The influence of both quantal and thermal fluctuations on the level-density parameter {ital a} in hot nuclei is investigated. It is found that the large-amplitude motion of the nuclear surface has little influence on {ital a} and that the observed temperature and angular momentum behavior is properly explained through the thermal properties of the energy-dependent effective mass.
