Evaluación en los cambios de afectación por Entorchamiento y Herbivoría en poblaciones de Espeletia argentea durante la temporada seca 2012-2013, en el Parque Nacional Natural Chingaza, Colombia
In this investigation project evaluated the changes in the levels of herbivory and entorchamiento in Espeletia argentea populations to two different height ranges of 3000 and 3200 meters during the dry season in the basin of Quebrada Calostros within the National Park Natural Chingaza, Cundinamarca. Biotic and abiotic factors directly influence individuals the presence of pathogens and progression of these diseases. In E. argentea recent problems have been documented with pathogens and herbivores, species important to keep track of these conditions determining the state of vulnerability of natural populations. Were quantified incidence and severity data for the damages of herbivory and entorchamiento in the population of E. argentea in the basin of Quebrada Calostros, where presented a constant incidence herbivory and increased incidence of entorchamiento in the two seasons sampled. In return the severity levels for both herbivory and entorchamiento are low, since the population has no values exceeding 22% for any of the age classes sampled in the two temporalities. It suggests a possible correlation between herbivory and increased for the dry season entorchamiento as malformations generates herbivory during leaf growth caused by pathogens or insects, expressed seeing these symptoms at time 2. Furthermore, the level of infection in the population entorchamiento E. argentea increased significantly in the dry season (2013) for the rainy season (2012), which suggests a possible disease progression over time with high disease topics related to temporality.
