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.

Conference Reference Base du crâne, labyrinthe osseux et dimorphisme sexuel : investigation morphométrique au sein d’un échantillon d’Europe de l’Ouest
L’estimation du sexe biologique d’un individu constitue une étape primordiale de l’analyse anthropologique, que ce soit en contexte archéologique ou forensique. Elle doit se fonder sur des méthodes de diagnose sexuelle reproductibles, fiables et validées. Néanmoins, cette tâche peut s’apparenter à un véritable défi lorsque la préservation des éléments diagnostiques osseux n’est pas optimale, et ce d’autant plus s’il s’agit de restes immatures ou brûlés. Face à de tels restes fragmentés, une voie prometteuse consisterait à mettre en place une méthode de diagnose sexuelle s’appuyant sur un élément osseux à la fois fortement dimorphique et à la survie taphonomique avérée. Alliant ostéométrie et outils digitaux au travers d’une approche strictement morphométrique, cette recherche propose d’évaluer le dimorphisme de la base du crâne (i.e., os occipital et temporaux) et celui du labyrinthe osseux de l’oreille interne sur un assemblage osseux comprenant 611 crânes et 121 labyrinthes appartenant à des sujets européens – immatures et adultes – d’âge et de sexe connus. Les résultats obtenus dans cette étude démontrent d’une part que le dimorphisme sexuel de l’os temporal est plus marqué que celui de l’os occipital, et ce dès la phase pubertaire, et d’autre part qu’il n’est pas possible d’établir une méthode de diagnose sexuelle indépendante de l’âge sur le labyrinthe osseux du fait des différences d’expression de son dimorphisme sexuel observées entre les immatures et les adultes. En outre, ce travail a permis d’établir plusieurs modèles prédictifs de diagnose sexuelle à partir de la base du crâne adulte (avec de 77 à 87 % de classification correcte), du labyrinthe osseux adulte (de 76 à 83 %) et du labyrinthe immature (de 76 à 84 %). Leurs qualités intrinsèques (i.e., reproductibilité, fiabilité, facilité d’utilisation et faible coût) en font des outils de diagnose sexuelle adaptés à l’examen de restes osseux fragmentaires.

Techreport Reference Bats in the Belgian part of the North Sea and possible impacts of offshore Wind Farms. in: Degraer, S. et al. (Ed.) (2016). Environmental impacts of offshore wind farms in the Belgian part of the North Sea: Environmental impact monitoring reloaded.
Several species of bats in northern Europe undertake seasonal migrations between their summer roosts and wintering areas. Doing so, they are known to cross open sea in some cases. Taking account of the increase of wind farms in the Belgian part of the North Sea and the entire North Sea, the lack of information on the spatio-temporal distribution of bats in Belgian waters and the results of some studies (onshore) demonstrating wind turbines can cause high mortalities in bats, a taxon in global decline, it is important to quantify the risk of offshore wind farms in the North Sea to threaten bat populations. To investigate bat distribution, we installed an automated acoustic recorder on the Belgian research vessel ‘Belgica’ to record bats while the vessel is at sea at night. The acoustic detector on the Belgica was operational during 93 nights in autumn 2014 and spring 2015, hence covering two full bat migration periods. In autumn 2014, 117 call sequences were registered in the BPNS, belonging to four different species. In spring 2015, only four sequences were registered, all during one night. The few recordings were all registered during only three nights. These results are not sufficient to solidly determine spatio-temporal patterns of bats in the BPNS, but allow drawing some preliminary conclusions on their frequency of occurrence and distribution at sea. In 2015 and 2016, a network of nine Batcorders is collecting data in the Dutch and Belgian part of the North Sea and along the coastline. This detector network will increase our knowledge about the impact of offshore wind farms on bats as it will increase the number of detections of bats at sea and will allow direct comparison between data collected at the different locations, without seasonal or meteorological bias. This will allow addressing the question if bats are attracted to or avoid offshore wind farms. This may then lead to appropriate management or mitigation measures.
