Implication

Modeling study uncovers transient movement barriers for 294 terrestrial mammals, indicating that multi-step planning is essential to safeguard climate dispersal corridors.

Key Points

Develop and apply a trajectory-based, multi-step climate adaptive connectivity framework to identify intermediate dispersal pathways and transient movement barriers under projected climate shifts.
Evaluated 294 terrestrial mammal species across four future 20-year time steps (2021–2040, 2041–2060, 2061–2080, 2081–2100) and three emissions scenarios (SSP126, SSP370, SSP585).
Modeled habitat suitability using BioModelos species distribution models to generate conductance surfaces, and simulated dispersal using omnidirectional circuit theory (Omniscape).
Multi-step temporal modeling revealed transient connectivity barriers in central Colombia that repeatedly severed climate-tracking routes but were missed by endpoint-only assessments.
Higher emissions scenarios caused well-connected zones to contract toward the Andes, converting a central corridor connecting the Amazon and Andes from a movement facilitator into a barrier.
