Concepts in tropical geomorphology are briefly outlined together with their basic observations and arguments-climatically controlled exogenic forces are most active due to the high temperatures and humidity, resulting in intensive weathering
On the south German peneplain relics, the weathering residues show that, on quite different rocks, very similar features may be recognized by micro scale analysis. Therefore, a similar genesis can be assumed with regard to weathering and thus also
to relief, despite the great petro-variation. The main reason is the intense chemical weathering under a climate similar to the tropical climate of today.
Le relief, le climat et l'épaisseur du profil d'altération sont les principaux facteurs de formation des surfaces striées. Le relief étagé du paysage tropical, illustré par le plateau de Mahabaleshwar où les processus fluviatiles agissent jusqu'à

AA. provide an overview of the geomorphic evolution from tropical peneplanation in the Cretaceous and of the stages of karstification beginning with the Oligocene. The main goal of investigation was to understand the role of the Keszthely Mountains

The Upper Rio Negro basin, under a constantly humid equatorial climate, is a low-altitude extensive peneplain. Prevailing soils are oxisols and spodosols, and their distribution is usually related to the lithology of the parent materials. Six major

Delineation of boundary between tropical/subtropical in the middle section for eco-geographic system of South China

. New concepts of tropical, annual tropical, true tropical and tropical fluctuating zone are formed to understand tropical area. Based on the indexes of climate, vegetation and soil, boundaries of tropical, annual tropical, true tropical and tropical
fluctuating zone of the study area are established. The tropical fluctuating zone explains different locating of different researchers. This paper also puts forward a new method to display boundary for eco-geographic regions.
The A. briefly reviews major themes in published tropical forest research between 1991 and 1992 inclusive in an attempt to identify what questions are believed to be important.
Biogeography ; Ecology ; Ecosystem ; Forest ; Habitat ; Photosynthesis ; Tree species ; Tropical rain forest
The A. reviews the mainstream ecological literature from 1994 to 1995 to gauge the importance of ecophysiological studies in understanding the ecology of tropical rain forests.
The A. reports on the progress in describing and explaining variation of biodiversity in tropical rain forests. He bases this review on a search of the 1997 editions of Ecology Abstracts, Ecological Abstracts and Forestry Abstracts.
