New insights from fine-scale spatial genetic structure analyses in plant populations.
Many empirical studies have assessed fine-scale spatial genetic structure (SGS), i.e. the nonrandom spatial distribution of genotypes, within plant populations using genetic markers and spatial autocorrelation techniques. These studies mostly provided qualitative descriptions of SGS, rendering quantitative comparisons among studies difficult. The theory of isolation by distance can predict the ...
متن کاملFine-scale spatial genetic structure within continuous and fragmented populations of Trillium camschatcense.
Spatial genetic structure (SGS) within populations was analyzed for the ling-lived understory perennial herb Trillium camschatcense using allozyme loci. We used Sp statistics to compare SGS between 2 life-history stages, juveniles (J) and reproductives (R), as well as between 2 populations, continuous and fragmented, with different habitat conditions. In the continuous population, significant S...

tion of rare seedling recruitment and clonal growth (Barrett and Silander, 1992; Chapman, 1983; Fothergill White clover (Trifolium repens L.) populations exhibit high genetic et al., 1997; Grime et al., 1988). In addition, somatic and clonal diversity, but often exist for many decades in grazed swards at northern midlatitudes. This study was conducted to determine mutations during vegetative pr...
متن کاملNew interpretations of fine-scale spatial genetic structure.
Recent methodological advances permit refined inferences of evolutionary processes from the fine-scale spatial genetic structure of plant populations. In this issue of Molecular Ecology, Born et al. (2008) exploit the full power of these methods by examining effects of ancient and recent landscape histories in an African rainforest tree species. The authors first detected admixture of distinct ...
متن کاملFine-scale spatial genetic structure and dispersal among spotted salamander (Ambystoma maculatum) breeding populations.
We examined fine-scale genetic variation among breeding aggregations of the spotted salamander (Ambystoma maculatum) to quantify dispersal, interpopulation connectivity and population genetic structure. Spotted salamanders rely on temporary ponds or wetlands for aggregate breeding. Adequate breeding sites are relatively isolated from one another and field studies suggest considerable adult site...
