Three general types of edgeseffects are identified and illustrated with examples from the North Carolina coastal plain. First, ecological edgeeffects may have a geomorphic expression owing to the biogeomorphic impacts of plants and animals
. This is illustrated by ant bioturbation along a forest-grass boundary. Second, edgeeffects may be associated with unique geomorphic controls along boundaries : ferricretes. Third, geomorphic edgeeffects may be associated with force-resistance differences along
landscape boundaries : field-edge eolian ridges. It is important to recognize that landforms and processes along edges may not be representative of those in the adjacent landscapes.

This research was designed to test for vegetational edgeeffects along road corridors through an old-growth beech-maple forest and to discern the effects, if any, of edge age, orientation, and adjacent vegetation structure on edge composition
Investigating landslide-related cracks along the edge of two loess platforms in northwest China
Cracks are widely developed along the edge of loess platforms in northwest China. Field surveys reveal that these cracks can be grouped into shallow and deeply penetrating ones. The former occur at a small distance from the platform edge, normally
penetrate into the top unsaturated loess with the penetration depth being controlled by the joints in loess. The latter penetrate deeper into the saturated loess farther away from the platform edge. These cracks control the inflow and drainage of irrigation
of soil stress states and the results of field test show that the deeply-penetrating cracks could have both positive as well as negative effects on slope stability.
3 dated structures up to 450 years in age display the effects of coastal weathering of the greenschist of which they are constructed. A variety of weathering form is present. The various topographic surfaces of the structures create variation

provides extensive edges along wich surface tension menisci can be drawn up, and evaluating the significance of this in the frictional retardation of flow was the primary objective of the experiments reported here. The main strategy used here to identify
the effects of surface tension is to reduce its value by chemical means and observe the effects on flow properties.
The effects of slumps on soil erosion and soil formation in a Romanian study area, in the Nyárádmagyarós Basin being part of the Nyárádmenti Hills are investigated in the paper. Field and laboratory measurements revealed that slumps particularly
intensified linear erosion along the edges of the area of slumps, furthermore, they contributed to the acceleration of erosion in the neighbouring agricultural areas, as well. Slumps contributed to the diversification of the pedological conditions, however
and effects are concentrated at the edges of state territories—ie, borderzones. It concludes that this case demonstrates that biopolitics operates through sovereign territorial controls and surveillance, practices of death and exclusion, and suspension
Intra-storm rainfall attributes were analyzed for 49 extreme storm events at 5 locations in the KwaZulu-Natal Drakensberg. Three stations located in the mountain foothills and two stations sited on the escarpment edge above 2800 m a.s.l. provide
research is needed to ascertain the association between storm structure and synoptic conditions, as well as the actual effect that within-storm distribution of rainfall has on runoff and soil detachment.
of these tectonic pulses as well as of their effects in landform development, particularly clear on the Campos de São Francisco at the highest area of the SE edge of the plateau, show that besides the climate-related Quaternary environmental changes significant

The AA. identified 11 main types of dunes, described their distribution, and estimated the areas they covered. Dunes generally became more complex moving from the north to the south of the study area, and from the edges to the inner areas
of the sand sea. The wind regime also became more complex moving towards the south due to the physical blocking and thermodynamic effects of the mountains and the Qinghai-Tibetan Plateau, as well as the complex underlying topography. The combination
the southern mountains. This general distribution of dune heights suggests that dune height was determined by a combination of sediment availability, airflow patterns, the blocking effect of mountains, and the underlying topography.

, produced fewer emissions than the neighbourhood of large single-family homes. Findings suggest that, while compactness may be most effective when it is coupled with high frequency transit, decoupling the pair and building compactness before or without
This paper looks at the effect of transit station accessibility on housing prices in these three cities, which are all located on the south-eastern edge of the Greater China region. The key finding is that accessibility impacts stand in an inverse
the critical length/depth (L/H) ratio below which edgeeffects become important is unknown. The AA. establish this critical L/H ratio by benchmarking infinite slope stability predictions against finite element predictions for a set of synthetic two-dimensional
Indiana. The combination with the width of edge-of-field buffer strips module of the SWAT model achieved the largest TP loads reduction. These findings demonstrate that improved representation of vegetative conservation practices in geospatial land cover
data sets are more effective in assessing the impacts of conservation buffers and grasslands on water quality through hydrologic modeling.
Topographical effects on the equilibrium-line altitude on glaciers
The most useful parameter to quantify the climatic effects on a glacier is the equilibrium-line altitude (ELA) : a line on the glacier where accumulation equals ablation. In this paper, the topographical and morphological effects on the ELA
