“…Quercus humboldtii is considered a vulnerable species (Cárdenas & Salinas, 2006; Cárdenas et al, 2020) and is subject to special protection since 1975 when its commercial exploitation was banned. Despite this effort, the Andean oak forests are threatened by deforestation and other anthropogenic disturbances (Avella Muñoz, 2016; Salazar et al, 2020). In recent years, Q .…”

Epidemiological characterization of a disease associated with phytoplasmas in Andean oak, Quercus humboldtii Bonpland, in Bogotá—Colombia

Quercus humboldtii is the dominant tree species in oak forest ecosystems in the Colombian Andes, and approximately 15,000 trees have been planted in urban Bogotá. In Bogotá, Q. humboldtii is affected by phytoplasmas. The management of phytoplasmas relies mainly on control of the insect vectors. The aim of this work was to generate information on phytoplasmas affecting Q. humboldtii and the potential insect vectors involved. Phytoplasmas were detected by nested PCR and identified by restriction fragment length polymorphism or sequencing analysis of the 16S rRNA gene in 238 randomly selected urban trees, from 17 city zones. The prevalence of the disease was 80%, with phytoplasmas detected in 94% of trees. ‘Candidatus Phytoplasma fraxini’ was found in 54.6%, ‘Candidatus Phytoplasma asteris’ in 30.7% and mixed infections of both phytoplasmas in 8.8% of the trees. Phytoplasmas were observed in the phloem of infected trees by electron microscopy. ‘Ca. P. fraxini’ was more common than ‘Ca. P. asteris’ in both street and parks trees, but correlations between the phytoplasma and disease‐associated variables were not observed. The entomofauna of a subsample of 102 of these trees was examined. Representative specimens of seven orders were collected, with Hemiptera the most prevalent. Specimens of 17 Cicadellidae, one Membracidae and one Psyllidae species were collected. Cicadellidae species from subfamilies Aphrodinae, Deltocephalinae, Iassinae, Eurymelinae, Megophthalminae and Typhlocybinae were found, in which phytoplasma vectors have been reported previously. Specimens of two known Cicadellidae vector species were collected: Amplicephalus funzaensis (Deltochephalinae) and Exitianus atratus (Deltochephalinae). Phytoplasmas were assessed in 103 Cicadellidae specimens. ‘Candidatus P. asteris’ was detected in A. funzaensis (n = 3/16 tested), E. atratus (n = 2/10 tested) and Alebrini sp. 1 (n = 1/11) tested). The possible epidemiological implications of these findings are discussed.

“…En este contexto, la implementación del uso sostenible emerge como una parte esencial de la estrategia de conservación. Los progresos en la recopilación y desarrollo de investigaciones contribuyen al manejo forestal; no obstante, se requiere un esfuerzo particular en el fortalecimiento de las comunidades locales, ya que son ellas las que mantienen una interacción constante con estos ecosistemas y, en cierta medida, influyen en sus condiciones presentes y futuras (Avella & Cárdenas, 2010). Es precisamente por esta razón que el turismo orientado a la comunidad se reconoce como un catalizador fundamental para lograr la sostenibilidad en la industria turística en áreas rurales (Aguirre-Vélez & Mestanza-Ramón, 2022).…”

Community rural tourism is a driving force for local economic development by making sustainable use of a community's resources. The Juan Velasco Alvarado Hilly Dry Forest Private Conservation Area -JVA HDF PCA- has latent tourism potential, which to date, has not been properly exploited by the Juan Velasco Alvarado Peasant Community -JVA PC-. The objective of the study is to formulate a proposal for the development of community rural tourism of the JVA HDF PCA. A situational analysis of the tourist supply and demand of the area was carried out where Pilán Hill, the Inca Mine, the Jaguayes Salas and Cerezo were recognized as the most important tourist resources, whilst the main problem identified was the poor management of tourism in the area. JVA HDF PCA by the JVA PC. As a final result, a proposed action plan was prepared that proposes capacity building, the improvement of ecological infrastructure, and the formation of strategic alliances in order to achieve the sustainability of the natural resources management in the dry forest and the progress of the local community.

“…Postfire Quercus humboldtii resprouting and recruitment However, deforestation, agriculture, livestock production, and wildfires have likely caused the decline of this species (Avella, 2016;Fernández-Méndez et al, 2016) and its inclusion as Vulnerable (VU) on the IUCN Red List (Salinas and Cárdenas, 2007). Nevertheless, the Q. humboldtii forest communities host high levels of biodiversity, including 550 species of vascular plants, 200 species of birds, 55 species of mammals, and 30 species of amphibians (Pulido et al, 2006;Sáenz-Jiménez, 2010), and provide many benefits for people, such as clean water, food, medicinal plants, raw materials for construction, and domestic and industrial fuels, as well as services related to tourism and spiritual landmarks (Bello, 2006;Muñoz and Camacho, 2010).…”
