Similar to the classical North American frontier territory, both the East European steppe and the Great Hungarian Plain are peripheral zones. In the present paper an attempt is made to define the concepts of frontier and periphery. Which were
the frontier territories in the past, and which are they nowadays ? The unique development of the Great Hungarian Plain has been studied in depth by Hungarian experts of historical and urban geography. The essay presents the evolution of the frontier zone
of the East European - i.e. Ukrainian - steppe from the 16th through 20th centuries. The research results on the Great Hungarian Plain are applied to understand the development of the Ukrainian steppe territory as a marginal zone. - (AM)

In agricultural basins of the southeastern coastal plain there are typically large disparities between upland soil erosion and sediment delivered to streams. This suggests that colluvial storage and redistribution of eroded soil within croplands

A partir de l'exemple de la basse plaine de la RDA, l'ouvrage présente les caractéristiques naturelles du territoire en vue de l'utilisation qu'on peut en faire. L'exploitation du milieu naturel est déjà relativement poussée et les structures
naturelles sont caractéristiques des régions de plaine de l'Europe centrale septentrionale constituées, elles aussi, de sédiments quaternaires meubles. (HL).
Amino acid enantiomeric (D/L) ratios in the mollusk Mercenaria are compared with recently published biostratigraphic and/or U-series solitary coral data from 22 Quaternary localities on the central and southern Atlantic Coastal Plain. In all cases
, if the U-series data are used as age calibrations for the D/L values, latitudinal trends of isochronous D/L values are highly variable and conflict with trends expected from the present temperature gradient.

The preferred habitats for baldcypress are common features in the alluvial valleys of the Coastal Plain. In contrast, they are mostly absent in the surrounding regions where swamps and abandonned channels occur relatively infrequently
. the coincidence of the northern limits of baldcypress and the Fall Line boundary of the Coastal Plain strongly suggests that its distribution is controlled by the avaibility of suitable habitats for regeneration. The AA. evaluate this hypothesis by examining
the distribution of baldcypress in river valleys of six streams that flow from the upland provinces into the Coastal Plain.

In this paper, the coastal plain of south Hangzhou Bay is taken as the case study to explore the impact of land use change (soil tillage, cultivation, fertilization, irrigation, drainage activities) on the nutrition situation and quality evolution
Subsurface data from the Miranda coastal plain, Firth of Thames, confirm that shell ridges between Kaiana and Miranda are true cheniers. Surveys of a modern chenier indicate that coarse sediment and shell form sand-bars on the foreshore
