资源简介：
Third file: “Pollen transfer effectiveness data.csv”. These data were all collected in 2003. The column headings represent: “Sample”=the specimen identifier; “Species”= visitor species (Apis= Apis mellifera, Bombus= Bombus spp., Vespula= Vespula pennsylvanica); “Pollen”=were pollen grains found (y) or not (n) on the stigma; “Estgrains”=estimated number of pollen grains deposited (some numbers are fractions because values for stigmas that were more difficult to score represent means of two different counts).
