Abstract: We modelled the distribution of two genetically differentiated forms of the Golden-striped salamander, Chioglossa lusitanica, in Portugal with the help of a geographical information system. Models were derived with and without the assumption that the contact zone between the forms would be associated with the Mondego river valley and with and without the statistical Bonferroni correction. The model fit was high and ranged from kappa = 0.81-0.99. The southern form appears to live under harsher (but still tolerated) environmental conditions than the northern form (low precipitation, low air humidity, low summer temperatures, a high number of frost months, low NOVI vegetation index) and can be viewed as a mountain form. This is in line with the observation that the southern form has shorter extremities than the northern one.
