Article Reference 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.

Booklet Reference Strandingen en waarnemingen van zeezoogdieren en opmerkelijke andere soorten in België in 2019 [Strandings and sightings of marine mammals and remarkable other species in Belgium in 2019]
In 2019 51 harbour porpoises washed ashore: a low number compared to previous years. More than half of these animals were in a poor state of conservation, and for many no cause of death could be identified. Four harbour porpoises died due to bycatch in fishing gear, four others as a result of predation by a grey seal. The estimated density of porpoises at sea in June and August was approximately the average of the last years. The only other cetacean that was found stranded was a very decomposed common dolphin. As was the case last year, a solitary, sociable bottlenose dolphin was present for months in the region adjacent to French waters. Groups of bottlenose dolphins were observed on two occasions. More exceptional were the sightings of a humpback whale and a minke whale. The presence of seals at our coast is still on the rise. In the port of Nieuwpoort a permanent haulout site has established; it is frequently used by more than 10 harbour seals. Also sighting rates of grey seals are increasing. The increased presence of seals translates into increasing numbers of dead and dying seals on the beach: 47, the highest number ever recorded. SeaLife took care of 11 grey seals and 15 harbour seals. Two leatherback turtles and some ocean sunfish were observed in 2019. Their presence might have been related to an unusual influx of Atlantic water. For a stranded ocean sunfish, it is still being investigated which species it belonged to. Marine mammals remain very popular: some temporary or permanent exhibitions were opened in 2019, and the skeleton of a sperm whale that washed ashore in 1989 was excavated with the objective to preserve it and to put it on display.
