The 19Th Century

The results of a survey of vascular plants illustrated in the 19th-century publication Flora Graeca Sibthorpiana (FGS) and grown in Diomedes Botanic Garden (DBG) in Athens metropolitan area in Greece reveal a total number of 274 taxa belonging to 67 families, using the Raunkiaer system of categorising plants by life form (Raunkiaer, 1934). Therophytes dominate with 36 per cent, while hemicryptophytes, chamephytes and geophytes follow with 16 per cent, 14 per cent and 14 per cent respectively. In terms of life cycle, 60 per cent are perennials, 36 per cent annuals and 4 per cent other growth forms adapted to environmental disturbance. Although anthropogenic pressures and environmental stresses have caused loss of habitat and resulted in profound landscape transformation in the eastern Mediterranean, DBG contributes to the maintenance of approximately one-third of the plants collected in territories of the Levant in 1787. This living collection constitutes an important testimony to the scientific value, heritage and plant diversity described in FGS. Statistics are provided comparing the plants collected and illustrated for FGS and those now growing in DBG.

Functional Features

Since 2010, a bottom-up initiative has been launched in Santorini Island (Aegean Sea, Eastern Mediterranean) for the establishment of the first fully-protected marine protected area in the Cyclades, aiming at improving fisheries and enhancing responsible recreational uses at sea. Following discussions with local small-scale fishers and divers, two sites along the southern and southeastern coasts of the island were suggested as suitable to this end. In 2012, a baseline study was conducted at these areas to assess their state and provide an ecological snapshot that would enable sound designation and monitoring. Several ad hoc indices and metrics were applied, taking into account structural and functional features of the upper infralittoral algae and Posidonia oceanica beds. An integrated assessment of the infralittoral fish assemblages and their associated benthic communities was also performed. Our most important findings were: (i) the low total fish biomass and the absence of adult top predators, indicating overfishing; (ii) the overgrazing effects of the overabundant alien herbivore spinefoot fishes (Siganus spp.), as reflected by the abnormal structure of the algal communities; (iii) the scarcity of signs of pollution or other direct anthropogenic pressures, as indicated by the good environmental status of the P. oceanica meadows and the upper infralittoral vegetation; and (iv) the presence of a rich diversity of species and habitats, especially along the Akrotiri Peninsula and the wider volcanic Caldera. These findings provide useful insights on strengths and weaknesses of the study area and are discussed together with their implications for protection and management.

Household Processing

This article assembles examples of an unusual vessel found in domestic contexts of the Early Bronze Age around the Aegean and in the Eastern Mediterranean. Identified as a “barrel vessel” by the excavators of Troy, Lesbos (Thermi), Lemnos (Poliochni), and various sites in the Chalkidike, the shape finds its best parallels in containers identified as churns in the Chalcolithic Levant, and related vessels from the Eneolithic Balkans. Levantine parallels also exist in miniature form, as in the Aegean at Troy, Thermi, and Poliochni, and appear as part of votive figures in the Near East. My interpretation of their use and development will consider how they compare to similar shapes in the archaeological record, especially in Aegean prehistory, and what possible transregional relationships they may express along with their specific function as household processing vessels for dairy products during the third millennium BC.
