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.

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 ...
