Global climate change effect on AsianMus musculus; Implication from last glacial maximum to the end of the 21stcentury

Abstract

ABSTRACTGlobal climate change poses unprecedented challenges to biodiversity, prompting urgent investigations into its effects on various species. This study focuses onMus musculus, a small rodent species and a crucial indicator of ecosystem health. Spanning from the last glacial maximum to the end of the 21stcentury, employed Species Distribution Models (SDMs) to assess the impacts of climate change onMus musculusand its four subspecies across Asia (M. m musculus,M. m domesticus,M. m castaneus, andM. m bactrianus). The SDMs reveal nuanced responses among subspecies, withM. m. domesticus,M. m. musculus, andM. m. castaneusfacing potential habitat contractions, whileM. m. bactrianusshows habitat expansion. Variable importance analysis highlights the significance of temperature-related variables, indicating the growing impact of rising temperatures on distribution patterns. Findings underscore the ecological implications of these shifts, emphasizing the need for tailored conservation strategies. The robustness of models, as indicated by high Area Under the Curve (AUC) values, enhances confidence in the reliability of predictions. Despite data limitations, this study contributes valuable insights into the complex dynamics between climate change andMus musculuspopulations, guiding future conservation efforts in the face of ongoing global environmental transformations.
