Article Reference Large canids at the Gravettian Předmostí site, the Czech Republic: The mandible
Efforts to identify Paleolithic dogs or incipient dogs have been based mainly on examination of complete or nearly complete crania. Complete skulls are, however, very rare in the archaeological record. Because canid mandible are far more frequently found in Pleistocene assemblages, the objective of this study is to investigate whether it is possible to differentiate these jaws by metric and osteomorphological methods in two morphotypes: Paleolithic dogs and Pleistocene wolves. This paper is mainly based on the very rich canid assemblage from the Gravettian Předmostí site in the Czech Republic, but also includes a few mandible from several other European Paleolithic sites. This study provides additional evidence of the existence at Předmostí of the two canid morphotypes. The metric data indicate that the mandible of the Paleolithic dogs are shorter than those from Pleistocene wolves in all tested measurements of length, and the carnassial crown length is shorter in Paleolithic dogs compared with the length of this tooth in Pleistocene wolves. Furthermore, in eight of nine indexes, the Paleolithic dogs differ significantly from the Pleistocene wolves. The mandible of Paleolithic dogs differ also in non-metric features from the Pleistocene wolves: they present a high frequency of crowded premolars and backwards-oriented apex of the coronoid. This paper furthermore confirms that Paleolithic dogs occur at two late Upper Paleolithic sites (Eliseevichi, Verholenskaya) where previous studies had indicated their presence. In addition, we document the presence of Paleolithic dogs at another Gravettian site, Kostenki-8.

Article Reference Diversity and environmental control of benthic harpacticoids of an offshore post-dredging pit in coastal waters of Puck Bay, Baltic Sea
Placer extraction in Puck Bay, a shallow (3 m depth) area of the Baltic Sea, resulted in the formation of post-dredging pits. Such dredging activities led to a considerable local disturbance of the soft-bottom communities. Topography and sedimentary characteristics of the disturbed area have been radically changed. It is therefore a matter of concern as to whether these alterations to the environment resulted in any serious permanent changes to the biological communities in the affected areas. Benthic copepod assemblages were examined 10 years after termination of placer digging in one of the post-dredging pits and compared with the fauna in a natural depression (Kuźnicka Hollow) and on the shallow sandy bottom surrounding the pits. Samples were collected on four occasions in 2001–2003. This study has generated ecological information on the status of harpacticoid species inhabiting the dredged and undredged areas in the vicinity. Analyses of data showed that the sampling stations differed significantly, during all the sampling events, in harpacticoid abundance, taxonomic composition and Shannon–Wiener diversity index. The natural depression and the shallow sandy bottom of Puck Bay were found to support specific harpacticoid assemblages. Interstitial and sand-burrowing species (e.g. Paraleptastacus spinicauda) dominate the shallow sandy bottom, and the Kuźnicka Hollow is inhabited mainly by epibenthic and silt-burrowing species (e.g. Halectinosoma curticorne, Tachidius discipes, Microarthridion littorale). The post-dredging pit assemblage showed the presence of epibenthic species, e.g. Tachidius discipes, Dactylopusia euryhalina, and Stenhelia palustris, passively transported into the pit by wave action and currents, possibly with algal mats and/or plant remains. The taxonomic composition and occurrence of harpacticoid species in the post-dredging area is therefore random and accidental.

Article Reference Biodiversity of Belgian groundwater fauna in relation to environmental conditions
1. The Pleistocene glaciations during the Quaternary appear to have resulted in an impoverished groundwater fauna in northern Europe. Re-colonisation may have occurred either through long-distance dispersal from unglaciated southern areas or from local refugia. 2. The Belgian groundwater fauna was sampled at multiple sites, and its habitats characterised, to assess whether the composition of present-day stygobiotic assemblages can be attributed to either of these mechanisms. 3. A total of 202 sampling sites were selected in four hydrogeographic units of the Meuse River catchment. Sites were equally divided among the saturated and unsaturated zones of fractured aquifers (karst) and within the hyporheic and phreatic zones of porous aquifers. Seventeen environmental parameters were determined in parallel. 4. More than 140 species were recorded, including representatives of the Amphipoda, Cladocera, Copepoda, Hydrachnidia, Isopoda, Oligochaeta, Ostracoda, Mollusca, Syncarida and Nematoda. Thirty stygobiont specieswere identified, of which10 species were new to the Belgian fauna, raising the total number of stygobiotic species in Belgium to 41. 5. The frequency of occurrences of stygobiotic species was always low, with 37% of the sampled sites lacking stygobionts. A few species were exclusive to one hydrological zone, although no statistically significant differences were detected in species richness at any of the four hierarchial levels considered (Meuse catchment = region, hydrogeographic units, aquifer type and hydrological zone). 6. Overall, results suggest that the stygobiotic fauna of Belgium is species-poor and mostly comprises widely distributed species with broad ecological tolerances. This supports the view that eurytopic species re-colonised the area by long-distance dispersal from refugia in southern Europe. The virtual absence of endemic species further suggests that the scenario of an ancient fauna that survived in local refugia is of minor importance.
