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]
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.

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
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.

Modelling and analysis of FSO ground-to-train communications for straight and curved tracks [PDF]
In this work, a free space optical (FSO) link for the ground-to-train communications is proposed. Analytical analysis is carried out for the case of the straight as well as curved rail tracks.
