Mapping the local dielectric constant of a biological nanostructured system
Beilstein Journal of Nanotechnology, 2021 The aim of this work is to determine the varying dielectric constant of a biological nanostructured system via electrostatic force microscopy (EFM) and to show how this method is useful to study natural photonic crystals.

Thermal Plasticity is Regulated by a Key MicroRNA During Range Expansion of an Invasive Fruit Fly
Advanced Science, Volume 13, Issue 23, 23 April 2026.Populations at the invasion front of Bactrocera dorsalis adapt through reduced phenotypic and gene expression plasticity, a phenomenon likely to be driven by genetic assimilation. We identify a key miRNA‐mediated regulatory axis, in which miR‐276b post‐transcriptionally represses thw, a conserved chitin‐binding gene critical to the cold‐tolerance ...

Molecular bases of insect odorant receptor function: specificity and evolution
Biological Reviews, Volume 101, Issue 2, Page 1036-1049, April 2026.ABSTRACT Insect odorant receptors (ORs) are a class of chemoreceptors that insects use to detect volatile cues in their environment. In recent years, major advances in the field of structural biology have made it possible to obtain the first structures of insect ORs.

Allozyme and mitochondrial DNA variability within the New Zealand damselfly genera Xanthocnemis, Austrolestes, and Ischnura (Odonata) [PDF]
, 2007 We collected larval damselflies from 17 sites in the North, South and Chatham Islands, and tested the hypotheses that: (1) genetic markers (e.g., allozymes, mtDNA) would successfully ¬discriminate taxa; and (2) the dispersal capabilities of adult ...

Evaluating Conservation Corridor Success for Rare and Common Dragonflies Using Zeta Diversity
Ecology and Evolution, Volume 16, Issue 4, April 2026.This study applied the zeta diversity framework to evaluate how conservation corridors in South African timber plantations impact dragonfly assemblages, finding that corridors function similarly to natural habitats. The research findings showed that dragonfly species richness was higher in corridors than in natural areas, consistently declining with ...
