Isotope dilution spaces and elimination rates. (Mean±1 s.d. of ¹⁸O dilution space (N_o, ml), ²H dilution space (N_d, ml), dilution space ratio (N_d/N_o), ¹⁸O elimination rate (k_o, per hour), ²H elimination rate (k_d, per hour) and isotope elimination ratio (k_o/k_d) for Cape ground squirrel females before treatment for parasites (before treatment) and after treatment (after treatment). n denotes sample sizes.)
