Hidden sinks: do bumblebee populations in agricultural landscapes persist because of mass-migration?

    Project: NWO project

    Project Details

    Description

    Although intensive agricultural practices continue to put bumblebee populations under pressure, some common and important crop-pollinating bumblebee species seem to be able to persist even in the most intensive agricultural landscapes. Earlier work suggests that this may be because these populations are annually supplemented by mass-migrating bumblebee queens from far-away locations, which would make current agricultural landscapes hidden population sinks. This research combines intensive field monitoring with novel molecular and isotope methods to unravel the role of mass-migration on bumblebee population dynamics in agricultural landscapes, which can improve effective pollinator conservation and food production.

    Description

    Hoewel intensieve agrarische landbouwpraktijken zorgen voor een grote druk op hommelpopulaties, lijken sommige belangrijke gewas-bestuivende hommelsoorten zelfs stand te houden in de meest intensieve agrarische landschappen. Eerder onderzoek suggereert dat dit mogelijk is omdat de populaties jaarlijks aangevuld worden door massaal trekkende hommels van verre locaties. In dat geval zouden hommelpopulaties in agrarische landschappen eigenlijk verborgen verliezers zijn. Dit onderzoek combineert innovatieve moleculaire en isotopenanalyses met intensieve monitoring om de rol van hommelmassamigratie op de populaties in agrarische landschappen te onderzoeken, en verbetert de effectieve bescherming van bestuivers en onze voedselzekerheid.
