WebNov 28, 2024 · Our results show that while large-bodied pollinators set more seeds per visit, small-bodied bees visited flowers more frequently and were responsible for more than 49% of all long-distance (beyond 1 km) pollen-dispersal events. Thus, despite their size, small-bodied bees play a critical role in facilitating long-distance pollen-mediated gene flow. WebApr 13, 2024 · Introduction. In flowering plants, gene flow occurs predominantly through the dispersal of pollen, and subsequent seed set from pollinated ovules [1, 2].Gene flow can also occur through the dispersal of seeds [3, 4].Insects move pollen between flowers, and most flowering plants, including a large number of fruit crops, most vegetable crops when …

Webgene flow. While gene flow has been estimated based on allozyme and microsatellite data for many social bees (reviewed in Packer and Owen, 2001), no studies have focused on solitary or communal ground nesting desert bees, which comprise the majority of bees in the areas of highest bee diversity (arid regions). We present below the results of a long WebDespite the ecological and economic importance of wild bees and the fact that several species are now managed for pollination services worldwide, little is known about how land use and beekeeping practices jointly influence gene flow.
