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

open access: yesJournal 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 ...

Multiple hybridization events and repeated evolution of homoeologue expression bias in parthenogenetic, polyploid New Zealand stick insects

open access: yesMolecular Ecology, EarlyView.
Abstract During hybrid speciation, homoeologues combine in a single genome. Homoeologue expression bias (HEB) occurs when one homoeologue has higher gene expression than another. HEB has been well characterized in plants but rarely investigated in animals, especially invertebrates.

Chemical ecology of symbioses in cycads, an ancient plant lineage

open access: yesNew Phytologist, EarlyView.
Summary Cycads are an ancient lineage of gymnosperms that maintain a plethora of symbiotic associations from across the tree of life. They have myriad morphological, structural, physiological, chemical, and behavioral adaptations that position them as a unique system to study the evolution, ecology, and mechanism of symbiosis.

‘Retournement’ of the aedeagus in Curculionidae (Coleoptera, Curculionoidea) [PDF]

open access: yes, 2013
Retournement or turning of the aedeagus about its longitudinal axis through about 180o during development is known in Chrysomeloidea (Coleoptera). This change in the orientation of the organ may be observed during the postembryonic development.

ON A RECENT SPECULATION AS TO RANK IN INSECTA [PDF]

open access: yesThe Canadian Entomologist, 1882
The reader will have noticed, in the June number of the Canadian Entomologist, a paper on the “Physiological Arrangement of Insects.” The author there places the Orthoptera first in this list, owing to the presence of auditory organs and well developed eyes.

The effect of size on mate selection, fecundity and survival in Culex pipiens mosquitoes

open access: yesPhysiological Entomology, EarlyView.
Larval diet affects male and female adult size, female fecundity and female survival. Large non‐blood–fed females lived longer than small non‐blood–fed females. Mate size did not influence mating rate (insemination status). Even though larger females are more fit, males mated equally to large and small females when given the option. Blood feeding has a

Performance of computer vision algorithms for fine-grained classification using crowdsourced insect images [PDF]

open access: yesarXiv
With fine-grained classification, we identify unique characteristics to distinguish among classes of the same super-class. We are focusing on species recognition in Insecta, as they are critical for biodiversity monitoring and at the base of many ecosystems. With citizen science campaigns, billions of images are collected in the wild.
