Evolution: The origin of insect wings revisited
The evolution of wings and flight was key for the rise of insects. A new study finds that lateral extensions on the abdominal segments of primitive insect nymphs are the serial homologues of wings and probably helped control gliding.Ross, Andrew J

Cranial volume and palate length of cats, Felis spp., under domestication, hybridization and in wild populations
Reduced brain size, compared with wild individuals, is argued to be a key characteristic of domesticated mammal species, and often cited as a key component of a putative ‘domestication syndrome’. However, brain size comparisons are often based on old, inaccessible literature and in some cases drew comparisons between domestic animals...Lesch, Raffaela ; Kitchener, Andrew C ; Hantke, Georg ; Kotrschal, Kurt ; Fitch, W Tecumseh

Sympiesis notata (Hymenoptera: Chalcidoidea: Eulophidae), a gregarious parasitoid of Hesperiidae (Lepidoptera), and some records of other Chalcidoidea associated with skipper butterflies in the Western Palaearctic
Sympiesis notata is a gregarious ectoparasitoid of skipper butterfly caterpillars. Other Lepidoptera larvae in leaf mines and leaf folds are attacked by the same morphospecies, but on these smaller hosts S. notata is usually a solitary parasitoid. Other Chalcidoidea recorded as reared from hesperiid hosts are mostly species of Brachymeria...Askew, Richard ; Shaw, Mark R

Genetic examination of historical North Atlantic right whale (Eubalaena glacialis) bone specimens from the eastern North Atlantic: Insights into species history, transoceanic population structure, and genetic diversity
Species monitoring and conservation is increasingly challenging under current climate change scenarios. For the North Atlantic right whale (Eubalaena glacialis) this challenge is heightened by the added effects of complicated and uncertain past species demography. Right whales once had a much wider distribution across the North Atlantic Ocean, although the...Frasier, Brenna A ; Springate, Leah ; Frasier, Timothy R ; Brewington, Seth ; Carruthers, Martin …

Abnormal (Hydroxy)proline Deuterium Content Redefines Hydrogen Chemical Mass
Analyzing the δ2H values in individual amino acids of proteins extracted from vertebrates, we unexpectedly found in some samples, notably bone collagen from seals, more than twice as much deuterium in proline and hydroxyproline residues than in seawater. This corresponds to at least 4 times higher δ2H than in any...Gharibi, Hassan ; Chernobrovkin, Alexey L ; Eriksson, Gunilla ; Saei, Amir Ata ; Timmons, Zena …

A new genus and species of gall midges the tribe Winnertziini (Diptera, Cecidomyiidae, Porricondylinae) from lower Eocene Fushun amber from China
The new taxon, Fushuniola mai Fedotova & Perkovsky, gen. et sp. nov., is described from a single female from the lower Eocene (Ypresian) Fushun amber from China. This is the second record of Cecidomyiidae known from Fushun amber. The first record is Cecidomyia bujunensis Naora. The new species is characterized... -

An annotated list of Lonchaeidae (Diptera) from China, Cambodia and Vietnam with description of a new species
A preliminary list of 14 species of the family Lonchaeidae recorded from Cambodia, China and Vietnam is given. Silba filamenta sp. n. is described from North-East China. New country records are provided for three species of Lonchaea Fallén, 1820 and two species of Silba Macquart, 1851.MacGowan, Iain ; Barták, M ; Honorary Research Associate, National Museums of Scotland, Collection Centre, 242 West Granton Road, Edinburgh EH5 1JA, United Kingdom

Supplement to the Burmese (Myanmar) amber checklist and bibliography, 2021
This is a supplement to the Burmese (Myanmar) amber checklist and bibliography covering taxa described or recorded during 2021, plus a few earlier records that were missed previously. Up to the end of 2021, 2,198 species were recorded from Kachin amber of which 337 were named in 2021. Five species...Ross, Andrew J

Take to the Skye: New pterosaur discovery
A recent spectacular find on the Isle of Skye shines new light on pterosaurs of the Jurassic period. Our Keeper of Natural Sciences Nick Fraser tells us more about this discovery, Skye’s fossil riches and the people bringing them to light, both in the past and today.Fraser, Nicholas C

Genetic integrity of European wildcats: Variation across biomes mandates geographically tailored conservation strategies
Hybridisation between domestic and wild taxa can pose severe threats to wildlife conservation, and human-induced hybridisation, often linked to species' introductions and habitat degradation, may promote reproductive opportunities between species for which natural interbreeding would be highly unlikely. Using a biome-specific approach, we examine the effects of a suite of...Protected area management, Biomes, Felis silvestris, Conservation, and Hybridisation
