Restricted Dispersal in the Late Successional Forest Tree Species Nothofagus Pumilio: Consequences Under Global Change

open access: yesEcology and Evolution, Volume 15, Issue 5, May 2025.
We aim to uncover the current and historic effective dispersal distances and characterize fine‐scale genetic structure in the forest tree species Nothofagus pumilio. Short seed dispersal distances mean N. pumilio distribution expansion capacity may be limited, especially in the context of global change.

Phenotypic, Floristic, and Anthropogenic Drivers of the Pollen Niche of Amazonian Stingless Bees

open access: yesBiotropica, Volume 57, Issue 3, May 2025.
The pollen diversity and composition collected by Amazonian stingless bees depend on their body mass, tree composition, and urbanization. Further, bees have been collecting fewer pollen types since the 1970s. ABSTRACT Stingless bees (Apidae: Meliponini) are major pollinators in the tropics, supporting key ecosystem services.

A dataset of pollen production for 168 common flowering plants in the United Kingdom

open access: yesEcological Solutions and Evidence, Volume 6, Issue 2, April–June 2025.
In addition to nectar, pollen is an important floral resource consumed by flower‐visiting insects. This dataset provides a measure of pollen volume production per flower for 168 plant species found in the UK. Plant species vary in pollen production by a factor of more than 60,000, with Medicago lupulina (picture above) being the species with the lowest
