances from Reddy et al. (2003, 2006), respectively; black open circles are MW disc abundances from Bensby et al. (2005); blue squares and stars belong to LMC bar and inner disc abundances presented by Van der Swaelmen et al. (2013); yellow pentagons belong to abundances for LMC young star clusters by Colucci et al. (2012); green circles are abundance measurements from GCs in both the MW and M 31 (Colucci et al. 2009; Cameron 2009).
