From cities to refuges for pollinators: Urban practices for enhancing pollinator habitats in changing landscapes

open access: yesJournal of Applied Ecology, EarlyView.
A framework for the support of pollinators in urban areas is developed here, based on five pillars: nesting, flower resources, artificial support, management and society acceptance, with additional key elements from science and society. Society should incorporate strategies for pollinators as in this framework by means of co‐planning with stakeholders,

Temperature and precipitation explain species‐specific phenological patterns in five native California milkweed species (Asclepias spp.)

open access: yesJournal of Ecology, EarlyView.
Combining analytical approaches for studying phenology using observation datasets with the wide availability of observational data from participatory science sources offers an exciting possibility to rapidly generate hypotheses about how organisms' phenology may react to novel cue combinations under global change, and how these reactions may differ ...

High migratory potential of fall armyworm in West Africa despite stable temperatures and widely available year‐round habitats

open access: yesInsect Science, EarlyView.
Despite the minimal annual temperature variation and the widespread distribution of potential year‐round habitats in Ghana, the migratory potential of the local fall armyworm remains strong and is indistinguishable from that of the fall armyworm in China, which undergo seasonal migration.
