Cretaceous lacewing larvae with binocular vision demonstrate the convergent evolution of sophisticated simple eyes

open access: yesInsect Science, EarlyView.
We report three ca. 100 million‐year‐old lacewing larvae with extraordinarily large stemmata. One of them additionally has a very wide head, which represents a previously unknown morphology. The arrangement of the stemmata indicates stereoscopic vision in these predatory larvae.

Joint assembly and genetic mapping of the Atlantic horseshoe crab genome reveals ancient whole genome duplication [PDF]

open access: yesGigaScience 2014, 3:9, 2013
Horseshoe crabs are marine arthropods with a fossil record extending back approximately 450 million years. They exhibit remarkable morphological stability over their long evolutionary history, retaining a number of ancestral arthropod traits, and are often cited as examples of "living fossils." As arthropods, they belong to the Ecdysozoa}, an ancient ...

Ecological factors underlying the spatiotemporal dynamics in a key forest beetle pollinator Facteurs écologiques à la base de la dynamique spatio‐temporelle d'un important coléoptère forestier pollinisateur

open access: yesAgricultural and Forest Entomology, EarlyView.
Eusphalerum, an understudied beetle pollinator in North America, comprises over 50% of beetle specimens collected using flight‐intercept traps in forests across New Brunswick, Canada. In a study investigating its phenology, congeneric aggregation and population dynamics, we demonstrated that Eusphalerum exhibits unique phenology distinct from other ...

Recurrent convolutional neural networks for mandible segmentation from computed tomography [PDF]

open access: yesarXiv, 2020
Recently, accurate mandible segmentation in CT scans based on deep learning methods has attracted much attention. However, there still exist two major challenges, namely, metal artifacts among mandibles and large variations in shape or size among individuals.

Mechanical properties and cuticle organisation in mandibles are related to the task specialisation in leafcutter ants (Atta laevigata, Attini, Formicidae)

open access: yesPhysiological Entomology, EarlyView.
Task‐specialization and mandible properties: Leafcutter ants show caste‐based task division, reflected in mandible morphology and mechanical properties. Structural and mechanical analysis: The cuticle was composed of exo‐, meso‐, and endocuticle.

Gastritis over Gastrisus Sharp (Coleoptera: Staphylinidae: Xanthopygina): Resolving a major taxonomic impediment with phylogenomics

open access: yesSystematic Entomology, EarlyView.
Comprehensive phylogeny of Xanthopygina rove beetles (Coleoptera: Staphylinidae), including 30 of 33 genera, was generated by anchored hybrid enrichment of 1229 nuclear, protein‐encoding loci. We resolved nine major clades within Xanthopygina, including the new Leptodiastemus group, and successfully delineated a monophyletic concept of Gastrisus ...

Interactions between host plant quality and non‐consumptive predator effects on oviposition and larval behaviour of Plutella xylostella (Lepidoptera: Plutellidae)

open access: yesAgricultural and Forest Entomology, Volume 27, Issue 2, Page 148-159, May 2025.
Abstract The presence of predators can induce non‐consumptive effects on prey that result in subsequent changes to prey behaviour and defence. We investigate the interaction between top‐down non‐consumptive effects of various stages of the predator Coccinella septempunctata L.(Coleoptera: Coccinellidae) (larvae and adult) and bottom‐up effects of host ...

Prediction of mandibular ORN incidence from 3D radiation dose distribution maps using deep learning [PDF]

open access: yesarXiv, 2021
Background. Absorbed radiation dose to the mandible is an important risk factor in the development of mandibular osteoradionecrosis (ORN) in head and neck cancer (HNC) patients treated with radiotherapy (RT). The prediction of mandibular ORN may not only guide the RT treatment planning optimisation process but also identify which patients would benefit

Cutting the sap: First molecular phylogeny of twig‐girdler longhorn beetles (Coleoptera: Cerambycidae: Lamiinae: Onciderini) suggests shifts in host plant attack behaviours contributed to morphological evolution

open access: yesSystematic Entomology, Volume 50, Issue 2, Page 369-386, April 2025.
Onciderines originated c. 56 Ma, in the Palaeocene‐Eocene boundary, and consist of two major monophyletic lineages, here established as subtribes Hypsiomatina and Onciderina. A novel, female‐specific mechanism of attacking host plants known as girdling evolved independently and irreversibly at least five times in the onciderines.

Linking effect traits of soil fauna to processes of organic matter transformation

open access: yesFunctional Ecology, Volume 39, Issue 2, Page 446-461, February 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil organic matter (SOM) transformation processes are regulated by the activities of plants, microbes, and fauna. Compared with plants and microbes, effects of soil fauna are less understood because of their high taxonomic and functional diversity, and mix of direct ...
