Oikos, Volume 2026, Issue 2, February 2026.Urbanisation is a major driver of environmental change, reshaping ecological and evolutionary processes. Urban‐driven phenotypic differences are increasingly documented, but the underlying role of selection is still understudied. One pattern is the consistent reduction of carotenoid‐based plumage pigmentation in city birds.

SYNCAS‐mediated CRISPR‐Cas9 genome editing in the Jewel wasp, Nasonia vitripennis
Insect Molecular Biology, Volume 35, Issue 1, Page 48-55, February 2026.Maternal injection of Cas9 RNP together with BAPC and saponins (SYNCAS) results in efficient gene editing of Nasonia vitripennis offspring. The timing of injection and egg collection is important for maximising efficiency and reducing screening effort.

The Influence of Ethoxyquin and Sodium Bicarbonate on Egg Yolk Pigmentation
Poultry Science, 1972 Abstract Each of four diets containing no additive, .0125% ethoxyquin, .325% sodium bicarbonate or both additives at these levels were subdivided and stored for three weeks at 3°C. or 47°C. prior to feeding. Egg collection from White Leghorn hens in individual cages were made after 12, 14, 16, 24, 26 and 28 days on test for carotenoid determinations.

Description of larvae and juveniles of Brycon falcatus (Characiformes: Bryconidae) from the Tapajós River sub-basin, Brazil [PDF]
Neotropical IchthyologyBrycon falcatus (Characiformes: Bryconidae) is an Amazonian fish species of great relevance in fisheries and as a seed disperser. However, knowledge about its early development is limited due to the lack of information for accurate identification.

Haemoglobin and size dependent constraints on swimbladder inflation in fish larvae [PDF]
, 2006 In developmental studies of fish species (especially physostomians) it could be demonstrated, that the lack of haemoglobin during larval and juvenile stages is a relatively common phenomenon. Generally it is linked with body translucency.

Deposition of carotenoids in egg yolk by short-term supplement of coloured carrot (Daucus carota) varieties as forage material for egg-laying hens [PDF]
, 2010 BACKGROUND: Supplying egg-laying hens with different forage materials may influence egg production and quality. The aim of this study was to examine the short-term effects of standard feed plus 70 g day−1 per hen of three coloured carrot varieties ...

Egg Yolk and Broiler Skin Pigmentation with Sweet Potato Vine Meal , ,
Poultry Science, 1974 Abstract Dehydrated sweet potato vine meal (SPVM) was evaluated as a xanthophyll pigment source for broiler skin and egg yolks. In the experiment with hens SPVM was compared with alfalfa meal in a diet in which these sources provided the only source of pigment.
