We discuss the influence of lowest-Landau-level (LLL) fluctuations near (Formula presented) on flux-lattice melting in (Formula presented) (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.
