Banco de semillas después de un incendio en un matorral xerófilo

Abstract

A través de la emergencia de plántulas estudiamos los efectos del fuego en el banco de semillas del suelo de un matorral xerófilo en dos años consecutivos. Comparamos su composición y abundancia en dos sitios, uno quemado y uno no quemado. Una proporción importante de semillas murió debido a las altas temperaturas alcanzadas por el fuego. La riqueza y diversidad de especies fueron negativamente afectadas. Estas variables mostraron diferencias significativas entre sitios y años. Después de un año, la abundancia y diversidad del banco de semillas alcanzaron mayores valores. En términos de riqueza dominaron las hierbas perennes y en términos de abundancia, dominó una especie arbórea. El fuego no fue un factor determinante en la composición de especies. Estos resultados son importantes para explicar los cambios en la vegetación después del fuego, especialmente si consideramos que este sitio es una reserva natural inmersa en un área urbana.
