Blood from a stone: Do the trace metals of sperm whale coproliths reveal a contribution from squid haemolymph?

Autor: Steven J. Rowland, Robert Clough, Paul A. Sutton, George H. Rowland

Publikováno v: Journal of Trace Elements and Minerals, Vol 9, Iss , Pp 100156- (2024)

Background: Ambergris is a coprolith produced by some sperm whales (∼1 %). It has been hypothesised that the metals in ambergris derive from the haemolymph of squid in the whale diet (mainly copper). However, few data exist.We report analysis of 10

Fish Fingerprinting: Identifying Crude Oil Pollutants using Bicyclic Sesquiterpanes (Bicyclanes) in the Tissues of Exposed Fish

Autor: Francis D. Spilsbury, Alan G. Scarlett, Steven J. Rowland, Robert K. Nelson, Gemma Spaak, Kliti Grice, Marthe Monique Gagnon

Publikováno v: Environmental toxicology and chemistryREFERENCES. 42(1)

In the present study, we investigated the possibility of identifying the source oils of exposed fish using ratios of bicyclic sesquiterpane (bicyclane) chemical biomarkers. In the event of an oil spill, identification of source oil(s) for assessment,

First evidence of terrestrial ambrein formation in human adipocere

Scientific Reports

To date, the only known occurrence of ambrein, an important perfumery organic molecule, is in coproliths found in about one in a hundred sperm whales. Jetsam ambergris coproliths from the whale are also found occasionally on beaches worldwide. Here w

Biosynthesis of ambrein in ambergris: evidence from isotopic data and identification of possible intermediates

Autor: Paul A. Sutton, Steven J. Rowland, George A. Wolff

Publikováno v: Natural product research

Ambrein is found in ambergris, a coprolith occurring in the rectum of the sperm whale. In vitro, ambrein is produced by enzymatic cyclisation of squalene, via a monocyclic intermediate. However, little is known of the in vivo process. In order to fin

Volatile and semi-volatile components of jetsam ambergris

Autor: Michael Wilde, William J. Robson, Paul A. Sutton, Steven J. Rowland

Publikováno v: Natural Product Research. 34:3048-3053

Volatile and semi-volatile compounds account for the odors, long valued in the perfumery industry, of the natural product, ambergris. Here we demonstrate application of solid phase micro extraction (SPME) and gas chromatography-mass spectrometry (GC-

Synthesis of 14C-labelled polystyrene nanoplastics for environmental studies

Autor: Maya Al-Sid-Cheikh, Richard C. Thompson, Marc-André Cormier, Steven J. Rowland, Ralf Kaegi, Theodore B. Henry

Publikováno v: Communications Materials. 1

Available analytical methods cannot detect nanoplastics at environmentally realistic concentrations in complex matrices such as biological tissues. Here, we describe a one-step polymerization method, allowing direct radiolabeling of a sulfonate end-c

Ambrein: a minor, but common constituent of mammalian faeces?

Autor: John K. Volkman, Simon N. Ingram, Diane Claridge, Steven J. Rowland, Christopher H. Vane, Charlotte Dunn, Paul A. Sutton, Barbara von der Lühe

Publikováno v: Natural product research. 35(22)

For nearly 200 years, the only natural source of the alcohol ambrein has been coproliths produced in about 1% of sperm whales and in related jetsam. However, the finding of ambrein in adipocere/faeces of human corpses, led us to hypothesise that ambr

Jetsam ambergris, found on beaches worldwide, has always been assumed to originate as a natural product of sperm whales (Physeteroidea). However, only indirect evidence has ever been produced for this, such as the presence of whale prey remains in am

The age of ambergris

Ambergris, which is a coprolith originating from the sperm whale, has been found only rarely, but for centuries, as jetsam on beaches all over the world. There are no reliable data indicating how long such samples may have remained at sea, with unsub
