The paper presents a 16-year study of Protocalliphora blowfly infestations and parasitoid interactions in Quebec farmlands, revealing spatial and temporal patterns and species composition shifts.

This study examines how the diameter and packing density of internal structures in artificial chimaera pectoral fins affect kinematic parameters like tip amplitude and undulatory wave propagation.

The paper examines how sex, body size, and mate location behavior influence eye structure and visual acuity in Centris pallida bees, finding sex and morphological differences in eye characteristics.

Third nuclear genome for arthropod pinworms (Thelastomatoidea): a PacBio long-read Cranifera cranifera assembly (242 Mb, N50 43 kb, 90.5-94% BUSCO) plus a 24644-base mitogenome and male redescription.

This study investigates the cold tolerance of Allocapnia pygmaea, finding it avoids freezing by surviving subzero temperatures and showing limited changes in cryoprotectants except for glycerol and myo-inositol.

Both experimental nestbox heating (+2.83°C) and cooling (-1.72°C) during early postnatal development significantly shorten day-13 relative telomere length in wild pied flycatcher nestlings without altering body mass.

The paper describes 115 new species of fungus gnats from Singapore using molecular and morphological data, highlighting the taxonomic challenges in species-rich clades.

This study improves Attractive Targeted Sugar Baits (ATSB) by incorporating blood feeding cues like bovine serum albumin and ATP, enhancing insecticide efficacy against sand flies.

This study investigates the survival of Tropilaelaps mercedesae on various matrices, finding it can survive over 144 hours on decomposing pupae and adults, suggesting transmission routes beyond brood.

The paper reports widespread hybridization between Syrian and Great-spotted woodpeckers across Europe, identifying hybrid forms and their distribution patterns.

IntegraTax is a tool that integrates DNA data with other evidence to determine species boundaries through clustering, visualization, and annotation.

This study examines the transcriptomic response of Saccostrea glomerata to Marteilia sydneyi infection, identifying differentially expressed genes involved in immune responses and potential resistance markers.

This study compares manual and automatic methods for identifying individual Yellowhammers through acoustic signals, finding that automated systems perform well up to 100 meters but face challenges beyond that.

This study shows that regeneration potential varies along the anterior-posterior axis in Capitella teleta, with posterior fragments regenerating more completely than anterior ones.

This study develops a combined diet-rearing protocol for Scepticus tigrinus that improves pupation success compared to artificial or plant-based diets alone.

This study uses ultraconserved elements to resolve the phylogenetic relationships within Peracarida, finding strong support for monophyly and specific clades.

This study shows lithium chloride is highly effective against Tropilaelaps mercedesae mites, with a lower LC50 than Varroa destructor, and confirms its efficacy in field conditions.

This study uses a 3D musculoskeletal model to analyze how hindlimb posture affects tendon stress and energy storage in hopping kangaroos, revealing posture-mediated elastic energy savings.

This study tests if a 40°C water bath kills Obama nungara egg capsules, finding it effective and supporting thermal quarantine measures.

The paper records and shares echolocation calls of bats in western Uganda to assess species richness using passive acoustic monitoring.
