Article Reference Hunting, gathering, fishing and herding: animal exploitation in sandy Flanders (NW Belgium) during the second half of the 5th millennium BC
At Doel, in the lower basin of the river Scheldt, excavations have revealed camp sites of the Swifterbant culture dating back to the second half of the fifth millennium BC. They document the transition period from the Late Mesolithic to the Early Neolithic in Sandy Flanders (NW Belgium). The sites were situated on the top of sandy ridges which were covered with an alluvial hardwood forest vegetation and surrounded by wetlands. Only burnt animal remains survived at the sites, illustrating (seasonal) fishing and hunting. In addition, botanical evidence indicates the herding of domestic mammals. The finds are of importance for the reconstruction of the chronological development of the food economy of the Swifterbant culture.

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.
