in these reservoirs provides a basis for the reconstruction of the monsoon history. The two reconstructions, separated by only 150km, have some features in common and some striking differences. Both show maximum monsoon amounts in the early Holocene, with a roughly
two-thirds decrease to the present. Both show salinization in sub-Boreal time. Both show long intervals of near complete desiccation in the last four millennia.

Questions are discussed with regard to geomorphology as part of the fields of geography and geology, as well as the importance geomorphology has or might have for both disciplines. Using cases the author has worked on, it can be seen that landscape
research should not be carried out without resource to geomorphology. The examples quoted and the conclusions drawn both show what sort of major improvement can be achieved in co-ordinating work between neighbouring disciplines. (l'A.).

Dissolved organic matter and iron in a moorland stream were determined at 8 hour intervals over a 6 month period to examine relationships with streamflow. Regression of both solutes on discharge were positive and explained 50-70 % of the variance
in the solute data, but better predictions were obtained in both cases when a covariate reflecting temporal variation in the relationships was introduced. Variations in the regression of Fe on the dissolved organic matter were also identified, indicating

Biogeography

throughout the twentieth century. The review of recent literature suggests that it remains central to both disciplines.

Aslia lefevrei (BARROIS, 1882) and Neopentadactyla mixta (OESTERGREN, 1898) are mentioned for the first time along the Belgian coast. Both species are described and their spicules figured. Their distribution is shortly discussed. - (Author).

The AA. believe that in modelling hillslope processes, a combination of both theoretical and experimental approaches is needed as illustrated by several examples from the Louven laboratory.

Reports observations relating to both lateral and longitudinal variations in the size of talus clasts in northwest Ireland. The implications of these patterns, along with aspects of slope morphology, for talus slope development are then discussed.

The aim of the present study is to investigate if the effect of the separation vortex and wind speed up on the lee-side is reflected in the sediment. This is carried out using both parameters from the log-hyperbolic distribution and standard moments.

The paper examines the frequency of occurrence of both warm season and cool season lake effects. The monthly distribution of the different types of lake effect, weather conditions favorable to their development, and associated parameters are also

Les peuplements de poissons de la Camargue

Fish communities in the Camargue wetlands, both temporary and permanent marshes as well as irrigation and drainage canals, were studied from 1977 to 1980.

The results of the 1984 aerial counts of wintering waterfowl in the Senegal, Niger and Chad basins are given and discussed. Both palearctic and afro-tropical species of Anatidae are restricted to the Sahelian belt during the winter and do not enter
the Guinea savannas or the forest-savanna mosaic further south, even during the drought episodes. In such conditions, palearctic migrants and afro-tropical species both concentrate in a limited number of refuge areas within the Sahelian belt.

Comparisons of sedimentation rates obtained by Pb and pollen analyses of 1-m cores collected throughout the Potomac Estuary show good agreement in the majority of cores that can be analyzed by both methods. Most of the discrepancy between
significant displacement by reworking and/or mixing of sediments. Differences between the methods are greatest where uncertainties exist in assigning a rate by one or both methods (i.e., Pb trends and/or possible horizon assignments).

Both species are strictly nocturnal in their activities, with two activity peaks during the course of the night. In P. cuvieri, males cover twice as much distance per night as females do. In both species male have larger home ranges than females

Flandrian, a formation or just a name?

, although there only exist type areas of both series instead of type localities. Work is going to define the type section in both areas of the Flemish Coastal Plain. It would be useful to re-establish the Flandrian stage on basis of these new investigations

Broadly curved distorsions are stressed by the upheaval of both shores of the Straight of Gibraltar together with that of two areas on each side of the Alboran Sea: the Campo de Dalias, West of Almeria in Spain and the Beni Saïd, Westoff Melilla
in Morocco. Both areas are separated from the Straight of Gibraltar by subsiding littoral zones. Some weak, highly localized deformations due to a fault tectonics are perceptible on the Eastern Betic Cordillera coast. West and East of Almeria. The broadly

The AA. try to assess the nutrient status of the soils, both in the upland and the lowland areas, to examine the nutrient losses, and to determine needs for the improvement of agricultural soil fertility. Results from this study may broaden

The dating is based on new paleomagnetic polarity determinations and on the lithostratigraphic position of the fossils in the loess-paleosol sequence. The results confirm that both localities are older than the first occupation of Zhoukoudian. New

The equilibria of soil bodies are disturbed by tremors and other periodic phenomena, both rapid and slow motion, natural and anthropic, and local to regional in scope. Observations may be of present soil vibrations and of traces left by past soil

Arid geomorphology

studies and a growing sophistication in both laboratory and field research. The final two sections of the paper do however consider some recent papers on dunes as landforms and other aspects of arid and semi-arid geomorphology.
