ABSTRACT The Asian hornet (Vespa velutina nigrithorax) poses a significant threat to the beekeeping industry. Using an experimental apiary of 36 hives, we simultaneously evaluated the effectiveness of two mitigation measures—muzzles and electric harps—in reducing the impact of Asian hornets on honey bee colonies.

The power of ionic movements in plants
Summary The movement of ion‐driven electrogenic events known as plant action potentials in the Venus flytrap Dionaea muscipula has first been recognized in Darwin's time. Besides electrophysiological techniques making use of current‐ and voltage‐recording electrodes, today an ever‐growing spectrum of tools has become available, that report online ...

Summary The Grant‐Stebbins model predicts that a plant species encountering different pollinators across its range may undergo local adaptation and, subsequently, ecological speciation. We tested whether this could explain the origin of Aeschynanthus acuminatus (Gesneriaceae), a species phylogenetically derived from sunbird specialist ancestors.

Bee Pollen Flavonoids as a Therapeutic Agent in Allergic and Immunological Disorders
Bee pollen grains, as the male reproductive part of seed-bearing plants contain considerable concentrations of various phytochemicals and nutrients. Since antiquity, people throughout the world used pollens to cure colds, flu, ulcers, premature aging ...

ABSTRACT Anthocyanins, a group of secondary metabolites synthesised in the phenylpropanoid pathway, largely determine the peel colour of fleshy fruits, but it is not known if their synthesis is linked to vacuolar malate accumulation that underlies fruit acidity.

ABSTRACT In animal‐pollinated plants, pollen dispersal depends on several plant and animal characteristics that can influence the paternal success of a plant. Paternal success affects the genetic contribution of a genotype to the next generation, which is relevant to plant breeding.

The Lauxaniid fly Incurviseta cf. maculifrons (Malloch, 1925) is a locally abundant but poorly understood flower visitor in the Australian Alpine. We describe the flower visitation, pollen transport, pollen diet and mouthpart morphology of I. cf. maculifrons using field observations, pollen analyses and scanning electron microscopy. I. cf.
