We present an updated checklist for all bryophyte species known to occur in the Nordic countries and list occurrences for each taxon from Iceland, the Faroe Islands, Denmark, Svalbard, Jan Mayen, Norway (mainland), Sweden and Finland. Altogether 1276 bryophyte species are included for the region. The checklist includes vernacular names in Icelandic, Danish, Norwegian, Swedish and Finnish. The following new nomenclatural combinations are proposed: Scapania scandica var. parvifolia comb. nov., Andreaea alpina var. hartmanii comb. nov., Didymodon islandicus comb. nov., Ephemerum serratum var. stoloniferum comb. nov., Hygroamblystegium varium var. fluviatile comb. nov., Hygroamblystegium varium var. tenax comb. nov., Ptychostomum arcticum var. purpurascens comb. nov., Ptychostomum intermedium var. nitidulum comb. nov. and Ptychostomum warneum var. mamillatum comb. nov.

Plant dependence on pollinator-aided reproduction may decrease with colder andmore unstable climates, for example at higher elevations. Correspondingly, plant pop-ulations may also be more pollen limited in alpine than in lowlands or under moreoptimal conditions. However, such expectations have largely been investigated acrossspecies, and rarely among populations within a species. The findings of such stud-ies may have implications for predictions of plant sexual reproduction in a changingclimate. We combined a bagging experiment of Vaccinium myrtillus (bilberry) flowerswith a supplemental pollen experiment at three sites along an elevational gradient at100, 500 and 900 m a.s.l. in a mild boreal climate, by the Sognefjord, Norway. Ourgoal was to investigate the variation in reproductive success and pollen limitation ina functionally important plant species, V. myrtillus, and to test whether the outcomesmay be dependent on insect flower visitation and climatic context (i.e. temperaturerelated to elevation). Our experimental treatments clearly affected reproductive suc-cess of V. myrtillus. Bagging of flowers reduced the fruit set close to zero, whereassupplemental pollination resulted in 30% higher fruit set. However, fruit set effectsappeared to be independent of elevation in the current study. Total number of seedswas highest at the optimal mid-site location, but here the proportion of mature seedswas also lowest. Our results clearly showed that the reproductive success of V. myrtillusdepends on pollinator visitation and benefits from extra pollen supply, but that theseeffects appeared to be independent of the climatic context
