Urban rendezvous: Spatiotemporal overlap is more important than abundance and trait matching for urban plant–pollinator interactions

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our study shows that the generalized structure of urban plant–pollinator interactions is mirrored in the mechanisms that shape them, as interactions are governed primarily by less restrictive drivers such as abundance and spatiotemporal overlap rather than by trait matching.

Comparing GHG Emissions of Residue‐Based BECCS to Alternative Biomass Uses

open access: yesGCB Bioenergy, Volume 17, Issue 12, December 2025.
We compare the total emissions of two future BECCS plants in the Netherlands using wood and bagasse residues to the current coal‐biomass plants. Then we assess the BECCS emissions overtime compared to different uses of the same biomass wood and bagasse residues.

Local and landscape features of urban fragments determine the occurrence of stingless bees As características locais e paisagísticas dos fragmentos urbanos determinam a ocorrência de uma espécie de abelhas sem ferrão

open access: yesInsect Conservation and Diversity, Volume 18, Issue 6, Page 1027-1036, November 2025.
Both local and landscape factors associated with habitat availability and quality determine the persistence of stingless bees across fragments. Places where the species occurs have local and landscape characteristics distinctive from those where it is absent.

Beyond Deception: What Else Do Flower Wasps (Hymenoptera: Thynnidae: Thynninae) Do in Flowers Worldwide?

open access: yesJournal of Applied Entomology, Volume 149, Issue 9, Page 1351-1363, November 2025.
ABSTRACT Wasps, although less recognised as good pollinators, also feed on nectar and pollinate flowers. Specialised pollination systems, such as orchids that mimic the pheromones of female wasps to attract males, are complex and specific. This interaction occurs with some Thyninnae wasps that also visit flowers to obtain nectar and perform other ...

Integrating Population Genomics and Historical Occurrence Data to Assess the Impact of Land‐Use Changes on Centris Oil Bees in the Brazilian Cerrado

open access: yesMolecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Habitat loss and fragmentation (HLF) are among the major drivers of bee decline, yet closely related species often show contrasting responses depending on their ecological and demographic traits. The Brazilian Cerrado biodiversity hotspot experiences among the world's highest rates of HLF.

Temporal and Ontogenetic Changes in Feeding Ecology of a Characid From Karst Dolines of the Neotropics

open access: yesEcology of Freshwater Fish, Volume 34, Issue 4, October 2025.
ABSTRACT Environmental and biological factors strongly shape fish diets, yet little is known about such influences in flooded Karst Dolines of the Neotropical region. This study examined the diet of Deuterodon luetkenii and assessed its temporal and ontogenetic variation in Lagoa Misteriosa, a karstic lagoon. Fish were sampled bimonthly over 1 year and
