(Fagaceae) in a Mexican cloud forest Gerardo Sánchez Ramos Pedro Reyes Castillo Biología Plant Mexico Quercus herbivory cloud forest The interaction of the wood driller (Pantophthalmus roseni) and the red oak (Quercus germana) in thecloud forests of the Biosphere Reserve El Cielo at Gómez Farías, Tamaulipas, Mexico was studied. Fortymature individuals of Quercus germana were selected for comparison (20 healthy trees, 20 with severedamage, i.e. ³ 15 wood perforations caused by P. roseni). Healthy and damaged trees were measured forlevels of herbivory, percentage of foliar nitrogen, total phenols concentration and acorn production.Herbivory was significantly greater (P< 0.05) in healthy than in damaged oaks. The healthy group had 1.5times more leaf herbivory than the damaged group. Foliar nitrogen content in Q. germana (5.3%) showedsignificant variations in relation to the seasons (rainy season = 5.2% and dry season = 5.1%) andbetween damage groups, as well as in the interaction of season and group. The damaged trees group had1.2 and 1.5 times more phenols concentration than the healthy group during the rainy season and dry Sánchez-Ramos & Reyes-Castillo: Interaction of wood driller and red oak46season, respectively. Acorn production was significant greater (P< 0.05) for the damaged group than thehealthy group. The importance of these results in understanding and managing thisinsect as a forest pest, as well as, the effects of herbivory in the cloud forests arediscussed. 2006 artículo científico 0065-1737 https://www.redalyc.org/articulo.oa?id=57522203 en http://www.redalyc.org/revista.oa?id=575 Acta Zoológica Mexicana (nueva serie) application/pdf Instituto de Ecología, A.C.
