The Hidden Diptera Diversity in Aristolochia Trap‐Flowers: Revealing the Identity of Pollinators Through Taxonomic Knowledge

open access: yesJournal of Applied Entomology, Volume 149, Issue 10, Page 1502-1512, December 2025.
ABSTRACT Although Diptera is one of the most diverse insect orders with a high potential for pollinating plants, it remains poorly studied and neglected. This is partly due to limited taxonomic efforts in species identification. For instance, despite being primary pollinators of trap flowers, species‐level identification in these systems remains scarce.

Illuminating the Dark: Using eDNA Metabarcoding to Study the Unique Ichthyofauna of the Furnas Formation Sinkholes

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
Using eDNA metabarcoding, we assessed fish diversity in isolated sinkholes in southern Brazil, uncovering signs of local extinction and species persistence. This approach offers a non‐invasive tool for biodiversity assessment and informs conservation efforts in unique karst environments.
