Examines the age of occurrence of enamel hypoplasia in a representative sample population of middle 19th century in Florence, Italy. Weaning habits of 19th century Italians; Enamel defects as stress indicators; Gradual introduction of dietary supplements.

As a means for investigating human mobility during late the Neolithic to the Copper Age in central and southern Italy, this study presents a novel dataset of enamel oxygen and carbon isotope values (δ18Oca and δ13Cca) from the carbonate fraction of biogenic apatite for one hundred and twenty-six individual teeth coming from two Neolithic and eight Copper Age communities. The measured δ18Oca values suggest a significant role of local sources in the water inputs to the body water, whereas δ13Cca values indicate food resources, principally based on C3 plants. Both δ13Cca and δ18Oca ranges vary substantially when samples are broken down into local populations. Statistically defined thresholds, accounting for intra-site variability, allow the identification of only a few outliers in the eight Copper Age communities, suggesting that sedentary lifestyle rather than extensive mobility characterized the investigated populations. This seems to be also typical of the two studied Neolithic communities. Overall, this research shows that the investigated periods in peninsular Italy differed in mobility pattern from the following Bronze Age communities from more northern areas. [ABSTRACT FROM AUTHOR]

The paper aims to point out the subsistence in Eneolithic Central Italian communities by Stable Isotope Analysis. This period marked a tipping point in the food strategies because it was characterized by economic changes and several technological improvements leading to enhance land exploitation and livestock breeding. Carbon and nitrogen stable isotope analysis has been used to analyze the food consumption of 54 people belonging to 5 Eneolithic communities scattered throughout Central Italy, where no data have yet been published. The estimation of the main protein intake has been achieved in order to quantify the differences among these communities. The results are consistent with a diet mainly based on terrestrial resources, with no exclusive marine sources consumption, although their occasional usage cannot be ruled out, especially for selected funerary contexts. The data suggest an overall subsistence based on greater local resource procurement, supported by regional productivity maximization. A roughly homogeneous landscape could be outlined in Tuscany and Marche communities witnessing a shared diet preference that could be modified by local preferences. The fully developed trade routes between the two sides of the Apennines could address the overall dietary homogeneity of the studied communities, especially between Fontenoce di Recanati and the southern Tuscan human groups such as Grotta del Fontino and Buca di Spaccasasso, with lesser influence for Le Lellere and Podere Cucule that seem to suggest a more locally based subsistence, even though the funerary affinities do not match this overall diet homogeneity.

Over the last few years, genomic studies on Yersinia pestis, the causative agent of all known plague epidemics, have considerably increased in numbers, spanning a period of about 5,000 y. Nonetheless, questions concerning historical reservoirs and routes of transmission remain open. Here, we present and describe five genomes from the second half of the 14th century and reconstruct the evolutionary history of Y. pestis by reanalyzing previously published genomes and by building a comprehensive phylogeny focused on strains attributed to the Second Plague Pandemic (14th to 18th century). Corroborated by historical and ecological evidence, the presented phylogeny, which includes our Y. pestis genomes, could support the hypothesis of an entry of plague into Western European ports through distinct waves of introduction during the Medieval Period, possibly by means of fur trade routes, as well as the recirculation of plague within the human population via trade routes and human movement.

ABSTRACT Stable isotope analysis in the reconstruction of human palaeodiets can yield clues to early human subsistence strategies, origins and history of farming and pastoralist societies, and intra- and intergroup social differentiation. In the last 10 years, the method has been extended to the pathological investigation. Stable isotope analysis to better understand a diet-related disease: celiac disease in ancient human bones was carried out. To do this, we analyzed the nitrogen and carbon isotopic composition of human ( n = 37) and faunal ( n = 8) bone remains from the archaeological site of Cosa at Ansedonia, on the Tyrrhenian coast near Orbetello (Tuscany), including the skeletal remains of a young woman (late 1st century-early 2nd century Common Era [CE]) with morphological and genetic features suggestive of celiac disease. We compared the young woman's isotopic data with those of other individuals recovered at the same site but from two later time periods (6th century CE; 11-12th century CE) and with literature data from other Italian archaeological sites dating to the same period. Her collagen δ13C and δ15N values differed from those of the samples at the same site, and from most but not all of the contemporary sites. Although the woman's diet appears distinct, chronic malnutrition resulting from severe malabsorption of essential nutrients due to celiac disease may have affected the isotopic composition of her bone collagen.

The Monti 'e Prama site, made famous by the discovery of numerous large stone statues "The Monti 'e Prama giants", is a necropolis located in Sardinia, dated to the X - IX BC. The statues, all depicting men: archers, boxers and fencers, were found collapsed and fragmented, in the immediate vicinity of the burials. The sample of inhumated skeletons consists of 41 individuals, almost all males, who died when adolescents, young adults or, more rarely, mature. Neither children nor elders were present. An interesting question is whether the statues depicted the deceased or could have come from a temple located elsewhere. In this regard, the diagnosis of the age at death is an element of considerable importance, but the skeletal age is difficult to determine in this sample because of the bad state of preservation of the bones, while the teeth are well preserved and have allowed us to reconstruct a seriation in order to seniority on the basis of wear. Since tooth wear is a weak indicator of age, we also used a method based on the deposition of secondary dentine, by the pulp area/tooth area ratio calculation, which gets a greater precision. It was found that the correlation between the degree of wear and pulp area/tooth area ratio is somewhat low, indicating that the two processes, although both age-dependent, do not have a very similar trend. It was also noted that the method of pulp area / tooth area ratio tends to "make the individuals grow old" in cases of discrepancy, but in general confirms the young age of many adults and the absence of the elderly. In this sense, it confirms even the possibility of an association between the deceased and the statues of young athletes or warriors. The results of pulp area/tooth area ratio method, by moving the sample as a whole to ages slightly more advanced than those suggested by wear, offers the hypothesis that the community was characterized by alimentary habits involving a little wearing mastication activity.
