De jongste geologische geschiedenis van de Belgische Zeepolders

The lay-out of the soil map of the Belgian maritime plain (1947-1953) has made it possible to correct our present-day ideas about the formation of our maritime polders. The main fact in this formation is the Dunkirk transgression, which comprises three phases: the Dunkirk 1 transgression (2nd century B.C. to 1st century A.D.), the Dunkirk 2 transgression (4th to 8th century) and the Dunkirk 3 transgression, subdivised in two subsidiary phases : the Dunkirk 3A transgressive phase (11th century) and the Dunkirk 3B transgressive phase (12th century). In the course of each of these transgressive phases sediment layers have been deposited, which constitute the present surface of the polder plain. According to their geological constitution, five typical geographical areas in the polder plain can be distinguished: the ancient area, the intermediate area, the recent area, the historical Ostend polders and the drained marshes

Population genomic structure of the gelatinous zooplankton species Mnemiopsis leidyi in its nonindigenous range in the North Sea

Nonindigenous species pose a major threat for coastal and estuarine ecosystems. Risk management requires genetic information to establish appropriate management units and infer introduction and dispersal routes. We investigated one of the most successful marine invaders, the ctenophore Mnemiopsis leidyi, and used genotyping-by-sequencing (GBS) to explore the spatial population structure in its nonindigenous range in the North Sea. We analyzed 140 specimens collected in different environments, including coastal and estuarine areas, and ports along the coast. Single nucleotide polymorphisms (SNPs) were called in approximately 40 k GBS loci. Population structure based on the neutral SNP panel was significant (F-ST .02; p < .01), and a distinct genetic cluster was identified in a port along the Belgian coast (Ostend port; pairwise F-ST .02-.04; p < .01). Remarkably, no population structure was detected between geographically distant regions in the North Sea (the Southern part of the North Sea vs. the Kattegat/Skagerrak region), which indicates substantial gene flow at this geographical scale and recent population expansion of nonindigenous M. leidyi. Additionally, seven specimens collected at one location in the indigenous range (Chesapeake Bay, USA) were highly differentiated from the North Sea populations (pairwise F-ST .36-.39; p < .01). This study demonstrates the utility of GBS to investigate fine-scale population structure of gelatinous zooplankton species and shows high population connectivity among nonindigenous populations of this recently introduced species in the North Sea.

Space construction in media reporting: A study of the migrant space in the 'Jungles' of Calais

Media are intrinsically implicated in constructing and framing space as well as in the imagination of communities. This paper examines how media through the spatial construct of the ‘jungle’ premises the discourses of migration between the borders of UK and France. We argue that newspapers impose a cartography by invoking a social imaginary of a bounded community sustained through imagined boundaries. Metaphors such as the ‘jungle’ function as spatialisation techniques to not only renew the sacrosanct boundaries of a nation-state, but they also become instrumental tools in invoking fear, anxiety and the visceral in migrant discourses. Conceptually, the paper argues that media sustains ‘an imagined community’ by techniques of spatialisation which encode politics of space in migrant discourses. These discourses are central in sustaining and enacting a social imaginary, where space framing and construction become tools to imagine and locate communities and to exclude the ‘other’

The non-human interest story: De-personalising the migrant

We argue that newspapers deliberately employ techniques to dehumanise and depersonalise news stories in order to cultivate distance between the reader and human subject in newspaper accounts. We posit this as a dominant technique in discourses of immigration in newspaper discourses. In the process the migrant is narrated as the sub-human entrapped through socio-legal terminologies and deviance discourses that both silence and trivialise human suffering. We highlight the case study of the refugee settlement in Calais dubbed the ‘jungle’ to illuminate this phenomenon. We argue that the depersonalisation of immigration stories is a sustained technique in media to submerge the ethical and humanitarian paradigms presented by immigration
