    We offered captive common voles (Microtus arvalis) a choice of 11 plant species (representing four ecological groups) growing in vivaria. Selection was evaluated by measuring (1) the biomass of each plant species consumed and (2) functional and life-history plant traits. We assessed whether plant functional traits explain selective foraging in common voles. To explore this, we reanalyzed Holiova's (1959) data about common vole stomach contents and plant trait databases. We suggest that the voles usually consume grasses in the field because grasses are abundant and readily available, but prefer protein-rich forbs when possible.
