Caracterización morfológica y genética de las poblaciones de Abies en Hidalgo, México: importancia de la identidad taxonómica para el aprovechamiento forestal

Antecedentes: Abies hidalgensis es una especie endémica del estado de Hidalgo, México, adscrita en la Lista Roja de la IUCN en la categoría VuD2, que se ha confundido con A. guatemalensis en algunas poblaciones donde hay extracción de madera en rollo reportada como A. religiosa, lo que genera duda sobre las o la especie que se distribuyen y aprovechan en el estado de Hidalgo. Preguntas y / o Hipótesis: ¿Qué especie o especies del género Abies se distribuyen y aprovechan en Hidalgo, México?,¿Cuál es la distribución geográfica de A. hidalgensis? Especies de estudio: Abies hidalgensis, A. religiosa. Sitio y años de estudio: Municipios de Acaxochitlán, Acoculco, Agua Blanca de Iturbide, Epazoyucan, Mineral del Monte, Pachuca, Singuilucan, Tenango de Doria, Tepeapulco y Zimapán, en el estado de Hidalgo. Años 2015 a 2017. Métodos: Se analizaron 18 caracteres morfológicos mediante análisis de funciones discriminantes. Se estimó la diferenciación genética a partir del análisis de tres microsatélites nucleares desarrollados para A. guatemalensis. Resultados: Abies hidalgensis se distribuye al sureste y Abies religiosa en la zona centro-sur de Hidalgo. Los caracteres morfológicos distintivos son: canales resiníferos, forma del ápice, y caracteres morfológicos asociados a los conos ovulados y las semillas. Los estudios genéticos indican que Abies sp. muestra mayor divergencia y diversidad genética con respecto a A. hidalgensis y A. religiosa. El coeficiente de endogamia es mayor en A. religiosa. Conclusiones: En el estado Hidalgo se distribuyen dos especies del género Abies.
