A comprehensive embryonic staging series of the turtle Trachemys scripta

open access: yesDevelopmental Dynamics, Volume 255, Issue 3, Page 260-320, March 2026.
Abstract Background Turtles hold a unique place in vertebrate evolutionary history, making them critical assets in embryology research. Yet, they remain understudied as potential model organisms in the field. Here, to support experimental manipulations with turtle embryos, we have created a complete normal table of development for comprehensive ...

Genetic Sexing of the African Penguin, Spheniscus demersus Using Noninvasive Guano and Molted Feather Samples

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This study developed a noninvasive method for the DNA extraction and PCR‐based genetic sexing of S. demersus using guano and molted feather samples. Two primer sets (CHD1F/R & 2550F/2718R) were used that target sex‐specific length polymorphisms in the CHD1‐Z and CHD1‐W genes on the CHD1 sex chromosomes. Using methods optimized for the extraction of DNA

Viral tropism and detection of clade 2.3.4.4b H5N8 highly pathogenic avian influenza viruses in feathers of ducks and geese

open access: yesScientific Reports, 2021
Highly Pathogenic Avian Influenza viruses (HPAIVs) display a tissue pantropism, which implies a possible spread in feathers. HPAIV detection from feathers had been evaluated for H5N1 or H7N1 HPAIVs.

Detection of avian leukosis virus using polymerase chain reaction and enzyme linked immunosorbent assay [PDF]

open access: yes, 2004
The applications of polymerase chain reaction (PCR) and enzyme linked immunosorbent assay (ELISA) in detecting avian leukosis virus (ALV) subgroups A and J were studied in a flock of breeder chickens. Out of 74 chickens tested 9, 36, 13 and 16 were found

The Role of Dietary Vitamin E in Experimental Listeria monocytogenes Infections in Turkeys [PDF]

open access: yes, 2003
The current study was designed to determine if dietary vitamin E influenced either the gut clearance or levels of peripheral blood CD4+ and CD8+ T lymphocytes in adult turkeys experimentally infected with Listeria monocytogenes.

Evaluation of DNA Extracted from Timber Rattlesnake (Cotalus horridus) Cloacal and Blood Swabs for Microsatellite Genotyping

open access: yes, 2022
Genetic research is a key component to modern wildlife conservation, but it is contingent on the collection of reliable and high-quality genetic samples. Invasive genetic sampling techniques have potential to negatively impact individuals, which may be prohibitive when working with threatened and endangered species.

The evolutionary landscape and serotypic dynamics of avian infectious bronchitis virus from spike protein

open access: yesiMetaOmics, Volume 3, Issue 1, March 2026.
This study integrates two decades of surveillance with genomic and structural analyses to decipher how spike protein glycosylation haplotypes drive avian coronavirus evolution. We uncover how specific glycosylation patterns associate with receptor‐binding affinity, shape global transmission dynamics, and correlate with clinical outcomes.

Bridging the gap: improving methodologies for future avian microbiome research

open access: yesJournal of Avian Biology, Volume 2026, Issue 2, March 2026.
Recent advances in the field of wild avian microbiome research have significantly deepened our understanding of the eco‐evolutionary dynamics of bird–microbe interactions. Consequently, the field is now approaching a pivotal moment in uncovering the ultimate factors shaping avian microbiome structure, especially in relation to birds' ecological ...
