River‐Scale Evaluation of a Floating LED Light Array for Behavioral Guidance of American Eel

River Research and Applications, Volume 42, Issue 8, Page 1623-1637, October 2026.
ABSTRACT Exploiting the sensory physiology of migratory fishes to guide them away from hazards like hydroelectric turbines is of interest to regulatory agencies and hydropower operators to achieve conservation and management goals. Here we describe a river‐scale experiment where out‐migrating adult American eel (Anguilla rostrata) were tracked ...

Improving Micro– and Macro–Algae Speciation Mapping for Management: A Field‐Validated Sentinel‐2 and Sentinel‐3 Intercomparison in the Indian River Lagoon

GeoHealth, Volume 10, Issue 10, October 2026.
Abstract In recent years, the health of the Indian River Lagoon (IRL) on Florida's east coast has fluctuated due to recurring harmful algal blooms (HABs). These events typically involve cyanobacteria, dinoflagellates, or A. lagunensis (brown tide) causing water‐quality degradation and seagrass decline.

Microbial Respiration Across Subtropical Eddies: Submesoscale Variability and Biogeochemical Drivers

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Island‐induced eddies from the Canary Islands region propagate southwestward along the Canary Eddy Corridor, exporting biological and biogeochemical properties to the oligotrophic open ocean. However, their contribution to organic matter remineralization, and consequently to the biological carbon pump, throughout their life cycle remains ...

Optical Properties and Photochemical Transformation of the Dissolved Organic Matter Released by Sargassum

Frontiers in Marine Science, 2020
Chromophoric dissolved organic matter (CDOM) is the dominant absorber of ultraviolet radiation in the ocean, but its sources within the ocean, as well as its chemical composition, remain uncertain.

Contrasting population genetic structures of freshwater eels (Anguilla marmorata, A. bicolor, A. mossambica) from Madagascar

Journal of Fish Biology, Volume 109, Issue 4, Page 2409-2418, October 2026.
Abstract Freshwater eels (genus Anguilla) are of major biological and commercial interest due to their complex catadromous life cycle and as a high‐value fishery resource, but the biology of tropical species is still poorly understood. This study investigates the genetic integrity, diversity and population structure of three species of tropical eels ...

The edible brown alga Sargassum fusiforme (Fucales) at the southern distributional limit in mainland Japan has declined on coasts facing the open ocean, showing reduced size and density

Phycological Research, Volume 74, Issue 4, Page 343-354, October 2026.
SUMMARY The status of the edible brown alga Sargassum fusiforme (Fucales) in Kagoshima in 2025, located at the southern distributional limit in Kyushu, mainland Japan, was investigated to assess whether its populations were stable or declining, based on comparisons with herbarium specimens and records from previous studies conducted between the 1960s ...
