These bioclimatic models, also known as ecological niche models or climate envelope models, [55] are developed with the aim to predict changes in species ranges and are an essential tool for the development of effective management strategies and actions (e.g. eradication of invasive species and prevention of introduction [56]) to reduce the ...
