Seascape genomics reveals high genetic diversity and apparent panmixia in endemic Southern Ocean phytoplankton

Limnology and Oceanography Letters, Volume 11, Issue 6, November 2026.
Abstract The adaptive potential and resilience of cold‐adapted phytoplankton to climate change have the potential to impact polar marine food webs and global biogeochemical cycles. Two central but poorly constrained facets of adaptive potential in polar phytoplankton are standing genetic diversity and its spatial structure. Here, we partially sequenced

Relationships Between Oceanic Primary Production, Human Habitation and Variation in the Life‐History Traits of Coral Reef Fishes Across the Northern Line Islands

Fish and Fisheries, Volume 27, Issue 6, Page 1269-1282, November 2026.
ABSTRACT Biophysical processes associated with large‐scale nearshore oceanographic upwelling can influence coral reef communities by increasing the delivery of nutrient subsidies and food resources to reefs. However, these processes occur alongside anthropogenic activities that may alter ecological patterns across coral reef ecosystems.

Amazon River Plume Control on Carbonate Chemistry in the Western Tropical Atlantic

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract The Amazon River Plume (ARP) modulates the carbonate system of the western Tropical Atlantic (WTA) through physical and biological processes, including freshwater dilution, biological carbon uptake, and circulation‐driven transport; however, its basin‐scale impact has not been quantitatively assessed.

Acid-free countercurrent chromatographic separation of lanthanide nitrate salts using water / chloride ionic liquid biphasic systems

Journal of Ionic Liquids
The separation of lanthanide compounds typically relies on acidic media, complexing agents and multi-stage solvent extraction processes. Here we report an acid-free approach to lanthanide nitrate separation using liquid-liquid countercurrent ...

Influence of speed distribution in a rounded flow on the character of slopes erosion

RUDN Journal of Engineering Research, 2019
One of the most important issues of river hydraulics is the movement of water and the formation of a channel in a stream that has a non-straight-line outline in the plan. Under natural conditions for rivers characteristic winding shape in the plan.

Cool‐Water Dolphins Have Larger Appendages Than Warm‐Water Dolphins

Journal of Biogeography, Volume 53, Issue 10, October 2026.
ABSTRACT Aim Endothermic marine mammals face significant thermoregulatory challenges due to heat loss in the highly conductive marine environment. Allen's rule states that endothermic animals in cold environments have smaller appendages than those in warmer environments.

Sensitivity analysis of velocity field influence on condensers’ performance and parallel circuit design based on actual air velocity distribution

Case Studies in Thermal Engineering
Currently, most integral simulations of condensers are based on the assumption of uniform intake air, which differs from real scenarios and leads to imprecise circuit designs.

Are Deep‐Pelagic Fishes Truly Circumglobal? Evolutionary and Biogeographic History of Sternoptyx and Argyropelecus (Stomiiformes: Sternoptychidae) Reveals Extensive Cryptic Diversity

Journal of Biogeography, Volume 53, Issue 10, October 2026.
ABSTRACT Aim Deep‐pelagic fishes are often assumed to exhibit high connectivity and circumglobal distribution due to their usually large population sizes, pelagic lifestyle, and association with major oceanic current systems. However, recent molecular evidence challenges this paradigm, revealing geographically structured genetic diversity and cryptic ...

Selective recovery of lactic acid from carboxylic acid mixtures using N-octyl-2-pyrrolidone: COSMO-RS modeling and liquid–liquid distribution

Chemical Thermodynamics and Thermal Analysis
The equilibrium distribution of lactic acid (LA) between aqueous and organic phases is critical for its recovery from fermentation broths, which is hindered by structurally similar carboxylic acid impurities.
