Abstract

This study analyzes the survival of the savanna oak (Tabebuia rosea) under the influence of wind and the germination of its seeds in the Azuero region of Panama. The main objective was to determine how dispersal distance, influenced by climatic variables such as wind speed, precipitation, and relative humidity, affects the viability and establishment of new seedlings. The research was conducted using an experimental and descriptive approach, selecting a reference tree and collecting seeds dispersed at different radii during the period of greatest seed fall (May 2025). Environmental variables were recorded, and germination tests were performed under natural conditions. The results show that the greatest seed dispersal occurred in May, coinciding with the strongest winds, reaching distances of up to 84 meters from the parent tree. However, successful germination was observed mainly after the start of the rainy season in May, when precipitation increased significantly and relative humidity rose, allowing seedling establishment at distances between 50 and 75 meters. The estimated survival rate was approximately 16%. This phenological pattern, where dispersal occurs during the dry season and germination at the beginning of the rainy season, confirms an adaptive strategy to maximize survival in tropical dry forest environments. These findings provide relevant information for the management and conservation of Tabebuia rosea in the context of climate change.
