This Thesis contributes to elucidate the life cycle strategies of two copepod species, the medium-size clausocalanid Drepanopus forcipatus Giesbrecht, 1888 and the large calanid Calanus australis Brodsky, 1959, in relation to the environmental conditions in the southern Patagonian shelf (47°-55°S). This research was mainly carried out with samples collected in late summer/early autumn (March/April, 2004) onboard RV "Dr. E. L. Holmberg" (INIDEP, Mar del Plata). An additional sampling performed during early spring (October, 2005) with RV "Puerto Deseado" (CONICET) was also utilized. The present study was based on the following research questions: 1) Which is the available food for copepod populations by late summer? 2) Which is the relative contribution of D. forcipatus and C. australis to the summer mesozooplankton community conformation in the southern Patagonian shelf when it is determined from samples collected by a fine mesh size net? 3) Which feeding and reproductive activity level.....
