Assessing pathogen risk for wild bumblebees (Bombus spp., Apidae) in Canada

open access: yesConservation Science and Practice, EarlyView.
Pathogen spillover poses a significant threat to wild bumble bees (Bombus spp.) in Canada. Our study maps areas of overlap between high conservation priority regions for bumble bees and regions of pathogen spillover risk from managed bees, incorporating uncertainty in pathogen prevalence.

Business forms and business performance in UK manufacturing 1871–81

open access: yesThe Economic History Review, EarlyView.
Abstract We explore which business forms were predominant in the later Victorian economy and why some forms were more effective among large British manufacturing firms during this period. With a dataset of 483 manufacturing firms in 1881 that either employed at least 1000 or had done so a decade earlier, we find that the great majority were ...

Improved Precision and Reference Materials for Stable Carbon Isotope Measurement in Basaltic Glasses using Secondary Ion Mass Spectrometry

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points High‐precision measurement results for δ13C in basaltic glasses were achieved down to 25 μg g‐1 CO2 using a refined measurement procedure via large‐geometry SIMS. Three new hydrous basaltic glasses (ETNA24, ETNA32, ETNA36) were established as reference materials.
