  • The institutional data repository DataSuds provides IRD scientists and their partners with a service to disseminate, preserve and enhance their multi-disciplinary research data by facilitating their identification and citation. It is one of the elements of the open science system for the South promoted by IRD.

  • Paramecia are unicellular eukaryotes of large size (~ 120 micrometers for P aurelia species) that belong to the ciliate phylum. Ciliates, like the Last Eukaryotic Common Ancestor, have the axonemal structure in the form of vibrating cilia that assure locomotion and food capture and are essential for pairing of paramecia of opposite mating types during conjugation (sexual reproduction). Like multicellular eukaryotes, ciliates separate germinal and somatic functions, harbouring two different kinds of nuclei. A diploid germinal micronucleus transmits the genetic information to the next sexual generation, while a polyploid somatic macronucleus is responsible for gene expression. Reproducible DNA elimination, which occurs in many animal lineages, takes place in ciliates during sexual reproduction, when a new somatic macronucleus develops from a copy of the germline micronucleus. The somatic genomes of numerous Paramecium species are being sequenced and annotated. ParameciumDB integrates the genomes as they become available, to provide resources for functional and comparative genomics to the community. ParameciumDB interfaces and tools have been redesigned. Your feedback is welcome.

  • Fulgoromorpha Lists On the Web (FLOW) is an online database that aims to provide an easy-access summary of available biological published primary data on planthoppers (Hemiptera, Fulgoromorpha), a group of major economic importance. It includes information on taxonomy, nomenclature, bibliography, distribution and various associated biological information on host-plants and parasites (including fossils).
