Article Reference Have birds ever mattered? An evaluation of the contribution of avian species to the archaeozoological record of Belgium (Iron Age to recent times)
This preliminary study aims to document general trends in the representation of bird remains in anthropogenic contexts from Belgian archaeological sites. A large dataset is analysed, consisting of 186 faunal assemblages from 79 different sites. The contexts included vary in terms of their taphonomic nature (refuse layers, latrines, pits, etc.) and date, ranging from the Iron Age to the modern period. The characteristics of the study area and the dataset as a whole are described, with a focus on identification rates, past and present avian taxonomic diversity, and relative abundance of bird remains compared with domestic mammal remains. The impact of recovery methods (sieving or hand collecting) on these various aspects is also evaluated. A taxonomic analysis describes the diversity and abundance of the different groups of species that are encountered and shows which habitats were preferentially exploited for the hunting of wild birds. The study shows that there is significant taxonomic diversity across the dataset. However, this diversity is not necessarily present in each separate archaeological context, as the number of remains identified by taxon is generally low. Some species or groups of species are ubiquitous and dominant, in particular domestic fowl. Although this analysis is broad and exploratory, it is believed that it will serve as a sound methodological basis for future, more detailed studies focusing on the role that birds played in past human societies during specific chronological periods.

Article Reference Healed mid-shaft fracture of an Early Roman bovine femur
We evaluated a healed fracture that was observed in the shaft of a bovine femur from an Early Roman settlement context at the site of Wange, Belgium. Using external observation and X-ray images, the specimen is described, paying particular attention to displacement of the bone ends, shortening of the bone, and callus formation. Similar fractures seen in femora of a modern Derby’s antelope (Taurotragus derbianus) and of a modern eastern lowland gorilla (Gorilla gorilla graueri) are described, and we discuss why the incidence of healed femur fractures is so limited in large mammals.

Article Reference Hematodinium perezi (Dinophyceae: Syndiniales) in Morocco: The First Record on the African Atlantic Coast and the First Country Record of a Parasite of the Invasive Non-Native Blue Crab Callinectes sapidus
Dinoflagellates belonging to the genus Hematodinium are key parasites of marine crustaceans, primarily decapods. In this study, we document the first report of H. perezi Chatton & Poisson, 1930 on the African Atlantic coast. This is also the first parasite record in the invasive non-native Atlantic blue crab Callinectes sapidus Rathbun, 1896 in Morocco. Specimens of C. sapidus were sampled in winter 2023 from two Ramsar sites on the Moroccan Atlantic, namely Merja Zerga and Oualidia Lagoons, and were screened to detect the presence of parasites in their hemolymph. Based on staining fresh hemolymph smears, we did not detect Hematodinium in any of the 36 investigated individuals (20 and 16 from Merja Zerga and Oualidia Lagoons, respectively), probably due to methodological artifacts. The PCR-based method was revealed to be more accurate in diagnosing the Hematodinium parasite. It showed that at Merja Zerga Lagoon, 13 individuals of C. sapidus were infected by the parasite (prevalence: 65%) in comparison to four at Oualidia Lagoon (25%). Genetic analysis, based on the ITS1 rDNA gene from Hematodinium, confirmed the sequences as being those of Hematodinium perezi.

Article Reference Hidden biodiversity in an ancient lake: phylogenetic congruence between Lake Tanganyika tropheine cichlids and their monogenean flatworm parasites
The stunning diversity of cichlid fishes has greatly enhanced our understanding of speciation and radiation. Little is known about the evolution of cichlid parasites. Parasites are abundant components of biodiversity, whose diversity typically exceeds that of their hosts. In the first comprehensive phylogenetic parasitological analysis of a vertebrate radiation, we study monogenean parasites infecting tropheine cichlids from Lake Tanganyika. Monogeneans are flatworms usually infecting the body surface and gills of fishes. In contrast to many other parasites, they depend only on a single host species to complete their lifecycle. Our spatially comprehensive combined nuclear-mitochondrial DNA dataset of the parasites covering almost all tropheine host species (N = 18), reveals species-rich parasite assemblages and shows consistent host-specificity. Statistical comparisons of host and parasite phylogenies based on distance and topology-based tests demonstrate significant congruence and suggest that host-switching is rare. Molecular rate evaluation indicates that species of Cichlidogyrus probably diverged synchronically with the initial radiation of the tropheines. They further diversified through within-host speciation into an overlooked species radiation. The unique life history and specialisation of certain parasite groups has profound evolutionary consequences. Hence, evolutionary parasitology adds a new dimension to the study of biodiversity hotspots like Lake Tanganyika.
