Huffeldt, N. P. (2020). Photic Barriers to Poleward Range-shifts. Trends Ecol Evol, in press.
Abstract: With climate warming, organisms are shifting their ranges towards the poles, tracking their optimal thermal environments. Day-length, the driver of daily and annual timing, is, however, fixed by latitude and date. Timing and photoreception mechanisms adapted to ancestral photic environments may restrict range-shift capacity, resulting in photic barriers to range-shifts.
