Relativistic Hartree-Fock calculations indicate that the dipole oscillator strengths for the $2s\ensuremath{\rightarrow}2{p}_{\frac{3}{2}}$ and $2s\ensuremath{\rightarrow}3{p}_{\frac{3}{2}}$ transitions of the Li sequence and those for the $2{s}^{2}^{1}S\ensuremath{\rightarrow}2s2{p}_{\frac{3}{2}}{P}_{1}$ transitions of the Be sequence deviate appreciably for $Z>40$ from values extrapolated from low-$Z$ ions.
