John F. Piatt W.A. Montevecchi 1987 <p><span>We present evidence to indicate that dehydration of prey transported by seabirds from capture sites at sea to chicks at colonies inflates estimates of wet weight energy densities. These findings and a comparison of wet and dry weight energy densities reported in the literature emphasize the importance of (</span><i>i</i><span>) accurate measurement of the fresh weight and water content of prey, (</span><i>ii</i><span>) use of dry weight energy densities in comparisons among species, seasons, and regions, and (</span><i>iii</i><span>) cautious interpretation and extrapolation of existing data sets.</span></p> application/pdf 10.1139/z87-427 en NRC Research Press Dehydration of seabird prey during transport to the colony: Effects on wet weight energy densities article
