Padrões da fragmentação do habitat na Cuesta de Botucatu (SP)
The overall goal of the present work was to continue studying habitat fragmentation in the Botucatu Cuesta, SP, Brazil, in a 18422-ha study. Landsat-5 TM images were used and a technique was developed to subtract data other than vegetation data from the scene. Thus natural vegetation thematic map...

The overall goal of the present work was to continue studying habitat fragmentation in the
Botucatu Cuesta, SP, Brazil, in a 18422-ha study. Landsat-5 TM images were used and a technique
was developed to subtract data other than vegetation data from the scene. Thus natural vegetation
thematic maps for different dates (1986 and 1993) were generated. The analysis of 1986 and 1993
spatial data revealed that habitat fragmentation in the study area was unstable. The process presented scale distinction, i.e., 1) in the largest patches subset the phenomenon was non-fractal
and patch size decreased following a linear tendency; 2) in the intermediary size subset of patches,
the phenomenon was non-fractal and patches size decreased in an increasing geometric progression;
3) in the smallest patches subset, the phenomenon was fractal, divided patches tending to follow a
geometric progression. |
