bank in a xerophytic shrubland. Bol. Soc. Bot. Méx [online].
2010, n.86, pp. 11-21. ISSN 0366-2128. Through the seedling
emergence method we studied the effects of fire on the soil seed
bank of a xerophytic shrubland in two consecutive years. We
compared its composition and abundance in two sites, one burned
and one unburned. An important proportion of seeds died due to
the high temperatures reached by fire. In addition, species
richness and, diversity were also negatively affected. These
variables showed statistical differences between sites and
years. After one year, seed bank abundance and diversity reached
higher values. Dominant species were perennial herbs in terms of
species number, and in terms of seedling abundance the dominant
life form was a tree. However, fire was not a determinant factor
in terms of species compo
