| effects of kin-structured seed dispersal on the genetic structure of the clonal dioecious shrub ilex leucoclada. | nonrandom patterns of gene dispersal have been identified as possible causes of genetic structuring within populations. attempts to model these patterns have generally focused solely on the effects of isolation by distance, but the processes involved are more complex than such modeling suggests. here, we extend considerations of gene dispersal processes beyond simple isolation by distance effects by directly evaluating the effects of kin-structured gene dispersal mediated by the group dispersal ... | 2007 | 17542840 |
| fine-scale clonal structure and diversity within patches of a clone-forming dioecious shrub, ilex leucoclada (aquifoliaceae). | the mode of reproduction (sexual vs. asexual) is likely to have important effects on genetic variation and its spatial distribution within plant populations. an investigation was undertaken of fine-scale clonal structure and diversity within patches of ilex leucoclada (a clone-forming dioecious shrub). | 2005 | 15546930 |
| clonal diversity and genetic differentiation in ilex leucoclada m. patches in an old-growth beech forest. | we investigated clonal diversity within patches of ilex leucoclada and genetic variation within and among patches using random amplified polymorphic dna (rapd) markers in a 1-ha plot within an old-growth beech forest. we found 38 patches that exhibited a clumped distribution in the middle of the plot. we identified a total of 166 rapd phenotypes among the 215 stems sampled from 27 patches that were completely within the plot. the population showed high clonal diversity within patches (mean numbe ... | 2003 | 12753203 |
