Relación del tamaño de la sámara con la dispersión de Gallesia integrifolia (Phytolaccacea) en el sur del Ecuador

Abstract

Abstract: In the present work, the relationship between the size of 200 Gallesia integrifolia samaras with the distance and dispersal speed in a closed environment without the presence of air currents and in one with the presence of wind was analyzed and compared, using two experimental heights, to one and two meters. In the open environment, it was evidenced that the larger the samaras, the greater the dispersion distance, in the two experimental heights. On the other hand, in the closed environment an opposite effect was presented. Regarding the dispersion speed, only in the closed environment at one meter a defined pattern was not found. In the open environment, the size of the seeds affected that the samaras stay longer in the air. Know the effect of morphological traits on dispersal, take advantage of a better understanding of the ecology of seeds based on morphological traits of the samaras, understand the dispersal and distribution processes of the species, and know the capacity of forest plants to face possible scenarios Climate change futures in dry forests.
