| description | Mistletoe, a hemiparasitic plant, is the second most destructive agent for Mexican forests after the bark beetle. For this reason, in the present study, its infestation in the forest populations of Sierra Fría, Aguascalientes was examined in order to: a) understand the factors that influence the abundance of mistletoe; (b) determine the infestation level present in host species and (c) identify if there exists specific types of mistletoe that correspond to different species and sizes of the host and / or habitat. In January 2007, 20 sampling locations were selected within which two sampling units were established (UM) of 2500 m2. In every UM the height and diameter of all individuals (infected and uninfected) > 1 m in height were measured and the presence of mistletoe was recorded. Also recorded was the altitude, incline, slope orientation, level of disturbance and degree of infestation. The results indicate that the level of mistletoe infection shows positive association with altitude and orientation and a negative association with disturbance. It was found that as the size of dasometric attributes (height, diameter) increases so too does the degree of infection. Phoradendron bolleanum was the most abundant species of mistletoe, with Juniperus deppeana being its most common host. In contrast to that reported by other works, Sierra Fría forest populations are not found to be severely affected by mistletoe. Nevertheless, it is recommended that future studies be undertaken that allow for the understanding of the factors that shape the distribution and hemiparasitic-host interaction within and between populations, in order to assess real or future damage and to evaluate the selectivity towards certain host species and chemical changes from which trees suffer as a result of infection. |

Los muérdagos, plantas hemiparasíticas, son el segundo agente de destrucción de los bosques mexicanos después del insecto descortezador, por lo que en el presente estudio se evaluó su infectación en poblaciones forestales de Sierra Fría, Aguascalientes, esto con la finalidad de: a) conocer los factores que influyen en la abundancia de muérdago, b) determinar el grado de infectación que presentan las especies hospederas, c) identificar si existe especificidad del muérdago por especie y tamaño del hospedero y/o por hábitat. En enero de 2007 se seleccionaron 20 sitios de muestreo dentro de los cuales se establecieron dos unidades de muestreo (UM) de 2500 m2. En cada UM se midió la altura y diámetro de todos los individuos (infestados y no infestados) >1 m de altura y se registró la presencia de muérdago. Se registraron, además, la altitud, inclinación y orientación de la pendiente, nivel de perturbación y grado de infección. Los resultados indican que el grado de infección por muérdago muestra asociación positiva con la altitud y orientación y una asociación negativa con la perturbación. Se encontró que al aumentar en tamaño los atributos dasométricos (altura, diámetro) se incrementa el grado de infección. Phoradendron bolleanum fue la especie de muérdago más abundante, siendo su hospedero más común Juniperus deppeana. En contraste con lo mencionado en otros trabajos, las poblaciones forestales de Sierra Fría no se encuentran severamente afectadas por muérdago; sin embargo, se recomienda realizar estudios futuros que permitan comprender los factores que dan forma a la distribución e interacción hemiparásito-hospedero, dentro y entre poblaciones, con la finalidad de evaluar los daños reales o futuros, así como evaluar la selectividad hacia ciertas especies hospederas y los cambios químicos que sufren los árboles a través de la infección.
