Le Haut Atlas de Rich de type Jurassien a connu une évolution morphologique en deux étapes : une anté-quaternaire qui a vu la mise en place des volumes montagneux et une quaternaire ou phase de remblaiements successifs. - (MCH)
La ville commerciale dans l'Etat isolé de von Thünen est présumée habitée par deux classes sociales: les pauvres et les riches. L'A. en déduit des modèles de consommation alimentaire et le pouvoir d'achat qui en résulte.

Richer farmers and agrarian change in Meerut District, Uttar Pradesh, India
The study begins with a review of Green Revolution research in India. The A. discusses about the crucial role of the investment patterns of richer farmers in governing the dynamics of rural industrialisation. Various characterisations of richer
The local environmental gradient and species richness in a coastal nature reserve in Maputaland, South Africa
Understanding the local heterogeneity of species richness has important implications for conservation in coastal regions with development pressure. In preliminary surveys on the Maputaland coast a distinct zonation of vegetation was observed
and it was hypothesised that local environmental variables influenced the gradient of species richness. Obtaining baseline data is important for underpinning development plans. - (AJC)
Moisture history and small mammal community richness during the latest Pleistocene and Holocene, Northern Bonneville Basin, Utah
Precipitation and net primary productivity are positively correlated in arid environments. Both variables are, in turn, correlated with mammal species richness, but this relationship is not necessarily positive. In the Great Basin of the arid
western United States, studies of the relationship between rodent species richness and precipitation have revealed only a positive relationship between these two variables. When latest Pleistocene and Holocene small mammal assemblages from the northern
Bonneville Basin are examined across a temporal moisture gradient, species richness declines as moisture declines. Therefore, the unimodal response model does not appear to apply to this region.
The influence of site conditions on plant species richness, plant production and population dynamics: comparison of two desert types
Two field sites in the Judean Desert, in close proximity to each other, were compared with regard to plant species richness, production, and population dynamics. Although having very similar climatic conditions, the two types differed in edaphic
Rhodolith-rich lithofacies of the Porto Badisco Calcarenites (upper Chattian, Salento, southern Italy)
This study describes the rhodolith-rich lithofacies of the Porto Badisco Calcarenites, an upper Chattian rhodalgal/larger foraminiferal-dominated unit exposed in the southern part of the Apulia Carbonate Platform (Salento Peninsula, Italy
). The lensoid rhodolith-rich lithosome at the base of the studied section is made of rhodolith rudstone and floatstone which infill a channel-like depression inherited from the substrate. Changes in the texture of the rhodolith facies and in the inner structure
