Handbook of protocols for standardized measurements of floral traits for pollinators in temperate communities

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 5, Page 988-1001, May 2025.
Abstract Floral traits describe organs or structures directly related to plant reproduction, and they are essential to understanding plant–pollinator interactions, notably for conservation purposes. The growth of plant trait‐based approaches lies in the availability of data shared by the international research community on dedicated platforms, as well ...

The male germ unit association is independently regulated of GUM in Arabidopsis thaliana

open access: yesPlant Direct, Volume 8, Issue 7, July 2024.
Abstract Cytoplasmic projections (CPs) formed by the generative and sperm cells link the male gametes with the vegetative cell (VC) nucleus, which are required to build the male germ unit (MGU) assemblage in the angiosperm pollen grain. As molecular and genetic controls underlying CP development and formation of the MGU are unknown, it was hypothesized

Assessing the analytical reliability of traditional and novel sampling methods for the study of flower rewards quality

open access: yesEcosphere, Volume 15, Issue 3, March 2024.
Abstract Pollinator insects are declining worldwide also due to the alteration of their diet which plays a pivotal role in influencing their health status. Despite interspecific and intraspecific diversity in the diet, pollinators completely or partly rely on pollen and nectar as food sources.

E‐PoSa: A novel and effective tool for sampling pollen directly from flowers

open access: yesMethods in Ecology and Evolution, Volume 15, Issue 1, Page 51-59, January 2024.
Abstract Pollinator insects are declining worldwide, also due to the alteration of their diet with severe implications on their health status. Pollinators diet relies mainly on flower rewards (i.e. pollen and nectar), and a precise characterization of their chemical composition is crucial in defining pollinators' nutritional ecology.
