Article Reference Organic Matter Composition of Biomineral flocs and Its Influence on Suspended Particulate Matter Dynamics Along a Nearshore to Offshore Transect
The seasonal variation in concentration of transparent exopolymer particles (TEPs), particulate organic carbon (POC) and particulate organic nitrogen (PON) were investigated together with floc size and the concentration of suspended particulate matter (SPM) along the cross-shore gradient, from the high turbid nearshore toward the low-turbid offshore waters in the Southern Bight of the North Sea. Our data demonstrate that biophysical flocculation cannot be explained by these heterogeneous parameters, but requires a distinction between a more reactive labile (“fresh”) and a less reactive refractory (“mineral-associated”) fraction. Based on all data, we separated the labile and mineral-associated POC, PON, and TEP using a semi-empirical model approach. The model's estimates of fresh and mineral-associated organic matter (OM) show that great parts of the POC, PON, and TEP are associated with suspended minerals, which are present in the water column throughout the year, whereas the occurrence of fresh TEP, POC, and PON is restricted to spring and summer months. In spite of a constantly high abundance of total TEP throughout the entire year, it is its fresh fraction that promotes the formation of larger and faster sinking biomineral flocs, thereby contributing to reducing the SPM concentration in the water column over spring and summer. Our results show that the different components of the SPM, such as minerals, extracellular OM and living organisms, form an integrated dynamic system with direct interactions and feedback controls.

Article Reference Organic matter processing in a [simulated] offshore wind farm ecosystem in current and future climate and aquaculture scenarios
The rapid development of blue economy and human use of offshore space triggered the concept of co-location of ma- rine activities and is causing diverse local pressures on the environment. These pressures add to, and interact with, global challenges such as ocean acidification and warming. This study investigates the combined pressures of climate change and the planned co-location of offshore wind farm (OWF) and aquaculture zones on the carbon flow through epifaunal communities inhabiting wind turbines in the North Sea. A 13 C-labelled phytoplankton pulse-chase experi- ment was performed in mesocosms (4 m 3 ) holding undisturbed hard-substrate (HS) communities, natural sediment with infauna, and mobile invertebrate predators. Carbon assimilation was quantified under current and predicted future-climate conditions (+3 °C and −0.3 pH units), as well as a future-climate co-use scenario with blue mussel (Mytilus edulis) aquaculture. Climate change induced an increase in macrofaunal carbon assimilation as well as an organic enrichment of underlying sediments. Dynamic (non-)trophic links between M. edulis and other HS epifauna resulted in shifts among the species contributing most to the phytoplankton-derived carbon flow across climate scenar- ios. Increased inter- and intraspecific resource competition in the presence of M. edulis aquaculture prevented a large increase in the total assimilation of phytoplankton by HS fauna. Lower individual carbon assimilation rates by both mussels and other epifauna suggest that if filter capacity by HS epifauna would approach renewal by advection/ mixing, M. edulis individuals would likely grow to a smaller-than-desired commercial size. In the same scenario, ben- thic organic carbon mineralisation was significantly boosted due to increased organic matter deposition by the aqua- culture set-up. Combining these results with in situ OWF abundance data confirmed M. edulis as the most impactful OWF AHS species in terms of (total) carbon assimilation as well as the described stress responses due to climate change and the addition of bivalve aquaculture.

Article Reference Osteology and relationships of Luxembourgichthys (“Pholidophorus”) friedeni gen. nov. (Teleostei, “Pholidophoriformes”) from the Lower Jurassic of Belgium and the Grand Duchy of Luxembourg.
The osteology of Luxembourgichthys friedeni (Delsate, 1999) gen. nov. from the marine Toarcian (Grandcourt Formation, Lower Jurassic) of Belgium and the Grand Duchy of Luxembourg is studied in detail. This fossil teleost fish was initially assigned to Pholidophorus, a genus that recently received an emended diagnosis (Arratia, 2013). The cranial characters of L. friedeni considerably differ from those that now define Pholidophorus and the Pholidophoridae, excluding its attribution to both this genus and this family. In L. friedeni the posttemporal fossa is completely located on the lateral face of the braincase and not on the rear of the skull as usual. Such a position is unique among “Pholidophoriformes” and justifies the peculiar generic status of this taxon. L. friedeni possesses three specialized characters (a beryciform foramen piercing the anterior ceratohyal, arcocentra associated to the chordacentra and ovoid scales devoid of the peg-and-socket system) suggesting it occupies a position crownward of most “pholidophoriforms”, closer to Jurassic and younger teleosts with cycloid scales.
