Louse‐induced mortality thresholds in Atlantic salmon of wild‐origin

Conservation Science and Practice
Wild salmonid fish are faced with the challenge of infections from the ectoparasitic salmon louse, which thus dictates the management of salmon aquaculture in areas where farms and wild populations co‐exist.

Argulus coregoni (Crustacea: Branchiura: Argulidae) Parasitic on a Dark Chub Nipponocypris temminckii (Cypriniformes: Xenocyprididae) in a Stream, Central Japan, with a List of Its Known Hosts in East Asia

Species Diversity
An adult male specimen of Argulus coregoni Thorell, 1864 was collected from the body surface of a dark chub Nipponocypris temminckii (Temminck and Schlegel, 1846) at 15 m elevation in a small stream in central Japan.

Sound‐Based Assembly of Magnetically Actuated Soft Robots Toward Enhanced Release of Extracellular Vesicles

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Magnetic soft robots offer promise in biomedicine due to their wireless actuation and rapid response, but current fabrication methods are complex and have limited cellular compatibility. A new, contactless bioassembly strategy using hydrodynamic instabilities is introduced, enabling customizable, centimeter‐scale robots.

Occurrence and Morphology of Argulus coregoni (Crustacea: Branchiura: Argulidae) on Three Species of Fishes in Three Orders (Acipenseriformes, Cypriniformes, and Salmoniformes) Reared at a Fish Hatchery in Central Japan

Species Diversity
Adults of both sexes of Argulus coregoni Thorell, 1864 were collected from the body surface of bester [a hybrid of beluga Huso huso (Linnaeus, 1758) × sterlet sturgeon H. ruthenus (Linnaeus, 1758)], common carp Cyprinus carpio Linnaeus, 1758, and rainbow

T. rex cognition was T. rex‐like—A critical outlook on diverging views of the neurocognitive evolution in dinosaurs

The Anatomical Record, EarlyView.
Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

The Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

The Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

Optimization of calcium oxide treatment against salmon louse (Lepeophtheirus salmonis). A controlled laboratory study

Aquaculture Reports
Salmon louse (Lepeophtheirus salmonis) infestations pose a significant challenge to the salmonid farming industry. While most conventional water-treatment protocols primarily target lice at parasitic stages once attached to the fish, preventive measures ...
