Abstract
Invasive species and climate change are critical global challenges posing significant threats to biodiversity, ecosystems, and economies. This study analyzed the ecological niche dynamics and potential habitat overlap of two invasive species, Elaeagnus angustifolia (Russian olive, RO) and Anoplophora glabripennis (Asian longhorned beetle, ALB), under diverse climate scenarios. Through an ensemble modeling approach, global habitat suitability for both species was projected, climatic responses evaluated, and niche shifts were analyzed using wit COUE and NDH frameworks. The results reveal that climatic variables, including isothermality and temperature seasonality, strongly influence the distributions of ALB and RO. The adaptability of RO was evident in regions with low isothermality, whereas its distribution was constrained by excessive precipitation. The distribution of ALB was influenced by its hosts, and exhibits adaptability to high-altitude habitat. Under climate change, it is anticipated that the suitability habitat for RO would undergo a future reduction, whereas the suitability habitat for ALB was predicted to expand. The greatest habitat overlap occurs in Europe, with moderate overlap observed in North America and Asia, alongside evidence of niche convergence in invaded regions. The ecological niche of RO remains stable, whereas ALB demonstrates considerable niche expansion and adaptive potential within its invasive range. Our findings emphasize the critical necessity of global-scale monitoring and adaptive management strategies to mitigate the compounded effects of biological invasions and climate change.
