Genomic and transcriptomic analyses reveal the adaptation to semi-aquatic and aquatic life in spiders

  Genomic and transcriptomic analyses reveal the adaptation to semi-aquatic and aquatic life in spiders Abstract Spiders are largely terrestrial, but some lineages have independently adapted to marine and freshwater habitats. Although physiological and behavioral traits supporting these evolutionary transitions have been characterized, the genomic basis of adaptation to aquatic and semi-aquatic habitats in spiders remains unclear. Here, we report a chromosome-level genome assembly for the aquatic spider Argyroneta aquatica. Comparative analysis of 22 spider species supports two independent transitions in semi-aquatic (∼56 Mya) and aquatic (∼44 Mya) lineages. The aquatic spider show distinct respiratory morphology compared with terrestrial spiders, including anterior spiracles and denser tracheoles. Molecular evolution analyses identified lineage-specific shifts in selective constraint or evidence of positive selection linked to trachea development (e.g., Wnt-1, Catenin beta, TMEM23...

A proactive multidisciplinary approach to Naja atra envenomation reduces surgical burden and length of hospital stay

Abstract

We report that the implementation of a multidisciplinary team (MDT) protocol - integrating early ultrasound surveillance, prompt surgical intervention, targeted antimicrobial therapy, and optimized antivenom administration - was associated with a marked reduction the length of hospital stay and surgical burden among patients with Naja atra envenomation at a tertiary medical center in Taiwan. This approach shifts management from a reactive to a proactive strategy by enabling the early detection of tissue involvement and timely intervention.
