Vitamin A and carotenoids in certain invertebrates. III. Euphausiacea [PDF]

Journal of the Marine Biological Association of the United Kingdom, 1955
Our published work has shown that the northern euphausiids, Meganyctiphanes norvegica, Thysanoessa raschii and T. inermis, contain much higher concentrations of vitamin A than we have found in any other marine Crustacea (Kon & Thompson, 1949a; Batham, Fisher, Henry, Kon & Thompson, 1951; Fisher, Kon & Thompson, 1952, 1953, 1954).

Insights into the diet and feeding behavior of immature polar cod (Boreogadus saida) from the under‐ice habitat of the central Arctic Ocean

Journal of Fish Biology, Volume 105, Issue 3, Page 907-930, September 2024.
Abstract Polar cod (Boreogadus saida) is an endemic key species of the Arctic Ocean ecosystem. The ecology of this forage fish is well studied in Arctic shelf habitats where a large part of its population lives. However, knowledge about its ecology in the central Arctic Ocean (CAO), including its use of the sea‐ice habitat, is hitherto very limited. To

Data_Sheet_1_The Vertical and Horizontal Distribution of Deep-Sea Crustaceans in the Order Euphausiacea in the Vicinity of the DeepWater Horizon Oil Spill.pdf

, 2020
The vertical and horizontal distributions of Euphausiacea in the northern Gulf of Mexico (GOM), including the location of the Deepwater Horizon oil spill, were analyzed from 340 trawl samples collected between April and June 2011. This study is the first

Ecotoxicological Assessment of Microplastics and Cellulose Particles in the Galápagos Islands and Galápagos Penguin Food Web

Environmental Toxicology and Chemistry, Volume 43, Issue 6, Page 1442-1457, June 2024.
Abstract Microplastic pollution threatens some of the world's most iconic locations for marine biodiversity, including the remote Galápagos Islands, Ecuador. Using the Galápagos penguin (Spheniscus mendiculus) as a sentinel species, the present study assessed microplastics and suspected anthropogenic cellulose concentrations in surface seawater and ...

, 1990
The Euphausiacea collected from 1,086 stations during the cruises 1-44 of FORV Sagar Sarnpada in the eastern Arabian Sea and the Bay of Bengal from 1985-'88 were studied for their spatial, seasonal and day and night abundance.

Studies on the Lipid of Euphausiacea, Euphausia superba. II

Journal of Japan Oil Chemists' Society, 1964
Properties of the phospholipids contained in Euphausia superba separated from stomach of fin whale in the Antarctic Ocean were studied from the view point of utilization of macro-plankton.Mixed fatty acids prepared from the phospholipids were identified with paper chromatography, as their 2, 4-dinitrophenylhydrazones for the saturated acids, and as ...

Biological and environmental covariates of juvenile sockeye salmon distribution and abundance in the southeastern Bering Sea, 2002–2018

Ecology and Evolution, Volume 14, Issue 4, April 2024.
This manuscript describes changes in the distribution and abundance of juvenile sockeye salmon from Bristol Bay, the world's largest run of sockeye salmon, in relation to spatio‐temporal and temporal changes in prey, competitors, and temperature. Spatio‐temporally varying densities of juvenile sockeye salmon varied with sea temperature, age‐0 pollock ...
