How do species reach the limits of their distribution and what prevents continued expansion beyond these ranges? Exotic plant represent a natural experiment to answer questions. If climate is limiting factor, then one would expect matching between observed range limit for predicted by its climatic niche. there no matching, other factors such as dispersal limitation, competition or facilitation come into play. In this work, eight exotic legume were compared: Acacia dealbata , melanoxylon Cytisus striatus Teline monspessulana Ulex europaeus Lotus corniculatus Trifolium suffocatum Vicia villosa in latitudinal gradient Chile. For estimation (North South), absence/presence data obtained from 30° 43.1° south latitude. limits, GBIF presence used construct global niches, identifying suitable zones (presences) unsuitable (absences). With information, probability models constructed with hierarchical Huisman-Olff-Fresh (HOF) regression, which South) obtained. Our results suggest that have reached edge at northern southern end gradient. The rest not yet across both geographic edges. At gradient, most niche; except whose higher than predicted. Factors are discussed explain discrepancies limits.
