The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Climate Predicts UV Floral Pattern Size, Anthocyanin Concentration, and Pollen Performance in Clarkia unguiculata

open access: yesFrontiers in Plant Science, 2020
Given that flower size and pigmentation can mediate plant–pollinator interactions, many studies have focused on pollinator-driven selection on these floral traits.

The pistil as a traffic light: Yellow‐to‐red color change likely influences pollinator visitation patterns in Saxifraga fortunei (Saxifragaceae)

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...

Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

open access: yesPest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

Among-population variation in microbial community structure in the floral nectar of the bee-pollinated forest herb Pulmonaria officinalis L.

open access: yesPLoS ONE, 2013
BackgroundMicrobial communities in floral nectar have been shown to be characterized by low levels of species diversity, yet little is known about among-plant population variation in microbial community composition.Methodology/principal findingsWe ...

Nectar Theft and Floral Ant-Repellence: A Link between Nectar Volume and Ant-Repellent Traits?

open access: yesPLoS ONE, 2012
As flower visitors, ants rarely benefit a plant. They are poor pollinators, and can also disrupt pollination by deterring other flower visitors, or by stealing nectar. Some plant species therefore possess floral ant-repelling traits. But why do particular species have such traits when others do not?

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

open access: yesPest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Floral nectar production in Helleborus foetidus: an ultrastructural study

open access: yesBotany, 2012
The floral nectaries of Helleborus foetidus L. were studied using scanning and transmission electron microscopy, as well as light microscopy. Nectaries are tubular and consist of an external epidermis, a photosynthesizing parenchyma, large branches of vascular tissue, a nectar-producing parenchyma, and an internal epidermis.
