摘要

Genetic variability, shell morphology, anatomy, reproductive season, glochidium morphology and host fish of several Iberian populations of Unio mancus Lamarck, 1819 (= U. elongalulus C. Pfeiffer, 1825) were examined. The genetics of three allopatric populations were studied, including two 'races' previously described for this species on the Iberian Peninsula. All shared the same haplotypc of the COI mitochondrial gene. It is proposed that all known'Iberian Mediterranean populations of the genus Uniocorrespond to Unio mancus. All mature specimens studied were dioecious. Glochidial release occurred between March and August. The barbel Barbus graellsii was the natural host of the U. mancus glochidia in the studied area. In artificial infestations performed in aquaria, seven fish species, all native, carried the glochidia throughout their complete metamorphosis. This process occurred in 141 degree/days. Newly released juveniles were spherical and had a thin marginal rim of new shell.

Pfeiffer，1825）。研究了三个异源种群的遗传学，包括先前在伊比利亚半岛对该物种的两个“种族”。所有人都共享相同的COI线粒体基因单倍型。建议Uniocor属的所有已知的'伊比利亚地中海种群都对Unio mancus做出反应。所有研究的成熟标本都是雌雄异体的。 glochidial释放发生在3月至8月之间。杠铃Barbus graellsii是所研究地区的曼氏弓形虫的自然寄主。在水族箱中进行的人工侵染中，全部原生的七种鱼类在整个变态过程中携带了甲壳纲。此过程发生在141度/天。新发布的幼虫是球形的，边缘较薄，有新壳。
