“…In α diversity (but not visitation frequency), bees were much more present in P. hirsuta. This result confirms earlier studies which identified Limonene and -Pinene, as well as pink petal color as floral attractants for α hymenopterans (Aceves-Chong et al, 2018;Byers et al, 2014). However, Linalool and yellow petals have been found to be attractive to bees, moths (Riffell et al, 2009) and a range of other pollinators (Raguso, 2016), so these factors alone cannot explain the observed difference in pollinator communities.…”

Adaptation to siliceous versus carbonate substrates is thought to be an important driver of speciation in the alpine flora. The role of the pollination system in formation and maintenance of such species is presently unclear. Here, we chose three species pairs in the genera Gentiana, Primula, and Rhododendron which often occur in geographic proximity or even sympatry, to study the existence of pollination barriers in these lineages. Using remote camera and direct observation approaches, scent and color analyses, and morphological comparisons, we tested the hypothesis that divergent pollinator communities help to maintain genetic separation of plant populations adapted to different soil types. We found differences in frequency, diurnal activity and to some extent also community composition of flower visitors in edaphic vicarious species pairs. Floral traits like color and scent as well as plant-flower-visitor co-distributions indicate that there are divergent but overlapping pollination systems. Our results suggest a relatively small reproductive barrier function of the pollination system. While the adaptation to different soils still seems to be the main force keeping edaphic vicarious alpine plants genetically separated, pollinators might break down hybridization barriers in contact areas.

“…In other reports, linalool was observed to attract nocturnal bees Megalopta on guarana (Paullinia cupana) [31], and honey bees on Medicago sativa [32] and pears (Pyrus communis), where (E)-β-ocimene and lilac alcohols were also found to be attractive to bees [33]. Compounds like α-pinene and D-limonene were also found to be attractive to A. mellifera [34], with the second one identified in the A. chinensis' headspace sample.…”

Among the actinidia genus (Actinidia spp.) native to China, few species are grown commercially for their edible and healthy fruits. As they are dioecious plants, a lot of interest is paid to effective pollination and to insects as the most efficient pollinators. In this study we have concentrated on the composition of volatile compounds in male flowers of four different actinidia species (A. chinensis var. deliciosa, A. arguta, A. kolomikta and A. polygama) and on the diversity between male and female flower volatiles for the two most winter-hardy species (A. arguta and A. kolomikta) with growing commercial value. Analyses were provided using gas chromatography with mass spectrometry (GC-MS). In total, 120 compounds were found in 15 actinidia genotypes. However, the number of identified compounds varied between species. Different main compounds or groups of volatile compounds characterised flowers of every species. Smaller differences were observed between male and female flowers of the same species. Our results suggest that actinidia flowers could be attractive to pollinating insects.
