ESTUDIO DEMOGRÁFICO DE Emilia sonchifolia (ASTERACEAE) EN UNA FINCA CAFETERA DE ARMENIA, QUINDÍO, COLOMBIA

Abstract: RESUMENSe realizó un estudio con el fin de determinar la estructura demográfica de Emilia sonchifolia (L.) DC en una finca cafetera del Municipio de Armenia, Quindío, Colombia, donde se recolectaron datos durante cuatro semanas, en tres sitios: exterior, borde e interior del cultivo. Usando parámetros calculados a partir de los datos de campo, se construyó un modelo logístico para describir el comportamiento poblacional de E. sonchifolia en el tiempo. Se encontraron diferencias significativas en las variables:… Show more

“…In the demonstration of the four cases contemplated in Proposition 2, it was verified that all the eigenvalues are real; specifically, in expressions (11), ( 12), ( 14)-( 17), (19), and (20), it was evidenced that no possibility exists of having complex eigenvalues, because all the radicands are positive.…”

“…The regulatory effect of this factor is clear; when the number of immature CBBs is very close to the carrying capacity, that is, when , then , and, hence, growth is inhibited. This regulation factor has been used in different contexts, such as population dynamics studies of the dengue-transmitting mosquito Aedes aegypti , as in [ 17 , 18 ], and a demographic structure study of the plant Emilia sonchifolia , as in [ 19 ]. Moreover, the mortality rate of immature CBBs due to environmental factors is denoted by the parameter ; then, the term represents the average number of immature CBBs that die per unit of time.…”

“…Entre las familias botánicas con potencial insecticida para el control de A. aegypti se encuentra la familia Asteraceae (Bessada et al 2015, Sukhthankar et al 2014, Tennyson et al 2015. Esta familia constituye una de las más grandes de plantas vasculares, comparable en complejidad y número de especies (25.000 aproximadamente) con las orquídeas (Bessada et al 2015, Duarte et al 2015. Después de Brasil (2.000 especies) y Perú (1.655 especies), Colombia es el país con más especies (1.420) descritas en América del Sur (Jørgensen et al 2011, Silva y Andrade 2013.…”
