Fenología y asociación ecológica interespecífica de Ribes lehmannii Jancz en el páramo de Quimsacocha, microcuenca de Zhurucay

Abstract

In the south of Ecuador is the fourth part of endemic plants of the country forming part of the composition and exclusive floral diversity. Unfortunately, due to phenomena such as deforestation and climate change, many plant species are affected. In this region there is little knowledge about the ecology of endemic species. The objective of this research was to generate information on the phenological stages of Ribes lehmannii, ecological association, and relationship with environmental variables in the Quimsacocha páramo. Methodologically, 30 individuals with good phenotypic characteristics were selected; monitoring was carried out every fifteen days during 8 months and the environmental variables of precipitation, temperature, relative humidity and solar radiation were correlated with the phenological stages of flowering and fruiting, as well as their ecological value with respect to the species of their habitat. The results recorded that Ribes Lehmannii in the flowering phase has a high level of occurrence in the month of November and for the fruiting phase in the month of February. The flowering and fruiting phases were positively related to temperature and relative humidity. The species Paspalum bonplandianum, Lachemilla orbiculata, Calamagrostis intermedia were the most ecologically valuable. The main contributions of this study are to provide the phenological calendar of Ribes lehmannii, its behavior with environmental variables and its ecological value with the other species of its habitat.
