How general are positive relationships between plant population size, fitness and genetic variation? (2006, background): “Rare species are typically considered to be genetically less variable than common and widespread species (Karron 1987; Hamrick & Godt 1989; Ellstrand & Elam 1993; Spielman, Brook & Frankham 2004).”
Genetic consequences of habitat fragmentation in plant populations: susceptible signals in plant traits and methodological approaches (2008, background): “Naturally rare species, defined by their narrow geographical range, restricted habitat specificity or small local population sizes (sensu Rabinowitz 1981) are usually genetically less diverse than more widespread or common species (Karron 1987; Hamrick & Godt 1989; Ellstrand & Elam 1993).”
The biogeography of plant reproduction: potential determinants of species’ range sizes (2006, background): “…readily admit that generalized conditions of rarity or abundance are unlikely to be attributable to any one factor (Watson, 1833; Cruden, 1977; Karron, 1987; Murray et al., 2002; Maki, 2003; Lavergne et al., 2004, 2005; Shapcott et al., 2005) As a result of these methodological difficulties,…”
The biology and ecology of narrow endemic and widespread plants: a comparative study of trait variation in 20 congeneric pairs (2004, background): “…analysis of the ecology and biology of large Accepted 25 May 2004 Copyright # OIKOS 2004 ISSN 0030-1299 OIKOS 107: 505 /518, 2004 OIKOS 107:3 (2004) 505 samples of paired species which differ in range size and occur in different phylogenetic contexts (Karron 1987, Edwards and Westoby 1996).”
Ploidy influences rarity and invasiveness in plants (2011, background): “For rarity, the best known genetic correlate is a decreased level of genetic diversity (e.g. Karron 1987; Sherman-Broyles et al. 1992), presumably linked to the inbreeding and genetic drift inherent in small, isolated populations.”
