Galgenbühel/Dos della Forca: un nouveau site sauveterrien dans la vallée de l'Adige (Bozen/Bolzano, Italie)

by Ursula Wierer

Co-authored with M. Bazzanella and L. Betti

The mesolithic site of Galgenbühel/Dos de la Forca lies in the Adige Valley near Salurn/Salorno in the Autonomous... more The mesolithic site of Galgenbühel/Dos de la Forca lies in the Adige Valley near Salurn/Salorno in the Autonomous Province of Bozen/Bolzano. The rockshelter is situated upon a cone not far from the present flow of the Adige river, at an altitude of 225 m a.s.l.. Since the beginning of the excavations in 1999 various anthropic levels have been discovered, all of them ascribed to the ancient Mesolithic. Charcoal from the upper levels submitted to AMS-radiocarbon dating achieved ages of 8.190±65 BP (7.326-7.032 BC cal.) and 8.560±65 BP (7.705-7.478 BC cal.).
Among the archaeological features we mention some fireplaces, seldom structured, and a probable posthole. The archaeological record is made up of flint industry including the characteristic sauveterrian armatures, bone industry, perforated shells of Columbella rustica, faunal remains of large mammals (red deer, wild boar, beaver) as well as small mammals. The huge amount of well preserved fish remains (above all luce), together with molluscs and tortoises, marks an economy based mainly on fishing.

Abstract:
Many perennial plants are often huge biomass producers capable of capturing the solar energy and producing valuable nutrients, plants that represent food source for many herbivores. Some plants have toxic properties to some animal species whereas to others they represent a priority in herbivore’s diet. We investigated the influence of Armoracia rusticana and Symphytum officinale upon the development of one of the most farmed and consumed terrestrial snails Helix aspersa Muller (Cornu aspersum), an excellent animal protein source for humans. The experiments took place in town of Băişoara, Cluj County, Romania in the June – August 2010 interval. The adult Helix aspersa Muller snail populations in the witness lots display a survival mean rate under extreme heat wave and drought conditions of just 6.50 ± 1.29 while the population in the experimental lots with Armoracia rusticana and Symphytum officinale presented higher survival mean rate of 14.00 ±0.82 and 16.75 ±1.50 respectively. As far as prolificacy, the witness enclosure batches accounted for 100 ±5.72 while the batches in experimental enclosures accounted for 248.00 ±8.29 and 140.00 ±5.10 respectively. We included the fitness component test, as an indicative of snail’s vitality and energetic condition, measuring their crawling mean speed and the mean heart bit rate of new born baby snails that have similar body weights. While the heart bit rate differences between the different batches were not significant, the mean speed presented significant differences directing us to the conclusion that plants such as Armoracia rusticana and Symphytum officinale not only represent valuable nutritive foods to Helix aspersa Muller adults and youngsters but also have protective values against stress conditions such as severe drought and prolonged heat waves. Such plants can represent an additional assurance for an efficient and ecological snail farming technology as an important source of quality animal protein for human consumption, capable to deliver a high quantity of animal protein from a given land surface, representing a venue towards sustainable agro-economical development.
