AbstractFour small-celled taxa are presented and described — Planothidium werumianum, P. pumilum, P. rhombiculum and P. rostratoholarcticum. Planothidium werumianum, P. pumilum and P. rhombiculum are proposed as new to science and P. rostratoholarcticum as a new name for Achnanthes lanceolata var. rostrata Hustedt 1911. The latter, coming from Germany, is transferred to Planothidium in the species rank. The new name — P. rostratoholarcticum — is necessary to avoid a junior homonym, i.e., Planothidium rostratum (Østrup) Lange-Bertalot 1999, a species described from tropical Thailand. The new taxa were compared to several other, more or less similar small-celled Planothidium spp., such as P. rostratum (Østrup) Lange-Bertalot, P. minutissimum (Krasske) Lange-Bertalot, P. granum (Hohn & Hellerman) Lange-Bertalot, P. daui (Foged) Lange-Bertalot, P. frequentissimum (Lange-Bertalot) Lange-Bertalot and P. engelbrechtii (Cholnoky) Round & Bukhtiyarova. Significant differences could be found through light- and electron microscopic fine structure analysis. Planothidium pumilum and P. rostratoholarcticum occur mainly in eutrophic alkaline rivers and lakes with medium to high conductivity, likewise in estuaries, lagoons, and backwater of the North Sea and the Baltic Sea. Planothidium werumianum and P. rhombiculum were found in small carbonate-rich rivers originating from medium altitude mountains.

Abstract. Since Late Pliocene / Early Pleistocene, the River Rhine, as one of the largest European rivers, has acted as the only drainage system that connected the Alps with Northern Europe, especially the North Sea. Along its course from the Alps to the English Channel the river passes several geomorphological and geological units, of which the Upper Rhine Graben acts as the major sediment trap. Whereas the potential of sediment preservation of the alpine foreland basins is low due to the high dynamics of the system, and the area of deposition close to the North Sea was significantly affected several times by Pleistocene sea level changes, the ongoing subsidence of the Upper Rhine Graben offers a unique potential for a continuous sediment accumulation and preservation.

Complete Story

The “modern” fortifications at Piacenza are situated at a significant physical and cultural crossroads linking the Mediterranean and roads leading to Central Europe and the North Sea. This paper aims to include their historical bastion features and city walls within an open-air educational museum that is well integrated within the modern town. Starting from the original basis of a defensive nature conceived to mark boundaries and divide kingdoms, the plan is to build a park which, by means of a fully-equipped green belt, is able to narrate the story of the Siegecraft and Renaissance apse techniques. At the same time, the aim is to explain how such a system may serve as a valuable means of allowing sustainable urban transport along with that of respecting and highlighting cultural heritage. In order to tell the complete story, an attempt is made to describe how direct relief may relate to the “compact town.”

AbstractA recent find of a Middle Villafranchian (c. 2.35–2.10 Ma) Canis cf. C. etruscus in the trawlings from the Oosterschelde concerns the oldest dog known from the Netherlands and is the first appearance record of this canid in the North Sea Basin. It shows that the tribe Canini was dispersed beyond south central Europe up to the northwestern edge of the continent. The find confirms the lack of synchroneity and usefulness of the so-called ‘Wolf Event’.

Abstract. We present the distribution and C:N stoichiometry of dissolved organic matter (DOM) in the North Sea in two summers (August 2011 and August 2012), with supporting data from the intervening winter (January 2012). These data demonstrate local variability superimposed on a general pattern of decreasing DOM with increasing distance from land, suggesting concentrations of DOM are controlled on large spatial scales by mixing between the open North Atlantic and either riverine sources or high DOM productivity in nearshore coastal waters driven by riverine nutrient discharge. Given the large size and long residence time of water in the North Sea, we find concentrations are commonly modified from simple conservative mixing between two endmembers. We observe differences in dissolved organic carbon (DOC) and dissolved organic nitrogen (DON) concentrations and land–ocean gradients between the two summers, leading to an estimated 10–20 Tg difference in the DOC inventory between the two years, which is of the same order of magnitude as the annual uptake of atmospheric CO2 by the North Sea system, and thus significant for the carbon budget of the North Sea. This difference is not consistent with additional terrestrial loading and is more likely to be due to balancing of mixing and in situ production and loss processes across the North Sea. Differences were particularly pronounced in the bottom layer of the seasonally stratifying northern North Sea, with higher DOC and C:N ratio in 2011 than in 2012. Using other data, we consider the extent to which these differences in the concentrations and C:N ratio of DOM could be due to changes in the biogeochemistry or physical circulation in the two years, or a combination of both. The evidence we have is consistent with a flushing event in winter 2011/12 exchanging DOM-rich, high C:N shelf waters, which may have accumulated over more than 1 year, with deep North Atlantic waters with lower DOC and marginally higher DON. We discuss the implications of these observations for the shelf sea carbon pump and the export of carbon-rich organic matter off the shelf and hypothesise that intermittent flushing of temperate shelf systems may be a key mechanism in the maintenance of the continental shelf pump, via the accumulation and subsequent export of carbon-rich DOM.

There is no acknowledged corpus of Anglo-Saxon lawsuits. Scholars have had the benefit of Bigelow's Placita Anglo-Normannica for over a century, and this will soon be superseded by the definitive edition which has occupied Professor van Caenegem since 1952. But the nearest that Anglo-Saxonists have come to a counterpart is the set of thirty-five ‘Select Cases in Anglo-Saxon Law’ appended to the Essays in Anglo-Saxon Law, which four of Bigelow's fellow Bostonians published as a symbolic, if apparently unintended, celebration of America's origins in centennial 1876. The limitations of this admittedly useful exercise extend beyond the facts that three of its cases are not Anglo-Saxon at all, and that its editors were unable to distinguish between the Latin names for Dover and Canterbury. Since then, the selections of Harmer, Robertson and Whitelock have made many more texts generally available, but without isolating the procedural records from other ‘historical documents’. Mean-while, the English evidence was ignored in the impressive list which Hübner intended as the basis of Placita section in the Monumenta Germaniae Historica: that august institution has tracked Germanic footsteps across the Alps, the Rhine, the Pyrenees and even the Straits of Gibraltar, but it as seldom followed. the Anglo-Saxons across the North Sea.
