Simulating vegetation processes along the Kalahari transect
The Sheffield Dynamic Global Vegetation Model has simulated the structure and net carbon exchange of vegetation at five sites along the Kalahari transect where there is a strong gradient in precipitation from 299 to 918mmyr . There has been a decline in precipitation of 8mmyr 1 along the whole of the transect since about 1970. Simulations of vegetation dynamics and structure indicate that this ...
متن کاملOptic flow asymmetries bias high-speed steering along roads.
How do animals and insects use visual information to move through the world successfully? Optic flow, the pattern of motion at the eye, is a powerful source of information about self-motion. Insects and humans are sensitive to the global pattern of optic flow and try to maintain flow symmetry when flying or walking. The environments humans encounter, however, often contain demarcated paths that...
متن کاملWork in Motion: Interpretation of Defects along the Roads
This paper reports findings based on an ethnographic study of an occupational group, the road inspectors, at the Swedish National Road AdministrationProduction. We examine current work practice where the inspectors conduct a truly mobile work, since they are constantly on the move. It is not a fact of movement between different work places, seeing that the continuous movement could be understoo...
متن کاملCharacterization of Biophysical Vegetation - Soil Dynamics along an Eco-climatic Brazilian Transect with Modis Vegetation Indices
Field measurements were conducted on 10 June through 21 July 2002 to collect biophysical data in support of MODIS validation studies. Leaf Area Index (LAI), Plant Area Index (PAI), Absorbed Photosynthetically Active Radiation (fAPAR), biomass, cover components, site characterization and soil characterization were measured. The study areas extended over an eco-climatic transect, from the cerrado...
متن کاملVegetation composition and structure of woody plant communities along urban
Urban forests adjacent to interstate corridors are understudied ecosystems across cities. Despite their small area, these forests may be strategically located to provide large ecosystem services due to their ability to act as a barrier against air pollutants and noise as well as to provide flood control. The woody vegetation composition and structure of forests adjacent to urban interstates is ...
