Factors Influencing the Reproductive Ability of Male Bees: Current Knowledge and Further Directions

open access: yesInsects, 2021
Bumblebees and honeybees are very important pollinators and play a vital role in agricultural and natural ecosystems. The quality of their colonies is determined by the queens and the reproductive drones of mother colonies, and mated drones transmit ...

Pollination Services of Mango Flower Pollinators [PDF]

open access: yesJournal of Insect Science, 2015
Measuring wild pollinator services in agricultural production is very important in the context of sustainable management. In this study, we estimated the contribution of native pollinators to mango fruit set production of two mango cultivars Mangifera indica (L). cv. 'Sala' and 'Chok Anan'. Visitation rates of pollinators on mango flowers and number of

A critical analysis of the potential for EU Common Agricultural Policy measures to support wild pollinators on farmland [PDF]

open access: yes, 2020
1. Agricultural intensification and associated loss of high‐quality habitats are key drivers of insect pollinator declines. With the aim of decreasing the environmental impact of agriculture, the 2014 EU Common Agricultural Policy (CAP) defined a set of ...

The effect of the brood and the queen on early gene expression in bumble bee workers' brains

open access: yesScientific Reports, 2022
Worker reproduction in social insects is often regulated by the queen, but can be regulated by the brood and nestmates, who may use different mechanisms to induce the same outcomes in subordinates. Analysis of brain gene expression patterns in bumble bee

A review of pollinator conservation and management on infrastructure supporting rights-of-way

open access: yesJournal of Pollination Ecology, 2012
Early successional landscapes along or adjacent to infrastructure installations have been highlighted as potential pollinator conservation zones that provide environmental benefits and ameliorate some of the negative impacts of wildland conversion ...

Mating Stimulates the Immune Response and Sperm Storage-Related Genes Expression in Spermathecae of Bumblebee (Bombus terrestris) Queen

open access: yesFrontiers in Genetics, 2021
Bumblebee queens have remarkable spermathecae that store sperm for year-round reproduction. The spermathecal gland is regarded as a secretory organ that could benefit sperm storage.

Potential landscape-scale pollinator networks across Great Britain: structure, stability and influence of agricultural land cover [PDF]

open access: yes, 2018
Understanding spatial variation in the structure and stability of plant-pollinator networks, and their relationship with anthropogenic drivers, is key to maintaining pollination services and mitigating declines.

Why flower visitation is a poor proxy for pollination : measuring single-visit pollen deposition, with implications for pollination networks and conservation [PDF]

open access: yes, 2013
Funding: NERC studentship (CK - NE/H527291/1), St Andrews Scholarship (GB)Summary The relative importance of specialized and generalized plant-pollinator relationships is contentious, yet analyses usually avoid direct measures of pollinator quality ...
