During the Bronze Age, the inhabitants of regions of Crete, mainland Greece, and Cyprus inscribed their languages using, among other scripts, a writing system called Linear A. These symbols, mainly characterized by combinations of lines, have, since their discovery, remained a mystery. Not only is the corpus very small, but it is challenging to link Minoan, the language behind Linear A, to any known language. Most decipherment attempts involve using the phonetic values of Linear B, a grammatological offspring of Linear A, to 'read' Linear A. However, this yields meaningless words. Recently, novel approaches to deciphering the script have emerged which involve a computational component. In this paper, two such approaches are combined to account for the biases involved in provisionally assigning Linear B phonetic values to Linear A and to shed more light on the possible connections of Linear A with other scripts and languages from the region. Additionally, the limitations inherent in such approaches are discussed. Firstly, a feature-based similarity measure is used to compare Linear A with the Carian Alphabet and the Cypriot Syllabary. A few Linear A symbols are matched with symbols from the Carian Alphabet and the Cypriot Syllabary. Finally, using the derived phonetic values, Linear A is compared with Ancient Egyptian, Luwian, Hittite, Proto-Celtic, and Uralic using a consonantal approach. Some possible word matches are identified from each language. [ABSTRACT FROM AUTHOR]

Several important habitats have become threatened in the last few centuries in the Mediterranean Basin due to major changes adopted in land‐use practices. The consequent loss of natural and seminatural orchid habitats leads to the appreciation of small anthropogenic habitats, such as cemeteries and roadside verges. Colonization of cemeteries and roadside verges by orchids has long been known, but no study to date compared the suitability of these two anthropogenic habitats for orchids. Therefore, in this paper our aim was to survey cemeteries and roadside verges and to compare these two habitats regarding their role in conserving Mediterranean terrestrial orchids. We conducted field surveys in three Mediterranean islands, Cyprus, Crete, and Lesbos, where both cemeteries and roadside verges were sampled on a geographically representative scale. We found a total of almost 7,000 orchid individuals, belonging to 77 species in the two anthropogenic habitat types. Roadside verges hosted significantly more individuals than cemeteries in Crete and Lesbos, and significantly more species across all three islands. Our results suggest that although cemeteries have a great potential conservation value in other parts of the world, intensive maintenance practices that characterized cemeteries in these three islands renders them unable to sustain valuable plant communities. On the other hand, roadside verges play a prominent role in the conservation of Mediterranean orchids in Cyprus and Greece. The pioneer status of roadside verges facilitates their fast colonization, while roads serve as ecological corridors in fragmented landscapes. [ABSTRACT FROM AUTHOR]

Large species that are isolated for thousands of years on islands often evolve extreme degrees of dwarfism. Very little is known about physiological processes that accompany such extreme transitions in extinct dwarf species. We tested whether physiological cycles of bone maintenance (remodelling) in dwarf adult hippopotamuses correlate with insularity-driven body mass shifts that may occur due to variables such as ecological release from predation pressure and change in access to resources. We hypothesised that hippopotamuses with the smallest body size should show higher values of osteocyte lacunae, proxies for osteoblast proliferation during cycles of remodelling, when compared to relatively larger dwarf forms, as well as much larger mainland common hippopotamuses. We examined 20 ribs from three extinct Pleistocene Hippopotamus species spanning a gradient in body size: H. minor (~132 kg, Cyprus), H. creutzburgi (~398 kg, Crete), and H. antiquus (~3200 kg, mainland Greece). Ribs were selected because they reflect bone metabolic rates that are not completely clouded by factors such as biomechanics. Densities of osteocyte lacunae (Ot.Dn) were examined in 864 individual secondary osteons observed in histology sections. We found the highest average Ot.Dn in the H. minor ribs, intermediate Ot.Dn in the H. creutzburgi ribs, and the lowest Ot.Dn in the H. antiquus ribs. It appears that Ot.Dn distinctly separated these three species, possibly signifying a gradient in bone remodelling such that bone tissue optimises maintenance in the face of insularity-driven reduction of body size. We discuss hippopotamus rib bone microstructure and the utility of Ot.Dn in palaeontological analyses for elucidating intricate biological processes occurring in bone of insular fossil mammals.
