                         monitored fire behavior and depth of fire penetration in the

                         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.",
