Evolutionary formation of melatonin and vitamin D in early life forms: insects take centre stage
Biological Reviews, Volume 99, Issue 5, Page 1772-1790, October 2024.ABSTRACT Melatonin, a product of tryptophan metabolism via serotonin, is a molecule with an indole backbone that is widely produced by bacteria, unicellular eukaryotic organisms, plants, fungi and all animal taxa. Aside from its role in the regulation of circadian rhythms, it has diverse biological actions including regulation of cytoprotective ...

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

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 ...

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 ...

Regional variation in the annual feeding cycle of juvenile walleye pollock (Theragra chalcogramma) in the western Gulf of Alaska [PDF]
, 2011 Juvenile fish in temperate coastal oceans exhibit an annual cycle of feeding, and within this cycle, poor wintertime feeding can reduce body growth, condition, and perhaps survival, especially in food-poor areas.

Predatory impact of the myctophid fish community on zooplankton in the Scotia Sea (Southern Ocean) [PDF]
, 2015 Myctophids are the most abundant mesopelagic fishes in the Southern Ocean, although their trophic role within the predominantly krill-based food web in regions south of the Antarctic Polar Front (APF) is poorly resolved. This study therefore examined the

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).
