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 ...

Diet variation and trophic impact of weakfish, Cynoscion regalis, within multiple marine habitats of the eastern United States

Journal of Fish Biology, Volume 105, Issue 6, Page 1628-1642, December 2024.
Abstract Weakfish (Cynoscion regalis) is not federally managed but feeds on species of management and ecological interest. We examined the trophic ecology of weakfish in Chesapeake Bay and the coastal and offshore waters of the eastern United States. For these areas, we determined the dominant prey of weakfish; identified how much diet variation was ...

Seasonal trends in Subantarctic plankton δ13C and δ15N are driven by phytoplankton dynamics and nutrient preference

Limnology and Oceanography, Volume 69, Issue 11, Page 2547-2563, November 2024.
Abstract The carbon and nitrogen isotope ratios (δ13C and δ15N) of marine plankton record biogeochemical processes at the base of the food web. In the Southern Ocean, such data, predominantly from summer, have been used to infer surface CO2 concentrations and the potential for biological carbon export.

Oceanographic mechanisms that possibly explain dominance of neritic-tropical zooplankton species assemblages around the Islas Marías Archipelago, Mexico

Latin American Journal of Aquatic Research, 2014
The nearshore zooplankton species assemblage, identified per taxonomic groups (20) and per species for 12 selected groups, was analyzed from samples collected during November 2010 at four volcanic islands of the Islas Marías Archipelago (IMA), located 90-

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 ...

Key to marine arthropod larvae [PDF]

Arthropods, 2012
The scope of this key is restricted to the larvae of marine arthropods. The key is based solely on their morphology, patterns of body segmentation, numbers of appendages, and mode of locomotion.

Euphausiacea diversity in a trans-oceanic transect through the South Atlantic Ocean: the first Atlantic record of Thysanopoda astylata Brinton, 1975

Anais da Academia Brasileira de Ciências, 2019
: Information about euphausiids in central South Atlantic Ocean is scarce; hence, we investigated species composition and distribution of euphausiids along a longitudinal transect in this region, with an emphasis on Thysanopoda.

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

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 ...
