  Rapidity distributions of net hyperons ($\Lambda - \overline{\Lambda}$) are
compared to distributions of participant protons ($p - \overline{p}$).
Strangeness production (mean multiplicities of produced $\Lambda/\Sigma^0$
hyperons and $\langle K + \overline{K} \rangle$) in central nucleus-nucleus
collisions is shown for different collision systems at different energies. An
enhanced production of $\overline{\Lambda}$ compared to $\overline{p}$ is
observed at 200 GeV per nucleon.
