Y. auteur aut IRD text journalArticle eng text/pdf born digital access Although the monophyly of Chiroptera is well supported by many independent studies, higher-level systematics, e.g. the monophyly of microbats, remains disputed by morphological and molecular studies. Chromosomal rearrangements, as one type of rare genomic changes, have become increasingly popular in phylogenetic studies as alternatives to molecular and other morphological characters. Here, the representatives of families Megadermatidae and Emballonuridae are studied by comparative chromosome painting for the first time. The results have been integrated into published comparative maps, providing an opportunity to assess genome-wide chromosomal homologies between the representatives of eight bat families. Our results further substantiate the wide occurrence of Robertsonian translocations in bats, with the possible involvement of whole-arm reciprocal translocations (WARTs). In order to search for valid cytogenetic signature(s) for each family and superfamily, evolutionary chromosomal rearrangements identified by chromosomal painting and/or banding comparison are subjected to two independent analyses: (1) a cladistic analysis using parsimony and (2) the mapping of these chromosomal changes onto the molecularly defined phylogenetic tree available from the literature. Both analyses clearly indicate the prevalence of homoplasic events that reduce the reliability of chromosomal characters for resolving interfamily relationships in bats. specialized 080 020 16 1 155-170 2008 0967-3849 https://www.documentation.ird.fr/hor/fdi:010040979 10.1007/s10577-007-1206-2 0967-3849 [F B010040979] https://www.documentation.ird.fr/hor/fdi:010040979 https://www.documentation.ird.fr/intranet/publi/2008/03/010040979.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2008-03-31 2017-08-23 fdi:010040979 fre
