Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

Entomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

A new species of Pnigalio (Hymenoptera, Eulophidae) parasitizing Eriocrania semipurpurella alpina (Lepidoptera, Eriocraniidae) in China, with its biology and a key to Chinese known species

ZooKeys, 2017
A new species of Eulophinae, Pnigalio eriocraniae Li & Yang, sp. n., is described and illustrated. This new species is a larval ectoparasitoid of Eriocrania semipurpurella alpina Xu (Lepidoptera, Eriocraniidae), a leaf miner in birch trees ...

Life‐History Traits and Overwintering of Actia interrupta (Diptera: Tachinidae), a Larval Parasitoid of Choristoneura fumiferana (Lepidoptera: Tortricidae)

Entomologia Experimentalis et Applicata, EarlyView.
Actia interrupta is a larval tachinid parasitoid that plays a key role in regulating low‐density populations of the eastern spruce budworm. We describe its immature stages, life‐history traits, host‐searching behavior, development, and confirm its larviparous reproductive strategy.

Birch Leaves as a Minefield: Do Trichomes Mediate Neonate Caterpillar Site Selection?

Entomologia Experimentalis et Applicata, EarlyView.
We investigated whether neonate Drepana arcuata caterpillars select leaf sites based on trichome distribution. Specifically, we assessed where larvae establish on leaves, quantified trichome distribution on leaves, and tested whether neonates avoid leaf trichomes. Neonates preferentially established and fed on areas with fewer trichomes, especially the

A novel method based on high‐resolution imaging spectroscopy to predict fine‐root traits and the economics space of fresh tree roots

New Phytologist, EarlyView.
Maps of the estimated root nitrogen concentration in the < 0.5‐mm‐diameter classes of 20 woody species based on the imaging spectroscopy using the shortwave infrared spectral region. Summary Tree fine‐root morphological, anatomical, and chemical traits are important to reflect belowground resource acquisition strategies to support tree growth, but ...

Biochemical and systematic study of the genus Betula L.

Acta Societatis Botanicorum Poloniae, 2014
The division of the genus Betula L. accomplished on the basis of the flavonoid composition characteristic for the particular species; the proposed systematic classification also takes the chromosome number and geographical distribution into account.

Tandem Duplication‐Driven Neofunctionalization of UDP‐Glycosyltransferases Shapes the Diversification of Triterpenoid Saponins in the Cucurbitaceae

Advanced Science, Volume 13, Issue 51, 14 September 2026.
We present a chromosome‐level genome assembly of Siraitia grosvenorii and, through comparative genomics, uncover a conserved UGT73 tandem array driving triterpenoid saponin diversification in Cucurbitaceae. Crystalized SgUGT73AM30 further reveals the regioselectivity mechanism underlying its catalytic activity.

Comparative Flower and Inflorescence Organogenesis among Genera of Betulaceae: Implications for Phylogenetic Relationships

, 2017
Betulaceae have simple flowers but complex inflorescences. Recent phylogenetic analyses using molecular data have produced robust phylogenetic trees of Betulaceae.
