Variability in biotic interaction strength is an integral part of food web functioning. However, the consequences of the spatial and temporal variability of biotic interactions are poorly known, in particular for predicting species abundance and distribution. The amplitude of rodent population cycles (i.e. peak phase abundances) has been hypothesized to be determined by vegetation properties in tundra ecosystems. We assessed the spatial and temporal predictability of food and shelter plants effects on peak phase small rodent abundance during two consecutive rodent population peaks. Rodent abundance was related to both food and shelter biomass during the first peak, and spatial transferability was mostly good. Yet, the temporal transferability of our models to the next population peak was poorer. Plant-rodent interactions are thus temporally variable and likely more complex than simple one-directional (bottom up) relationships or variably overruled by other biotic interactions and abiotic factors. We propose ... : plant and rodent data during first peak for Microtus oeconomusMicrotus oeconomus numbers and related plant functional group biomass during small rodent population peak 2006-2007.plant_rodent_1st_peak_mic_oec.txtplant and rodent data during first peak for Myodes rufocanusMyodes rufocanus numbers and related plant functional group biomass during small rodent population peak 2006-2007.plant_rodent_1st_peak_myo_ruf.txtplant and rodent data during first peak for Lemmus lemmusLemmus lemmus numbers and related plant functional group biomass during small rodent population peak 2006-2007.plant_rodent_1st_peak_lem_lem.txtplant and rodent data during second peak for Microtus oeconomusMicrotus oeconomus numbers and related plant functional group biomass during small rodent population peak 2010-2011.plant_rodent_2nd_peak_mic_oec.txtplant and rodent data during second peak for Myodes rufocanusMyodes rufocanus numbers and related plant functional group biomass during small rodent population peak ...
