[1] Regolith-mantled hillslopes are ubiquitous features of most temperate landscapes, and their morphology reflects the climatically, biologically, and tectonically mediated interplay between regolith production and downslope transport. Despite intensive research, few studies have quantified both of these mass fluxes in the same field site. Here we present an analysis of 87 meteoric Be measurem...

The long-term evolution of channel longitudinal profiles within drainage basins is partly determined by the relative balance of hillslope sediment supply to channels and the evacuation of channel sediment. However, the lack of theoretical understanding of the physical processes of hillslope-channel coupling makes it challenging to determine whether hillslope sediment supply or channel sediment ...

The purpose of mass wasting susceptibility assessment using a Geographic Information System is to assign, in a regional scale, places were these events are more probable to take place. Fernandes & Amaral (1996) consider that the main purpose of mass wasting susceptibility maps is to provide information about the probability of mass wasting occurrence, dividing the whole area in certain landscap...

Numerous inselbergs rise above the regional erosional surface in semiarid northeastern Brazil. The are underlain by Quixadá Pluton and cut cm-thick granite dike swarms. Five with abundant dikes from two different parts of pluton were selected to investigate role patterns evolution residual topography, including morphological features hillslopes. methods included field mapping landforms, structu...

A simple hillslope hydrological model predicting water movement on sloping shallow soils is developed. Unlike existing hillslope models, the new model can be used to predict flow for long records of climatological data and it can be easily extended to include preferential flow. It compares favorably to other models with more restrictive input requirements. Its application is illustrated for exp...

Current research has determined that traits involved in reproductive strategies and processes of seed dynamics should be studied together, and under varying environments, in order to clarify their roles in the ecology of plant communities. Here, we analyzed reproductive traits (allocation to reproduction, efficiency of seed production, and seed size) at the community level and their relationshi...
