Potential Impacts of Climate Interventions on Marine Ecosystems

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Rising global temperatures pose significant risks to marine ecosystems, biodiversity, and fisheries. Recent comprehensive assessments suggest that large‐scale mitigation efforts to limit warming are falling short, and all feasible future climate projections, including those that represent optimistic emissions reductions, exceed the Paris ...

A Revised Estimate of Calcium Carbonate Dissolution in Coastal and Shelf Sediments Suggests Large Shelf Exports in the Marine CaCO3 Cycle

Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract Calcium carbonate (CaCO3) dissolution plays a key role in the marine carbon and alkalinity cycles and the regulation of atmospheric CO2 levels across geological time scales. Until now, most attention has focused on dissolution in the deep sea, while dissolution in coastal and shelf environments remains poorly constrained.

The Metameric Echinoderm

Integrative Organismal Biology
Synopsis Animal phyla are distinguished by their body plans, the ways in which their bodies are organized. A distinction is made, for example, among phyla with bodies of many segments (metameric; e.g., annelids, arthropods, and chordates), others with completely unsegmented bodies (americ; e.g., flatworms and mollusks), and a few phyla ...

Marine Snow Dynamics in the NE Gulf of Mexico: Particle Abundance, Characteristics, and Impacts on Deepwater Horizon Oil Sedimentation

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract The Deepwater Horizon (DWH) oil spill in the NE Gulf of Mexico in 2010 was the largest accidental spill globally. During and after the spill, oil was incorporated into marine snow (marine‐oil‐snow or MOS) and sedimented to the seafloor, accounting for ∼21% of the oil released.

Actin-dependent cell elongation in teleost retinal rods: requirement for actin filament assembly. [PDF]

, 1981
Teleost retinal rods elongate when exposed to light. Elongation is mediated by a narrow necklike region called the myoid. In the cichlid Sarotherodon mossambicus, the rod inner segment (composed of the myoid with adjacent ellipsoid) increases in length ...

Characterization of the Nature of Organic Matter in Carbonate Rocks: Implications for Geological and Environmental Studies

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Organic matter in carbonate rocks plays a crucial role in processes such as fluid flow regulation, carbon sequestration, contaminant transport, and hydrocarbon recovery. This study employed multimodal spectroscopic techniques, including fluorescence imaging and Fourier transform infrared (FTIR) spectroscopy, to characterize the spatial ...

Half a century of echinoid population decline in the northern Gulf of Aqaba, Red Sea

Journal of Animal Ecology, Volume 95, Issue 3, Page 443-454, March 2026.
Multi‐decadal monitoring in the Gulf of Aqaba, northern Red Sea, reveals severe (>90%) declines of key echinoid grazers. These declines signify a collapse of crucial herbivory functions underpinning coral reef resilience. Results implicate accelerating anthropogenic stress as a principal driver, emphasizing the urgent need for sustained, species ...

Century‐Scale Changes in the Feeding Patterns of Demersal Fish Species in the Western North Sea

Fish and Fisheries, Volume 27, Issue 2, Page 99-115, March 2026.
ABSTRACT Understanding the extent and magnitude of change in marine food webs requires historical data that predates modern monitoring efforts. Such information can provide invaluable insights into the longer‐term impacts of altered trophic interactions, yet it is rarely incorporated into marine policy frameworks.
