Ecological Niche Adaptations Influence Transposable Element Dynamics in Pollinating and Non‐Pollinating Fig Wasps

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
The influence of ecological niches on transposable element (TE) dynamics, particularly in mutualistic relationships, remains understudied. This research reveals that non‐pollinating fig wasps (NPFWs) have “aggressive,” expansion‐driven TE landscapes with active insertions, contrasting with the stable, “dormant” TE profiles in pollinators.

Poor control of the horse chestnut leafminer, Cameraria ohridella (Lepidoptera: Gracillariidae), by native European parasitoids: a synchronisation problem

open access: yesEuropean Journal of Entomology, 2004
Horse chestnut trees in many regions of Europe have suffered from epidemic infestations of C. ohridella for more than ten years. There has been no obvious decrease in the infestation level anywhere on the continent. One reason is, that the native natural
