| Popis: | The origin of introduced Nile tilapia stocks in sub-Saharan Africa is largely unknown. In this study, the potential of monogeneans as a biological tag and magnifying glass is tested to reveal their hosts' stocking history. The monogenean gill community of different Nile tilapia populations in sub-Saharan Africa was explored, and a phylogeographic analysis was performed based on the mitogenomes of four dactylogyrid species (Cichlidogyrus hani, C. sclerosus, C. thurstonae, and Scutogyrus longicornis). Our results encourage the use of dactylogyrids as biological tags. The magnifying glass hypothesis is only confirmed for C. thurstonae, highlighting the importance of the absence of other potential hosts as prerequisites for a parasite to act as a magnifying glass. With the data generated here, we are the first to extract mitogenomes from individual monogeneans and to perform an upscaled survey of the comparative phylogeography of several monogenean species with unprecedented diagnostic resolution.

Molecular work was funded through research grant 1513419 N of the Research Foundation—Flanders (FWO-Vlaanderen), and part of leading to results presented in this publication was carried out with infrastructure funded by the European Marine Biological Research Centre (EMBRC) Belgium, FWO-Vlaanderen project GOH3817N. The field expedition to the DRC was partly financed by the Stichting ter Bevordering van het Biodiversiteitsonderzoek in Afrika (SBBOA) fund.the research We appreciate the help of the people involved in the field work and sampling procedure. Furthermore, we would like to thank Christopher Laumer (EMBL-European Bioinformatics Institute, UK) and Gontran Sonet (Royal Belgium Institute of Natural Sciences, Belgium) for providing us with the extraction protocol and R scripts, respectively. We could also like to acknowledge Wim Bert, Christoph Hahn, Nikol Kmentova, ´ Jos Snoeks, and Carl Vangestel for suggestions on an earlier version of this manuscript. Finally, we would like to thank Ria Vanderspikken (Hasselt University, Belgium) and Natascha Steffanie (Hasselt University, Belgium) for their technical support in the laboratory |
