PTERIDOFITAS EN EL ESTADO DE QUERÉTARO, MÉXICO Y SU UBICACIÓN ECOLÓGICA

Abstract

Queretaro state is localized in the
central part of Mexico, has approximately
12,000 Km2 and presents the following
vegetation types: confers forest (FC), open
scrub forest (OSF), mountain rain forest
(MRF), oak-savannah (OS), deciduous
seasonal forest (DSF), semievergreen
seasonal forest (SSF), arid tropical scrub

subacuatic vegetation (ASV) and pine-oak
forest (POF) (Zamudio et al., 1992).
Beside, in this paper we included the
pteridophytes grow in forest PinusQuercus. This work presents the ecological
distribution of 48 genera, 175 species and
12 varieties of pteridophyte from Queretaro.
We make an analized about taxa distribution
and found the following: 32% of the species
are in MRF, 23% in OS , 10% are in ATS and
POFeach one, 9.6%in DSF, 6.1% in FC, 6.8%
in SSF, 1.3% in G and 0.68% in ASV and
scrub forest, many species are presented in
differents vegetation types.
