Abstract

Most species are assumed to have survived south or east of the ice sheet covering northern Europe during the last glacial maximum. Molecular and macrofossil evidence suggests, however, that some species may have survived in ice-free areas in Scandinavia. In plants, inbreeding and vegetative growth are associated with low genetic load and enhanced survival in small, isolated populations. These characteristics are often found in bryophytes, possibly allowing them to survive extreme conditions in isolated refugia and also within ice sheets. Here, we review the Holocene bryophyte history in Europe highlighting main glacial refugia and post-glacial colonization routes. Also, meta-analyses are performed to investigate if distribution ranges and genetic structure are associated with life-history traits. Bryophytes survived the last glaciation in several refugia, but there is no unequivocal evidence of survival within the Scandinavian ice sheet. Northern Europe was colonized from southern, eastern and western Europe, as well as North America. Species with small spores have broader distribution ranges than species with large spores, and high frequency of sporophyte production is associated with limited genetic differentiation between populations.
欧洲苔藓植物的冰川避难所和冰川后殖民模式
大多数物种被认为是在最后一次极大期覆盖北欧的冰盖的南部或东部幸存下来的。然而,分子和宏观化石证据表明,一些物种可能在斯堪的纳维亚半岛的无冰地区幸存下来。在植物中,近亲繁殖和营养生长与低遗传负荷和在小的、孤立的种群中提高存活率有关。这些特征通常存在于苔藓植物中,可能使它们能够在孤立的避难所和冰盖的极端条件下生存。在此,我们回顾了欧洲全新世苔藓植物的历史,重点介绍了主要的冰川避难所和冰川后的殖民路线。此外,还进行了荟萃分析,以调查分布范围和遗传结构是否与生活史性状相关。在几个避难所中,苔藓植物在最后一次冰期中幸存下来,但没有明确的证据表明它们在斯堪的纳维亚冰盖中幸存下来。北欧是南欧、东欧和西欧以及北美的殖民地。具有小孢子的物种比具有大孢子的物种分布范围更广,孢子体产生的高频率与种群间有限的遗传分化有关。
