Recent and recurrent polyploidy in Tragopogon (Asteraceae): cytogenetic, genomic and genetic comparisons (2004, background): “…of genotypes are best seen in the arctic where diploid parents co-occur repeatedly on a circumboreal scale, thus explaining the well-known taxonomic uncertainty surrounding arctic polyploid complexes (D. Soltis & P. Soltis, 1999; Abbott & Brochmann, 2003; Brochmann et al., 2004 – this issue).”
The Incidence of Polyploidy in Natural Plant Populations: Major Patterns and Evolutionary Processes (2013, background): “In recent years, high-throughput analyses of polyploidy have been extended into the arctic (Brochmann et al. 2004) and less-studied regions at lower latitudes (Popp et al.”
Molecular mechanisms of polyploidy and hybrid vigor (2010, background): “The proportion of polyploid flowering plants might be over 70% [14], and the majority of them (>75%) are allopolyploids [15,16].”
The advantages and disadvantages of being polyploid (2005, background): “Phylogenetic analyses indicate that arctic allopolyploids form frequently and have been particularly efficient at invading newly deglaciated areas, probably because their genomes confer hybrid vigour and buffer against the effects of inbreedin”
The scaling of genome size and cell size limits maximum rates of photosynthesis with implications for ecological strategies (2019, background): “Polyploids have been hypothesized to be better adapted to extreme habitats, to have greater hardiness, and to have greater ecological adaptability (reviewed by Stebbins 1985: Brochmann et al. 2004).”
The role of hybridization in plant speciation. (2009, background): “, for some genes the homeolog of parental species A is silenced and at other genes the homeolog of parental species B is silenced Many cryptic allopolyploid (as well as autopolyploid) species may also be present in the arctic flora, where polyploid species are well known for their taxonomic complexi”
The biogeography of plant reproduction: potential determinants of species’ range sizes (2006, background): “Consequently, single dispersed propagules of polyploid species can establish new colonies more effectively (Stebbins, 1950; Lumaret et al., 1997; Brochmann et al., 2004).”
‘why polyploidy is rarer in animals than in plants’: myths and mechanisms (2004, background): “We are still in the early stages of understanding the factors contributing to the origin and establishment of polyploidy lineages, but the diversity of papers in this symposium related to these questions (Abbott & Lowe, 2004; Ainouche et al., 2004; Brochmann et al., 2004; Gallardo et al., 2004; Husb”
The more the better? The role of polyploidy in facilitating plant invasions. (2012, background): “Nevertheless, the fact that polyploid perennials are the predominant life form in the Arctic (Brochmann et al., 2004) suggests the opposite.”
Angiosperm polyploids and their road to evolutionary success (2010, background): “For instance, polyploids have been reported to be abundant at high latitudes and high altitudes,(11,12) a wellknown example being the high frequency of polyploids in arctic areas.(15,16) So what are the different factors that might explain the appar-”
