High levels of gene flow in bur oak revealed by paternity analysis using microsatellites

Microsatellite analysis was used to characterize pollen dispersal in a stand of 62 adult bur oaks (Quercus macrocarpa) in northern Illinois. Using PCR amplification of four dinucleotide microsatellite loci, pollen donors of 282 acorns collected from three adult trees located in different parts of the stand were determined by exclusion. Overall at least 57% of the acorns were pollinated by trees outside of the stand, because all adult trees in the stand were excluded from paternity. Average…

Pollen-mediated gene flow in isolated and continuous stands of bur oak, Quercus macrocarpa (Fagaceae).
- Environmental ScienceAmerican journal of botany

Pollination in three populations of Quercus macrocarpa occurring in a highly altered landscape in northeastern Illinois indicates that extremely isolated stands of oaks are unlikely to be genetically and reproductively isolated, and remnant stands may contribute to maintaining genetic connectivity in highly modified landscapes.
Paternity analysis of pollen-mediated gene flow for Fraxinus excelsior L. in a chronically fragmented landscape
- Environmental ScienceHeredity
- 2008
Paternity analysis based on microsatellite marker genotyping was used to infer contemporary genetic connectivity by pollen of three population remnants of the wind-pollinated, wind-dispersed tree Fraxinus excelsior, in a deforested Scottish landscape suggesting that predictive landscape conservation requires integrated estimates of post-recruitment gene flow occurring via both pollen and seed.

Outcrossing and paternity analysis of Pinus densiflora (Japanese red pine) by microsatellite polymorphism
- Environmental ScienceHeredity
- 2001
This study employed microsatellite loci to analyse outcrossing rate and pollen dispersal in Japanese red pine (Pinus densiflora) in an isolated stand, suggesting that female strobili on a branch of the maternal tree were more easily fertilized by pollen from trees in that direction.
Factors influencing male mating success in bur oak, Quercus macrocarpa
- Environmental ScienceNew Forests

Interestingly, none of these factors were strongly correlated with fertilization success, although weak but significant correlations with crown volume and distance were found, and the results further emphasize the importance of genetically identifying successful pollen donors rather than relying on patterns of physical movement of pollen.
Patterns of pollen and seed dispersal in a small, fragmented population of the wind-pollinated tree Araucaria angustifolia in southern Brazil
- Environmental ScienceHeredity

The results suggest that seed dispersal is restricted but that there is long-distance pollen dispersal between the forest fragment and the tree group; thus, the two stands of trees are not isolated.
High Rates of Gene Flow by Pollen and Seed in Oak Populations across Europe
- Environmental SciencePloS one

The high levels of gene flow in eight stands of white oak suggest that geographically remote oak stands are unlikely to be genetically isolated, questioning the static definition of gene reserves and seed stands.
Pollen movement within a continuous forest of wind-pollinated Araucaria angustifolia, inferred from paternity and TwoGener analysis
- Environmental ScienceConservation Genetics
- 2007
The findings suggest long-distance pollen dispersion (>100 m) inside the continuous forest of A. angustifolia, however, the high proportion occurs in short-distance producing biparental and correlated mating as well as reducing the variance effective size.

Patterns of Pollen Flow and Genetic Differentiation Among Pollen Pools in Quercus salicina in a Warm Temperate Old–growth Evergreen Broad-leaved Forest
- Environmental Science
- 2004
The genetic differentiation of pollen pools between the seed parents showed significant positive correlation with the spatial distance between them, indicating that neighboring seed parents tend to accept similar pollen pools, probably because matings are frequently mediated by pollen transported over short distances.

Fractional paternity procedures were used to examine patterns of pollen movement over two years within two sites of Lathyrus latifolius, a bumblebee‐pollinated, self‐compatible perennial legume, indicating that mating patterns were idiosyncratic to each plant.

The most-likely male parents were identified by using genetic markers and evaluating the statistical likelihoods of paternity for seed collected from known female parents within a natural population of the forest herb Chamaelirium luteum, finding that males had a higher variance in the number of mates, showing a potential for sex-specific selection.
