Temporal dynamics of dwarf mistletoe infestation (Arceuthobium globosum and A. vaginatum) in Zoquiapan (Iztaccíhuatl Popocatépetl National Park), Mexico

Dwarf mistletoes are forest para­sites of great impact on temperate forests, both at the biological and the economical level; however, little is known about the temporal dynamics of their infestation. The aim of this study was to know how the incidences of Arceuthobium vaginatum and A. globosum chan...

Dwarf mistletoes are forest para­sites of great impact on temperate forests, both at the biological and the economical level; however, little is known about the temporal dynamics of their infestation. The aim of this study was to know how the incidences of Arceuthobium vaginatum and A. globosum change through time in the Zoquiapan region, inthe Iztaccíhuatl Popocaté­petl National Park, Mexico. For two and a half years (november 2008 to may 2011), it was registered the incidence of dwarf mistletoe (pro­portion of infected trees), hosts abundance, and the abundance of pines smaller than 2 m in height on 24 plots of 3 300 m2. It was found that infestation dynamics varies greatly, between species and plots, and that A. vaginatum showed a greater incidence than A. globo-sum (Z = 44.09, P < 0.000 1). Also, the occurrence of fires and logging apparently affected the mistletoe incidence, and even, in some cases, mistletoe regrowth was observed. The incidence of A. vaginatum had a negative correlation with small pines abundance (rs = - 0.414, P < 0.05), which could be indicating that there is a negative effect on sapling recruitment. It is necessary to incorporate the occurrence of stochastic phenomena (like fires) to dwarf mistletoe management programs, to improve the conser­vation of forest resources.Archive XML (SciELO)  Los muérdagos enanos se encuentran entre los parási­tos forestales que tienen mayor impacto biológico y económico en los bosques templados; sin embargo, se sabe poco acerca de la dinámica temporal de la infestación. El objetivo de este trabajo fue conocer cómo cambia en el tiempo la incidencia de Arceuthobium vaginatum y A. glo­bosum sobre Pinus hartwegii en la región de Zoquiapan, dentro del Parque Nacional Iztaccíhuatl Popocatépetl, México. Durante dos años y medio (noviembre 2008 a mayo 2011) se registró la inciden­cia de muérdago (proporción de árboles infestados), la abundancia de hospederos y la abundancia de pinos menores a 2 m en 24 parce­las de 3 300 m2. Se encontró que la infestación es altamente variable entre fechas, especies y sitios, sin embargo, A. vaginatum mostró una mayor incidencia que A. globosum (Z = 44.09, P < 0.0001). Asimismo, la ocurrencia de incendios y la tala parecen haber afectado la inciden­cia de los muérdagos, e incluso, en algunos casos, se observaron rebrotes severos. La incidencia de A. vaginatum tuvo una correlación negativa con la abundancia de pinos menores a 2 m (rs = - 0.414, P < 0.05), por lo que esta especie pudo estar afectando el recluta­miento de individuos juveniles, mientras A. globosum no mostró una correlación significativa. Es necesario tomar en cuenta los sucesos estocásticos (como incen­dios) en los planes de manejo del muérdago enano, para mejorar la conservación de los recursos forestales. Archivo XML (SciELO) Universidad Autónoma de Tamaulipas 2015-07-20 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf text/html application/xml https://revistaciencia.uat.edu.mx/index.php/CienciaUAT/article/view/705 10.29059/cienciauat.v9i2.705 CienciaUAT; Vol. 9 No. 2: January-June 2015; 06-14 CienciaUAT; Vol. 9 No. 2: Enero-Junio 2015; 06-14 2007-7858 2007-7521 spa https://revistaciencia.uat.edu.mx/index.php/CienciaUAT/article/view/705/354 https://revistaciencia.uat.edu.mx/index.php/CienciaUAT/article/view/705/534 https://revistaciencia.uat.edu.mx/index.php/CienciaUAT/article/view/705/574
