The first principal component plotted against the discriminant score obtained by using Roissy and Versailles as one of the groups in the discriminant analysis and Las Lomas as the other group. The individual specimens for the three sites are plotted, those from Las Lomas as grey circles, those from Roissy as black triangles and those from Versailles as black inverted triangles.

The relationship between the number of specimens found in a sample and the number of taxa represented by them is examined using data from 62 sites that were studied with the same recording and counting method. A critique is made of the various approaches that have been used to evaluate such data. The deficiencies of the "regression approach" and "s...

... bring out the shapedifference between the French and Iberian rabbits we therefore calculated a linear discriminant function based on the 2nd to 6th principal components, using the Roissy and Versailles samples as one group and the Las Lomas sample as the other group, since they were the geographically most extreme samples. The first principal component was then plotted against the discriminant score to give a graph in which the vertical axis represents size and the horizontal axis represents the shapedifference (Figure 4) Although the two groups are almost completely separated, the separation is based mainly on size. Nevertheless, there is a considerable difference in mean discriminant score between the two groups. ...

... Quando comparamos o número de taxa identificados com o tamanho da amostra, rapidamente concluímos que VNSP apresenta uma conjuntura única. Na figura 6, observa-se um gráfico que junta a análise realizada por Watson & Davis (2020), sobre a relação da diversidade taxonómica com o tamanho da amostra em sítios localizados em ilhas, com os dados de vários sítios portugueses do Calcolítico. ...
In this article, we present new data on the faunal remains recovered in the most recent excavations of the Chalcolithic settlement of Vila Nova de São Pedro. Building upon previous work, we analyze three additional contexts from area 1 and two from area 3, from test pits 1 and 2. The elements studied have allowed us to add more information to the characterization of the faunal assemblage accumulated by the people who inhabited Vila Nova de São Pedro. The high diversity of wild species identified in the assemblage, such as beaver, Iberian lynx, and bear, combined with the identification of various bones from aurochs, wild boar, and red deer, demonstrates the importance of hunting activity for these populations. The identification of domestic species such as cow, sheep, goat, and pig also confirms coexistence with a pastoral way of life, which would undoubtedly have been highly relevant for these populations.
... In doing so, he was working in parallel with his friend John Watson -the inventor of the 'diagnostic zone' approach in zooarchaeology (Watson 1979). John was a researcher with whom Simon had a natural affinity, which explains their long-standing research collaboration (e.g. Watson and Davis 2019;2020). While in Jerusalem, Simon also had his first teaching experiences. ...
