Mechanisms of eye development and evolution of the arthropod visual system: The lateral eyes of myriapoda are not modified insect ommatidia [PDF]

, 2007
The lateral eyes of Crustacea and Insecta consist of many single optical units, the ommatidia, that are composed of a small, strictly determined and evolutionarily conserved set of cells. In contrast, the eyes of Myriapoda (millipedes and centipedes) are

Population genomic analysis of Mahoenui giant wētā (Deinacrida mahoenui) reveals minimal reduction in genomic diversity following translocation

Insect Conservation and Diversity, EarlyView.
The Mahoenui giant wētā is an Aotearoa New Zealand endemic insect of conservation concern, having been extirpated from the majority of its natural range before rediscovery in the 1960s. We assess the genetic impacts of a translocation from the remaining population in the Mahoenui Giant Wētā Scientific Reserve to establish a new population on Mahurangi ...

Do functional traits improve prediction of predation rates for a disparate group of aphid predators? [PDF]

, 2008
Aphid predators are a systematically disparate group of arthropods united on the basis that they consume aphids as part of their diet. In Europe, this group includes Araneae, Opiliones, Heteroptera, chrysopids, Forficulina, syrphid larvae, carabids ...

The Early Evolution of Biting–Chewing Performance in Hexapoda [PDF]

, 2019
Insects show a plethora of different mandible shapes. It was advocated that these mandible shapes are mainly a function of different feeding habits. This hypothesis was tested on a larger sampling of non-holometabolan biting–chewing insects with additional tests to understand the interplay of mandible function, feeding guild, and phylogeny. The results

The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach

Insect Molecular Biology, EarlyView.
Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce

A checklist of subterranean arthropods of Iran

Subterranean Biology, 2017
Understanding subterranean biodiversity is important, yet vast regions of the world remain poorly explored. Here, we provide the first step towards cataloguing the subterranean arthropods of Iran. After review and analysis of the available literature and

Specialist or generalist? Feeding ecology of the Malagasy poison frog Mantella aurantiaca [PDF]

, 2007
We studied the diet of a population of free-ranging Mantella aurantiaca, an alkaloid-containing poison frog from Madagascar. As in other poison frogs, this species is thought to sequester alkaloids from arthropod prey.

Morphological and metabarcoding dietary analysis of the cunner wrasse (Tautogolabrus adspersus) revealed significant regional variation, with large overlap between its common prey species and biofouling animals living on salmonid sea cages

Journal of Fish Biology, EarlyView.
Abstract The stomach‐less cunner wrasse (Tautogolabrus adspersus) has been experimentally used as a biological control agent for salmon lice that infest Atlantic salmon (Salmo salar) and to remove biofouling inside sea cages. The cunner demonstrates a strong population structure, suggesting that its diet, and therefore its usefulness for biological ...
