The paper reports the first detection of Caenoplana decolorata in France using molecular analysis of a COI sequence from a 2014 specimen.

The paper generates and annotates the complete mitochondrial genome of Calliphora vicina, revealing phylogenetic divergence within the Calliphoridae family.

This study synthesizes the 20-year invasion history of the European green crab in the SW Atlantic, showing a northward expansion of ~1000 km and a slowing expansion rate, with predictions of future invasion hotspots.

This study compares setal morphology in Anolis lizards and geckos to show alternative structural strategies for achieving similar adhesive effectiveness.

This study establishes a method for cryopreserving Hydractinia symbiolongicarpus sperm to support genetic resource repositories, enabling long-term storage and future research.

This study hypothesizes that Fenton reaction-generated hydroxyl radicals during stormy weather induce spawning behavior in Ezo abalone.

This study refines the CANCRS pain scale for rabbits and evaluates its internal validity over time, showing it outperforms VAS in detecting pain variations.

The paper uses RAD-Seq SNP markers to reveal two genetically distinct populations of razor clam Sinonovacula constricta in Ariake Bay, Japan, with significant genetic differentiation.

This study investigates the phylogenetic position and evolutionary history of Haustoriidae amphipods using genetic data, finding they are basal gammarids and recommending taxonomic revisions.

The paper designates a neotype for Himantura uarnak based on genetic analysis and provides a phylogenetic classification of the species complex.

The paper identifies and classifies molecular forms of Anopheles subpictus s.l. and Anopheles sundaicus s.l. in the Indian subcontinent using DNA sequencing and phylogenetic analysis.

This study investigates winter activity and hibernation site selection of boreal bats using acoustic monitoring, finding increased activity near rock outcrops and root cellars, and a link between temperature and bat activity.

The paper shows that static analyses of skeletal levers cannot predict organism speed, demonstrating dynamic interactions between mechanical advantage and muscle physiology determine velocity.

The paper assesses the conservation status of 36 small mammal species in Alaska using the ASRS and compares it with NatureServe rankings, identifying data deficiencies and research priorities.

This study investigates symbiont acquisition and early development in deep-sea Bathymodiolus mussels, revealing that symbiont colonization begins during metamorphosis and shifts the mussels' nutritional strategy from filter-feeding to symbiont-dependent energy use.

The paper models the attack behavior of Gyrfalcons using proportional navigation guidance law with lower gain compared to Peregrines, promoting tail-chasing behavior.

The paper analyzes the phylogeography of four freshwater fish taxa in Japan and Korea, finding waves of migration from the Korean Peninsula replacing indigenous populations.

The paper reports the first detection of Hepatitis E virus in Australian rabbits through metatranscriptomic sequencing of liver samples.

The paper compares morphological differences in tadpoles of Corythomantis greeningi from Bahia and Piaui, Brazil, suggesting possible heterochrony or species distinction.

This study identifies CDF-1 and SUR-7 as regulators of lipid metabolism in C. elegans, linking zinc homeostasis to lipid accumulation via the SREBP-SCD pathway.
