|Description:||The natural regeneration dynamics of Theobroma subincanum Mart. (Malvaceae) around canopy gaps created by tree felling due to selective logging was assessed. For that, an experiment located in the Experimental Field of Embrapa Eastern Amazon in Moju municipality, PA, Brazil was carried out. Nine logging gaps were selected, and four strips of 10 m x 50 m were installed in each of these gaps following the cardinal directions. These plots were split in five 10 m x 10 m plots numbered from 1 to 5 from the gap?s border toward the forest. In plots 1, 3, and 5 and in the gap?s center 2 m x 2 m plots were installed to monitor individuals ≥ 10 cm in height and < 5 cm in DBH. In most of the variation factors analized, Theobroma subincanum presented higher recruitment rate in period 1 (1998-2000), since the competition for light were less intense. In period 2 (2000-2010), under a possible lower luminosity and higher competition, RR was lower for all factors analyzed. In relation to gap size, T. subincanum presented the best results in RR around medium size gaps. The distance of 20 m in relation to the gap center, with intermediary sunlight condititions, T. subincanum presented higher RR. The population of T. subincanum had better performance under intermediate light conditions.|
