Inproceedings Reference Supporting the One Health approach in Belgium: identification of policy-relevant organisms and tissues by BopCo
Accurate species identification is crucial in the One Health framework because it underpins the ability to effectively monitor, prevent, and mitigate the emergence and spread of human and animal infectious diseases and zoonoses. Moreover, misidentification can lead to inadequate risk assessments, allowing infectious agents or invasive alien species to spread undetected, thereby threatening biodiversity, ecosystem stability, and public health. BopCo is a Belgian research unit that provides such accurate identifications of organisms and biological tissues with relevance for policy and decision-making processes. It is jointly run by the Royal Belgian Institute of Natural Sciences and the Royal Museum for Central Africa, and has access to extensive reference collections, expert taxonomists, and a comprehensive research infrastructure. BopCo uses morphology and DNA-based approaches to handle on-demand species identification requests, and it is a partner on various projects within the One Health context. In this framework, BopCo contributes to identifying the introduction pathways and dispersal dynamics of two invasive mosquito species in Belgium, Aedes albopictus and Ae. japonicus, as part of the MEMO+ project in collaboration with Sciensano and the Institute of Tropical Medicine. Using various DNA identification techniques, BopCo verifies the species identity of the exotic mosquitoes collected at multiple points of entry. Similarly, the Medical Component of the Belgian Armed Forces is investigating the Culicidae mosquito biodiversity at foreign deployment sites. BopCo takes part in this project by providing DNA-based identifications to support the Laboratory for Vector-Borne Diseases of the Queen Astrid Military Hospital. Accurate identification of the various mosquito species is important since they are known vectors of pathogens of significant public health concern such as Western Nile virus, Plasmodium parasites, and dengue virus. Furthermore, BopCo is involved in the monitoring of (exotic) animal product imports into Belgium within the INTERCEPT project, in collaboration with the University of Antwerp. Within this project, meat intercepted from passenger’s luggage at Brussels Airport was sampled and identified using DNA barcoding to prevent the import of transmittable animal diseases and the introduction of invasive alien species. Finally, BopCo contributed to the discovery of the first occurrence of Trichobilharzia regenti in Belgium, a blood parasite of birds, which may try to infect humans, triggering painful skin lesions known as “swimmer’s itch”. Following a reported case in Kampenhout, Belgium, researchers at the Royal Museum for Central Africa and KU Leuven captured freshwater snails (the intermediate hosts) and performed a shedding experiment, after which BopCo used a DNA analysis to identify the shed parasites, unveiling the presence of T. regenti. BopCo continually seeks partnerships with research institutes and government agencies to deliver accurate species identifications within a One Health framework and other policy-relevant research contexts.

Article Reference Surface movement above old coal longwalls after mine closure
Although most subsidence occurs in the months and years after mining by the longwall method, surface movement is still occurring many decades after the mining. The aim of the study is to quantify the long term behavior. Satellite data (radar-interferometry) were analyzed to study an area of about 2km2 during the 18years following the closure of the underground infrastructure and the flooding of the underground workings and rock mass. It was observed that, on average, a residual downward movement took place till 7–12years after the closure, followed by a clear uplift. However, the first signs of an uplift occurred in certain sub-areas 3–4years after the closure. Zones within the area studied were identified with either larger or smaller movements. However, the spatial variation of the surface subsidence or uplift could not be directly explained by the characteristics of mining.

Article Reference Survey on the distribution of the Sweet potato weevil, Cylas species-complex in Ghana (Coleoptera: Brentidae)
The Sweet potato weevils of the genus Cylas are the most destructive pests of sweet potato and are widely distributed in Africa. The aim of this study was to identify and document the species of Cylas occurring in sweet potato production zones in Ghana. A survey was conducted in 23 localities in 2015 from July to December in seven regions in Ghana in order to determine the identity of the pest. We collected nine thousand and two specimens from Central, Eastern, Greater-Accra, Northern, Volta, Upper-East, and the Upper-West regions. Two species were identified: Cylas brunneus Fabricius, 1797 and Cylas puncticollis Boheman, 1833. Cylas puncticollis occurred in all regions and represented 6,107 specimens (68%), while 2,895 of the specimens (32%) could be assigned to C. brunneus. The latter is restricted to the southern sector including Volta, Central, Eastern and Greater Accra Regions. When considering both species in the southern sector, the Volta Region accounted for 3,117 specimens (48%) followed by 1,447 (22%), 987 (15%), and 980 (15%), from the Central, Eastern, and Greater-Accra Regions, respectively. The dominant species in southern and northern sector was C. puncticollis.

Article Reference Synergy between polar-orbiting and geostationary sensors: Remote sensing of the ocean at high spatial and high temporal resolution
Ocean colour sensors have been capturing the state of the world's oceans for over a decade. They are typically installed on polar-orbiting satellites and cover the entire earth every 1 to 2 days. This temporal resolution is insufficient to observe oceanic processes occurring at a higher frequency, especially when taking cloud cover into account. Data from geostationary platforms can be obtained with a much better temporal resolution (images every 15 or 60 min), and thus are useful to study those processes. We show that by synergistically combining marine reflectance data from SEVIRI, a geostationary sensor, and MODIS Aqua, a polar orbiter, the resulting product is an improvement over both data sources. The synergy approach takes the reflectance from MODIS, with high quality and high spatial resolution, and modulates this over the day by the temporal variability of the SEVIRI reflectance, normalized to the SEVIRI reflectance at the time of MODIS overpass. The temporal frequency of the synergy product is much better than that of MODIS, and by using the latter's high quality data, the limited spatial and radiometric resolution of SEVIRI is enhanced. As the SEVIRI data is limited to a single broad red band (560-710 nm), the applications of the synergy product are limited to parameters that can be derived from this band, such as suspended particulate matter (SPM), turbidity (T) and the diffuse attenuation of photosynthetically available radiation (Kpar) in turbid waters. A geostationary ocean colour sensor over Europe will provide invaluable data concerning our marine environment. The cost of increasing the spatial resolution of a geostationary sensor is very high, and this study illustrates that a lower resolution geostationary ocean colour sensor combined with a high resolution polar orbiting sensor, can provide a high frequency synergetic product with high spatial resolution.
