Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems

Entomologia Experimentalis et Applicata, EarlyView.
We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.

Floral adaptation and modular trait evolution associated with a shift from bee to hummingbird pollination

Plant Biology, EarlyView.
By comparing floral trait variation, integration and modularity in two sister species of Neotropical Costus with a pollination shift, we show that, despite pollination syndrome divergence, both species exhibit low floral variation and functional modularity, consistent with pollinator‐driven selection on traits mediating pollen transfer efficiency and ...

A dual pollination strategy combining perfume attraction and food deception in Galeandra blanchetii E.S. Rand (Orchidaceae)

Plant Biology, EarlyView.
Galeandra blanchetii exhibits a dual‐attraction strategy: male euglossine bees are lured by floral scents as a resource, while both sexes are deceived by non‐existent nectar. Pollination only occurs when bees enter the spur to search for nectar, highlighting an evolutionary transition towards the perfume flower syndrome in Catasetinae.

Lipidomics of orchid seeds: from development to storage

Plant Biology, EarlyView.
The study tracked lipid changes from pollination to storage in two orchid species. Although both were desiccation‐tolerant and storable, differences in saturated and unsaturated fatty acid proportions during development led to different moisture contents and germination capacities.

Simultaneous Inference of Flora‐Wide Nuclear and Plastid Phylogenies Using Angiosperms353 Sequence Capture Data

Molecular Ecology Resources, Volume 26, Issue 7, October 2026.
ABSTRACT Accurate knowledge of phylogenetic relationships and divergence time among plant species composing a regional flora is crucial for understanding the origin of the biodiversity patterns we observe today. Despite advances in phylogenomics, resources available for reconstructing regional phylogenies are still largely incomplete and poorly ...

Underground allies: Mycorrhizal flexibility facilitates orchid occurrence in post‐mining landscapes

Plant Biology, Volume 28, Issue 6, Page 1899-1911, October 2026.
Epipactis helleborine associates with largely habitat‐specific fungal communities, with limited overlap between mining and woodland sites, yet maintains comparable genetic diversity across habitats. These results highlight the role of mycorrhizal flexibility in enabling habitat shifts and expanding ecological niches in human‐altered landscapes ...
