Resumen en inglés

Samples collected from ponds in central Mexico contained male and female specimens of the harpacticoid copepod Elaphoidella grandidieri (Guerne & Richard, 1893). Field-collected ovigerous females were transported to the laboratory where several isofemale lines were established. Cultures were established from a single female and maintained on a mono-algal diet in moderately hard water. Specimens of both sexes, particularly the less known males, were analysed morphologically and compared with records from different geographical regions. Differences among these populations are subtle and not geographically consistent. Variations were found in the relative length of setal elements and ornamentations of swimming legs 1, 2, and 4, the proportions and armature of the exopod of the female leg (P) 5, among other characters. The specimens from Mexico have 1-2 long spines near the posteroventral margin of the anal somite; this character has been described only from a North African population. Our analysis supports the notion that this widespread pantropical species shows a considerable degree of variability in various characters. Since a clonal population of this parthenogenetic species could be established, molecular techniques are recommended to evaluate this variability and determine if E. grandidieri represents a species complex with morphologically similar taxa. The finding of E. grandidieri as an harpacticoid with high reproductive rates suggests that this copepod has an outstanding potential in aquaculture.

Resumen en portugués

Des échantillons collectés dans des mares du centre du Mexique contenaient des spécimens mâles et femelles du copépode harpacticoïde Elaphoidella grandidieri (Guerne & Richard,1893). Des femelles ovigères collectées sur le terrain ont été transportées au laboratoire où plusieurs lignées isofemelles ont été établies. Les élevages ont été réalisés à partir d’une femelle unique et maintenus dans de l’eau moyennement dure avec un régime alimentaire mono-algue. Des spécimens des deux sexes, en particulier les mâles, moins connus, ont été analysés quant à leur morphologie et comparés avec les données de différentes régions géographiques. Les différences entre ces populations sont subtiles et ne sont pas cohérentes géographiquement. Des variations ont été trouvées dans la longueur relative des soies et des ornementations des pattes natatoires P1, P2 et P4, dans les proportions et l’armature de l’exopodite de la P5 femelle, parmi d’autres caractères. Les spécimens du Mexique ont 1-2 longues épines près du bord postéroventral du somite anal ; ce caractère a été décrit seulement d’une population nord-africaine. Notre analyse soutient la notion que cette espèce pantropicale largement répartie présente un degré considérable de variabilité pour différents caractères. Étant donné qu’une population clonale de cette espèce parthénogénétique pourrait être obtenue, des techniques moléculaires sont recommandées pour évaluer cette variabilité et déterminer si E. grandidieri représente un complexe d’espèces avec des taxons morphologiquement similaires. Le fait que E. grandidieri présente un taux de reproduction élevé suggère un potentiel remarquable pour l’aquaculture chez cette espèce.

Resumen en inglés

The influence of Bernard Dussart's contributions to limnology in general as well as to freshwater copepodology in particular can hardly be overestimated. From 1945 until his decease late 2008, he has devoted more than 60 years of his life to studying freshwater bodies and their inhabitants. Next to his 200+ scientific papers, his frequent travels brought him all over the world, where he invariably left an inheritage of enhanced interest in problems of freshwater biology and management. The contributions in this book show the progress of research on the Copepoda found in continental waters and in part continue along the lines B. Dussart has set out: a worthy tribute to one of the very nestors of copepodology of fresh waters.
