Article Reference Bird bones from Trou de Chaleux and the human exploitation of birds during the late Magdalenian in Belgium
The Trou de Chaleux is a cave site located in Belgium. It delivered a rich late Magdalenian material culture constituted mainly of lithic artefacts but also including bone industries and figurative art. This paper presents the results of the analysis of the large collection of bird remains recovered by E. Dupont in 1865, which was yet unstudied from taphonomical and archaeozoological perspectives. In addition to the taxonomic identification, surface alterations were investigated based on a macro- and microscopic analysis, including an analysis of wear traces and elementary composition. Special attention is devoted to the presence of human modifications such as disarticulation or butchering marks, traces of heating, presence of colourants and traces of bone working. The taphonomic history of the bird assemblage is reconstructed and the use of birds by humans characterized, as well as their importance in past human activities. We also discuss evidence for seasonal exploitation and for reconstructing the local environment and integrate our results with evidence from other Magdalenian assemblages from north-western Europe. At Trou de Chaleux, birds were used for food, as raw material for bone working and for symbolic purposes. The exploitation of avian products was intense, and species have been used for several purposes such as the raven and snowy owl having been exploited both for food and for symbolic reasons. Large bird bones were used as raw material to produce artefacts, but the use-wear analysis did not evidence unambiguous traces related to the use of the objects produced. Despite several limiting factors, the bird material from Trou de Chaleux considerably increases the knowledge of past human exploitation of birds during the late Magdalenian in north-western Europe.

Article Reference Black adzes in the Early Neolithic of Belgium. Contribution of the Raman microspectrometry and petrography in the characterization and sourcing
Ancient Neolithic (Linear Pottery Culture) adzes originate from settlements and workshops accompany the neolithization of Belgium. They are made from a wide range of extraregional lithic raw materials such as metamorphic green rocks (amphibolite) and black volcanic rocks (‘basalt’) beside more local or regional raw material as flints, light-coloured (sedimentary and lightly metamorphic) quartzites and fine-grained black rocks. Another material source included black lydites (Cambrian nodular phtanite of Céroux-Mousty and Lower Namurian banded phtanites) and dark grey Lower Namurian silicified sandstones called ‘Micaceous sandstones of Horion-Hozémont’. The discovery of the workshop of Noir Fontaine near the city of Liège in the 1970s and 1980s provides exceptional assemblage available for updating analytical studies. This research focuses on the multi-scale characterization, the discrimination and sourcing of the different types of fine-grained black materials composing Ancient Neolithic adzes found in Belgium. Their black colour results from finely dispersed organic matter, but the absence of palynomorphs does not allow a biostratigraphic ascription. Additional petrographical analyses (Optical Petrography - OP, Scanning Electronic Microscopy - SEM), X-ray diffraction (XRD), chemical analyses (Energy Dispersive Spectroscopy - EDS) and measuring the degree of graphitization of the organic matter through Raman microspectrometry have been decisive in identifying the geological and geographical provenances by comparing the acquired results with geological reference samples collected in the field or through reference collections. The distribution of the different black coloured rocks shows that Cambrian lydites are coming from a very restricted area and were preferred to other more local rock sources.

Article Reference Body length estimation of the European eel Anguilla anguilla on the basis of isolated skeletal elements
Using a large series of dry skeletons of modern European eel Anguilla anguilla (Linnaeus, 1758) from Belgium and the Netherlands, the relationship between fish length and individual bone measurements is investigated. The aim of the study is to provide adequate regression equations between both parameters. This methodology is relevant for both palaeoecological and ecological researches since isolated skeletal elements survive in large numbers on archaeological sites and in the stomach contents, faeces or regurgitations of piscivorous animals. The predictive value for the length estimations is explored for various skeletal elements and the accuracy of the obtained regression formulae is compared to that of the formulae already existing in literature. Particular attention is paid to the use of vertebrae, taking into account that different morphotypes can be distinguished amongst them.

Article Reference Body-size shifts in aquatic and terrestrial urban communities
Body size is intrinsically linked to metabolic rate and life-history traits, and is a crucial determinant of food webs and community dynamics1,2. The increased temperatures associated with the urban-heat-island effect result in increased metabolic costs and are expected to drive shifts to smaller body sizes3. Urban environments are, however, also characterized by substantial habitat fragmentation4, which favours mobile species. Here, using a replicated, spatially nested sampling design across ten animal taxonomic groups, we show that urban communities generally consist of smaller species. In addition, although we show urban warming for three habitat types and associated reduced community-weighted mean body sizes for four taxa, three taxa display a shift to larger species along the urbanization gradients. Our results show that the general trend towards smaller-sized species is overruled by filtering for larger species when there is positive covariation between size and dispersal, a process that can mitigate the low connectivity of ecological resources in urban settings5. We thus demonstrate that the urban-heat-island effect and urban habitat fragmentation are associated with contrasting community-level shifts in body size that critically depend on the association between body size and dispersal. Because body size determines the structure and dynamics of ecological networks1, such shifts may affect urban ecosystem function.
