| The faunal diversity of Lake Tanganyika, with its fish species flocks and its importance as a cradle and reservoir of ancient fish lineages seeding other radiations, has generated a considerable scientific interest in the fields of evolution and biodiversity. The Tropheini, an endemic Tanganyikan cichlid tribe, fills a peculiar phylogenetic position, being closely related to the haplochromine radiations of Lakes Malawi and Victoria. Several problems remain regarding their genus-level classification. For example, the monotypic genus Interochromis is phylogenetically nested within Petrochromis; its only representative, I. loocki, has often been reclassified. As monogenean flatworms are useful markers for fish phylogeny and taxonomy, the monogenean fauna of... |

| The carotenoid composition of <i>Artemia</i> cysts from 17 geographical strains was studied. All-<i>trans</i>-canthaxanthins and <i>cis</i>-canthaxanthins were quantitatively determined using a non-aqueous reversed phase chromatographic method. In dehydrated cysts, the average <i>cis</i>- and <i>trans</i>-canthaxanthin levels (+/- SD) were 152 +/- 52 and 134 +/- 42 µg/g, respectively (range 38-227 and 67-201µg/g). The corresponding concentrations in hydrated cysts were (<i>cis</i>) 177 +/- 60 µg/g (range 47-271 µg/g) and (<i>trans</i>) 112 +/- 35 µg/g (range 52-169 µg/g). The <i>cis/trans</i> concentration ratios averaged 1.13 (range 0.57-1.47) and 1.60 (range... |
