We show that reactions such as $Λ(1520)+π\leftrightarrow Σ^*$ can favor $Σ^*$ production, thereby decreasing the $Λ(1520)$ yield. Within the same approach we thus find a yield enhancement for $Σ(1385)$ and a yield suppression for $Λ(1520)$.13 pages, 9 figures, accepted to Physical Review C, right figure 9 was replaced because lines style was mixed upNuclear Theorytext
