On the affinity of Isocypridinae and Herpetocypridinae, with redescriptions of four species of Ilyodromus Sars, 1894 (Crustacea, Ostracoda)
-
In previous studies, the high degree of similarity of some species of Ilyodromus Sars, 1894 (Herpetocypridinae) to species of another subfamily (Isocypridinae) was noted, calling for a revision of their systematic placement. Here, the systematics of Ilyodromus Sars, 1894 are revised within this context by redescribing four species and comparing these to other genera of Herpetocypridinae and Isocypridinae. Material for the four redescribed species (I. amplicolis De Deckker, 1981, I. dikrus De Deckker, 1981, I. candonites De Deckker, 1981, and I. williamsi (McKenzie, 1966)) was obtained from Museum Victoria and recollected topotypes. It was found that most genera within Isocypridinae share morphological characters that are diagnostic of the subfamily Herpetocypridinae. On these grounds, the transfer of Isocypridinae to the rank of Tribe Isocypridini Rome, 1965 of subfamily Herpetocypridinae Kaufmann, 1900 is proposed here to account for the present understanding of morphological similarity.

On the first Belgian record of the Eifelian (Middle Devonian) ammonoid cephalopod Subanarcestes (Suborder Anarcestina)
-
Ammonoid cephalopods are extremely rare in the Lower and Middle Devonian sedimentary rocks of Belgium, which contrasts with the neighboring sedimentary basins. However, searches in old collections and recent collecting efforts show that ammonoids do occur in these beds in Belgium, which allows to enlarge our knowledge of Lower and Middle Devonian ammonoid occurrences. Here, a record of the Eifelian (Middle Devonian) anarcestid ammonoid genus Subanarcestes is described for the first time from Belgium based on a specimen from the Jemelle Formation (Chavées Member). This specimen was collected more than a century ago by Eugène Maillieux at Trou Bodet near Couvin. It laid unrecognized as an ammonoid cephalopod for many decades in the collections of the Royal Belgian Institute of Natural Sciences, while being previously identified as Cryptoceras or ‘Nautilus’ fossil, which if correct, constituted Belgium’s oldest Nautilida fossil. Micro-CT imaging greatly helped in the taxonomic assignment of the specimen.

On the relative role of abiotic and biotic controls on channel network development: insights from scaled tidal flume experiments
-
Tidal marshes provide highly valued ecosystem services, which depend on variations in the geometric properties of the tidal channel networks dissecting marsh landscapes. The development and evolution of channel network properties are controlled by abiotic (dynamic flow-landform feedback) and biotic processes (e.g., vegetation-flow-landform feedback). However, the relative role of biotic and abiotic processes, and under which condition one or the other is more dominant, remains poorly understood. In this study, we investigated the impact of spatio-temporal plant colonization patterns on tidal channel network development through flume experiments. Four scaled experiments mimicking tidal landscape development were conducted in a tidal flume facility: two control experiments without vegetation, a third experiment with hydrochorous vegetation colonization (i.e., seed dispersal via the tidal flow), and a fourth with patchy colonization (i.e., by direct seeding on the sediment bed). Our results show that more dense and efficient channel networks are found in the vegetation experiments, especially in the hydrochorous seeding experiment with slower vegetation colonization. Further, an interdependency between abiotic and biotic controls on channel development can be deduced. Whether biotic factors affect channel network development seems to depend on the force of the hydrodynamic energy and the stage of the system development. Vegetation-flow-landform feedbacks are only dominant in contributing to channel development in places where intermediate hydrodynamic energy levels occur and mainly have an impact during the transition phase from a bare to a vegetated landscape state. Overall, our results suggest a zonal domination of abiotic processes at the seaward side of intertidal basins, while biotic processes dominate system development more towards the landward side.

On using a Sensor Observation Service as an INSPIRE-compliant download service
-
Due to the use of sensors, the volume of scientific data produced every day has become massive,, so there is a strong need to organize them and to set up a data infrastructure for their efficient management. Open access, FAIRness (Findable, Accessible, Interoperable and Re-usable) and INSPIRE-compliance are increasingly becoming the norm for (environmental) data management. In order to achieve complex aspirations such as FAIRness and INSPIRE-compliance a simple idea might help: “Collect Once, Use many times”. Data collected today must be stored, documented and published in order to increase their knowledge extraction and to allow for an efficient re-use in the future. With the multiplication of sensor deployments in monitoring programmes, the new challenge is to publish time-series efficiently using state-of-the-art technologies.
The MOMO project (MOnitoring and Modeling of the cohesive sediment transport and the evaluation of the effects on the marine ecosystem resulting from dredging and dumping operations) has been deploying tripod platforms consisting of ADCP and ADC sensor packages in the Belgian Part of the North Sea for the last two decades. These deployments generated considerable amounts of valuable data that are currently stored as csv-formatted text files that are not interoperable, both in terms of content and access protocol. The full potential of those data is currently safeguarded only thanks to the knowledge and expertise of the scientists involved in the project. The consequences of knowledge loss is therefore significant.
The objective of this work is to explore the merit of implementing an Open Geospatial Consortium Sensor Observation Service (OGC SOS) for the publication of FAIR INSPIRE-compliant time-series data. The INSPIRE directive must be applied to data by the end of 2020 so the question is: “can a data provider be INSPIRE-compliant using SOS without complex and heavy developments?”
The 52°North SOS implementation was chosen in this project, partly because they provide a complete open-source solution (database creation, SOS client and SOS viewer).
