Contribution of genetics and genomics to seagrass biology and conservation (2007, background): “There is some evidence, in Z. marina, that geographically marginal populations have lower clonal diversity (Reusch et al., 1999c; Billingham et al., 2003), in line with the general hypothesis that plant populations lose sexual fertility at their range margins (=geographic parthenogenesis;…”
Going against the flow: retention, range limits and invasions in advective environments (2006, background): “Such a strategy may help to explain why many species with mixed modes of reproduction (e.g. vegetative or sexual reproduction) primarily reproduce vegetatively or asexually at their distributional limits (Dixon 1965, Whittick 1978, De Wreede & Klinger 1988, Eckert 2002, Billingham et al. 2003).”
Seagrass evolution, ecology and conservation: A genetic perspective (2007, background): “Populations at the distribution limit may also reveal low clonal diversity because sexual reproduction at marginal sites may be reduced or even completely prevented (‘geographic parthenogenesis’ of Bierzychudek (1985) .”
Population genetics of dwarf eelgrass Zostera noltii throughout its biogeographic range (2004, unknown): “…et al. 2002, Billingham et al. 2003) and populations displayed weak to excessively positive (heterozygous deficiency) or negative (heterozygous excess) deviations from Hardy-Weinberg Equilibrium (HWE) (Procaccini & Mazzella 1998, Reusch et al. 2000, Procaccini et al. 2002, Billingham et al. 2003).”
Genetic differentiation and secondary contact zone in the seagrass Cymodocea nodosa across the Mediterranean–Atlantic transition region (2008, background): “Yet we still understand only poorly the distribution patterns of genotypic richness for marine clonal organisms with mixed sexual and asexual reproduction modes (but cf. Billingham et al., 2003; Coyer et al., 2004; Olsen et al., 2004; Tatarenkov et al., 2005; Alberto et al., 2006).”
GENETIC AND MORPHOLOGICAL IDENTIFICATION OF FUCUS RADICANS SP. NOV. (FUCALES, PHAEOPHYCEAE) IN THE BRACKISH BALTIC SEA 1 (2005, background): “…in Fucus toward areas of low salinity is in line with other observations in marginal environments for both plant and animal taxa (Eckert 2001, Billingham et al. 2003, Kearney 2003), including the Baltic Sea (von Wachtenfeldt 1969, Reusch et al. 2000, Gabrielsen et al. 2002, Bergström et al.…”
