A revised classification of the assassin bugs (Hemiptera: Heteroptera: Reduviidae) based on combined analysis of phylogenomic and morphological data

open access: yesSystematic Entomology, Volume 50, Issue 1, Page 102-138, January 2025.
This study produces the first combined morphological and molecular phylogenetic analysis for Reduviidae and reveals synapomorphies and diagnostic traits for clades at the ranks of subfamilies and tribes. Based on our resulting robust phylogenetic reconstructions and subsequent optimization of morphological character information, we propose a ...

Low-latency Visual Previews of Large Synchrotron Micro-CT Datasets [PDF]

open access: yesarXiv, 2023
The unprecedented rate at which synchrotron radiation facilities are producing micro-computed (micro-CT) datasets has resulted in an overwhelming amount of data that scientists struggle to browse and interact with in real-time. Thousands of arthropods are scanned into micro-CT within the NOVA project, producing a large collection of gigabyte-sized ...

A new exceptionally preserved sawfly fossil (Hymenoptera: Pergidae) and an evaluation of its utility for divergence time estimation and biogeography

open access: yesSystematic Entomology, Volume 50, Issue 1, Page 237-251, January 2025.
We describe the first Australian Pergidae fossil species, Baladi warru, from McGraths Flat, a newly discovered Miocene Konservat‐Lagerstätte in Australia. The specimen contains pollen grains from Quintianapolis that were imaged with high‐resolution using SEM.

Wear Mechanics of the Female Locust Digging Valves: The “Good Enough” Principle

open access: yesAdvanced Functional Materials, Volume 34, Issue 48, November 26, 2024.
Adult female desert locusts dig underground roughly three‐four times in their lives to lay their eggs, using the two pairs of oviposition valves at the tip of the female's abdomen. This study highlights the evolutionary adaptation of the valve materials to their specific function, suggesting a trade‐off between energetic investment and the sufficient ...

Robust and fully automated segmentation of mandible from CT scans [PDF]

open access: yesarXiv, 2017
Mandible bone segmentation from computed tomography (CT) scans is challenging due to mandible's structural irregularities, complex shape patterns, and lack of contrast in joints. Furthermore, connections of teeth to mandible and mandible to remaining parts of the skull make it extremely difficult to identify mandible boundary automatically.

The Detri2match conceptual framework: Matching detritivore and detritus traits to unravel consumption rules in a context of decomposition

open access: yesFunctional Ecology, Volume 38, Issue 10, Page 2084-2098, October 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract From soil to freshwater ecosystems, decomposition can be conceived as the result of interactions between organic matter and a diversity of organisms. This function is driven in part by detritivores, invertebrates that feed on detritus or graze on its associated microbes

Plant Silicon Defences Suppress Herbivore Performance, but Mode of Feeding Is Key

open access: yesEcology Letters, Volume 27, Issue 10, October 2024.
The performance of herbivores is influenced by the nutritional and defensive traits of plants, with biogenic silicon being a common anti‐herbivore defence, especially in grasses. Our meta‐analyses of 150 studies revealed that higher silicon levels in plants led to a 33% decline in overall herbivore performance, with chewing herbivores being more ...

Inference and model determination for Temperature-Driven non-linear Ecological Models [PDF]

open access: yesarXiv, 2021
This paper is concerned with a contemporary Bayesian approach to the effect of temperature on developmental rates. We develop statistical methods using recent computational tools to model four commonly used ecological non-linear mathematical curves that describe arthropods' developmental rates. Such models address the effect of temperature fluctuations

The evolutionary history of Coleoptera (Insecta) in the late Palaeozoic and the Mesozoic

open access: yesSystematic Entomology, Volume 49, Issue 3, Page 355-388, July 2024.
Structural transformations of the elytra and abdomen played a major role in the early beetle evolution in the Permian. Polyphaga appear late in the fossil record, with only a few fossils of Elateriformia in the Late Triassic. Several factors were involved in the enormous diversification of beetles in the Cretaceous but evolutionary interactions with ...

3D segmentation of mandible from multisectional CT scans by convolutional neural networks [PDF]

open access: yesarXiv, 2018
Segmentation of mandibles in CT scans during virtual surgical planning is crucial for 3D surgical planning in order to obtain a detailed surface representation of the patients bone. Automatic segmentation of mandibles in CT scans is a challenging task due to large variation in their shape and size between individuals. In order to address this challenge
