Abstract

The study aimed to evaluate the space-time distribution of Thunbergia alata Sims (Susanita) in the inter-Andean region of Ecuador under climate change scenarios and futures projections. A mixed methodological approach was applied, integrating validated occurrence records (1,407 observations), bioclimatic variables selected through Pearson correlation analysis, and ecological niche modeling with MaxEnt, using open-source data (GBIF, iNaturalist) and climate projections from MIROC5 and HADGEM2-ES models under RCP 2.6 and 8.5 scenarios. Results showed high predictive performance (AUC > 0.90), confirming the reliability of the model to estimate environmental suitability. Currently, distribution is concentrated in Pichincha, Loja, and Azuay; however, projections indicate expansion towards Imbabura, Cotopaxi, Chimborazo, and Tungurahua, driven by increasing mean temperatures and reduced thermal seasonality. It is concluded that climate change acts as a facilitator of invasion, increasing ecological risk in Andean ecosystems with high biodiversity. The generated information provides a scientific basis to guide early monitoring, ecological restoration, and territorial management, aiming to prevent negative impacts on native biodiversity.

Keywords: climate change, inter- Andean region, invasive species, MaxEnt modeling, Thunbergia alata.
