^len^aPhenology of the tree Elaeagia uxpanapensis was studied from March 1994 to March 1998. This species is a canopy emergent in the A.M. Brenes Biological Reserve, Alajuela, Costa Rica. Fifteen mature trees were marked in order of appearance and observed every month using binoculars. A platform was built on one tree to better distinguish the transition from flowering to fruiting. Leaf abscission and budding were continuous throughout the year with several peaks, while flowering and fruit production occurred every 28 and 25 months, respectively. Leaf-fall was positively correlated with air temperature (n = 13, r = 0.44, p < 0.05), and fruiting with precipitation (n = 13, r = 0.37, p < 0.05) and relative humidity (n = 13, r = 0.39, p < 0.02). Bud formation was inversely associated with precipitation (n = 13, r = -0. 66, p <0.05) and relative humidity (n = 13, r = -0.61, p = 0.05)^les^aSe estudió la fenología E. uxpanapensis (n = 13), árbol maderable y emergente del dosel de la Reserva Biológica Alberto Manuel Brenes, Alajuela, Costa Rica, de marzo 1994 a marzo 1998. Se construyó una plataforma a 25 m de altura para la observación de la transición de floración a fructificación. La caída de follaje y brotes foliares fueron continuas, y la floración (cada 28 meses) y la fructificación (cada 25 meses) fueron supranuales y prolongadas. La caída de follaje se asoció significativamente con temperatura ambiental (n = 13, r = 0.44, p < 0.05), así como la fructificación con precipitación (n = 13, r = 0.37, p < 0.05) y humedad relativa (n =13, r = 0.39, p = 0.05) . La aparición de brotes foliares se asoció inversamente con la precipitación (n = 13, r = -0.66, 5%) y humedad relativa (n = 13, r = -0.61, p < 0.05)
