Article Reference Threshold indicators of primary production in the north-east Atlantic for assessing environmental disturbances using 21 years of satellite ocean colour
Primary production (PP) is highly sensitive to changes in the ecosystem and can be used as an early warning indicator for disturbance in the marine environment. Historic indicators of good environmental status of the north-east (NE) Atlantic and north-west (NW) European Seas suggested that daily PP should not exceed 2–3 g C m−2 d−1 during phytoplankton blooms and that annual rates should be 300 g C m−2 yr−1. We use 21 years of Copernicus Marine Service (CMEMS) Ocean Colour data from September 1997 to December 2018 to assess areas in the NE Atlantic with similar peak, climatology, phenology and annual PP values. Daily and annual thresholds of the 90th percentile (P90) of PP are defined for these areas and PP values above these thresholds indicate disturbances, both natural and anthropogenic, in the marine environment. Two case studies are used to test the validity and accuracy of these thresholds. The first is the eruption of the volcano Eyjafjallajökull, which deposited large volumes of volcanic dust (and therefore iron) into the NE Atlantic during April and May 2010. A clear signature in both PP and chlorophyll-a (Chl a) was evident from 28th April to 6th May and from 18th to 27th May 2010, when PP exceeded the PP P90 threshold for the region, which was comparatively more sensitive than Chl a P90 as an indicator of this disturbance. The second case study was for the riverine input of total nitrogen and phosphorus, along the Wadden Sea coast in the North Sea. During years when total nitrogen and phosphorus were above the climatology maximum, there was a lag signature in both PP and Chl a when PP exceeded the PP P90 threshold defined for the study area which was slightly more sensitive than Chl a P90. This technique represents an accurate means of determining disturbances in the environment both in the coastal and offshore waters in the NE Atlantic using remotely sensed ocean colour data.

Article Reference Through the correspondence: the little story of the “Spy bones”.
In the summer 1886, the Neandertal fossils of Spy were unearthed in the so-called Betche aux Rotches cave. Ever since, they have been through many events and have been the stake of discords, sometimes impassioned, between the various protagonists of their discovery and their conservation. The succession of these events will be redrawn here and the positions of each cleared up in the light of the rereading of two archives collections coming from the discoverers, namely the correspondence collection of Maximin Lohest, which is Mrs Dallemagne-Ophoven’s property, and the correspondence collection of Marcel De Puydt, handed over to the Royal Belgian Institute of Natural Sciences (RBINS), which we shall refer to as “the Vercheval collection”.

Article Reference Throwing Activities Among Neolithic Populations from the Meuse River Basin (Belgium, 4500–2500 BC) with a Focus on Adolescents.
The anterior band of the medial collateral ligament (MCL) is an important stabilizer for valgus stress at the elbow. When practised intensively and repetitively, activities using overhead throwing motions can injure this ligament and its insertion. If these activities occur when the epiphyses are not yet fully fused, traction forces can result in bony detachments in the area of the MCL insertion. This study was based on commingled graves found in 16 Middle and Late Neolithic caves from Belgium. We recorded the presence of MCL lesions on 196 humeri and studied the relation between lesions, siding, and robusticity. 5.1% of the humeri displayed MCL lesions, which affected only the right robust humeri. Our results suggest a social division in throwing activities in Belgium during the Neolithic. They also suggest that throwing practice started from a young age, which invites us to re-examine the role of teenagers in prehistoric societies.
