Linking the Movement Behavior of the Laptev Sea Walrus to Sea Ice and Resource Dynamics

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The walrus subspecies inhabiting the Laptev Sea (Odobenus rosmarus divergens) remains one of the least studied walrus taxa and occurs in a region undergoing rapid environmental change driven by climate warming and increasing human activity. We conducted the first satellite telemetry study of walruses in this region, tracking 14 individuals ...

A DRACH Observed/Expected Metric Reveals the Evolutionary Landscape of Epitranscriptomic Regulation Across Bilateria

Annals of the New York Academy of Sciences, Volume 1564, Issue 1, October 2026.
Epitranscriptomic marks are highly variable across life stages and tissues, complicating comparisons between species. Using m6A consensus motifs, we developed a genomic indicator reflecting transcript methylability, the DRACH o/e score, that we used to investigate epitranscriptomic features and associated functions across nine bilaterian species.

Conchyliurus bhimilensis N. Sp. (Copepoda) from a Bivalve Mollusc Meretrix casta (Cherm) off Bhimnipatnam [PDF]

, 1976
Information on Copepod parasitic on marine organisms other than fishes is scanty. I was therefore of some interest to obsorve copepod of the genus Conchyliurus inhabiting the mantle cavity of a bivalve mollusk Meretrixi ...

The effects of bioturbation on porewater chemistry and early marine diagenesis: Evidence from a modern intertidal zone in Abu Dhabi, U.A.E.

Sedimentology, Volume 73, Issue 6, Page 2120-2142, October 2026.
ABSTRACT Early marine carbonate cements generally form in CaCO3‐supersaturated seawater at the seabed or shallow burial depths, resulting in syn‐sedimentary cemented firmgrounds and hardgrounds. The processes controlling early marine diagenesis are complex, particularly in coastal environments where geochemistry is influenced by different water sources

Cenozoic tropical carbonate platforms in the Santos Basin, SE Brazilian Margin

Sedimentology, Volume 73, Issue 6, Page 2454-2487, October 2026.
ABSTRACT Tropical carbonate platforms accompanied the latitudinal shifts of the tropical belt throughout the Cenozoic. Their flat‐topped geometries were influenced by a specific set of processes, including climate and sea‐level changes, carbonate facies, tectonics and continental runoff.

Depth-related mollusk abundance distribution in the northern Caspian Sea

The abundance of mollusk species has been studied in the northern Caspian Sea in 2013–2017. MacArthur's broken stick species-abundance model was applied. The mollusk abundance varied in regard to the sea depth.

Bivalve mollusk assemblages on São Paulo's northern continental shelf, southeast Brazil

Brazilian Journal of Biology
Soft bottom bivalve mollusc assemblages were sampled along a depth gradient (10 to 100 m) on the northern São Paulo shelf during the austral summer and winter. A one-way analysis of similarity permutation test revealed there was no seasonal difference in

Biochemical responses of bivalve mollusk unio tumidus in the vicinities of small and runoff hydropower plants.

, 2020
Hydropower is the most important and most economically advantageous branch from the renewal sources of the electro power. However, the environmental suitability of hydropower plants (HPPs) does not based on the biomarker approach.

Daily growth rates in shells of Arctica islandica: assessing sub-seasonal environmental controls on a long-lived bivalve mollusk

, 2005
Shells of the extremely long-lived bivalve mollusk Arctica is-landica (Linnaeus 1767) provide century-long, multi-proxy records of inter-annual environmental variability in mid-dle- to high-latitude marine settings.
