Conference Reference Connectivity and genetic structure of flatfish for fisheries management and traceability in Belgium.
Early life stages are critical in determining connectivity. Effective fishery management requires understanding of how spawning grounds and nurseries are connected and what processes influence larval retention and dispersal. These mechanisms maintain a high genetic diversity which is essential to grantee population resilience to environmental changes. Marine populations are often believed to be panmictic because there are few obvious barriers to gene flow in the ocean. However, recent work based on Next Generation Sequencing has shown that even highly mobile species have a population structure at reduced spatial scale. Once determined, population structure is the best level to monitor fish stocks. Each population has its own genetic signature therefore traceability system in the industry would highly benefit from a precise mapping and monitoring of stocks, especially for sole in the North Sea. Given its commercial importance in the North Sea fishery, a larger effort has to be made to preserve the flatfish valuable resource. In this project we will address the following questions: 1- Does larval dispersal vary in time and space? 2- What biotic and abiotic factors are driving larval connectivity? 3- Can we define sub-populations based on connectivity patterns? A suite of 1536 SNPs (Single Nucleotide Polymorphisms) and state-of-the-art genotyping (Illumina Golden Gate genotyping) have been employed to investigate the genetic population structure of sole larvae and post-larvae at the European scale. We have obtained four groups: (1) a mixed group with populations within the North Sea and eastern English Channel; and the three most geographically extreme populations were clearly separated: (2) the German Bight on one side and (3) the Celtic Sea and (4) the Irish Sea on the other side. Finally, results of hydrodynamic individual based model of larval dispersal developed by Lacroix and collaborators will be compared to collected da¬ta in order to investigate the role of selected biotic and abiotic factors in driving connectivity. Temporal variability will be studied combing three years of intensive sampling and historical data spanning the last two decades. Overall, this study will help the sustainable management of fishery by defining significant ecological units, while the molecular markers will allow tracing any fish present on the market to its origin, hence fighting illegal fishing and enabling efficient traceability.

Article Reference COnservation management of POlar ecosystems (COPE project): using genomic approaches to study connectivity in Antarctic fishes and amphipods, across spatial and functional scales
The unique cold-adapted ecosystems of the Southern Ocean are threatened by rapid environmental change and increasing anthropogenic impact. Marine protected areas (MPAs), areas of ocean where human activities are limited or prohibited, have been increasingly promoted as a tool for mitigating ocean threats and conserving biodiversity. National governments and the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) is progressing towards establishing a representative network of MPAs in the Southern Ocean. Connectivity is now widely recognized to be a crucial variable for the design and management of MPA networks through the effects that movements of individuals and genes have on population viability, metapopulation persistence, and resilience to disturbance. The understanding of connectivity patterns is required to prioritize the allocation of conservation effort towards, for instance, areas acting as central connection nodes in a network of MPAs. The COPE project aims to advance the understanding of genetic connectivity and adaptation in key benthic and pelagic Antarctic organisms (crustaceans and actinopterygian fishes) using population genomic approaches (ddRAD sequencing). Thousands of genomic variants were used in two model genera, the Charcotia amphipod and the Trematomus fishes, to provide estimates of neutral and adaptive genetic variation and structure at different trophic levels and at a circumpolar scale. The results of the COPE project will contribute to our understanding of the spatial and functional distribution of biological variation in the Southern Ocean, required to develop suitable management and conservation strategies through CCAMLR.

Proceedings Reference Consumption patterns and living conditions in 18th century rural nunnery: an interdisciplinary study on the latrine of Clairefontaine (south-eastern Belgium) with special attention to botanical remains
The abbey of Clairefontaine, situated near Arlon in Belgium, was founded in the 13th century and destroyed during the French Revolution at the end of the 18th century. Although the abbey buildings were largely dismantled after the suppression of the community, archaeological research revealed the underground remains of the 18th century monastery. A latrine was discovered on the south side of the monastic complex and excavated for a detailed interdisciplinary study. Plenty of macro-botanical and faunal remains, glass and pottery have indeed been found throughout the profile; analyses of plant micro-remains were also performed. The major part of the archaeological remains dates between the second quarter and the end of the 18th century. Built over a narrow stream, the latrine underwent regular waste evacuation by the inflow of water. It is then supposed to give an insight into cabinet of the last generation of sisters present at Clairefontaine. A clear stratification is however observed with five different units delivering contrasted archaeobiological results. We will focus here on the archaeobotanical data, which will be discussed in detail and compared with archaeozoological and historical studies, in order to illustrate the lifestyle and the consumption in a rural nunnery from the 18th century.
