PHYSIOLOGICAL STATE OF LARVAE: SURVIVING STARVATION AND METABOLIC REGULATION
Century-old questions still remain to be fully answered concerning the biology of marine larvae, such as the biochemical bases of larval growth, what larvae feed on under natural conditions (cf. inferences from laboratory cultures), and the physiological state of larvae in the field. I will discuss these issues by presenting some of our recent studies on (a) the relative roles of endogenous reserves and feeding in metabolism of larvae from different environments; (b) energy requirements of larvae; and (c) the major biochemical processes that establish high metabolic rates in larval forms and the changes in these processes during growth. In terms of understanding the 'mechanisms' of feeding and metabolism, the limitations of the across-species comparative approaches will be discussed and contrasted to the recent use of genetic manipulation to alter growth rates and physiological states of larvae, and the cloning of specific genes that regulate metabolic processes.
