The distribution and coexistence of gill ectoparasites of 121 specimens of Cephalopholis argus Bloch et Schneider, caught between October 1994 and October 1995, were investigated. Adults of the monogenean Benedenia sp. and copepod Hatschekia sp., the larval caligid copepod Caligus sp. (copepodite and chalimus stages), and praniza larvae of the isopod Gnathia sp. were found. All species were aggregated within the host population. Infracommunities were poor, with only 40.5% of fish infected by two parasite species. Only two individual fish harboured all the parasite species observed at the component community level. Prevalences were less than 50% and mean intensities were low (less than 6 parasites/host). No dominant parasite species were observed in the host population. The spatial distribution of each parasite species was studied on different partitions of the gill arches. Adult parasite stages that are mobile showed much overlap in their distribution, whereas temporarily attached larvae of Caligidae were more site specific. Copepodite and chalimus larvae showed niche restriction that is probably due to gregarious behaviour. Positive associations between caligid larvae reflected intraspecific interaction for site and/or resources. Each of the Caligus sp. larval stages prefers specific sites, as do the adults, which occur exclusively in the buccal cavity of the host. Infracommunities were too poor and too few to induce processes of interspecific competition.
A salvage excavation was conducted in harsh conditions to recover stone structure E (KSE). In spite of a very short time window available for digging, an area of 20 m2 was completely excavated and the entire structure (KSE) was carefully documented. Spatial distribution of artifacts closely follows the boundary of the paved area. The raw material spectrum is characterized by prevailing rock crystal, supplemented by quartz, plasma, erratic flint, radiolarite, smoky quartz and Krumlovský les-type chert. The artifacts are similar to those recovered from KSA and KSB, including carinated atypical endscraper- cores, bipolar anvil cores, and Sagaidak-Muralovka-type microliths. A detailed analysis of granulite used to construct the pavement structure indicates smoothing, abrasion, pounding marks, and flake removals – they probably served as pads for activities that we have not identified as yet.
