Pollen foraging preferences in honey bees and the nutrient profiles of the pollen

open access: yesScientific Reports
Honey bees are important insect pollinators that provide critical pollination services to fruit and nut crops in the US. They face challenges likely due to pressures associated with agricultural intensification related habitat loss.

Pollen Release Dynamics and Daily Patterns of Pollen-Collecting Activity of Honeybee Apis mellifera and Bumblebee Bombus lantschouensis in Solar Greenhouse

open access: yesInsects, 2019
Pollen is important not only for pollination and fertilization of plants, but also for colony development of bee pollinators. Anther dehiscence determines the available pollen that can be collected by foragers.

Guidelines for Scale Development and Validation

open access: yesJournal of Consumer Behaviour, EarlyView.
ABSTRACT Scales, serving as measurement instruments composed of carefully designed items intended to capture latent constructs, play a critical role in advancing consumer theory and marketing practice. Yet, developing and validating scales poses a formidable challenge due to the diverse methods required to ensure rigor and robustness.

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana

open access: yesCytoskeleton, EarlyView.
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

Exploring Biodiversity through the Lens of Knautia arvensis Pollinators: Knautia Pollinator Walks as a Monitoring Method

open access: yesInsects
Declining populations of native pollinators, especially wild bees, underline the urgent need for effective monitoring within agricultural ecosystems. This study aims to (i) establish the ‘Knautia Pollinator Walk’ as an innovative pollinator monitoring ...

The scaling of seed‐dispersal specialization in interaction networks across levels of organization

open access: yesEcography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

The Role of European Union (EU) Metagovernance in Supporting the Voluntary and Community Sector in Northern Ireland

open access: yesEuropean Policy Analysis, EarlyView.
ABSTRACT This article argues that European Union (EU) peacebuilding scholarship can benefit from organizational research on the socio‐spatial dynamics of policy implementation. It introduces a strategic‐relational heuristic to address two key gaps: the marginalization of grassroots agency in spatial analyses and the separation of strategy from ...
