Functional Morphology of the Oral Jaws and Dentition Across Diverse Diets and Ontogeny in Prickleback Fishes (Stichaeidae)

open access: yesJournal of Morphology, Volume 287, Issue 5, May 2026.
Prickleback fishes (Stichaeidae) feed upon diverse diets, spanning carnivory (orange), omnivory (blue), and herbivory (green). We used microCT scanning to explore the functional morphology of the oral jaws and dentition across species and ontogeny. Focal species vary by morphotype and have divergent scaling patterns across diets.

Brain Morphology and Quantitative Assessment of Sensory Brain Areas in Southern Bluefin Tuna, Thunnus maccoyii (Scombridae, Teleostei)

open access: yesJournal of Comparative Neurology, Volume 534, Issue 4, April 2026.
The absolute and relative volume of major sensory and integrative brain regions of the southern bluefin tuna Thunnus maccoyii are examined using magnetic resonance imaging (MRI). A dominant cerebellum projects into the midbrain ventricular space, while the optic tectum represents a smaller proportion of total brain volume than previously estimated ...

The IceShark, an effective method for sampling plankton under sea ice

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 4, April 2026.
Abstract Seasonal sea ice plays a crucial role in shaping coastal ecosystem dynamics throughout the circumpolar region. Of particular interest to oceanographers is the ice‐ocean interface which functions as a multidimensional habitat, supporting both sympagic algae and pelagic phytoplankton in the under‐ice surface waters.

Adapting the growth‐form concept to geniculate coralline algae (Corallinales, Rhodophyta)

open access: yesJournal of Phycology, Volume 62, Issue 2, Page 512-532, April 2026.
Abstract Geniculate coralline algae (Corallinales, Rhodophyta) are a diverse group of calcifying macroalgae, loosely united by flexible upright axes formed by alternating calcified (intergenicula) and uncalcified segments (genicula), a trait that has independently arisen several times.
