Article Reference Predator effects on the feeding and bioirrigation activity of ecosystem-engineered Lanice conchilega reefs
Ecosystem engineers can considerably affect the community composition, abundance and species richness of their environment. This study investigates the existence of positive or negative feedbacks of species that compose the community in intertidal biogenic reefs constructed by the ecosystem engineer Lanice conchilega. This tubeworm creates attractive nursery and feeding grounds for the predatory brown shrimp Crangon crangon, while at the same time is preyed upon by C. crangon. The effect of the predation pressure exerted by C. crangon on the bioirrigation and feeding activity of the tubeworm is up until now unknown and it is hypothesised that these activities are affected by the high densities of C. crangon in the reefs. A mesocosm experiment was set up to investigate the effects of predation pressure on the bioirrigation and feeding activity of L. conchilega in the i) absence; ii) restricted presence; and iii) unrestricted presence of C. crangon. Bioirrigation was quantified by the decrease of an artificially introduced bromide (Br−) tracer, while feeding activity was measured from the incorporation of 13C via stable isotope analysis. The bioirrigation rate of the L. conchilega reef equalled about 30 L·m−2·d−1 andwas not affected by the presence of the predator. The food uptake of the tubewormwas however about three times lower in the unrestricted presence of C. crangon, presumably due to the retraction of the worm's body and tentacles in its tube induced by physical contact with the predator. Notwithstanding the impacted food uptake of L. conchilega, the tubeworm maintains its functional role in the presence of predators in soft-bottom intertidal areas.

Article Reference Primitive equoid and tapiroid mammals: keys for interpreting the Ypresian – Lutetian transition in Belgium.
Terrestrial mammal teeth, pertaining to the primitive horses Hallensia louisi and Propachynolophus levei and the tapiroid Lophiodon remensis, have been discovered at the base of the marine Lede Formation in the Oosterzele and Balegem sandpits, 10 km southeast of Gent. According to its calcareous nannofossil NP15 dating, the basal Lede Formation in that area belongs to the Middle Lutetian. Comparison with in situ records in the Paris Basin suggests a latest Ypresian origin for the mammals (reference-level MPIO) and consequently reworking. The Oosterzele and Balegem specimens most probably originate from erosion of the continental Aalterbrugge Lignitic Horizon (uppermost Ypresian), which is cropping out nearby. The additional reworked faunal and lithological components at the base of the Lede Formation suggest that also the Aalter Formation (top NP13-base NP14) and the overlying Brussel Formation (NP14), or certain parts of these, were deposited but subsequently eroded in that area. The depositional history of the Lede Formation, resulting from the interplay of tectonic uplift and eustatic sea-level changes, is detailed.

Article Reference Priorities for ocean microbiome research
Microbial communities have essential roles in ocean ecology and planetary health. Microbes participate in nutrient cycles, remove huge quantities of carbon dioxide from the air and support ocean food webs. The taxonomic and functional diversity of the global ocean microbiome has been revealed by technological advances in sampling, DNA sequencing and bioinformatics. A better understanding of the ocean microbiome could underpin strategies to address environmental and societal challenges, including achievement of multiple Sustainable Development Goals way beyond SDG 14 ‘life below water’. We propose a set of priorities for understanding and protecting the ocean microbiome, which include delineating interactions between micro- biota, sustainably applying resources from oceanic microorganisms and creating policy- and funder-friendly ocean education resources, and discuss how to achieve these ambitious goals.
