The Democratic Republic of the Congo has the highest diversity of ant species in the Afrotropical region, even though it remains largely understudied in the modern era. The aim of this study is to report on an inventory of the litter ants from the Yangambi Biosphere Reserve in the Tshopo Province, north of the Congo River. Three habitats (fallow, secondary forest and primary forest) were sampled at six localities. A total of 190 ant species belonging to 50 genera and 8 subfamilies, have been recorded in the Yangambi biosphere region. Besides, 96 species were added to Tshopo Province, bringing the total to 306, a 44% increase; and we added 55 species to the already diverse Democratic Republic of the Congo, raising the total record to 791 species, a 7% increase. At least 10% of the collected species are new to science.

There is ample evidence of human occupation across Northern Europe throughout various periods of the Upper Paleolithic. However, the biological characteristics of the Northern European Upper Paleolithic humans and their mortuary practices remain largely unknown because of a dearth of human fossils. In Belgium, although the presence of humans has been verified at multiple archeological sites, no Upper Paleolithic fossil has yet been identified. In this context, the recent discovery of Upper Paleolithic human remains at Goyet (Belgium) fills in an important chronological gap. The “Troisième caverne” of Goyet, excavated at the end of the 19th and early 20th century, yielded a rich archeological sequence ranging from the Middle and Upper Paleolithic to historical times. In 2008, we began documenting the Paleolithic occupations of the “Troisième caverne” by reassessing the collections from the site which heretofore had only been partially studied. The updated inventory of human remains was accomplished by conducting a detailed sorting of the paleontological collections in order to identify human remains that may have been overlooked thus far. As a result, the collections from the “Troisième caverne” now include nearly 200 human bones/bone fragments and isolated teeth that correspond to various materials from different periods. The morphometric study of the human specimens from Goyet, completed by direct radiocarbon dating and stable isotope analysis, shows that they represent two main samples—a series of Late Neandertal remains (Rougier et al. 2012) and a set of modern human specimens from three periods of the Upper Paleolithic, namely the Aurignacian, Gravettian, and Magdalenian. The latter include fragmentary elements from the cranial and infracranial skeleton. Interestingly, those from the Gravettian and Magdalenian present anthropogenic traces and ochre traces. We will discuss the importance of these new fossils in the context of the human population of Northern Europe during the Upper Paleolithic.
