Field and Laboratory Studies of Giffordia mitchelliae (Phaeophyceae) in North Carolina

Academic Article


  • In culture Giffordia mitchelliae (Harvey) Hamel grows best between 15 and 20 °C, corresponding to spring and autumn seawater temperatures in nature. The life history of G. mitchelliae in culture appears to be direct, which contridicts an earlier report from North Carolina (U.S.A.). The response of G. mitchelliae to temperature in culture aids in clarifying its seasonality in the state. Giffordia mitchelliae has been reported as most common during spring and autumn in nature. Morphometric analyses of G. mitchelliae coupled with a review of previous descriptions of G. indica (Sonder) Papenfuss et Chihara from North Carolina indicate that these reports may represent misidentified G. mitchelliae. It is suggested that all warm temperate records of G. indica be reexamined. © 1985, Walter de Gruyter. All rights reserved.
