Article Reference Sites with Holocene dung deposits in the Eastern Desert of Egypt: visited by herders?
The Tree Shelter and Sodmein Cave are two sites in the Egyptian Eastern Desert with stratified archaeological deposits. In Middle Holocene contexts of both sites, dated to the 7th millennium BP and later, animal dung has been found, in the shape of small concentrations of pellets at the Tree Shelter and of large accumulations at Sodmein Cave. The combination of several lines of evidence, including the size and weight of the excrements, the dimensions of the dung layers from Sodmein and the presence of hearths and artefacts inside them, and the species represented in the bone assemblages from Sodmein and the Tree Shelter, indicates that the dung was mostly deposited by herds of domestic ovicaprines. Sodmein Cave and the Tree Shelter belong to the oldest sites of the African continent where evidence for domestic small livestock has been attested. The importance and size of the herds seems to have been greater than would be suspected from the scant bone remains that were found. The visits to the caves were probably short but repeated over a long time period. Macrobotanical remains recovered from the dung suggest that these visits took place after seasonal winter rains.

Article Reference Stable isotope evidence for late medieval (14th-15th C) origins of the eastern Baltic cod (Gadus morhua) fishery
Although recent historical ecology studies have extended quantitative knowledge of eastern Baltic cod (Gadus morhua)exploitation back as far as the 16th century, the historical origin of the modern fishery remains obscure. Widespreadarchaeological evidence for cod consumption around the eastern Baltic littoral emerges around the 13th century, threecenturies before systematic documentation, but it is not clear whether this represents (1) development of a substantialeastern Baltic cod fishery, or (2) large-scale importation of preserved cod from elsewhere. To distinguish between thesehypotheses we use stable carbon and nitrogen isotope analysis to determine likely catch regions of 74 cod vertebrae andcleithra from 19 Baltic archaeological sites dated from the 8th to the 16th centuries.d13C and d15N signatures for six possiblecatch regions were established using a larger sample of archaeological cod cranial bones (n=249). The data stronglysupport the second hypothesis, revealing widespread importation of cod during the 13th to 14th centuries, most of itprobably from Arctic Norway. By the 15th century, however, eastern Baltic cod dominate within our sample, indicating thedevelopment of a substantial late medieval fishery. Potential human impact on cod stocks in the eastern Baltic must thus betaken into account for at least the last 600 years

Article Reference Palaeolithic dog skulls at the Gravettian Předmostí site, the Czech Republic
Whether or not the wolf was domesticated during the early Upper Palaeolithic remains a controversial issue. We carried out detailed analyses of the skull material from the Gravettian Předmostí site, Czech Republic, to investigate the issue. Three complete skulls from Předmostí were identified as Palaeolithic dogs, characterized by short skull lengths, short snouts, and wide palates and braincases relative to wolves. One complete skull could be assigned to the group of Pleistocene wolves. Three other skulls could not be assigned to a reference group; these might be remains from hybrids or captive wolves. Modifications by humans of the skull and canine remains from the large canids of Předmostí indicate a specific relationship between humans and large canids.

Article Reference Ecophysiology of dorsal versus ventral cuticle in flattened sawfly larvae.
Platycampus larvae are highly cryptic leaf feeders characterised by a dorso-ventrally flattened body, the dorsal integument resembling a shield. Dorsal and ventral cuticles from Platycampus luridiventris were compared by histology and gel electrophoresis. By Azan-staining, a red and a blue layer were distinguished in the dorsal cuticle, while the ventral cuticle showed one, almost uniform blue layer, as in both cuticles of control species. The two cuticles from P. luridiventris had similar amounts and sodium dodecyl sulphate-polyacrylamide gel electrophoresis profiles of soluble proteins, but not insoluble proteins. One insoluble protein (MW approximately 41 kDa) was visible as a large band in the ventral cuticle only. It is likely that this protein renders the cuticle elastic, and that the dorsal, red layer is the exocuticle, mainly composed of insoluble proteins. We discuss eco-physiological implications of the exocuticle in insects. Further, data from the literature indicate that the defence strategy in P. luridiventris larvae relies on being visually cryptic towards avian predators and tactically cryptic towards arthropod predators and parasitoids. Crypsis in both senses is favoured by the shield effect, itself based on an abnormally thick dorsal exocuticle. Although the larvae are external feeders, they may be considered as hidden from an ecological perspective.
