Modern pollen assemblages and vegetational history of the moraines of the Klutlan Glacier and its surroundings, Yukon Territory, Canada
Modern pollen assemblages have been studied from surficial lake muds and moss polsters collected from five vegetated ice-cored moraines of the Klutlan Glacier. The youngest vegetated moraine (K-II) is characterized by high pollen values for Salix
the fossil spectra on the first two canonical variate axes of the modern surface spectra.

Age profiles of modern African elephant populations are significantly affected by drought conditions that cause local die-offs. Subadult animals die in proportions that may be nearly twice what is recorded in live populations. Such biasing of death
sample age profiles might also have occurre during late Pleistocene die-offs of Mammuthus. This comparative study of modern and fossil proboscidean age structures supports a tentative interpretation that late Pleistocene extinction of Mammuthus (at least

) rose from north to south at 190 m per degree of latitude, subparallel to, and approximately 740 m lower than, the full-glacial equilibrium-line altitude (ELA) and about 1 370 m lower than the estimated modern ELA| (2) the difference between the full

After a summary of the modern pollen spectra from Sahelian sites, the A. reviews in the main section of the paper, results from pollen analyses of late Pleistocene and Holocene sediments, including new data from the western Sahel. A summary

THE HYDROLOGICAL RESEARCH LABORATORY AT MONTPELLIER IS RUNNING AN INVESTIGATION OF NEW SEWER SYSTEM DESIGN CALCULATION METHODS CAPABLE OF MEETING COMPLEX MODERN SEWERAGE PLANNING REQUIREMENTS AND JUSTIFYING THE IMPORTANT COSTS OF SUCH PROJECTS

LES RECHERCHES DE LA GEOMORPHOLOGIE MODERNE S'INTERESSENT ESSENTIELLEMENT AUX PROCESSUS D'EROSION ET D'AGGRADATION PARTICULIERS A CERTAINES ZONES CLIMATIQUES ET AUX CONDITIONS ECOLOGIQUES LOCALES. L'IMPORTANCE DES DEPENDANCES STRUCTURALES EST DE

In this paper, the new and old observations are used to argue that these classical longitudinal dunes are oblique to modern winds, Holocene winds, and possibly to Pleistocene winds. Computer graphics experiments demonstrate that many

Etude critique des deux systèmes mondiaux les plus modernes de classification des sols (7Approximation et FAO), en les comparant du point de vue de leur utilisation par l'Institut national d'édaphologie qui se base sur les systèmes européens

The traditional textbook scheme interpretation that karst phenomena are the result of rock-dissolving work of precipitation water is erroneous. It has been proved that rain-water in itself has scarcely any dissolving action on limestone. Modern
