Summary: Pollinator sharing between early orchid species does not lead to character displacement, indicating a low cost of pollinator sharing. Our results highlight the importance of characterizing both traits and ecological niches in character displacement studies.

Summary: Human-mediated environmental change can strengthen selection on traits of interacting species. This study found that reduced pollinator populations increased pollen limitation in Lobelia siphilitica plants, leading to stronger pollinator-mediated selection for traits such as taller inflorescences and more vibrant petals that can attract pollinators.

Summary: This study examines the role of pollinators in the evolutionary divergence of floral traits in food-deceptive orchids. By building a fitness function, the researchers were able to estimate the strength of pollinator-mediated selection through female reproductive success. The results show that selection is more significant and variable when pollination is less reliable.

Summary: This study demonstrates that specific traits and trait combinations between donor and recipient species are crucial in determining seed production outcomes. Differences in traits between species lead to a competitive structure with clear winners or losers species.

Summary: This study aims to determine if monoecious plants can effectively avoid self-interference and promote the evolution of monoecy under the service of pollinators. The results show that pollinator-mediated self-interference significantly reduces selfing, providing potential dynamics for the maintenance and evolution of monoecy.

Summary: Species diversity can vary greatly across lineages due to differences in speciation and extinction rates. This study examines the effects of various plant traits on diversification and finds that most traits have contrasting effects. The complexity of pathways linking traits to diversification suggests that interpreting their correlations may be challenging, and the context dependence means that the effects of specific traits on diversification may differ across lineages and timescales. This calls for taxonomically and context-controlled approaches in studying trait-diversification relationships.

Summary: Species diversity can vary greatly due to differences in speciation and extinction rates. This study examines the effects of various plant traits on diversification and finds that most traits have conflicting impacts. The complexities of trait-diversification relationships and context dependence highlight the need for controlled approaches in correlational studies.

Summary: This study found that invasive goldenrods did not suffer from pollinator shortage and ineffective pollination, especially in habitats densely covered by the invader, due to the presence of large-bodied pollinators, which affected the composition of pollinators and pollination effectiveness.

Summary: This study reveals that male-male interference during pollen dispersal can significantly limit plant-siring success by affecting pollen pickup, transport, and deposition. Competitive pollinaria on bees reduce pickup of additional pollinaria, double the overall proportion of lost donor pollen, and decrease total pollen export. Interference specifically increases loss of donor pollen between flower visits and variation in deposition among trials, potentially reducing pollen contact with stigmas and pollen deposition.

Summary: This study investigated the relationship between yield and pollinator density in sunflowers and found the importance of random effects and plant maternal resources in evaluating pollen limitation. It also demonstrated that pollinator gradients on a per flower basis are a useful tool to identify target pollinator densities for maximizing yields. Furthermore, insect pollination had a positive impact on the seed number, mass, and oil content of sunflowers.

Summary: The study found that Caragana microphylla plants exhibited pollen limitation, with heavy grazing significantly reducing seed production in plants that underwent open-pollination. However, there was no significant difference in seed production between plants in the control group and those in the moderate grazing group. Plants in the control group had a higher pollinator visitation frequency compared to those in the heavy grazing group.

Summary: The evolution of floral traits in animal-pollinated plants involves the interaction between flowers and pollinators. Research shows that pollinator-mediated selection has limited impact on continuous color variation in flowers. The complex interactions between flower colors and pollinator sensory abilities, cognitive responses, and behavior warrant further investigation in understanding the distribution of color phenotypes and fitness.

Summary: This study investigated the variability in reproductive success and pollen limitation in red-listed Polemonium caeruleum. The results showed that pollen limitation rarely affected P. caeruleum populations, and mainly occurred in small populations. Honeybee visits and population size had a negative impact on the pollen limitation index, while population size, hoverfly visits, and average monthly precipitation in June had a positive influence on seed production.

Summary: This study investigates the impact of human disturbance on the reproductive output of Anacamptis robusta plant species, as well as the effects of competition, fungal infections, and hybridization processes on its fitness. Findings suggest that the disturbed subpopulation of A. robusta has lower fruit set success compared to well-conserved areas and that the presence of A. coriophora negatively affects its reproductive output.

Summary: Pollen plays a crucial role in plant reproductive biology. Recent advancements in pollen-tracking methods and statistical approaches have provided exciting new insights into the relationships between pollen production, presentation, flower morphology, and pollination performance. This special issue highlights the studies that contribute to our understanding of the role of pollen in linking plant phenotypes to reproductive fitness, and presents opportunities for further development in this field.
