TLDR
In this paper, an analysis of coprolite specimens from the Lower Pecos canyonlands is presented as records of individual dietary decisions, and the resultant menus reflected in these clusters are evaluated with reference to a diet-breadth model for the known staple resources of the canyonlands.

The stable and radio-isotope chemistry of southeastern Utah Basketmaker II burials: dietary analysis using the linear mixing model SISUS, age and sex patterning, geolocation and temporal patterning

TL;DR: The Bayesian linear mixing model SISUS was used to reconstruct reliance on maize and intake of animal protein from the stable carbon (δ13C and nitrogen (ε15N) isotope values of 149 directly dated Basketmaker II burials as mentioned in this paper.

The what, how and why of archaeological coprolite analysis

TL;DR: A review of the history and current state of research in human coprolite analysis encompassing macroscopic, microscopic, and biomolecular approaches can be found in this article.

Phylogenomics in Cactaceae: A case study using the chollas sensu lato (Cylindropuntieae, Opuntioideae) reveals a common pattern out of the Chihuahuan and Sonoran deserts.

TL;DR: This study provides the first comprehensive plastome phylogeny for any clade within Cactaceae, and resolved the phylogeny of the chollas, including most interspecific and intraspecific relationships.

Environmental Productivity Indices for a Chihuahuan Desert Cam Plant, Agave Lechuguilla

Parks S. Nobel, +1 more
- 01 Feb 1986 - 
TL;DR: Water status proved to be the most important of the three variables considered, nearly all leaf unfolding occurring during the relatively wet summer and early fall, while seasonal variations in temperature had relatively small effects on net CO2 uptake over a 24—h period.

Geographic patterns in the reproductive ecology of Agave lechuguilla (Agavaceae) in the Chihuahuan desert. I. Floral characteristics, visitors, and fecundity.

TL;DR: The patterns of variation of flower morphology, color, and fecundity of Agave lechuguilla in 11 populations along a latitudinal gradient encompassing the whole range of the species in the Chihuahuan desert are described.

Inulin/oligofructose and anticancer therapy.

TL;DR: Dietary treatment with inulin or oligofructose incorporated in the basal diet for experimental animals reduced the incidence of mammary tumors induced in Sprague-Dawley rats by methylnitrosourea and inhibited the growth of transplantable malignant tumors in mice.
Frequently Asked Questions (8)
Q1. What is the main focus of coprolite studies?

While the recovery of macrofossils, pollen, and parasitological data has been the main focus of coprolite studies, recent research has also extended into areas of biochemical analysis including27DNA studies (Gilbert et al. 

Other possible techniques for characterizing chemical compounds include gas chromatography (GC), Fourier Transform Infrared Spectroscopy (FTIR), and gas chromatography- mass spectrometry (GC/MS), which also has the ability to monitor the isotope ratios of individual compounds (Degano and Colombini 2009; Evershed 1993; Gilbert et al. 

Prior to the advent of aDNA research, steroid analysis was themost commonly employed chemical technique in coprolite studies (Bull et al. 

While coprolites do provide enough carbon to be dated directly using traditional radiocarbon methods (Williams-Dean 1978), there is the potential of external contamination and admixture of components within the specimen. 

These models deal with a biological necessity, food acquisition that humans share with all other animals, perhaps another reason for the successful introduction of these models in anthropology. 

Despite having a relatively low caloric return by unit weight, prickly pear tunas have the highest caloric return rates of any resource considered in this model. 

Other microfossils have also been recovered from coprolite specimens, includingbacteria, fungal spores, diatoms, and phytoliths (Horrocks et al. 

Storage techniques such as drying and freezing, which are both traditionally used among potato cultivators in the Andes (Johns 1988, 1996), can significantly decrease starch granule digestibility (Dreher et al. 1984; Szymonska 2000).
