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).
TLDR
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
TLDR
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
TLDR
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
TLDR
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
TLDR
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
TLDR
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
TLDR
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.
Answers Blowing in the Wind: A Quarter Century of Genetic Studies of Pollination in Oaks
TLDR
This review will highlight what has been learned about Quercus pollination, what questions remain, and propose implications for forest management in the face of changing landscapes and climates.
Patterns of Pollen Flow and Genetic Differentiation Among Pollen Pools in Quercus salicina in a Warm Temperate Old–growth Evergreen Broad-leaved Forest
TLDR
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.

This study demonstrates the utility of microsatellite analysis for studying mating systems, seed dispersal and seedling establishment in natural plant populations.
ATTERNS AND LEVELS OF POLLEN‐MEDIATED GENE FLOW IN LATHYRUS LATIFOLIUS

  • 1993
TLDR
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.
EVIDENCE FOR LONG‐DISTANCE POLLEN DISPERSAL IN MILKWEEDS (ASCLEPIAS EXALTATA)
TLDR
Pollen‐mediated gene flow and infrequent interspecific matings provide mechanisms to lower genetic differentiation among populations to maintain novel, low‐frequency alleles within populations of A. exaltata.
Estimates of gene flow in forest trees
TLDR
The results suggested that populations of many species may be concatenated systems bound by gene flow, and the overall levels of gene flow may be influenced by either single or clusters of populations.
Analysis of Paternity within a Natural Population of Chamaelirium luteum. 1. Identification of Most-Likely Male Parents

TLDR
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.
Using Paternity Analysis to Measure Effective Pollen Dispersal in Plant Populations
TLDR
Computer simulations show that the mean distance between inferred males and mother plants (\overline d) reliably estimatesmu_d in defined circumstances, and that the bootstrap method can be used to closely approximate the SE of \ overline d.

TLDR
The measurement of the pollen component of gene flow in the insect-pollinated species, Lupinus texensis is reported, to compare the actual gene flow distribution with the distribution inferred from pollinator flight movements, and to determine the genetic neighbourhood size of this species from the pollen and seed dispersal distributions.

TLDR
Both pollen and seed dispersal components of gene flow were examined in the annual plant Chamaecrista fasciculata (Leguminosae) and quantified in terms of Wright's neighborhood area to determine whether pollinations should be weighted differentially across the flowering season.

Eleven populations of ponderosa pine (Pinus ponderosa) located on an east-west transect of the Palmer Divide of Central Colorado were studied and electrophoretic analyses of mature needle tissue indicated that while most of the allozyme variation resided withintransects, significant genetic heterogeneity could be found between populations and tran Sects.
