  Einstein-Podolsky-Rosen (EPR) steering allows Alice to remotely prepare a
state in some specific bases for Bob through her choice of measurements. The
temporal analogue of EPR steering, temporal steering, also reveals the
steerability of a single system between different times. Focusing on a
four-dimensional system, here we investigate the dynamics of the temporal
steering measures, the temporal steering robustness, using 5 mutually unbiased
bases. As an example of an application, we use these measures to examine the
temporal correlations in a radical pair model of magnetoreception. We find
that, due to interactions with a static nuclear spin, the radical pair model
exhibits strong non-Markovianity.
