The Transformation of Trace Metal Distributions Across the Mackenzie Shelf and Through the Northwest Passage

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Understanding the distributions of trace elements, like iron (Fe), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), cadmium (Cd), lead (Pb), barium (Ba), and vanadium (V) in the Arctic Ocean is motivated in part because they can modulate key biogeochemical rate processes as micronutrients and/or toxins for primary producers ...

Ultrasonographic features of the platypus abdomen via a limited left pre‐epipubic acoustic window from a series of 54 individuals

Australian Veterinary Journal, Volume 104, Issue 10, Page 653-660, October 2026.
Introduction There are notable differences between the platypus and common species of domestic mammal in the location and structure of some abdominal organs. The aim of this study was to detail the size, position and relative locations of organs in the left side of the platypus abdomen, to assist evidence‐based decision‐making in a clinical setting ...

Structural Variation in Whistle Patterns of Two Coastal Dolphin Species Co‐Occurring in the Southern Israeli Mediterranean Sea

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Two coastal dolphin species, the common bottlenose dolphin (Tursiops truncatus—Tt) and the short‐beaked common dolphin (Delphinus delphis—Dd), co‐occur along the southern Israeli Mediterranean coast, where the critically endangered Dd population faces ecological pressures, potentially including competitive exclusion by that of the Tt ...

Group‐Specific Variation in Heterodyne Frequencies of Biphonic Calls in Resident (R‐Type) Killer Whales Orcinus orca ater

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Biphonation—the simultaneous production of two independent fundamental frequencies within a single vocalization—is a prominent feature of killer whale calls, yet the factors influencing the presence and intensity of heterodyne frequencies, which arise from interactions between these fundamentals, remain poorly understood. We analyzed long‐term
