abstract = "Extensive deforestation in the Amazon has created a highly
fragmented forest in regions with an extensive rate of land use
conversion and use of fire for land clearing, agriculture and
grassland maintenance. The forest on the interface with land
clearings suffers drastic changes in micro weather, vegetation,
and ecological processes. Those altered conditions are favorable
to sustaining understory fires after a prolonged drought. An
increasing amount of fire usage, coupled with large areas of
forest vulnerable to fire creates a new threat to the integrity
and sustainability of the tropical forests in Amazonia and
elsewhere in the tropical world. This paper presents the results
of experimental burnings conducted from 1997 to 2003 in Mato
Grosso. The study monitored the change in vulnerability of the
interface between primary forest and recent deforested patches,
monitored fire behavior and depth of fire penetration in the
undisturbed forest on the edge of land clearing. Keywords:
Tropical fires, fragmentation, microclimate, primary forest. -->
RESUMEN: Deforestaci{\'o}n extensiva en el Amazonas ha creado una
selva bastante fragmentada en regiones con tasas altas de
deforestaci{\'o}n y de uso del fuego para limpia y mantenimiento
de terrenos. El bosque en la interfase con estas deforestaciones
sufre cambios dr{\'a}sticos en microclima, vegetaci{\'o}n y
procesos ecol{\'o}gicos, los cuales son favorables para la
combusti{\'o}n bajo las copas despu{\'e}s de una sequ{\'{\i}}a
prolongada. Un incremento en el uso del fuego, aunado a una mayor
{\'a}rea de bosque vulnerable a incendios es una amenaza para la
integridad y sustentabilidad de selvas tropicales. Se presentan
resultados de estudios conducidos en Mato Groso de 1997 al 2003
como parte de experimentos para estudiar combusti{\'o}n de
biomasa, tasas de liberaci{\'o}n de carbono y flamabilidad de
selvas. Se monitorearon cambios en susceptibilidad a incendios en
la interfase entre el bosque y {\'a}reas recientemente
deforestadas durante la temporada de sequ{\'{\i}}a, al final de
la cual se desarrollaron quemas experimentales.",
