Animal Genetics, Volume 57, Issue 2, April 2026.ABSTRACT This study aimed to identify and compare transmission ratio distortion (TRD) patterns using microsatellite (MS) markers and single nucleotide polymorphism (SNP) markers in a Hanwoo population from Gyeongnam Province. The objective was to construct parent‐offspring trios and investigate TRD patterns that may influence mortality and economic ...

Size Disparity in Putative Primate Adaptive Radiations and Other Mammalian Clades
American Journal of Biological Anthropology, Volume 189, Issue 4, April 2026.ABSTRACT Introduction Adaptive radiation is commonly viewed as the rapid production of phenotypic disparity and taxonomic diversity. Among primates, two clades have been identified as potential adaptive radiations: the lemurs of Madagascar and the platyrrhines of the Americas. This study examines these clades for one of the proposed signals of adaptive

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin
Biotechnology and Applied Biochemistry, Volume 73, Issue 2, Page 913-926, April 2026.ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Preserving DNAzyme Stability and Activity in Stool Samples for Clinical Diagnostics
Chemistry–Methods, Volume 6, Issue 4, April 2026.A RNA‐cleaving DNAzymes often lose activity in stool due to extensive nuclease‐mediated degradation. This work introduces a simple heparin‐based treatment that preserves DNAzyme integrity and catalytic function in this highly challenging matrix, enabling reliable pathogen‐responsive signaling in stool samples.

CNS Neuroscience &Therapeutics, Volume 32, Issue 4, April 2026.ANGPT2/Tie2 signaling upregulates LDHA and increases H3K18la, promoting the polarization of macrophages towards an M2 phenotype. Such M2 macrophages secrete high levels of proangiogenic factors, which facilitate endothelial cell proliferation and angiogenesis in the chronically ischaemic brain. ABSTRACT Aims This study aimed to investigate the specific

Potential Causes of Shedding Aggregations in Prairie Rattlesnakes
Ecology and Evolution, Volume 16, Issue 4, April 2026.The mechanisms that underpin aggregation behavior in animals—and the cues that elicit it—inform our understanding of how animals resolve tradeoffs among selection pressures. We documented aggregation during ecdysis in a population of asynchronously shedding prairie rattlesnakes (Crotalus viridis) and tested predictions generated from the four ...

Male Agonistic Behavior on Atlantic Cod Spawning Grounds
Ecology and Evolution, Volume 16, Issue 4, April 2026.The mating system of the Atlantic cod (Gadus morhua) has been described as a lek, a mating system where male–male aggressions are expected. However, observing aggressions directly in marine environments is challenging. Using accelerometer tags we show that male–male agonistic interactions, inferred from activity levels, are indeed present on natural ...
