Article Reference Sex in the city: uncovering sex-specific management of equine resources from prehistoric times to the modern period in France
Sex identification from fragmentary archeozoological assemblages is particularly challenging in the Equid family, including for horses, donkeys and their hybrids. This limitation has precluded in-depth investigations of sex-ratio variation in various temporal, geographic and social contexts. Recently, shallow DNA sequencing has offered an economical solution to equine sex determination, even in environments where DNA preservation conditions is not optimal. In this study, we applied state-of-the-art methods in ancient DNA-based equine sex determination to 897 osseous remains in order to assess whether equal proportions of males and females could be found in a range of archeological contexts in France. We found Magdalenian horse hunt not focused on isolated bachelors, and Upper Paleolithic habitats and natural traps equally balancing sex ratios. In contrast, Iron Age sacrificial rituals appeared to have been preferentially oriented to male horses and this practice extended into the Roman Period. During Antiquity, the Middle Ages and the Modern Period, cities emerged as environments largely dominated by horse males. This strong sex-bias was considerably reduced, and sometimes even absent, in various rural contexts. Combined with previous archaeozoological work and textual evidence, our results portray an urban economy fueled by adult, often old, males, and rural environments where females and subadults of both sexes were maintained to sustain production demands.

Book Reference Shallow-water Holothuroidea (Echinodermata) from Kenya and Pemba Island (Tanzania)
A total of 225 specimens - representing three orders, four families, 12 genera, 44 species and one variety - collected in the shallow-waters of Kenya and Pemba Island (Tanzania) - are investigated. Bohadschia cousteaui, B. similis, Holothuria (Metriatyla) albiventer; Pearsonothuria graeffei, Thelenota anax, Euapta godeffioyi, Opheodesoma grisea, 0. spectabilis and Synaptula recta are new records for Kenya and from Pemba Island (Tanzania). H. (M) timana is a new record for the western Indian Ocean. Diagnostic characters and descriptions (including some brief notes on the ecology) are given for most species. Identification keys up to the species level are also included. The results are compared to the shallow-water holothuroid biodiversity of the western Indian Ocean. This study stresses the richness of the holothuroid biodiversity of Kenya and Pemba Island. The holothuroid fauna of Kenya (with Pemba Island) is now represented by 48 species.

Article Reference Short-term changes in the structure of ant assemblages in a Guinean savanna under differing fire regimes at Lamto Scientific Reserve, Côte d’Ivoire
To maintain savanna vegetation, mid-seasonal fire has been applied since 1961 in the Lamto Savanna (Côte d’Ivoire). However, this prescribed fire has not impeded tree encroachment during recent years, nor have its effects on insect assemblages been documented. Also the impact of tree intrusion on insect assemblages is poorly studied in savanna. To prevent tree density increasing, a change in fire regime might be a solution. In this study, we examined the effect of different fire regimes (early, mid-seasonal and late fires) on leaf-litter ant assemblages in order to suggest appropriate measures for preventing tree invasion without having an effect on insect communities. Sampling was implemented by combining pitfall trapping and leaf-litter sampling before and after three different fire regimes, early, mid-seasonal and late fires. While the ant species richness declined after the passage of early and mid-seasonal fires, significantly more species were found in the burnt savanna after the late fire. However, the losses or gains of species due to different fire regimes did not cause severe changes in the ant species composition. Of the functional groups identified, only the generalists and specialist predators were respectively strongly affected by the early and mid-seasonal fires, certainly due to micro-habitat modification. Based on the trends observed in the present study, we suggest sampling other invertebrate fauna in similar savanna plots to find out if other insect groups have similar reactions to the applied fire regimes.

Article Reference Silpha tyrolensis Laicharting, 1781 (Coleoptera: Silphidae), an unexpected addition to the Belgian fauna
In the course of the Belgian Silphidae Project, four specimens of Silpha tyrolensis Laicharting, 1781 were encountered when studying the unidentified Silphidae in the entomological collection of the Haute École Provinciale de Hainaut-Condorcet in Ath. These are the first records of this species for Belgium and are from the period 1990–2010. Subsequent recent trapping in the region where the specimens were found revealed no additional specimens. In this paper the records are presented and the distribution of the species in Belgium and Europe is mapped and discussed.
