Range Shifts Under Constant-Speed and Accelerated Climate Warming

Many species are experiencing range shifts as the climate warms. Earlier models have considered moving-habitat scenarios where the shift speed of the moving habitat is either constant or fluctuates around a constant speed. This paper considers scenarios where the shifting speed may either be constant or accelerated. In addition to population persistence, the paper also analyzes the range-shift deficit, which is a lag in the spatial distribution of the population. Another highlight of the results is an analytic formula for a population persistence metric in a particular example, which adds to existing analytic formulas about this persistence metric in the literature.

Automated summary

This paper investigates the impact of climate warming on species' range shifts, considering scenarios where the shifting speed may be either constant or accelerated. In addition to population persistence, the study also analyzes the lag in the spatial distribution of the population, and provides an analytic formula for a population persistence metric in a specific example, adding to existing literature on this topic.
