The paper describes a new salamander species, Pachytriton, from Anhui, China, based on morphological and molecular analyses.

This paper develops a sandwich ELISA to detect A1 beta-casein in A2 milk, showing it can identify contamination at 1% A1 spike in a herd of A2A2 cows.

The paper applies KBA Criterion E across Europe to assess its effectiveness in identifying irreplaceable sites for insects and tetrapods, highlighting sensitivity to analytical choices and proposing adjustments for broader applicability.

Integrating 1,794 records from museum collections, literature, GBIF, and iNaturalist with COI DNA barcoding establishes a checklist of 15 Bombus species and their floral interaction networks across continental Ecuador.

This study adds Bhutanese red panda mitochondrial sequences to a global dataset, showing they form a single species with a genetic cline across their range, not distinct subspecies.

This study shows that molybdenum supplementation reduced honey bee winter mortality by 44% on average and up to 75% in some locations, with no adverse effects on bee health or honey composition.

The paper describes a novel histopathological finding of midgut smooth muscle necrosis (MSMN) in whiteleg shrimp postlarvae associated with TPD/GPD, highlighting its distinct features and potential diagnostic significance.

This study identifies eight sand fly species, including four new to science, in Singapore using morphological analysis and DNA barcoding, highlighting the need for biosurveillance due to the risk of leishmaniasis introduction.

This study measures corticosterone levels in budgerigars to assess stress from human presence, restraint, and social stress transmission, finding that repeated handling and restraint cause significant stress, while social stress transmission is limited.

The paper presents a geo-referenced dataset of Aedes mosquito occurrences in Kinshasa, DRC, collected using multiple trapping methods, to support arbovirus vector control strategies.

The paper reclassifies the Sundarbans Crow butterfly as a subspecies of E. core, challenging its previous status as a distinct species and highlighting the need for integrative systematics in conservation.

This study evaluates the insecticidal effects of n-hexane fractions from Zingiber officinale and Moringa oleifera oils on Callosobruchus chinensis, finding M. oleifera more effective.

This study finds that mass-planted large bromeliads in urban areas increase mosquito populations, raising public health risks.

This study shows that including a tick box on online classified ads improves reporting of CITES Certificate ownership compared to free text fields.

This study shows lipid nanoparticles (LNPs) enhance lipid metabolism and suppress reproduction in cnidarians, suggesting their potential for coral aquaculture.

This study uses climate and genetic data to show that climate change shaped leopard population dynamics, leading to extinction in Europe and structuring populations in Asia and Africa.

The paper assembles a gap-free telomere-to-telomere pig genome, revealing new genes, structural variations, and insights into centromere evolution and breed-specific selection.

This study compares body shapes and histology across goldfish strains to show that similar globular shapes arise through different developmental pathways.

This study investigates the genetic structure of the steppe marmot using mitochondrial markers and identifies two phylogroups that challenge the existing subspecies classification.

This study investigates X-ray irradiation of Aedes aegypti eggs to sterilize wild-type and Wolbachia-infected mosquitoes, finding lower irradiation doses needed for Wolbachia-infected eggs.
