Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

open access: yesThe Anatomical Record, Volume 309, Issue 7, Page 1713-1748, July 2026.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

MRI Goes Mobile: Assessing the Reliability and Repeatability of a Mobile vs. Stationary 1.5 T MRI for Functional Neuroscience Studies

open access: yesNMR in Biomedicine, Volume 39, Issue 7, July 2026.
We present a technical feasibility study validating two mobile 1.5 T MRI scanners against a stationary system using a five‐subject test‐retest protocol (N = 50 datasets). Following relocation, hardware performance remained stable, with no systematic bias in B0 homogeneity or B1+ maps.

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

open access: yesFish and Fisheries, Volume 27, Issue 4, Page 781-812, July 2026.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

Stable Isotope Analysis (δ13C and δ15N) of Baleen Plates Reveals Feeding Patterns in Stranded Humpback Whales (Megaptera novaeangliae) Along the Brazilian Coast

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Humpback whales (Megaptera novaeangliae) from breeding stock A migrate annually between Antarctic feeding grounds (~65° S) and Brazilian breeding areas (~17° S). Traditionally considered to fast during migration, recent feeding observations and increased strandings along southeastern Brazil (~23° S) raise questions about possible shifts in ...

Total Numbers and Movements of Photo‐Identified Subantarctic (Type D) Killer Whales

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The distinctive Subantarctic (Type D) killer whale (DKW) (Orcinus orca) is a highly divergent and apparently inbred form previously known only from three mass strandings and several dozen at‐sea sightings, primarily from Patagonian toothfish (Dissostichus eleginoides) longline vessels in the southern Indian Ocean and from tourism vessels in ...

Baroclinic Submesoscale Eddies in the Ross Ice Shelf Cavity Alter Heat Pathways to the Ice Base

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The influence of baroclinic submesoscale eddies on basal melting beneath Ross Ice Shelf remains poorly understood. We analyzed a 4.5‐year mooring record from the central cavity and identified seven eddy‐like events from variability in density, velocity, and thermohaline structure, with horizontal scales (∼11 km) characteristic of submesoscale ...

Earthward Propagated Auroral Kilometric Radiation: Observations From Polar

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Auroral Kilometric Radiation (AKR), the strongest natural radio emission from Earth's magnetosphere, has been primarily observed in space. It is generally understood to propagate anti‐Earthward and be detected at large radial distances, while Earthward‐directed waves are thought to be blocked by the ionosphere. Surprisingly, AKR‐like emissions
