Assessing the role of dispersed floralresources for managed bees in providingsupporting ecosystem services for croppollination [PDF]
, 2018 Most pollination ecosystem services studies have focussed on wild pollinators and their dependence on natural floral resources adjacent to crop fields. However, managed pollinators depend on a mixture of floral resources that are spatially separated from

Global Trends in the Status of Bird and Mammal Pollinators [PDF]
, 2015 Biodiversity is declining, with direct and indirect effects on ecosystem func-tions and services that are poorly quantified. Here, we develop the first globalassessment of trends in pollinators, focusing on pollinating birds and mam-mals.
