Influence of forest cover and sex on wing size and shape of a spider‐hunting wasp in the Brazilian Atlantic forest

open access: yesEcological Entomology, Volume 51, Issue 1, Page 165-176, February 2026.
Forest cover significantly influences the wing shape of female Trypoxylon lactitarse. Females exhibit longer and narrower wings, linked to greater flight efficiency and dispersal. Sexual dimorphism indicates that females respond differently to ecological pressures, underscoring the role of forest cover in species persistence.

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.

Pollination ecology in the tropical Andes: moving towards a cross‐scale approach

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2312-2345, December 2025.
ABSTRACT Plant–pollinator interactions structure ecological communities and represent a key component of ecosystem functioning. Pollination networks are expected to be more diverse and specialised in the tropics, but pollination ecology in these regions has been understudied in comparison to other areas.

Solitary oil‐collecting bee in cities: Habitat suitability and lack of population structuring in Centris analis

open access: yesInsect Conservation and Diversity, Volume 18, Issue 6, Page 982-996, November 2025.
Lack of genetic population structure in urban populations of Centris analis. Low morphological differentiation across four phytogeographical regions in Brazil. Monogyny‐monandry mating system in C. analis. Abstract The decline of insect populations worldwide has raised concerns about the negative impact on ecosystem services, particularly pollination ...

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.
