Euscorpius
Sampling in the Western Himalayas of India led to the discovery of a population of the genus Liocheles Sundevall, 1833, that differes from all Indian congeners. Molecular and morphological data confirmed the distinctiveness of the population, which is here described as a new species. The new species is morphologically similar to L. longimanus (Werner, 1939), from which it differs in the arrangement of trichobothria on external patella and structure of the hemispermatophore. A preliminary molecular phylogeny of the family Hormuridae based on the mitochondrial cytochrome oxidase I gene is presented.

New Locality Records And Future Habitat Suitability Of Sassanidotus Gracilis (Birula, 1900) (Scorpiones: Buthidae) In The Iran–Afghanistan–Pakistan Arid Belt, Ersen A. Yağmur, Kerim Çiçek, Homa Barati, Mohammad Moradi
Euscorpius
This study reports new locality records from Iran and a climate-based habitat suitability assessment for Sassanidotus gracilis (Birula, 1900) (Scorpiones: Buthidae) in the Iran–Afghanistan–Pakistan arid belt. We document new specimens from Sistan and Baluchestan Province, Iran, with an updated distribution map and illustrations, and we model the species' potential distribution across south-eastern Iran and adjacent parts of Afghanistan and Pakistan.
Habitat suitability was associated mainly with precipitation seasonality, precipitation of the wettest month, precipitation of the driest month, and slope. In an arid setting these rainfall variables are unlikely to indicate a need for moist habitat; they more plausibly track …

The Thai Journal of Veterinary Medicine
The endometrium undergoes extensive cyclical remodeling essential for reproductive success; however, the molecular mechanisms governing these processes in donkeys (Equus asinus) remain poorly characterized. To address this gap, we performed high-throughput RNA sequencing on endometrial tissues collected from Dezhou donkeys (n = 16) at four post-ovulation stages: Day 0 (ovulation), Day 3 (early luteal), Day 7 (mid-luteal), and Day 18 (late luteal/pre-luteolysis). Differential gene expression analysis, Gene Ontology enrichment, and KEGG pathway mapping were conducted to characterize temporal transcriptomic dynamics. We identified 2,474, 6,548, and 1,288 differentially expressed genes in Day 0 versus Day 3, Day 0 versus …

Snails In The Diet Of The Cutlip Minnow, Exoglossum Maxillingua, Tess A. Taloumis, Steven L. Powers
Southeastern Fishes Council Proceedings
The Cutlip Minnow, Exoglossum maxillingua, is an important stream fish native to the eastern United States. It has an unusual lower jaw morphology. Early hypotheses suggested the jaw morphology is an adaptation for feeding on snails. Despite the publication of numerous diet studies on this species, there is no documentation of snails as prey items. During recent snorkel observations in the Roanoke River, E. maxillingua was spotted carrying snails within their mouths, prompting further investigation. An in-depth temporal examination of the diet from 145 specimens of E. maxillingua across multiple sites was conducted to further investigate the diet of …

What Does Sentience Mean At The Neural Level?, Björn Brembs
What Does Sentience Mean At The Neural Level?, Björn Brembs
Animal Sentience
Jonathan Birch's (2025) LSE criteria for sentience include motivational trade-offs, exemplified by C. elegansweighing hunger against desiccation risk. Yet once the neural circuit is known, this "trade-off" reduces to a single inhibitory synapse—an ‘elemental’ account discrediting the ‘molar’ one. My commentary illustrates the same discrepancy in Drosophila: dopaminergic ramping during courtship as it progressively suppresses threat-detecting neurons; so persistence past danger reflects recalibrated valuation rather than a weighed decision. As neurobiology increasingly discovers such discrepancies, all criteria resting on behavioral classifications risk being defined away without altering the behavior's validity.

From Introduction To Biomass Dominance: The Invasive Fish Striped Piggy (Pomadasys Stridens) Reshaping Demersal Assemblages In The Eastern Mediterranean, Mehmet Cengi̇z Deval
Turkish Journal of Zoology
Rapid increases in the abundance and biomass of nonindigenous species have the potential to profoundly reshape demersal fish assemblages in the Eastern Mediterranean Sea, yet quantitative evidence from long-term standardized surveys remains scarce. In the present study, temporal changes in biomass dynamics and community structure were assessed using fishery-independent trawl surveys conducted on the continental shelf of Antalya Bay (GSA 24) during two periods a decade apart (2009–2010 and 2020–2021), with particular focus on the Lessepsian striped piggy Pomadasys stridens. Based on the second survey, in which both daytime and nocturnal sampling were conducted, the biomass index (BI) differed significantly …

This study investigated the effects of social media-driven live-streaming dietary supplementation on the gastrointestinal microbial community of captive Asian elephants (Elephas maximus) at the Elephant Kingdom, Surin Province, Thailand. A hierarchical two-tier observational design was used: Tier 1 compared a minimal-supplementation control group (Group H, n = 6) with a frequent heterogeneous-supplementation group (Group L, n = 18); Tier 2 compared, within Group L, low-frequency (Group A, ≤ 3 sessions per week, n = 7) and high-frequency (Group B, > 3 sessions per week, n = 11) live-streaming sub-groups. Faecal microbial profiles were obtained by 16S rRNA gene (V3–V4) …

Highly contagious viral pathogens—such as porcine reproductive and respiratory syndrome, classical swine fever, and African swine fever—continue to pose serious threats to the swine industry and cause major global economic losses. Conventional disease control approaches, such as vaccination and biosecurity, are limited by viral heterogeneity and immune escape mechanisms. Gene editing technologies, most notably the CRISPR/Cas9 system, offer an innovative means of introducing innate viral disease resistance or resilience in pigs. The continuous improvement of these tools can provide a sustainable strategy to enhance animal welfare and global food security and reduce reliance on traditional control measures. This review provides …

The wild animals that occupy large territories were found to adapt less easily to captive environments compared to those with small home ranges. Among big cats, captivity posed a range of challenges, with stress emerging as central factor influencing overall welfare. Transition into captive environment was shown to alter both behavior and physiological processes, largely due to changes in their natural habitat, environmental complexity and diet. Several health issues reported in big cats including alopecia, gastrointestinal issues, neuromuscular disorders such as hindquarter paralysis were associated with underlying metabolic dysregulation. Metabolic health was recognized as critical component of overall well-being, closely …
