  • The aim of this report is to open a small window on developments in physical geography which reflect the growth of interest in society-environment relationships and the current emphasis on applied research. (l'A.).
  • On the aeolianite-red sands relationship in coastal Natal in Palaeoecology of Africa and the surrounding islands. Volume 15. Southern African Society for Quaternary research. Proceedings.
  • Observations on the aeolianite-red sand relationships in Natal and Israel are reported and compared. It is suggested that only originally highly calcareous sands (over about 25 % CaCO) were cemented into aeolianite in Natal. At a lower content

  • Relationship between soil properties, soil moisture, and vegetation along loess-covered hillslopes, northern Negev, Israel in Arid and semi-arid environments. Geomorphological and pedological aspects.
  • Erosion et dispersion des produits phytosanitaires dans l'environnement
  • The authors attempt to show a relationship between the importance of the erosion and the dispersion of herbicials provoked by this erosion, in the Belgian loess area.
  • Climatic relationships of permafrost zones in areas of low winter snow-cover
  • degree days per year. The relationship works for Norway, Iceland Spitsbergen, Canada and the People's Republic of Mongolia. There are some marked variations in lapse rate from one environment to another. Calculations of past world climatic change based

  • d'Edmonton et de ses environs. - (JPB)
  • environments, it is possible to trace the thermal ranges of the various active periglacial landforms. Relationships between zonal permafrost landforms and permafrost zones are emphasized.
  • In areas with under 50 cm snow cover in winter, the permafrost zones can be defined by freezing indices and thawing indices. The relationship works for Norway, Spitsbergen, Canada and Mongolia, and since these include a very wide range of thermal
  • Well drained soils with a degraded Bt horizon in loess deposits in Belgium| relationship with paleoperiglacial processes
  • in permafrost aggrading in an environment with relatively high water supply from the subsoil. The degree of degradation, and its distribution in the landscape, can be explained in a much more satisfactory way by these processes associated with a periglacial
  • Evaluation of the climate for land suitability purposes. II. Evaluation for annual crops in a humid tropical environment
  • A method is presented to evaluate the climate for annual crops grown in a humid tropical environment, based on the variability concept, which was introduced earlier. An example is given, as well as some relationships between recorded yield data
  • High-concentration levels of heavy minerals in two volcanic soils from Colombia : a possible paleoenvironmental interpretation in Volcanic soils. Weathering and landscape relationships of soils on tephra and basalt.

  • Many features reported in the Appalachian region have been assigned a paleoperiglacial origin based on field relationships and their similarities with analogs active in present day actuoperiglacial environments. These forms include
  • CHARACTERISTICS OF THE STONE RUNS WHICH WERE IGNORED IN PREVIOUS ACCOUNTS, AND CONSIDERS THE SPATIAL RELATIONSHIPS OF THE RUNS WITH GLACIAL LANDFORMS, WITH OTHER SLOPE PHENOMENA AND WITH REMNANTS OF A REGOLITH OF CHEMICALLY ROTTED BEDROCK. IT IS CONCLUDED

  • The results, indicating a close relationship between climatic change and tree-growth response, demand that upper timberline management strategies be developed to take into account natural fluctuations as well as possible human impacts on the forest
  • Two approaches to this problem : 1) the analysis of recent debris flows within an Alpine environment, and 2) laboratory experiments, simulating debris flows under different conditions. Sedimentological characteristics of debris flow material
  • are discussed, as well as relationships between physical and sedimentological properties. Resulting criteria for the recognition of debris flow material are given and the role of temperature is treated briefly.
  • The present paper deals with a comparative study of three catchments in a hilly environment, to gain further information on high-stage discharges and sediment transport dynamics on a small-basin scale, as well to assess relationships between

  • Results of the study of the relationships between landsurface morphology and surficial geology in the forest-savanna zone of Sierra Leone. Examining the variations in gravel layer petrology within a catenary framework gave insights
  • of a close relationship between the size of the prey and that of the predator, emphasizes the dietary opportunism of Eremias olivieri. Such a diet is considered as adaptive to the scarcity of food resources of the semi-desertic environment of the Kerkennah
  • earlier ideas that they may be the products of partial melting of peridotite in hydrous conditions, whereas basaltic komatiites have been assumed to result from fractionation of dry melts. Where field relationships are known, boninites are found either
  • in ophiolite, or a fore-arc tectonic environment.
  • An attempt is made to demonstrate a causal relationship between the structure of the forest and the structure of its bird communities. The results allow a substantiation of the concept of forest alteration and the integration of ecological
