Article Reference Biofluorescence in Morelia, Malayopython and Python: first reports for the Pythonidae
Ultraviolet (UV) induced biofluorescence in snakes has been underexplored compared to lizards. This study reports for the first time UV fluorescence in several Pythonidae species, including Morelia viridis, Malayopython reticulatus, and Python regius. Specimens were examined under both white and UV light, revealing that UV fluorescence in these snakes is likely skin-based, induced by chemical compounds rather than bone-based as seen in other reptiles. Notably, Morelia viridis and M. azurea exhibited a golden mustard yellow fluorescence, while Malayopython reticulatus displayed a complex pattern with intense yellow fluorescence. The study also found that UV fluorescence is absent in ethanol-preserved specimens, suggesting the degradation of fluorescent compounds during preservation. These findings contribute to the understanding of UV fluorescence in snakes and highlight the need for further research on its functional significance and the specific molecules involved.

Article Reference Molecular methods for the detection and identification of parasitoids within larval wheat midges
Three species of cecidomyiid midges (Diptera: Cecidomyiidae) cause significant yield losses on wheat in Europe: Sitodiplosis mosellana (Géhin), Contarinia tritici (Kirby) and Haplodiplosis marginata (von Roser). Eggs and young larvae may be parasitised by a complex of hymenopteran parasitoids belonging to the Pteromalidae and Platygastridae families which contributes to natural pest control. We have developed molecular tools for detecting and identifying seven parasitoid species previously encountered in Belgium inside individual wheat midge larvae. Barcode DNA sequences from COI, 18S and 28S genes were obtained from the midges and parasitoid species. Each of the three genes allowed all the species to be distinguished although 18S was the only one displaying a barcoding gap, both between parasitoids and midges, and at the species level. Based on the 18S gene, we developed a TaqMan assay to assess parasitism in midge larvae, regardless of the midge and parasitoid species. Next, two group-specific PCR primer pairs were generated, allowing the separate amplification of midge DNA or parasitoid DNA in parasitised individuals and subsequent identification by Sanger sequencing. Finally, species-specific primers were designed to identify six parasitoid species by simple PCR amplification. These tools were successfully applied to assess the parasitism rate of S. mosellana larvae in seven Belgian fields.

Inproceedings Reference Characterization of a multiple burial context from Pachacamac, Peru: complementarity between bioarchaeology and molecular archaeology
Pachacamac is a major precolumbian site located on Peru’s Central Coast. Covering approximately 6 km2, the site was occupied for over a thousand years before the Spanish conquest in the early sixteenth century. In 2012, the Ychsma Project discovered a unique Late Intermediate period (AD 900–1470) multiple burial (“Cx4”) made of two funerary chambers with a vegetal roof structure, containing over 110 intact and fragmentary deceased together with numerous grave goods. More than 60% of the individuals are subadults whose sex cannot be assigned using osteological observation. Among the adults, 23 females and 20 males were identified, and the sex of the remaining four individuals couldn’t be assigned with certainty. We aim to fully understand the sociobiology of the Cx4 population, including biological sex, using a combined bioarchaeology and molecular archaeology approach. Despite significant human modern contamination and low amounts of endogenous ancient DNA, our results show that sex could be assigned genetically in >70% of the cases, including subadults. Sex identification of infants, children and adolescents is crucial to fully understand this complex context and its funerary recruitment, and to perform an integrated and holistic analysis of all associated data.

Inproceedings Reference Paleo-genetic and paleo-pathological studies at Pachacamac: methodological issues and characterization of a multiple burial context (in Spanish)
Pachacamac is a major pre-Columbian site located on Peru’s Central Coast. Covering approximately 6 km2, the site was occupied for over a thousand years before the Spanish conquest in the early 16th century. In 2012, the Ychsma Project excavated a Late Intermediate Period (900 to 1470 AD) multiple tomb (Cx4) made of two funerary chambers covered by a vegetal roof, containing 89 deceased together with numerous grave goods. Over 60% of the individuals are subadults whose sex cannot be assigned based on osteological observations. Ancient DNA (aDNA) analysis can be useful for sex determination, general mitochondrial lineage (haplogroup) and disease diagnosis. However, non-endogenous DNA contamination of archaeological material is a recurrent problematic, since excavation, handling and storage usually don't fit with the precautions recommended for ancient DNA analysis. Nevertheless, we obtained aDNA results from several human individuals recovered from the Cx4 context. Our objectives are to complete the demographic information and to characterize the health status of the population buried in this pilgrimage site dedicated to the eponymous healing god. Despite significant human modern contamination and low amounts of endogenous ancient DNA, our results show that sex could be assigned genetically in >80% of the cases, including subadults. Sex identification of infants, children and adolescents is crucial to fully understand this complex context and its funerary recruitment, and to perform an integrated and holistic analysis of all associated data. The genetic data were also used to estimate the presence of several pathogens using the KrakenUniq taxonomical classification tool.
