Distribución actual y potencial de la especie Passiflora ligularis en los Andes Ecuador, bajo escenarios de cambio climático

Abstract

This research work is developed to know the current and potential distribution of Passifllora ligularis in the Ecuadorian Andes under climate change scenarios, divided into three chapters according to the objectives: the first chapter refers to the diagnosis of the current situation of the species Passifllora ligularis in the Ecuadorian Andes by generating a georeferenced database that documents the presence and current status of this species in the region, making reference to the general characteristics of this species, describing the taxonomy, botanical characteristics, as well as the climatic and edaphological requirements that the cultivation requires for optimal production. In the second chapter, a database is generated based on the georeferenced species for the visualization and configuration of the layers and maps generated through specialized software. Determining the potential distribution under climate change scenarios for this species, the coordinates obtained were used for the modeling with Maxent and at the same time we worked with 2 climate change scenarios, 4.5RCP and 8.5RCP, in addition 19 bioclimatic variables related to physiological aspects of species growth were used. In the third chapter, conservation strategies are established. Carried out in the provinces of Carchi, Imbabura, Pichincha, Cotopaxi, Bolívar, Tungurahua, Chimborazo, Cañar, Azuay and Loja, carrying out a literary study to determine the current distribution of Passiflora ligularis subsp. granadilla, where it was identified that the adequate distribution ranges of the 8.5RCP trajectory increase with respect to the 4.5RCP scenario, this is explained under the premise that high Andean habitats have characteristics that favor the potential distribution of granadilla.
