Wood charcoal analysis at the Sanctuary of Poseidon at Kalaureia, Poros aims to provide information on the vegetation of the area and its management and on the range of plants used in the activities taking place at the sanctuary. During the excavations of 2003–2005 in Areas D and C, systematic samples from fills and features from all the excavated strata were recovered and water flotation was used for the separation of wood charcoal from the sediment. Wood charcoal was found in two pits dated to the Early Iron Age, near the supposed altar of the Archaic period (Feature 05), in a deposit of the Hellenistic period (the “dining deposit”), in floor deposits (Early Iron Age and Late Classical/Early Hellenistic periods), and fills of different chrono-cultural periods (Archaic–Early Roman). All the taxa identified in the wood charcoal assemblages are thermophilous Mediterranean elements, most of them evergreen broad-leaved. The assemblages show that the most frequent taxon is the olive, followed by the prickly oak, the Fabaceae, and the heather. In most assemblages mock privet/buckthorn, strawberry tree, the pear and Prunus family species are present, while Aleppo pine, lentisc, the fig, and the carob trees are less frequent. Olive cultivation was an important economic activity during the whole life of the sanctuary and probably olive pruning constantly provided the sanctuary with fuel. The woodland would be the additional source of firewood for the sanctuary’s needs for fuel for mundane activities such as heating and cooking, for more formal ones, such as sacrifice, but also for industrial activities such as tile firing. Activities related to the reorganization of space and the expansion of the sanctuary may be reflected in charcoal of carpentry by-products as the fir, cypress, and maybe pine remains.

Paleoenvironmental Reconstructions

Abstract Paleoenvironmental reconstructions are commonly based on isotopic signatures of a variety of carbonate types, including rhizoliths and land-snail shells, present in paleosol-loess sequences. However, various carbonate types are formed through distinct biotic and abiotic processes over various periods, and therefore may record diverging environmental information in the same sedimentological layer. Here, we investigate the effects of carbonate type on δ13C, δ18O, and clumped isotope-derived paleotemperature [T(Δ47)] from the Quaternary Nussloch paleosol-loess sequence (Rhine Valley, SW Germany). δ13C, δ18O, and T(Δ47) values of co-occurring rhizoliths (-8.2‰ to -5.8‰, -6.1‰ to -5.9‰, 12–32°C, respectively), loess dolls (-7.0‰, -5.6‰, 23°C), land-snail shells (-8.1‰ to -3.2‰, -4.0‰ to -2.2‰, 12–38°C), earthworm biospheroliths (-11‰, -4.7‰, 8°C), and “bulk” carbonates (-1.9‰ to -0.5‰, -5.6‰ to -5.3‰, 78–120°C) from three sediment layers depend systematically on the carbonate type, admixture from geogenic carbonate, and the duration of formation periods. Based on these findings, we provide a comprehensive summary for the application of the three isotopic proxies of δ13C, δ18O, and Δ47 in biogenic and pedogenic carbonates present in the same sediment layer to reconstruct paleoenvironments (e.g., local vegetation, evaporative conditions, and temperature). We conclude that bulk carbonates in Nussloch loess should be excluded from paleoenvironmental reconstructions. Instead, pedogenic and biogenic carbonates should be used to provide context for interpreting the isotopic signature for detailed site- and time-specific paleoenvironmental information.

AbstractSpecies with small geographic ranges do not tend to have a high genetic structure, but some land snail species seem to be an exception. Xerocrassa montserratensis, an endangered land snail endemic to Catalonia (northeastern Iberian Peninsula), is an excellent model to study the processes affecting the phylogeography of specialized species of conservation concern. This species is restricted to xerophilous stony slopes and occurs within a small and fragmented area of ca. 500 km2. We sequenced the COI barcode region of 152 individuals from eight sites covering the entire range of the species. We found four genetic groups mostly coincident with their geographic distribution: a central ancestral group containing shared haplotypes among five localities and three groups restricted to a single locality each. Two of these derived groups were geographically and genetically isolated, while the third and most differentiated group was not geographically isolated. Geomorphologic and paleoclimatic processes during the Pleistocene can explain the divergence found between populations of this low dispersal species with historical fragmentation and secondary contacts. Nonetheless, recent passive large dispersal through streams was also detected in the central group. Overall, our study uncovered four evolutionary units, partially matching morphologically described subspecies, which should be considered in future conservation actions.
