Composición y abundancia de las pteridofitas en el bosque mesófilo de montaña del municipio de Tlanchinol, Hidalgo, México

Abstract

El conocimiento sobre la riqueza y distribución de las especies de helechos y licopodios en el estado de Hidalgo, es escaso por lo que el objetivo principal de esta investigación fue realizar un inventario de las especies de Pteridofitas, conocer sus patrones de abundancia y los sustratos de crecimiento en el bosque mesófilo de montaña del municipio de Tlanchinol, Hidalgo. El estudio florístico se basó en la recolecta exhaustiva de ejemplares en 30 sitios y en la consulta de especímenes en los herbarios ENCB, FCME, HGOM, IZTA, MEXU y XAL. Para estimar la abundancia de las especies se establecieron 24 parcelas de muestreo de 400 m2 cada una. Se identificaron 21 familias, 53 géneros, 130 especies y diez variedades. La completitud del inventario osciló entre 73.4 y 87%, de acuerdo con los estimadores de riqueza de especies Clench y ACE, respectivamente. Sólo el 19% de las especies presentó abundancias promedio mayores a cinco individuos/400 m2. La mayoría de las especies se desarrollan sobre suelo (58.1%) o son de hábito epifito (25.5%). Además, se citan 12 especies como nuevos registros para el estado de Hidalgo y cinco taxones que se encuentran en alguna categoría de riesgo dentro de la Norma Oficial Mexicana NOM-059-SEMARNAT-2010.
