  abstract = {{O}restias ascotanensis is a killifish endemic to the {A}scotan salt pan in the {C}hilean {A}ltiplano, where it inhabits 12 springs with different degrees of isolation. {T}his species is a suitable model for studying the effect of serial geographical isolations on the differentiation process among populations. {T}he present study examines the genetic variation and structure of the species using mitochondrial {DNA} control region sequences and eight microsatellite loci, analyzing populations across its distribution range. {T}he evaluation of genetic variation revealed high levels of diversity within the species. {T}he genetic structure analysis showed the existence of four differentiated groups: two groups were formed by the springs located in the northern and southern extremes of the salt pan and two groups were found in the centre of the salt pan. {T}he latter two groups were formed by several springs, most likely as a consequence of the {S}outh {A}merican summer monsoon that could connect them and allow gene flow. {T}he patterns of genetic differentiation appear to be determined based on the physical isolation of the populations. {T}his isolation may be the result of a combination of factors, including geographical distance, a historical decrease in water levels and altitude differences in the springs of the salt pan. {T}herefore, this system is a rare example in which hydrological factors can explain genetic differentiation on a very small scale.},
