“…It is likely that the increase in the number and size of clearings at this site in the past decade due to tree felling is related to the survival of a large number of beech seedlings that germinated in the 2012 seed year (Rodríguez-Ramírez et al 2013) and of small saplings whose seeds germinated in the 2005 seed year (Godínez-Ibarra et al 2007). A similar explanation has been given for other beech forests in Mexico and in North America subject to different sources of high or frequent disturbance (Peters 1995, Williams-Linera et al 2003, Busby et al 2008.…”

“…wind, fire, logging) on plant population structure and dynamics. In fact, the temperate forests of North America, including Mexico, have experienced a complex history of natural and anthropogenic disturbances (Rzedowski 1978, Cowell & Hayes 2007, Busby et al 2008, Bradshaw et al 2010, Jardel-Peláez et al 2014.…”

“…According to a number of authors, a dynamic population structure in tree species means that they have a high potential for regeneration and for growing under environmental conditions favorable for the establishment of their seedlings (Lorimer & Krug 1983, Godínez-Ibarra & López-Mata 2002, Busby et al 2008, Boyce 2012, Pérez-Paredes et al 2014. In the case of Fagus grandifolia subsp.…”

“…In the United States, Lorimer (1980) dated beech trees over 280 years old and with diameters up to 110 cm. Busby et al (2008) estimated the age of Fagus grandifolia populations in northern New England in order to characterize the establishment of this species, finding trees with ages from 26 to 204. Williams-Linera et al (2000) found a narrower range of ages, from 70 to 120, in a Fagus population located in the Acatlán volcano in Veracruz, which was attributed to a severe disturbance in the past that had caused forest regeneration.…”

The highest densities and largest areas of Fagus grandifolia subsp. mexicana in Mexico grow in the cloud forest of the state of Hidalgo. Although this taxon is endangered, there is little information about its population structure. This study provides data on the structure of heights, diameters and ages of Fagus in three populations in Hidalgo. Additionally, information was obtained on the structure of the beech forests, whose canopy is dominated by Fagus. At each locality, three to five 400 m 2 sample plots, depending on the size of the respective forest, were randomly selected. Within each plot, density and basal area of each species of tree and shrub with diameter greater than 2.5 cm (1.30 m) were estimated. At the species level, populations are dynamic, with a high percentage of young individuals; however, at one of the localities, changes have occurred in the last decade due to anthropogenic activity, and the structure of sizes and diameters in the youngest age categories has changed. Diameter was a good indicator of the age of the trees. At the community level, the dominance of Fagus and other species differed between localities, which is probably related to the degree of disturbance. Population and community structure are related and could be considered as indicators of changes in environmental conditions in the recent past and today. Key words: Age structure, cloud forest, diameter classes, dendrochronology, Fagus grandifolia subsp. mexicana Estructura poblacional de Fagus grandifolia subsp. mexicana en el bosque mesó-filo de montaña del estado de Hidalgo, México Resumen Las poblaciones de Fagus grandifolia subsp. mexicana con mayor densidad de individuos y con mayor extensión territorial de México se desarrollan en el bosque mesófilo de montaña del estado de Hidalgo; dado que este taxón se considera en riesgo de extinción, el objetivo del presente estudio fue aportar datos sobre su estructura de alturas, diámetros y edades en tres poblaciones de Hidalgo. Adicionalmente, se obtuvo información sobre la estructura de los bosques de haya, en los que Fagus domina el dosel. En cada localidad se establecieron al azar entre 3 y 5 parcelas de muestreo de 400 m 2 cada una, dependiendo del tamaño de cada bosque. Dentro de cada parcela se estimó la densidad y área basal de cada especie de árbol y arbusto con diámetro mayor a 2.5 cm, a 1.30 m de altura. A nivel específico, las poblaciones son dinámicas, con un alto porcentaje de individuos jóvenes; sin embargo, en una de las localidades, han ocurrido cambios en la última década por actividades antropogénicas y la estructura de alturas y diámetros en las primeras categorías de edad se ha modificado; el diámetro resultó ser un buen predictor de la edad de los árboles. A nivel comunitario, la dominancia de Fagus y otras especies difirió entre localidades, lo que probablemente se relacione con el grado de perturbación. La estructura poblacional y comunitaria están relacionadas y podrían ser consideradas como indicadoras de cambios en las condiciones ambientales ...

“…There have been several reports of recent local or more global increases in AB abundance in the temperate forests of eastern North America (e.g., Beaudet et al 1999;Forrester et al 2003;Duchesne et al 2005;Busby et al 2008) as well as in SM (Siccama 1971;McIntosh 1972;Abrell and Jackson 1977;Runkle 1990;Fain et al 1994;Poulson and Platt 1996;Foré et al 1997). Several interacting factors can play a role in determining the abundance of AB, including its low palatability to deer, its ability to reproduce vegetatively, its susceptibility to beech bark disease, and its response to various types of disturbances including ice storms and human activities such as harvesting (e.g., Rhoads et al 2002;Brisson and Bouchard 2003;Leak 2006;Beaudet et al 2007;Long et al 2007;Runkle 2007;Busby et al 2008;Takahashi and Lechowicz 2008;Takahashi et al 2010). A recent study also suggests that the distribution of SM and AB is related to a major change in small-scale disturbance history (Gravel et al 2010).…”
