Predicting the potential global distribution of Ixodes pacificus under climate change

range for Prec1 is between 70-626mm, with the most suitable precipitation being 300mm. When the precipitation is between 70-300mm, the probability of existence gradually increases. When the precipitation is between 327-626mm, the distribution probability has small fluctua- tions but is generally stable (Fig 7A). The suitable temperature for the Tmin2 (with a probabil- ity of � 0.6) is between -45.1–7.9˚C. When the temperature is between -45.1–15.9˚C, the distribution probability increases with the increase of temperature. When the temperature is between -15.9–1.7˚C, the distribution probability fluctuates with an increase and a decrease, and there are three peaks in distribution probability. When the temperature is about -11.2˚C, Fig 2. Pearson correlation analysis of environmental variables. The blue dots in the figure represent positive correlation, the red dots represent negative correlation, and the darker the color, the stronger the correlation. https://doi.org/10.1371/journal.pone.0309367.g002 Table 2.
