Pollen donors of acorns and saplings in a stand of bur oak were identified by paternity exclusion using microsatellite genotype analysis. Here we examine the influence of several factors likely to affect reproductive success of males with wind-dispersed pollen, including distance of pollen donor from maternal tree, genetic relatedness of pollen donor to maternal tree, direction of pollen donor relative to maternal tree, and size of pollen donor (crown volume and trunk diameter).

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.
Long‐distance pollen flow and tolerance to selfing in a neotropical tree species
TLDR
Results, together with the observation that male mating success was correlated with the size of the trees, could be implemented in management procedures aiming at regenerating the species.
Mating patterns and pollen dispersal in four contrasting wild cherry populations (Prunus avium L.)
TLDR
Paternal success was positively correlated with diameter at breast height, as indicated in previous studies and tree dominance only resulted in higher paternal success in low density plots, suggesting that mating patterns were thus also affected by both density and tree size.
Patterns of pollen dispersal in a small population of Pinus sylvestris L. revealed by total-exclusion paternity analysis
TLDR
Results show that the number and distribution of potential pollen donors in small populations may strongly influence the patterns of effective pollen dispersal, mainly caused by the uneven distribution of trees, coupled with restricted dispersal and unequal male success.
Extensive Pollen Flow but Few Pollen Donors and High Reproductive Variance in an Extremely Fragmented Landscape
TLDR
Overall, limited seed dispersal and the scarcity of successful pollen donors can be contributing to generate local pedigrees and to increase inbreeding, the prelude of genetic impoverishment.

Pollen gene flow, male reproductive success, and genetic correlations among offspring in a northern red oak (Quercus rubra L.) seed orchard
TLDR
The feasibility of post hoc assembly of full-sib families for genetic analysis of seed orchard offspring in progeny tests was demonstrated, and distance was the largest influence on pollination success, and pollination occurred most often by male trees in the same subline as the maternal tree.
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.
Genetic diversity of Pinus densiflora pollen flowing over fragmented populations during a mating season
TLDR
The pollen flowing over fragmented P. densiflora populations is considered to have high genetic diversity, compensating to some extent for fragmentation, and the pollen cloud showed slight variation.

High levels of gene flow in bur oak revealed by paternity analysis using microsatellites
TLDR
This study provides direct evidence for high levels of long-distance pollination in a wind-pollinated species, and contradicts traditional models of wind pollination which suggest that clouds of pollen dissipate from the source to ineffectively low densities over short distances.
Microsatellite analysis of seed dispersal and parentage of saplings in bur oak, Quercus macrocarpa
TLDR
This study demonstrates the utility of microsatellite analysis for studying mating systems, seed dispersal and seedling establishment in natural plant populations.

Effective Pollen Dispersal in a Natural Population of Asclepias exaltata: The Influence of Pollinator Behavior, Genetic Similarity, and Mating Success
TLDR
Pollen-mediated gene dispersal within a natural population of poke milkweed, Asclepias exaltata, creates a large neighborhood size in milkweeds that may prevent genetic structure in small local populations, a prerequisite for optimal outcrossing distances to exist.
Gene dispersion within a population of Pinus sylvestris
TLDR
Large variation between trees in their capacity to contribute their genes through natural regeneration is demonstrated, demonstrating no evidence for an increase in levels of inbreeding, or genetic substructuring in the seed...

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.

TLDR
Although gene movements exceeded pollinator flight distances, estimates of neighbourhood size were consistently low, and high levels of random local genetic differentiation are likely in this species.

TLDR
No apparent relationship was found between male size (indicative of reproductive effort) and paternal success, and an alternating pattern of negative and positive spatial autocorrelation in success was found for the first through tenth nearest neighbors, suggesting local competition among males for matings.

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.
