AB European vipers (Vipera) show parapatric distributions as result of distinct evolutionary trajectories andspecific ecological requirements. Competitive interactions among species at range margins play an importantrole in the sustainment of distributional patterns. Taking into account the competition between species in aheterogeneous climate along their distribution areas, three biogeographical cases are predicted to happen: 1)autoecological segregation, when a low favorable climate is stronger than biological interactions; 2) sympatriccoexistence, when an optimal climate for both species provides high abundance of resources, minimizing theeffect of competitive interactions; and 3) sinecological segregation, when in sub-optimal areas, one species,better adapted to this conditions, could exclude the other by competition. Fuzzy logic distribution modelsprovide a useful framework to analyze and identify these interactions. Using a presence/absence matrix for fivewestern vipers (V. aspis, V. berus, V. lataste and V. seoanei) and a set of climate variables at ~10x10 kmresolution, we studied species favorability for current and future climate scenarios. Regions of overlap betweenspecies pairs were analyzed to identify the three biogeographical cases in both periods of time. Resultsemphasize the generalist character of V. aspis, with a predicted range largest than the currently observed, and thestrong competitive character of V. berus, V. latastei and V. seoanei at range margins, which might be limiting theexpansion of the former species. Despite a high uncertainty in our predictions, future favorable areas arerestricted to coastal and mountain regions, which is translated into important changes in species interactions.
