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 ambergris. Here, we extracted and analysed DNA sequences from jetsam ambergris from beaches in New Zealand and Sri Lanka, and sequences from ambergris of a sperm whale beached in The Netherlands. The lipid-rich composition of ambergris facilitated…

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

TLDR
A recently developed gas chromatography-mass spectrometry method is used, with suitable derivatisation of the hindered hydroxy group of ambrein, to screen a number of extracts of mammalian faeces for ambreIn formation in the terrestrial species is associated with coprolith formation.

Ambergris cololites of Pleistocene sperm whales from central Italy and description of the new ichnogenus and ichnospecies Ambergrisichnus alleronae

Ambergrisichnus alleronae igen. et isp. nov. from early Pleistocene clay marine deposits of Umbria, central Italy is here described, and attributed to cololites (evisceralites) of sperm whales. This

The age of ambergris

TLDR
Over forty jetsam samples were obtained, many collected on known dates, from mostly known beach locations across the globe, creating an inventory of verified jetsam ambergris, which is unprecedented.

Ambergris as an overlooked historical marine resource: its biology and role as a global economic commodity

TLDR
Being a product typically reported in whaling data and related to the economic exploitation of the sea, it is through the historical sources that its importance is clearly demonstrated.

Chromatographic and spectral studies of jetsam and archived ambergris

TLDR
Determination of the dichloromethane-soluble components of 12 samples of the natural product, ambergris, using capillary gas chromatography–mass spectrometry (GC–MS) revealed that the major component was ambrein, with co-occurring, variable proportions of steroids.

Cetacean mitochondrial DNA control region: sequences of all extant baleen whales and two sperm whale species.

TLDR
The findings suggest that the Antarctic minke whale should have a full species status, B. bonaerensis, and a close relationship between the gray whale (family Eschrichtiidae) sequence and those of the rorquals (family Balaenopteridae).

mapDamage2.0: fast approximate Bayesian estimates of ancient DNA damage parameters

TLDR
This work describes mapDamage 2.0, a user-friendly package that extends the original features of mapDamage by incorporating a statistical model of DNA damage, and provides estimates of four key features of aDNA molecules: the average length of overhangs, nick frequency, cytosine deamination rates in both double-stranded regions and overhangers, and base quality scores according to their probability of being damaged.

THE DIET OF GALÁPAGOS SPERM WHALES PHYSETER MACROCEPHALUS AS INDICATED BY FECAL SAMPLE ANALYSIS

TLDR
Analysis of lower beaks suggests that the sperm whales fed primarily on three genera of cephalopods; Histioteutbis (62%), Ancistrocbeirus (16%), and Octopoteut Bis (7%).

Whole-Genome Shotgun Sequencing of Mitochondria from Ancient Hair Shafts

TLDR
The observed levels of damage-derived sequencing errors were lower than those observed in previously published frozen bone samples, even though one of the specimens was >50,000 14C years old and another had been stored for 200 years at room temperature.

The origin of ambergris

TLDR
The biochemical processes which transform the coprolith into ambergris are consequential upon its incubation over a long period in the peculiar environment of the rectum teeming with bacteria.

Ambergris: The Search for Its Origin

A MBERGRIS is a rare wax-like pathological growth found in the stomach and intestines of the sperm whale (Physeter catodon). Its origin is still uncertain, but the condition may be due to the
