Growth Autocorrelation in Atlantic Bluefin Tuna Thunnus thynnus Larvae in the Northwest Mediterranean and the Gulf of Mexico

open access: yesFisheries Oceanography, Volume 35, Issue 2, Page 297-305, March 2026.
ABSTRACT Growth and survival rates during the early life stages are key vital parameters driving population dynamics of fish. Growth rates generally present a pattern of autocorrelation. Growth autocorrelation is stronger when faster and slower growing individuals continue to grow faster and slower.

Optical contamination screening of materials with a high-finesse Fabry-Perot cavity resonated continuously at 1.06-µm wavelength in vacuum [PDF]

open access: yes, 1999
An optical-loss measurement system based on a resonant Fabry Perot cavity at 1.06µm in vacuum has been developed for independent monitoring of the cavity total loss and the optical absorption loss.

Characterization of salmon‐foraging harbor seals (Phoca vitulina) in the Erimo region, Hokkaido, Japan, using finite mixture models

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
Finite mixture models revealed that older, larger harbor seals specialize in salmon predation at setnets in Hokkaido, Japan, suggesting targeted management strategies focusing on these specialist individuals could effectively reduce fishery conflicts while protecting the broader seal population.

Dissolved and Particulate Methylated Mercury in a Highly Productive Area of the Southern Ocean

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 1, January 2026.
Abstract Methylated mercury (MeHg), including dimethylmercury and monomethylmercury (MMHg), is a pollutant of concern because it biomagnifies in marine biota. The formation of MeHg in the oceans, specifically at highly productive regions and at high oxygen levels, remains elusive.
