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

open access: yesEntomologia 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.

Image_3_Plastome phylogenomics and biogeography of the subfam. Polygonoideae (Polygonaceae).tif

open access: yes, 2022
Polygonaceae has a complex taxonomic history, although a few studies using plastid or nuclear DNA fragments have explored relationships within this family, intrafamilial relationships remain controversial.

Evolution in arid environments: the role of betalains, succulence, and medullary bundles

open access: yesNew Phytologist, EarlyView.
Overview of the study system. Summary The flowering plant clade Caryophyllales includes many succulent species that grow in drought conditions. Many Caryophyllales species also have betalain pigmentation and medullary bundles, both of which have been linked to stress tolerance, albeit with less precise functional characterisation.

Quantitative Structure–Activity Relationship Approaches for Exploring the Anticancer Potential of Flavonoids

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
QSAR‐based analysis of flavonoids to identify structural determinants of anticancer activity and prioritize promising candidates. ABSTRACT Flavonoids are structurally diverse polyphenolic compounds widely distributed in fruits, vegetables, grains, and beverages, with considerable potential as anticancer agents.

Global‐Scale Patterns of Host Transitions Suggest Contrasting Levels of Specialization Within Rhizoctonia solani

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
We combined a global rDNA‐ITS dataset with TEF‐1α sequences and newly sequenced isolates to examine phylogenetic signal, host associations, and population structure in the soil‐borne pathogen Rhizoctonia solani. Most anastomosis groups formed well‐supported clades, and host‐associated patterns corresponded more strongly with genetic structure than ...

Trophic and Environmental Generalists Maintain Pollinator Network Functional Continuity by Switching Modules Through Time

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
By linking niche breadth to temporal pollination networks, we move beyond documenting dynamics to reveal the functional processes that maintain network persistence. Our findings directly identify the versatile generalist species that are vital for stability, offering clear priorities for conservation in a changing climate.
