Article Reference Barcoding and traditional health practitioner perspectives are informative to monitor and conserve frogs and reptiles traded for traditional medicine in urban South Africa
Previous literature suggests that Indigenous cultural practices, specifically traditional medicine, are commonplace among urban communities contrary to the general conception that such practices are restricted to rural societies. We reviewed previous literature for records of herptiles (frog and reptile species) sold by traditional health practitioners in urban South Africa, then used visual confirmation surveys, DNA barcoding and folk taxonomy to identify the herptile species that were on sale. Additionally, we interviewed 11 IsiZulu and SePedi speaking traditional health practitioners to document details of the collection and pricing of herptile specimens along with the practitioners' views of current conservation measures for traditional medicine markets. The 34 herptile species recorded in previous literature on traditional medicine markets included endangered and non-native species. Spectrophotometry measurements of the DNA we extracted from the tissue of herptiles used in traditional medicine were an unreliable predictor of whether those extractions would be suitable for further experimental work. From our initial set of 111 tissue samples, 81 sequencing reactions were successful and 55 of those sequences had species-level matches to COI reference sequences on the NCBI GenBank and/or BOLD databases. Molecular identification revealed that traditional health practitioners correctly labelled 77% of the samples that we successfully identified with DNA barcoding in this study. Our mixed methodology approach is useful for conservation planning as it updates knowledge of animal use in Indigenous remedies and can accurately identify species of high conservation priority. Furthermore, this study highlights the possibility of collaborative conservation planning with traditional health practitioners.

Article Reference Preference for fish in a Neolithic hunter-gatherer community of the upper Tigris, elucidated by amino acid δ15N analysis
We report here the stable nitrogen isotope composition (d15N) of individual amino acids and the d15N and d13C content of collagen from human and faunal remains collected from Hasankeyf H€oyük, an early Neolithic site in the upper Tigris valley. Based on the d15N of collagen only, the contributions of freshwater resources to the diet of the hunter-gatherers were difficult to clearly identify relative to terrestrial resources. However, analysis of the nitrogen isotope composition of individual amino acids enabled the identification of minor contributions from freshwater resources to the diet in a community primarily dependent on terrestrial resources. Individual variability suggested that some individuals at Hasankeyf H€oyük used freshwater resources, whereas others probably depended primarily on terrestrial food resources. The importance of freshwater resources as food for this hunter-gatherer community was variable among groups and depended on burial location and time of burial.

Article Reference CO2-enhanced oil recovery and CO2 capture and storage: An environmental economic trade-off analysis
CO2 enhanced oil recovery can play a significant role in stimulating carbon capture and storage because of additional oil revenues generated. However, it also leads to additional greenhouse gas emissions. We estimate the global warming potential of different CO2 capture scenarios with and without enhanced oil recovery. During a 10 year period in which oil and electricity are produced without CO2 being captured, the global warming potential is 11 MtCO2 equivalents. We show that if CO2 is captured and used for 15 years of enhanced oil recovery, the global warming potential decreases to 3.4 MtCO2 equivalents. This level is 100% higher compared to the scenario in which the captured CO2 would be stored in an offshore aquifer instead. If the capture of CO2 is stopped when the oil reservoir is depleted, the global warming potential resulting from 10 years electricity production is 6 MtCO2 equivalents. However, if CO2 is stored in the depleted reservoir, the global warming potential is six times lower during that period. Electricity production and oil refining are the main contributors to the global warming potential. The net present value analysis indicates that for CO2 prices lower than or equal to 15 €/t and oil prices greater than or equal to 115 €/t, it is most profitable to capture CO2 for enhanced oil recovery only. Because of the low CO2 price considered, large incomes from oil production are required to stimulate CO2 capture. The environmental economic trade-off analysis shows that if CO2-enhanced oil recovery is followed by CO2 capture and storage, costs increase, but the net present value remains positive and the global warming potential is reduced. Authorities could use these outcomes to support the development of economic mechanisms for shared investments in CO2 capture installations and to mandate both oil producer and large CO2 emitting firms to store CO2 in depleted oil fields.

Article Reference Octet Stream Reply to Van Peer: Direct radiocarbon dating and ancient genomic analysis reveal the true age of the Neanderthals at Spy Cave
Van Peer (1) contests the conclusions of our article on Neanderthal disappearance in Northwest Europe (2), but we think his argument may reflect a misunderstanding of the stratigraphy at Spy Cave and/or incomplete reading of our article. We provide here a response to his arguments.The idea that the discovery time of the Neanderthal bones impacts the results is not scientifically valid and indicates an incomplete review of the literature. Among the oldest radiocarbon dates obtained on the Spy Neanderthals are those measured on collagen from material collected on the slope: Spy 737a (OxA-10560) and Spy 94a (GrA-32623) (3, 4). In addition, although found on the slope, the maxillary …

Article Reference Sexing the bony labyrinth: A morphometric investigation in a subadult and adult Belgian identified sample
In forensic anthropology, sex estimation is a fundamental step in assessing individual biological profiles when analyzing human skeletons. Yet, current methods are not reliable enough to allow an accurate sex identification of highly fragmented, burnt, or subadult remains. This paper aims to investigate sexual dimorphism of the bony labyrinth on both identified subadult and adult individuals. The bony labyrinth is of particular interest for sex estimation since it is alleged to complete size and maturation pre-pubertally and is located inside the petrous part of the temporal bone which protects it from taphonomic processes. The study was performed on 93 CT scans of identified individuals from two Belgian osteological collections (19-20th century) and from current pediatric images (Erasme hospital, Brussels). Linear and angular measurements were taken on 2D slices of right bony labyrinths. Intra- and interobservers error measurements were calculated. Statistical tests were used to unravel any morphological variations between subadult and adult bony labyrinths and to highlight differences between females and males, separately in subadults and adults. Linear discriminant functions were established by cross-validation and tested on an independent sample from Belgium. Some measurements were significantly different between subadults and adults, and between females and males within both subadult and adult samples. Univariate functions achieved 72.7% in subadults and 68.4% in adults whereas multivariate equations increased accuracy respectively up to 84.9% and 78.4%. This study entails promising results to design a sex estimation method suitable for fragmented and/or subadult remains. Further metric approaches are needed to explore bony labyrinth sexual dimorphism.
