Plant-Pollinator Interactions in Grasslands Established on Arable Land. [PDF]

open access: yesEcol Evol
We compared plant‐pollinator networks in newly established and old, permanent grasslands in a Central European agricultural landscape. Newly established grasslands showed higher pollinator visitation frequency and diversity per plant species, especially for solitary bees and syrphids, with a comparable network structure to old grasslands.

A supermatrix phylogeny of the world’s bees (Hymenoptera: Anthophila)

open access: yesMolecular Phylogenetics and Evolution, 2023
AbstractThe increasing availability of large phylogenies has provided new opportunities to study the evolution of species traits, their origins and diversification, and biogeography; yet, with the exception of butterflies, taxonomically well-curated phylogenies are currently lacking for major insect groups.

Sensitive Environmental DNA Methods for Low-Risk Surveillance of At-Risk Bumble Bees. [PDF]

open access: yesMol Ecol Resour
ABSTRACT Terrestrial environmental DNA (eDNA) techniques have been proposed as a means of sensitive, non‐lethal pollinator monitoring. To date, however, no studies have provided evidence that eDNA methods can achieve detection sensitivity on par with traditional pollinator surveys.

Synthesis of β(1 → 3) and β(1 → 6) galactooligosaccharides from lactose and whey using a recombinant β-galactosidase from Pantoea anthophila

open access: yesElectronic Journal of Biotechnology, 2021
Background: Milk whey, a byproduct of the dairy industry has a negative environmental impact, can be used as a raw material for added-value compounds such as galactooligosaccharides (GOS) synthesis by β-galactosidases.
