| description | The dispersal ecology of the pepper tree (Schinus molle L.), introduced from Perú to México in the sixteenth century, is studied in the surroundings of Teotihuacán, State of México. Only the cedar waxwing (Bombycilla cedrorum) was consistently observed eating its fruits, despite of the presence in the study area, of many of the birds reported as dispersers. Germination ests show that the seeds eaten by birds, or those in which the exocarp was removed, germinate faster and have a higher percentage germination. Fruits passing through the digestive tract of birds lose 8% of their total sugar content. The timing from ingestión to egestion was about 25 min. This interval is more than 50 times longer than the time the birds spend perching in the tree (5T= 27 sec). It is concluded that Bombycilla is one of the most important dispersal agents of Schinus in Teotihuacan. It probably played a major role in the rapid spreadof Schinus molle in the Mexican Central Plateau more than 400 years ago. The importance of this tree for ecological and evolutionary studies is discussed as the dates of introduction to different places in the world are documented. |

Se estudia, en Teotihuacán, la ecología de la dispersión del pirú (Schinus molle L.), un árbol introducido a México a mediados del siglo XVI. En esta área, la única especie animal que consistentemente se observó comiendo sus frutos fue el ave Bomillbyca cedrorum, aun cuando algunos de los pájaros mencionados en la literatura como dispersores se encontraban en la región. Pruebas de germinación indican que aquellos frutos que pasaron por el tracto digestivo de las aves, o aquellos en los que se removió el exocarpio, germinan más rápidamente y con mayor porcentaje que los frutos intactos. Al ser ingeridos y pasar por el tracto digestivo del ave pierden 8% de su contenido total de azúcares. El tiempo de paso por el tracto digestivo es de aproximadamente 25 min. Este lapso es más de 50 veces mayor que el tiempo de estancia de las aves en los árboles ( x= 27 seg). Se concluye que Bombycilla es uno de los dispersores más importantes del pirú en el área de Teotihuacán. Probablemente ha sido uno de los responsables de la rápida invasión del pirú en el Altiplano Central de México hace más de 400 años. Se discute la importancia de este árbol para estudios ecológicos y evolutivos pues se conoce bien la fecha de su introducción en diferentes lugares del mundo.
