Plant traits, environmental factors, and pollinator visitation in winter-flowering Helleborus foetidus (Ranunculaceae).
BACKGROUND AND AIMS This study examined the effect of plant traits and environmental factors on pollinator visitation in the winter-flowering Helleborus foetidus (Ranunculaceae) in three distant regions in the Iberian Peninsula. METHODS Geographical variation in floral visitor assemblage, plant traits and environmental factors were analysed during the flowering season. KEY RESULTS Differenc...
متن کاملVisiting insect diversity and visitation rates for two globally-imperiled plant species in Colorado’s Mosquito Range
Ipomopsis globularis (Globe gilia), and Saussurea weberi (Weber's saussurea) are globally imperiled plant species known only from geographically restricted areas in alpine habitats of the Rocky Mountains. These species were observed in the Mosquito Range of Colorado to determine the diversity of insect visitors (potential pollinators) and approximate insect visitation rates. Ipomopsis globulari...
متن کاملPhylogeny and reclassification of Aconitum subgenus Lycoctonum (Ranunculaceae)
Phylogenetic analyses were performed using multiple nuclear (ITS and ETS) and chloroplast regions (ndhF-trnL, psbA-trnH, psbD-trnT, and trnT-trnL) to test the monophyly of Aconitum subgen. Lycoctonum (Ranunculaceae) and reconstruct the phylogenetic relationships within the subgenus. The subgenus as currently circumscribed is revealed to be polyphyletic. To achieve its monophyly, sect. Galeata a...
متن کاملLinking pollinator visitation rate and pollen receipt.
The majority of flowering plants require animals for pollination, a critical ecosystem service in natural and agricultural systems. However, quantifying useful estimates of pollinator visitation rates can be nearly impossible when pollinator visitation is infrequent. We examined the utility of an indirect measure of pollinator visitation, namely pollen receipt by flowers, using the hummingbird-...
متن کاملFlowering Dynamics and Pollinator Visitation of Oilseed Echium (Echium plantagineum)
Echium (Echium plantagineum L.) is an alternative oilseed crop in summer-wet temperate regions that provides floral resources to pollinators. Its seed oil is rich in omega-3 fatty acids, such as stearidonic acid, which is desired highly by the cosmetic industry. Seeds were sown in field plots over three years in western Minnesota in spring (early-sown) or early summer (late-sown), and flower ab...
