GUZMAN-CORNEJO, Laura; SANCHEZ-MORALES, Andrés y PACHECO, Leticia. Ferns and lycophytes of the Cardonal Municipality, Hidalgo, Mexico. Rev. Mex. Biodiv. [online]. 2015, vol.86, n.3, pp.573-581. ISSN 2007-8706. https://doi.org/10.1016/j.rmb.2015.06.004.
A floristic research of ferns and lycophytes was made at Cardonal Municipality, Hidalgo. For this purpose, several samples of different herbaria were revised in order to get a preliminary list of the ferns and lycophytes of this zone. At the same time, botanical samples were collected in 6 different types of vegetation from February to April and September to October; every sample was identified, set, labeled and incorporated to the collection of the Metropolitan Herbarium (UAMIZ). There were found 63 taxa, of which 9 correspond to lycophytes; Asplenium gentryi, Pleopeltis platylepis and Selaginella ribae , are new records for Hidalgo. With the obtained data, an absence-presence matrix of species found in the different types of vegetation was made, it was analized through correspondence and grouping analyses to determine the species similarity found among sampled sites. The statistical analyses showed that Pinus , Quercus and tropical deciduous forests have a floristic composition of ferns and lycophytes independent between them, while the Juniperus forest, thorny and tropical scrubs, present a similar composition. The diversity of environmental conditions found at Cardonal confers a floristic richness greater or equal-in number of species-, to the one present in protected zones (3) of the state of Hidalgo.
