We discuss the influence of lowest-Landau-level (LLL) fluctuations near Hc2(T) on flux-lattice melting in YBa2Cu3O_7\ensuremath-\ensuremathδ (YBCO). We show that the specific heat step of the flux-lattice melting transition in YBCO single crystals can be attributed largely to the degrees of freedom associated with LLL fluctuations. These degrees of freedom have already been shown to account for most of the latent heat. We also show that these results are a consequence of the correspondence between flux-lattice melting and the onset of LLL fluctuations.
