a Map of Tahiti showing the valley sampling locations for the endemic Tahitian tree snail Partula hyalina (green circles) and the invasive alien predator Euglandina rosea (red circles) study populations. b An aestivating specimen of P. hyalina attached to the underside of an Alocasia macrorrhiza leaf, Faarapa Valley study site. Our permit did not allow us to attach a sensor directly to the endemic species so the tree snail is flanked by two light sensors measuring its immediate (under leaf) environment and by a magnet anchoring an upper leaf light sensor measuring the leaf’s ambient (leaf top) environment. c A foraging E. rosea specimen bearing an attached solar sensor, Fautaua Valley study site.
