This study shows nanopore metabarcoding can produce highly accurate, indel-free consensus barcodes for community analysis, comparable to Illumina sequencing.

The paper estimates the global number of earthworm species using the Joppa model, suggesting around 30,000 species with current descriptions representing only 20%.

This study finds that 8 hours of fasting under heat stress improves growth, meat quality, and gut health in broiler chickens compared to non-fasted heat-stressed birds.

The study tests pet birds in Hong Kong for Chlamydia psittaci and finds a low prevalence with genotype A strains linked to mainland China strains.

The paper challenges the power-limit paradigm in muscle energy output, proposing kinetic energy capacity as a new constraint and introducing the physiological similarity index.

The study documents annual sex change in Fimbriaphyllia ancora corals, with 70% of colonies switching sexes yearly, suggesting intrinsic factors like age or genetics drive this behavior.

The paper summarizes intraspecific size variation in four large odontocetes using literature and catch data, finding regional differences likely due to catch biases rather than population differences.

The paper analyzes the evolution of the palato-spheno-pterygoid complex in arvicoline rodents using 3D morphometric data from 90 specimens, identifying morphotype transformations and developing a protocol for genotype-phenotype studies.

This paper adds 101 new arthropod taxa to the inventory of Reunion Island, with Hymenoptera and Hemiptera being the most represented orders.

This paper identifies priority regions for conserving tetrapod evolutionary history by mapping threatened evolutionary history and defining 25 EDGE Zones globally.

The paper identifies planktonic drivers of gill disease and mortality in salmon aquaculture using molecular and morphological methods over a growing season.

The paper estimates 40,966 wild bird mortalities in eastern Canada due to H5N1 avian influenza in 2022, highlighting potential population-level impacts on Northern Gannets and American Common Eiders.

This study examines the daily vocalization patterns of Saipan Reed Warblers, finding they sing throughout daylight without dawn or evening choruses.

This study identifies microalgal biofilm as a settlement cue for Platynereis dumerilii larvae, showing species-specific preferences and enhancing juvenile growth.

The paper examines how body mass and climate interact to influence torpor energetics in Vespertilionidae bats, finding significant interactions affecting torpor traits.

This study evaluates the regeneration time, efficacy, and wash-resistance of PermaNet(R) Dual against susceptible and pyrethroid-resistant Anopheles gambiae strains, showing it meets WHO efficacy criteria and performs well against resistant strains.

This study identifies novel potential vectors of Brugian filariasis in Sri Lanka through field analysis of mosquito species carrying L3 larvae.

This study investigates the prevalence of kdr resistance in Culex quinquefasciatus against organochlorine insecticides globally, finding 63.1% resistance and varying mortality rates across insecticides.

This study investigates opsin-based photoreception in the crinoid Antedon bifida, revealing behavioural sensitivity to light, three rhabdomeric opsin genes, and potential extraocular photoreception structures.
