| This is a review on some biological and ecological characteristics of the early life stages of myctophids that exemplify their adaptations to coastal upwelling zones and oceanic nearby areas. The approach has been, however, not to make an exhaustive list of all possible research subjects but, in a more pragmatic way, a) to identify relevant aspects that can be approached with currently available methods in the region and, b) through examples of studies published nationally and regionally, to stimulate future research in larval ecology in the Humboldt Current. Three major themes were assessed: taxonomy and systematics, population ecology and reproductive strategies and, ecophysiology of the early life stages. Among the former, we detected a lack of... |

| The diving behavior and diet composition of King penguins were examined during summer 1995 at Kerguelen Islands. This was in relation to real-time estimations of diel prey availability during 2 sampling sessions totaling 10 d at sea. During daylight hours King penguins performed medium to deep dives of 120-250 m. At night, they dived no deeper than 60 m. Daytime, dusk and night-time sampling of prey was performed in the depth ranges corresponding to the depths of the penguins' dives in this study. The diversity in mesopelagic fish was found to be highest during the night at 0-50 m (15 vs 9 species during the day), and their number was up to 20-fold higher at these depths at night than during the day at the 150-250 m depth layer. The 3 myctophid species... |
