Progressive Cellularization of Blastoderm and Extraembryonic Tissue Formation in the Ant Camponotus floridanus

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 5, Page 411-421, July 2026.
Illustration of the process of cellularization in Camponotus floridanus (top row) compared to Drosophila melanogaster (bottom row). Progressive direct formation of differentiating blastoderm mode is depicted using hexagons that represent energids (without borders) and cells (with borders). Colors of nuclei represent different cell types.

Polymorphism of the Gonadotropin‐Releasing Hormone Receptor Gene and Its Association With Production Traits in Isfahani Native Hens

open access: yesVeterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This research was conducted to identify genetic polymorphisms of the GNRHR gene on Isfahan native hen traits and their relationship with production traits. For this purpose, blood was taken, DNA was extracted, the target fragment was amplified and directly sequenced, and finally it was blasted with the reference gene in NCBI.

Yolk Pigmenters

open access: yes, 1972
Commercial quantities of deeply pigmented egg yolk are used by certain food manufacturers to give desirable yellow color to some of their products. Yellow com and alfalfa meal are the major natural sources of the yellow pigments (xanthophylls) found in ...

Multi‐Omics Profiling of the Scaphoideus titanus Yeast‐Like Symbiont Guides the Bioinformatic Discovery of Related Fungal Symbioses in Insects

open access: yesEnvironmental Microbiology, Volume 28, Issue 7, July 2026.
Genomic, proteomic and phylogenetic analyses of the obligate yeast‐like symbiont (YLS) associated with Scaphoideus titanus revealed retained metabolic flexibility and a monophyletic origin of insect‐associated YLSs within a free‐living fungal lineage. A novel computational pipeline was used to mine NCBI transcriptomic data and identified new candidate ...

The Feeding Ecology of Invasive Pink Salmon Juveniles in Northern Norwegian Rivers and Their Role as Prey to Native Salmonids

open access: yesEcology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Increasing numbers of invasive Pacific pink salmon (Oncorhynchus gorbuscha) are spawning in northern Norwegian rivers, leading to large numbers of juveniles migrating to coastal waters. This raises concerns about food competition with native salmonids in rivers, although details about the timing and intensity of pink salmon feeding and the ...

Multidisciplinary Evaluation of a 10‐Year Restoration Program for Two Endangered Atlantic Salmon (Salmo salar) Populations

open access: yesEvolutionary Applications, Volume 19, Issue 7, July 2026.
ABSTRACT Supportive breeding programs are widely implemented to counteract demographic collapse in threatened populations. Their long‐term success, however, depends on maintaining genetic diversity while ensuring that released individuals contribute effectively to wild populations.

Offspring Size Resolves a Population Growth Paradox in Rays and Skates

open access: yesFish and Fisheries, Volume 27, Issue 4, Page 927-941, July 2026.
ABSTRACT The maximum intrinsic population growth rate, rmax, is a key determinant of sustainable fishing limits and is increasingly used in risk assessments. We previously showed how the rmax of rays and skates (subclass Batoidea) scales with adult body size, temperature (and hence depth) such that smaller‐bodied species and those in warmer, shallower ...

Leveraging the Highly Data‐Rich Northeast Arctic Cod (Gadus morhua, Gadidae) to Identify Key Biophysical Factors Behind Recruitment Success

open access: yesFish and Fisheries, Volume 27, Issue 4, Page 1006-1027, July 2026.
The recent markedly reduced recruitment success (recruitment per spawner stock biomass) of Northeast Arctic cod (Gadus morhua, Gadidae) is seemingly largely attributed to the joint negative effect of increased temperature and cannibalism but also predation on the postlarvae by Northeast Atlantic mackerel (Scomber scombrus, Scombridae).

The Effect of Durian Fruit Waste Fermentated with Trichoderma Sp. in Laying Hen Ration on Egg Yolk Quality

open access: yes
Egg yolk has a high nutrient content, but cholesterol content and synthetic dyes added in egg yolk trigger concerns for the community so that alternatives are needed to improve egg quality by using Fermented Durian Fruit Waste (LBDF).
